When is a Commercial Building Permit Required?

A commercial building permit from the Town of Cary is required anytime a new tenant moves into a space or if any plumbing, electrical, mechanical, sprinkler, fire alarm or structural changes are made to the building.

In cases where a new tenant moves into a space, these permits are classified as either a change of tenant (moving into a space that was previously permitted for the same building occupancy type, such as Business to Business) or a change of occupancy (moving into a space that was previously approved for a different building code occupancy type, such as from a Business use to an Educational use).

Please review our Commercial Projects Plan Submittal Guide for information on how to apply for a commercial building permit. For more information, please visit the Chamber of Commerce/Town of Cary Guide to Starting a Business, or call 311 or (919) 469-4046.

Obtaining a Commercial Building Permit

Commercial building permits are applied for using IDT, our electronic plan review system. During the building permit plan review process, contractors’ licenses will be verified, fees will be calculated, and plans will be reviewed by building, plumbing, electrical, mechanical, and fire plans examiners, as well as Wake County Environmental Services, Utilities Pre-Treatment, and/or any other applicable departments as required.  

If you are planning to install an irrigation system as part of your commercial project, please be advised that this requires a separate permit application and incurs irrigation development fees based on the square footage of irrigated area.  

Any problems found during the process are communicated back to the applicant via email.
