Building permits in the City of San Antonio are issued by the Development Services Department (DSD) through the BuildSA permitting system, with in-person help at the Cliff Morton Development and Business Services Center (the "One Stop"). San Antonio is zoned under the Unified Development Code, and its large historic districts and military-overlay zones add review steps for many projects.
This San Antonio building permit guide covers what requires a permit, how fees work, the BuildSA submission process, zoning and historic review, trade permits, and inspections — so your San Antonio project starts clean.
This guide covers the City of San Antonio. DSD permits only work within city limits; unincorporated Bexar County and surrounding cities run their own processes. San Antonio is zoned under the Unified Development Code (UDC), and properties in historic districts or military-influence overlay zones (near Joint Base San Antonio) face added review — confirm yours before designing.
What requires a building permit in San Antonio?
Under the City of San Antonio's adopted construction codes (the International Codes with local amendments), a permit is required for most new construction, renovation, or system work that affects the structure, safety, or utilities of a building. Common triggers include:
Permit required
- New residential and commercial construction
- Additions, including garages and patios
- Interior remodels that move or remove walls
- MEP work — mechanical (HVAC), electrical, or plumbing
- Roofing replacements involving decking or structure
- Accessory structures over 200 sq ft and detached garages
- Fences over 6 feet and major fence replacements
- Demolitions — full or partial removal of a structure
Typically exempt
- Painting, flooring, cabinetry, and cosmetic work
- Like-for-like minor repairs not altering structure or systems
- Small accessory structures under the size threshold (confirm)
- Routine maintenance not extending or rerouting systems
Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get the permit issued before starting work. Building without one exposes the owner to penalties and stop-work orders, and historic-district work without a Certificate of Appropriateness can require reversal. Apply through BuildSA first.
Who handles permitting in San Antonio?
Permitting is administered by the Development Services Department, with the Cliff Morton center serving as the primary intake and payment point. Plans undergo a multi-departmental review that can include zoning, historic preservation, and fire.

San Antonio building permit cost
San Antonio building permit fees are set by the city fee schedule and based on the type and valuation of work, with separate fees for each trade plus applicable technology fees. Plans route through a multi-departmental review before issuance.
Because fee lines are valuation-based and adjusted periodically, confirm current amounts in BuildSA before budgeting. Most building permits are valid for 180 days and stay active as long as inspections progress.
| Fee component | How it works |
|---|---|
| Building / construction fee | Based on type and valuation of work; minimum fees apply |
| Trade permits (E / P / M) | Charged separately per trade unless rolled into a building permit |
| Technology fee | Applied to support the BuildSA permitting system |
| Plan review | Multi-departmental; may include zoning, historic, and fire |
| Certificate of Occupancy | Required for new commercial occupancy or change of use |
| Work-without-permit | Penalties and possible stop-work orders |

San Antonio trade permits
Electrical, plumbing, and mechanical work generally needs its own permit and a state-licensed contractor registered with the City of San Antonio, each filed in BuildSA.
Electrical permits
Required for service installations, panel upgrades, solar PV, and most wiring alterations, performed by a TDLR-licensed electrician registered with the city.
Plumbing permits
Required for new plumbing, repipes, water heater changeouts, fixtures, and gas piping, performed by a TSBPE-licensed plumber. Fees follow the city schedule with a per-permit minimum.
Mechanical (HVAC) permits
Required for HVAC changeouts, ductwork, and refrigeration, performed by a TDLR-licensed mechanical contractor. Specialized systems are permitted and inspected separately.
Miscellaneous & specialty
Reroofs, pools, signs, and fences are permitted separately. Work in San Antonio's historic districts requires a Certificate of Appropriateness from the Office of Historic Preservation, and military-overlay zones near Joint Base San Antonio add height and use review.
Verify your contractor's license. Texas licenses electricians (TDLR), plumbers (TSBPE), and HVAC/mechanical contractors (TDLR) at the state level, and they must register with the City of San Antonio before pulling permits; Texas does not issue a statewide general-contractor license. The property owner is responsible for ensuring a permit is obtained.
How to get a building permit in San Antonio
Confirm scope, zoning & overlays
Verify the work needs a permit, confirm the parcel is inside city limits, and check UDC zoning, historic-district status, and any military-overlay requirements before you design.
Prepare your documents
Assemble the application, valuation, signed plans, energy-code (IECC) compliance, and a Certificate of Appropriateness application if the property is in a historic district.
Apply in BuildSA
Create an account, submit your application, and upload supporting documents — or file in person at the Cliff Morton One Stop.
Multi-departmental review & corrections
Plans route across building, zoning, historic, and fire as applicable. Resolve any comments and resubmit; revisions re-enter review.
Pay fees & pull the permit
Pay the calculated fees in BuildSA, then download and post the permit on site with approved documents available.
Schedule inspections through close-out
Request inspections in BuildSA. Keep the permit active with timely inspections and clear all required inspections to obtain your Certificate of Occupancy.
Inspections in San Antonio
Schedule inspections through BuildSA using your permit number. Typical checkpoints include foundation, rough-in MEP, framing, insulation, and final. Most permits stay valid for 180 days and remain active as long as inspections keep progressing.
A re-inspection fee applies to failed inspections and must be cleared before a final inspection or Certificate of Occupancy can be requested.
