ADU Build Schedule: What to Expect

We do not promise a fixed number of weeks. Permits, utilities, weather, and the lot decide the schedule. Ask for a timeline on your site.

No fixed week count

We do not promise that an ADU will finish in a set number of weeks. A ready site with utilities at the line and permits in hand moves differently than a lot that still needs septic design, ledge work, or a town review.

What usually changes the schedule

  • Permits. Work cannot start while an application is sitting with the town.
  • Weather. A bad stretch can pause excavation.
  • Design changes after permits are issued.
  • Long utility runs when water, power, or septic are not already at the property line.

Ask for a schedule on your lot. Compare the 10 ADU models ($147,000–$388,000), start with instant pricing, or book a build consult.
