How Dallas Handles Historic Preservation: A Practical Guide

Dallas maintains 206 local ordinances across all categories, and 4 of those deal specifically with historic preservation. Here is a breakdown of what the city actually requires, what is prohibited, and where Dallas falls on the strict-to-permissive spectrum compared to other cities.

HPOZ Rules

Inside a Dallas historic overlay district, no one may alter a site or a structure, including additions or expansions, without a certificate of appropriateness from the city under Development Code Sec. 51A-4.501(g). Applications go through either a fast routine-maintenance review or a full standard review, and violating the rule is a continuing daily offense.

Key details: Permit required: Certificate of appropriateness (COA). Routine review timeline: 20 days after complete filing. Director's documentation notice: Within 10 days of application. Penalty structure: Separate offense per day of violation. Max fine: $2,000 per day (Sec. 13-1(a)(2)).

Sec. 51A-4.501(g)(2) makes altering a site or structure in a historic overlay district without a COA a separate offense for each day, or part of a day, the violation continues, running from the first unlawful act until either a COA is obtained or the property is restored to its pre-violation condition. Fines are capped citywide at $2,000 per day for zoning-related offenses under Sec. 13-1(a)(2).

This is not one of those rules that cities tend to ignore. Dallas actively enforces its hpoz rules requirements.

HCM Demolition Controls

For historically significant buildings outside a historic overlay district, Dallas can impose a demolition delay overlay under Sec. 51A-4.504 that pauses a demolition permit for at least 45 days so the owner and city officials can discuss preservation alternatives before the building official may issue the permit.

Key details: Minimum building age: 50 years old. Phase I review deadline: 10 days to assess criteria. Phase II meeting deadline: Within 45 days of determination. Public notice sign deadline: 2 working days after determination. Outcome after 45 days if no deal: Permit must be granted.

The ordinance is procedural rather than punitive: it does not authorize the city to deny a compliant demolition permit outright, only to delay issuance while alternatives are discussed. Proceeding with demolition without going through the referral and delay steps, or without the required permit, is enforced as a building-code and zoning violation under the city's general penalty, Sec. 13-1(a)(2), fined up to $2,000 per day.

Historic-Cultural Monuments

Dallas designates historic and culturally significant places through a Historic Overlay District under Sec. 51A-4.501, requiring three or more of ten statutory characteristics before city council can adopt a designation ordinance. Once designated, exterior alterations, demolition, and new construction require a certificate of appropriateness from the landmark commission.

Key details: Governing section: Dallas Dev. Code Sec. 51A-4.501. Designation threshold: 3 of 10 listed characteristics required. Reviewing body: 15-member Landmark Commission. Individual property hearings: Minimum 1 public hearing. District/expansion hearings: 2 hearings plus 1 community meeting.

Altering, demolishing, or constructing on a designated historic landmark or within a historic overlay district without a certificate of appropriateness from the landmark commission is a code violation enforced by the Department of Sustainable Development and Construction. Work done during the predesignation moratorium without first obtaining a predesignation certificate of appropriateness or a certificate for demolition or removal is likewise a violation and can be ordered stopped or reversed at the property owner's expense, with the landmark commission and city plan commission reviewing any appeal.

This is not one of those rules that cities tend to ignore. Dallas actively enforces its historic-cultural monuments requirements.

Mills Act Contracts

Texas does not have a California-style Mills Act property-tax contract program. Instead Texas Tax Code Section 11.24 authorizes cities and counties to grant partial property-tax exemptions for designated historic sites, which Dallas implements through its Historic Site Tax Exemption.

Key details: Texas Mills Act equivalent: None; uses Tax Code 11.24. Dallas program: Historic Site Tax Exemption. Eligibility: Designated Landmark or HPD contributor. Typical term: Ten years on improvement value. Trigger: Qualifying rehabilitation completed.

No fines apply, but unauthorized demolition or alterations terminate the exemption retroactively under Tax Code Section 11.24, triggering recapture of back taxes plus interest by the Dallas Central Appraisal District.

Dallas is more permissive than most cities when it comes to mills act contracts. That said, there are still limits.

The Bottom Line

Dallas is tougher than many cities when it comes to historic preservation. Out of the 4 rules covered here, 2 are rated strict. If you are a homeowner, renter, or business owner in Dallas, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.
