Woodland Hills contractor,
building more home across Greater LA.
We're a California design-build company obsessed with one thing: unlocking square footage on the property you already own — legally, beautifully, and without the horror stories.
Born from remodels. Rebuilt for the ADU era.
HomeAdd started with home additions for neighbors in the Valley. When California opened the door to ADUs, we saw what homeowners actually needed: not a bigger house on a bigger lot, but more usable, permitted space on the property they already loved.
So we rebuilt the company around it. We coordinated architecture and permit management under one contract. We standardized detailed design-build proposals so families weren't gambling on open allowances. And we invested in project managers who work in the neighborhoods we build in — Woodland Hills, Tarzana, Encino, Sherman Oaks, and out through the Conejo Valley.
Today we're a California design-build company delivering detached ADUs, attached ADUs, above-garage units, JADUs, garage conversions, and full home additions across Greater Los Angeles, from Ventura to Long Beach — with a 5.0 rating from 27 reviews on our Google Business Profile that we've earned by treating every project like it's next door.
Four things we refuse to compromise on.
Architecture, engineering, permits, and construction under one roof. One team accountable from first sketch to final walkthrough — no finger-pointing between designer and builder.
We coordinate permits with LADBS, LA County, Ventura County and the city building departments across Los Angeles and Ventura counties, and we review local ADU ordinances, setbacks, fire zones, and coastal overlays before we quote you.
A detailed line-item proposal after design, with itemized allowances. Any change to scope or price goes through a written change order you approve first.
Every project gets a named project manager as your point of contact, with regular progress updates through construction.
How our practice took shape.
- RootsRooted in the Valley
Started with room additions and remodels across Woodland Hills, Tarzana, and Encino for neighbors and referrals.
- FocusAll-in on ADUs
California's ADU reforms opened the door. We built our practice around detached, attached, and garage-conversion ADUs for infill lots.
- IntegrateDesign-build under one roof
Coordinated architecture, permitting, and construction so clients get one contract, one timeline, one accountable team.
- TodayGreater Los Angeles
Serving Los Angeles and southern Ventura County from our Woodland Hills HQ, with a coordinated team of PMs, designers, and trade partners.
Every kind of ADU. Every kind of addition.
We only build one category of thing — additive residential square footage — and we build every version of it. That focus means our projects are scoped clearly and planned around local permit rules.

HomeAdd built a detached ADU on our property and did an excellent job. From the beginning the team took the time to understand what we needed and helped us navigate the design and permitting process. They stayed on budget, communication was top-notch, and the final ADU is a perfect addition to our home.
