Permit Office (AHJ)
City of San Antonio Development Services Department (DSD)
San Antonio, TX · Licensed Professional Engineering
Energy compliance handled as engineering, not paperwork — documentation matched to the exact code edition your permitting jurisdiction enforces.
San Antonio enforces the 2024 IECC with local amendments under City Code Chapter 10, effective May 1, 2025, so COMcheck or ASHRAE 90.1 modeling must target that current edition - DSD's commercial energy information bulletin defines the required submittal package. In hot-humid climate zone 2A the compliance economics reward low-SHGC glazing, envelope air-sealing to limit humid-air infiltration, and right-sized high-efficiency cooling with real dehumidification, more than added roof insulation. We coordinate envelope, mechanical, and lighting compliance as one package and resolve plan-check comments through the BuildSA electronic review workflow.
Code adoptions and local amendments change on multi-year cycles. The state source verification date is 2026-07-28; we verify the governing editions with City of San Antonio Development Services Department (DSD) at project kickoff.
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.
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.
Because CPS Energy is a city-owned utility, its commercial demand charges and interconnection process govern service planning; DSD coordinates the final utility release with CPS Energy after inspections. Water and wastewater are San Antonio Water System (SAWS).
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.
Reviewed 2026-09-11. Code editions and local requirements can change; confirm the current requirements with the authority having jurisdiction before design.
