A patio cover or pergola over a deck turns a deck you avoid in July into one you use, but the posts need their own solid base, not just the deck boards.

Pergola or Solid Cover
A pergola has open rafters and slats. It breaks up the sun and looks great with a vine on it, but it lets rain through. A solid cover has a real roof. It blocks sun and rain, and it can carry a fan or lights. A solid cover often ties into the roof of the house, so the roofline has to allow it.
Why the Posts Matter
A cover or pergola puts its weight on a few posts. Those posts need a base that reaches solid ground. Setting them on top of deck boards is not enough. On a new deck we plan the cover posts from the start. On an old deck we may run new posts down through it.
Permits for Covers
Cedar Park lists gazebos and arbors as accessory structures that need permits. Its residential permits page also has a deck and patio cover guide and a checklist. Plan on a permit for a cover and check the details with the city. See our permit guide.
Questions
Does a pergola need a permit in Cedar Park?
The city lists gazebos and arbors as structures that need permits, and it posts a deck and patio cover guide. Check your exact plan with the permit office.
Can you add a cover to my existing deck?
Often, yes. The cover posts need their own solid base, so we check the deck and the ground first.
Will a cover make my house darker?
A solid cover shades the windows under it. A pergola lets more light through. We can talk through both.
