An ADU in Long Beach usually costs between $180,000 and $420,000 depending on whether you convert a garage, build over it, or pour a completely new foundation. The typical project takes four to seven months from the first plan to final inspection. Most of that time is spent on design, permits, and the utility work that older neighborhoods here require. Call (562) 362-3885 and we’ll put a written price in front of you before anything gets signed.
Why Long Beach Homes Are Different

Long Beach’s dense single-family neighborhoods were mostly built before 1940. You’ll see 1920s bungalows in Rose Park, Spanish Revival stuccos throughout Bluff Heights, and a solid run of 1950s and 60s ranch homes in the eastside tracts around Los Altos and El Dorado Park. Those houses sit on lots that are often only 25 to 40 feet wide, with detached garages pushed to the rear alley. That shape changes the ADU conversation immediately.
Long, narrow lots mean side-yard setbacks get tight fast. A lot of the ADUs we plan in Long Beach end up as garage conversions or two-story units over a new garage, because that layout preserves the driveway and stays clear of the side property lines. In historic districts like Bluff Park or Carroll Park, the city’s design review layer can limit what’s visible from the street, which pushes more projects toward alley-facing units or conversions that keep the original facade untouched.
The housing stock also affects foundations and utilities. Older homes here sit on a mix of raised wood floors and slab, and tying a new ADU’s sewer line to the main often means trenching through a long, narrow yard. We plan for that from the first site visit, not after the hole is open.
Our Main Long Beach Services
Most homeowners in Long Beach start with one of three jobs. Each has its own dedicated page with pricing, timelines, and what to expect in Long Beach specifically.
ADU Builders in Long Beach
A detached ADU in a Long Beach backyard is usually a 400 to 800 square foot unit with its own kitchen, bath, and entrance. The city’s older neighborhoods and historic districts favor compact, alley-facing designs, and many homeowners choose prefab systems from brands like Abodu or Plant Prefab to reduce on-site construction time. We handle the foundation, utility connections, and all permits, with the written price locked before work begins. See the full breakdown on our ADU Builders in Long Beach page.

Home Addition Contractor in Long Beach
A home addition in Long Beach means adding square footage to the main house itself, and that gets complicated on lots under 40 feet wide. Most additions here push out the back rather than the side, which often means reworking the existing roofline and foundation connection. The age of the home matters: a 1920s bungalow has different framing than a 1960s ranch, and we plan the structural work accordingly. See Home Addition Contractor in Long Beach for details and pricing.

Room Addition Contractor in Long Beach
A room addition is a single space added to the house, like a primary bedroom, a family room, or a home office. On Long Beach’s narrow lots, this often becomes a rear bump-out that keeps the existing footprint’s street view intact. Coastal air and the marine layer mean we pay close attention to moisture barriers and ventilation on every exterior wall we open. Full scope and numbers are on the Room Addition Contractor in Long Beach page.

FAQs About ADU Company in Long Beach

A site visit usually happens within one to three business days of your call.

Call (562) 362-3885 and we’ll give you a written project schedule.
