What happens in the lot check?
We confirm which agency permits your parcel, then look up its zoning and overlays: coastal zone, fire hazard mapping, Transit Priority Area status and any slope concerns. You hear back with what types of ADU could fit and what to look out for.
What happens at the site visit?
We walk the lot, measure the yard and any garage, locate the sewer, water and electrical service, and check how equipment would get in. We then send a written, itemized quote with a schedule. Nothing moves forward until you approve it.
What happens during design and permitting?
- Layout. Floor plans built around your goals, whether that is rent, family or a work space.
- Engineering. Structural design, and a soils report where the site needs one.
- Energy. Title 24 documents, with solar on a new detached unit where required.
- Finishes. Selections made before submittal so the quote stays accurate.
- Submittal. We file, track and answer every plan-check comment.
As of October 2026, state law gives the agency 15 business days to confirm completeness and 60 days to decide a complete application when a home already exists on the lot. See how long a San Diego ADU takes.
What happens during construction?
- Site preparation and utility trenching
- Foundation or slab
- Framing, roof and windows
- Plumbing, electrical and mechanical rough-in
- Insulation and drywall
- Cabinets, flooring, fixtures and paint
City inspectors sign off at set points. We schedule each inspection and update you as stages finish.
What happens at the end?
Once the final inspection passes, the unit can be occupied. We walk it with you, hand over manuals and manufacturer warranties, and close out any remaining items.
What do you need from me?
- Timely decisions on layout and finishes
- Access for the site visit, construction and inspections
- Any surveys, old plans or permit records you have
