NOTICE: Summary decisions issued by the Appeals Court pursuant to M.A.C. Rule 23.0, as appearing in 97 Mass. App. Ct. 1017 (2020) (formerly known as rule 1:28, as amended by 73 Mass. App. Ct. 1001 [2009]), are primarily directed to the parties and, therefore, may not fully address the facts of the case or the panel's decisional rationale. Moreover, such decisions are not circulated to the entire court and, therefore, represent only the views of the panel that decided the case. A summary decision pursuant to rule 23.0 or rule 1:28 issued after February 25, 2008, may be cited for its persuasive value but, because of the limitations noted above, not as binding precedent. See Chace v. Curran, 71 Mass. App. Ct. 258, 260 n.4 (2008).

RAHAB KIAMBUTHI & another1

vs.

GEORGE MUMO.

MEMORANDUM AND ORDER PURSUANT TO RULE 23.0

The defendant, George Mumo (tenant), appeals from a

judgment entered in the Housing Court following a bench trial

that awarded damages, fees, and costs to the plaintiffs, Rahab

Kiambuthi and David Ikanyi (landlords). In a detailed written

decision, the judge determined that the tenant owed $3,600 to

the landlords in unpaid rent or use and occupancy fees, but also

that the tenant was entitled to damages of $1,244. The judge

determined that the tenant proved his counterclaim alleging

breaches of the warranty of habitability because of the presence

of bedbugs for four months and absence of a stair rail for the

whole tenancy, and he applied five and 0.5 percent diminutions

of value to calculate the tenant's damages for these breaches. To avoid duplication, however, the damages for the missing stair rail were awarded under G. L. c. 93A instead of the warranty of habitability, and then doubled, because the judge found that persistent defect also to be a knowing violation of the statute. The judge further found that the landlords failed to maintain security deposit funds properly, in violation of the security deposit law, G. L. c. 186, § 15B, as then in effect2; and that the tenant did not prove the remainder of his counterclaims. Offsetting the unpaid rent against the counterclaim damages, the judge concluded that the tenant owed the landlords a balance of $2,356. Judgment for damages in that amount (plus court costs, fees, and interest) entered for the landlords, and the tenant appealed.

On appeal, the tenant contends that the judge erred in (1) admitting the lease as evidence and finding that it required the tenant to pay for electricity and gas utility charges; (2) finding that the tenant owed two months of rent; (3) determining the amount of damages on the tenant's warranty of habitability claim; (4) denying relief on the tenant's counterclaim alleging interference with quiet enjoyment; (5) concluding that the tenant did not prove retaliation; and

(6) calculating the amount owed to the tenant under the security deposit law. We affirm.

1. Standard of review. In reviewing the judge's decision, "'we accept [the judge's] findings of fact as true unless they are clearly erroneous,' but 'we scrutinize without deference the legal standard which the judge applied to the facts.'" Cambridge St. Realty, LLC v. Stewart, 481 Mass. 121, 123 (2018), quoting Andover Hous. Auth. v. Shkolnik, 443 Mass. 300, 306 (2005). See Kelly v. Jones, 80 Mass. App. Ct. 476, 478 (2011) (deference given to trial judge's credibility determinations).

2. Discussion. a. Admission of lease. The tenant first argues that the judge abused his discretion admitting in evidence, crediting the terms of, and applying the terms of the unsigned lease offered by the landlords as an exhibit. We are not persuaded.

The trial judge credited the landlords' trial testimony that they provided the tenant with a standard form lease. The tenant promised to sign and return the lease, but did not do so. The tenant subsequently took possession of the premises and began paying monthly rent.

At trial, the landlords submitted a form lease as an exhibit, which they contended was an accurate representation of the lease provided to the tenant. The tenant objected to the lease's admission in evidence. The judge found that the terms

of the lease applied on the basis of promissory estoppel, because in allowing the tenant to move into the premises, the landlords relied on the tenant's representations that he would return a signed copy of the lease, and the tenant in fact began to pay monthly rent in the amount of $1,800 per month after he moved in. See Loranger Const. Corp. v. E.F. Hauserman Co., 6 Mass. App. Ct. 152, 154-159 (1978), S.C., 376 Mass. 757 (1978). The judge further found that the tenant acknowledged the original lease by submitting in evidence at trial a one-page lease addendum that refers to it. The addendum is dated January 30, 2021, acknowledges a twelve-page lease (the lease is twelve pages if including the apartment condition statement and not the lead paint disclosure), notes the rent total of $1,800, and is signed by one of the landlords. The application of equitable estoppel principles is a matter of discretion, Otis v. Arbella Mut. Ins. Co., 443 Mass. 634, 640 (2005), and the judge did not abuse his discretion in admitting the lease in evidence. See L.L. v. Commonwealth, 470 Mass. 169, 185 n.27 (2014).

Relatedly, the tenant argues that the judge erred in relying on the lease to find that the tenant was responsible for utilities, thus rejecting his claim of reimbursement for electricity and gas utility charges. The tenant points to the fact that, at one point during trial, the judge apparently mistakenly stated that the lease did not charge the tenant for

electricity. In fact, as the judge explained in his decision, the lease states that the tenant will pay for all utilities except water and garbage pickup, which is to be handled by the landlords. Accordingly, the judge did not err in finding that the tenant's claims for reimbursement of electricity and gas utility charges were not supported.

b. Awarding March 2024 rent. The tenant argues that the judge should not have awarded the landlords the entirety of March 2024 rent, but only a prorated amount, because the tenant moved out on March 4, 2024. In concluding that the tenant was liable for the March 2024 rent, the judge found that, even though the tenant moved out on March 4, 2024, the landlords did not know in advance that this was the date certain on which he would vacate. The judge further found that rent was due on the first of each month and, even though the tenant occupied the unit on March 1, 2024, he did not pay the landlords rent for that month. The judge's conclusion that the tenant was liable for the March 2024 rent was not clearly erroneous, particularly where he offset the amount by the tenant's damages.

c. Damages for breaches of warranty of habitability. The judge found two breaches of the implied warranty of habitability. First, there was a breach because of active bedbugs from September 2021 until they were eradicated by exterminators in December 2021, a period for which the judge

reduced the value of the rental by five percent, equaling damages for the tenant of $360. Second, there was a breach because of a missing hand rail along the stairs to the basement, for which the judge reduced the value of the rental by 0.5 percent for thirty-eight months, totaling damages of $342. The tenant now argues that the judge's diminution in value as a result of the bedbugs should have accounted for eleven months, not four, because the bedbugs were present when he moved into the premises. Additionally, the tenant argues that the judge's diminution of 0.5 percent because of the stair rail was insufficient. We disagree.
