Inside the city of Riverside, larger drywall, electrical and plumbing repairs can require permits from the City of Riverside Building and Safety Division. Homes in other cities, such as Moreno Valley, Corona or Jurupa Valley, follow the rules of that city or county.
California requires trauma scene waste management practitioners to register with the state. Ask for proof of registration and insurance.
