Most renovations in San Antonio require a building permit from the Development Services Department. The Residential Improvements Permit covers interior and exterior alterations. Cosmetic work like painting and flooring is generally exempt. Permits can be applied for at 1901 S. Alamo or online.
San Antonio requires building permits for most renovation work including structural modifications, electrical changes, plumbing, HVAC, window/door replacements in exterior walls, roofing, and additions. The Residential Improvements Permit application covers most residential alterations. Permit fees are based on project scope and square footage. Work generally exempt from permits includes painting, wallpapering, flooring replacement, cabinet replacement (without plumbing changes), and minor cosmetic repairs. Homeowners may perform their own work but must pull permits. Licensed contractors must hold valid San Antonio contractor registrations. The Development Services Department offers same-day permits for simple projects at 1901 S. Alamo St. Complex renovations requiring plan review take 10-15 business days. Electrical, plumbing, and mechanical work require separate trade permits. Properties in designated historic districts require Historic Design Review before obtaining building permits. The Develop SA online portal allows application submission and status tracking.
Unpermitted renovation work can result in stop-work orders, Code Enforcement citations, fines up to $500 per day, and orders to restore the property. Unpermitted work may cause issues during property sales.
