More Room,
Without Moving
Outgrowing your Studio City home doesn't have to mean buying a bigger one — in a media-industry neighborhood where a Ventura Boulevard address holds its value, 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, 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 west of Studio City. 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.
Studio City homes are mostly mid-century and traditional, which shapes what's possible: flatter lots north of Ventura in areas like Colfax Meadows and the Silver Triangle take ground-floor additions and second stories well, while the hillside lots to the south toward Fryman Canyon demand engineered foundations and careful access. The art is in making the new square footage look original — matched rooflines, stucco, and windows — not bolted on.

Ways to Add
Space in Studio City
Ground-Floor Room Additions
A new bedroom, home office, family room, dining expansion or bump-out extended off the existing house — new foundation, framing, roof and systems, tied cleanly into your Studio City home and permitted through LADBS.
Primary Suite Additions
Add the primary bedroom, walk-in closet, and en-suite bath these mid-century homes were rarely built with — a high-return addition, finished to the upscale standard the neighborhood expects, that transforms how the house lives.
Second-Story Additions
When the lot is tight or you want to keep the yard, we build up — a common move in Studio City. Second stories require careful structural engineering to carry the new load on the existing foundation, exactly the work a licensed contractor engineers and permits. Not sure the house can carry a second floor? Start with our guide to second-story additions in Los Angeles.
Hillside Additions
On the slopes south of Ventura toward Fryman Canyon, adding on means engineered foundations — caissons or grade beams — plus grading and access planning under the city's hillside rules. This is precisely where a licensed, insured GC earns its keep.
Engineering & Permits
Every addition is designed, structurally engineered, and permitted through LADBS. We coordinate the architectural and structural plans, manage plan check — including hillside review where it applies — 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 Studio City
Lot Will Allow
Every Studio City addition starts with the parcel. Most homes here sit on mid-century 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. 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.
Because Studio City is City of Los Angeles, additions are permitted through LADBS. The homes on the hillside blocks south of Ventura, toward Fryman Canyon and Laurel Canyon, also fall under the city's hillside rules — engineered foundations, grading, height limits, and tighter street access that make experienced plan management essential. That's work we handle regularly from our Valley Glen shop, a short drive west.
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 — before you spend a dollar on design.
Where you are in Studio City shapes the addition. On the flats north of Ventura — Colfax Meadows, Woodbridge Park and the blocks around Tujunga Village — lots are mostly level, mid-century R1 parcels where a ground-floor room addition or a primary suite off the back is straightforward, and a second story is the usual answer when the yard is small. South of Ventura — the Silver Triangle, the Fryman Canyon and Laurel Canyon foothills and the streets climbing toward Mulholland — many parcels are designated Hillside Area under the City's Baseline Hillside Ordinance, and some sit in a Very High Fire Hazard Severity Zone. Additions there need engineered foundations, grading and drainage design, hillside height and floor-area checks, and fire-rated exterior assemblies where the zone applies. We confirm the Hillside Area and fire-zone status of your specific parcel at the free consultation, before design starts.
Studio City Home Addition
Cost Ranges
| Addition Type | Typical Range | What's Involved |
|---|---|---|
| Bump-Out | $75K–$145K | A few hundred square feet — kitchen or dining expansion, mudroom — with new foundation, framing, and matched exterior. |
| Room / Suite Addition | $145K–$290K | A full room or primary suite — foundation, framing, roof, systems, upscale finishes, engineered and permitted. |
| Second Story | $290K–$520K+ | Adding a full upper level — significant structural engineering to carry the load, plus stairs, systems, and full finishes. |
Additions vary widely with size, finishes, and structural or hillside conditions. Ranges are for planning only; your fixed-price proposal follows the free consultation and zoning review. The biggest drivers are 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 — see how the Los Angeles planning ranges are built.
How Long a Studio City
Addition Takes
Most Studio City additions take a few months of design and permitting before construction, then roughly three to six months to build for a ground-floor addition and longer for a second story or a hillside foundation. The exact schedule depends on scope, LADBS plan-check timing, whether hillside review applies, and the condition of the existing structure.
Preconstruction. Architectural plans and structural engineering come first, then LADBS plan check through the Valley office. Hillside parcels south of Ventura add grading, drainage and sometimes geotechnical items to the submittal, so allow more time there than on a Colfax Meadows flat lot.
Construction. Foundation and framing, roof tie-in, rough electrical, plumbing and HVAC with inspections at each stage, then insulation, drywall, exterior match and finishes, and the final inspection that closes the permit. We give you one combined design-permit-build schedule in the fixed-price proposal rather than an optimistic guess.
Three Steps.
Zero Surprises.
Free Consultation & Zoning Review
We visit your Studio City home, pull the parcel's zoning, and tell you honestly what you can build — square footage, height, setbacks, and any hillside factors — and which addition fits your goals and budget.
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.
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.
Choosing a Room Addition
Contractor in Studio City
Verify the license first. Go to cslb.ca.gov, choose "Check a License" and enter the number — ours is 1021284. Confirm it is active, that the classification covers structural work, and that a contractor's bond and workers' compensation are on file. Ask for general-liability and workers' comp certificates in writing.
An addition is structural, so ask who is responsible for the plans and engineering, who pulls the LADBS permit and closes it at final inspection, and — the Studio City question — how hillside review will be handled if your lot is south of Ventura. A contractor who has not asked which side of the boulevard you are on has not priced your project. Insist on a written fixed-price contract with an itemized scope, allowances spelled out, written change orders, and a payment schedule that follows completed work; California caps the down payment at $1,000 or 10 percent of the price, whichever is less.
Finally, ask how the new structure will be tied into the old one — foundation, roofline, stucco and floor heights — and who manages the schedule day to day. We are in the LADBS Van Nuys office regularly from our Valley Glen shop, which keeps a Studio City addition moving.
