Locale property values
Median property value for the Dallas-side sliver of the Farmers-Branch ZIP cluster runs well above the Dallas citywide median ($295k) because the overlap sits in higher-value Far North Dallas and Preston Hollow edges. Texas property-tax rate is inherited at the Dallas County effective rate of 1.66 percent. Values in the City-of-Farmers-Branch portion of these ZIPs (not covered here) run lower per CoreLogic county reports.

Locale overlays (3)
- airport-noise-zone — Dallas-side parcels in the Farmers-Branch-addressed cluster sit under the Dallas Love Field Class B airspace shelf and within the broader noise-exposure contour; small subset is within 6-8 miles of Addison Airport (ADS) noise-monitoring radius. Standard residential construction in City of Dallas is exempt from Part 150 noise-attenuation mandates but lenders may require disclosure. · +2% cost
Not a prohibition; minor construction-spec delta. Addison Airport traffic is the more proximate noise source for the northern portion of the cluster. - flood-zone — Farmers Branch Creek tributary runs through portions of ZIP 75234; FEMA-mapped Zone AE parcels exist along the creek corridor. Dallas-side parcels near the creek are subject to Dallas floodplain ordinance. · +21d · +15% cost
Not all Farmers-Branch-addressed Dallas parcels are in the SFHA; the impact applies only to creek-corridor parcels. Owners should pull the FEMA Flood Map Service Center report for their specific address before underwriting. ADU in Zone AE must be elevated to or above Base Flood Elevation. - other — ADU Overlay District status: as of 2026-04, no Dallas-adopted ADU Overlay District exists in the Farmers-Branch-addressed Dallas sliver (ZIPs 75234/75244). Owners wishing to build an ADU must pursue either a Board of Adjustment special exception ($600 filing fee, 3-6+ month entitlement) or organize a neighborhood-petition overlay application.
This is the single largest regulatory friction point for the locale. Unlike Belmont Addition or Oak Cliff Gateway (where ADUs are allowed by right), no adopted overlay covers this sliver; BoA is the practical path.

Dallas — city ADU rules and incentives
ADU legality: with-restrictions
Cross-listed entry. See dallas-county/dallas.json for the primary record. Dallas's overlay-petition framework is unusual: ADUs are largely opt-in by neighborhood vote rather than allowed citywide.
City cost envelope
$153,500 all-in for a 600 sqft ADU (permit + build). Midpoint scenario.
Permit fee bundle: $3,500 (2026-04).
City viability (selected uses)
City incentives
- Texas Homestead Exemption — Owner-occupied primary residence exemption applies to primary structure; ADU added value generally taxed at full rate.
County: no attribution (synthetic bucket)
No county
This city sits in the state's "no county" bucket — its ADU rules derive directly from state law and city ordinance without a county intermediary. No county-level sections apply.
Texas state — ADU law and programs
State ADU law
Texas has NOT enacted a statewide ADU preemption or ADU-by-right statute. Local governments (municipalities and counties) retain full authority over ADU zoning, setbacks, parking, size limits, owner-occupancy, and permitting. Two recent housing-reform bills in the 89th Legislature (2025) touch density and zoning procedure but do NOT preempt ADU-specific local rules: SB 15 (Bettencourt, signed 2025-06-20, effective 2025-09-01) caps minimum single-family lot sizes in cities over 150,000 in counties over 300,000, and HB 24 (signed 2025-06-20, effective 2025-09-01) raises the protest petition threshold for zoning changes. A dedicated ADU-preemption bill — SB 673 (Hughes, 2025) — passed the Texas Senate on 2025-04-10 and was reported favorably by the House Land & Resource Management Committee on 2025-05-08, but died on the General State Calendar when the 89th Regular Session adjourned on 2025-06-02. In the absence of a state ADU statute, homeowners must consult the ordinance of the municipality (or the county's subdivision rules for unincorporated areas) where the lot sits.
- Texas SB 15 (89R, 2025) — Relating to size and density requirements for residential lots in certain municipalities; authorizing a fee — Prohibits municipalities of population greater than 150,000 located in counties of population greater than 300,000 from imposing minimum lot sizes greater than a specified threshold (3,000 sqft for certain residentially zoned subdivisions; lower for new subdivisions) and limits their authority over setbacks, parking, permeable-surface, and height on those lots. Not ADU-specific, but functionally expands the footprint of small-lot single-family housing in Austin, Dallas, Fort Worth, Houston, San Antonio, and other qualifying cities. Signed 2025-06-20; effective 2025-09-01.
- Texas HB 24 (89R, 2025) — Relating to procedures for changes to a zoning regulation or district boundary — Raises the protest-petition threshold for neighboring property owners who wish to trigger a supermajority city-council vote on a rezoning from 20% to 60%, and constrains the ability of a small minority to block citywide zoning updates. Not ADU-specific; affects the procedural posture of any city-wide ADU-enabling rezoning. Signed 2025-06-20; effective 2025-09-01.
State financing programs
Texas does not operate an ADU-specific statewide loan, grant, or forgivable-loan program comparable to California's CalHFA ADU Grant. The Texas Department of Housing and Community Affairs (TDHCA) administers the state's general housing finance programs — My First Texas Home, My Choice Texas Home, Mortgage Credit Certificates, multifamily Housing Tax Credits, the Homeowner Assistance Fund, and Housing Trust Fund awards. None target ADU construction directly, but several can apply to an ADU as part of a primary-residence purchase or refinance when program criteria are met. ADU-specific financing in Texas is primarily local: the City of Austin's ADU Loan Program (administered through Neighborhood Housing and Community Development) and a handful of smaller pilot programs are the most visible, but these sit at the city tier, not the state tier.
Federal (United States) — ADU-relevant rules and programs
Federal ADU law
The United States has no federal statute that directly regulates accessory dwelling unit entitlement or design. Land-use authority over ADUs resides with states and local governments under the traditional police power. Federal engagement is limited to financing (Fannie/Freddie/FHA/VA/USDA), flood insurance (FEMA/NFIP), and discretionary housing programs (HUD), which are recorded in sibling sections of this file.
Federal financing programs
Federal housing-finance agencies and GSEs set nationwide underwriting rules that govern whether an ADU can be financed, appraised, and counted toward mortgage qualifying income. The relevant actors are Fannie Mae, Freddie Mac, FHA (HUD), VA, and USDA Rural Development.
Federal tax credits
There is no ADU-specific federal tax credit. ADUs may incidentally qualify for existing federal energy-efficiency and clean-energy tax credits when the ADU construction includes qualifying measures.
Federal housing programs
HUD administers several discretionary programs that can fund ADU-related activity at the grantee's election, but none is an ADU-specific program.
