Opinion

San Francisco Division TIMOTHY R PEDEN, et al., Case No. 26-cv-00013-LB

Plaintiffs, ORDER GRANTING IN PART AND DENYING IN PART MOTION TO v. DISMISS

MARK WHITNEY, et al., Re: ECF No. 56 Defendants. Plaintiffs Patricia and Timothy Peden hired defendant Mark Whitney to build a retaining wall at their hillside home in Guerneville, California. On December 3, 2025, the Pedens terminated Whitney’s services and then sued him for his allegedly wrongful conduct.1 Whitney counterclaimed for (1) breach of the parties’ written contract, (2) breach of the implied covenant of good faith and fair dealing, (3) a common count for the reasonable value of services and materials, and (4) declaratory relief that Whitney and his subcontractors are relieved of any warranty or liability.2

1 Compl. – ECF No. 1; Am. Compl. – ECF No. 51 (adding Whitney Homes, Inc., and Platte River Insurance Company as defendants). Citations refer to material in the Electronic Case File (ECF); pinpoint citations are to the ECF-generated page numbers at the top of documents. The Pedens moved under Federal Rule of Civil Procedure 12(b)(6) to dismiss claims two through four, generally on the ground that they duplicate claim one for breach of contract.3 The motion is granted in part and denied in part. Claim two for breach of the implied covenant is dismissed with leave to amend: it rests on the same allegedly bad acts and seeks the same $43,946.72 as the contract claim, and it thus is superfluous. Claim three, predicated on reasonable- value and unjust-enrichment theories, survives in part: the Pedens dispute in their complaint whether there is a valid written contract, and Whitney may plead a claim in quasi-contract as an alternative to the contract claim. Claim four for declaratory relief is dismissed: Whitney lacks standing for third-party contractors and his duties and liabilities will be determined by the adjudication of the negligence claims. The Pedens own a hillside home in Guerneville, Sonoma County. In 2023, they retained Whitney, a general contractor, to design a retaining wall and obtain a County building permit.4 In March 2024, after a building permit was issued, Whitney offered to build the retaining wall for $150,000, presenting the offer on a statutory home-improvement contract form.5 The Pedens — through counsel — reviewed the offer and proposed changes to the form contract, including disclosures that they believed were required.6 The Pedens did not accept the contract at that time (March 2024).7 The Pedens looked for another contractor, did not find one, and returned to Whitney.8 In February 2025, Whitney provided the Pedens with a simplified written proposal (the “Construction Agreement”), which provided that Whitney would, for a fixed cost of $175,200, [s]upply all labor, materials & equipment to build a retaining wall per approved plans, to include the following:

3 Mot. – ECF No. 56. 4 Countercls. – ECF No. 48 at 2–3 (¶¶ 1–7, 9, 14–16); Construction Agreement, Ex. 3 to id. at 26. 5 Countercls. – ECF No. 48 at 4–5 (¶¶ 21–25); Home-Improvement Contract, Ex. 2 to id. at 20. 6 Countercls. – ECF No. 48 at 5 (¶¶ 26–29) (Ms. Peden, an attorney, also reviewed the contract). 7 Id. at 5 (¶ 30). Clear off, mark out, cut back hill side, clear out and excavate for new wall & post base footings, haul off included . . . Set up footings & wall approx. 68’ long with various widths per details on S3 . . . All rebar installation will be inspected prior to concrete pour . . . All necessary clean up work . . . . “All other work will be at an additional cost approved by owner & contractor prior to proceeding.”9 The Pedens signed the agreement on March 1, 2025.10 Additional work allegedly proceeded by change orders, including Change Order #15 for $30,308 for additional work identified by a project engineer, who (after excavation) determined that the hillside was weaker than the soils report had suggested and recommended adding eighteen concrete piers.11 The Pedens declined other change orders, such as a geotechnical change order in November 2025 for added work, electing to proceed with the work directly.12 On December 2, 2025, before the pier drilling began but after Whitney had built the rebar cages and laid half of the pier locations, the Pedens sent an email to Whitney to stop working on the project. The next day, they sent an email terminating the contract.13 Before and after December 3, Whitney wrote to the Pedens, warning them that it was not prudent to stop work during wet weather, given the recommendation of adding the piers.14 In February 2026, the Pedens allegedly “experienced adverse impacts at their property at the cut hillside” from heavy and regular rains during the rainy season.15 The Pedens’ initial complaint (filed January 2, 2026) had claims for theft, fraud, unfair business practices, civil RICO, unjust enrichment, and declaratory relief.16 Their amended complaint (filed July 26, 2026) adds negligence claims based on Whitney’s excavation, his removal of lateral and subjacent support, and his failure to stabilize the site.17 Whitney’s
