A San Antonio building permit is issued by the Development Services Department, which manages land and building development in the city and issues Certificates of Occupancy. Applications and documents are submitted through the BuildSA online portal. We file and track it for you.
San Antonio has the most generous shed exemption of any major Texas city — accessory structures are exempt up to 300 square feet, against 120 in Houston and no exemption at all in Fort Worth. That is a genuine planning advantage on outbuildings, and it is specific to this city.
Where a permit is required for a shed over 300 square feet, the fee is $150 for structures up to 500 square feet, and the city requires a foundation inspection by a licensed engineer, a framing inspection, and a final inspection — plus an insulation inspection if the space is insulated.
Applies inside San Antonio city limits in Bexar County. Schertz, Converse, Leon Valley, Alamo Heights, and Live Oak permit independently. Confirm the parcel before filing.
Exempt from a permit is not exempt from setbacks. The Unified Development Code sets the general standards, but specific setback distances depend on your property’s zoning district. Accessory structures must maintain a setback from side and rear property lines and cannot be placed in the front yard — regardless of whether the structure needs a permit.
What requires a permit in San Antonio?
San Antonio requires a permit for construction, alteration, and repair work affecting structure, systems, or occupancy, reviewed against the codes the city has adopted.
Because Texas has no statewide building code, the adopted editions and any local amendments are San Antonio’s own. Confirm the current adopted set with the department before designing.
Permit required
- New residential and commercial construction, additions
- Structural and load-bearing alterations
- Interior remodels and commercial finish-out
- Accessory structures over 300 square feet
- Any accessory structure with utilities connected
- Reroofing and exterior envelope work
- Electrical, plumbing, and mechanical work
- Change of occupancy or use; demolition
Typically exempt
- Accessory structures of 300 square feet or less, without utilities
- Painting, wallpapering, tiling, and floor coverings
- Cabinet and countertop replacement
- Note: setback and placement rules under the UDC apply regardless of permit exemption
San Antonio building department: who handles permitting
Development Services manages land and building development in the City of San Antonio, issuing building permits and licences for construction and Certificates of Occupancy, with BuildSA as the online submission portal.
The Unified Development Code governs zoning, setbacks, and land use alongside the building codes. On any project touching an accessory structure, a setback, or a change of use, the UDC is the document that decides the answer.
| Detail | Information |
|---|---|
| Authority | City of San Antonio Development Services Department |
| Online portal | BuildSA — submit permit applications and documents online |
| Certificates of Occupancy | Issued by Development Services |
| Zoning | Unified Development Code — setbacks determined by zoning district |
| Shed exemption | Up to 300 square feet — the largest threshold among major Texas cities |
| Shed permit fee | $150 for structures up to 500 square feet, where a permit is required |
| Accessory inspections | Engineer foundation inspection, framing, final, plus insulation if insulated |
| County | Bexar County — ch. 233 commercial authority via the Fire Marshal only |
Confirm zoning district before assuming a setback. The Unified Development Code sets general standards, but the specific distances depend on the district — so two identical sheds on different lots can face different placement rules.
San Antonio permits: record types and what each covers
A building permit is one record among many. Development Services issues work under separate record types through BuildSA, and filing under the wrong one is a rejection rather than a correction. In San Antonio the Unified Development Code sits alongside the building code, governing zoning and setbacks independently — so permit exemption and placement compliance are two separate questions.

Solar permits in San Antonio
Solar is permitted as its own record type in most Texas jurisdictions rather than rolled into a general building permit, and residential and commercial photovoltaic are usually separate records with different document sets. Solar thermal — passive water and pool heating — is a third, distinct record.
A photovoltaic submittal is reviewed on two tracks at once: structural (roof load path, attachment spacing, uplift) and electrical (conductor sizing, rapid shutdown, point of interconnection). A single-line diagram and a signed and sealed structural attachment detail are the two attachments most often missing on a first submittal.
Texas HOA law is narrower than most installers assume. 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 expressly preserves the association's right to require prior architectural approval and to impose placement and appearance conditions. Approval cannot be unreasonably withheld, and conditions that cut estimated production materially are not enforceable. Practically: get the HOA submittal moving in parallel with the permit rather than treating it as optional.
Texas SB 1202 changed this materially on September 1, 2025. Codified at Tex. Local Gov't Code §247.0025, it lets authorized third parties — licensed engineers, electrical inspectors, and Texas master electricians — perform the plan review and inspections for a home backup power installation instead of the jurisdiction. The definition covers generators, energy storage systems, and associated equipment serving a one- or two-family dwelling at 600 volts or less. Construction may begin on submission of the notice, the third party has 15 days to report results, and the regulatory authority must issue the approval on a short statutory clock. Jurisdictions that process work this way do not review or inspect it, and responsibility for code compliance sits with the third-party reviewer and the contractor of record. Note the boundary: it is a backup-power provision, so a straight grid-tied photovoltaic array with no storage is not automatically inside it, and separate electrical or plumbing permits are still generally required for service release. Confirm how San Antonio is administering SB 1202 before assuming either path.
Utility interconnection runs parallel to the building permit, not inside it. Permission to Operate is issued by the utility after the final electrical inspection clears, and in deregulated territory the interconnecting utility is the wires company rather than the retail provider.
Roofing permits in San Antonio
A roof covering replacement requires a permit in most Texas municipalities. Repairs below the local threshold may not, but the threshold is scope-specific and set locally — confirming it with the building department before tear-off is cheaper than an after-the-fact permit.
Texas has no statewide product approval system, so there is no central listing to check a roofing product against. Compliance runs against the code edition the jurisdiction has actually adopted and the local amendments layered on top of it. Those amendments are where the binding requirements live, and they change from city to city inside the same county.
Texas Department of Insurance windstorm certification — the WPI-8 process — applies only in the designated seaward counties along the Gulf. San Antonio is not a seaward county, so WPI-8 certification does not attach here and roofing contractors licensed for inland work do not need TDI appointment for this jurisdiction.
Hail is the governing weather risk across most of inland Texas, not wind. Impact-resistant Class 3 and Class 4 shingles carry insurance premium credits from most carriers, and under Tex. Prop. Code §202.011 a property owners' association cannot prohibit shingles that are wind or hail resistant, or that improve energy efficiency, provided they otherwise match the roof's appearance requirements.
Reroof inspections are typically sequenced by the jurisdiction, commonly a decking or nail-off inspection before the covering goes down and a final afterward. Covering the deck before the required intermediate inspection means tearing it back open.
Texas has no statewide building code and no statewide general contractor license. The code edition and the amendments that bind your submittal are adopted locally, and contractor registration with the jurisdiction is frequently the gate that has to clear before a record type can even be filed. On commercial work, projects over the statutory threshold also register separately with TDLR for Texas Accessibility Standards review, which runs outside the building permit entirely.
San Antonio sits in Bexar County at roughly 105 to 115 mph ultimate design wind speed under the adopted code, well inland of the TDI designated catastrophe area and outside any windstorm certification requirement. Hail governs, and South Central Texas storm cells drive concentrated reroof demand.
San Antonio permit cost and fees
San Antonio permit fees follow the city fee schedule and scale with the type and valuation of work, with separate trade permit fees and separate records for specialty work.
Confirm current figures with the department before budgeting from a prior project, and confirm whether contractor registration adds a lead-time item.
| Fee component | How it works |
|---|---|
| Building permit | Scales with type and valuation of work |
| Shed over 300 sq ft | $150 for structures up to 500 square feet |
| Engineer foundation inspection | Required on permitted accessory structures — a professional cost |
| Trade permits (E / P / M) | Separate fee per trade, filed by the licensed contractor |
| Certificate of Occupancy | Issued by Development Services |
| Re-inspection | Charged when a checkpoint fails and is re-requested |

San Antonio trade permits
Electrical, plumbing, and mechanical work each need their own permit pulled by the state-licensed contractor for that trade. Texas licenses the trades through TDLR and the TSBPE and does not issue a statewide general contractor licence.
Electrical
Service and panel work, new circuits, solar PV, EV charging, and backup power — performed by a TDLR-licensed electrician.
Plumbing
New plumbing, repipes, water heaters, fixtures, and gas piping — performed by a TSBPE-licensed plumber.
Mechanical / HVAC
Installations, non-like-for-like changeouts, ductwork, and venting, reviewed against the mechanical and energy codes as adopted.
Specialty
Signs, pools, fences, accessory structures, and demolition each run their own record and review path.
San Antonio permit application: how to apply step by step
Check against Schertz, Converse, Leon Valley, Alamo Heights, and unincorporated Bexar County, which permits commercial only via the Fire Marshal.
Setback distances depend on the district, and accessory structures cannot be placed in the front yard.
Accessory structures at or under 300 sq ft without utilities are exempt; above that a permit and engineer foundation inspection apply.
Submit permit applications and documents through the portal.
Respond to review comments, pay fees, and take the permit. Post it on site before work begins.
Schedule inspections, clear the final, and obtain the CO from Development Services where the scope requires one.
Inspections in San Antonio
Development Services performs construction inspections against the adopted codes, running the standard sequence with checkpoints set by the permit record.
On permitted accessory structures the sequence is specific: a foundation inspection by a licensed engineer, a framing inspection, and a final inspection — with an insulation inspection added where the space is insulated.
Keep the permit posted and approved plans on site, and clear correction notices before requesting a re-inspection.

Frequently asked questions
Who issues building permits in San Antonio?
City of San Antonio Development Services Department issues building permits for everything inside San Antonio city limits, handling plan review, permit issuance, and construction inspections. Work outside the city limits falls to Bexar County, and Texas counties have sharply limited building authority in unincorporated areas.
How do I get a permit in San Antonio?
Confirm the scope triggers a permit and that zoning allows it, prepare the plan set and site plan, file through BuildSA with contractor licensure in place, respond to plan review comments, pay fees and take issuance, then run the inspection sequence through final. Contractor credentialing is the step most often missed and it blocks everything downstream.
What codes apply in San Antonio?
Texas has no mandatory statewide building code. Municipalities adopt and amend model codes themselves, so San Antonio enforces I-Codes with San Antonio amendments; Unified Development Code. The local amendments are where the binding requirements live, and they differ from neighboring cities working off the same model code. Confirm the current adopted editions with the department before designing to a specific one.
Do I need a permit for a shed in San Antonio?
Not under 300 square feet. San Antonio has the most generous accessory-structure exemption of the major Texas cities — 300 square feet, against 120 in Houston and no exemption at all in Fort Worth. Where a permit is required, for sheds over 300 square feet, the fee is $150 for structures up to 500 square feet, and the city requires a foundation inspection by a licensed engineer, a framing inspection, and a final inspection, plus an insulation inspection if the space is insulated. Setback rules under the Unified Development Code apply either way.
What does the Unified Development Code govern?
Zoning, setbacks, and land use. The UDC sets the general standards, but specific setback distances depend on your property’s zoning district. As a general guideline, accessory structures must maintain a setback from side and rear property lines and cannot be placed in the front yard. That applies whether or not the structure itself needs a building permit — permit exemption and zoning compliance are separate questions.
What happens outside San Antonio city limits?
The framework changes sharply. Unincorporated Bexar County exercises ch. 233 authority only — commercial, public-accessible, and multi-family construction through the Fire Marshal’s Office, with a Permit Verification Form gating the building permit behind stormwater, floodplain, drainage, and platting clearances. The county has no authority to regulate residential construction, inspect it, or issue a residential certificate of occupancy. Confirm the parcel before assuming either set of rules governs.
Do I need a permit to install solar panels in San Antonio?
Yes. Photovoltaic installations in San Antonio 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 San Antonio?
Yes, in most cases. A roof covering replacement requires a permit in most Texas municipalities including San Antonio, 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 San Antonio?
Residential work is generally a single-discipline review filed as a master permit with trades filed against it. Commercial work in San Antonio runs concurrent review across building, fire, and zoning, requires signed and sealed plans for every affected discipline, and can carry impact and concurrency fees on top of permit fees. Change of use adds accessibility and life-safety review.
Do trade permits need to be pulled separately in San Antonio?
Yes in most cases. Electrical, plumbing, and mechanical work is permitted separately by the licensed contractor for each trade and filed against the master building permit. Each trade permit carries its own fee and its own inspection sequence.
What happens if I file under the wrong permit type in San Antonio?
The application is rejected rather than corrected. San Antonio Permits and Licensing closes the record, the filing is resubmitted under the correct record type, and the review clock restarts from zero. Confirming the record type before filing is the cheapest step in the entire process.
Can I apply for all San Antonio permit types online?
Yes. BuildSA lets you submit permit applications and documents online, and Development Services publishes separate residential and commercial permit guidance alongside it. Confirm contractor registration requirements and inspection request methods with the department before assembling a package.
