Puyallup addresses can fall in the City of Puyallup or in unincorporated Pierce County, including South Hill. We look up the parcel first and tell you which office reviews your ADU.
Check the lot first
Zone, setbacks, size, parking, sewer or septic, and floodplain all matter. See Site Feasibility.
What we draw
We handle the energy code forms, and bring in Dow Engineering PLLC when structural work is needed. Building it yourself? See Build Consulting. Air leakage tests come from WA Blower Door. See also Puyallup Permits and ADU and DADU Plans.
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.
