Summary

Solano County requires every permitted vacation house rental to be covered by commercial property insurance for the life of the operating permit. The requirement is short but mandatory: Section 28.75.30(A)(9) makes insurance a standing condition alongside occupancy, parking, and fire-safety rules.

These county ordinances apply to unincorporated areas of Solano County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

9. Insurance. The property shall be covered by commercial property insurance.

Full Breakdown

30(A)(9), titled simply 'Insurance,' states in full that the property shall be covered by commercial property insurance. It is one of fifteen numbered standards inside subsection (A) that every vacation house rental in unincorporated Solano County must satisfy, positioned between the transient occupancy tax and business license condition in subsection (8) and the Good Neighbor Measures in subsection (10). The code does not set a minimum coverage dollar amount or name an acceptable carrier list; it requires only that the insurance be commercial property coverage, distinguishing it from an ordinary homeowner's policy that may exclude short-term rental use.

Resource Management can request proof of this coverage as part of the initial land use permit application and at the five-year renewal cycle set by subsection (A)(14), the same review point used to confirm the transient lodging registration certificate and business license required under subsection (A)(8). 30 is designated part of the county's short-term rental ordinance for enforcement purposes under subsection (A)(15), an operator who lets the required commercial property coverage lapse is out of compliance with the operating permit itself, not merely uninsured; Resource Management treats a lapse the same way it treats a missed occupancy limit or an unposted transient lodging certificate, as grounds for administrative enforcement under Chapter 10.

Violations & Fines

Operating a vacation house rental without the commercial property insurance Section 28.75.30(A)(9) requires is enforced as a short-term rental ordinance violation under Section 10-24(b)(3): $1,500 for a first violation, $3,000 for a second within one year, and $5,000 for a third or later violation, and Resource Management can decline to renew the five-year operating permit until coverage is restored.

Frequently Asked Questions

How much commercial property insurance does Solano County require for a vacation rental?
The code does not set a dollar minimum. Section 28.75.30(A)(9) states only that the property shall be covered by commercial property insurance, leaving the coverage amount to the market and the property's value; Resource Management confirms the policy exists rather than auditing its limits.
Will my regular homeowner's insurance satisfy the Solano County vacation rental requirement?
The ordinance specifically requires commercial property insurance, not a standard homeowner's policy. Many homeowner policies exclude paid transient occupancy, so operators typically need a commercial or short-term-rental-specific endorsement to meet Section 28.75.30(A)(9) and avoid a coverage gap the county would treat as noncompliant.
When does the county check that my rental is insured?
Resource Management can request proof of commercial property insurance when the initial land use permit application is filed and again at the five-year renewal required under Section 28.75.30(A)(14), the same cycle used to confirm the transient lodging registration and business license.
