Rohnert Park FAQ
Who has to comply with Chapter 13A?
Every owner and occupant of an improved or unimproved parcel in unincorporated Sonoma County, regardless of whether structures are present.
What is the required defensible space?
A 100-foot radius around each structure (or to the property line) plus 10 feet from roads and driveways must be maintained free of hazardous vegetation and combustible material.
What happens if I ignore the abatement notice?
The County may enter and abate the hazard at the owner's expense. Unpaid fees, abatement costs, and penalties become a lien on the property.
Sonoma FAQ
What triggers a weed-abatement notice?
Annual SVFRA inspections check for grass > 4 inches, dead or dying vegetation, ladder fuels within 100 ft of structures, accumulated leaves/needles, and combustible waste. Any of these may generate a notice with a 30-day cure period under SMC § 14.10.045.
If SVFRA mows my lot, can the city put a lien on my house?
Yes. Under Government Code §§ 38773.1-38773.5 and SMC § 14.10.045, unpaid abatement costs become a special assessment that is recorded as a lien against the parcel and collected on the property tax roll.
