Texas Supreme Court weighs estoppel claim after Dallas approves then reverses permit for townhouse

The Supreme Court of Texas on Tuesday heard arguments about whether equitable estoppel can prevent the City of Dallas from enforcing a residential proximity slope (RPS) restriction that the city failed to disclose while approving plans and permits for a townhouse developed by Philip Thompson’s company, PDT.

At issue is whether a seven‑month course of interactions between PDT and city planning staff — which included pre‑purchase inquiries, issuance and reissuance of permits, an inspector’s stop‑work related to a parapet, and a later stop‑work tied to the RPS — supports the trial court’s equitable ruling that the city should be stopped from requiring demolition of the completed structure. Appellate counsel for PDT told the court the house, completed in April 2018 and valued at about $1.5 million, sits vacant and has attracted vandalism and trespass since the city declined to issue a certificate of occupancy.

The case turned on longstanding Texas precedents about when equitable estoppel may be applied against a governmental body. Counsel for PDT pointed to the trial record and argued the facts fit an “exceptional case” described in earlier decisions, including an alleged affirmative misrepresentation by city staff that the applicable height limit was 36 feet and repeated confirmations that allowed construction to proceed. “This is the case to hold them,” counsel for PDT told the court, urging enforcement of the trial court’s equitable remedy. Counsel for the City of Dallas responded that the record does not show legally sufficient evidence of the deliberate affirmative misrepresentation or the other threshold requirements necessary to apply estoppel against a municipality and emphasized that the permitting regime and later administrative processes (including variance requests to the Dallas Board of Adjustment) were available remedies.

Why it matters: The court’s decision will clarify how and when courts can apply equitable doctrines to undo or limit municipal permitting actions after substantial private investments have been made. Petitioners say the city repeatedly misdirected the developer and then refused to issue final inspections and a certificate of occupancy because of a residential proximity slope triggered only by this lot’s unusual triangular shape. The city argues that its staff’s statements reflected the general MF‑2 height rule (36 feet) and that the specific RPS effect depends on parcel location; that distinction, the city says, is for the factfinder.

Key factual points from the argument: counsel for PDT said the developer (1) inquired with city planning before purchasing the lot, (2) was told of a 36‑foot height limit, (3) submitted plans showing 36 feet and received permits in October 2017, (4) received and complied with a stop‑work order focused on a parapet in January 2018 (reducing parapet height to 35 feet), and (5) had the project effectively complete by April 2018 when the city again cited an RPS problem and paused enforcement while suggesting the Board of Adjustment could resolve the issue. Counsel told the court that three variances had been sought and that city staff twice recommended granting a variance, but the Board of Adjustment never did so and the developer’s later variance efforts were denied.

Legal issues debated: Justices pressed counsel on how the court’s precedent in cases referred to in argument (cited in the record as “Superwash,” earlier municipal estoppel cases, Roberts, Moseley v. Texas Health and Human Services Commission, and decisions about when a government benefit or interference with governmental function is required) should be applied here. Petitioners argued this is an “exceptional” case because of the length of time the city repeatedly approved or reapproved work and permitted construction to proceed to substantial completion, while the city argued that applying estoppel broadly would routinely prevent municipalities from responding to constituents and enforcing land‑use ordinances.

Scope and remaining procedural posture: The trial court’s final judgment (described during argument) referenced estoppel as the basis for relief; counsel for PDT has said other equitable theories (quasi‑estoppel, waiver, laches) were tried by consent, but the judgment specifically mentions estoppel. The parties discussed that the petitioner did not make a post‑trial request for findings of fact and conclusions of law, which affects the appellate standard of review because the reviewing courts must presume the trial court made all findings necessary to support its judgment on the unchallenged record.

The argument also noted that media reports and prior litigation indicate other properties in Dallas have been affected by similar RPS enforcement disputes; counsel for PDT said an earlier case involved an attempted demolition of an expensive apartment complex and that the appendix included an article listing 13 buildings and 18 lots allegedly impacted by related issues.

The Supreme Court took the arguments and adjourned; a decision will clarify whether and in what circumstances equitable relief can bar municipal enforcement after a substantial private investment based on permitting communications and later inspections.
