Hollywood ADU work comes down to tight lots, older housing stock, and hillside foundations that don’t forgive sloppy planning. We’re Fielding ADU Builders, the ADU and room-addition specialist inside the Garrison Partners family, and we put the price in writing before a single board gets ordered. Whether you’re planning a backyard unit off Cahuenga or a garage conversion in the flats, call (361) 315-4177 and we’ll walk the site with you. Every job we take in Hollywood is backed by The Garrison Standard: a written one-year guarantee, permitted work done by the book, and a uniformed crew you can identify at the door.
Why Hollywood Homes Are Different
Hollywood’s housing stock runs the full span, from 1920s Spanish bungalows in Spaulding Square to mid-century stucco boxes north of Franklin and post-war tract homes along Melrose. The lot shapes create the real challenge for ADU work. Many parcels are deeper than they are wide, which pushes accessory units toward the rear property line and into setback conversations with the city. Hillside lots in Beachwood Canyon and the Oaks add foundation work and retaining wall considerations you won’t find on a flat West Hollywood pad.
Climate matters here too. Hollywood gets real heat in August and September, and any uninsulated garage or addition will make it obvious. We spec insulation, window placement, and roof overhangs for the actual summer conditions, not a generic Southern California average. The other recurring variable is access. Some Hollywood alleys are narrow enough that a standard delivery truck can’t turn in, which means materials get staged on the street and walked in. We plan for that before the first day of framing, not after the concrete truck gets stuck.
Our Main Hollywood Services
Most Hollywood homeowners call us about one of three things: adding square footage to the main house, converting an existing garage into livable space, or building a backyard ADU from the ground up. Each has its own page with pricing and process detail.
Room Addition Contractor in Hollywood
A room addition in Hollywood usually means going out the back of the house or up over an existing single-story wing. Foundation work on older Hollywood homes often means matching pier-and-beam or slab conditions that haven’t been touched since the original build, and that requires a contractor who doesn’t treat every addition like new construction on a clean lot. We handle the structural work, the roof tie-in, and the finish work as one scoped job with a written price before we start. Room Addition Contractor in Hollywood covers the full process, including what permits typically cost here.
Garage Conversion Contractor in Hollywood
Hollywood has a lot of detached garages that stopped holding cars years ago, and converting one is usually the fastest path to a rentable unit or an in-law suite. The sticking point in Hollywood is almost always electrical service and floor leveling. Old garages tend to sit low, and bringing the finished floor up to code often means re-pouring or building up the slab. We quote that work explicitly so there’s no surprise after demo starts. Garage Conversion Contractor in Hollywood walks through the timeline and the line items.
ADU Builders in Hollywood
A backyard ADU on a Hollywood lot means working within setbacks, height limits, and sometimes a hillside grading plan all at once. We build conventionally, and we also work with prefab platforms including Cover and Boxabl when the lot geometry or budget points that direction. The decision comes down to what your lot will actually permit and what your numbers look like on paper, not what one method happens to sell this year. ADU Builders in Hollywood explains how we scope a new accessory dwelling unit from survey to final inspection.

Brands We Service in Hollywood
We build with what fits the job, not what fits a sales pitch. On Hollywood projects we regularly work with Dvele and Mighty Buildings panels where the lot access supports it, and conventional framing with James Hardie siding where it doesn’t. Our brands page shows the full platform list and what each one does well.

Two things push a Hollywood quote upward: hillside foundation work and utility trenching across long, narrow lots. Both are knowable before we write the price, and the number you approve is the number on the final invoice. That’s the written-price policy, no exceptions.

FAQs About ADU Company in Hollywood
Site visits are typically scheduled within two to three business days. After that, the timeline depends on whether you’re converting an existing structure or building new. A garage conversion can move faster than a ground-up ADU because there’s less structural work, but every project starts with the same written scope and price before any work begins. Call (361) 315-4177 to set the first visit.
Some Hollywood neighborhoods fall under homeowners associations that add their own review layer on top of city permits. If your property has an HOA, we’ll ask for the architectural guidelines early and build the scope around them. The city permit is mandatory either way, and we pull every permit under our own name so the paperwork is complete and the inspection record is clean.
The Garrison Standard guarantees workmanship for 365 days in writing. If something fails inside that year, we come back and correct it at no charge. That’s not a verbal promise. It’s the same written guarantee every Fielding ADU Builders project carries, spelled out on paper before we start.
