Plumbing Permits and Inspections
A residential plumbing permit is required to add, replace, repair or alter water service, drains, water lines, gas lines, sewer lines, water heaters, sewage disposal systems and other plumbing fixtures and appliances. You are required to apply for a plumbing permit before any work can begin. Plumbing permits are based upon the number and types of fixtures, sewers , drains, and water service piping that are included in the project.  

For information concerning the cost of a plumbing permit, call the Permit Counter at 949-724-6313. Additional costs may apply if the project involves establishing new water or sewer service, or adding to existing service. Inspection costs are included in the permit fee. The inspections are mandatory before a Certificate of Occupancy can be issued.

Inspections may be requested through our automated inspection request line by calling 949-724-6501, or by calling our inspection desk at 949-724-6396. Inspection request information may be found here.  

When requesting an inspection, please give relevant permit numbers, the time, date and place you would like the inspection, and the name of the contractor. Allow a minimum of 1 working day from the time of your request for a plumbing inspector to visit your site. 

After the inspection has been completed, a sticker will be left in a central location on the premises that indicate the date of inspection, and whether or not the work passed.
