Trusted ADU Builder LA
Los Angeles homeowners are turning to ADUs for everything from rental income to multigenerational living. At Home Services Plus, we design and build fully permitted, move-in-ready ADUs across the city – from modern casitas in the Valley to garage conversions in Culver City and hillside builds in Silver Lake.
We handle everything: zoning reviews, engineering, permits, construction, and finishing touches. You get a stylish, functional space without the headaches.
Detached ADUs (Backyard Homes)
Backyard ADUs are popular across LA because they provide privacy and independence. We’ve built detached units ranging from compact studios to spacious 1,200 sq ft guest houses, complete with full kitchens, baths, and separate utilities. Whether it’s for extended family, an Airbnb rental, or boosting property value, a detached ADU adds flexibility and long-term return.
Prefab ADUs in Los Angeles
If speed and cost control are priorities, a prefab ADU might be your best option. Our prefabricated models start at $189,000 and include curated finishes with options for upgrades. We manage all site prep, foundations, and utility tie-ins, so your unit is delivered and completed on a much faster timeline than a fully custom build.
LA Garage Conversions (JADUs)
In neighborhoods where space is tight, garage conversions are a smart way to add livable square footage. We turn unused garages into legal junior ADUs with kitchenettes, full insulation, and modern finishes. Many homeowners use them for rental income, home offices, or private guest suites, especially in high-demand areas like Venice and West LA.
ADA-Compliant & Aging-in-Place ADUs
Los Angeles families often need ADUs that double as safe, long-term living spaces for aging parents or relatives with mobility needs. We design ADA-compliant units with roll-in showers, ramps, comfort-height fixtures, and wider doorways – all integrated into modern, stylish layouts.

Frequently Asked Questions
Yes, when done with proper permits. We’ve built many JADUs across LA and ensure every project meets LADBS and state requirements.
