Tarzana Home Addition Contractor | Right Image Builders

The Right Image Approach

More Room,
Without Moving

Outgrowing your Tarzana home doesn't have to mean buying a bigger one — with today's prices, 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 school district you already chose.

Right Image Builders is a licensed general contractor based in Valley Glen, a straight drive east on the Valley floor. 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.

Tarzana's lots shape what's possible. On the big, level flats north of Ventura Boulevard, there's genuine room for a large ground-floor addition or a primary suite. South of Ventura, in the upscale, semi-rural Tarzana hills, additions run into the City of LA Hillside Ordinance — grading, access, and drainage that have to be engineered from the start. The art either way is making the new square footage look original — matched rooflines, stucco, and windows — not bolted on.

What We Build

Ways to Add
Space in Tarzana

Room Additions

A new bedroom, family room, home office, or expanded living space extended off the existing house — new foundation, framing, roof, and systems, tied cleanly into your Tarzana home and permitted through LADBS. The big flat lots north of Ventura leave real room to do it.

Primary Suite Additions

Add the primary bedroom, walk-in closet, and en-suite bath an older Tarzana home may never have had — a high-return addition that transforms how the house lives. On a generous flats lot, there's often space for a genuinely large suite.

Second-Story Additions

When you want to keep the yard — or the lot is a hillside parcel to the south — 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.

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 & Hillside

Every addition is designed, structurally engineered, and permitted through LADBS. On hillside homes south of Ventura we also engineer and permit to the Hillside Ordinance — grading, retaining, drainage, and access — 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 — and on upscale Tarzana homes, that value is real money.

What Your Tarzana
Lot Will Allow

Every Tarzana addition starts with the parcel — and here, that means which side of Ventura Boulevard you're on. On the flats north of Ventura, including the Vanalden area, the lots are big and level: the rules are mostly floor-area ratio and the front, side, and rear setbacks you have to keep clear, and there's real room for a large ground-floor addition or primary suite.

South of Ventura, in the Tarzana hills, the lots are larger and more valuable, with an upscale, semi-rural feel — but they're governed by the City of LA Hillside Ordinance. Grading limits, retaining, drainage, haul routes, and access all have to be engineered and permitted correctly. Because Tarzana is City of Los Angeles, every addition is permitted through LADBS, and hillside plan check and structural review are more involved than a flats project.

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. [VERIFY exact FAR/setback figures with owner/current LADBS zoning.]

What It Costs

Tarzana 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, finishes, engineered and permitted — the large ground-floor additions Tarzana's flats lots allow.
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 conditions — hillside homes south of Ventura carry added grading and engineering cost. Ranges are for planning only; your fixed-price proposal follows the free consultation and zoning review. [VERIFY — owner to confirm current cost ranges before publish.]

How It Works

Three Steps.
Zero Surprises.

Free Consultation & Zoning Review

Tarzana Home Addition FAQ

Questions We
Hear in Tarzana

How much can I add onto my home in Tarzana?+

It depends on your lot size, zoning, and setbacks — and in Tarzana that varies a lot by where you are. On the big, level lots on the flats north of Ventura Boulevard, there's often real room for a large ground-floor addition or a primary suite up to the floor-area ratio the city allows, while keeping required front, side, and rear setbacks. South of Ventura, in the Tarzana hills, lots are larger but governed by the City of LA Hillside Ordinance, which brings grading, access, and haul-route rules into play. We pull your parcel's zoning at the free consultation and tell you exactly how much you can build. [VERIFY exact FAR/setback limits with owner/current LADBS zoning.]

Do you handle the permits and engineering for a home addition in Tarzana?+

Yes — a home addition is a permitted, engineered project from start to finish, and we manage all of it. Tarzana is City of Los Angeles, so the addition is permitted through LADBS. On hillside homes south of Ventura, we design and permit to the Hillside Ordinance — grading, retaining, drainage, and access — from day one. 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.

What's the difference between a home addition and an ADU?+

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. On Tarzana's larger lots, many owners have room for either — we build both and can help you decide.

Can you match a new addition to my existing Tarzana home?+

Yes, and on Tarzana's ranch, mid-century, and larger custom homes it 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. On the upscale, semi-rural homes up in the hills, that seamlessness is what protects the property's value. Tying a new foundation and framing cleanly into an existing structure is exactly the kind of work a licensed general contractor handles and a handyman doesn't.

How long does a home addition take in Tarzana?+

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 homes south of Ventura and second stories that touch the foundation or roof structure take longer, because the engineering and the Hillside Ordinance review are more involved. We give you a realistic combined design-permit-build schedule in the fixed-price proposal, not an optimistic guess. [VERIFY current timelines.]

Are you licensed and insured for home additions in Tarzana?+

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 — and on a Tarzana hillside lot it also has to satisfy the Hillside Ordinance — not something to trust to an unlicensed builder. Our office is in Valley Glen, a straight drive east, and we provide our license and insurance in writing before any work begins.
