Designing, permitting, and building detached ADUs, garage conversions, and Junior ADUs for Encino and Encino Hills homeowners. Office on Ventura Blvd. CSLB License #972213.
Hillstar Construction is a licensed Encino ADU contractor. Our office sits on Ventura Boulevard a short drive from central Encino — which means a real person is on your property for the first site visit, not a sales representative passing through from across the county. We work with homeowners across Encino, Encino Hills, Tarzana, and Sherman Oaks on detached ADUs, garage-conversion ADUs, above-garage units, and Junior ADUs (JADUs) — each one shaped around the zoning, lot size, hillside status, and architectural context of the specific property.
Every project starts with a free on-site consultation, a clear written scope, and a straight answer about what your lot can actually support.

Encino spans a wider range of lot conditions than most LA neighborhoods. South of Ventura Boulevard you'll find flat parcels in the Lake Encino and Encino Commons areas, often zoned R1 or RE with 5,000 to 20,000 square-foot lots. North of Ventura, Encino Hills climbs into slope-designated terrain where the Baseline Hillside Ordinance adds extra design and grading standards on top of the ADU rules. Portions of the neighborhood sit within private HOA communities — including parts of Encino Hills and the Royal Oaks area — where an architectural review committee may weigh in before the city does.
A contractor who builds the same ADU regardless of lot condition tends to fight plan check, fight neighbors, or fight both. We design for your lot's actual zoning, slope, access, and HOA context first — because that's what makes the project go through the city cleanly and sit well with the neighborhood.
For homeowners still deciding between an ADU and a main-home expansion, our home addition option is sometimes the better fit when the lot's buildable envelope doesn't support a meaningful detached structure.
ADUs in Encino are governed by California state law and Los Angeles city rules — the same framework that applies across the City of LA. The baseline rules below are what virtually every Encino property starts with. The specific envelope you get depends on zoning, hillside status, and any HOA or architectural overlay that applies to your community.
Encino contains a mix of R1 (5,000 sq ft minimum lot), RA (17,500 sq ft, originally agricultural), and RE variants — RE9, RE11, RE15, RE20, and RE40 — with minimum lot sizes from 9,000 up to 40,000 square feet. Most Encino homes south of the 101 sit on R1 or RE lots; Encino Hills has more RE and RA parcels. Larger lot size usually translates to more buildable ADU envelope.
State law requires Los Angeles to allow a detached ADU of at least 850 square feet for a studio or one-bedroom, or at least 1,000 square feet for two or more bedrooms. LA permits detached ADUs up to 1,200 square feet. On most Encino RE lots, the full 1,200 square feet is comfortably achievable with room for landscaping and privacy buffers.
State law limits required side and rear setbacks to no more than four feet for a new detached or attached ADU. No setback is required where you convert an existing garage in its existing footprint.
No new or replacement parking is required for an ADU on any lot within a half-mile walking distance of public transit. Much of the Ventura Boulevard corridor through Encino meets that threshold. Where parking is required, it's limited to one space per unit or bedroom, and tandem parking on an existing driveway counts.
State law requires the city to determine whether your ADU application is complete within 15 business days and to approve or deny a complete application within 60 days. LADBS processes Encino ADU applications through the same Valley branch that handles Woodland Hills and Sherman Oaks projects. Hillside or HOA-review projects take longer.
Encino Hills lies within the LA Baseline Hillside Ordinance area. Hillside-designated lots are subject to additional height, grading, and design standards. Slope also drives foundation engineering cost. The Los Angeles permit guide walks through the broader permit flow in more detail.
Encino's lot-size and zoning variety means no single ADU configuration fits every property. Here's how we actually match ADU type to lot conditions in the neighborhood:
By far the most common Encino configuration, and usually the right call on RE-zoned parcels with flat rear-yard buildable area. A freestanding 800 to 1,200 square-foot ADU offers the most design flexibility, the highest long-term value, and the cleanest separation between main home and secondary unit — which matters in Encino where ADUs are often built for family members, adult children returning home, or as a dedicated work-from-home structure rather than strictly for rental income.
Useful on tighter R1 lots where rear-yard ground area is already spoken for by pool, landscaping, or setback constraints. Los Angeles allows ADUs above a garage with setbacks of no more than five feet from side and rear lot lines. Common solution in the older tract-style streets in southern Encino.
Works well on older Encino properties with detached garages that aren't serving much day-to-day purpose. State law allows garage-to-ADU conversions with no required setback from the existing footprint, which makes them among the fastest ADU types to permit. We check for structural issues, foundation condition, and drainage before committing to a conversion path.
Encino Hills lots often support a detached ADU, but the engineering side matters more than on flat parcels. Caissons or spread footings sized to slope, adequate access for concrete trucks and crane placement, drainage to protect both the main home and the new structure — these are the details that separate hillside ADUs that actually get built from hillside ADUs that stall in plan check.
A JADU is carved out of the existing primary home — up to 500 square feet — and fits best when a detached ADU isn't realistic or the homeowner only needs a small additional unit. JADUs continue to have owner-occupancy requirements under state law. Often paired with a broader home remodeling project when the main house is already being reworked.
A realistic Encino ADU timeline from first site visit to certificate of occupancy is roughly 6 to 12 months. Permits move on the state-mandated 15-day / 60-day schedule when plans are submitted correct; hillside lots, HOA review, and lots requiring utility upgrades add time. Construction itself runs 3 to 6 months for most detached builds once ground is broken.
Encino's buyer profile skews toward higher finish levels than the average LA ADU — hardwood floors, stone counters, higher-spec cabinetry, and architectural details that tie into existing mid-century or transitional main homes. That raises cost per square foot compared to a base-spec build. Our cost and ROI guide for building an ADU in Los Angeles breaks down the numbers and the variables that move them the most.
What we commit to on every Encino project: a written scope, a clear price, no surprise change orders unless construction uncovers something that genuinely requires one, and direct access to your project manager from kickoff through the final walkthrough. The full ADU construction process is covered step-by-step in our construction guide.

Lior was such a pleasure to work with for our guest house remodel. He was so easy to get in touch with, incredibly responsive and finished the job early.
— Amy Christine, February 2019Lior is very personable and has many decades of construction experience. We appreciated his sincere evaluation of our project.
— Ann Anterasian, April 2019Encino has a higher share of larger single-family parcels than most Valley neighborhoods — particularly in RE (Residential Estate) zones, where minimum lot sizes range from 9,000 to 40,000 square feet. On lots that size, placing a 1,000 to 1,200 square-foot detached ADU with proper setbacks, separate utility connections, and its own yard is straightforward. On standard R1 lots (5,000 sq ft minimum), a detached ADU is still achievable but the buildable envelope is tighter. We walk through your specific lot's buildable area at the first site visit.
Yes, in most cases. Encino Hills lies within the LA Baseline Hillside Ordinance area, which applies additional height, grading, and design standards on top of standard ADU rules. Slope, access, and foundation design add time and cost compared to a flat Valley-floor lot, but hillside ADUs are routinely permitted when designed correctly. We evaluate slope, soil conditions, access for construction vehicles, and any required geotechnical or drainage work before quoting.
A well-built ADU typically adds meaningful appraised value to an Encino property and creates the option of rental income, multigenerational housing, or a dedicated work-from-home space. The actual dollar impact depends on size, finish level, and whether the ADU has its own access and utilities. We can't promise a specific resale number — that depends on the market when you sell — but we do design every ADU to look and function like a real second residence, not an afterthought, which is what supports value.
Encino has a strong mid-century modern inventory — single-story homes with low-slung roofs, clerestory windows, post-and-beam framing, and warm wood and stone accents. A good detached ADU for that context echoes those elements: matching roof pitch and overhangs, complementary siding material (board-and-batten wood, smooth stucco, or a mix), and window proportions that read as part of the same property. Our design process starts by photographing the main home and bringing those details into the ADU exterior so the finished result looks intentional, not grafted on.
Los Angeles regulates short-term rentals under the Home-Sharing Ordinance, which generally restricts short-term rental (under 30 days) to the host's primary residence and prohibits using an ADU built under state ADU law as a short-term rental. Long-term rentals of 30 days or more are allowed. If rental income is a major driver of your project, plan around long-term tenants rather than short-term platforms. We confirm the current rule at the consultation since the ordinance has been amended multiple times.
State law prevents HOAs from outright banning ADUs but does allow reasonable architectural and aesthetic standards. Some gated Encino communities and neighborhoods with active HOAs (for example portions of Encino Hills and the Royal Oaks area) have active architectural review committees that can require specific siding materials, roof styles, colors, or landscape buffers. We handle the HOA submission process alongside the city permit process when one applies — you sign off on the design once, and we coordinate both tracks from there.
