While-You-Wait Plan Review & Permits

"While-You-Wait" plan review is a service Public Works provides that allows our customers to apply for a simple permit and wait while the plans are reviewed. The review of the plans for Residential Construction is performed on a first come first served basis. On qualifying projects, the applicant can apply for and receive the permit in a short period of time. The review of the plans for most Commercial Construction is performed by appointment only.

The "While-You-Wait" service is conducted at our main office (Clayton) between the hours of 8:00 a.m. until 3:30 p.m. This service is also available to our residential customers from our Satellite Offices. For More information see our flyer titled Residential While-You-Wait Services Available at Satellite Offices.
