Licenses & Permits in Washington
General Business License
Washington State requires most businesses to obtain a Unified Business Identifier (UBI) through the Business Licensing Service (BLS) of the Department of Revenue. Washington has no state income tax, but does have a Business and Occupation (B&O) tax applied to gross receipts, which is unique among US states. Additionally, businesses must register for the B&O tax and any applicable retail sales tax. Many cities require a separate city business license endorsed onto the state license through a streamlined endorsement system.

Next Steps to Launch Your Demolition Company
- 1
Form your LLC or corporation in Washington — demolition contractors face major injury and environmental liability (filing fee: $200)
- 2
Obtain your Washington demolition contractor license — most states require a specialty or general contractor license for demolition work
- 3
Complete OSHA 30-Hour Construction Safety training and obtain your OSHA Competent Person designation for demolition operations
- 4
Conduct or obtain EPA asbestos surveys before demolishing older structures — required by EPA NESHAP regulations (https://www.epa.gov/asbestos/asbestos-neshap); failure risks significant fines
- 5
Get a contractor surety bond and general liability insurance — bond requirements vary by state and the GL premium is typically a meaningful four-to-low-five-figure annual cost; both are required by municipalities and general contractors
- 6
Obtain EPA RRP (Renovation, Repair and Painting) certification (https://www.epa.gov/lead/renovation-repair-and-painting-program) if working on older structures that may contain lead paint
- 7
Register with your Washington environmental agency for hazardous waste hauling if removing asbestos, lead, or contaminated materials
- 8
Establish relationships with salvage yards and recycling facilities in Washington — separating metals, concrete, and wood reduces disposal costs
