Property Taxes in San Diego County
Every property in San Diego 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 San Diego County to roughly 1.13%, so a bill is usually a little above 1% of what the buyer paid. Newer inland subdivisions in Chula Vista, Otay Ranch, San Marcos, and Santaluz frequently carry Mello-Roos special taxes. 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.
