ELECTRICAL
Electrical Requirements :
A separate electrical panel (subpanel) is required for a detached two-car garage .
- The National Electrical Code (NEC), requires a subpanel in a detached building to provide the necessary circuits safely and legally. A multi-wire branch circuit can be considered a single branch circuit for this purpose.
- A subpanel with a main breaker, Grounding electrode system installed
- One 20-amp, 120-volt circuit: The NEC requires at least one 120-volt, 20-amp circuit with GFCI (Ground-Fault Circuit Interrupter) protection for receptacles in garages. This circuit must be dedicated and cannot have other outlets connected to it.
- At least one receptacle per car bay: You'll need at least one receptacle outlet in each vehicle bay of the garage, and these must be GFCI protected.
- Switched lighting outlet: At least one switched lighting outlet is required in the garage, and it should not be connected to the dedicated 20-amp circuit.
- Arc-fault circuit interrupter (AFCI) protection:
- Garages in WA require protection by an AFCI device, typically a circuit breaker. AFCIs are generally not compatible with multi-wire branch circuits.
- EV charger installation: will require a dedicated 240V circuit.

insulation and drywall
Insulation
Based on the Washington State Energy Code, whether you're required to insulate garage depends on whether the garage will be heated or not.
Heated Garages: If you plan to heat your garage, it must be fully insulated according to the energy code requirements for conditioned spaces. This includes insulating the walls as well as the ceiling and the perimeter of the slab. The minimum ceiling insulation R-value for heated garages in Climate Zones 0-4 (Sammamish) is R-19
Unheated Garages: While not explicitly mandated by the code, it is generally recommended to insulate an unheated garage
Drywall:
5/8" Type X drywall ( "XP" ) By Code, includes Table R302.6 which outlines the dwelling-garage fire separation requirements, confirming the need for 5/8-inch Type X drywall in ceilings under habitable rooms above the garage. Place, Patch, Paint
