Noise Rules: Elfin Forest vs San Marcos

Are there special noise rules for Airbnbs in unincorporated San Diego County?

No. There are no STR-specific noise regulations. All properties must comply with the county's general noise ordinance, which sets limits of 50 dBA during the day and 45 dBA at night at the property line.

What should I tell my STR guests about noise?

Inform guests that nighttime quiet hours run from 10 PM to 7 AM and that noise measured at the property line must not exceed 45 dBA during those hours. Provide the county's non-emergency number for neighbor concerns.

Can my neighbor's STR be shut down for repeated noise complaints?

Repeated noise violations could lead to nuisance abatement proceedings, but the county does not currently have a mechanism to revoke an STR permit since no specific STR permit is required in unincorporated areas.
