A roof makes it a structure
An open patio slab sitting on the ground is not a permit issue anywhere in Texas. The moment you put posts and a roof over it, you have built a structure, and structures get reviewed. That is the whole principle behind every rule on this page.
The bigger dividing line is whether it touches your house. An attached cover hangs off a ledger board and pushes load into your home's framing and foundation. That is why cities are stricter about attached covers than freestanding ones, and why an engineer usually has to sign the plans.
What DFW cities look for
- Attached covers need a permit essentially everywhere. Expect a building permit and, in most cities, structural plans sealed by a Texas licensed engineer.
- Freestanding is where cities differ. Dallas exempts detached covers under 200 square feet behind the front setback with no utilities. Fort Worth has no size based exemption and permits patio covers regardless.
- Setbacks apply. How close the structure can sit to a property line or easement is a zoning question, separate from the building permit, and it can change the design.
- Adding power adds permits. Fans, lights, or a motor for a louvered roof pull in an electrical permit and licensed work on top of the building permit.
- Material rules exist. Dallas, for instance, does not allow unpainted wood, canvas, or corrugated metal as a finished patio cover material.
- Your HOA is a separate approval. A city permit says nothing about what your HOA allows. Both have to clear, and the HOA is often the slower one.
Rules and review times vary city to city across the metroplex and they change. Treat this page as the shape of what to expect, then confirm the current requirement with your own building department before anything gets built. A contractor who handles the permit for you should be able to tell you exactly which ones your job needs.
