Sherman Oaks Home Addition Contractor

The Right Image Approach

More Room,
Without Moving

Outgrowing your Sherman Oaks home doesn't have to mean buying a bigger one — in a market this expensive, staying and adding on is often the smarter move. 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 neighborhood you already chose.

Right Image Builders is a licensed general contractor based in Valley Glen, just over the hill from Sherman Oaks. 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.

Sherman Oaks homes range from 1940s–60s ranch and mid-century to Spanish, on flat lots north of Ventura and larger hillside lots to the south. That shapes what's possible: where lots are tight, a second story adds space without touching the yard; in the hills, the city's Hillside Ordinance guides how — and how much — you build. The art is making the new square footage look original, not bolted on.

What We Build

Ways to Add
Space in Sherman Oaks

Room Additions

A new bedroom, family room, home office, or expanded living space extended off the existing house — new foundation, framing, roof, and systems, tied cleanly into your Sherman Oaks home and permitted through LADBS.

Primary Suite Additions

Add the primary bedroom, walk-in closet, and en-suite bath these 1940s–60s homes were never built with — a high-return addition that transforms how the house lives, and a favorite in a design-conscious Sherman Oaks market.

Second-Story Additions

When the lot is tight or you want to keep the yard, we build up. Second-story additions require careful structural engineering to carry the new load on the existing foundation — exactly the work a licensed contractor engineers and permits.

Bump-Outs & Kitchen Expansions

Sometimes a few hundred square feet changes everything — pushing out a cramped kitchen or dining area, or adding a mudroom or breakfast nook. Smaller additions that deliver outsized daily impact.

Engineering & Permits

Every addition is designed, structurally engineered, and permitted through LADBS — including Hillside Ordinance review for homes in the hills south of Ventura. We coordinate the plans, manage plan check, and carry the project to signed-off final inspection.

Seamless Integration

Matched rooflines, stucco texture, window styles, and floor heights so the addition reads as part of the original home. The difference between an addition that adds value and one that looks tacked on.

Building in Sherman Oaks

What Your Sherman Oaks
Lot Will Allow

Every Sherman Oaks addition starts with the parcel. Most homes here sit on R1 single-family lots, which set the rules: how much floor area you can add, and the front, side, and rear setbacks you have to keep clear. North of Ventura the lots are typically flat; to the south they climb into the hills, where lots run larger but come with more constraints. A ground-floor addition trades yard for square footage; a second story adds space without shrinking the lot.

Because Sherman Oaks is City of Los Angeles, additions are permitted and inspected through LADBS. Homes in the hills south of Ventura Boulevard fall under the city's Hillside Ordinance, which can add grading, haul-route, and access requirements to the plan-check process. That local knowledge matters on additions, where structural review is already more involved than a simple remodel — and where an out-of-area bidder gets surprised.

The first thing we do at the free consultation is pull your zoning and tell you honestly what's buildable — square footage, height, and setbacks, plus any hillside rules that apply — before you spend a dollar on design. [VERIFY exact FAR/setback figures with owner/current LADBS zoning.]

What It Costs

Sherman Oaks Home Addition
Cost Ranges

Addition Type	Typical Range	What's Involved
Bump-Out	$70K–$140K	A few hundred square feet — kitchen or dining expansion, mudroom — with new foundation, framing, and matched exterior.
Room / Suite Addition	$140K–$280K	A full room or primary suite — foundation, framing, roof, systems, finishes, engineered and permitted.
Second Story	$280K–$500K+	Adding a full upper level — significant structural engineering to carry the load, plus stairs, systems, and full finishes; hillside lots add cost.

Additions vary widely with size, finishes, hillside conditions, and structural scope. Ranges are for planning only; your fixed-price proposal follows the free consultation and zoning review. [VERIFY — owner to confirm current cost ranges before publish.]

Sherman Oaks Home Addition FAQ

Questions We
Hear in Sherman Oaks

How much can I add onto my home in Sherman Oaks?+

It depends on your lot size, zoning, and setbacks. Most Sherman Oaks homes are on R1 single-family lots, where you can typically expand up to a floor-area ratio the city allows while keeping required front, side, and rear setbacks. Lots south of Ventura Boulevard are often larger but sit in the hills, where the city's Hillside Ordinance adds grading and access rules. A ground-floor addition uses yard space; a second-story addition adds square footage without shrinking the yard. We pull your parcel's zoning at the free consultation and tell you exactly how much you can build. [VERIFY exact FAR/setback limits with owner/current LADBS zoning.]

Do you handle the permits and engineering for a home addition in Sherman Oaks?+

Yes — a home addition is a permitted, engineered project from start to finish, and we manage all of it. Sherman Oaks is City of Los Angeles, so the addition is permitted and inspected through LADBS. We coordinate the architectural plans and structural engineering, submit for plan check, and carry the project to signed-off final inspection — including the extra Hillside Ordinance review that applies to homes in the hills south of Ventura Boulevard. You never deal with the counter.

What's the difference between a home addition and an ADU?+

A home addition expands your existing house — a new bedroom, a primary suite, a larger kitchen, or a second story — as part of the same home, sharing its systems and entrance. An ADU is a separate, independent dwelling unit with its own kitchen, bath, and address, meant to be rented or lived in separately. If you want more living space for your own household, an addition is usually the right call; if you want a rentable second unit, that's an ADU. We build both and can help you decide.

Can you match a new addition to my existing Sherman Oaks home?+

Yes, and on Sherman Oaks' 1940s–60s ranch, mid-century, and Spanish homes that matters. A good addition shouldn't look bolted on — we match rooflines, stucco or siding texture, window styles, and floor heights so the new square footage reads as part of the original house. Tying a new foundation and framing cleanly into an older structure is exactly the kind of work a licensed general contractor handles and a handyman doesn't.

How long does a home addition take in Sherman Oaks?+

Plan on a few months of design and permitting before construction, then roughly 3–6 months to build depending on size and whether it's a ground-floor or second-story addition. Hillside lots south of Ventura and second stories that touch the foundation or roof structure take longer, and Hillside Ordinance review adds time in plan check. We give you a realistic combined design-permit-build schedule in the fixed-price proposal, not an optimistic guess. [VERIFY current timelines.]

Are you licensed and insured for home additions in Sherman Oaks?+

Yes. Right Image Builders holds active California license CSLB #1021284 and carries full general-liability and workers' compensation insurance. A home addition is structural work that must be engineered, permitted, and inspected — not something to trust to an unlicensed builder. Our office is in Valley Glen, just over the hill from Sherman Oaks, and we provide our license and insurance in writing before any work begins.
