San Antonio adopts ICC model codes with local amendments custom to our climate and community needs. These amendments address specific regional challenges such as extreme heat, soil conditions, and wind loads that are unique to South Texas. Plan reviews, permits, and inspections are managed by DSD to ensure compliance and safety throughout the construction process. The department processes thousands of permits annually, maintaining strict standards while working to streamline the approval process for contractors and homeowners alike.
If your project may extend into next year, note that the 2024 Building Codes are set to become effective on May 1, 2025. This upcoming change will bring new energy efficiency requirements, updated structural provisions, and improved safety standards that reflect the latest industry best practices. Planning ahead for these changes can help you avoid mid-project code transitions that could impact your timeline or budget.

Key Aspects of the San Antonio Building Codes
- Local amendments: San Antonio modifies the ICC codes to address regional conditions (heat, soil, wind) and administrative processes.
- Development Services Department (DSD): The Director serves as the Building Official, overseeing interpretations, plan review, permits, and inspections.
- Unified Development Code (UDC): Beyond the building codes, the UDC governs zoning, subdivision, tree preservation, and landscaping. These requirements can influence choices like how to choose the right roof for your business in San Antonio.
State Regulations and Local Compliance
Texas empowers cities to adopt and amend building codes, but local rules must align with state law. Two statewide programs commonly affecting projects are:
- Texas Department of Licensing and Regulation (TDLR) Architectural Barriers Program, which enforces accessibility under the Texas Accessibility Standards (TAS) (effective March 2012). Projects must meet the stricter of TAS or local provisions.
- TDLR Elevator and Escalator Safety standards (updates effective November 2018) for vertical transportation systems.
The result is a coordinated system: local enforcement of San Antonio building codes plus statewide consistency on accessibility and life-safety.
The Permitting and Enforcement Process
Once you understand the codes, your next step is permits, reviews, and inspections with the Development Services Department (DSD). Working with experienced San Antonio contractors streamlines submittals and helps you avoid delays. The permitting process serves as a critical quality control mechanism, ensuring that all construction work meets minimum safety standards and complies with local regulations. Understanding each phase of this process – from initial application through final inspection – can significantly reduce project delays and unexpected costs.
Role of the Development Services Department
The DSD (1901 S. Alamo Street) is your hub for all building-related activities in San Antonio. This department employs dozens of plan reviewers, inspectors, and administrative staff who work together to ensure construction safety and code compliance. Their responsibilities include:
- Enforcement of all building-related codes through systematic review and field verification
- Plan review of construction documents, typically completed within 10-15 business days for residential projects
- Issuing permits to authorize work, with same-day service available for simple projects
- Inspections at required phases (e.g., foundation, framing, rough-in, energy, final)
- Issuing Certificates of Occupancy when applicable for commercial and multi-family projects
- Providing code interpretations and technical assistance to contractors and property owners
- Maintaining historical records of all permitted work for future reference
The department also offers pre-submittal meetings for complex projects, allowing developers and contractors to discuss code requirements and potential challenges before formal plan submission. This proactive approach can save weeks in the review process and prevent costly redesigns.

Obtaining a Building Permit
Permits are typically required to construct, enlarge, alter, repair, move, demolish, or change occupancy, and for most electrical, gas, mechanical, and plumbing work. The permit process ensures that qualified professionals review your plans and that work is inspected at critical stages. Here’s what you need to know:
- Submittals: Provide dimensioned, scaled plans showing the location, nature, and extent of work. Complex projects may require a registered design professional. Electronic submissions through the BuildSA portal can expedite review times.
- Timing: Follow DSD timelines carefully; abandoned applications (inactive for 180 days) and expired permits (no inspections for 180 days) can add significant cost and delay to your project.
- Annual permits: Available for routine maintenance (e.g., MEP) in certain R-2 occupancies, these permits streamline ongoing maintenance work for property managers.
- Emergency repairs: You may start work immediately to protect life, health, or property, but must apply for the permit within 72 hours of beginning emergency work.
- Fees: Permit fees are based on project valuation and are due at issuance. Additional fees may apply for plan review, re-inspections, and after-hours inspections.
For roofing scopes specifically, understanding the permit requirements is crucial. Most re-roofing projects require permits, as do repairs affecting more than 25% of the roof area. See our practical walkthrough: A guide to roof installation in San Antonio.
Work Exempt from Permits
While many projects require permits, certain minor work is exempt to reduce regulatory burden on homeowners. Examples often exempt from permits include:
- One-story detached accessory structures under 200 sq. ft. (sheds, playhouses)
- Fences not over 7 ft. high (though zoning rules and HOA restrictions may still apply)
- Cosmetic work like paint, wallpaper, tile, carpet, and countertops
- Minor electrical repairs not involving new circuits or service upgrades
- Portable appliances and window air conditioning units
- Prefabricated swimming pools under 24 inches deep
However, it’s important to note that structural changes, major roof work (re-roofing/structural alterations), most MEP installations/alterations, and occupancy changes generally require permits. Even exempt work must comply with applicable codes and may require inspections if it connects to permitted systems. When in doubt, call DSD at (210) 207-1111 for clarification – a quick phone call can prevent costly violations and ensure your project proceeds smoothly.
Inspection Process and Requirements
Once your permit is issued, inspections become the next critical phase. San Antonio requires inspections at specific construction milestones to verify code compliance. Common inspection types include foundation, framing, MEP rough-in, insulation, and final inspections. Schedule inspections at least 24 hours in advance through the BuildSA portal or by calling the inspection request line. Failed inspections require correction and re-inspection before work can proceed, potentially delaying your project timeline. Working with experienced contractors who understand inspection requirements can minimize failed inspections and keep your project on schedule.
The Permitting and Enforcement Process
For permitting in San Antonio, DSD oversees plan review, permits, inspections, and Certificates of Occupancy to ensure compliance with San Antonio building codes. Start with complete, scaled plans and confirm whether your scope requires a permit before work begins. Keep schedules tight to avoid abandoned applications or expired permits.
