Fontana Short Term Rental Regulation: A Guide For Airbnb Hosts

Do you own a place in Fontana and you're weighing whether to put it on Airbnb or Vrbo? Well, the good news is that nothing in the city's own code bans that outright, so you're not staring down a wall the way an owner in Santa Monica or Los Angeles might be. Fontana sits in San Bernardino County, in the Inland Empire east of Los Angeles, and the honest picture here is messier than a clean yes, because the city has never written its own short-term rental ordinance the way its mountain and desert neighbors have.

That gap matters, because a lot of what shows up in a search about Fontana STR rules is flatly wrong. You'll see claims that San Bernardino County's short-term rental permit program covers the city, with a specific application fee and an inspection process attached. It doesn't, and the county says so itself: its permit requirement applies only to unincorporated desert and mountain areas, not to an incorporated city sitting in the valley. What the code contains instead is narrower and stranger than that story: a specific ban on renting duplexes built under the state's two-unit lot-split law short-term, a business license requirement that applies to any business run from a Fontana address, and an 8% hotel tax that predates Airbnb by decades.

So let's walk through what that means for you in 2026: what the zoning code does and doesn't say, what licensing and paperwork you're on the hook for, the tax layers that apply, how seriously the city polices any of it, and who to call when a question doesn't have a clean answer. Every figure below comes from Fontana's own municipal documents or the state's, checked in July 2026. Once you know where you stand, run the property through BNBCalc first, because the numbers matter more here than in a city with a bright line either way.

Starting a Short Term Rental Business in Fontana

Running the numbers only tells you something once you know whether you're even allowed to operate, so start with what the zoning code says. Fontana's Zoning and Development Code defines "hotel" and "motel" as commercial establishments with six or more guest rooms, which means an ordinary single-family home never trips that definition no matter how many nights it's booked. The zoning code doesn't have a "short-term rental" use category sitting alongside single-family and multi-family housing at all, and that absence is the whole story for most hosts: your house isn't licensed as an STR, but it isn't zoned against one either.

The one place the code does say "no" in plain language is narrow and specific. Two-unit projects, the second homes built under the state's urban lot-split law (commonly called SB 9), come with a deed restriction attached: "No STRs. No dwelling unit on the lot may be rented for a period of less than 30 days." Make sure you check your property against that before anything else, because if it's one of those splits, that's a hard stop, not a gray area.

A separate, narrow carve-out runs the other way. Fontana's Form-Based Code, which covers the downtown and Sierra Avenue corridor districts rather than the whole city, permits a genuine Bed and Breakfast use. It's capped at six guest rooms, run by an owner who lives on site, requires a Conditional Use Permit, and caps stays between 18 hours and 72 hours at a time, a real legal path to short-stay lodging, though a small and geographically boxed-in one.

Outside those two carve-outs, an ordinary house anywhere else in Fontana sits in the same gray area every unregulated market does, not explicitly permitted and not explicitly banned, running on whatever general rules already apply to houses and to businesses. That's where the business license comes in, because it's the one piece of paper the city asks every operator for.

Short Term Rental Licensing Requirement in Fontana

That business license is the closest thing Fontana has to a short-term rental license, so treat it as mandatory rather than optional. City code requires "any person conducting or purporting to conduct any business, profession, trade or occupation, either directly or indirectly within the City" to file a business license application and pay the tax that comes with it, and the city's own FAQ is explicit that renting out a room or a house counts. The same page confirms licenses can be issued to a business run from a residence, "however, there are restrictions," and it recommends contacting the Planning Division before you start.

Do check with Planning before you assume a home-based rental clears review automatically. I couldn't find an official source spelling out whether short-term lodging is specifically named among the prohibited home occupation uses under Article II, Division 19 of the zoning code, so treat that piece as unconfirmed rather than settled, and get it in writing from the Planning Division before you list anything.

Once issued, the license runs 12 months from the application date, with renewal notices mailed roughly 30 days before expiration; miss the deadline and the penalty climbs 20% per month up to 100% of the tax owed. The fee itself is gross-receipts based: the city's Tax Rate Schedule charges retail-type businesses $50 flat under $50,000 in gross receipts, then $50 plus 25 cents per $1,000 above that, though the page doesn't specify which schedule a short-term rental falls under, so confirm the right one when you apply rather than guessing.

Required Documents for Fontana Short Term Rentals

Since there's no dedicated STR application to fill out, the paperwork trail still runs through the ordinary business license process instead. The city's own Business License Application Instructions walk through what the form asks for. Expect to give your business name and physical location, a description of what the business does, and your ownership type (sole proprietor, partnership, or corporation), along with the matching state and federal ID numbers. None of it is written with Airbnb in mind, so be prepared to describe a short-term rental in plain language on a form built for retail shops and contractors.

Beyond the license application itself, keep a few things ready before you list a property. Don't forget to get your Planning Division home occupation review in writing if you're operating from a residence, since a verbal go-ahead won't help you later. Register for the transient occupancy tax with the city once you cross whatever threshold applies to your situation, a step covered in the next section. And even though Fontana doesn't mandate it on paper, carry liability insurance that covers short-term guests, because a standard homeowner's policy typically excludes paying-guest stays, and that's not a gap you want to discover after something's already gone wrong.

Fontana Short Term Rental Taxes

Assuming you get through the license application and are able to start hosting, there's still tax to sort out, and it comes in two separate pieces that don't talk to each other. The first is the business license tax already covered above, a flat charge on the business itself. The second is the Transient Occupancy Tax, and Fontana's own archived budget documents put it at 8%, describing it as a charge "levied on room rentals at motels and hotels." That 8% figure comes from the city's own FY 2016-17 budget narrative, and I searched for any ballot measure or ordinance since that might have moved it and found none, so treat 8% as the standing rate pending direct confirmation with Finance rather than a number freshly restated this year.

Here's the part that catches new hosts off guard: Airbnb does not automatically collect or remit any occupancy tax for Fontana listings. Its own California tax help page lists San Bernardino County's unincorporated areas at a 7% rate that Airbnb collects on the platform's behalf, but Fontana itself doesn't appear anywhere on that list. That means the tax is on you to register, collect from guests, and remit, not something the platform quietly handles in the background the way it does in dozens of other California cities. Keep in mind, too, that the city's Municipal Code contains its own Article VII specifically titled Transient Occupancy Tax, and while I could confirm that article exists and read the 8% figure from the city's budget materials, I could not load the ordinance text itself to see exactly how it defines "hotel" for tax purposes, so confirm directly with the Business License Division whether a private-home rental is billed the same way a motel room is.

Rental income itself is ordinary taxable income at both the federal and California state level, same as any other rental. If you're weighing whether Fontana's numbers pencil out against a market with a clearer tax picture, BNBCalc Markets is the faster way to check that than working it out by hand.

Fontana-wide Short Term Rental Rules

Paying the right tax assumes you already know which rules govern your specific address, and that's exactly where most of the bad information about Fontana comes from. San Bernardino County runs its own short-term rental permit program, complete with an application fee and an inspection, but it applies only to unincorporated desert and mountain regions of the county, the Big Bear and Joshua Tree side of San Bernardino, not to an incorporated city sitting down in the valley. Fontana residents who read that program's rules and assume they apply are checking the wrong document entirely.

What applies instead is a mix of the two narrow zoning carve-outs from earlier: the outright ban on short-term rental of two-unit SB 9 projects, and the Bed and Breakfast use permitted only within the Form-Based Code district downtown, capped at six rooms with an owner living on site. Everywhere else, general nuisance rules still apply the way they would to any residence, and complaints about noise or parking route through the city's Code Compliance Unit rather than through any STR-specific office, since one doesn't exist.

Above the city, California's statewide short-term rental framework leaves regulatory authority almost entirely with individual cities and counties rather than setting one statewide rulebook, which is exactly why Fontana's silence on the subject is legal rather than an oversight waiting to be closed. The one real state-level development worth watching is Senate Bill 346, the Short-Term Rental Facilitator Act of 2025, approved by the Governor on October 13, 2025. It lets a city or county require Airbnb, Vrbo, and similar platforms to hand over listing addresses and license numbers to help enforce occupancy tax collection, but only where that local agency adopts its own ordinance opting in. I found no evidence Fontana has done so, which lines up with everything else here: the tools to regulate this more tightly exist, the city just hasn't picked them up yet.

Does Fontana strictly enforce STR rules?

That "hasn't picked them up yet" pattern carries straight through to enforcement, because there's very little of it to describe. Unlike Los Angeles or Palm Springs, Fontana has no dedicated short-term rental enforcement unit, no listing-monitoring contractor, and no published citation log for STR violations, because there's no STR-specific ordinance to enforce in the first place. What exists is the general Code Compliance Unit, which handles noise, parking, and property-maintenance complaints for every address in the city, STR or not, reachable through Fontana311.org or by dialing 311 inside city limits.

Don't read that absence as zero risk, though, and be aware that the business license penalty schedule is real and automatic: miss a renewal and the 20%-per-month late fee starts stacking on its own, no inspector required to trigger it. And because SB 346 hasn't been adopted locally as far as I could confirm, platforms aren't yet being compelled to hand your address to the city, but that's a switch the city could flip with one ordinance, not a structural protection. Don't treat Fontana's light touch today as a promise about how things stay in 2027.

How to Start a Short Term Rental Business in Fontana

Given how thin the dedicated rulebook is, the order you do things in matters more than it would in a city with one clean checklist to follow.

1. Check what your property is. Confirm it isn't a two-unit project built under the state's lot-split law, since those carry an explicit short-term rental ban. If you're inside the downtown Form-Based Code district and want to run a small owner-occupied inn, the Bed and Breakfast Conditional Use Permit path is worth a serious look instead of trying to force an ordinary Airbnb listing.
2. Contact Planning before you apply for anything. Get written confirmation on your home occupation status, since a verbal assumption won't hold up later.
3. File the business license application with the Business License Division at City Hall, describing the rental honestly on a form built for retail and trade businesses.
4. Register for the transient occupancy tax with the Finance/Business License office rather than assuming Airbnb is handling it, because for Fontana specifically, it isn't.
5. Line up liability insurance that covers paying guests, beyond a standard homeowner's policy.
6. Set up your own tax collection and remittance process, since the platform won't do it for you here the way it does in most nearby cities.
7. Keep an eye on the city's agendas for any move toward a dedicated STR ordinance or an SB 346 opt-in, because either one would change this checklist meaningfully.

What do Airbnb hosts in Fontana on Reddit and Bigger Pockets think about local regulations?

Given how little there is to enforce, it isn't surprising that Fontana barely comes up in host forums at all, which tells its own story. Reddit blocks the kind of automated access this research would need, so nothing below claims to summarize a Reddit thread; what follows is an editorial read of the broader pattern rather than a survey. On BiggerPockets and similar investor communities, Fontana gets discussed as an Inland Empire logistics and warehousing market, a place people buy rental property because of job growth near the ports and distribution centers, not because it has a short-term rental scene worth debating. Compare that with Big Bear Lake or Joshua Tree, both an hour or two away in the same county, where entire threads exist solely to argue over permit caps and inspection timelines.

That silence is the most honest signal available. A city doesn't generate host forum arguments about occupancy limits and code enforcement raids when it hasn't written the rules that would trigger them. If you're weighing Fontana against a market that has built out a short-term rental system worth arguing about, San Joaquin County's guide and Stanislaus County's guide both cover similar Central Valley logistics-driven markets with a clearer regulatory paper trail to follow. Fontana's version of that paper trail is thinner, and for now, that's the honest state of things.

Frequently Asked Questions

Can you legally run an Airbnb in Fontana in 2026?

Yes, in the sense that nothing in Fontana's zoning code bans an ordinary house from being rented short-term. There's no dedicated short-term rental ordinance, permit, or registration system the way many California vacation destinations have. Hosts still need the standard business license every business in the city requires, and the transient occupancy tax applies. The one explicit ban targets duplexes built under the state's two-unit lot-split law, which cannot be rented for less than 30 days under any circumstances.

Does Fontana require a short-term rental permit or license?

Not a dedicated one. Fontana has never written a short-term rental permit or registration ordinance, unlike San Bernardino County's own program for its mountain and desert communities. What every operator does need is the city's standard business license, the same one any business in Fontana files for, plus Planning Division sign-off if the rental runs from a residence. Contact the Business License Division before listing a property to confirm your specific situation.

What is the transient occupancy tax rate in Fontana?

The city's own budget documents state the Transient Occupancy Tax rate at 8% of room rental charges. That figure comes from Fontana's archived budget materials rather than a same-year restatement, and no ballot measure or ordinance change has surfaced since. Unlike many California cities, Airbnb does not automatically collect or remit this tax for Fontana listings, so hosts need to register directly with the city's Finance or Business License office and handle collection themselves.

Is San Bernardino County's short-term rental permit program relevant to Fontana hosts?

No. The county's short-term rental permit program applies only to unincorporated desert and mountain regions of San Bernardino County, the areas around Big Bear and Joshua Tree. Fontana is an incorporated city in the county's valley region, which places it outside that program's scope entirely, regardless of how often search results suggest otherwise. Fontana hosts deal with the city's own business license and tax rules, not the county's STR permit process.

Can a duplex or ADU in Fontana be used as a short-term rental?

Not if it was built as a two-unit project under the state's urban lot-split law, commonly known as SB 9. Fontana's zoning code attaches a specific deed restriction to those units barring any rental under 30 days. For an ordinary accessory dwelling unit built outside that specific program, no comparable citywide short-term rental restriction turned up in the accessible code, though confirming the status of your specific unit with the Planning Department before listing it is the safer move.
