California’s VOC limits are set by the California Air Resources Board (CARB) under two programs: the Consumer Products Regulation, which covers household and personal care items, and the Architectural Coatings program, which covers paints, stains, primers, and similar materials applied to buildings and structures.1California Air Resources Board. Consumer Products Program2California Air Resources Board. Architectural Coatings Local air districts can adopt tighter limits, and when both apply, the product has to meet the lower of the two. Getting the numbers wrong exposes a manufacturer to criminal fines up to $25,000 per day for negligent violations and civil penalties up to $40,000 per day where a violator knew about the problem and failed to correct it.
Who Sets and Enforces the Limits
CARB writes the statewide floor. Local Air Quality Management Districts and Air Pollution Control Districts enforce within their territories and often go further. The South Coast AQMD, covering greater Los Angeles, is the clearest example: its Rule 1113 required nonflat coatings to meet 50 g/L back in February 2016, years ahead of the statewide standard.3South Coast Air Quality Management District. Rule 1113 Table of Standards If you sell into a district with its own rule, check both the CARB limit and the local one, and comply with whichever is stricter.
What Products Are Covered
The Consumer Products Regulation reaches well over a hundred product categories: aerosol sprays, glass cleaners, furniture polish, hairspray, deodorant, adhesives, automotive brake cleaners, insecticides, and more.4Legal Information Institute. California Code of Regulations Title 17 Section 94509 – Standards for Consumer Products If you manufacture, distribute, or sell any of these in California, the product must meet the VOC limit for its category at the time of sale.
The Architectural Coatings program covers materials designed for field application to stationary structures, portable buildings, pavement, and curbs. That means interior and exterior paints, stains, varnishes, primers, sign paints, traffic markings, and industrial maintenance coatings.2California Air Resources Board. Architectural Coatings
How the Limits Are Measured
The two programs use different units, and mixing them up is a common compliance mistake.
Architectural coatings are measured in grams of VOC per liter of coating, excluding water and exempt compounds. This is the “VOC regulatory” figure, sometimes called “VOC, less water and exempts” in local district rules.5California Air Resources Board. Table of VOC Limits A high-water coating can look low-VOC by total weight and still fail the regulatory calculation, because the water volume drops out of the denominator.
Consumer products are measured as a weight percentage. CARB Method 310 is the approved test protocol, and it subtracts exempt compounds from total volatile material.6California Air Resources Board. Method 310 – Determination of Volatile Organic Compounds (VOC) in Consumer Products Alternative test methods require written approval from CARB’s Executive Officer.
Common Category Limits
Limits vary widely by category. A few architectural coating examples under the current CARB Suggested Control Measure:
- Flat coatings: 50 g/L
- Nonflat coatings (satin, semi-gloss, gloss): 50 g/L, effective January 1, 2022
- Industrial maintenance coatings: 250 g/L
The nonflat number caught manufacturers off guard. Before 2022, the CARB statewide limit was 100 g/L. The 2019 Suggested Control Measure cut it in half to match the flat coatings standard.7California Air Resources Board. 2019 CARB Suggested Control Measure for Architectural Coatings Product formulated to the old 100 g/L limit is no longer compliant unless it qualifies for sell-through. Industrial maintenance coatings carry a much higher 250 g/L limit, reflecting the performance demands of corrosion- and chemical-resistant applications.8LA County Public Works. 2026 VOC Limits for Architectural Coatings
On the consumer products side, dry shampoo currently carries a 55 percent by weight VOC limit, tightening to 50 percent on January 1, 2029.9California Air Resources Board. Consumer Products Regulation Initial Statement of Reasons Multi-purpose lubricants have a 10 percent by weight limit, with an alternate compliance option allowing up to 25 percent if the formulation also meets a reactivity limit of 0.45 grams of ozone per gram of product.1California Air Resources Board. Consumer Products Program The full Table of Standards in Section 94509 gives the specific limit and effective date for every regulated consumer product category.
What Doesn’t Count Against the Limit
Not every volatile compound is counted. The EPA maintains a list of compounds exempted from the VOC definition because they contribute negligibly to ozone formation. Commonly used exempt solvents include acetone (exempted in 1995), methylene chloride, methyl acetate, t-butyl acetate, parachlorobenzotrifluoride (PCBTF), and dimethyl carbonate.10US EPA. Complete List of VOC Exemption Rules Formulators regularly swap exempt solvents for regulated ones to bring products into compliance without sacrificing performance.
A separate exclusion applies to Low Vapor Pressure VOCs (LVP-VOCs) in consumer products. Under federal standards, a compound is excluded from the VOC calculation if it has a vapor pressure below 0.1 millimeters of mercury at 20°C, contains more than 12 carbon atoms when vapor pressure is unknown, or has a melting point above 20°C and does not sublime.11eCFR. 40 CFR Part 59 Subpart C – National Volatile Organic Compound Emission Standards for Consumer Products CARB uses a similar LVP-VOC concept, which lets many heavier solvents like mineral spirits and certain glycol ethers drop out of the percentage calculation.
Sell-Through for Old Stock
When CARB tightens a limit, products already made under the old standard don’t turn illegal overnight. The regulations allow a sell-through period, typically three years after the compliance deadline, during which pre-existing stock can still be sold.12Legal Information Institute. Cal. Code Regs. Tit. 17, Section 94510 – Exemptions This is why the date code on every container matters. It proves when the product was manufactured and whether it qualifies. Product without a legible date code loses the benefit, and enforcement investigators look for exactly that gap.
Labeling and Recordkeeping
Every consumer product subject to Section 94509 must display the day, month, and year of manufacture, or a coded equivalent, legibly on the container or package. If you use a date code, you have to file the code explanation with CARB so inspectors can read it.13Legal Information Institute. Cal. Code Regs. Tit. 17, Section 94512 – Administrative Requirements
Architectural coating containers carry more. The label must show the manufacture date or date code, the manufacturer’s thinning recommendation (or a statement that the coating should be applied without thinning), and the VOC content in grams per liter as supplied. Specialty categories carry extra label statements: industrial maintenance coatings must say “For industrial use only” or “Not for residential use,” rust preventative coatings must note “For Metal Substrates Only,” and clear brushing lacquers must include “For brush application only” and “This product must not be thinned or sprayed.”
On the records side, manufacturers must keep formulation data and test results sufficient to demonstrate compliance. Manufacturers using the multi-purpose lubricant alternate option must retain at least three years of production records and produce them to CARB’s Executive Officer on request.14Legal Information Institute. Cal. Code Regs. Tit. 17, Section 94513 – Reporting Requirements CARB also runs periodic surveys of consumer products and architectural coatings manufacturers, collecting sales volume and formulation data.15California Air Resources Board.

Compliance Alternatives
Three options exist when a straightforward reformulation isn’t practical.
Innovative Products Exemption
A manufacturer can seek an exemption from the Section 94509 limits by showing, with clear and convincing evidence, that a product’s design, delivery system, or formulation produces lower total VOC emissions than a representative compliant product in the same category and form.16Legal Information Institute. Cal. Code Regs. Tit. 17, Section 94511 – Innovative Products It’s most useful for aerosols where a new delivery system achieves better coverage with less chemical released.
Alternative Control Plan
The Alternative Control Plan, set out in Sections 94540 through 94555 of Title 17, lets a manufacturer exceed the limit on some products by cutting emissions on others enough to hit the same portfolio total.4Legal Information Institute. California Code of Regulations Title 17 Section 94509 – Standards for Consumer Products It functions as an emissions budget and is generally used by large manufacturers with broad product lines.
Variance
Under Section 94514, a manufacturer facing extraordinary circumstances that make compliance technologically or economically infeasible can apply to CARB for a temporary variance. The applicant submits a written request explaining the grounds and a compliance plan with a target date, which under parallel federal rules cannot exceed five years from the date the variance is granted.11eCFR. 40 CFR Part 59 Subpart C – National Volatile Organic Compound Emission Standards for Consumer Products Variances come with incremental milestones, and missing any condition revokes the variance automatically. They’re rare in practice.
Penalties for Noncompliance
CARB and local air districts enforce through market surveillance: investigators buy products off shelves and test them using CARB Method 310 or an equivalent approved method.17California Air Resources Board. Consumer Products Laboratory Test Methods Consequences run on two tracks.
On the criminal side, California Health and Safety Code Section 42400.1 makes negligent emission of an air contaminant in violation of CARB or district rules a misdemeanor punishable by a fine up to $25,000, up to nine months in county jail, or both. Each day of continuing violation is a separate offense, so product left on shelves for weeks stacks liability. If the negligent emission causes great bodily injury or death, the fine ceiling rises to $100,000 and the jail term extends to a year.18Justia Law. California Health and Safety Code 42400-42410
On the civil side, Section 42402 imposes penalties of up to $5,000 per day for operating a source of air contaminants in violation of CARB or district rules, with no need to prove intent or negligence. Where the violator knew about the emission and failed to take corrective action within a reasonable time, Section 42402.2 raises the ceiling to $40,000 per day. A knowing violation that causes great bodily injury or death carries a maximum per-day civil penalty of $250,000.19California Legislative Information. California Health and Safety Code Section 42402.2 CARB also negotiates settlements calculated in part by estimating the tonnage of excess VOCs released, which can produce large figures even when a product exceeds its limit by a modest margin.
