Solano County, CA Short-Term Rentals: Noise Rules (2026)

Solano County does not run its short-term rental noise control as a stand-alone STR noise ordinance with its own decibel table; instead it folds noise into the Vacation House Rental program and the general County noise framework. As part of the VHR application packet, the County requires a Good Neighbor flyer and a Statement of Rules and Regulations, which set guest-conduct expectations - including not creating disturbances that adversely affect neighbors - and the County maintains a Good Neighbor Policy through Planning. These house-rule documents are conditions of the operating permit, so a pattern of verified noise disturbances can support permit suspension or revocation. The County's VHR FAQ includes a dedicated process for how complaints are handled and what fines apply for VHR violations, which is the County's primary noise-enforcement pathway for rentals. Underlying all of this, the general Solano County Code noise standards apply to the property like any other land use. Operators are responsible for their guests' conduct, so the practical noise obligation is to give guests the County-required house rules, keep gatherings from disturbing neighbors, and respond to complaints promptly. We did not find a separately published STR-specific quiet-hours clock in the County's primary materials reviewed here, so none is asserted.
