New Construction in Gardena and Renting a Unit
Can a unit beside a new Gardena house be rented out? How the rules differ between a standard ADU and a JADU, and what the city may still require.
"Could the unit be rented out while we live in the main house?" That question belongs on our opening walk of a Gardena lot, because the answer differs by ADU type. No owner-occupancy rule attaches to a detached unit, an attached unit or a converted garage under current state law. A JADU inside the house does, so the choice of type shapes how the property can be used.
Rental rules by type
A standard ADU can be rented on its own, and a city cannot require the owner to live on the property. Cities may require rentals to run longer than 30 days, which rules out nightly stays. A JADU, built within the walls of the main house, keeps an owner-occupancy requirement: the owner lives in either the junior unit or the rest of the house. Selling an ADU apart from the house is generally not allowed, and the city's position on that point is checked before design.
Designing for separate living
A rentable unit needs its own entrance, a private path from the street and utilities that can be metered or split fairly. Separate electrical meters are possible but add equipment at the service. A screened yard area helps both homes. Side by side, separation is greatest with a detached unit, trenching is shortest for an attached unit, a garage conversion reuses an existing structure, and a JADU has the smallest footprint, capped at 500 square feet. The City of Gardena building department reviews whichever type is chosen.
New Construction in Gardena: common questions
Rental plans are a good reason to start early, where zoning permits a unit. Planning it alongside the house lets the entries, meters, trench and privacy screening be designed once. A unit added later has to fit around a finished yard and an existing electrical service. Rental questions get settled during design, so the chosen type matches the plan for the property.
Survey work and soil testing open the job, with a check of the water, sewer and power at the street. Design then takes in the house and the unit, and the city reviews the drawings. Any existing house comes down under its own demolition permit, and footing work waits for the building permit.
Gardena follows the statewide residential, energy and green building codes, bringing solar, sprinklers in the new house and water-saving fixtures. Gardena zoning sets height, yards and lot coverage. State ADU law overrides rules that would block a qualifying unit, including any owner-occupancy demand on a standard ADU.
