Bellevue Washington Trade, Solar, and EV Permit Guide

Bellevue issues electrical, mechanical, and plumbing permits as stand-alone permits or as part of construction projects, with EV chargers, solar panels, HVAC, generators, gas lines, and water heaters often requiring trade review.

Permit takeaway

Bellevue requires electrical permits for adding or moving circuits, changing service panels, generators, branch circuits, EV charging stations, solar panels, and similar work beyond maintenance.

Zoning and placement

Solar, generator, HVAC, and exterior equipment locations can raise placement, noise, screening, and building-project coordination questions.

Building and trade review

Mechanical permits are required for installing or replacing fossil-fuel piping and appliances and HVAC equipment, while plumbing permits cover concealed piping and many water-service or fixture changes.

Call before applying when
