Before the new build
Demolishing a house in Bellevue: permits and sequencing
Demolition is its own project. Utility disconnections, erosion control, right-of-way work, hazardous materials, and the new-house schedule all need to line up before the excavator arrives.
Reviewed against official sources · August 2026Confirm whether demolition is separate
Bellevue’s demolition permit covers removal of all or part of a permanent structure. Some new-house permits include demolition in the combined scope, so confirm the intended permit path before filing duplicate or conflicting applications.
Map the permits around the demolition
- Demolition drawings and a construction stormwater pollution prevention plan.
- Water and sewer disconnection documentation.
- A separate right-of-way permit for utility capping, fencing, temporary access, or other work in the public right-of-way.
- Possible SEPA review depending on the project.
- The later building, grading, utility, and tree approvals for the replacement project.
Do not assume the demolition permit removes trees
Bellevue explicitly says a demolition-only permit does not authorize tree removal. Coordinate retained-tree protection and any separate tree approval before staging equipment or disturbing roots.
Plan waste and hazardous-material handling
Ask the demolition contractor for the disposal and recycling plan, utility shutoff sequence, and responsibility for asbestos, lead, tanks, or other suspect materials. King County maintains current construction-and-demolition material requirements and facility information.
Tie demolition to the replacement schedule
Confirm when demolition may begin, what must remain accessible for reviewers or surveyors, and whether financing or insurance requires the replacement permit first. Avoid creating a vacant site months before the next permit is ready.
Action plan
Sequence demolition safely
- 1
Confirm whether demolition is a separate BE permit or included in the replacement building permit.
- 2
Coordinate water, sewer, power, gas, and communications disconnections in writing.
- 3
Map temporary access, fencing, utility caps, and other public-right-of-way work.

Keep tree removal and retained-tree protection under the correct separate approval.
- 5
Align demolition release with financing, insurance, waste handling, and the replacement-permit schedule.
