San Antonio Building Permits: When You Need One and Who Applies

Permits confuse homeowners for two reasons: which projects need one, and who is allowed to apply. For a home inside San Antonio city limits, check project permit requirements and who can apply with the City's Development Services Department (DSD). Confirm your address and exact scope with the permitting office before work starts; homes outside city limits may have different requirements.

Work that needs a permit

DSD's residential permits page lists remodeling, repairs and demolition, larger room additions and any two-story addition, re-roofing that changes the pitch, new fences, carports, manufactured home installations and swimming pools among the projects that require permits. It also notes that one project can need several permits at once: building, electrical, mechanical and plumbing.

DSD's Getting Started page adds a few specifics homeowners ask about:

• Accessory buildings: a permit is required for an accessory structure larger than 300 square feet.
• Decks: no permit is needed only if the deck avoids all four triggers: over 200 square feet, more than 30 inches high, attached to the house, or serving an exit door.
• Fences: new fences need a permit, and so do larger repairs or replacements, measured by continuous length.
• Electrical and HVAC: DSD tells homeowners they must use licensed trade contractors for electrical and heating or air conditioning work.

Work that usually doesn't

DSD's No Permit Required list includes:

• Cabinets and countertops
• Carpet and wood or laminate flooring
• Interior finishes: painting, plastering, drywall repair, wallpapering and tiling
• One-story detached storage sheds or playhouses up to 300 square feet that meet setbacks
• Retaining walls under 4 feet tall
• Sidewalks and driveways inside your property line
• Replacing broken window glass or existing doors
• New siding over existing siding

The same page warns that properties in historic, neighborhood conservation or corridor districts may face design and material restrictions even when no permit is needed.

Who applies for which permit

DSD's residential permits page sorts applicants this way:

The Getting Started page fills in the rest. General contractors cannot pull trade permits or request trade inspections; those can only be requested by a licensed trade contractor. Every contractor licensed by the City or State must be registered with the City before any permit is issued. And the property owner owns all building permits regardless of who pulls them, while trade permits belong to the trade contractors.

If a contractor asks you to apply for a permit in your name for work they will perform, ask why before you agree.

When plans go through review

DSD's plan review page says new homes, room additions over 1,000 square feet and second-floor additions go through plan review. The submittal includes a site plan with distances to property lines, an energy report, construction drawings and a foundation plan prepared by a licensed engineer. As of October 2026, DSD says initial review typically takes three business days, and corrections go back to the applicant if the drawings don't meet code. Properties in flood plains, conservation districts, corridor overlays or historic areas get added reviews. Our home addition permit guide walks through that process step by step, and the garage conversion and ADU guide covers converting existing space.

Historic districts

The City's Office of Historic Preservation states on its project review page that changes to the exterior of properties in historic districts must have a Certificate of Appropriateness. If your home is a landmark or sits in a historic district, plan that review into your schedule. Our historic home renovation guide explains how it fits with permits.

Inspections

DSD's inspections page says building inspections cover foundations, framing, electrical, mechanical and plumbing at each stage. Inspections can be scheduled through the BuildSA portal or by phone, and a request placed before midnight is scheduled for the next day. Failed inspections carry a re-inspection fee. Keep work open until the inspection for that stage passes; drywall over an uninspected rough-in can mean opening the wall again.

Fees

Fees depend on the permit type and project. DSD publishes current schedules, so check there rather than relying on older figures.
