A Dallas County building permit applies only to unincorporated areas, where construction and land development occur through a Permit Review Process managed by the Department of Unincorporated Area Services. We confirm jurisdiction and file the county records for you.
The Permit Review Process is deliberately multi-department. DUAS runs it in partnership with the Dallas County Fire Marshal’s Office, and it involves other departments including Health and Human Services, the various Road and Bridge Districts, and Public Works.
Dallas County is overwhelmingly incorporated, so the first question on any project is whether the parcel is genuinely outside every city limit. Where it is not, the city permits instead and none of this applies.
Covers unincorporated Dallas County. Dallas, Irving, Garland, Mesquite, Grand Prairie, Richardson, DeSoto, and Duncanville permit their own territory — confirm whether the parcel is inside a city limit or an extraterritorial jurisdiction before assuming county rules apply.
Your application file stays open for one year — and only one year. The application file shall remain open for a period of one year from the date received at Dallas County, and the owner is required to complete and submit all documentation within that time frame. On a project that stalls, that clock is easy to lose track of.
What requires a county permit in Dallas County?
Dallas County is one of the Texas counties that genuinely permits, but only within the categories state law allows. Local Government Code ch. 233 reaches new commercial, public-accessible, and multi-family buildings and substantial improvements — it does not extend to ordinary single-family residential construction.
Alongside that sit the environmental and land records every Texas county administers: on-site sewage facility permitting, floodplain development, subdivision platting, addressing, and county road access.
County record required
- Development permit for residential or non-residential construction and installation
- Grading and filling
- Floodplain work
- On-site sewage facility permitting
- Sand and gravel operations
- Fire Marshal review through the Permit Review Process
- Subdivision plat, addressing, and county road access
- Certain permits applied for individually — confirm with DUAS
Outside county building authority
- County building permit for ordinary single-family residential construction
- County residential certificate of occupancy
- County trade permits of the municipal kind for residential work
- Work inside a city limit — Dallas, Irving, Garland, Mesquite, Grand Prairie, Richardson, DeSoto, and Duncanville permit independently
Dallas County building department: who handles permitting
Within unincorporated areas of Dallas County, construction and land development occurs through the permitting and inspections process per County and State regulations, described as the Permit Review Process. It is managed by the Department of Unincorporated Area Services.
DUAS can be reached on 214-653-6568 or at Development@DallasCounty.org. Certain permit types are applied for individually — Public Works GIS handles some of them on 214-653-6444.

Dallas County permits: record types and what each covers
Dallas County exercises real permitting authority in unincorporated areas under Local Government Code ch. 233, reaching commercial, public-accessible, and multi-family construction and substantial improvements. The records below reflect that authority plus the environmental and land records that apply alongside it.
What Dallas County actually issues
| Record | What triggers it | Who administers it | Notes |
|---|---|---|---|
| OSSF permit to construct | Installing, altering, repairing, or extending an on-site sewage facility where no public sewer is available | the county authorized agent | Required statewide; soil evaluation by a licensed site evaluator is part of the application |
| OSSF license to operate | Issued after the permit to construct requirements are met and the system passes inspection | the county authorized agent | Also triggered on transfer of ownership of an existing system |
| Floodplain development permit | Placing fill, setting a structure, or developing in or near a mapped special flood hazard area | County floodplain administrator | Substantial improvement and substantial damage rules attach to existing structures |
| Subdivision plat | Dividing land in the unincorporated county | Commissioners Court and county engineering | Road, drainage, and access standards apply |
| 911 address assignment | New structures and new access points needing an address | County addressing / emergency management | Usually a prerequisite for utility service |
| Right-of-way and driveway culvert | New or modified access onto a county road | County road and bridge / precinct | Culvert sizing set by drainage conditions |
| Water well registration | Drilling a water well | the applicable groundwater conservation district | Groundwater districts operate independently of the county |
| Development permit | Residential or non-residential construction, grading, filling, floodplain work, OSSF, sand and gravel operations | Department of Unincorporated Area Services | Application file remains open one year from the date received |
| Fire Marshal review | Construction in unincorporated areas | Dallas County Fire Marshal’s Office | Partners with DUAS in the Permit Review Process |
| Ch. 233 commercial / multifamily | New commercial, public-accessible, or multifamily buildings, and substantial improvements, where the county has adopted the authority | Commissioners Court | Scope is set by county order; confirm adoption before assuming it applies |
County reaches this
- On-site sewage facilities, everywhere in the state
- Floodplain development and substantial improvement
- Subdivision of land and county road access
- Addressing, and fire code where separately adopted
County generally does not
- Issue residential building permits in unincorporated areas
- Conduct residential construction inspections
- Issue a residential certificate of occupancy
- Enforce a residential building code absent a county order adopting one
Solar permits in Dallas County
In unincorporated Dallas County there is generally no county building permit for a residential rooftop or ground-mount photovoltaic system, because the county does not regulate residential construction. That is a jurisdictional fact rather than a green light: the electrical work still has to be performed by a TDLR-licensed electrician to code, and the utility still governs interconnection.
Utility interconnection is the real gate. The interconnecting utility — the wires company in deregulated territory, or the electric cooperative serving the parcel in much of rural East Texas — runs its own application, engineering review, and Permission to Operate process, and it is not waived by the absence of a county permit.
Under Tex. Prop. Code §202.010 a property owners' association cannot prohibit a solar energy device outright, and any dedicatory provision that does is void — but the statute preserves the association's right to require prior architectural approval and to impose placement and appearance conditions. Approval cannot be unreasonably withheld.
Inside Dallas city limits the picture changes completely: the city permits solar like any other municipality. The jurisdiction question is the first question.
Roofing permits in Dallas County
A residential roof covering replacement in unincorporated Dallas County generally does not require a county permit, for the same reason: Texas counties have no general authority over residential construction outside city limits.
Two things still apply. If the structure sits in a mapped special flood hazard area, the county floodplain ordinance can reach the work through substantial improvement rules — and cumulative improvement value is what triggers them, so a reroof after other recent work can cross the threshold on its own. And commercial or multifamily buildings can fall under the county's Ch. 233 authority where it has been adopted.
Texas has no statewide product approval system and no central listing to check a roofing product against. Hail is the governing risk across East Texas, and impact-resistant Class 3 and Class 4 shingles carry insurance premium credits from most carriers. Under Tex. Prop. Code §202.011 a property owners' association cannot prohibit wind or hail resistant shingles, or shingles that improve energy efficiency.
Dallas County sits in the North Texas hail belt at roughly 105 mph ultimate design wind speed under the codes regional cities adopt, far from the designated catastrophe area and outside any TDI windstorm requirement. Hail governs. Note that almost all reroof work in this county happens inside a city limit rather than unincorporated territory.
Texas has no statewide building code and no statewide general contractor license. In the unincorporated county the practical compliance surface is the trades — TDLR for electrical and mechanical, the TSBPE for plumbing — plus the county's environmental and floodplain records, rather than a building department.
Dallas County permit cost and fees
Dallas County charges permit and plan review fees for the categories it regulates, alongside OSSF permitting, floodplain, platting, and road access records.
Confirm the current fee schedule directly — metro county fee orders are revised more often than the published pages suggest, and third-party review costs sit outside the county fee where that model applies.
| Fee component | How it works |
|---|---|
| Development permit | Per the county schedule; applied through DUAS |
| Fire Marshal review | Through the Permit Review Process |
| OSSF permit | County fee plus licensed site evaluation and design |
| Floodplain work | County fee where applicable |
| Sand and gravel operations | Separate permit category |
| Subdivision plat | Filing and review fees, plus survey and engineering |

Dallas County trade permits
Dallas County does not run a municipal-style residential trade permit programme. Trade licensure remains a state matter through TDLR and the TSBPE, and on commercial and multi-family work the county’s fire and building review reaches the systems that matter most for life safety.
Electrical
No county residential trade permit. TDLR licensure applies, and TDLR retains electrical and accessibility enforcement authority in unincorporated areas.
Plumbing
No county residential trade permit for interior plumbing. On-site sewage is permitted separately where no public sewer is available.
Mechanical / HVAC
No county residential trade permit. TDLR licensure applies to the contractor regardless.
Fire protection
Fire alarm, sprinkler, and suppression systems are reviewed and permitted by the county on commercial, public-accessible, and multi-family work.
Dallas County permit application: how to apply step by step
Dallas County is overwhelmingly incorporated. Check against Dallas, Irving, Garland, Mesquite, Grand Prairie, Richardson, DeSoto, and Duncanville.
Call 214-653-6568 or email Development@DallasCounty.org to confirm which records your project triggers.
Some permit types are applied for separately rather than through the main process — Public Works GIS handles some on 214-653-6444.
The application file stays open one year from the date received, and all documentation must be submitted within that window.
The process runs with the Fire Marshal’s Office, Health and Human Services, Road and Bridge Districts, and Public Works.
Track the clock from the date the county received the application, not from when you started work on it.
Inspections in Dallas County
Construction and land development in unincorporated Dallas County occurs through the permitting and inspections process per County and State regulations, managed by DUAS in partnership with the Fire Marshal’s Office and other departments.
Because the process spans several departments, confirm which body inspects which element before scheduling — a Road and Bridge item and a Fire Marshal item are not requested the same way.
Keep the permit and approved documentation on site, and clear correction notices before requesting a re-inspection.

Frequently asked questions
Who issues building permits in Dallas County?
No one, for general residential construction in unincorporated areas — Dallas County has no adopted residential building code and no building inspection program. The records that do apply are administered separately: on-site sewage through the county authorized agent, floodplain development through the county floodplain administrator, plats through Commissioners Court, and road access through the precincts. Inside Dallas city limits, the city permits normally.
How do I get a permit in Dallas County?
Start by confirming the parcel is actually unincorporated, because that single question changes everything and a mailing address will not answer it. If it is, work the records the county does issue rather than looking for a building permit: septic first, since it constrains siting and carries the longest lead time, then floodplain, plat, addressing, and road access as the project triggers them.
What codes apply in Dallas County?
Texas has no statewide building code, and Dallas County has not adopted one for unincorporated areas, so no building code is enforced there. State rules still govern on-site sewage facilities, and the county’s floodplain ordinance governs development in mapped flood hazard areas. Trade work remains subject to state licensing through TDLR and the TSBPE. Inside city limits, the municipality’s adopted codes apply in full.
Who handles permits in unincorporated Dallas County?
The Department of Unincorporated Area Services manages the Permit Review Process, in partnership with the Dallas County Fire Marshal’s Office and involving other departments including Health and Human Services, the various Road and Bridge Districts, and Public Works. DUAS is reachable on 214-653-6568 or at Development@DallasCounty.org. Note that certain permits must be applied for individually rather than through the main process.
How long do I have to complete a Dallas County application?
One year. The application file shall remain open for a period of one year from the date received at Dallas County, and the owner is required to complete and submit all documentation within that time frame. Track that clock from the county’s receipt date rather than from when you began preparing — on a project that stalls for financing or design changes, it is easy to lose.
What kinds of work need a Dallas County permit?
Development activities in the unincorporated areas of Dallas County need a permit, and the category is broad: residential or non-residential construction and installation, grading and filling, development generally, floodplain work, on-site sewage facilities, and sand and gravel operations. Because Dallas County is overwhelmingly incorporated, confirm first that the parcel is genuinely outside every city limit — if it is not, the city permits instead.
Do I need a permit to install solar panels in Dallas County?
Yes. Photovoltaic installations in Dallas County are permitted under a dedicated solar record type reviewed on both a structural and an electrical track. Solar thermal — passive water and pool heating — is a separate record. Under Tex. Prop. Code §202.010 a homeowners' association cannot ban a solar energy device outright, but it may still require prior architectural approval and impose reasonable placement conditions, so run the HOA submittal alongside the permit. Since September 1, 2025, Tex. Local Gov't Code §247.0025 (SB 1202) also permits third-party plan review and inspection of home backup power installations — generators and energy storage for one- and two-family dwellings at 600 volts or less — in place of jurisdiction review. Utility interconnection and Permission to Operate still run in parallel.
Does a roof replacement require a permit in Dallas County?
Yes, in most cases. A roof covering replacement requires a permit in most Texas municipalities including Dallas County, though minor repairs can fall below the local threshold. Texas has no statewide product approval system and no central product listing, so compliance runs against the locally adopted code edition and its local amendments. Hail rather than wind is the governing risk inland, and Tex. Prop. Code §202.011 bars an HOA from prohibiting wind or hail resistant shingles.
What is the difference between a residential and a commercial permit in Dallas County?
In a Texas county it is the difference between no county jurisdiction and possible county jurisdiction. Residential construction in unincorporated Dallas County is largely outside county authority. New commercial, public-accessible, and multifamily buildings, plus substantial improvements, are the categories Local Government Code ch. 233 lets a county reach — but only where Commissioners Court has adopted that authority, so confirm it rather than assuming.
Do trade permits need to be pulled separately in Dallas County?
Not in unincorporated Dallas County — there is no county trade permit program and no county trade inspection. Electrical, plumbing, and mechanical work should still be performed by contractors licensed through TDLR and the TSBPE, and the septic connection is permitted and inspected separately. Inside city limits, trade permits work normally.
What happens if I file under the wrong permit type in Dallas County?
Because Dallas County does not run a building permit program, the more common failure is filing nothing at all — assuming that no building permit means no requirements, and missing the septic, floodplain, plat, or addressing record the project actually triggered. Those are enforced, and unwinding them after construction is materially harder than filing them in order.
Can I apply for all Dallas County permit types online?
Partly. Dallas County publishes its permit process information online through the Department of Unincorporated Area Services and Public Works, but the process is administered through county offices rather than a single unified portal. Contact DUAS on 214-653-6568 or at Development@DallasCounty.org to confirm the current process and which records apply.
