Deck Builder in Bellevue
Bellevue handles decks through the same permit it uses for small home additions, and that includes rebuilding the framing of a deck you already have. Here is what the city asks for before the first footing goes in, plus where to check typical Eastside prices.

Found rot in the joists or beams? In Bellevue that repair needs a permit, not only a brand-new deck: the city's single-family addition permit covers building a deck or deck with spa and the repair or replacement of existing deck structural framing. Plan for that paperwork before the old framing comes apart.

Expect engineering paperwork on a Bellevue deck. The application lists a structural plan and structural and lateral calculations, next to a site plan and a stormwater site plan, so ask the deck pro whether preparing those is part of the written quote.

The stormwater part is usually the lighter version: Bellevue accepts a short-form construction stormwater pollution prevention plan for projects with less than 7,000 square feet of clearing and less than 100 yards of grading. A typical backyard deck disturbs far less ground than either limit.
