Permit Drawings for Texas Home Projects, Ready in About an Hour

Start here, because the answer is not always yes and nobody wants to pay for drawings they did not need.

In Houston, ground-level uncovered patios do not need a building permit. Decks are also exempt if they are under 200 square feet, no more than 30 inches above grade, and not attached to the house.

Add a roof, and everything changes. Houston requires a permit for every patio cover, attached or freestanding.

Fort Worth requires a permit for all patio covers with no size-based exemption for detached ones, which is different from Dallas. A freestanding accessory structure under 120 square feet used for storage may be exempt in Fort Worth, but that exemption does not extend to covered patio structures.

The pattern across Texas is consistent: a permanent roof turns a patio into a regulated structure. Once wind load and structural connections are involved, your city wants drawings.

Most Texas departments want the same core documents for a residential outdoor project:

• A site plan showing your lot, property lines, existing structures, and the new structure with distances to each line
• A framing plan showing member sizes and spacing
• Foundation and footing details with depth and diameter called out
• Elevations showing height and how the structure meets grade
• Connection details, especially how a ledger attaches to the house
• Code compliance notes specific to your city's adopted amendments

Requirements are scaled and dimensioned, drawn clearly enough that a reviewer can check numbers without guessing. Some cities also want your lot size and the square footage of every existing structure listed on the sheet.

A site plan is the bird's-eye view of your property with your new structure drawn in place, to scale, with measured distances to every property line.

It is the sheet reviewers check first, because it answers the question they care most about: does this thing sit where it is allowed to sit?

Setback rules control how close a structure can be to a fence or property line. They exist to prevent neighbor disputes and to maintain fire separation. A patio cover that looks small can still land inside a setback.

This is where guesswork fails. If your site plan is drawn from memory instead of your survey, the distances will be wrong, and a reviewer will catch it.

NALO builds your site plan from your uploaded survey document and your property photos, so the structure is placed against your real lot lines rather than an estimate.

Longer than most people plan for, and the drawings are only one part.

Houston plan review queues typically run two to four weeks for anything beyond a trivial scope. Fort Worth standard review takes about one to two weeks for straightforward residential work.

Then add the front end. Waiting on drawings adds four days to two weeks before you can even submit.

That front end is the part NALO removes. Your drawings are ready in about an hour, so your review clock starts the same day instead of next week.

Three separate costs, and people usually only budget for one.

City permit fees. Houston patio cover permits generally run $100 to $500. Fort Worth residential permit fees start around $112 and scale with complexity. Some cities add a plan review fee on top, such as The Colony's $50 non-refundable review fee paid at application.

Drawings. $800 to $3,000 from a typical engineer engagement, or $119 with NALO.

Rejection costs. Not a line item, but real. One avoidable correction in Houston can cost you another two to four weeks.

Rarely for complicated reasons. The repeat offenders:

• Structure placed inside a required setback
• Footing depth missing or too shallow for local soil
• No detail showing how the ledger attaches to the house
• Height over the local limit
• Missing sheets from the city's required list
• Lot dimensions or existing square footage left off the site plan

NALO checks each of these while you are answering questions. If something breaks a rule, you get told the specific rule and the specific fix before any drawing is generated.

Catching it there costs you thirty seconds. Catching it at the counter costs you a review cycle.

• Step 1: Enter your address. Your city's code loads right away. Setbacks, height limits, wind load, and the required sheet list.
• Step 2: Answer plain questions. Dimensions, materials, how it attaches. No technical vocabulary. A couple of minutes.
• Step 3: Upload photos and your survey. These place your structure accurately on the site plan.
• Step 4: Download and submit. A 10-sheet PDF drawn to NCS and AIA standards at tabloid size, which is the format Texas plan reviewers open every day. You submit it to your city and pay their fee.

City approval and HOA approval are two different gates, and clearing one does not clear the other.

Many Texas HOAs require architectural review before any construction starts. Some prohibit metal roofing or restrict colors so the structure blends with the house.

Permit drawings answer the city's questions. They rarely answer an HOA board's question, which is usually "what will this look like from the street?"

That is what the 3D render is for. Upload your photos, describe the project, and get a photorealistic image of the finished space. It tends to move an HOA conversation faster than a framing plan does.

Being direct here protects you.

NALO is a software tool that produces construction documents for residential projects falling inside the Texas Occupations Code Section 1001.056 exemption. That generally covers residential structures under 5,000 square feet with no clear span greater than 24 feet on the narrow side.

NALO is not a registered engineering firm. We do not provide sealed drawings or professional engineering services.

What that means for you: if your project qualifies, no seal is needed, and NALO drawings are built for that case. If it does not qualify, you need a licensed Texas engineer, and the tool tells you before you pay.

Some cities require a seal even on smaller work. The Colony, for example, requires an engineer seal on foundation plans and on patio cover plans when the cover attaches to the primary structure. Austin requires structural drawings for covered patios to be sealed by a Texas-registered architect or certified building designer when the structure exceeds 20 feet in height or involves a second story.

Always confirm your project with your building department before you build.

• Spans over 24 feet between supports
• Projects over 5,000 square feet
• Coastal counties needing windstorm certification
• Slab design on expansive soil
• Altering a load-bearing wall or existing foundation
• Any city that requires a sealed drawing for your specific project type

We would rather send you to the right professional than sell you drawings your city will reject.

• Attached and freestanding patio covers
• Decks, including elevated decks
• Pergolas and shade structures
• Accessory dwelling units within the size limits
• Carports

Outside these, the tool flags it at the address step.
