Permit Requirements

Deck permit in Plano, TX

It depends — some deck work in Plano needs a permit, some doesn't.

A small ground-level deck can skip the permit, but only if it meets every limit at once: no more than 200 square feet, no more than 30 inches above grade at any point, not attached to the house or townhouse, and not serving a required exit door. Miss any one of those and you need a permit. Most raised or attached decks need one.

How to pull the permit

  1. Put together a site plan showing where the work goes, with dimensions.
  2. Apply through the Plano building department.
  3. Pay the permit fee when the permit is issued. Work done before that isn't covered.
  4. Book each inspection listed on the permit as the job reaches that stage.

Either of you can pull it. When a contractor does the work, it is normally their job.

If you skip it

Building without a required permit is a violation, and every day it continues counts as a separate offense.

Rules stop at the city line. If your lot is near a boundary, or you work across several towns, this is where they differ.

Questions people ask

My deck is right at the limit. Does that count?

The exemption has to fit exactly — if the code says a size or height, being at or under it keeps you exempt, and going a single inch over doesn't. When you're close to the line, measure before you buy materials, and call the department if the number is borderline.

I already built it without a permit. What now?

Plano can issue a stop-work order and require you to apply after the fact, sometimes with an extra fee. Work that was covered up may have to be opened for inspection. Full walkthrough here.

Does unpermitted work cause problems when selling the house?

Often, yes. A buyer's inspector or the title company may flag it, and lenders can balk at financing a home with open or missing permits. What to do about it.
