Plumbing Leads from Building Permits
Plumbers find leads in building permits by watching plumbing permits (water heaters, repipes, sewer and water lines, fixtures) and the projects that always need a plumber: kitchen and bath remodels, additions, ADUs and new construction.

Permit descriptions that signal plumbing work
Water heater, tankless, repipe, sewer line, water service, gas line, backflow, fixture replacement and drain. Many cities issue plumbing as its own permit type, which makes filtering easy.
Where the bigger jobs hide
Kitchen and bath remodels, additions, basement finishes and accessory dwelling units all need rough-in and finish plumbing. New construction permits show which builders are active and need reliable plumbing subs.
How to follow up
Water heater and repipe permits pulled by other plumbers often mean the home is older, a good fit for a whole-house inspection or a maintenance plan. For remodel permits, reach the general contractor of record as well as the owner.
