A Starr County building permit is not issued by the county. Like most Texas counties it has no adopted residential building code and no building inspection program for unincorporated areas. What applies are the environmental and land records that govern rural construction — and in a border county, subdivision platting carries requirements that reach considerably further than in an interior Texas county. We file and track all of it for you.
Starr is a border county on the Rio Grande with Rio Grande City as the seat. Texas applies Model Subdivision Rules and enhanced platting requirements in border-region counties, aimed at ensuring new residential subdivisions have adequate water and wastewater service before lots are sold.
Those rules exist because of the colonias problem — residential subdivisions historically platted and sold without water, sewer, or paved access. Starr County has been among the counties most affected. If your project involves dividing land here, platting is the primary constraint, not a downstream formality.
Covers unincorporated Starr County. Rio Grande City, Roma, Escobares, and La Grulla permit their own territory — confirm whether the parcel is inside a city limit before assuming county rules apply.
Border-county platting rules can decide feasibility. Texas applies Model Subdivision Rules and enhanced platting requirements in border counties, requiring adequate water and wastewater service for new residential subdivisions. If your project involves dividing land in unincorporated Starr County, establish those requirements before anything else — they can determine whether a subdivision is viable at all.
What requires a county permit in Starr County?
The question in unincorporated Starr County is not which building permit you need. It is which environmental and land records your project triggers — with subdivision platting carrying materially more weight here than in an interior county — and whether the parcel is genuinely outside every city limit.
On-site sewage carries the clearest statewide requirement. Texas requires a permit for any OSSF under Texas Health and Safety Code Chapter 366 and TCEQ rules at 30 TAC 285, administered locally by an authorized agent.
Still required
- On-site sewage facility permit — required statewide
- Licensed site evaluation as part of the OSSF application
- Subdivision plat with border-region water and wastewater service requirements
- Model Subdivision Rules compliance where applicable
- Floodplain development where the parcel touches a mapped hazard area
- 911 address assignment for new structures
- Driveway or culvert access onto a county road
Not required by the county
- County building permit — not issued
- County building code compliance — none adopted
- County construction inspections across the trades
- TDI windstorm certification — Starr County is not first-tier
Starr County building department: who handles permitting
Starr County administers on-site sewage permitting through environmental health as the local authorized agent, with floodplain administration, subdivision platting, and road access handled through county offices and Commissioners Court at Rio Grande City.
Confirm requirements with the county directly. Starr publishes less permitting detail online than the larger Texas counties, and given the border-region platting overlay, both the county and the state have roles worth clarifying early.
| Detail | Information |
|---|---|
| Building permits | Not issued — no county building code for unincorporated areas |
| OSSF / septic | Starr County environmental health, as local authorized agent |
| Governing rules | Tex. Health & Safety Code ch. 366 and TCEQ rules at 30 TAC 285 |
| Subdivision | Border-region Model Subdivision Rules and enhanced platting requirements |
| Floodplain, plats, roads | Starr County offices and Commissioners Court, Rio Grande City |
| County seat | Rio Grande City |
| Windstorm | Starr County is NOT a first-tier TDI designated county |
| Inside city limits | Rio Grande City, Roma, Escobares, La Grulla |
If the project involves subdividing land, treat platting as the primary constraint rather than a downstream formality. Border-region requirements around water and wastewater service can determine feasibility, not merely process.
Starr County permits: record types and what each covers
The permit-type question works differently in a Texas county, and differently again on the border. Starr County has no adopted building code for unincorporated areas and issues no residential building permits, so there is no record-type matrix. What exists is a set of environmental and land records — with subdivision platting carrying enhanced border-region requirements that reach further than in an interior county.
What Starr 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 | Starr County Environmental Health | 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 | Starr County Environmental Health | 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 |
| 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 Starr County
In unincorporated Starr 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 Rio Grande City city limits the picture changes completely: the city permits solar like any other municipality. The jurisdiction question is the first question.
Roofing permits in Starr County
A residential roof covering replacement in unincorporated Starr 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.
Starr County sits on the Rio Grande in deep South Texas at roughly 105 to 115 mph ultimate design wind speed under the codes regional cities adopt, well inland of the TDI designated catastrophe area and outside any windstorm certification requirement — unlike Cameron County downriver. Heat, hail, and intense solar exposure govern roof assembly here.
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.
Starr County permit cost and fees
Starr County charges no building permit fees because it issues no building permits. Costs attach to OSSF permitting and its licensed site evaluation, floodplain permitting where applicable, platting, and road access.
On a subdivision, the water and wastewater service requirements under border-region rules are frequently the dominant cost — extending service to a rural tract is a capital item, not a permitting fee.
| Fee component | How it works |
|---|---|
| Building permit | None — not issued by the county |
| OSSF permit | County fee plus licensed site evaluation and system design |
| Subdivision plat | Enhanced border-region requirements; water and wastewater must be adequate |
| Water and wastewater service | Capital cost on a subdivision, not a permit fee |
| Floodplain development | County fee where applicable |
| Road access / culvert | County fee plus materials and installation |

Starr County trade permits
There is no county trade permit program in unincorporated Starr County. Electrical, plumbing, and mechanical work is neither permitted nor inspected by the county. On-site sewage is the exception and it is permitted and inspected.
Electrical
No county permit or inspection. A TDLR-licensed electrician remains the standard, and TDLR retains enforcement authority in unincorporated areas.
Plumbing
No county permit for interior plumbing. The septic system is permitted through environmental health with a licensed design behind it.
Mechanical / HVAC
No county permit or inspection. TDLR licensure applies to the contractor regardless of whether a permit exists.
Inside a city limit
Rio Grande City, Roma, Escobares, and La Grulla permit and inspect trades normally. Jurisdiction determines everything.
Starr County permit application: how to apply step by step
Check against Rio Grande City, Roma, Escobares, and La Grulla.
If land is being divided, border-region Model Subdivision Rules and water and wastewater service requirements apply and can determine feasibility.
Soil testing on the specific parcel is required for OSSF permitting and determines system type and house siting.
File with county environmental health. Aerobic systems carry a continuous maintenance contract and a recorded affidavit.
Determine flood hazard status, obtain a 911 address, and permit driveway access onto county roads.
With no county code or inspection, build to a recognised code edition anyway and keep records of licensed trades and engineered plans.
Inspections in Starr County
Starr County performs no residential construction inspections in unincorporated areas. There is no foundation, framing, rough-in, or final building inspection, and no county certificate of occupancy.
On-site sewage installations are inspected as part of the permitting process, and aerobic and surface application systems carry continuing maintenance and inspection obligations under state rules after the permit issues.
Private third-party inspection is worth considering on a new build. In a county that generates no construction record, it is the only independent documentation a lender, insurer, or future buyer will have.

Frequently asked questions
Who issues building permits in Starr County?
No one, for general residential construction in unincorporated areas — Starr County has no adopted residential building code and no building inspection program. The records that do apply are administered separately: on-site sewage through Starr County Environmental Health, floodplain development through the county floodplain administrator, plats through Commissioners Court, and road access through the precincts. Inside Rio Grande City city limits, the city permits normally.
How do I get a permit in Starr 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 Starr County?
Texas has no statewide building code, and Starr 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.
Does Starr County issue building permits?
No, not for general residential construction in unincorporated areas. The county has no adopted residential building code and no building inspection program, which is the standard Texas county position. On-site sewage permitting, floodplain requirements, subdivision platting, addressing, and county road access are the records that do apply. Confirm current requirements directly with the county before relying on any summary.
Why is subdividing land harder in a border county?
Because Texas applies Model Subdivision Rules and enhanced platting requirements in the border region, aimed at ensuring new residential subdivisions have adequate water and wastewater service before lots are sold. Those rules exist in response to the colonias problem — subdivisions historically platted and sold without water, sewer, or paved access. In practice they can determine whether a rural subdivision is viable at all, so establish them before committing.
Does windstorm certification apply in Starr County?
No. Starr County is not one of the fourteen first-tier TDI designated catastrophe counties, so WPI-8 certification does not attach here. Cameron County downriver on the coast is first-tier, and Hidalgo County between them is not. That means a reroof in Rio Grande City carries no certification requirement while the same work in Brownsville does — confirm the county before scoping exterior work anywhere along the river.
Do I need a permit to install solar panels in Starr County?
Yes. Photovoltaic installations in Starr 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 Starr County?
Yes, in most cases. A roof covering replacement requires a permit in most Texas municipalities including Starr 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 Starr County?
In a Texas county it is the difference between no county jurisdiction and possible county jurisdiction. Residential construction in unincorporated Starr 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 Starr County?
Not in unincorporated Starr 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 Starr County?
Because Starr 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 Starr County permit types online?
Largely no. Starr County administers its records through county offices at Rio Grande City rather than a unified permitting portal, and it publishes less permitting detail online than the larger Texas counties. Expect a manual, phone-and-counter process, and treat direct confirmation with the county as a necessary step — particularly on anything involving subdivision.
