Sonoma, CA Property Maintenance: Property Blight (2026)

Property blight in unincorporated Sonoma County is handled by the Code Enforcement Division of Permit Sonoma, which investigates complaints involving 'junk and debris accumulation,' housing code violations, abandoned vehicles on private property, and health and safety issues. There is no single 'blight' ordinance with a fixed grass height or item list published on the County's enforcement pages; instead, conditions are addressed as public nuisances and code violations through the administrative process in Chapter 1 of the Sonoma County Code. Code Enforcement states its goal is to 'work collaboratively with property owners to obtain voluntary compliance whenever possible,' prioritizing immediately hazardous fire, life-safety, or health violations. After a complaint, an investigator documents the condition and issues a notice and order to abate; appeals of a notice and order are heard by a hearing officer under Section 1-7.3 of the County Code. Property owners are typically required to abate the violation within 30 days. Where a violation can be legalized through permits, penalties may run five to ten times the base permit fee; for unlawful uses, a daily civil penalty between $5 and $500 per day may be assessed under Section 1-7.1. Complaints are submitted through SoCo Connect, by phone at (707) 565-1992, or by email. This applies only to the unincorporated county; incorporated cities enforce their own municipal codes.
