Electrical, mechanical, and plumbing
Bellevue electrical, mechanical, and plumbing permits for homeowners
A project that looks like one installation can require more than one permit. An air conditioner, for example, can involve both mechanical and electrical work, while fire protection remains separate from ordinary mechanical scope.

List every system being changed
- Electrical service, panels, generators, circuits, EV charging, appliances, and solar.
- Heating, cooling, ventilation, gas piping, fireplaces, and equipment replacement.
- Water, waste, vents, fixtures, irrigation backflow, and water heaters.
- Fire sprinklers or alarms, which follow separate fire-permit paths.
Check what the main building permit includes
Bellevue’s combined residential permits can include electrical, mechanical, and plumbing scope, but important exceptions remain, including temporary power and fire protection. Stand-alone equipment work uses its own trade permit. Confirm the permit list rather than assuming the general contractor handles every application.
Match applicant, contractor, and inspection
Record who is applying, the contractor license and Bellevue business-license information, the permit number, and who schedules each inspection. A permit purchased by one party can still be forgotten when another party assumes it was closed.
Watch for plan review
Some complex or larger installations need plans rather than an over-the-counter permit. Electrical service changes, solar, engineered mechanical systems, structural penetrations, and unusual equipment are good reasons to confirm requirements before ordering.
Close the trade permits
Make the final payment conditional on required finals being approved and provide the homeowner with permit numbers, inspection results, equipment manuals, warranties, and commissioning records.
Practical homeowner guide
Coordinate the systems before each trade permits its own slice
Electrical, mechanical, and plumbing permits can move independently, but their equipment, routes, clearances, penetrations, energy requirements, and inspections share the same building.
Part 1 · Electrical
Service and connected loads
Plan panels, circuits, EV charging, generators, solar, temporary power, controls, and utility service. Confirm major equipment requirements before finalizing the electrical design.
Part 2 · Mechanical
Equipment, air, and fuel
Coordinate HVAC, ducts, ventilation, exhaust, heat pumps, gas piping, fireplaces, combustion air, clearances, and condensate with structure and architecture.
Part 3 · Plumbing
Supply, waste, and vent
Confirm fixtures, water heating, service size, waste and vent routing, side sewer conditions, and penetrations. Protect required slopes and access before framing is fixed.
Common questions
What homeowners usually ask
Can a Bellevue trade permit be issued without plan review?
Some straightforward scopes may use a no-plan-review path, while larger or specialized systems require documents and review. Match the actual equipment and work to the current city permit category.
Why might one appliance need more than one permit?
Equipment can combine power, mechanical installation, gas, water, venting, or drainage. For example, HVAC or water-heating work may involve more than one trade and multiple inspections.
Who should track final approval?
The general contractor or owner should maintain the permit matrix even when each trade pulls its own permit. Confirm rough and final approvals for every record before concealment, occupancy, or final payment.
