New Construction and ADUs in San Pedro
When a San Pedro house is torn down and rebuilt, new construction leads and the ADU is drawn into the same plan set, sized for utilities and checked by LADBS.
Tearing down a San Pedro house to build a new one puts new construction first on the list. The ADU is drawn into the same plan set as the new home, so its placement, utilities and driveway are decided together. A detached unit, an attached one or a JADU can all be designed in from the start, and a garage conversion only enters the picture once there is a garage to convert.
A design for both dwellings
With both dwellings on a shared drawing set, the sewer lateral, water service and electrical service are sized a single time for the combined load. An attached unit gets a fire rated separation wall framed in with the rest of the house, and a JADU can be roughed in with its own outside entry. A detached unit can be poured during the same foundation phase. For a lot near the water, the exterior specification calls for stainless connectors, a continuous membrane behind the siding and window hardware that resists corrosion in damp, mineral laden air.
Review at LADBS
Plans for a San Pedro rebuild and its ADU go to LADBS, which handles building permits for every City of Los Angeles community and checks the set against state ADU law and city zoning. If the parcel lies close enough to the water, a separate development permit may be needed before construction is permitted, so the address is looked up at the start. Inspections follow the foundation, framing, rough trades and insulation before the final. Lomita and Rolling Hills Estates are separate cities with reviewers of their own, and the combined plan approach works there too.
