New Construction in San Pedro
New houses in San Pedro planned with a backyard unit if wanted: shared trenches, sized sewer and power, LADBS review and coastal checks, priced line by line.
Could a backyard unit go up at the same time as the new house? On a San Pedro lot the answer turns on yard depth, setbacks and how the utilities can be shared. State law lets a single-family lot carry an accessory unit, and the City of Los Angeles applies those rules. Building both together means a single excavation phase, shared trenches and a single site setup, so we sketch the unit with the house.
Planning the house and the unit together
The site plan places both buildings with the separation the code wants between them and the yards the city sets for each. The sewer lateral is sized for the combined fixtures, and the electrical service for both loads, whether the unit gets its own meter or shares the house's. Water lines branch at the meter. Trenches are dug and inspected once, which saves the cost of opening the yard again later. If the lot slopes, the unit can sit on its own stepped footing apart from the house foundation.
LADBS and the parcel questions
Permits for the house and the unit come from LADBS, since San Pedro lies inside the City of Los Angeles. Before design goes far, we check whether the parcel falls in the city's designated hillside area, which carries its own limits on grading and size, and whether it lies within the coastal zone, where a coastal permit may come ahead of plan check. On a coastal parcel, exposed connectors and the unit's exterior hardware are specified for salt in the air, and both buildings get the same corrosion-resistant flashing.

New Construction in San Pedro: questions
Survey work and a geotechnical report come first, and a sloping parcel may also need a geology report. With a backyard unit in the plan, the survey should show the rear and side yards accurately, since unit setbacks are measured from them. The parcel's coastal zone and hillside status are confirmed in the same early round.
A second building at the back of the lot lengthens every carry. Concrete for its footings may need a pump line run past the house, and lumber travels by hand or small loader once the main frame blocks the side yard. Pouring the unit's foundation before the house walls go up shortens that route. We price access for both buildings separately.
Yes. Send the house drawings with their structural calculations and the soils report, plus the unit's sheets if it is in the permit. If the unit is still a sketch, we price the house in full and show the unit as an option with its own lines, so you can decide on it with numbers in hand.
