ADU Builder & Contractor
in Tarzana, CA

Few Valley neighborhoods are as ADU-friendly as Tarzana, and the reason is the land. The flats north of Ventura Boulevard sit on big, level lots — exactly the kind of parcel where a full-size detached ADU up to 1,200 sq ft is genuinely feasible, with room left over for the yard. It's a different starting point from the tight lots elsewhere in the Valley.

South of Ventura, the streets climb into the Tarzana hills. Those lots are larger and more valuable, and they make excellent ADU sites too — but they're governed by the City of LA Hillside Ordinance, which brings grading, retaining, drainage, and access into the design. Both sides of the boulevard are strong ADU opportunities; they just call for different expertise.

In Tarzana an ADU is permitted through LADBS (City of Los Angeles) at the Van Nuys Development Services Center, 6262 Van Nuys Blvd, and power and water connections go through LADWP; the typical site is a big level lot north of Ventura with room for a full-size detached unit, or an RA Melody Acres parcel where horse-keeping setbacks apply, which is what decides between a garage conversion, a JADU and a detached unit. One contract covers design, LADBS, City of Los Angeles, with Baseline Hillside Ordinance review south of Ventura Boulevard and construction; the project lead who does your estimate at home runs the build, and the itemized fixed-price proposal follows within 3–5 business days.

Based in Valley Glen, a straight drive east, we'll tell you at the free feasibility visit exactly what your Tarzana lot supports — a full detached unit on the flats, a hillside build to the south, or a cost-effective garage conversion — before you spend a dollar on plans.

In Tarzana, ADU strategy comes down to which side of Ventura Boulevard you're on. North — the flats and the Vanalden area — the lots are big and level, which makes a full-size detached ADU very feasible and a strong candidate for LADBS Standard Plans. There's genuine room here for a comfortable 1,000–1,200 sq ft unit without crowding the yard.

South of Ventura, in the Tarzana hills, the lots are larger, more valuable, and have an upscale, semi-rural feel — but they're governed by the City of LA Hillside Ordinance. Grading limits, retaining, drainage, haul routes, and access all have to be engineered and permitted correctly. Done right, a hillside ADU is a premium asset; done without that expertise, it's a stalled project. We design and permit for the slope from day one.

Everything is City of Los Angeles and permitted through LADBS. From our Valley Glen shop, a straight drive east on the Valley floor, we stay hands-on through grading, framing, and final inspection — whether your Tarzana lot is on the flats or up in the hills.
