Which backyard projects usually need a permit
Every city in the metro sets its own rules, so the office below is the final word for your address. As a starting point, these are the projects cities in North Texas most often review before work begins:
- Pools and spas, including the fence or barrier around them. Many cities treat the barrier as its own permit.
- Patio covers, pergolas and enclosures that attach to the house or add a roof.
- Sunrooms and room additions, which are reviewed as new living space.
- Outdoor kitchens with new gas lines, electrical circuits or plumbing.
- Windows, doors and siding in some cities, especially where the opening size changes.
Your HOA is a separate approval. Most HOAs want drawings before the city does, so ask them first.
Where to apply in each DFW city
These are the cities we are asked about most. Each link goes to the city’s own permit page, and we checked every one on the city’s website on September 16, 2026. Rules and fees change, so confirm with the city before you apply.
