Question 1

Does a Sammamish deck project need a permit?

Accepted Answer

Sammamish lists new deck construction and deck repair among projects that may require a permit. The City determines the required application, plans, review, and inspection path from the address and final scope before construction begins.

Question 2

What does Sammamish's 30-inch deck threshold mean?

Accepted Answer

Sammamish Municipal Code requires guards where an open deck walking surface is more than 30 inches above the floor or grade below. That is a guard and railing planning threshold; it is not an automatic deck-permit exemption.

Question 3

How can critical areas and slope affect a Sammamish deck?

Accepted Answer

Sammamish identifies wetlands, streams, habitat, landslide areas, steep slopes, and erosion-prone areas among its critical-area considerations. The deck checklist requires a Critical Areas Affidavit, and a City-required study may change the development-review path when critical areas are present. Site conditions must be reviewed for the actual property.

Question 4

How do setbacks affect a Sammamish deck layout?

Accepted Answer

Setback and allowable-placement questions are property-specific. Sammamish's deck checklist calls for a site plan on new or enlarged decks, so property lines, zoning, sensitive areas, drainage, slope, and the proposed deck footprint should be confirmed for the address before final dimensions are committed.

Question 5

How are deck permits and inspections handled in Sammamish?

Accepted Answer

Sammamish uses MyBuildingPermit.com for applications, documents, permit status, and inspection requests. For work under a current City permit, the Building Division performs sequential inspections and says work should not be covered or enclosed before an approved inspection.
