US requirements vary by state, county and municipality. Local building departments and licensing boards are the starting point for project-specific answers.
Verify local permits and licences
Structural, electrical, plumbing, mechanical and gas work may require separate permits and inspections. Ask who pulls each permit and verify the contractor’s status with the relevant authority.
Consider pre-1978 lead requirements
The US EPA Renovation, Repair and Painting program addresses work that disturbs lead-based paint in pre-1978 housing and child-occupied facilities. Contractors may need certification and lead-safe practices.
Use model-specific appliance information
National electrical and product standards do not eliminate local amendments or installation instructions. Coordinate the exact appliance with qualified trades.
Research current incentives locally
Energy-efficiency rebates and tax rules change. Use official federal, state and utility sources rather than old blog summaries.
