Unincorporated Galveston County does not maintain a general countywide building permit program in the municipal sense. What it runs instead is a substantial floodplain permitting operation through Engineering, Floodplain Permitting and Right-of-Way — and on a low-lying coastal county, that is where the real constraints live.
The county starts you at a map rather than a form. Before beginning the permit application process you use the county GIS map to determine information required within the application: whether the property is in unincorporated Galveston County at all, its flood zone, its distance from mean high tide, and whether it sits within a concrete regulated area.
An Owner Acknowledgment is required for all applications, and depending on the permit type you may be prompted to upload additional documents before the application can be submitted. Allow 5 to 7 business days for an initial response, and up to 10 business days for large-scale development.
Covers unincorporated Galveston County, including the Bolivar Peninsula. Galveston, Texas City, La Marque, Dickinson, League City, Friendswood, Hitchcock, Santa Fe, Kemah, and the county’s smaller cities and villages permit their own territory — though windstorm requirements apply countywide. Confirm the parcel on the county GIS map before filing anything.
Start with the GIS map, not the application. The county directs applicants to use it first to establish whether the property is in unincorporated Galveston County, its flood zone, its distance from mean high tide, and whether it is within a concrete regulated area. Those four answers determine which documents the application will require — and one of them determines whether you are in the right jurisdiction at all.
What requires a county permit in Galveston County?
The question in unincorporated Galveston County is not which building permit you need, because there is no general countywide building permit program. It is which specialised approvals your project triggers — floodplain, beachfront and dune, fire marshal, utility district, drainage, or health district — depending on site conditions.
On the Bolivar Peninsula and within 1,000 feet of the shoreline, Beach Front Construction Certificate and Dune Protection Permit applications attach. Those are coastal instruments with no inland equivalent, and they are the reason a Bolivar project is not comparable to a mainland one.
County record required
- Floodplain development permit — the primary county record
- Owner Acknowledgment — required for all applications
- Beach Front Construction Certificate on Bolivar and within 1,000 ft of shore
- Dune Protection Permit for dune-area work
- On-site sewage facility permitting through the county health district
- Right-of-way permits for work in county right-of-way
- Fire marshal, utility district, or drainage approvals depending on site conditions
Not a general county building permit
- A general countywide building permit — the county does not maintain one
- County building code compliance of the municipal kind
- County trade permits for electrical, plumbing, or mechanical
- Windstorm certification itself — that is a TDI process, not a county permit
Galveston County building department: who handles permitting
Galveston County Engineering, Floodplain Permitting and Right-of-Way administers the floodplain permit process, with the county GIS map as the starting point for determining site conditions and required documentation.

On the Bolivar Peninsula, confirm utility service before design. Public water runs through the Bolivar Peninsula Special Utility District at (409) 684-3515 and public sewer through Undine at (409) 684-9941, with private septic handled through the county — and which of those serves a parcel shapes what can be built on it.
In 2025, building permits issued in unincorporated Galveston County authorized 171 new privately owned housing units, all of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.
Galveston County permits: record types and what each covers
Unincorporated Galveston County maintains no general countywide building permit program, so there is no record-type matrix of the municipal kind. What exists is floodplain permitting plus a set of specialised approvals — coastal, fire marshal, utility district, drainage, health district — that attach according to site conditions. The GIS determination is what tells you which.

Solar permits in Galveston County
Inside Galveston city limits the picture changes completely: the city permits solar like any other municipality. The jurisdiction question is the first question.
Roofing permits in Galveston County
Galveston County is Gulf coast from the mainland to the Bolivar Peninsula, and roofing here is an insurance question as much as a code question. The county permits the floodplain aspects; TDI certifies the envelope; and on Bolivar the dune and beachfront records sit on top of both.

Galveston County permit cost and fees
Galveston County charges floodplain and specialised permit fees rather than a valuation-based building permit fee, because it maintains no general countywide building permit program.
The larger costs on a coastal parcel are elevation compliance, the surveys and certificates that document it, and — on Bolivar — beachfront and dune requirements. Windstorm certification is a separate TDI cost again.
| Fee component | How it works |
|---|---|
| General building permit | None countywide — not maintained by the county |
| Floodplain development permit | County fee; 5–7 business day initial response |
| Beach Front Construction Certificate | Bolivar Peninsula and within 1,000 ft of shore |
| Dune Protection Permit | Dune-area work; coastal requirement |
| OSSF permit | County health district; site evaluation and design separate |
| Windstorm certification | TDI process and cost, not a county fee |

Galveston County trade permits
There is no county trade permit program in unincorporated Galveston County, because there is no general county building permit program. Trade work remains subject to state licensure through TDLR and the TSBPE, and on-site sewage is permitted through the county health district.
Electrical
No county trade permit. A TDLR-licensed electrician remains the standard, and TDLR retains enforcement authority in unincorporated areas.
Plumbing
No county trade permit for interior plumbing. On-site sewage is permitted through the county health district where no public sewer is available.
Mechanical / HVAC
No county trade permit. TDLR licensure applies to the contractor regardless.
Windstorm-scope work
Roof coverings, vents, exterior wall coverings, skylights, windows and entry doors, garage doors, shutters, mechanical equipment, and solar panels.

Determine whether the property is in unincorporated Galveston County, its flood zone, its distance from mean high tide, and whether it is within a concrete regulated area. Everything else follows from those answers.
The Owner Acknowledgment is required for all applications, and the permit type may prompt additional uploads before submission is possible.
On the Bolivar Peninsula and within 1,000 feet of the shoreline, prepare Beach Front Construction Certificate and Dune Protection Permit applications.
Check water, sewer, or septic service for the parcel and obtain addressing through the Galveston Central Appraisal District.
Allow 5 to 7 business days for an initial response, and up to 10 business days for large-scale development.
Galveston County is first-tier. Arrange WPI-8 certification alongside construction rather than after — the certifiable details are concealed once the envelope closes.
Inspections in Galveston County
Galveston County does not run a municipal-style construction inspection sequence in unincorporated areas, because it maintains no general building permit program. Its verification centres on floodplain and coastal compliance.
Elevation certificates and the documentation supporting flood zone compliance are the records that matter most here, and they govern flood insurance rating for the life of the structure.
The TDI windstorm inspection runs separately with a TDI-appointed engineer or qualified inspector, and has to be sequenced into construction because the certifiable details are concealed once the envelope closes.

Frequently asked questions
Who issues building permits in Galveston County?
No one, for general residential construction in unincorporated areas — Galveston County has no adopted residential building code and no building inspection program. The records that do apply are administered separately: on-site sewage through Galveston County Health District, floodplain development and right-of-way permits through Galveston County Engineering, Floodplain Permitting and Right-of-Way, and plats through Commissioners Court. Inside Galveston city limits, the city permits normally.
Want this handled start to finish?
Get a free quote →How do I get a permit in Galveston 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 Galveston County?
Texas has no statewide building code, and Galveston 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 Galveston County issue building permits?
Not as a general countywide program. Unincorporated Galveston County does not maintain a municipal-style building permit operation. Projects there may instead need specialised county or district approvals — on-site sewage, floodplain, fire marshal, utility district, drainage, or health district — depending on site conditions. Floodplain permitting through Engineering, Floodplain Permitting and Right-of-Way is the primary county record.
What is required for a Bolivar Peninsula project?
More than a mainland one. In addition to floodplain permitting and the Owner Acknowledgment required on all applications, properties on the Bolivar Peninsula and within 1,000 feet of the shoreline carry Beach Front Construction Certificate and Dune Protection Permit applications. You will also need to confirm utility service — public water through the Bolivar Peninsula Special Utility District, public sewer through Undine, or private septic through the county — because that shapes what is buildable.
How do I know if my property is in unincorporated Galveston County?
Use the county GIS map, which the county directs applicants to consult before starting the permit application process. It establishes whether the property is in unincorporated Galveston County, its flood zone, its distance from mean high tide, and whether it is within a concrete regulated area — all of which the application requires. Galveston, Texas City, La Marque, Dickinson, League City, Friendswood, Hitchcock, Santa Fe, Kemah, and the county’s smaller cities and villages each permit their own territory under their own codes.
Do I need a permit to install solar panels in Galveston County?
Usually not from the county in unincorporated Galveston County: Texas counties generally do not issue residential building permits, so there is normally no county solar permit. The electrical work must still be done by a TDLR-licensed electrician, and the utility runs its own interconnection review and Permission to Operate. Inside a city, the city’s solar permit applies. Under Tex. Prop. Code §202.010, a homeowners' association cannot ban a solar energy device outright, but it may require prior architectural approval and impose reasonable placement conditions.
Inspections are where schedules slip.
Get a free quote →Does a roof replacement require a permit in Galveston County?
Usually not from the county in unincorporated Galveston County: Texas counties generally do not issue residential building permits, so a reroof normally needs no county permit, though the county floodplain rules can still reach the work through substantial improvement. Inside a city, the city’s roofing permit rules apply. 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 Galveston County?
In a Texas county it is the difference between no county jurisdiction and possible county jurisdiction. Residential construction in unincorporated Galveston 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 Galveston County?
Not in unincorporated Galveston 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 Galveston County?
Because Galveston 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 Galveston County permit types online?
Partly. Galveston County runs its floodplain permit application process with an online GIS map and document uploads, prompting for additional documents based on permit type before an application can be submitted. Allow 5 to 7 business days for an initial response and up to 10 for large-scale development. Windstorm certification is a separate TDI process outside the county system entirely.
