How to Sell Pottery from a Home Studio Legally in California
To sell pottery from a home studio in California legally you need a seller's permit, a city business tax certificate, zoning that allows the work, and lead and cadmium compliance for food-use ware.
What to take away
- California requires a seller's permit from the California Department of Tax and Fee Administration (CDTFA) before you make a taxable sale of pottery. Registration costs nothing, and you must file returns even in months with no sales.
- Your city or county decides whether a home pottery business is allowed at all, through zoning and a home occupation permit.
- Post your seller's permit where you sell, as California requires for each place of business.
- Pottery for food use must meet lead and cadmium rules, and California's Proposition 65 can require a warning.
- Your homeowner's policy often excludes business stock and kiln losses, so confirm coverage before the first firing you intend to sell.
Who has jurisdiction over a home pottery sale
Three layers of government touch a California home studio, and each one asks a different question.

The CDTFA handles sales tax. It issues the seller's permit and collects the tax you charge buyers. You can apply online on the CDTFA website at no cost, or request the printed application form. The CDTFA replaced the Board of Equalization for this work, so older guides that name the BOE are out of date. The governing law is the California Revenue and Taxation Code.
Your city or county handles zoning and the business tax certificate, which many cities call a business license. A home occupation permit is the usual zoning tool, and pottery is sometimes treated as a light manufacturing use rather than a home office.
If you form an LLC or corporation, the California Secretary of State handles the entity filing. A sole proprietor selling under a name other than their own needs a fictitious business name statement, filed with the county clerk.
What a home operation may and may not do
A home occupation permit is not a blanket permission to run a factory. Cities write their own limits, so read your municipal code rather than a neighboring city's rules. Find the home occupation section in your city's zoning code, and ask the planning department for the ordinance that applies to your address. There is no statewide home occupation permit fee. Each city sets its own fee in its fee schedule.
Typical conditions include a cap on the floor area used for the business, a ban on employees who do not live there, limits on customer visits, and a ban on outdoor storage of materials or finished stock. Some cities also limit deliveries.

If you plan to teach, ask about a conditional use permit before you advertise a class. CDTFA Publication 73, Your California Seller's Permit, explains the permit and filing side. Your city planning department explains how its zoning categories treat home-based work.
Air quality and kiln rules
Some local air districts regulate kilns and other combustion or fume sources. Ask your air district whether a permit or a rule applies to your kiln, and ask your building department about installation and clearances before the kiln is energized. Those answers can limit where a kiln may sit in a home.
Lead and cadmium rules for food-use ware
Pottery that holds food is the part of a home sale most often missed. The FDA sets limits on lead and cadmium that may leach from food-contact ceramics, and a glaze that exceeds them is not legal to sell for food use, whatever the zoning says. Check the current limits on fda.gov before you sell mugs, bowls or plates.
California's Proposition 65 (Health and Safety Code section 25249.6) requires a clear warning before a person is exposed to listed chemicals, including lead and cadmium, above set levels. Decorated and glazed ceramicware has drawn such warnings. Check the current requirements on the Office of Environmental Health Hazard Assessment's Proposition 65 pages before you list a glaze line.
Decorative-only pieces carry a different risk. A pot sold as a planter or a wall piece is not held to the same food-contact limits, but the product description must not suggest that it is safe for food.
Display the permit and show tax on receipts
California requires a seller's permit to be displayed conspicuously at the place it was issued for. For a home studio, that means posting the permit where buyers pick up or pay, and at a market booth, keeping a copy at the booth.
On every sale, show the price and any sales tax as separate lines, and show any shipping charge separately. Keep the invoice showing the buyer's address, because it decides whether tax applies and which rate applies. Check the current CDTFA guidance on invoice content before you print receipts.
Records to keep
CDTFA expects records that support every figure on your return, and the Revenue and Taxation Code requires you to keep them. For a home studio, that means sales receipts, shipping records, and a log of what you fired and when.
Keep purchase invoices for clay, glaze, and tools, because resale and manufacturing exemptions can apply to some inputs. Ask suppliers for a resale certificate, form CDTFA-230, so you are not charged tax on materials you will resell or use in a taxable product. Keep a separate record of any sale you believe is exempt, with the reason written down.
Records must generally be kept for four years. If you sell at a farmers market or a craft fair, the market operator may ask for your permit number before you set up.
Kilns are a fire risk, and a homeowner's policy may not cover business stock or kiln damage. Ask an insurer about commercial property coverage for the kiln and stock, general liability for customer visits, and business income coverage if a fire stops sales.
What happens if you skip it
Selling pottery without a seller's permit is not a paperwork slip. CDTFA can assess tax for the period you sold, add penalties and interest, and estimate your sales if your records are thin. You can ask CDTFA for a review, and if you disagree with the result, appeal to the California Office of Tax Appeals.
A city can also shut the operation down. The first consequence most makers hit is an order to stop selling until the permit and business tax certificate are in place, plus a citation that has to be resolved.
Because you cannot charge a buyer tax after the sale, any tax you failed to collect comes out of your own margin.
