What Washington rules say
- Most electrical work in Washington needs a permit and an inspection. (source: Washington State Department of Labor and Industries)
- If you hire an electrical contractor, the contractor buys the permit for its own work. (source: Washington State Department of Labor and Industries)
- If someone you hired asks you to buy the permit for them, that is illegal and the permit is not valid. (source: Washington State Department of Labor and Industries)
- You must ask for inspection before covering the work and no later than 3 business days after finishing it, or 1 business day after power is turned on, whichever is first. (source: Washington State Department of Labor and Industries)
- Like for like swaps of up to five switches, dimmers, outlets or thermostats do not need a permit. (source: Washington State Department of Labor and Industries)
- Owners may do electrical work on their own home without a license, except on a new building meant for rent, sale or lease. (source: Washington State Legislature)
- That owner exemption also does not apply to property offered for sale within 12 months of buying it. (source: Washington State Legislature)
- Some cities, and the Tacoma Power service area, issue their own permits; everywhere else Labor and Industries handles them. (source: Washington State Department of Labor and Industries)
- Real estate agents, property managers and relatives cannot buy an owner permit for you. (source: Washington State Department of Labor and Industries)
