Things to consider when hiring and working with contractor(s)…
When hiring a contractor it is a good idea to get a written estimate, which includes the specific work
to be performed, the time frame involved, and your cost.
When making a payment request a detailed receipt of the work and materials you are paying for.
It is also a good idea to request a waiver of lien in consideration for final and full payment. A final
waiver of lien waives and releases the contractor’s right to claim a lien for labor, services, or
materials, furnished for the project.
Issuance of a permit does not exempt you from the rules and regulations of your Home Owners
Association (HOA). If your HOA requires you to have their approval prior to filing for a permit and
you have not done so, please contact them immediately before commencing work on this project.
