“Pre-approved ADU plans are underused. LADBS has a library of pre-approved designs — plan check drops from 12 weeks to 4 weeks. You don't pay for custom architectural work. The tradeoff is you work within the footprint and height limits of the approved design. For 90% of standard lots, this is the right path.”
Request a soils report early for detached ADUs on sloped lots. The soils report determines your foundation type. A project designed around a slab foundation that requires piers upon soils testing is a significant budget change. Know the foundation requirements before design is finalized.
