Do I need a permit to replace my roof in Austin, TX?

Often not, for a like-for-like reroof inside the city limits. The City of Austin's list of work exempt from building permits includes, for one- and two-family dwellings and townhouses not more than three stories, "asphalt shingles that replace existing asphalt shingles" and "replacement of any roof covering that does not adversely affect the roof structure," in both cases "unless the property is located in the Wildland-Urban Interface area and 50% or more of the roofing is being replaced," and "roof decking that does not exceed 128 square feet" (City of Austin, Work Exempt from Building Permits). A permit line on a quote for that work deserves two questions: which jurisdiction, and can I see the receipt.

What the city says is exempt

The Development Services Department keeps a public page of residential work that does not need a building permit. Three entries concern roofs (City of Austin, Work Exempt from Building Permits):

• Asphalt shingles that replace existing asphalt shingles, unless the property is located in the Wildland-Urban Interface area and 50% or more of the roofing is being replaced.
• Replacement of any roof covering that does not adversely affect the roof structure, with the same Wildland-Urban Interface exception.
• Roof decking that does not exceed 128 square feet.

The same page lists painting, papering, tiling, carpeting, cabinets, countertops, fencing and siding repairs as exempt, which matters if the roofing quote bundles gutters, paint or siding: those lines do not need a permit either.

When a permit is still needed

The exemption has edges, and a contractor who knows Austin will know them. A permit is needed when the property is in the Wildland-Urban Interface area and half or more of the roof is being replaced, which describes most full reroofs in the WUI. It is needed when the work changes the roof structure: new rafters or trusses, a change of pitch, adding a dormer, or replacing more than 128 square feet of decking. It is needed when the building is more than three stories or is not a one- or two-family dwelling or townhouse. And electrical, mechanical or plumbing work done at the same time, such as moving a vent stack or adding a powered attic fan, has its own permit rules.

The exemption is also the City of Austin's. Round Rock, Pflugerville, Cedar Park, Georgetown and San Marcos are separate cities with their own permit rules, and unincorporated county land is not covered by the Austin list. An Austin mailing address does not always mean the property is inside the city limits. The contractor should be able to say which jurisdiction the house is in; the county appraisal district record will confirm it.

What a permit line on the quote means

Where a permit is required, the fee is on the city's published schedule and is a pass-through: the contractor pays it and shows you the receipt. Where the work is exempt, there is no fee to pass through, and a permit line is either a mistake, a charge for the contractor's time dealing with the city, or padding. Ask which. In the sample roofing quote we use on this site, a $450 permit line sits on an asphalt-for-asphalt reroof in ZIP 78745, and the report marks it "ask about the permit exemption" rather than "wrong," because the house might be in the WUI or outside the city limits (City of Austin; see the sample report).

There is a second reason to ask. A contractor who pulls a permit where one is required is putting the job in front of a city inspector, which protects you. A contractor who charges for a permit and does not pull it has taken your money and left you without the inspection. The receipt closes that gap.

What to ask

1. Is the house inside the Austin city limits or in another jurisdiction, and is it in the Wildland-Urban Interface area?
2. Is any decking being replaced, and how many square feet?
3. Is the roof structure being changed in any way?
4. If a permit is required, what is the fee on the city's schedule, and will you give me the permit number and receipt?
5. If no permit is required, what is the permit line for?

These questions take a contractor a minute to answer. Our Quote Check asks them for you when a permit line appears on an exempt job, alongside the labor and material checks described in is my roofing quote too high.

Questions

Do I need a permit to replace shingles in Austin?

Not for asphalt shingles replacing existing asphalt shingles on a one or two family home or townhouse up to three stories, unless the property is in the Wildland-Urban Interface area and 50% or more of the roofing is replaced. The City of Austin lists this work as exempt.

How much roof decking can I replace without a permit in Austin?

Up to 128 square feet, according to the City of Austin's list of work exempt from building permits. More than that, or any change to the roof structure, needs a permit.

My contractor put a permit fee on the quote. Is that normal?

Where a permit is required, the fee is a pass-through and you should get the receipt and permit number. Where the work is exempt, ask what the line is for. Do not assume the house is inside the city limits; the contractor should say which jurisdiction applies.

Does the Austin exemption apply outside the city limits?

No. Round Rock, Pflugerville, Cedar Park, Georgetown and San Marcos are separate cities with their own permit rules, and unincorporated county land is not covered by the Austin list.
