Choosing and working with a contractor

Licenses and registrations

Property owners should make sure that contractors have required licenses or registrations before hiring them.


Property owners should ask contractors for references and do additional research. The recommendations from the Attorney General’s Office include:

  • Checking contractors’ references.
  • Getting more than one bid for the job.
  • Checking for complaints filed with the Better Business Bureau.


Once you hire a contractor, make sure that they have the required permits from L&I and have posted those permits on your property before they begin work.
