San Bernardino County Caps STR Permits: Two Per Host, $1,000-a-Day Fines

San Bernardino County has drawn a hard line for short-term rental hosts: run without a permit and you owe $1,000 per violation per day. That is not a warning letter. That is a fine that compounds every single day until you come into compliance, and the county's Code Enforcement division is the one writing the tickets.

What the County Has Actually Done

Short-term rentals of 30 days or less are legal in unincorporated San Bernardino County, but only in the Mountain and Desert regions. That covers popular markets like Joshua Tree, Morongo Valley, and the unincorporated Big Bear area. If your property sits in the Valley region, or inside an incorporated city like Big Bear Lake, Twentynine Palms, or Yucca Valley, county rules do not apply to you directly. Those cities run their own programs.

For everyone else in the eligible zones, the county requires a Short-Term Residential Rental Permit issued by Code Enforcement. There is no grandfathering your way around it. Every unit needs one, and the permit must be displayed in every advertisement along with the property's maximum occupancy.

The Caps That Will Catch Hosts Off Guard

The rules that will sting the most are the hard caps baked into the ordinance. The county limits any single person to no more than 2 STR permits total. On the parcel side, properties under 2 acres are limited to 1 permit per parcel. Only if your parcel hits 2 acres or more can you hold 2 permits on the same land. And regardless of how big the property is, overnight occupancy is capped at 12 guests.

For hosts who have been quietly running multiple listings under one name, or stacking rentals on a single lot, this is the rule that forces a hard choice. The county is not leaving room for creative workarounds.

What a Permit Actually Costs

Under the fee schedule that took effect July 1, 2025, a new application runs $1,144 total. That breaks down as a $600 application fee, a $285 permit fee, and a $259 surrounding property owner notification fee. Renewal is cheaper if nothing changes: $550 for a straightforward renewal. If you make physical changes to the property, the renewal climbs to $885. Change your property management or occupancy limits and it is $859. Do both and you are back to the full $1,144.

There is one cost-saving move available: install an outdoor noise monitoring device and the county offers a $150 one-time credit. Given the 24/7 complaint hotline the county operates, a noise monitor is not a bad investment on its own terms.

The Inspection and Neighbor Notification Process Is Real

Getting a permit is not just filling out a form. Code Enforcement requires an exterior inspection before a permit is issued. Hosts also complete an interior self-inspection checklist. Neighboring property owners get a 20-day comment period, and there is a 30-day appeal period before the permit is finalized. Plan for this process to take time, especially in busy markets where neighbors may have opinions.

Once you are operating, the county's response requirements are strict. The owner or designated agent must be reachable around the clock, make contact within 30 minutes of a complaint, and be physically present at the property within 1 hour. Failure to respond is not just a fine risk. It can lead to permit revocation.

Taxes on Top of Everything Else

Hosts in unincorporated areas also owe a Transient Occupancy Tax of 7% of gross revenue. On a typical nightly rate, that is a meaningful amount going to the county each night. Platform collection varies depending on your listing site and your agreement with it, so confirm how your platform handles remittance rather than assuming it is covered.

What Hosts Should Do Right Now

• Confirm your property is in an unincorporated Mountain or Desert zone, not the Valley region or an incorporated city.
• Check how many permits you currently hold or plan to hold. The two-permit-per-person cap is absolute.
• Budget for the $1,144 new application fee and the time required for inspection and neighbor notification.
• Set up a 24/7 contact system. The county will call, and the clock starts immediately.
• Make sure every active listing displays your permit number and maximum occupancy. Missing either is a compliance violation.
