SAN ANTONIO BUILDING PERMIT GUIDE FOR CONTRACTORS (2026)

THE SACONNECT PORTAL AND DEVELOPMENT SERVICES DEPARTMENT

San Antonio building permits are processed by the Development Services Department (DSD) through the SAconnect portal at saconnect.info. SAconnect runs on the Accela Citizen Access platform — the same system used by Austin and many other Texas cities. If you're familiar with the Austin BDS portal, SAconnect will feel familiar. If you're new to Accela, it's worth spending 15 minutes getting oriented before your first application.

Contractor accounts are required to submit applications and upload documents. Public permit searches (by permit number or address) don't require a login. DSD's main office is at 1901 S. Alamo Street in San Antonio, with permit counter hours Monday through Friday, 7:45 AM to 4:30 PM. The main permit inquiry line is (210) 207-1111.

San Antonio has grown significantly in the past decade — it's now the second-largest city in Texas — and DSD has expanded staffing accordingly. Residential permit volumes are high, particularly in the fast-growing north and northwest sides, and timelines reflect this demand. Commercial development near the Medical Center, the South Side corridors, and the downtown urban core adds to commercial review queue depth.

HOW TO SEARCH BY PERMIT NUMBER OR ADDRESS

San Antonio permit numbers follow the format YYYY-BLDG-XXXXXX for building permits. The SAconnect portal search process:

1. 1Go to saconnect.info
2. 2Click "Building" in the top navigation
3. 3Select "Building Permits" from the dropdown
4. 4Choose Permit Number or Address as your search type
5. 5Enter your search term and click Search
6. 6Click the permit record from the results list to view status, reviewer information, and conditions

The permit detail page in SAconnect shows more information than the basic status field. Scroll to the "Conditions" tab — any outstanding conditions that must be resolved before the permit can be issued are listed here. Many permits stall because a condition (like a drainage review sign-off or a tree mitigation fee) is outstanding and not obvious from the status field alone.

WHAT EACH STATUS MEANS IN SAN ANTONIO'S SYSTEM

TYPICAL TIMELINES FOR SAN ANTONIO PERMITS

RESIDENTIAL PROJECTS

Standard residential permits in San Antonio — new single-family homes, additions, accessory dwelling units — typically take 4 to 6 weeksfrom submission to issuance. San Antonio has implemented process improvements in recent years that have helped compression residential timelines. Projects in master-planned communities with pre-approved plans can be faster.

Residential projects near drainage features — including properties in or near FEMA Special Flood Hazard Areas, which are numerous in San Antonio given the city's topography and flood history — require drainage review that can add 2–4 weeks.

COMMERCIAL PROJECTS

Commercial new construction and major renovations run 8 to 12 weeks. Commercial projects near the Medical Center cluster, along Loop 1604 growth corridors, and in the downtown Innovation District have seen higher volume in recent years. Projects requiring site development plan approval from DSD add 4–6 weeks before the building permit review even begins.

TRADE PERMITS

Standalone trade permits — HVAC replacements, electrical panel upgrades, plumbing repairs — typically process in 5 to 10 business days. Some qualify for over-the-counter approval at DSD.

COMMON DELAY SOURCES IN SAN ANTONIO

DRAINAGE REVIEW FOR FLOOD PLAIN PROXIMITY

San Antonio has a significant history with flooding — the San Antonio River watershed covers much of the city, and many properties are in or near regulated flood plains. Projects on properties within FEMA Special Flood Hazard Areas require drainage review by DSD's Stormwater division. This review is separate from the plan review process and must be completed before the building permit can be issued.

Check flood plain status early using FEMA's flood map service center (msc.fema.gov) and San Antonio's own GIS flood plain viewer. If your project is in a flood zone, build the drainage review timeline into your project schedule from the start — finding out at permit submission that you need this review adds weeks.

HISTORIC DESIGN REVIEW COMMISSION

San Antonio has extensive historic district coverage, particularly in the near-downtown and King William neighborhoods. The Historic Design Review Commission (HDRC) must approve exterior changes to buildings in designated historic districts before DSD will issue a building permit. HDRC meets approximately twice monthly.

The HDRC process applies to exterior modifications including window replacements, door changes, siding replacements, roofing, and any visible additions. Contractors doing renovation work in King William, Beacon Hill, Lavaca, or other historic overlay areas need to confirm HDRC applicability before submitting to DSD. HDRC approval adds 4–8 weeks and has specific design guidelines that must be followed.

TREE MITIGATION REQUIREMENTS

San Antonio's Tree Preservation Ordinance protects heritage trees (defined by size and species) on development sites. Projects that will impact protected trees require a tree survey and mitigation plan. Missing this requirement at submission is a common source of corrections on new construction permits, particularly in the older established neighborhoods with large tree canopy.

WHEN TO CALL DSD VS. WHEN TO WAIT

DSD's general rule: if your permit has been in PENDING status for more than a week without moving, call to confirm your application was fully received and isn't sitting in an incomplete submissions queue. The (210) 207-1111 line handles permit status questions — have your permit number and application date ready.

Once in IN REVIEW status, the established review window should be respected before calling. For residential permits, that's generally 3–4 weeks from assignment; for commercial, 6–8 weeks. Calling every few days doesn't accelerate review and clogs the DSD phone lines.

For permits stuck in APPROVED — CONDITIONS status, the conditions tab in SAconnect will tell you exactly what's outstanding. Most conditions are fee-based (drainage fees, park fees, or mitigation fees) and can be cleared quickly once you know what's required.
