Occupancy Limits: Hesperia vs San Bernardino
How do occupancy limits rules compare between Hesperia, CA and San Bernardino, CA?
Hesperia has fewer restrictions than San Bernardino.
Hesperia, CA
San Bernardino County
Hesperia has no STR-specific occupancy cap. Maximum occupancy defaults to the California Building Code (Title 24, Part 2, adopted locally through HMC Title 15 Buildings and Construction) and the California Fire Code: each habitable sleeping room must provide at least 70 square feet for the first occupant plus 50 square feet per additional occupant (CBC § 1208 / CRC R304). The common rule-of-thumb derived from this — two persons per bedroom plus one additional — applies in Hesperia. Non-habitable structures (garages, sheds, RVs, tents, yurts) cannot be rented as overnight sleeping space.

Hesperia FAQ
How many people can stay in my Hesperia Airbnb?
Hesperia has no city-specific cap. Use the CBC default: 70 sq ft for the first occupant plus 50 sq ft per additional occupant in each sleeping room. The common shortcut — two per bedroom plus one — is consistent with that standard for typical 100-150 sq ft bedrooms.
Can I rent my converted garage or an RV on my lot?
No. Garages, RVs, sheds, tents, and yurts are not habitable dwellings under the California Building Code adopted at HMC Title 15. Marketing them as overnight space is a code and zoning violation.
Can I list my ADU on Airbnb?
California law (Gov. Code § 65852.2(a)(6)) allows cities to prohibit rentals of ADUs for periods shorter than 30 days. Verify Hesperia's current ADU ordinance in HMC Title 16 before listing — many California cities have invoked this authority.
San Bernardino FAQ
Can I host a wedding at my San Bernardino STR?
Only with a separate special event permit from the Planning Department. Weddings, receptions, and similar gatherings exceed the standard occupancy cap and are not authorized under a baseline STR permit.
Do my kids count toward the occupancy limit?
Children two and older count the same as adults toward the overnight cap. Infants under two are typically excluded when sleeping in a parent room. The permit counts apply to everyone staying overnight.
