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.

Ways to Add
Space in Sherman Oaks
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.
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. Our second-story addition guide walks through the structural evaluation, the stair and the roof work involved.
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.
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.
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. 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.
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.

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.
