Adding a room to a Hollywood house is not a one-size-fits-all job. A 1920s bungalow off Franklin Avenue has different bones than a 1960s hillside house above Beachwood Canyon, and the city’s zoning rules treat them differently too. We scope every addition against your specific parcel: what LADBS will approve, what the existing foundation will carry, and what the finished room will actually cost in writing before any work begins. Our crews live and work in the Hollywood area, so we’re familiar with the streets, the inspectors, and the older housing stock that dominates this part of Los Angeles. Call (361) 315-4177 for a free estimate, and we’ll give you honest numbers, not a guess.
Why Fielding ADU Builders Is Hollywood’s Preferred Room Addition Contractor Company
Fielding ADU Builders is the room addition and ADU specialist inside the Garrison Partners family. That means an independent local business that agreed to operate under The Garrison Standard: a written price before any work starts, permits pulled and inspections passed, and a full year of written guarantee on every project. Our lead on Hollywood work is Reed Calloway, who runs every job the same way: scope it properly, price it honestly, and finish it clean.
Hollywood homeowners call us because we don’t bid a room addition off a generic per-square-foot number. We pull the parcel data first: zoning, overlays, floor area limits, setback requirements. That’s the only way to give a real price instead of a lowball that changes at contract signing. The Garrison Standard covers workmanship defects for 365 days; if something fails, we come back and make it right at no charge.
Every crew member is background-checked and arrives in uniform, so you know who’s on your property. And someone picks up the phone when you call (361) 315-4177, whether it’s noon or midnight. No voicemail tag, no callback queue.
In Law Suite Builders in Hollywood
In Law Suite Builders in Hollywood are more common than many homeowners realize, because the city’s zoning and lot patterns often make an interior addition the smartest way to add living space. A true in-law suite is a self-contained living area: private entrance, sleeping space, a kitchenette or full kitchen depending on scope, and its own bathroom. In Hollywood, where many lots sit in the Hollywood Community Plan area with hillside or nonconforming zoning, the permitted size and placement of that suite depend on parcel-specific floor area and setback limits set by the Los Angeles Baseline Mansionization Ordinance. Not a generic citywide rule.
Interior Conversion Approach
Most Hollywood in-law suites are built by converting underused interior space: a large den, an enclosed porch, or a portion of the house that can be separated with a new wall and door. This keeps the project inside the existing building envelope, which often means fewer zoning triggers than a ground-up addition. The tradeoff is that the existing framing, electrical, and plumbing all need to be brought up to current code once you open the walls.
Addition With a Future Suite in Mind
We also build new additions designed to work as an in-law suite later. That means roughing in plumbing for a future kitchenette and bath, adding a private exterior door, and sizing the electrical panel for the extra load. We built a ground-floor primary suite addition for a 1920s bungalow off Whitley Avenue near the Hollywood Bowl, tying into a raised foundation and matching the original narrow clapboard siding with James Hardie lap siding. The scope, permitted through LADBS, required a structural upgrade to the existing wall line and a Hillside-area review, and the homeowners ended up with an in-law-suite-ready layout for later use.
A permitted in-law suite addition in Hollywood typically runs $180,000 to $340,000 before permit fees, depending on whether you’re converting existing space or building new square footage.
ADU Conversion in Hollywood
ADU Conversion in Hollywood usually means taking a garage, a basement, or an outbuilding and turning it into a legal accessory dwelling unit, something the city has made easier in recent years but never simple. The advantage is that the structure already exists, so you’re not paying for new foundation and framing from scratch. The complication is that most Hollywood garages built before the 1980s were never meant to be living space: the slab is too thin, the walls lack insulation, and the electrical service is minimal.
Garage Conversions
A detached garage conversion in Hollywood typically runs $120,000 to $220,000 before permit fees. That includes slab reinforcement or replacement, new framing where needed, insulation, drywall, a new electrical subpanel, plumbing for a bath and kitchenette, and all LADBS inspections. Attached garage conversions often cost less per square foot because one or two walls are already part of the conditioned house.
Prefab and Modular ADU Platforms
For some Hollywood lots, a prefab ADU from Abodu, Cover, or Dvele can cut construction time meaningfully, especially where access for a crew and materials is tight. We know these platforms and can advise whether a modular unit actually fits your lot’s setback and access constraints before you spend money on a design package. Conventional builds using James Hardie siding remain the right call when matching an older home’s exterior matters.
Trusted Brands We Service in Hollywood
We work with the prefab and modular platforms Hollywood homeowners already research online: Abodu, Cover, Dvele, and Mighty Buildings among them. We also build conventional additions with James Hardie siding, which is often the right choice for matching the lap siding profile on Hollywood’s older bungalows. Because we’re local, we keep our crews familiar with the specific detailing these systems require, which means fewer delays waiting on parts or factory support. When you call (361) 315-4177, we’ll tell you plainly whether a prefab system saves you money on your specific lot, or whether stick-built is the better path.
Common Room Addition Contractor Problems We See in Hollywood Homes
- Bidding off a generic square-foot price. We regularly see Hollywood homeowners sign a contract based on a regional per-square-foot number, then find out the parcel’s Baseline Mansionization Ordinance floor-area limits cut the addition’s size by 20 percent. The price changes, or the plans get redrawn. We pull the parcel data before we quote.
- Ignoring hillside and nonconforming zoning overlays. Much of the area above Franklin and Beachwood sits in the Hillside area, where LADBS applies stricter height, grading, and design review requirements. A planset that looks straightforward gets caught in plan check after the contract is signed. That costs time and money.
- Treating a 1920s bungalow like new construction. The raised foundations, dimensional lumber framing, and knob-and-tube remnants in Hollywood’s older homes need structural and lateral upgrades once a new room ties in. We scope for that at the start, not mid-project.
- Underestimating the permit calendar. LADBS plan check for a room addition in Hollywood, especially with Hillside review or neighborhood design review, runs longer than homeowners expect. We build a realistic schedule from day one and keep you informed through each inspection.

FAQs About Room Addition Contractor in Hollywood
The parcel’s zoning, floor area ratio limits under the Los Angeles Baseline Mansionization Ordinance, setback requirements, and any Hillside or nonconforming overlays decide how much you can add, not a generic square-foot formula. That’s why we pull the LADBS parcel data before we quote. Call (361) 315-4177 and we’ll check your specific lot at no charge.
Yes. We rough in plumbing for a future kitchenette and bath, add a private exterior door, and size the electrical panel for the extra load during the initial addition. That future-proofs the suite without paying for finishes you don’t need yet. Call (361) 315-4177 to scope it properly.
Most permitted room additions in Hollywood take 5 to 9 months from the first plan submittal through final inspection. Hillside-area review, neighborhood design review, or a nonconforming lot can add 6 to 10 weeks. We give you a written schedule before work starts, and we update it at every inspection.
On older Hollywood homes, the big variable is what’s behind the walls: foundation condition, framing rot, outdated electrical, or lateral-code upgrades required once the addition ties in. That’s why our written price includes a full scoping of the existing structure before we quote, so mid-project change orders are rare. If a change does come up, you approve it in writing before we proceed.
We work with Abodu, Cover, Dvele, and Mighty Buildings where the lot and project fit. A prefab system can cut construction time on tight Hollywood lots with limited access. We’ll tell you honestly whether modular saves you money on your parcel, or whether conventional framing is the better choice.
