What Remodeling and Construction Cost in Los Angeles: Our Published Budgeting Estimates

This page collects every cost estimate Green Design and Build has published, grouped by service, so you can see in one place what an ADU, a kitchen, a bathroom, a room addition, a re-roof or a whole-home renovation typically costs in Los Angeles. We are a licensed general contractor (CSLB #1110975) and design-build remodeler based in Van Nuys, serving homeowners across Los Angeles County, Orange County, Ventura County, western Riverside County and western San Bernardino County (Ontario, Rancho Cucamonga and neighbouring cities). Read the figures the way we use them: as budgeting estimates, not a price list. Real projects come in lower and higher than these ranges, and the only number that means anything for your house is a written proposal, which we deliver within about 48 hours of a roughly two-hour site visit.

Why we publish estimates instead of prices

Most contractors will not put a number on a website. We do, because a homeowner who knows that a detached ADU in Los Angeles runs into the hundreds of thousands of dollars, not tens of thousands, has a better first conversation with us and with everyone else they call. But a range on a page is not an offer. Every figure below depends on the house, the scope and the finishes, and on what we find when we open a wall in a 1950s Valley ranch house. So each table carries the same sentence, and we mean it every time: these are typical Los Angeles budgeting estimates, not a price list or a quote. Your project can come in lower or higher depending on the house, the scope and the finishes; the only real number is a written proposal after a site visit.

Who we are

Green Design and Build is led by Dekel Sofer. We hold a 4.7-star rating across 146 Yelp reviews and have completed hundreds of projects. We are a full-service residential general contractor and design-build remodeler for projects of every size, which is why this page runs from a $500 roof repair to a full second story: the same company, the same licence and the same proposal format apply to all of it.

How to read these numbers

All-in means all-in. Unless a table says otherwise, a range covers design, engineering where needed, permits and plan check, demolition, construction, the licensed trades and standard finishes. It does not cover furniture, landscaping, a pool or the cost of living somewhere else during the work.

Allowances. A proposal lists an allowance for anything you have not yet chosen: tile, plumbing fixtures, lighting, appliances, cabinet hardware. Pick above the allowance and the price rises by the difference; pick below it and it falls. The ranges here assume normal mid-range to upper-mid-range selections.

Contingency. On any home built before 1980 we recommend holding 15 to 20 percent of the budget in reserve for what demolition reveals: galvanized pipe, undersized panels, rotten subfloor, unbolted sill plates. The published examples below show why. A $22,000 bathroom refresh finished at about $28,500 after a failed tub overflow gasket had rotted the plate and subfloor, and a $180,000 detached ADU finished at $265,000 once a clay sewer line had to be rerouted and the panel upgraded.

Permits and fees. Permit and plan-check fees, school fees and utility charges are set by the city, the district and the utility, not by us. They appear as their own lines on a proposal and are passed through at cost.

Low end, high end. The low end of a range is a straightforward house, an easy site and stock finishes. The high end is a difficult site, structural work, relocated plumbing or custom finishes. A project can sit below or above either end.

ADUs and garage conversions

Scope Typical Los Angeles estimate What moves it
Garage conversion ADU $100,000–$200,000 Slab and footing condition, sewer line, electrical panel, whether the garage is rebuilt on its footprint
Detached ADU, about 500 sq ft $180,000–$260,000 Utility trenching distance, soil, panel upgrade, finish level
Detached ADU, 700–800 sq ft $225,000–$350,000 Same, plus a second bedroom and bathroom
Detached ADU, about 1,000 sq ft $300,000–$450,000+ Two-story or hillside design, fire-zone construction
Rule of thumb, detached ADU $300–$450 per sq ft all-in Difficult lots and higher-end construction run past $500 per sq ft
Timeline 6–12 months from first meeting to move-in City plan-check time, utility connections

These are typical Los Angeles budgeting estimates, not a price list or a quote. Your project can come in lower or higher depending on the house, the scope and the finishes; the only real number is a written proposal after a site visit.

Two published examples show the spread. Our ADU cost guide retells a detached ADU that started at $180,000 and finished at $265,000: the clay sewer reroute alone was about $14,000, the 200-amp panel upgrade $6,000 to $8,000, and the utility work added roughly three weeks. Our post on why ADU quotes vary so much between contractors follows a garage conversion that rose about 40 percent, from around $85,000 to $130,000, once the slab, panel and sewer were opened up. Service pages: ADUs and garage conversions; cost guide: garage conversion cost.

Kitchen remodeling

Scope Typical Los Angeles estimate What moves it
Cosmetic refresh, same layout $25,000–$40,000 Stock or semi-custom cabinets, counters, backsplash, paint, appliance swaps

Timeline Design and selections 3–6 weeks; permits 1–6 weeks; construction 4–8 weeks (same layout) or 8–12 weeks (layout or structural changes) Custom cabinets take about three weeks to manufacture

These are typical Los Angeles budgeting estimates, not a price list or a quote. Your project can come in lower or higher depending on the house, the scope and the finishes; the only real number is a written proposal after a site visit.

We do not start demolition on a kitchen until you have approved a 3D rendering and every selection, so the cabinets are in production when the old kitchen comes out.

Zoning decides the size before price does: on a standard City of Los Angeles R1 lot the front setback is 20 feet or the prevailing setback, sides 5 feet, rear 15 feet, and the Baseline Mansionization Ordinance caps floor area at 45 percent of the lot.

What we need to give you a real number

A range becomes a proposal after four things.

  1. A site visit of about two hours. We measure, photograph the existing plumbing, electrical and framing, check the panel, the sewer cleanout, the crawl space or slab, access for equipment and, for additions and ADUs, the lot’s setbacks and overlays.
  2. A scope in writing. What is in, what is out, and what is an allowance. If you have not chosen tile yet, the proposal says so and carries an allowance for it.
  3. Your selections, or a finish level. Stock, semi-custom or custom cabinets; quartz or stone; vinyl, fiberglass or clad wood. The finish level moves a kitchen from one tier to the next more than anything else.
  4. The house’s age and condition. Pre-1980 framing, galvanized pipe and a 100-amp panel are priced in from the start rather than discovered halfway through, and the contingency is set accordingly.

You receive the itemized proposal within about 48 hours of the visit. The visit and the proposal are free. Request one on our contact page, or read how design-build works at Green Design and Build first.

How payment works

California law caps the down payment on a home improvement contract at $1,000 or 10 percent of the contract price, whichever is less, and a contractor cannot collect payment for work not yet completed or materials not yet delivered. Our contracts follow that: a small deposit, then progress payments tied to completed milestones, with the final payment after the walkthrough and the last inspection. We offer financing programs through Synchrony, Service Finance and Home Run Financing; terms depend on the lender and your credit approval. Details are on our financing page and in our guide to contractor payment schedules in California. Our labor is covered by a one-year warranty.

Where we do this work

The ranges on this page are Los Angeles ranges, and the counties around it move them in predictable ways. In Los Angeles County and the San Fernando Valley, LADBS plan-check time and pre-1980 housing set the contingency; hillside and fire-zone lots add engineering and Chapter 7A materials. In Orange County, HOA architectural review in master-planned communities adds time before the city permit, and newer slab-on-grade homes make plumbing relocation the expensive item. Ventura County brings fire-zone construction in Thousand Oaks and Simi Valley and each city’s own building division. Western Riverside County and western San Bernardino County have newer tract housing, expansive soils that decide foundation design, and lower plan-check queues than the City of Los Angeles. See every area we serve.

Frequently asked questions

Are the figures on this page your prices?

No. The figures on this page are typical Los Angeles budgeting estimates, not a price list or a quote, and a real project can come in lower or higher depending on the house, the scope and the finishes. Green Design and Build publishes them so homeowners can budget realistically before the first call. The only real number for your home is a written, itemized proposal after a site visit.

Why do your estimates have such wide ranges?

The ranges are wide because the same scope costs very different amounts in different houses: a same-layout kitchen in a 1990s Irvine house and one in a 1952 Van Nuys ranch with galvanized pipe and a 100-amp panel are not the same job. Finish level moves the number as much as the house does. A written proposal narrows the range to a single figure by pricing your house, your scope and your selections.

What does “all-in” include?

All-in, on this page, means design, engineering where needed, permits and plan check, demolition, construction, the licensed trades and standard finishes. It does not include furniture, landscaping, a pool, a detached structure or the cost of living elsewhere during the work. Permit, school and utility fees are passed through at cost and shown as their own lines on the proposal.

How much contingency should I hold?

Green Design and Build recommends holding 15 to 20 percent of the budget in reserve on any home built before 1980. The published examples show why: a $22,000 bathroom refresh that finished at about $28,500 after a rotted subfloor was found, and a $180,000 detached ADU that finished at $265,000 after a clay sewer reroute and a panel upgrade. Newer homes need less, but no remodel of an occupied house should be budgeted to the last dollar.

How do I get an actual quote?

Request a free site visit through our contact page or by calling (800) 348-3050. We walk the property for about two hours, confirm the scope and your selections, and deliver an itemized written proposal within about 48 hours. The proposal lists what is included, what is excluded and what is an allowance, so you can compare it line by line with any other bid.

Do these estimates apply outside the City of Los Angeles?

Broadly, yes: the ranges on this page are typical for Los Angeles, and Green Design and Build works from the same estimates across Orange County, Ventura County, western Riverside County and western San Bernardino County. Local factors shift them: HOA review in Orange County master-planned communities, fire-zone construction in Ventura County and the hillsides, expansive soils in Corona and Ontario, and each city’s own plan-check times and fees. The site visit accounts for all of it.
