Adding an ADU or home addition in Hollywood comes down to three realities: lots are tighter than they look on paper, the housing stock spans nearly a century of building codes, and the hills change everything about foundation and drainage work. We’re Sutton ADU Builders, and we help Hollywood homeowners plan additions that actually fit their property, their budget, and the city’s permitting process. Whether you’re weighing a detached unit behind a 1920s bungalow or a second-story addition in the flats, we give you a written price before any work begins. Call (472) 248-8213 to talk through your lot.
Why Hollywood Homes Are Different
Hollywood’s housing stock is a patchwork. You’ll find 1920s Spanish-style bungalows in Spaulding Square, mid-century apartments near Hollywood and Western, and hillside homes off Laurel Canyon and Beachwood Drive that were built into slopes steep enough to make a structural engineer’s first visit feel like a site survey. That age range matters. Older Hollywood homes often have foundations that were never designed for a second structure’s setbacks, and many sit on lots that predate current code requirements for ADUs in California. A detached unit that looks simple on a flat lot can become a retaining-wall project on a hillside. Soil conditions also shift neighborhood to neighborhood. Homes in the flats near Melrose often sit on older, compacted fill, while hillside parcels in the Oaks or above Franklin Avenue regularly need additional drainage planning. Add in Hollywood’s specific zoning overlays, and you get a city where a standard plan set almost never drops straight onto a lot without revisions. That’s why we walk every property before we quote. No satellite-image estimates, no assumptions about your foundation.
Our Main Hollywood Services
Most Hollywood homeowners we talk to are choosing between expanding their existing footprint or building a separate structure in the back. Here’s what each path looks like in this city.
Home Addition Contractor in Hollywood
A home addition in Hollywood usually means extending outward or upward on a lot that’s already close to its coverage limit. Older homes here often have nonconforming setbacks (the required gap between your structure and the property line), which means the design phase takes longer and the permit review is more particular. We handle the full scope: foundation, framing, roofing, stucco or siding matched to your existing exterior, interior finish work, and pulling permits with the city. If your addition touches a hillside, we bring in a soils engineer before we ever submit plans. Home Addition Contractor in Hollywood
ADU Builders in Hollywood
Detached ADUs are the fastest way to add rentable or family space on a Hollywood lot that still has rear yard to spare. California’s statewide ADU rules have loosened a lot of old restrictions, but Hollywood still has its own height limits, parking rules near transit corridors, and historic-district reviews in some pockets. We build stick-framed units and also work regularly with prefab brands like Cover and Dvele, which can shorten on-site construction time considerably on a tight Hollywood lot.

Room Addition Contractor in Hollywood
A single room addition – a home office, a primary suite, a family room – often fits into Hollywood homes that can’t accommodate a full second-story addition. These projects tend to move faster through permitting because they trigger fewer code reviews, but the same Hollywood-specific issues apply: foundation tie-ins on older slabs, roofline matching on bungalows, and neighbor notification if you’re building close to a shared property line. We give you a fixed written price and a timeline before demo starts. Room Addition Contractor in Hollywood

What pushes a Hollywood ADU or addition toward the top of these ranges is usually site work: hillside retaining, foundation upgrades on older homes, or utility trenching across a long, narrow lot. Seldom is it the finishes. The Threshold Standard means the price you see is the price we build to. We put it in writing before we start, and if any element of our workmanship fails within a full year, we return and fix it at no cost.

FAQs About ADU Company in Hollywood
Most detached ADUs in Hollywood run six to nine months from design to final inspection, with garage conversions typically landing closer to four to six months. Hillside lots and historic-district reviews can add time. We’ll give you a project schedule in writing before you sign anything.
If your Hollywood home is in an HOA-governed development, yes – but California law limits how much an HOA can restrict ADUs. We help you sort through the HOA’s architectural review process alongside the city’s permit requirements so both tracks move in parallel.
