In Thousand Oaks, property tax follows California's Proposition 13: about 1% of assessed value plus local voter-approved bonds, for a typical effective rate near 1.1%-1.25%. Newer master-planned tracts can add Mello-Roos (a CFD special tax) on top. This calculator estimates your annual and monthly property tax and shows the effective rate. Verify the exact figure for any parcel with the Ventura County Assessor.
How California property tax works
Proposition 13 caps the base ad valorem rate at 1% of assessed value and limits annual increases in assessed value to about 2%, with reassessment to market value generally on a change of ownership. On top of the 1% base, Thousand Oaks parcels carry voter-approved bond measures and direct assessments, which is why the effective rate usually lands a little above 1%.
Mello-Roos in Thousand Oaks
Most established Thousand Oaks homes don't carry Mello-Roos, though some newer developments (and nearby Newbury Park tracts like Dos Vientos) do. Verify the tract. A Mello-Roos CFD is a separate special tax that funds infrastructure in newer developments and is added to your base bill - it can add hundreds of dollars a month, so always confirm it before writing an offer.
