Sumner Permits

Building Permits and Plans in Sumner

Our office is on 64th St E in Sumner, so this is home turf. We handle plans, energy forms, and permits for ADUs, additions, remodels, garages, and new homes.

Sumner address, which office reviews it

A Sumner mailing address does not always mean a City of Sumner permit. Some parcels fall under Pierce County. We look up the parcel first and tell you which office you are dealing with.

What we see around Sumner

  • Older homes that need as-built drawings
  • Valley and floodplain checks, best done early
  • Growing interest in ADUs
  • Shops and garages

What Build Sherpas does here

  • ADU and DADU plans
  • Home addition plans
  • Remodel plans
  • Energy code forms
  • Permit runner
  • Permits for work already built
  • Build consulting

We do not build and we do not engineer or stamp. Where engineering is required, our sister firm Dow Engineering PLLC, in the same office, handles it. Air leakage tests come from WA Blower Door.
