What's New!

We have recently upgraded our Request For Service management system. William Lyon Homes along with SiteOne Services, have created a homeowner specific web-site where you can manage the Warranty requests for your home.

Utilizing your SiteOne homeowner web-site you can:

  • Create and submit warranty requests electronically.
  • Monitor the progress of warranty requests.
  • Electronically sign-off warranty requests.
  • View project and lot specific documents.

New homeowners will receive an email from our Warranty Coordinator containing your new SiteOne Username and Password, along with other information about SiteOne. If you are an existing homeowner and do not currently have a username and password for SiteOne, please Email our Warranty Service Department for your area @ Humberto.Lumbreras@lyonhomes.com and our Coordinator will help you with the process.

Thank you!
William Lyon Homes Warranty Service
