If you're planning a roof replacement, new windows, a deck, or a patio cover, there's an easy assumption to make:
"If my neighbor didn't need a permit, I probably don't either."
That can be a costly assumption.
Permit requirements are not uniform across the Austin area. A project that is exempt from a permit in Round Rock may require one in Austin. A roof replacement that doesn't require a permit in one city may have different requirements if you're modifying the roof structure, working in a special hazard area, or doing additional work at the same time.
And then there are properties that aren't actually inside a city at all.
Before starting an exterior project, you need to know which jurisdiction governs the property, what work you're doing, and whether the project changes the structure or simply replaces existing materials.
Here's how to think about it.
First: Who Has Jurisdiction Over Your Property?
This is the first question homeowners should answer before asking whether a permit is required.
Living in "Austin" doesn't necessarily mean the City of Austin is the permitting authority.
Your property could be:
Inside the City of Austin
Inside Round Rock
Inside Cedar Park
Inside Leander
Inside Georgetown
Inside another municipality
In unincorporated Travis County
In an ETJ or another jurisdiction with additional requirements
Travis County specifically notes that its Development Services department handles development outside corporate city limits, while different jurisdictions can have different rules within their areas.
That is why a contractor should verify the actual property jurisdiction instead of simply assuming that "Austin-area rules" apply.
Do Roof Replacements Need a Permit in Austin?
This is one of the areas where homeowners can get conflicting answers.
In the City of Austin, replacing existing asphalt shingles with asphalt shingles is generally exempt from a building permit, as is replacement of other roof coverings when the work does not adversely affect the roof structure.
But there is an important exception.
Austin's current exemption rules include additional requirements for properties in the Wildland-Urban Interface (WUI). For example, asphalt shingle replacement can lose its exemption when 50% or more of the roofing is being replaced on a property within the WUI.
Austin's WUI requirements can also affect the materials and construction details used on roofs, decks, patios, windows, siding, and other exterior components. More than half of Austin is currently covered by one of the city's WUI zones.
So "it's just a reroof" doesn't always tell the whole story.
What about Round Rock?
Round Rock is more straightforward for a standard residential reroof: the city states that a residential re-roof does not require a permit.
However, if you're modifying the roof rather than simply reroofing, a residential remodel permit may be required.
That's an important distinction:
Replacing the roof covering is different from changing the roof.
If you're replacing decking, changing the structure, altering the roof configuration, or combining roofing with other structural work, don't assume the reroof exemption still applies.
Do Window Replacements Need a Permit?
This is another area where city rules can be surprisingly different.
In Austin, residential window replacement is treated as permitted work rather than simply being automatically exempt. Austin's residential permitting information specifically includes replacement windows among its residential permit categories, and its express-permit system provides a streamlined path for qualifying size-for-size window replacements.
That means a homeowner shouldn't assume that replacing a window with the exact same size automatically means "no permit."
Round Rock is Different
Round Rock specifically lists window replacement as work that does not require a building permit.
The important catch is that exempt work still has to comply with applicable codes.
That's a good example of why you can't copy a neighbor's experience and assume the same rule applies to your property.
The project may look identical from the outside, but the permitting requirements can be different simply because the house is across a city boundary.
What About Decks?
Decks are one of the easiest exterior projects to underestimate from a permitting standpoint.
A deck isn't just a floor.
Depending on how it is constructed, a deck can involve:
Footings
Structural beams
Joists
Ledger connections
Guardrails
Stairs
Required setbacks
Property-line restrictions
Drainage
Electrical work
Structural loads
In Austin, a small detached deck can fall under the city's residential permit exemptions if it meets all of the applicable conditions, including being no more than 200 square feet, no more than 30 inches above grade, detached from the dwelling, not serving as required egress, and outside a flood hazard area.
That is a much narrower exemption than simply saying:
"Small decks don't need permits."
Round Rock
Round Rock requires a permit for wood decks and covered patios and asks for construction plans, a property survey or plot plan, dimensions, materials, setbacks, and electrical or plumbing information when applicable.
Cedar Park
Cedar Park's deck and patio-cover guidelines require permits for several common situations, including decks that are 30 inches or more above ground, exceed 200 square feet, are attached to a dwelling, serve a required exit door, are multi-level, or cover an existing slab or deck.
Again, the details matter.
Patio Covers Are Usually a Bigger Permit Question
A patio cover may look like a relatively simple addition, but once you add a roof structure, posts, footings, connections, and potentially electrical work, you're dealing with more than a piece of outdoor furniture.
Austin's permitting records include permitted residential projects involving patio covers and decks, and the city's current code also contains specific requirements affecting exterior appendages such as decks, pergolas, and patio covers.
Round Rock requires permits for covered patios and asks for plans showing the structure, materials, property location, setbacks, and applicable electrical or plumbing work.
Leander's current residential deck and patio-cover requirements also state that new wood or concrete decks, additions, covered existing slabs/decks, multi-level decks, and arbors require permits.
So if you're planning a patio cover, don't treat it like a simple cosmetic improvement.
The structure itself is usually the thing that triggers the permitting conversation.
What About Leander?
Leander provides a particularly useful example of how exterior remodeling rules can differ between nearby communities.
The city states that exterior work such as:
Painting
Re-roofing
Replacing siding
Window replacement
does not require a permit.
However, Leander requires permits for additions, accessory structures, and other construction projects, and its deck and patio-cover requirements specifically identify common deck and patio-cover projects that require permitting.
So a homeowner in Leander may be able to replace windows without a permit while a homeowner in Austin may need one for a similar project.
That's not a contradiction.
It's simply a different jurisdiction.
Cedar Park Has Its Own Rules Too
Cedar Park generally requires permits for construction that physically changes or adds structures to a property.
Its published examples include additions, accessory structures, and other projects that change the physical structure.
At the same time, Cedar Park specifically lists non-structural roof covering replacement as work that does not require a permit.
Its deck and patio-cover requirements then add another layer of detail depending on the structure's size, height, attachment, use, and configuration.
This is why a contractor should separate the project into its actual components rather than giving a blanket answer such as "no permit required."
A roof replacement may be exempt.
A new patio cover may not be.
Electrical work may require another permit or inspection.
And a structural modification can change the entire permitting picture.
Georgetown Takes a Different Approach
Georgetown's published fee schedule provides a useful example of how broad its residential permitting categories can be.
The city's miscellaneous residential building permit category includes projects such as:
Remodels
Repairs
Alterations
Additions
Sunrooms
Enclosures
Accessory buildings
Patios
Wood decks
Patio covers
Pergolas
Carports
Garages
It also lists re-roofing without a change in pitch as a separate permit category.
Again, the takeaway isn't that one city is "stricter" than another.
It's that you need to check the rules for the jurisdiction where the house actually sits.
What If You're Outside the City Limits?
This is where things can become even more confusing.
A home may have an Austin mailing address without being inside the City of Austin.
For properties in unincorporated Travis County, the county's Development Services department handles development permitting outside corporate city limits.
Travis County defines development broadly, including changes involving structures, driveways, grading, paving, excavation, and other changes to real estate. The county states that failing to obtain a required permit can result in a Notice of Violation.
The county also provides separate permitting requirements for residential construction and accessory structures.
If you're unsure whether a property is inside a city, county jurisdiction, or another applicable jurisdiction, verify the address before construction begins.
What Happens If You Skip a Required Permit?
Sometimes homeowners think the worst-case scenario is simply paying a permit fee later.
It can be more complicated than that.
If a city discovers work that required a permit but was performed without one, the property owner may have to deal with some combination of:
A code violation
A Notice of Violation
A Stop Work Order
Obtaining permits after the work has already been completed
Additional inspections
Opening finished work so concealed construction can be inspected
Correcting work that doesn't meet current requirements
Removing work that cannot be approved
Delays in completing the project
Additional fees
Austin has documented enforcement cases involving residential construction performed without required permits, with remedies including obtaining the necessary permits. In one example, an improperly located patio cover also had to be removed or brought into compliance through an approved variance.
Travis County similarly states that failure to obtain required permits can result in a Notice of Violation.
The important point is that a permit is not simply paperwork after the fact.
It creates a record that the work was reviewed and inspected under the applicable jurisdiction's requirements.
What Happens When You Sell the House?
This is where an unpermitted project can become a future homeowner's problem.
There isn't a universal rule that says an unpermitted improvement automatically prevents a home from being sold.
But it can create questions during a sale.
For example, a buyer may discover that:
A patio cover isn't reflected in permit records.
A deck was added without the expected inspections.
A room or enclosure was constructed without approval.
A structural alteration has no permit history.
The actual property improvements don't match what a buyer expected from the available records.
Texas' Seller's Disclosure Notice requires sellers of previously occupied single-family residences to disclose information concerning material facts and the physical condition of the property.
That doesn't mean every missing permit automatically has to be described in the same way on every transaction. But if you're selling a home with questionable or unpermitted work, it's worth discussing the situation with your real estate professional and, when appropriate, obtaining legal advice rather than hoping nobody notices.
There can also be practical issues with buyer due diligence, inspections, appraisals, insurance, and lender requirements depending on the property and the improvement.
The safest time to resolve a permitting problem is before you're trying to sell the house.
Can You Get a Permit After the Work Is Already Done?
Sometimes.
But don't assume that an after-the-fact permit is as simple as paying the normal permit fee.
The permitting authority may need to determine what was built, whether it complies with current requirements, and whether portions of the work need to be exposed for inspection.
That's especially important with structural work.
For example, if a deck was built without inspection, the city may need to verify the footing, framing, connections, guardrails, and other components.
If everything is already covered, proving that the work was constructed correctly can become much harder.
This is one reason permitting is usually easier before the work starts.
A Permit Doesn't Mean the Project Is Automatically Code-Compliant
There's another misconception worth clearing up.
Getting a permit isn't the same thing as getting permission to do whatever you want.
The permit is part of a process.
Plans may be reviewed.
Inspections may be required.
Setbacks, structural requirements, drainage, electrical work, fire requirements, energy requirements, and other rules may apply.
And some areas have additional requirements.
Austin's Wildland-Urban Interface rules are a good example. Even when a particular piece of work does not require a building permit, WUI requirements can still apply to work on a property within the applicable WUI areas.
That's why "the city didn't require a permit" and "there are no rules" are two very different statements.
The Four Questions to Ask Before Starting Exterior Work
Before signing a contract or allowing work to begin, ask:
1. What jurisdiction is my property in?
Don't rely only on the mailing address.
2. Does this specific scope of work require a permit?
Be specific.
"Exterior remodeling" isn't a permit category.
"Replace existing asphalt shingles," "replace windows size-for-size," "build a 400-square-foot attached deck," and "construct a covered patio" are very different scopes.
3. Who is responsible for obtaining the permit?
Make sure you know whether the homeowner or contractor is responsible.
And if the contractor says a permit isn't necessary, ask why.
A good contractor should be able to explain the reasoning rather than simply saying, "We don't pull permits."
4. Are there other approvals or inspections involved?
A building permit may not be the only consideration.
Electrical, plumbing, mechanical, drainage, floodplain, fire, zoning, setback, HOA, and other requirements can come into play depending on the project and location.
A Simple Exterior Permit Checklist
Before starting your next project, confirm:
Property

Ten years from now, you may be very glad you did.
The Bottom Line
Permit rules aren't really about whether a project "looks big enough" to need a permit.
They're about what you're changing, where the property is located, and which jurisdiction has authority over the work.
A standard roof replacement might be exempt in one city.
A window replacement might be permitted work in another.
A deck might be exempt if it meets very specific conditions but require a permit if you change its size, height, attachment, or location.
And a patio cover almost always deserves a closer look because you're adding a structure rather than simply replacing an exterior finish.
The easiest mistake is assuming that the rules you heard from a neighbor, another contractor, or a previous project automatically apply to your house.
They may not.
Before construction starts, verify the jurisdiction, verify the scope, and verify the permit requirements.
It's much easier to spend a few minutes confirming the rules than to deal with a violation after the work is already finished.
Frequently Asked Questions
Do I need a permit to replace my roof in Austin?
Not necessarily. Austin exempts certain roof-covering replacements, including asphalt shingle replacement, but there are exceptions, including specific Wildland-Urban Interface situations and work that affects the roof structure.
Do I need a permit to replace windows in Austin?
Austin treats qualifying residential window replacements as permit work, with an express-permit pathway for certain projects such as size-for-size replacements.
Do window replacements require a permit in Round Rock?
Round Rock specifically lists window replacement as work that does not require a building permit, although the work still has to comply with applicable codes.
Does a deck require a permit in Austin?
It depends on the deck. Austin has an exemption for certain small detached decks, but the deck must meet multiple conditions involving size, height, attachment, egress, and flood-hazard location.
Does a patio cover require a permit?
A patio cover should be treated as a permitting question because requirements vary by jurisdiction and the structure may involve structural framing, footings, setbacks, and other requirements. Round Rock, Leander, and Georgetown all publish permitting requirements that cover patio covers.
Can I build a deck first and get the permit later?
Don't assume you can. If a permit was required, completing the work first can make inspection and approval more complicated. The permitting authority may require additional documentation, inspections, or corrective work.
What happens if my contractor says I don't need a permit?
Ask the contractor to explain which jurisdictional exemption applies to your specific scope. You can also contact the local building department directly. Permit requirements are ultimately determined by the applicable jurisdiction, not by a contractor's preference.
Can unpermitted work stop me from selling my house?
Not necessarily, but it can create complications during a sale. Buyers, inspectors, appraisers, lenders, insurers, and real estate professionals may have questions about work that doesn't have the expected permit or inspection history.
Do I have to disclose unpermitted work when selling?
Texas sellers of previously occupied single-family residences have disclosure obligations concerning material facts and physical condition. Whether and how a particular permitting issue must be disclosed depends on the circumstances, so homeowners with significant unpermitted work should discuss it with their real estate professional and, when appropriate, an attorney.
Does a permit guarantee that my project is code-compliant?
No. A permit is part of the approval and inspection process. The completed work still has to comply with applicable codes, ordinances, and approved plans.
Does living in Austin mean Austin handles my permit?
Not necessarily. Verify whether the property is actually inside the City of Austin or in another jurisdiction. Properties outside corporate city limits may fall under county or other jurisdictional requirements.
What should I do if I discover that an old improvement was never permitted?
Don't immediately assume the structure has to be removed. Start by determining what jurisdiction applies, what was built, when it was built, and whether permit records exist. The appropriate building department can explain the process for resolving an existing issue.
