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

01

Room & Rear Additions

A new bedroom, family room or office off the back or side of the house, on its own foundation and roof, framed into the existing structure and permitted through LADBS — the most common Sherman Oaks project on the flats north of Ventura.

02

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.

03

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. Our second-story addition guide walks through the structural evaluation, the stair and the roof work involved.

04

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.

05

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.

06

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.

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.

Sherman Oaks splits at Ventura Boulevard. North of it — Chandler Estates, the streets around Fashion Square and the blocks toward Magnolia — lots are mostly flat R1 parcels with mid-century ranch and traditional houses, where a rear addition or a second story is planned around floor-area ratio and setbacks. South of Ventura the lots climb into the hills toward Longridge Estates, Stone Canyon and Mulholland; parcels designated Hillside Area come under the Baseline Hillside Ordinance (height, floor area and grading limits, plus access and haul-route requirements during plan check), and some are in a Very High Fire Hazard Severity Zone. Roofline integration matters on both sides — most of these homes have low-pitched or hipped roofs that an addition has to match or transition from cleanly. We confirm the Hillside Area designation for your specific parcel before we design.

What It Costs

Sherman Oaks Home Addition
Cost Ranges

Addition TypeTypical RangeWhat's Involved
Bump-Out$70K–$140KA few hundred square feet — kitchen or dining expansion, mudroom — with new foundation, framing, and matched exterior.
Room / Suite Addition$140K–$280KA 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. What moves a Sherman Oaks project within these ranges is square footage, foundation and structural work, second-story reinforcement, hillside or grading conditions, how far plumbing, electrical and HVAC have to move, and finish level; the Los Angeles cost guide breaks each driver down.

Timeline

How Long a Sherman Oaks
Home Addition Takes

A Sherman Oaks home addition typically runs a few months of design, engineering and LADBS plan check, then about three to five months of construction for a ground-floor addition and longer for a second story. Hillside Area parcels south of Ventura should expect additional review time for grading, access and structural items.

Flats north of Ventura. Plans and structural calculations, LADBS plan check, then foundation, framing, roof tie-in, rough trades and inspections, drywall, exterior match and finishes. A rear bedroom or family room is the quickest version; a primary suite with a new bathroom adds plumbing and HVAC scope.

Hills south of Ventura. Baseline Hillside Ordinance review, a grading plan and often a soils report come before plan check clears, and site access can slow deliveries and concrete pours. Second stories add the structural evaluation and reinforcement stage before framing. Every proposal shows the combined schedule with realistic dates.

How It Works

Three Steps.
Zero Surprises.

01

Free Consultation & Zoning Review

We visit your Sherman Oaks home, pull the parcel's zoning, and tell you honestly what you can build — square footage, height, setbacks, and any hillside rules — and which addition fits your goals and budget.

02

Design, Engineering & Permits

We produce architectural and structural plans, submit through LADBS, and manage plan check — with a written fixed-price proposal set before construction begins.

03

Build & Deliver

One crew builds the addition to signed-off final inspection, matched to your existing home. Final payment is due only after your walkthrough approval.

Before You Sign With Anyone

Choosing a Home Addition
Contractor in Sherman Oaks

Check the license at cslb.ca.gov (ours is 1021284): active, correctly classified for structural work, bond and workers' compensation on file. Ask for insurance certificates in writing. Then ask the Sherman Oaks question: is my parcel in a designated Hillside Area, and who handles that review? A contractor who cannot answer for the hills south of Ventura will be surprised in plan check — and you will pay for the surprise.

Insist on a written fixed-price contract with an itemized scope, named allowances, written change orders and progress payments that follow completed work; California caps the down payment at $1,000 or 10 percent, whichever is less. Ask specifically how the new roof will meet the old one and how the addition's floor height, stucco and windows will match — on Sherman Oaks' ranch and traditional homes that integration is what separates an addition that adds value from one that looks bolted on.

Sherman Oaks Home Addition FAQ

Questions We
Hear 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.
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.
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.
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.
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.
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.
For planning, Sherman Oaks bump-outs typically run about $70,000–$140,000, full room or primary-suite additions about $140,000–$280,000, and second stories about $280,000–$500,000 or more. Hillside parcels south of Ventura and premium finishes push projects toward the top of each range. These are planning ranges, not quotes — the fixed-price proposal follows the free on-site consultation and zoning review.
No. Both describe adding permitted, engineered square footage to your existing Sherman Oaks house — one new room, a suite, a bump-out or a full second story. The design, LADBS permit and construction process is the same; only the scope changes.
For parcels designated Hillside Area, yes. The Baseline Hillside Ordinance limits height, floor area and grading, and plan check can add access, haul-route and drainage requirements; some parcels are also in a Very High Fire Hazard Severity Zone. Additions are still very possible — they simply need to be designed to those rules from the start, which is what we do after confirming your parcel's designation.
