Room Addition
Contractor in Encino, CA

The typical Encino house is a 2,500–4,000 sq ft ranch or traditional on a 17,500 sq ft or larger lot, and the room that is missing is usually a primary suite, a second living space or a home office. A well-built addition gives you the extra bedroom, the primary suite, the bigger kitchen, or the second story you need, and it does it on the street and in the school district you already chose.

Right Image Builders is a licensed general contractor based in Valley Glen, a short drive east of Encino. An addition is a serious structural project — new foundation, framing tied into the existing house, roof and systems extended, all engineered and permitted. We manage the whole thing: architectural plans, structural engineering, LADBS permits, and construction, under one written fixed-price contract and one accountable company.

Encino's big RA- and RE-zoned lots shape what's possible: generous room for large ground-floor additions and primary suites, and solid homes that take a second story well. Where the land climbs into the Encino Hills, the same project can call for hillside grading and foundation engineering. The art is in making the new square footage look original — matched rooflines, stucco, and windows — not bolted on.

Every Encino addition starts with the parcel. Many homes here sit on large RA- or RE-zoned lots — among the biggest in the Valley — which set the rules: how much floor area you can add, and the front, side, and rear setbacks you have to keep clear. A ground-floor addition trades yard for square footage; a second story adds space without shrinking the lot — the right choice depends on your goals and your lot, and Encino lots vary, from the flats of Amestoy Estates and Royal Oaks to the slopes of the Encino Hills.

Because Encino is City of Los Angeles, additions are permitted through LADBS — an authority we work with regularly from our Valley Glen shop a short drive east. That local familiarity matters on additions, where plan check and structural review are more involved than a simple remodel, and more so still on Encino Hills lots that bring hillside grading into the picture.

The first thing we do at the free consultation is pull your parcel on ZIMAS: zone, lot area, the floor-area limit, setbacks and any hillside or fire-zone overlay, so you know the buildable square footage before you spend anything on drawings. Most of Encino is RA (17,500 sq ft minimum lots) and RE across much of Encino, RE40 and hillside parcels in the hills.

Encino covers two very different building conditions. North of Ventura, in Amestoy Estates and the surrounding flats (ZIP 91316), many properties are larger, level lots — some RA- or RE-zoned — where a wide rear addition or a primary suite can often be placed without touching the front setback; parcel-specific zoning still has to be checked before any square footage is promised. South of Ventura, in Royal Oaks and the Encino Hills (ZIP 91436), estate parcels climb toward Mulholland; many are designated Hillside Area under the Baseline Hillside Ordinance and some fall in a Very High Fire Hazard Severity Zone, which brings grading limits, engineered foundations, drainage design and fire-rated exterior assemblies into the project. We pull the zoning and hazard designations for your exact parcel at the free consultation and design to them.

An Encino room addition usually needs a few months for design, structural engineering and LADBS plan check before construction, then roughly three to five months of building for a ground-floor or rear addition and longer for a primary-suite wing or a second story. Hillside estates south of Ventura should budget extra time for grading and geotechnical review.

On the flats. A rear addition on an Amestoy Estates-type lot is the straightforward case: architectural plans, structural calculations, LADBS plan check, then foundation, framing, roof tie-in, rough trades, inspections and finishes. Larger suites with new bathrooms add plumbing and HVAC scope but rarely change the sequence.

In the hills. Royal Oaks and Encino Hills parcels can require a soils report, engineered retaining or caisson foundations, a grading plan and hillside review before plan check clears. That front-loads the schedule; construction itself is often similar once the foundation is in. The fixed-price proposal shows both phases with realistic dates.

Start at cslb.ca.gov: check the license number (ours is 1021284), confirm it is active with a bond and workers' compensation on file, and ask for liability and workers' comp certificates in writing. Encino additions are often large — a primary suite or a full rear wing — so make sure the contractor, not you, is responsible for the architect, the structural engineer and the LADBS submittal, including any hillside, grading or fire-zone items on estate parcels.

Get a written fixed-price contract with an itemized scope, clearly stated allowances for finishes, written change orders, and progress payments tied to completed work. California limits the down payment to $1,000 or 10 percent of the contract, whichever is less. Ask how the addition will be tied into the existing house — foundation, framing, roof and stucco — and how a large lot's existing landscaping, pool equipment or utility runs will be protected during construction.
