Fielding ADU Builders handles ADU construction, garage conversions, and room additions across Long Beach, CA. The city’s housing stock runs older than most of Los Angeles County, which means lot shapes, setback rules, and existing foundations tend to drive more of the budget than square footage alone. We put the price in writing before any work begins, and every project carries a one-year written guarantee. Call (361) 315-4177 for a free estimate.
Why Long Beach Homes Are Different
Long Beach is a city of tight lots and older framing. Homes built between the 1920s and 1950s dominate neighborhoods like Belmont Heights, Bluff Park, and Rose Park, with many still resting on raised foundations that were never laid out for a second unit. That matters when we plan an ADU or conversion: sewer lateral positions, panel capacity, and the condition of the original sill plate all have to be verified before we commit to a price. The marine layer means exterior materials need to handle year-round moisture, so we lean on James Hardie siding and similar products that hold up in coastal air. Some Long Beach lots fall inside historic districts, where the city requires design review before permits can be pulled. A setback variance (the city’s written permission to build closer to the property line than the standard rule allows) is more common here than in newer developments, and it adds weeks to the timeline. We price that reality up front rather than surprising you with it at the door.
Our Main Long Beach Services
Most Long Beach homeowners come to us for one of three jobs: adding a permitted room, converting a garage into living space, or building a backyard ADU. Each project has its own Long Beach page with pricing and local specifics.
Room Addition Contractor in Long Beach
A room addition in Long Beach usually means building over an existing single-story footprint or extending outward on a lot that has room to give. We handle the structural work, the city permits, and the finish carpentry. Long Beach requires engineered drawings for most additions over 120 square feet, and we bring in the structural engineer ourselves. The full breakdown of what a permitted room addition costs is on the Room Addition Contractor in Long Beach page.
Garage Conversion Contractor in Long Beach
Garage conversions are the fastest route to extra living space when the existing structure is sound. In Long Beach, many detached garages were built as accessory structures on older permits, which means we often have to bring electrical and insulation up to current code before the conversion can pass inspection. The number you approve on day one is the number on the final invoice. Details and pricing are on the Garage Conversion Contractor in Long Beach page.
ADU Builders in Long Beach
Long Beach ADUs fall into two camps: a detached unit in the backyard, or an attached unit carved out of the existing home’s footprint. We work with prefab platforms including Abodu, Cover, and Dvele, plus conventional framing. Lot coverage rules, utility trenching, and foundation type all shape the final number. The full method-by-method breakdown is on the ADU Builders in Long Beach page.
