Is a permit required to install a new sink, toilet, bathtub, or hot water heater?
A plumbing permit must be obtained prior to commencement of all new plumbing work and most replacement projects. Replacement of an existing sink or toilet, for example, does not require a permit providing that no modification to the water or sewer connections is made. Homeowners desiring to do his/her own minor plumbing work must provide proof of residences. Owners of multiple properties cannot obtain permits for homes that are not their primary residences. Persons renting a home cannot obtain permits for work in the rental property.
