Common questions
Can I build an ADU on my lot?
Many Los Angeles County properties qualify, but setbacks, utilities, and city rules vary. We review your property before giving an estimate.
Who prepares the plans?
Plans are prepared by licensed design professionals and engineers we coordinate with. Design and engineering fees are listed separately in your estimate.
How long does an ADU take?
Timelines depend mainly on city plan check, corrections, and inspections. We give you an expected timeline in writing and update you as the city responds.
