Code section: SMC Chapter 9.56Speaker direction at ROW: Prohibited from businesses

Aircraft Noise

Few Restrictions

The City of Sonoma does not regulate aircraft noise. Aircraft operations and noise emissions are exclusively governed by federal law under FAA jurisdiction, and the nearest airport (Sonoma Valley/Schellville) is regulated by Sonoma County's airport land use compatibility framework, not Sonoma Municipal Code Chapter 9.56.

Jurisdiction: Federal (FAA) — not cityPreempting authority: 49 U.S.C. §§ 40103, 47521-47534

Decibel Limits

Some Restrictions

Sonoma Municipal Code § 9.56.040 sets dBA limits measured at the receiving property line, distinguishing constant from intermittent noise. Commercial property limits are 65 dBA intermittent / 55 dBA constant; residential limits are lower and Chapter 9.56 directs that where two limits overlap, the more restrictive one applies.

Commercial intermittent cap: 65 dBACommercial constant cap: 55 dBA

Vehicle Noise

Some Restrictions

On-road motor vehicle noise is regulated by the California Vehicle Code, not Sonoma Municipal Code. CVC § 27150 requires an adequate muffler at all times and § 27151 prohibits exhaust modifications that increase noise above the statutory limits (95 dBA for passenger vehicles under 6,000 lbs GVWR). Sonoma police enforce these state standards.

Primary authority: California Vehicle Code §§ 27150-27151Passenger vehicle dBA limit: 95 dBA (SAE test, <6,000 lbs GVWR)

Under Sonoma Municipal Code § 19.50.110 (adopted by Ordinance 12-2017 on Dec. 4, 2017), new vacation rentals are not allowed in any residential, mixed-use, or commercial zone of the City of Sonoma. The only exception is the adaptive re-use of a historic structure, and only previously licensed rentals (valid business license + TOT registration as of Nov. 3, 1999) may continue as legal non-conforming uses.

Host must sleep on-site: NoManager availability: 24 hours/day, 7 days/week

Primary-Residence-Only Rule

Heavy Restrictions

Sonoma Municipal Code § 19.50.110 does not impose a primary-residence requirement on the grandfathered pool of vacation rentals because new applications are flatly prohibited. The 'grandfather' test is whether the property held a valid business license and TOT registration on November 3, 1999 — not whether the owner lives there.

Primary-residence requirement: NoneGrandfather test: Licensed + TOT-registered on Nov. 3, 1999

Extended Home Share

Heavy Restrictions

Few Restrictions

City-required minimum: NoneState minimum: None (Civ. Code §1864 = notice only)

Some Restrictions

Sonoma vacation rentals must accommodate guest parking on-site under the conditions of their original use permit and the City's underlying off-street parking standards (SMC Ch. 19.48); on-street overflow that creates neighborhood impacts is grounds for enforcement.
