By law, when you advertise, solicit bids or offer to perform work, you must always include your contractor registration number. This includes business cards, Yellow Page ads, newspaper ads, estimates and bid proposals.
General and specialty contractors must provide a contractor's surety bond (88 KB PDF). Surety bonds are available through a bonding company or insurance agency. Premiums vary with each company, as do the requirements for being bonded.
The bond must include the bond number and exact business name.
The alternative to a bond is an assigned bank account. An Assignment of Account, must be on this form. (Also available at L&I local offices.) You may post the required amount in the form of cash, a certificate of deposit, time deposit, or money market account in a bank, savings and loan association or credit union within Washington state.
NOTE: Originals of your bond and insurance will be required to complete your registration.
You must provide this notice to consumers for all residential jobs of $1,000 or more and for commercial projects of $1,000 to $60,000.
Understand your responsibilities for the safety of your employees and/or sub-contractors.
