How Much Does Epoxy Flooring Cost in San Francisco, CA? (2026 Guide)
Each epoxy flooring cost on this page is a national figure, printed by a named price survey and dated by the page that carried it. None of those surveys prices a job in San Francisco or in Daly City, South San Francisco, San Bruno or Pacifica, and none says by how much a Bay Area floor differs, so no local markup has been added to any row. Treat each row as one survey's range for its own scope. HomeGuide, Angi, HomeAdvisor and the rest do not agree with one another, and a blend of their figures would be a number none of them printed. What a particular floor costs is settled by the installer's written quote, prepared once the slab has been measured and checked for moisture; the garage floor epoxy page explains the systems these ranges pay for.

What Changes the Price?
Floor size: The surveys put size first. HomeAdvisor's June 2026 update calls it "the primary factor driving the overall cost", and Angi's August 2026 update ties more square footage to more material. Small floors cost more per foot: HomeGuide's February 2026 national polished concrete survey says pricing often runs $8 to $15 or more a square foot on jobs below 1,000 square feet and may fall to $3 to $6 on spaces above 5,000 square feet, and several surveys print minimum charges.
Resin type: The gallon price moves with the resin. HomeGuide's February 2026 national survey lists water-based epoxy at $40 to $100 a gallon and solid epoxy at $70 to $150, and Angi's August 2026 update says resin type and floor size "drive most of your epoxy project cost," along with surface preparation. HomeGuide's lifespan wording differs by resin too: 3 to 5 years for water-based, 10 to 20 for solid.
Slab condition: Repairs come before any coating. HomeGuide's February 2026 national epoxy survey says to repair or fill cracks first and that, "If the damage is widespread," you may need to resurface, which its resurfacing page prices at $3 to $7 a square foot. HomeGuide's November 2024 concrete coating survey puts moisture testing at $50 to $300. On bay fill or an old ground-story garage slab, ask what the test and the crack survey found before comparing quotes.
Decorative finish: Flake, metallic tint and custom images cost extra, and the surveys price them only as add-ons. HomeGuide's February 2026 epoxy survey names those additions without a figure, This Old House's March 2026 national add-on table lists a metallic epoxy floor between $5 and $12 a square foot, and HomeGuide's November 2024 polyaspartic survey says decorative flakes, custom colors or patterns can add $0.50 to $2.00 a square foot.
Labor share: Labor is a large share wherever a survey states one. Angi and HomeAdvisor put it at 33% to 60%, and HomeGuide's December 2024 garage coating survey at about 50% to 70%. Trade wages in the San Francisco-Oakland-Fremont metro run above the national medians: O*NET's pages, from BLS 2025 wage data, give cement masons and concrete finishers there a median of $36.53 an hour against $27.41 nationwide. Those are wages paid to workers, not prices charged for a floor.
Access and timing: Clearing the space and waiting out the cure have costs of their own. Angi's August 2026 national update prints at least $100 for moving or short-term storage, and Forbes Home's February 2025 update $20 to $450 a month for a storage rental. HomeGuide's February 2026 survey says polishing hard-to-reach areas such as basements may cost 10% to 30% more; ask whether a narrow garage door or a stair changes the quote.
The number that matters is the written quote for your own floor. Line two quotes up and check that each names the moisture test and its reading; the preparation, such as diamond grinding or shot blasting to a stated concrete surface profile (the roughness ICRI 310.2R grades from CSP 1 to CSP 10); every product and its film thickness in mils; crack and joint repair; the tax treatment; and the cure and traffic times. A request through the quote form is passed to an independent installer holding a California contractor license, so check that license on CSLB's site before signing.
What the national surveys print, and why San Francisco is missing
The rows come from national cost pages, each dated by what the page showed when it was read. HomeGuide dated its epoxy flooring page February 3, 2026; Angi's carried an August 2026 update, HomeAdvisor's a June 2026 one and This Old House's a March 2026 one; Fixr's was updated January 31, 2025, Forbes Home's in February 2025 and Bob Vila's on April 26, 2024. Angi and HomeAdvisor describe their figures as drawn from surveys of thousands of their own customers, and Bob Vila draws on Angi, HomeAdvisor and HomeGuide by its own list of sources, so its rows are not independent of theirs. Angi's national epoxy page has no table by city, and no page in this set prints a figure for San Francisco. The surveys differ, so each range is read within its own page.
A price parity does not fill that gap. The Bureau of Economic Analysis says regional price parities measure price levels "across states and metropolitan areas for a given year" as a percentage of the national level, over all consumer goods and services, housing rents included, adding that "Housing rents are often the main driver in differences in RPPs." In BEA's December 2024 release, covering 2023 and since superseded, the San Francisco-Oakland-Berkeley metro stood at 118.2 against 100.0 for the nation, with goods at 117.2 and housing at 200.2, and California stood at 112.6; BEA's February 19, 2026 release puts California at 110.7 for 2024. None of that prices a floor coating, and no survey applies it to one, so a national range multiplied by a parity is an estimate of your own making, not a published price. The San Francisco numbers page lists the parities beside the wage data.
What a floor your size works out to, and the minimum charges
HomeGuide's epoxy page prints no total for a 12x12 room or for 1,000 square feet, so those figures are arithmetic. Take HomeGuide's national $4 to $10 for each square foot: a 12x12 room (144 square feet) works out to $576 to $1,440; a two-car garage measuring 20 by 20, which is 400 square feet, to $1,600 to $4,000; and 1,000 square feet to $4,000 to $10,000. This Old House's national rate for hired work, $3 to $12, makes the same 1,000 square feet $3,000 to $12,000. These are multiplications, not survey figures. Some national pages do print totals of their own: HomeGuide's December 2024 garage coating table, for one, gives a 20x20 two-car garage $1,600 to $4,800, and Fixr's January 2025 page gives an average basement of about 1,000 square feet in thick-coat epoxy $10,000 to $15,000.
Those multiplications understate small jobs, because several national surveys print minimum charges. On concrete resurfacing, HomeAdvisor's June 2026 update warns that "Some contractors may also charge a minimum fee of $500 to $1,000," and Bob Vila's April 2024 garage page says "some contractors require a $500 to $1,000 minimum charge." HomeGuide's November 2025 pages add that "Most contractors charge a minimum job fee of $300 to $700 or more for concrete leveling" and that for sealing "Minimum service fees are $150 to $300." The license line sits nearby: CSLB's small-job exemption ends at $1,000 in combined labor and materials, and every garage row in the table above starts over that amount, so at survey prices a garage floor needs a contractor license.
How to read a quote and a contract in California
Sales tax on a floor job follows the contract type, as the California Department of Tax and Fee Administration describes it. CDTFA Publication 9 (February 2025) says "Construction contractors are generally the consumers of materials" and that tax applies to the cost of materials to the contractor. Under a lump sum contract, Publication 9 treats the contractor as the consumer of the materials it furnishes and installs; a contract that bills the customer tax computed on marked-up materials makes the contractor their retailer. The publication names linoleum, floor tile and carpet among floor coverings and does not mention floor coatings. CDTFA's rates operative October 1, 2026 are 8.625% in San Francisco and 9.875% in Daly City, South San Francisco, San Bruno and Pacifica, and the jobsite sets the district tax. The written quote should state its tax treatment, and the final word belongs to CDTFA or a tax professional.
The contract terms come from the Business and Professions Code. A written home improvement contract is required once the price passes $500 (section 7159(b)), and it must carry the contractor's license number and the contract price, describe the project and its significant materials, and print the notice that the down payment "MAY NOT EXCEED $1,000 OR 10 PERCENT OF THE CONTRACT PRICE, WHICHEVER IS LESS." Section 7159.5 forbids any later payment that runs ahead of the work performed or material delivered, and lets you ask for a lien release after each payment. Unless the statute excepts your contract, as it does one negotiated at the contractor's own place of business, you may cancel by midnight of the third business day after receiving a signed and dated copy, or the fifth if you are 65 or older. The hiring guide explains each term.
Epoxy Flooring Pricing Questions
What does 1,000 square feet of epoxy flooring cost?
It depends on the survey, and every figure is national. Fixr's January 2025 page prints a 1,000-square-foot epoxy example: an average basement of that size in thick-coat epoxy at $10,000 to $15,000. Otherwise it is arithmetic: multiply 1,000 square feet by the $4 to $10 per square foot in HomeGuide's February 2026 survey and you get $4,000 to $10,000; by the $3 to $12 that This Old House's March 2026 update gives for hired work, $3,000 to $12,000. A commercial floor needing a 100% solids system runs $12 or more a square foot in HomeAdvisor's June 2026 update.
What does a 20x20 epoxy garage floor cost?
HomeGuide's December 2024 garage floor coating table, which covers coatings in general rather than epoxy alone, prints a 20x20 two-car garage of 400 square feet at $1,600 to $4,800, a national figure like every other here. Multiplying the same 400 square feet by HomeGuide's February 2026 epoxy rate of $4 to $10 gives $1,600 to $4,000, which is arithmetic rather than a survey figure. HomeGuide's November 2024 table prices 400 square feet of polyaspartic at $2,000 to $4,800; the polyaspartic floor coating page compares the two systems. A garage here is priced from the installer's measurement, moisture test and written quote.
What does each survey print for a two-car garage?
Each survey answers differently, and all of them nationally. Forbes Home (February 2025) prints a two-car average of $2,200, inside a range running from $1,300 at the low end to $3,100 at the high. HomeGuide (February 2026) sizes the two-car garage at 400 to 576 square feet and prices it from $1,600 up to $5,800. Angi and HomeAdvisor both use 500 square feet and print $1,500 up to $6,000. HomeAdvisor's $2,526 average is for epoxy floors of every kind, not two-car garages alone. The surveys' two-car garages run from 360 square feet (Bob Vila, This Old House) to 576 (HomeGuide), so measure yours before comparing.
Is it expensive to epoxy a floor?
Against the other finishes the surveys price, epoxy sits in the middle. HomeGuide's December 2024 national garage coating page puts garage floor sealing between $1 and $3 a square foot and painting between $2 and $4, against $4 to $10 for epoxy and $5 to $12 for polyaspartic, and HomeGuide's February 2026 survey puts premade DIY kits at $200 to $700. The cheaper finishes carry shorter lifespan wording in that page's comparison table: 1 to 3 years for acrylic sealers and 1 to 5 years for garage floor paint.
Is an epoxy garage floor worth the money?
That turns on the slab and how you use the garage, not on resale value. Angi's August 2026 update says an epoxy floor "will not directly increase your home's value," and HomeAdvisor's June 2026 update says epoxy floors "don't raise a home's formal appraisal value." What the money buys is a sealed, cleanable surface whose life, in the surveys' and makers' words, depends on preparation, moisture and care. On a damp or settled slab, part of the budget belongs to the moisture test and the repair before any coating.
How much can an installer ask for up front in California?
No more than 10 percent of the contract price or $1,000, whichever is less, under Business and Professions Code section 7159.5(a)(3). After that, the contractor may neither request nor accept payment beyond the value of the work performed or material delivered. A contractor who furnishes a performance and payment bond, or another arrangement the registrar approves, is exempt from those limits under section 7159.5(a)(8). CSLB's consumer advice adds: "Don't pay cash, and don't let the payments get ahead of the work."
