When Permits Are Required (Structural, Electrical, Plumbing, HVAC)

Permits are required for any work that affects the structure, safety systems, or major systems of your home. This includes: foundation work, framing, roof replacement, electrical rewiring, plumbing changes, HVAC replacement, additions, deck and patio construction, fence over 6 feet, swimming pools, and solar panel installation. Always check with San Antonio Development Services before starting work.

What it means for you: the permit protects you, your family, and the next buyer by making sure the work is inspected and safe. Skipping it on structural or electrical work is how a small project becomes a big problem at resale, so check before you swing the hammer.

When Permits Aren't Required (Cosmetic)

Cosmetic improvements generally do not require permits: interior and exterior painting, flooring replacement (same type), cabinet replacement (same footprint), countertops, light fixture replacement (same wiring), landscaping (non-structural), and fence under 6 feet. However, even cosmetic work should follow building codes.

The money angle: the cosmetic work that needs no permit is exactly the high-ROI stuff, paint, flooring, cabinets, countertops, so you can refresh a home fast without the waiting and the fees. Just keep the same footprint and the same wiring, and you are clear.

How to Get a Permit (Development Services)

San Antonio's Development Services Department handles building permits. Apply online or in person. You'll need detailed plans, contractor information, and owner authorization. The process typically takes 1-4 weeks depending on project complexity. Licensed contractors can pull permits on your behalf. Fees are based on project value.

The real-world tip: build the permit timeline into your project schedule, not around it. If your contractor says the job can start tomorrow without a permit on a structural project, that is the moment to slow down and ask why.

Cost of Permits

Permit costs vary by project scope. Simple permits (water heater replacement) may cost $50-$100. Major renovations (additions, structural changes) can cost $500-$2,000 or more based on the project valuation. The cost of permits is small compared to the potential cost of dealing with unpermitted work later.

The money math: a few hundred dollars in permit fees is cheap insurance compared to the resale problem an unpermitted addition creates. Buyers, appraisers, and lenders all ask about permits, and the answer can change whether a deal closes at all.

What Happens With Unpermitted Work (Selling Issues, Insurance Problems)

Unpermitted work creates several problems. When selling, buyers' lenders may not finance homes with unpermitted additions or major modifications. Insurance companies may deny claims for damage related to unpermitted work. The city can require you to remove unpermitted work or obtain retroactive permits with penalties. Disclose unpermitted work to buyers to avoid legal issues.

The real-world consequence: unpermitted work can quietly kill a sale at the financing stage, which is the worst time to find out. If you are buying, verify the permits before you commit, and if you are selling, get the work legal before you list.

How to Verify Permits

When buying a home, check that previous renovations had proper permits. San Antonio Development Services allows online permit searches by address. Verify that permits were closed (inspected and approved) not just opened. If the seller can't provide permit documentation, proceed with caution. Unpermitted work by a previous owner becomes your problem.

Make it a great one: the address search takes ten minutes and can save you from buying someone else's unpermitted project. Do it during the option period, and if the permits do not line up with the work, we talk about it before we close, not after. I am on your side either way.
