Opinion of the Court by
MOON, C. J.
Appellant Voieestream PCS II Corporation (Voicestream) appeals from the third circuit court’s June 18, 2001 judgment2 that affirmed the decision of appellee County of Hawaii Planning Commission (HCPC), requiring Voicestream to obtain a special permit in connection with its development of a wireless communication network on the island of Hawaii. Briefly stated, Voices-tream’s proposed construction in this ease involves the installation of a “stealth” or cellular antenna concealed in a “false” chimney attached to a single family farm dwelling, including accompanying communications equipment placed in an adjacent garage. The single family farm dwelling is situated in a state land use agricultural district and is, therefore, subject to the uses prescribed in Hawaii Revised Statutes (HRS) chapter 205.
On appeal, Voicestream contends that the circuit court erred in affirming the HCPC’s .decision that Voieestream is required to obtain a special permit. For the reasons discussed herein, we reverse the circuit court’s June 18, 2001 judgment affirming the decision of the HCPC.
[345]*345I. BACKGROUND
A. Factual Background
Voicestream is a wireless communications provider licensed by the Federal Communications Commission and registered with the Hawai'i Public Utilities Commission. Voiees-tream is currently developing a wireless communication network in the County of Hawai'i using stealth antennas.
The instant case concerns the proposed installation of a stealth antenna at the residence of Timothy and LeNora Wee in the Pu'u Nani Agricultural Subdivision in Ka-muela, Hawai'i. Voicestream planned to attach to the Wee residence a false chimney housing a 23.5-foot tall pole, measuring 2 and 7/8 inches in diameter, with three flat-panel directional antennas momited flush with the top of the pole. Voicestream’s plan also includes the construction of a separate garage to house equipment for the antenna.
B. Procedural Background
Prior to August 31, 2000, Voicestream informally requested that the County of Ha-wai'i Planning Director (planning director) determine whether a special permit was required for the proposed stealth antenna.3 After consulting with the Department of the Corporation Counsel, the planning director informed Voicestream that a special permit was required for all telecommunications antennas pursuant to this court’s decision in Curtis v. Bd. of Appeals, County of Hawai‘i, 90 Hawai'i 384, 394-97, 978 P.2d 822, 832-35 (1999), wherein this court held that a special permit was required to build a 140-foot cellular telephone tower on state agricultural land.
On August 31, 2000, Voicestream filed its application for a special permit for the proposed stealth antenna. A hearing on the special permit application was held on October 20, 2000, during which Voicestream requested that the HCPC make a preliminary decision pursuant to HRS § 91-8 (1993)4 as to whether a special permit was required before rendering a decision on the special permit application. The HCPC unanimously decided that the stealth antenna required a special permit and granted the issuance thereof. On November 24, 2000, the HCPC entered its written decision.
On December 15, 2000, Voicestream appealed to the circuit court, seeking review of the HCPC’s decision that a special permit was required for its stealth antenna.5 Voi-cestream contended that this court’s decision in Curtis did not require it to obtain a special permit pursuant to HRS §§ 205-4.5 (Supp. 1997), quoted infra> and 205-6(a) (Supp. 1998)6 to construct and maintain the proposed stealth antenna in the state land use agricultural district. After a hearing on the matter, the circuit court affirmed the decision of the HCPC on June 18, 2001 and entered the following findings of fact (FOF) and conclusions of law (COL):
FINDINGS OF FACT
1. The HCPC has agreed that the statement of facts in VoiceStream’s Opening Brief filed on January 31, 2001, pp. 2-5, is accurate and therefore the [c]ourt [346]*346accepts these facts as proven and incorporates them herein by reference.
2. The wireless communications antennae [sic] proposed by VoiceStream would be enclosed in a false chimney constructed by VoiceStream and which would be incorporated into the Wee residence. The communication equipment associated with the antennae would be locked in a cabinet that would be at the rear of a new garage that VoiceStream would construct.
3. The height of the antennae [sic], 23.5 feet, would be within the height limitations for farm dwellings in the State land use and County zoning districts.
4. Both the garage and the chimney are permitted uses as accessory to a farm dwelling 'pursuant to HRS Ch. 205 and Hawaii County Code Ch. 25.
5. The HCPC’s interpretation of Curtis as stated in its Decision and in the statements of [the planning director] is that a Special Permit is required to construct or maintain any cellular communication “tower” or “antenna.”
6. The court accepts as fact that Voi-ceStream intends to continue building “stealth” or concealed cellular communications antennae in Hawaii County state land use Agricultural District.
7. The court accepts as fact that the HCPC’s position will continue to be that an HRS § 205-6 Special Permit is required for each and every case in which VoieeS-tream intends to construct any cellular communications antenna in a Hawaii County state land use Agricultural District.
CONCLUSIONS OF LAW
1. This court has jurisdiction over this appeal pursuant to HRS §§ 603-21.8, and 91-7.
2. The ongoing adverse interest to Voi-ceStream is the HCPC’s interpretation of Curtis: that the construction of a wireless communications antenna, even under the circumstances presented here where the antenna will be completely enclosed within an otherwise legally permitted structure, requires a Special Permit issued pursuant to HRS § 205-6.
3. This court can fashion an effective remedy by deciding whether or not an HRS § 205-6 Special Permit is in fact required in this ease.
4. Accordingly, the Appeal is not moot and this court has jurisdiction to decide the merits of the Appeal because there is an adverse impact and the court can provide an effective remedy to VoiceStream.
5. However, this court finds that in Curtis the Hawaii Supreme Court interpreted the exceptions listed in HRS § 205-4.5 to exclude the construction of cellular communication towers by its holding: “[w]e therefore hold that the terms ‘communications equipment building’ and ‘utility lines’ as employed in HRS § 205-1.5(7) cannot encompass ‘telecommunications antennas’ or ‘transmission antennas’ such as the instant cellular phone tower.”
6. The court finds that based on the Curtis analysis, VoiceStream’s cellular communication antenna enclosed within a chimney does not fall within the definition of a “communications equipment building” as provided in HRS § 205-k-5(a)(7).
7. The court also finds that the cellular communication antenna enclosed within a chimney is not a building or use that is normally considered accessory to a permitted farm dwelling, employee housing, or farm building as provided in HRS § 205-L5(a)(I) and-L5(a)(10).
(Emphases added.) (Citations omitted.) On July 5, 2001, pursuant to HRS § 602-5(1) (1993) and Hawai'i Rules of Appellate Procedure Rule 3 (2000) and Rule 4 (2001), VoiceS-tream filed its timely notice of appeal to this court.
II. STANDARDS OF REVIEW
A. Review of an Agency Decision
Review of a decision made by the circuit court upon its review of an agency’s decision is a secondary appeal. The standard of review is one in which this court must determine whether the circuit court was right or wrong in its decision, applying the standards set forth in HRS § 91-14(g) to the agency’s decision.
[347]*347HRS § 91-14 [ (1993) ], entitled “Judicial review of contested cases,” provides in relevant part:
(g) Upon review of the record the court may affirm the decision of the agency or remand the case with instructions for further proceedings; or it may reverse or modify the decision and order if the substantial rights of the petitioners may have been prejudiced because the administrative findings, conclusions, decisions, or orders are:
(1) In violation of constitutional or statutory provisions; or
(2) In excess of the statutory authority or jurisdiction of the agency; or
(3) Made upon unlawful procedure; or
(4) Affected by other error of law; or
(5) Clearly erroneous in view of the reliable, probative, and substantial evidence on the whole record; or
(6) Arbitrary, or capricious, or characterized by abuse of discretion or clearly unwarranted exercise of discretion.
[Ujnder HRS § 91 — 14(g), conclusions of law are reviewable under subsections (1), (2) and (4); questions regarding procedural defects under subsection (3); findings of fact under subsection (5); and an agency’s exercise of discretion under subsection (6).
Paul’s Electrical Service, Inc. v. Befitel, 104 Hawai'i 412, 416, 91 P.3d 494, 498 (2004) (citations and quotation marks omitted). “Pursuant to HRS § -91-14(g), an agency’s conclusions of law are reviewed de novo.” Id. at 420, 91 P.3d at 502 (citing Camara v. Agsalud, 67 Haw. 212, 216, 685 P.2d 794, 797 (1984)).
B. Statutory Interpretation
“The interpretation of a statute ... is a question of law reviewable de novo.”
Furthermore, our statutory construction is guided by established rules:
When construing a statute, our foremost obligation is to ascertain and give effect to the intention of the legislature, which is to be obtained primarily from the language contained in the statute itself. And we must read statutory language in the context of the entire statute and construe it in a manner consistent with its purpose.
When there is doubt, doubleness of meaning, or indistinetiveness or uncertainty of an expression used in a statute, an ambiguity exists....
In construing an ambiguous statute, “the meaning of the ambiguous words may be sought by examining the context, with which the ambiguous words, phrases, and sentences may be compared, in order to ascertain their true meaning.” Moreover, the courts may resort to extrinsic aids in determining legislative intent. One avenue is the use of legislative history as an interpretive tool.
This court may also consider “the reason and spirit of the law, and the cause which induced the legislature to enact it ... to discover its true meaning.” “Laws in pari materia, or upon the same subject matter, shall be construed with reference to each other. What is clear in one statute may be called upon in aid to explain what is doubtful in another.”
Barnett v. State, 91 Hawai'i 20, 31, 979 P.2d 1046, 1057 (1999) (ellipses points in original) (citations and brackets omitted).
III. DISCUSSION
As indicated above, the circuit court concluded that:
the cellular communication antenna enclosed within a chimney is not a building or use that is normally considered accessory to a permitted farm dwelling, employee housing, or fam building as provided in HRS § 205-4.5(a)(4) and - 4.5(a)(10).
COL No. 7 (emphasis added). HRS § 205-4.5(a) states in relevant part:
Permissible uses within the agricultural districts.
(a) Within the agricultural district all lands with soil classified by the land study bureau’s detailed land classification as overall (master) productivity rating class A [348]*348or B[7] shall be restricted to the following permitted uses:
[[Image here]]
(4) Farm dwellings, employee housing, farm buildings, or activity or uses related to farming and animal husbandry;
Farm dwelling as used in this paragraph means a single-family dwelling located on and used in connection with a farm, including clusters of single-family farm dwellings permitted within agricultural parks developed by the State, or where agricultural activity provides income to the family occupying the dwelling;
[[Image here]]
(10) Buildings and uses, including but not limited to mills, storage, and processing facilities, maintenance facilities, and vehicle and equipment storage areas that are normally considered directly accessory to the abovementioned uses [(ie., in this case, farming and animal husbandry) ] and are permitted under section 205-2(d)[ (Supp.1995).8]
(Emphases added.)
The circuit court also concluded that:
based on the Cuvtis analysis, VoiceS-tream’s cellular communication antenna enclosed within a chimney does not fall within the definition of a “communications equipment building” as provided in HRS S 205-4.5(a)(7).
COL No. 6 (emphasis added). Permitted uses under HRS § 205^4.5(a)(7) include:
Public, private, and quasi-public utility lines and roadways, transformer stations, communications equipment buildings, solid waste transfer stations, major water storage tanks, and appurtenant small buildings such as booster pumping stations, but not including offices or yards for equipment, material, vehicle storage, repair or maintenance, or treatment plants, or corporation yards, or other like structures^]
(Emphasis added.)
In Curtis, the USCOC of Hawai'i 8, Inc. (U.S. Cellular), a certified public utility, constructed a 140-foot cellular telephone tower, which sits on a concrete foundation, in South Kona, as well as a small prefabricated building containing communications equipment situated next to the tower. 90 Hawai'i at 387, 978 P.2d at 825. “Photographs reveal that the tower stands well over twice the height of any of the surrounding vegetation and structures.” Id. The tower and prefabricated building were constructed pursuant to a special management area minor permit is[349]*349sued by the Hawai'i County planning department. Id.
Surrounding neighbors of the communications tower challenged the planning director’s approval of the construction, which was rejected by the Hawai'i County Board of Appeals. Id. The circuit court, on appeal, reversed the board’s decision, ruling, inter alia, that the tower was not a permitted use in an agricultural district. On appeal to this court, U.S. Cellular and the County of Ha-wai'i argued that “the tower in question is a permitted use ‘as of right’ in an agricultural district as a ‘utility line’ or ‘communications equipment building’ under section 205-4.5(a)(7).” Id. at 394-95, 978 P.2d at 832-33. Relying on the plain language of the statute1 to conclude that the tower was not a “communications equipment building,” this court stated:
Preliminarily, we agree that the plain meaning of “communications equipment buildings” excludes cellular telephone towers. Black’s Law Dictionary (6th ed.1990) defines “building”' as a “[structure designed for habitation, shelter, storage.... A structure or edifice enclosing a space within its walls[.]” The term “communications equipment building, ” therefore, denotes a structure — not unlike the small prefabricated building accompanying the toiver in the instant case — containing or housing communications equipment, rather than standing as a gigantic piece of such equipment in itself. At the outset, therefore, we hold that “communications equipment buildings” does not include cellular telephone towers.
Id. at 395, 978 P.2d at 833 (emphasis added) (citation omitted) (ellipses points and brackets in original).
With respect to whether the tower fell within the term “utility lines” as employed in HRS § 205^1.5(a)(7), this court observed that “[tjhe meaning of ‘utility lines,’ however, is not so clear.” Id. This court, therefore, turned to the “reason and spirit” of the state land use law to determine whether the tower fell within what the legislature contemplated as utility lines.” Id. at 396, 978 P.2d at 834. We recognized that the stated purpose of land use law is, inter alia,
to protect and conserve through zoning the urban, agricultural and conservation lands within all the counties.
A coordinated, balanced approach not only within each county but an overall balance of statewide land needs for economic growth is essential to:
(1) Utilize the land resources in an intelligent, effective manner based upon the capabilities and characteristics of the soil and the needs of the economy;
(2) Conserve forests, water resources and land, particularly to preserve the prime agricultural lands from unnecessary urbanization;
(3) State the allocation of land for development in an orderly plan to meet actual needs and minimize costs of providing utilities and other public services....
Id. (citing Hse. Stand. Comm. Rep. No. 395, in 1961 House Journal, at 855-56) (emphases and footnote omitted). Based on the “reason and spirit” of land use law, we held that “the wholesale inclusion of cellular telephone towers in agricultural districts as ‘utility lines’ under HRS § 205-4.5(a)(7) unreasonably expands the intended scope of this term and frustrates the- state land use law’s basic objectives of protection and rational development.” Id. at 396, 978 P.2d at 834.
In reaching the foregoing conclusion, we distinguished the tower from recognized public utilities in Hawai'i County. Id. at 395-96, 978 P.2d at 833-34. Specifically, we referenced Public Utilities Commission, General Order No. 6 Rule 21.7 (rev.1969), which set forth the spatial limitations for overhead electric lines. Id. at 395 n. 14, 978 P.2d at 833 n. 14. Because the minimum vertical clearance of electrical wires, a recognized utility, was fifteen to thirty feet, we held that the tower in Cwitis was disproportionately larger and represented “a material departure from garden variety utility poles generally a fraction of the tower’s size.”9 Id. at 396, 978 P.2d at 834 (footnote omitted).
[350]*350Moreover, we noted the controversy in other jurisdictions surrounding the recent emergence of telecommunications antennas to demonstrate that, notwithstanding their “functional” similarity to “utility lines,” telecommunications antenna towers are distinguishable therefrom because their size tends to strain the limits of land use convention and practice. Id. at 397, 978 P.2d at 835 (citing Evans v. Shore Communications, Inc., 112 Md.App. 284, 685 A.2d 454, 462 (Md.1996) (addressing zoning board’s conclusion that variance to increase 200-foot tower to 300-feet would result in loss of scenic views); Smart SMR v. Borough of Fair Lawn Bd. of Adjustment, 152 N.J. 309, 704 A.2d 1271, 1274, 1277 (1998) (illustrating zoning board’s decision that 140-foot “monopole” would be aesthetically displeasing); Crown Communications v. Zoning Hearing Bd. of Borough of Glenfield, 550 Pa. 266, 705 A.2d 427, 430 (1997) (describing zoning board’s decision that 375-foot communications tower would be a nuisance); Westel-Milwaukee Co. v. Walworth County, 205 Wis.2d 244, 556 N.W.2d 107, 108 (Wis.Ct.App.1996) (entertaining claims that 200-foot telecommunications tower would depreciate the value of surrounding property and negatively impact the aesthetics of scenic farmland)). ■
Based on the foregoing analysis, we held that
the terms “communications equipment building” and “utility lines,” as employed in HRS § 205^.5[ (a) ](7) do not encompass “telecommunications antennas” or “transmission antennas” such as the instant cellular telephone tower. U.S. Cellular must therefore apply for a special permit under HRS § 205-6 to place the tower in a state agricultural district.
Curtis, 90 Hawai'i at 397, 978 P.2d at 835.
In the instant appeal, Voieestream contends that the circuit court erred by concluding that, based on Curtis: (1) the antenna is not a building or use that is normally considered accessory to a permitted farm dwelling, employee housing, or farm building, pursuant to HRS §§ 205-4.5(a)(4) and -4.5(a)(10); (2) Voicestream’s cellular antenna, concealed within a false chimney, does not fall within the definition of a “communications equipment building” as provided in HRS § 205-4.5(a)(7); and (3) a special permit was required for Voieestream to construct its cellular antenna inside a false chimney that, standing alone, would be a permitted use in the state land use agricultural district and under county zoning.10 In essence, Voices-tream seeks a determination whether its proposed construction is a “permitted use” in the state land use agricultural district under HRS § 205-4.5(a). In making that determination, we examine, as did the HCPC and the circuit court, whether Voicestream’s proposed construction is permitted: (1) as a building or use directly accessory to a farm dwelling under HRS §§ 205-4.5(a)(4) and - 4.5(a)(10); and/or (2) as a “communications equipment building” under HRS § 205-4.5(a)(7).
A. Whether Voicestream’s Proposed Con-stmetion is Permitted as a Building or Use Directly Accessory to a Fatrm Dwelling under HRS §§ 205-j.5(a)(j) and -L 5 (a) (10)
As previously indicated, Voices-tream’s proposed construction involves the placement of a chimney on the Wee residence to house the cellular antenna, as well as building a separate garage to house equipment for the antenna. The circuit court’s unchallenged FOF Nos. 3 and 4 establish, respectively, that (1) the height of the antenna (23.5 feet) is within the height limitations for farm dwellings in the state land use and county zoning districts and (2) the chimney and garage, by themselves, are permitted as [351]*351accessory to a farm dwelling. Concealing the cellular antenna within the permitted chimney and housing equipment for the antenna in the permitted garage, however, require further examination.
Pursuant to HRS §§ 205-4.5(a)(4) and - 4.5(a)(10), buildings and uses or activities related to fanning and animal husbandry, including those considered directly accessory to such uses, are permissible. Clearly, a wireless communications antenna and its attendant equipment are not uses related to farming and animal husbandry.
We, therefore, hold that, under HRS §§ 205-15(a)(4) and -4.5(a)(10), the chimney and garage themselves are permitted as accessory to a farm dwelling; however, utilizing the chimney to conceal the antenna and the garage to house the communication equipment are not permitted uses under either subsection (a)(4) or (a)(10) of the statute.
B. Whether Voicestream’s Proposed Construction is Permitted as a “Communications Equipment Building” under HRS § 205-b.5(a)(7)
As previously indicated, Voicestream argues that the circuit court erred in concluding that its cellular antenna, concealed within a false chimney, does not fall within the definition of a “communications equipment building” as provided in HRS § 205-4.5(a)(7).
In Curtis, this court relied on the plain language of HRS § 205-4.5(a)(7) to hold that the cellular telephone tower at issue therein did not constitute a “communications equipment building” inasmuch as it was not a “‘structure designed for habitation, shelter, [or] storage ... [and was not a] structure or edifice enclosing a space within its walls.’” Curtis, 90 Hawai'i at 395, 978 P.2d at 833 (brackets in original omitted). However, in our view, the chimney in the instant case qualifies as a “building” as defined in Curtis because it is a “structure designed for ... storage” (i.e., the antenna) and is also a “structure or edifice enclosing a space within its walls.” Id. Additionally, the Wee residence is a “building” as defined in Curtis because it is a “structure designed for habitation, shelter ... [and is a] structure or edifice enclosing a space within its walls.” Id. (brackets omitted).
It is undisputed that the cellular antenna in this case, like the cellular telephone tower in Curtis, including its accompanying equipment, are communications equipment. Thus, we hold that, under the circumstances of this case, the Wee residence and the chimney with the concealed antenna constitute a “communications equipment building” and, thus, are permitted uses under HRS § 205-4.5(a)(7). •
With respect to Voicestream’s plan to build a garage to house equipment for the antenna, such a garage would be similar to the prefabricated building that this court approved of in Curtis. See Curtis, 90 Hawai'i at 395, 978 P.2d at 833 (holding that “[t]he term ‘communications equipment building,’ therefore, denotes a structure — not unlike the small prefabricated building accompanying the tower in the instant ease — containing or housing communications equipment”). As in Cmiis, the garage in the instant ease is not abnormally large and was designed specifically to store the communications equipment for Voi-eestream’s concealed antenna. Thus, consistent with our decision in Curtis, we hold that utilizing the permitted garage structure to house the communications equipment for the antenna is a permitted use under HRS § 205-4.5(a)(7).
The dissent asserts that our analysis would enable wireless service providers to circumvent the permitting process by simply enclosing large antennas within four walls. According to the dissent, since a “communications equipment building” is not limited by any height restrictions under HRS § 205-4.5(a)(7), wireless service providers could construct large antennas without obtaining a special permit by (1) enclosing them so as to be permissible under HRS § 205-4.5(a)(7) as “communications equipment buildings” and then (2) labeling the antennas and their enclosures “telecommunications antennas”11 under HOC § 25-l-5(B)(101), which are allowed as of right, HCC § 25-5-71(a)(21), up [352]*352to a height of five hundred feet, HCC § 25-4-22(c), on agricultural land. See dissent at 354-56, 104 P.3d at 941-942. We disagree.
As previously discussed, an enclosed antenna constitutes a “communications equipment building” under HRS § 205^4.5(a)(7). Under county zoning ordinances, however, an enclosed antenna is a building, not a “telecommunications antenna.” HCC § 25-1-5(b)(15) defines “building” as “any structure used or intended for support or sheltering any use or occupancy.” Inasmuch as the enclosure for the antenna is intended to support wireless transmissions and/or shelter communications equipment, it is a “building.”
HCC § 25 — 1—5(b)( 101) defines a “telecommunications antenna” as an “antenna, tower and other accessory structures for radio frequency (RF) transmissions intended for specific users who must have special equipment for transmission and/or reception.” (Emphasis .added.) In order' for the enclosed antenna and its surrounding structure (i.e., building) to fall within the definition of a “telecommunications antenna,” the building must be an “accessory structure.”
The term “accessory structure” is not defined by the HCC. However, we recognize that, in statutory construction, “laws in paid materia, or upon the same subject matter, shall be construed with reference to each other. What is clear in one statute may be called upon in aid to explain what is doubtful in another.” Barnett, 91 Hawai'i at 31, 979 P.2d at 1057. HCC § 25-l-5(b)(99) provides that the term “structure” includes the term “building.” Thus, inasmuch as the term “structure” encompasses a “building,” it logically follows that an “accessory structure” encompasses an “accessory building.” HCC § 25 — 1—5(b)(1) defines an “accessory building” as a “building, no more than twenty feet in height, detached from and subordinate to a. main building or main use on the same building site and used for the purposes customarily incidental to those of the main building or use.” (Emphasis added.) Clearly, a building enclosing an antenna is not detached from a main building or use since it, in effect, is the main building. Consequently, a building enclosing an antenna cannot be an “accessory building” under HCC § 25-1-5(b)(1). Thus, an enclosed antenna does not fall within the definition of a “telecommunications antenna” under HCC § 25-l-5(b)(101).
We reiterate, however, that an enclosed antenna is still a building and, therefore, subject to the height limitations prescribed in HCC §§ 25-5-7312 and 25-4-2213 (1999).
The dissent also contends that the structures in the instant ease are not “communications equipment buildings” because they are inconsistent with the legislative history regarding HRS § 205-4.5(a)(7). See dissent at 356-58, 104 P.3d at 942-944. It is well-settled in this jurisdiction that courts turn to legislative history as an interpretive tool only where a statute is unclear or ambiguous. State v. Mueller, 102 Hawai'i 391, 394, 76 P.3d 943, 946 (2003). In Mueller, this court held:
A cardinal canon of statutory construction is that this court cannot change the language of the statute, supply a want, or enlarge upon it in order to make it suit a certain state of facts. This is because we do not legislate or make laws. It is a cardinal rule of statutory interpretation that, where the terms of a statute are plain, unambiguous and explicit, we are not at liberty to look beyond that language for a different meaning. Instead, our sole [353]*353duty is to give effect to the statute’s plain and obvious meaning.
Id. (citations, quotation marks and brackets omitted) (emphasis added). Given the foregoing, we note that in Curtis, this court held that a 140-foot tower was not a permitted use in an agricultural district based on the plain meaning of “communications equipment building.” 90 Hawai'i at 395, 978 P.2d at 833. Thus, inasmuch as this court has previously recognized the term “communications equipment building” as utilized in HRS § 205-4.5(a)(7) to be plain and unambiguous, we are not at liberty to look beyond the statute’s plain and obvious meaning.
Nevertheless, even if this court were to examine legislative history as an interpretive tool, the structures in the instant case — to wit, the Wee residence with the false chimney housing Voicestream’s antenna and the garage housing the accompanying equipment — are consistent with the legislature’s intent.
The House standing committee report addressing the addition of “communications equipment building” to HRS § 205-4.5(a)(7) stated:
The purpose of this bill is to include communications equipment buildings as a permitted use in agricultural land along with other similar utilities now permitted.
This bill will permit Hawaiian Telephone to construct such facilities as other public service companies and agencies are now permitted without the need to apply for variances. It will also enable the customers to receive telephone service much faster than the present time-consuming method.
Hse. Stand. Comm. Rep. No. 690, in 1977 House Journal, at 1605. Further, the Senate standing committee report commented that the addition of “communications equipment buildings” to HRS § 205-4.5(a)(7)
would improve service to telephone customers and reduce the cost of providing service. Other utilities are [now] permitted in agricultural land, such as utility lines, electric transformer stations and water booster pumping stations; this bill will include communications equipment buildings as well and will better serve farmers and others residing in agricultural lands.
Sen. Stand. Comm. Rep. No. 840, in 1977 Senate Journal, at 1219 (emphasis added). The dissent argues that Voicestream’s construction was not intended by the legislature to be included in the term “communications equipment building” because “the additional ‘communications equipment’ then needed to complete the agricultural district’s wire-based networks [are] certainly not comparable in function, much less scale, to the transmitting towers and antennas now required to send wireless telephone signals into far flung agricultural areas.” See dissent at 357, 104 P.3d at 943. With respect to function, we fail to see any function specific to the communications equipment required for land lines that would distinguish such equipment from that needed to support wireless transmissions. Both appear to serve the same purpose, mainly, to facilitate telephone communications.
Moreover, the dissent makes no argument that the function of Voicestream’s wireless communications equipment is inconsistent with the legislature’s intent to “better serve farmers and others residing in agricultural lands.” Voicestream’s structures are intended to facilitate a transmission link from Wai-mea to the highway leading to Honoka'a inasmuch as current service in the Wai-mea/Kamuela area covers only the immediate town. Thus, by allowing Voicestream to erect its structures, Voicestream would be able to provide wireless coverage for farmers and others residing in agricultural lands who are currently without access. We believe this service is consistent with the legislature’s intent.
With respect to scale, the dissent’s bald assertion that the equipment necessary for wireless telephone signals is larger in scale than that required for land lines in 1977— when the term “communications equipment building” was added to HRS § 205-4.5(a)(7) — lacks merit. There is no evidence in the record — and the dissent points to nothing in the record or elsewhere — to support its assertion. What the record reflects is the fact that the communications equipment for Voicestream’s wireless signal would be [354]*354housed in a false chimney and within a locker in the back of a permitted garage structure. We believe the scale for the communications equipment, under the instant facts, is not substantial. Accordingly, inasmuch as the equipment for land lines and wireless signals are “comparable” in function and scale, our holdings that Voieestream’s structures are “communications equipment buildings” are consistent with the legislature’s intent.
Moreover, we believe that our holdings today are consonant with legislative intent in that they also comport with the “reason and spirit” of state land use law. Unlike the 140-foot tower in Curtis, or the other massive antenna towers referenced in the cases cited therein, the antenna in this case is entirely concealed within a chimney that, standing alone, is permitted under HRS §§ 205-4.5(a)(4) and -4.5(a)(10) and is clearly not “standing as a gigantic piece of ... equipment in itself.” Curtis, 90 Hawai'i at 395, 978 P.2d at 833. Additionally, contrary to the dissent’s view, there is nothing in the record to indicate that the presence of the concealed antenna in this case would undermine the state land use law’s objectives of protecting and conserving natural resources and fostering intelligent, effective, and orderly land allocation and development, or expand the intended scope of the term “communications equipment building.” Curtis, 90 Hawai'i at 396, 978 P.2d at 834.
III. CONCLUSION
Based on the foregoing, we hold that: (1) under HRS §§ 205-4.5(a)(4) and -4.5(a)(10), the chimney and garage themselves are permitted as accessory to a farm dwelling; however, utilizing the chimney to conceal the antenna and the garage to house the communication equipment are not permitted uses under either subsection (a)(4) or (a)(10) of the statute; (2) under the circumstances of this case, the Wee residence and the chimney with the concealed antenna constitute a “communications equipment building” and, thus, are permitted uses under HRS § 205-4.5(a)(7); and (3) utilizing the permitted garage structure to house the communication equipment for the antenna is a permitted use under HRS § 205-4.5(a)(7). Consequently, Voicestream is not required to obtain a special permit for the proposed installation that is the subject of this appeal (i.e., construction of a false chimney to conceal its 23.5-foot cellular antenna and a garage to house its communications equipment). Accordingly, we reverse the circuit court’s June 18, 2001 judgment affirming the decision of the HCPC.
