Summary
Operating as a concrete contractor in Spokane, Washington requires both state and local licensing compliance. You must obtain a Specialty Contractor License from Washington State L&I, which involves passing exams, proving experience, and maintaining bonding and insurance requirements. The City of Spokane requires a separate business license and building permits for most concrete work. The permitting process is generally straightforward but requires advance planning, especially for commercial projects that may need additional engineering review. Insurance requirements are substantial, with most work requiring $1 million in general liability coverage beyond the state minimums. The local market is competitive but steady, with residential and commercial development driving consistent demand for quality concrete work.
License Requirements
Washington State requires concrete contractors to hold a Specialty Contractor License from the Washington State Department of Labor & Industries (L&I). This requires passing the business law exam and trade-specific exam, providing proof of 4 years experience or 2 years experience plus approved education, and maintaining a $12,000 surety bond. The City of Spokane requires a separate business license through the Business License Division. Licenses must be renewed every two years with continuing education requirements (8 hours for specialty contractors). Contractors performing work over $1,000 must be registered with L&I.
Permit Requirements
Building permits are required through the City of Spokane Building Services Department for most concrete work including foundations, driveways, sidewalks, patios, and structural concrete. Permit applications require approved plans, contractor licensing verification, and fees ranging from $85-$500+ depending on project scope. Commercial projects require additional review and may need structural engineer approval. Typical permit processing takes 2-3 weeks for residential and 3-6 weeks for commercial projects. Right-of-way permits are needed for sidewalk work adjacent to public property.
Insurance Requirements
Washington State requires minimum $50,000 general liability insurance and workers' compensation coverage through L&I or approved self-insurance. Most clients and the City of Spokane require $1 million general liability coverage. Professional liability insurance is recommended for structural concrete work. Contractors must maintain a $12,000 surety bond filed with L&I. Vehicle insurance meeting state minimums is required for all work vehicles. Umbrella policies are recommended for larger commercial projects.
Typical Cost Ranges
Residential concrete work in Spokane typically ranges: basic concrete slabs $4-8 per sq ft, decorative concrete $8-15 per sq ft, driveways $6-12 per sq ft, foundations $8-15 per sq ft, and sidewalks $5-10 per sq ft. Commercial projects range $10-25+ per sq ft depending on complexity. Permit fees add $100-500+ to project costs. Material costs have increased 15-20% in recent years due to regional supply chain factors.
