New building permits in Mercer Island, Washington indicate upcoming construction projects. Contractors can identify subcontracting opportunities by monitoring recently issued permits for residential renovations, commercial buildouts, and new construction. Early outreach to permit holders often results in higher close rates before projects go to competitive bid.
Mercer Island, Washington processes thousands of building permits covering residential construction, commercial buildouts, renovations, and specialty trade work. PermitGrab tracks 905+ Mercer Island building permits — updated daily from official city sources.
Every new construction project in Mercer Island requires a building permit before work can begin. These public records include the project address, scope of work, estimated cost, and often the general contractor's name — making them valuable leads for subcontractors looking for new projects in Mercer Island.
HVAC contractors, electricians, plumbers, and roofers in Mercer Island use building permit data to find projects before they hit traditional lead services. When a new commercial buildout or residential renovation permit is filed, it signals upcoming work that needs subcontractors.
Instead of competing for shared leads on HomeAdvisor or Angi, contractors who monitor Mercer Island building permits can reach out to general contractors the day a permit is issued — before anyone else calls. This first-mover advantage leads to higher close rates and better project selection.
PermitGrab sends daily email alerts filtered by trade, so Mercer Island electrical contractors only see electrical permits, HVAC contractors only see mechanical permits, and so on.

Search any competitor's name and see every job they pulled in Mercer Island — where they're working, what they're charging the city in declared value, and which neighborhoods they own. Pitch the follow-on work at each address.
Code violations matched to property owners. An owner facing a citation is the warmest restoration, repair, or wholesale-offer lead there is — and no marketplace sells this list.
