Ventura County NHD Reports & Property Tax Guide

These are the hazard categories that most often drive disclosure answers in Ventura County. Each one is a separate determination on the Natural Hazard Disclosure Statement.

Every property in Ventura County starts from the Proposition 13 base rate of 1% of assessed value, using the purchase price as the base year value and rising by no more than 2% per year. Voter-approved bonds for schools, water, and infrastructure push the typical effective rate in Ventura County to roughly 1.10%, so a bill is usually a little above 1% of what the buyer paid. Ventura County's effective rate is comparatively low, but agricultural, water, and flood control district assessments appear on many parcels. Special assessments are layered on top of the ad valorem rate: Mello-Roos community facilities district taxes in newer subdivisions, 1915 Act bond assessments, and small district charges for lighting, vector control, or sewer service. Those line items are fixed dollar amounts rather than percentages, so they matter most on lower-priced homes. Supplemental tax bills arrive after a sale or new construction to reconcile the new assessed value with the prior owner's.
