Building Code
2024 IBC, adopted as part of City Code Chapter 10 (Building-Related Codes) with San Antonio amendments, effective May 1, 2025

Electric Utility
CPS Energy, the municipally owned utility serving San Antonio and much of Bexar County (the nation's largest municipally owned electric and gas utility), so service, rates, interconnection, and demand charges all run through CPS Energy

San Antonio prioritizes staying on the most current ICC editions and adopted the full 2024 code family (IBC/IECC and companion codes) by Ord. No. 2025-01-30-0075. Separate from the building code, development over the Edwards Aquifer recharge and contributing zones triggers Aquifer Protection and TCEQ water-quality requirements that shape site design on the city's north side.

San Antonio construction is driven by military and healthcare (Joint Base San Antonio and the South Texas Medical Center), a growing manufacturing and data-center base, tourism/hospitality downtown, and strong multifamily and industrial growth along the I-35 and US-281 corridors. Edwards Aquifer protection over the recharge zone is a defining site-development constraint for northern-sector projects.

San Antonio Engineering FAQs

What building and energy codes does San Antonio enforce?
San Antonio adopted the 2024 IBC and 2024 IECC (and the companion 2024 ICC codes) as City Code Chapter 10 by Ord. No. 2025-01-30-0075, effective May 1, 2025. The city prioritizes staying current on ICC editions, so we match building and COMcheck/energy-model documentation to the 2024 edition.
How do Edwards Aquifer rules affect development in San Antonio?
Projects over the Edwards Aquifer recharge and contributing zones - largely the north and northwest - trigger the city's Aquifer Protection requirements and a TCEQ Edwards Aquifer Protection Plan, adding water-quality treatment, impervious-cover controls, and a separate review track. We plan these constraints into the site layout early and run the aquifer review in parallel with building review.
Who provides electric service for a San Antonio commercial project?
CPS Energy, the municipally owned utility (the largest of its kind in the U.S.), serves San Antonio and much of Bexar County, so rates, interconnection, and commercial demand charges all run through CPS Energy. Development Services coordinates the final utility release with CPS Energy after inspections, so we align the electrical design and inspection sequence accordingly.

Commercial permits are submitted and tracked through the BuildSA online portal, where professionals link their licenses and upload plan sets for electronic review. DSD publishes information bulletins (such as the commercial energy submittal bulletin) that define required documentation, and once inspections are approved DSD notifies CPS Energy to release utilities to the site.
