About ADU Builds

Build More Living Space on Your Land

ADU construction gives you a fully managed way to add a backyard cottage or detached living unit on land you already own. It fits homeowners, second-home owners, and investors who want more usable space without guessing through the build.

  • One Clear Contractor
    You get one team to manage planning, site work, building, and finish-out. That means less confusion, better oversight, and a faster path to a completed ADU.
  • More Use From Land
    An accessory dwelling unit helps you add space for family, guests, or flexible living. It lets you get more from the property you already have.
  • Built for Serious Projects
    This is a good fit if you are ready to move forward on a real build. Lighthouse Contracting handles substantial residential work, not small patch jobs.
  • Reliable Site Management
    If you are not local full time, clear updates matter. You get dependable communication and on-site management from a team used to build-on-your-land projects.
