How an ADU gets built in Long Beach

How an ADU gets built in Long Beach

  1. Check feasibility

    Look at your lot, your goals and your budget. Confirm the basic rules for your property with the city before you spend money on design.

  2. Design and plans

    Work with a designer or your builder to draw floor plans, site plans and utility details that the city can review.

  3. Plan check and permit

    Submit your plans to the City of Long Beach. The city checks them and issues the building permit when they meet the rules. Review times vary.

  4. Construction and inspections

    Build the unit under the approved permit. The city inspects key stages, such as foundation, framing, electrical and plumbing.

  5. Final sign-off and move-in

    After the final inspection passes, the city signs off the project. You can then move in or start renting the unit, if the rules allow it.
