Los Angeles homeowners face a choice that doesn't exist in most other markets: the homes they love in the neighborhoods they want are often undersized for the way they actually live. Moving means competing in one of the country's most expensive real estate markets. Staying means figuring out how to make the space work. A room addition is how you stay — and get the space you actually need.
A room addition isn't a simple project. It requires a new foundation or foundation extension, structural framing that integrates with the existing building, a new roof section that matches or transitions from the existing, exterior finish that blends with the current facade, and all new MEP (mechanical, electrical, plumbing) extended from the main systems. It requires a building permit with structural engineering drawings. It requires inspections at every phase. Done wrong, it creates a structure that doesn't match the house, leaks at the connection point, and flags immediately on a home inspection when you sell.
Right Image Builders manages room additions from site assessment through Certificate of Occupancy. We coordinate licensed structural engineering drawings, handle all permit submittals and plan check responses with LADBS or your city's building department, build the addition with our in-house crew, and match the exterior finish to your existing home. The result is an addition that looks like it was always there — not an addition that looks like a box attached to the back of the house.
We work across all addition types: master suite additions with ensuite bathrooms, home office additions with dedicated exterior access, family room and great room expansions, second-story additions, sunrooms and enclosed patio additions, and in-law suite additions for multi-generational households. Each type has different structural requirements, setback implications, and zoning considerations in Los Angeles. We assess all of it at the site visit before you commit to anything.
Dedicated master bedroom and ensuite bathroom addition — the most-requested addition type in Greater LA. Includes new foundation extension, framing, roof, exterior matching, and all interior finishes: custom tile bathroom, walk-in closet, hardwood or engineered flooring, trim and paint. MEP extended from the main home's systems with dedicated circuits for the new bath. Typically 300–600 sq ft.
A dedicated workspace addition designed for remote work, client meetings, or professional practice — built outside the main living area noise envelope. Options include a separate exterior entrance for clients, mini-split HVAC for independent climate control, structured data wiring (Cat 6A, fiber pre-wire), and sound-insulated walls. Built as conditioned square footage — fully integrated with the home, not a converted shed.
Expanding the existing footprint to create an open great room — extending the rear of the home or converting a covered patio into conditioned space. Includes structural beam work where existing walls are removed, new roof framing, vaulted ceiling option, large-format sliding or bifold door systems (Fleetwood, NanaWall, LaCantina) to connect indoor and outdoor living, and all interior finishes to match or contrast the existing home.
Adding a complete second floor — or a partial second-story addition above an existing single-story portion — requires the most engineering of any addition type. We coordinate structural assessment of the existing first-floor framing and foundation, engineering design for the new floor system and lateral bracing, new roof structure, and stair integration into the existing floor plan. Second-story additions in LA also require Title 24 energy compliance and fire-rated floor-ceiling assemblies. Full scope, one contract.
Converting a covered patio or building a new sunroom addition — permitted conditioned space with full insulation, drywall, electrical, and HVAC. Aluminum or wood frame construction with insulated glass, operable windows, and optional sliding or bifold door systems. Not a prefab kit — a fully permitted, architecturally integrated addition that adds genuine square footage to your home and genuine value on appraisal.
A private suite for extended family — bedroom, full bathroom, separate living area, and kitchenette rough-in. Designed with a separate exterior entrance for privacy while staying connected to the main home. Compliant with LA County zoning for accessory living areas (distinct from an ADU — this is an addition to the primary structure, not a separate unit). Acoustic insulation between the suite and the main home is standard on every build.
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.

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.
A room addition in Los Angeles starts with a free on-site visit and ends with one fixed, written price that covers the whole scope, the permit from LADBS and the inspections, before any work begins.
The three things that change the price are the scope, what the house hides and the finishes you choose, and each is settled in writing before the crew moves on; final payment comes after your walkthrough.
If you want numbers before the visit, the room addition cost guide publishes the current planning ranges.
A senior member of our team walks the property, assesses the existing structure, reviews setbacks and zoning allowances, and gives you an honest scope and cost range before any design work begins.
We coordinate architectural and structural drawings, submit for permit, and deliver a fixed-price construction contract before breaking ground. No open-ended T&M on an addition.
One crew builds your addition from foundation to final paint. We hand you a seamlessly integrated addition with a closed permit — not an afterthought box attached to the back of your house.
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 himself. The project finished on budget and exactly to spec. My BuildZoom contract check confirmed everything — these guys are top 1% for a reason.

A fixed price, in writing, after the free on-site visit, not a running estimate. The scope is itemized line by line, the LADBS permit and inspections are inside it, and hidden conditions found during a Los Angeles job are priced in writing before any further work.

Free on-site consultation. Engineering and permits coordinated. Fixed-price construction contract before ground breaks.
Across Greater Los Angeles a room addition typically needs a few months of design, structural engineering and plan check before construction, then roughly three to six months of building for a ground-floor addition and longer for a second story. Hillside parcels, separate city jurisdictions and premium finishes extend the schedule; the fixed-price proposal shows realistic dates for your project.
Check the license at cslb.ca.gov — ours is 1021284 — for active status, the right classification, a bond and workers' compensation. Get insurance certificates in writing. Confirm the contractor is responsible for the architect, the structural engineer and the permit in the correct jurisdiction, and that the contract is written, fixed-price and itemized, with 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. Then ask how the new structure will be tied into the old one. Each city page below adds the local question that matters there.
Los Angeles is not one building department. Most of the Valley communities we serve are inside the City of Los Angeles and permit through LADBS; Burbank is its own city with its own Building & Safety Division; and Toluca Lake straddles the two. The jurisdiction sets the plan-check process, the fees, the hillside rules and the inspection calendar, so it is the first thing we confirm for your address.
Hillside Area parcels inside the City of Los Angeles are reviewed under the Baseline Hillside Ordinance, and additions on Burbank's R-1 Hillside parcels can require a Hillside Development Permit. Neither applies to every property; we check the designation for your specific parcel before design.
