What we build

Backyard ADU in Rancho Park, yard side
Backyard ADU in Rancho Park: two primary suites, each with its own bath and walk-in closet. See the project.

How a job runs

  1. The free site visit comes first. On an ADU lot we check the setbacks, easements, the sewer line and panel capacity.
  2. You get a written scope and quote for that address.
  3. The payment schedule is agreed with you before the contract is signed.
  4. We draw the plans, file with the city, answer the plan-check corrections and meet the inspectors.
  5. A lien release comes with each payment.
