Paint Disposal and Recycling for San Francisco Businesses
Dimension collects paint from San Francisco businesses — latex and oil-based architectural paint, industrial and marine coatings, primers, stains, lacquers, thinners and aerosols. We handle the classification, the manifesting and the transport, and every pickup closes with documentation you can file.
Before you book, it is worth knowing that California has a free paint stewardship program, and for small volumes of ordinary architectural paint it is the better option. This page explains where that program stops and where a hauler becomes necessary, so you are not paying for something you could get free.
This is a business service. San Francisco residents should use the city’s household hazardous waste program, which takes paint at no charge.

Where PaintCare stops and a hauler becomes necessary
California’s paint stewardship law funds PaintCare, a network of free drop-off sites — mostly paint retailers — that accept leftover architectural paint. Every site takes up to 5 gallons per visit, and some take more. For a contractor finishing a small job with a few cans left over, that is the right answer and it costs nothing.
There are two limits that catch commercial generators. The first is volume-linked: if your business generates more than 27 gallons of hazardous waste per month, you may use PaintCare drop-off sites for latex paint only — not for your oil-based paint. The second is product-linked: sites do not accept aerosol coatings, solvents, leaking or unlabeled containers, or products labeled for industrial or non-architectural use. A 2023 California law adds aerosol coatings to the program, but on a timeline running to 2028.
Everything outside those limits is regulated hazardous waste, and in California that net is wide. Many paints are hazardous here regardless of whether they exhibit a federal hazardous characteristic, and there is no equivalent of the federal very-small-quantity-generator exemption — so an ID number and a manifest apply at any volume. Inside San Francisco, the Department of Public Health’s Environmental Health Branch is the CUPA that oversees this, and it requires generators to renew their plans 30 days before expiry, earlier than most California counties.
| Requirement | What it means for your business |
|---|---|
| Under 5 gallons of architectural latex | Take it to a PaintCare drop-off site. Free, and no paperwork. You do not need us for this. |
| Over 27 gallons of hazardous waste a month | You may still drop off latex at PaintCare, but not oil-based paint. Oil-based needs a permitted hauler and a manifest. |
| Aerosols, solvents and industrial coatings | Not accepted by PaintCare at all, and aerosols are not scheduled to enter the program until 2028. These are hazardous waste and need compliant collection. |
| Leaking, unlabeled or unknown containers | Refused at drop-off sites. We can take them, but they must be identified first — describe them in the quote and we will classify before pickup. |
| An EPA or California ID number | Required for any off-site hazardous waste shipment, at any volume. Issued by US EPA or DTSC. |

What Does Paint Disposal With Dimension Look Like?
- Scheduling: Tell us about your paint disposal needs — the type of paint (latex, oil-based, spray cans, primer), approximate quantity and container sizes, and your business location. Our AI-powered quoting system provides an instant price for most orders, or a Dimension team member will follow up within 1 business day for complex requests.
- Removal: A Dimension provider from our network of EPA-certified transportation partners arrives at your location, safely loads all paint containers, and handles proper labeling and manifesting for any hazardous materials. We handle everything from 1-gallon cans to 275-gallon totes.
- Compliance: Your paint waste is transported to licensed and approved treatment or recycling facilities. Latex paint goes to recyclers where it's reprocessed into new products. Oil-based paints and solvents go to certified hazardous waste facilities. You receive full documentation including diversion reports, manifests, and BOLs.
San Francisco questions, answered
Can my business just use PaintCare instead?
For small volumes of architectural latex paint, yes — and you should. PaintCare sites accept up to 5 gallons per visit at no charge, and there is no reason to pay for that.
Two things push you out of the program: generating more than 27 gallons of hazardous waste a month, which restricts you to latex only at drop-offs, and having products the program does not cover at all — aerosols, solvents, and anything labeled for industrial or non-architectural use.
Why can’t I drop off oil-based paint if I generate a lot of waste?
PaintCare limits businesses generating more than 27 gallons of hazardous waste per month to latex paint only at drop-off sites. Oil-based paint from those businesses has to move as hazardous waste, with an ID number and a manifest.
That threshold roughly tracks the small quantity generator line in the hazardous waste rules, which is why it exists. If you are near it, tell us your monthly volumes and we will help you work out which side you are on.
What about spray cans and aerosols?
PaintCare sites do not accept aerosol coatings. A 2023 California law brings them into the program, but implementation runs to 2028, so for now aerosols are hazardous waste needing compliant collection.
We take them. They need to be declared, because pressurized containers change how a load is packed and transported.
Is dried-out paint still hazardous waste?
It depends on the paint and how it was dried, so do not assume. California classifies many paints as hazardous regardless of federal characteristics, and the state also applies a stricter empty-container standard than federal rules.
If you have containers you believe are empty or fully cured, describe them and we will tell you whether they need to move as hazardous waste.
Who regulates paint waste for a San Francisco business?
The San Francisco Department of Public Health, Environmental Health Branch, as the city and county’s Certified Unified Program Agency. It handles generator oversight, Hazardous Materials Business Plans and inspections inside city limits.
San Francisco renews plans 30 days before the permit expiry date, which is earlier than most California counties — worth noting if you hold a permit here.
