Verified from official government sources
Bostonia is unincorporated San Diego County, which does NOT require a short-term-rental permit or business license (unlike the City of San Diego's STRO license). Hosts must still register for Transient Occupancy Tax and follow county zoning, noise, and building rules.
Bostonia short-term rentals must obey San Diego County's noise ordinance (SDCC 36.404). In residential zones the one-hour average sound level limit is 50 dBA from 7 a.m. to 10 p.m. and 45 dBA from 10 p.m. to 7 a.m., measured at the property line.
San Diego County Code Sec. 36.404
It is unlawful for any person to cause or allow the creation of any noise that exceeds the one-hour average sound level limits in Table 36.404... For residential zones the limits are 50 dBA from 7 a.m. to 10 p.m. and 45 dBA from 10 p.m. to 7 a.m.
San Diego County charges 8% Transient Occupancy Tax on rent from stays of 30 consecutive days or less in the unincorporated area, including Bostonia. The operator collects it from the guest and remits quarterly to the County Treasurer-Tax Collector.
San Diego County Code Sec. 22.202
"Transient" means any person who exercises occupancy or is entitled to occupancy... for a period of thirty consecutive days or less, counting portions of days as full days.
Unincorporated San Diego County has no short-term-rental-specific parking requirement. Guests must follow general county parking rules and any zoning off-street parking standards for the dwelling; there is no mandated guest-space count for STRs like some cities impose.
Unincorporated San Diego County does not set a specific short-term-rental guest cap. Occupancy is governed by the general building and safety code and zoning for the dwelling, not a dedicated STR occupancy formula like the City of San Diego uses.
Unincorporated San Diego County does not require short-term-rental operators to carry a specific liability insurance amount. Coverage is strongly advised because standard homeowner policies often exclude commercial short-term rental activity.
Unincorporated San Diego County imposes no annual limit on the number of nights a property may be short-term rented. Bostonia hosts may rent year-round, unlike City of San Diego tiers that cap certain listings at a set number of nights per year.
Unincorporated San Diego County STR operators must register with the Treasurer-Tax Collector and obtain a Transient Occupancy Registration Certificate. Under SDCC 22.206, registration is due within 30 days of commencing business and annually each July.
San Diego County Code Sec. 22.206
Within 30 days after commencing business... an operator of a hotel renting occupancy to transients shall register the hotel with the Tax Collector and obtain from the Tax Collector a transient occupancy registration certificate.
San Diego County does not require the host to be present or on-site for short-term rentals in unincorporated areas like Bostonia. Unhosted, whole-home rentals are permitted, subject only to TOT registration and general zoning, building, and noise rules.
Unincorporated San Diego County does not restrict short-term rentals to a host's primary residence. Non-owner-occupied and investor STRs are allowed, unlike the City of San Diego's tiers that reserve some categories for primary residences.
County ordinances apply to unincorporated areas and may supplement Bostonia city rules.
