Woodbury uses a combination permit. Separate permits will only be required on jobs where there is no related building permit. Check your building permit to see if it already includes the plumbing permit fee.
A Plumbing Permit is required for all changes to plumbing, including installation or replacement of a water softener, water heater, or back flow preventer for a lawn irrigation system. For water heater replacements, a fresh air intake must be installed if not currently existing.
Plumbers must have a current state license and bond on file with the city.
