Permits and Inspections for Exterior Work

I once inspected a home just outside Buda, Texas, where a previous owner had poured a low retaining wall and framed up a covered patio without pulling a single permit. It looked solid enough standing on the porch. But there was no inspection record, no engineering on file, and a footing I had no way to verify once it was buried under six inches of soil. When the buyers asked me if it was “up to code,” the honest answer was that nobody could say — and that uncertainty knocked real money off the sale price.

My name is Dale Whitfield, and I’ve spent the last 19 years inspecting homes and working alongside contractors around Buda, Kyle, and the rest of Hays County. Unpermitted exterior work — decks, patios, retaining walls, driveway cuts — is one of the most common red flags I run into out here, and most owners skip the permit step without ever understanding what it’s actually protecting them from.

What actually needs a permit around Buda

People assume permits are only for additions and new rooms, but exterior work trips the requirement more often than folks expect. In and around Buda and Hays County, you generally need one for:

• Decks and covered patios or carports
• Retaining walls above a certain height (commonly four feet, measured from the bottom of the footing to the top)
• Foundation repairs
• New driveways or driveway approaches that tie into a public road
• Reroofs and water heaters
• Electrical for landscape lighting or an outdoor kitchen

What typically doesn’t need one: painting, minor siding repair, fence replacement under the local height threshold, and most simple landscaping. The exact thresholds vary by jurisdiction, which is exactly why I tell owners to call the building department before assuming anything. One phone call to your city or county’s permitting office — for example, the City of Buda building inspections division — will tell you precisely what your project needs.

Where the four-foot rule comes from

The height threshold on retaining walls isn’t arbitrary. A wall under four feet, freestanding and not holding back a driveway or slope, is generally low-risk enough that most jurisdictions let it go without a permit. Once you cross that line — or once the wall is retaining a surcharge like a slab or a slope above it — the soil pressure behind it changes the engineering enough that most jurisdictions want a stamped design and a footing inspection before anyone pours concrete. On our expansive clay soils, that’s not a bureaucratic formality. A wall built without a verified footing is a wall that leans in five years.

What the process actually costs

The sequence itself is simple: apply, get plan review, pull the permit, do the work, then call for inspections at set stages. For a retaining wall or foundation, an inspector checks the excavation and footing before concrete goes in, because once it’s buried nobody can verify it again. For a covered structure, you’re typically looking at footing, framing, and final inspections.

It feels like friction when you’re standing there waiting on an inspector to show up. But that footing inspection is the difference between a wall that lasts and a wall that leans.

The $200 job that turned into $3,000

Here’s what I see from the inspection side, and it’s a pattern, not a one-off. Unpermitted work creates three problems. First, it may not be safe or durable, because nobody checked the footing, the framing, or the drainage. Second, it complicates resale — a diligent buyer’s agent and inspector will flag work with no permit history, and buyers discount for the unknown. Third, retroactive permitting is genuinely painful. Bringing existing work into compliance can mean opening up finished construction so an inspector can see what’s actually behind the siding or under the slab, and that’s demolition you pay for twice.

I’ve watched an owner spend roughly $3,000 exposing and re-inspecting a patio slab that would have cost about $200 in permit fees to do right the first time. That gap is the whole argument for pulling the permit up front.

How I tell owners to handle it

• Call the local building department before you sign a contract, and ask specifically which parts of your project need permits.
• Put it in writing that the contractor is responsible for pulling permits; a pro who resists that is a red flag.
• Never let concrete cover a footing until the required inspection has passed.
• Keep every permit and inspection record — it’s paperwork that protects you at resale.

The contractor you hire should be handling most of this without being asked twice, which is one more reason to vet them carefully before signing anything. I go through how to check a company’s licensing and history in how to vet an exterior contractor.

Questions I get asked on almost every job

Do I need a permit for a retaining wall in the Austin area? Usually yes if the wall exceeds four feet measured from the bottom of the footing to the top, or if it retains a surcharge like a driveway or slope. Walls at or above that height typically also require an engineer’s stamped design. Shorter, freestanding landscape walls often don’t need one, but confirm the exact threshold with your local building department before you build.

What happens if exterior work was done without a permit? It doesn’t automatically have to come out. But you’ll likely need to apply for a retroactive (after-the-fact) permit and have the work inspected, which can mean opening up finished construction to expose the footing or framing. It also complicates resale, since buyers and their inspectors discount unpermitted work. Budget for both the fees and possible corrective work — as the patio example above shows, the corrective side is usually the expensive part.

Who is responsible for pulling the permit, me or my contractor? Make it the contractor’s responsibility and put it in the contract. A licensed pro pulling the permit puts their name — and their liability — on the work. If a contractor asks you to pull an owner permit for a job they’re doing, treat that as a warning sign, not a favor.
