The Right Image Approach

More Room,
Without Leaving Lake Balboa

The typical Lake Balboa house is a 1,200–1,700 sq ft 1950s ranch on a 6,000–7,500 sq ft lot, three bedrooms and one or two small baths, and the room that is missing is almost always a primary suite or a second living space. A rear addition of 300–500 sq ft on its own foundation is the usual answer, with the roof line and stucco matched so it reads as original from the street; where the yard matters, a partial second story over the rear of the house keeps the lot.

An addition on a 1,200–1,700 sq ft 1950s tract house on a 6,000–7,500 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 60- to 100-amp panels from the 1950s; a 200-amp LADWP upgrade is usually part of a full kitchen, which is why a 200-amp upgrade is often part of the project.

We are based in Valley Glen, about 10–15 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 ZIMAS so you know the buildable square footage before you spend anything on drawings.

What We Build

Ways to Add
Space in Lake Balboa

01

Rear & Ground-Floor Room Additions

A new bedroom, family room or office off the back of a Lake Balboa ranch house, on its own foundation and roof, framed into the existing structure and permitted through LADBS — the straightforward project on the neighborhood's level 1950s lots.

02

Primary Suite Additions

Add the primary bedroom, walk-in closet, and en-suite bath these older tract homes were never built with — a high-return addition that transforms how the house lives without touching the yard footprint any more than needed.

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. If the lot is short, building up keeps the yard — our second-story addition guide covers the structural evaluation and roof work involved.

04

Bump-Outs & Kitchen Expansions

A Lake Balboa bump-out adds a few hundred square feet to a kitchen, dining room or primary bath: $60K–$120K, with its own foundation, a matched roof line and exterior, permitted like any other addition.

05

Engineering & Permits

Every addition is designed, structurally engineered, and permitted through LADBS. We coordinate the architectural and structural 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 Lake Balboa
Lot Will Allow

Lake Balboa is the west side of the old Van Nuys grid, from Victory Boulevard north to Sherman Way between the Sepulveda Basin and Reseda, with Anthony C. Beilenson Park and the lake itself at Balboa and Victory, Birmingham Community Charter High School on Haynes Street, and the Metro G Line busway station on Balboa Boulevard. Our office is in Valley Glen, about five miles east along Victory or Sherman Way, a 10–15 minute drive, and the LADBS counter that reviews every Lake Balboa permit is the Van Nuys Development Services Center on Van Nuys Boulevard, between the two.

Lake Balboa parcels are R1, flat, with no hillside or fire-zone overlay, which makes plan check the most predictable kind in the Valley; the rules that matter are the floor-area limit for the lot, the setbacks and the height limit for a second story, and we check all three on ZIMAS at the free consultation. The structural evaluation of the existing foundation and framing comes before any second-story design, and the permit runs through LADBS at the Van Nuys counter, ten minutes away.

The addition is designed, structurally engineered and permitted through LADBS (City of Los Angeles) at the Van Nuys Development Services Center, with inspections at foundation, framing, rough systems, insulation and final; the permit is closed at the end so the new square footage is on record when you refinance or sell.

Timeline

How Long a Lake Balboa
Home Addition Takes

A Lake Balboa home addition typically needs a few months of design, structural engineering and LADBS plan check, then about three to five months of construction for a ground-floor addition and longer for a second story. On level 1950s lots without hillside review, the schedule is usually the most predictable in the Valley.

The sequence is plans and structural calculations, plan check at the LADBS Lake Balboa office, 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.

How It Works

Three Steps.
Zero Surprises.

01

Free Consultation & Zoning Review

We visit your Lake Balboa 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.

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 Lake Balboa

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 LADBS Lake Balboa office and answers plan-check corrections; a contractor who knows that counter keeps a Lake Balboa 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 a 1950s house so it reads as original, and who manages the schedule day to day.

What Clients Say About
Our Room Addition Work

★★★★★

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.

Lake Balboa Home Addition FAQ

Questions We
Hear in Lake Balboa

It depends on your lot size, zoning, and setbacks. Most Lake Balboa 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. 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. Lake Balboa is City of Los Angeles, so the addition is permitted through LADBS, with Valley submissions handled at the Van Nuys Development Services Center on Van Nuys Boulevard. We coordinate the architectural plans and structural engineering, submit for plan check, and carry the project to signed-off final inspection. 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 a 1950s Lake Balboa tract home 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. Second stories and additions that touch the foundation or roof structure take longer. We give you a realistic combined design-permit-build schedule in the fixed-price proposal, not an optimistic guess.

Yes. Right Image Builders is a licensed California general contractor, CSLB #1021284, with general liability and workers' compensation insurance; verify the license in minutes at cslb.ca.gov under "Check a License" and ask us for the insurance certificates. The Lake Balboa estimate is free and on site, done by the project lead who will run the job, and the itemized fixed-price proposal follows within 3–5 business days.

Lake Balboa is City of Los Angeles, so the addition is permitted through LADBS, and Valley submittals are handled at the Van Nuys Development Services Center on Van Nuys Boulevard. Plan check covers structural, mechanical, electrical, plumbing and energy compliance, and LADBS inspects each stage of construction. We prepare the plans, submit, clear corrections and close the permit.

Lake Balboa room addition cost (2026): Bump-Out $60K–$120K; Room / Suite Addition $120K–$250K; Second Story $250K–$450K+. Plan on 2–4 months of design, engineering and plan check, then 3–6 months of construction. The exact figure depends on size, finishes and structural work; after the free on-site visit you get an itemized fixed price in writing.

Usually, after a structural evaluation. A licensed engineer checks whether the slab or raised foundation and the existing framing can carry a second floor and what must be reinforced; height, floor-area ratio and setbacks are checked against your R1 zoning. If it pencils, the second story is engineered, permitted at the Lake Balboa office and built while the ground floor stays protected.

Right Image Builders, a licensed general contractor (CSLB #1021284) based in Valley Glen about 10–15 minutes from Lake Balboa, builds room and home additions across the tract streets between Victory Boulevard and Sherman Way, the blocks around Beilenson Park and the lake, the Balboa Boulevard corridor under one fixed-price contract: design, permits through LADBS, and construction by one crew, with final payment only after your walkthrough. 5.0★ on Google (45 reviews) and 4.9★ on Angi (103 reviews).
