Basement permit in Gilbert, AZ
Yes — you need a permit for basement work in Gilbert.
Plan on a building permit to finish a basement or convert it into living space. This creates habitable area with electrical, egress and often mechanical/plumbing work. Gilbert's adopted permit-exempt list (IRC R105.2) exempts only a detached non-habitable accessory structure of 200 square feet or less, so basement finishing is not exempt.

How to pull the permit
- Put together a site plan showing where the work goes, with dimensions.
- Apply through the Gilbert building department.
- Pay the permit fee when the permit is issued. Work done before that isn't covered.
- 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
If you do the work without a required permit, the town first sends a written notice giving you time to comply. If you miss that deadline you can be fined up to $250 for a first violation, $500 for a second, and $1,000 for the third and any later one, with each day counted as a separate offense. After a third violation you can face up to six months in jail.

Does unpermitted work cause problems when selling the house?
