Right Image Builders is a licensed home addition contractor serving Culver City — Carlson Park, Culver Crest, Blair Hills, Sunkist Park and the Clarkdale and McManus blocks — the room addition contractor to call when a 1920s–50s bungalow or ranch on a 5,000–6,500 sq ft lot needs one more bedroom, a primary suite or a second story. We build rear room additions, suites and second-story expansions, engineered and permitted through the City of Culver City Building Safety Division at City Hall, under one fixed-price contract; our crew is based in Valley Glen about 35–45 minutes away. Call (818) 210-4544.
A Culver City addition is usually a rear room or primary suite on a 1920s–50s bungalow or ranch, or a second story where the lot is tight and the zoning allows the height. Matching the roofline, the siding or stucco and the window proportions so the addition reads as original is most of the design work.
An addition on a 1920s–50s bungalow or ranch on a 5,000–6,500 sq ft lot is engineered from the foundation up: footings and a floor to match the house, framing and a roof tied into the existing roof line, plumbing to the lateral for a new bath, electrical on new circuits, HVAC extended or a dedicated mini-split, and stucco, trim and windows matched so the addition reads as original. The electrical service here is typically original 60- to 100-amp services in many bungalows and ranches; a new kitchen, an ADU or an EV charger usually means a 200-amp Southern California Edison service upgrade, which is why a 200-amp upgrade is often part of the project.
We are based in Valley Glen, about 35–45 minutes away, and the project lead who does your consultation runs the build and is on site at every milestone. The first thing we do is pull your parcel on the city's parcel map so you know the buildable square footage before you spend anything on drawings.
A new bedroom, family room or office off the back of a Culver City house, on its own foundation and roof, framed into the existing structure and permitted through Culver City Building Safety — the straightforward project on the neighborhood's lots.
Add the primary bedroom, walk-in closet, and en-suite bath these older homes were never built with — a high-return addition that transforms how the house lives without touching the yard footprint any more than needed.
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. If the lot is short, building up keeps the yard — our second-story addition guide covers the structural evaluation and roof work involved.
A Culver City bump-out adds a few hundred square feet to a kitchen, dining room or primary bath, with its own foundation, a matched roof line and exterior, permitted like any other addition.
Every addition is designed, structurally engineered, and permitted through Culver City Building Safety. We coordinate the architectural and structural plans, manage plan check, and carry the project to signed-off final inspection.
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.
Professional, licensed and insured, and we put that in writing at every step, because a remodel is a trust decision before it is a construction decision.
California general contractor license CSLB #1021284 (General Building B), active since 2016, with general liability and workers' compensation insurance. Check the license yourself at cslb.ca.gov before you sign anything, with us or anyone else.
The proposal lists what is demolished, what is built, which finishes are included and which permit covers it. If it is not written down, it is not in the job.
When walls, floors or roofs open up we photograph what is behind them and send you the pictures. Anything beyond the scope is priced in writing before the crew continues. You never find out from the invoice.
California law caps a home-improvement deposit at $1,000 or 10 percent of the contract, whichever is less. We follow it. Progress payments follow the work, and the final payment comes after your walkthrough.
We submit the plans, meet the inspector and close the permit. You get the closed-permit record, which is what a buyer, an insurer or an appraiser will ask for.
The people who estimate the job are the people who build it. No subcontractor hand-offs, no call center; your project lead answers the phone during the job and after it.
Culver City is its own city of about five square miles between Palms, Mar Vista and the Baldwin Hills, from the bungalow blocks around Downtown Culver City and the Culver Studios to the hillside streets of Culver Crest and Blair Hills. It permits its own work through the Building Safety Division at City Hall, 9770 Culver Boulevard, not LADBS, and our Valley Glen office is about 35–45 minutes away over the 405.
We pull the parcel at the first visit to confirm the zone, the setbacks and the floor-area limit, and on the hillside lots in Culver Crest and Blair Hills the fire-zone construction rules and the geology shape the design. A structural engineer evaluates the existing foundation and framing before a second story is drawn.
The addition is designed, structurally engineered and permitted through the City of Culver City Building Safety Division at City Hall, with inspections at foundation, framing, rough systems, insulation and final, and hillside review where the parcel requires it; the permit is closed at the end so the new square footage is on record when you refinance or sell.
Every room addition in Culver City gets one fixed, written price after a free on-site visit: we measure the house, check what the City of Culver City Building Safety Division requires for the lot and price the whole scope before you sign anything.
What moves the number is the scope you choose, the condition we find behind the walls and the finish level, never a surprise invoice: anything we uncover during the work is priced in writing before the crew continues, and the final payment comes after your walkthrough.
Setting a budget first? The room addition cost guide shows the current planning ranges by tier and neighborhood.
A Culver City home addition typically needs a few months of design, structural engineering and Culver City Building Safety plan check, then about three to five months of construction for a ground-floor addition and longer for a second story. On level lots the schedule is the most predictable part of the project; hillside parcels add grading and access review to plan check.
The sequence is plans and structural calculations, plan check at the Building Safety Division at City Hall on Culver Boulevard, then foundation, framing and roof tie-in, rough electrical, plumbing and HVAC with inspections at each stage, insulation, drywall, exterior match to the original stucco and finishes, and final inspection. Second stories add the structural evaluation and any reinforcement before framing. Your fixed-price proposal shows the whole schedule with realistic dates.
We visit your Culver City home, pull the parcel's zoning, and tell you honestly what you can build — square footage, height, setbacks — and which addition fits your goals and budget.
We produce architectural and structural plans, submit through Culver City Building Safety, and manage plan check — with a written fixed-price proposal set before construction begins.
One crew builds the addition to signed-off final inspection, matched to your existing home. Final payment is due only after your walkthrough approval.
Verify the license at cslb.ca.gov (ours is 1021284) — active, classified for structural work, bond and workers' compensation on file — and get insurance certificates in writing. Ask who prepares the plans, who engineers the structure and who takes the permit through the Building Safety Division at City Hall on Culver Boulevard and answers plan-check corrections; a contractor who knows that counter keeps a Culver City project on schedule.
Require a written fixed-price contract with an itemized scope, named allowances, written change orders and progress payments tied to completed work; California caps the down payment at $1,000 or 10 percent, whichever is less. Ask how the addition's foundation, roof and stucco will be tied into an older house so it reads as original, and who manages the schedule day to day.
Tell us what you want to add and we'll get back to you within 4 business hours. We'll confirm what your lot allows before you spend anything on design.
Prefer to talk it through?
We had a tiny living room that opened onto a covered patio we never really used. Right Image Builders designed and built a full family room addition in its place — 400 square feet, vaulted ceiling, skylights, and bifold doors to the garden. It completely changed how we live in this house. You can't tell it's an addition — it looks like it was always there.
Our full home remodel was a massive undertaking. Right Image Builders handled it all — demo, framing, plumbing, electrical, tile, painting. One contract, one crew, one point of contact. I cannot overstate how rare that is in LA.
They walked me through every permit requirement and handled it all themselves. The project finished on budget and exactly to spec. My BuildZoom contract check confirmed everything — these guys are top 1% for a reason.
