California's New 120-Day Pop-Up Business Permit: What AB 1679 Means for Merchants
By Yan Payments
What does AB 1679 actually require?
Governor Newsom signed AB 1679 on September 30, 2026, and starting January 1, 2027, every city and county in California has to offer a new “Temporary Commercial Activation” permit. It lets a retail store or food business move into vacant commercial space and operate there for up to 120 days, without going through the permitting process built for a business signing a five- or ten-year lease. Local governments can run this through their existing permit system or build a new, faster one, but they can’t skip offering it entirely.
Why did lawmakers write this bill?
Assemblymember Mark Gonzalez introduced AB 1679 as part of a package aimed at downtown vacancy, alongside a companion bill, AB 2418, that targets permitting delays more broadly. The logic was straightforward: a lot of commercial space sits empty for months or years partly because the upfront cost and paperwork of a full build-out permit doesn’t pencil out for a business that just wants to try a location, run a seasonal concept, or fill a gap between tenants. A narrower, faster permit path is supposed to make that math work for more operators, and give landlords a way to generate revenue and foot traffic from space that would otherwise sit dark.
What kind of business and space actually qualifies?
The law is built around existing commercial space, not raw land or new construction, and it’s aimed at retail and food concepts, the kind of pop-up shop, gallery, or short-run restaurant that doesn’t need major structural changes to operate. It doesn’t waive health permits, fire code, or ADA access. What it changes is the layer of local business-use permitting that normally assumes a tenant is moving in for years, not months. If a space needs real construction before it’s usable, this program isn’t what gets you there faster.
How is this different from a seasonal booth at a market or craft fair?
Those are a different setup entirely. A booth at a seasonal market usually runs under the event organizer’s own permit plus a short-term seller’s permit from the state, for a weekend or a few weeks, with payments running on cellular data or a hotspot because there’s no fixed infrastructure. AB 1679 is about taking over an actual storefront or restaurant space with a real address and lease, for up to four months, as a standalone operation. If what you’re picturing is a card table at a holiday market, that’s a different thing than what this bill covers.
Will every city roll this out the same way?
Not necessarily, at least not at first. AB 1679 requires cities and counties to offer the permit, but it leaves the implementation details, the application form, the fee, how fast staff turn it around, up to each jurisdiction. A big city with a dedicated planning department may have this running smoothly by spring 2027. A smaller city might take longer to stand up the process, even though the law is already in effect. If you’re planning around this permit, call the local planning or business licensing office directly rather than assuming every city has the same process on day one.
What do you need for payments if you’re moving into a 120-day space?
The upside of a short-term permit is speed, and your payment setup should match that. You don’t want to be negotiating a multi-year merchant services contract for a location you’re leaving in four months. A handheld or countertop terminal like a Clover Flex or Mini (yanpayments.com/hardware) can be set up and running within days, not weeks, and doesn’t require new wiring or a dedicated phone line if the space doesn’t already have one. If the location’s internet isn’t reliable yet, a device with built-in cellular data keeps you from being stuck at checkout on day one. Ask your processor directly whether your agreement locks you into a term longer than the permit itself. A 120-day business has no use for a three-year equipment lease.
A short checklist before you commit to a 120-day space
- Confirm the Temporary Commercial Activation permit, or your city’s version of it, is actually what you’re applying for, not a standard business license built for a long-term tenant
- Check fire, health, and ADA requirements separately. This permit doesn’t waive them
- Ask your landlord whether the space has working internet, and have a cellular backup plan either way
- Match your processing agreement’s term to the length of your occupancy, not the other way around
- Budget for signage, basic fixtures, and a POS setup you can move with you when the 120 days are up
This is general information about a new state law, not legal advice. Check with your city’s planning or business licensing office for how it’s implementing the permit locally, since AB 1679 leaves some of the process up to each jurisdiction.
