Gas availability: available — Full gas service throughout the 75230 area via Atmos Energy Mid-Tex. Texas HB 17 (2021) prohibits Texas cities from adopting all-electric mandates; Dallas has no electrification ordinance. ADUs in 75230 typically install gas tankless water heater + gas furnace to match main-house fuel profile. ZIP 75251 commercial gas service is separately routed and not relevant to ADU analysis.
Locale property values
ZIP 75230 (the residential component of the Robert E Price delivery area) consistently ranks among the highest-value ZIPs in Dallas, reflecting its Preston Hollow / Northaven / Preston Trail character. Zillow and Redfin ZIP-level trackers for 75230 reported median sale price in the $1.1M-$1.5M range through 2024-2025, roughly 4-5x the Dallas citywide median (~$295K) but below adjacent 75225 ($1.8M-$2.4M). Wide submarket variance: Preston Trail and Northaven Park estate parcels $3M-$10M+; Northaven tract homes $750K-$1.4M; townhomes and condos near Forest Lane and Central $400K-$800K. Effective property-tax rate is the Dallas County countywide effective rate (DISD + City + County + Parkland + Dallas College blended). The Texas Residence Homestead 10% appraisal cap limits year-over-year assessed-value increases on owner-occupied primary residences. ZIP 75251 (commercial) is reported separately under commercial-assessment categories and is excluded from these residential medians.

Locale HOA prevalence
The ZIP 75230 residential area has moderate-to-high HOA / deed-restriction prevalence — higher than typical Dallas single-family neighborhoods but lower than nearby 75225 (Preston) or newer master-planned suburbs (Frisco, Prosper, Plano). The 1950s-1960s subdivisions (Northaven, Walnut Hill Estates, Meadowood) typically have active neighborhood associations or enforceable covenants, while scattered infill parcels along major arterials (Preston, Hillcrest, Midway) may not. The practical ADU impact is similar across both regimes — both layers of private governance typically require approval or consent before a detached accessory dwelling unit may be constructed. ZIP 75251 commercial parcels are commercial-property-association governed (separate regime, not tracked here).
Locale overlays (4)
- airport-noise-zone — Dallas Love Field AICUZ (Air Installations Compatible Use Zones) and DFW International AICUZ both reach portions of North Dallas. The Robert E Price area sits roughly 5 miles east-northeast of Love Field and 11 miles east of DFW. Neither 65 dB DNL noise contour typically reaches ZIP 75230 or 75251 under current flight paths.
Not a practical constraint on ADU construction in the Robert E Price area. No noise-attenuation construction required for residential outside the 65 dB contour. - flood-zone — Bachman Branch and its tributaries cross portions of the Robert E Price residential area near Midway and Marsh. FEMA-mapped Special Flood Hazard Areas (Zone AE) follow the creek corridors in narrow strips; most 75230 parcels sit on the Austin Chalk uplands and are Zone X. · +21d · +15% cost
Approximately 4-7% of 75230 residential parcels touch mapped SFHA along Bachman Branch. Those parcels require elevation certificates, floodplain-ordinance compliance, and typically higher flood-insurance premiums. The majority of 75230 parcels are Zone X. - other — Many ZIP 75230 residential subdivisions carry 1950s-1960s deed restrictions and restrictive covenants that independently govern accessory structures, typically limiting each lot to 'one single-family dwelling'. Enforced under Texas Property Code Ch. 202 (covenant enforcement) by neighbors or by successor HOAs. Key subdivisions with active restrictions: Northaven Park, Walnut Hill Estates, Meadowood, Preston Trail, portions of the Preston Road estate corridor. · +60d
Owners must independently review recorded restrictions before committing to the Dallas BoA special-exception process. Restriction language varies — some subdivisions permit detached accessory structures occupied by family members but prohibit separate rental dwelling. A title attorney's opinion on covenant compatibility typically costs $500-$1,500 and is advisable before filing. - other — ZIP 75251 (commercial corridor along LBJ Freeway near Midway and Inwood) is predominantly zoned MF-*, MU-*, O-*, or PD — not single-family base zoning. Sec. 51A-4.510 requires a single-family base district, so ZIP 75251 parcels are structurally excluded from the Dallas ADU framework regardless of BoA posture.
Relevant only because this USPS locale crosses the commercial/residential ZIP boundary. Owners checking ZIP 75251 parcels for ADU feasibility should expect the zoning predicate to fail before any BoA discussion.

Dallas — city ADU rules and incentives
ADU legality: unclear
Texas leaves ADU regulation to local municipalities under home-rule or Dillon-rule authority. Dallas permits ADUs subject to local conditions per its zoning ordinance.
City cost envelope
$117,300 all-in for a 525 sqft ADU (permit + build). Midpoint scenario.
Permit fee bundle: $2,905 (2026-04).

Dallas County — county ADU rules and overlays
County regulatory overlays
Dallas County's county-level overlays apply only inside its small unincorporated footprint (under 10% of county land, primarily southeastern Dallas County). The two material overlays at county scope are FEMA-mapped Special Flood Hazard Areas administered by Dallas County Public Works under the county's floodplain ordinance, and the countywide Trinity Common Vision Program governing floodplain management along the Trinity River corridor. Inside incorporated cities — where the vast majority of Dallas County residents and ADU-candidate parcels sit — overlay administration is a city function (e.g., the City of Dallas administers its own Escarpment Zone at Dallas Development Code Art. V and its own Floodplain regulations at Div. 51A-5.100). There is no countywide WUI / wildland-fire hazard overlay of the kind seen in California or Washington; North Texas's fire-hazard regime is ESD-by-ESD rather than a county-administered WUI zone.
- Dallas County Floodplain Management (FEMA NFIP participation) — A new ADU in a Zone AE parcel must be elevated to or above the Base Flood Elevation per the county ordinance and is generally not permitted as a basement or ground-floor sleeping space.
- Trinity Common Vision Program — Structures including ADUs proposed within the Common Vision corridor face stricter review than FEMA NFIP alone and may require a No-Rise Certificate from a Texas-licensed engineer.
- On-Site Sewage Facility (OSSF) jurisdiction — An ADU counts as an additional dwelling for OSSF sizing purposes, which can trigger system expansion on undersized lots and may be infeasible on very small unincorporated parcels.
County permitting (unincorporated parcels)
Dallas County regulates construction in unincorporated areas through the Department of Unincorporated Area Services (DUAS), in partnership with the Dallas County Fire Marshal's Office and Public Works. Because the county has no zoning authority (see countyOrdinance), DUAS does not restrict whether an ADU may be built — it regulates only subdivision/plat compliance, residential building-code inspection, on-site sewage (OSSF) compliance, floodplain compliance, 911 addressing, and nuisance abatement. A detached secondary dwelling on an unincorporated parcel is permitted as an ordinary residential structure through DUAS's building-permit pathway; there is no separate 'ADU permit' because there is no county use category for accessory dwellings. Unincorporated Dallas County comprises under 10% of county land area, primarily in the southeastern corner of the county. Most ADU activity in Dallas County occurs in incorporated cities (notably the City of Dallas ADU Overlay at Dallas Development Code Sec. 51A-4.510), which are governed by city-level permitting, not this section.
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.
