San Luis Obispo Property Tax Rate

The typical property-tax rate in San Luis Obispo is about 1.1% of assessed value — the 1% Proposition 13 base plus voter-approved debt. That's below the average across these California cities (~1.14%). Mello-Roos and fixed direct assessments, where a parcel has them, are billed on top.

Multiply your assessed value by about 1.1%. Under Proposition 13 your assessed value is generally what you paid when you bought, rising no more than 2% a year — use the calculator above for your own number.

Property tax in San Luis Obispo is about 1.1% of the price you pay, so a buyer's bill scales with the home. A new purchase is taxed on its price — enter yours in the calculator above for the exact figure.

San Luis Obispo spans more than one Tax Rate Area (it has 19). The 1% base is the same everywhere, but each area adds its own voter-approved school, city, and special-district bonds, so two homes in San Luis Obispo can pay slightly different total rates. The figure here is the typical rate across San Luis Obispo's parcels.

The 1.1% shown here is from San Luis Obispo County's 2025-26 tax-rate book — the rate on the bills that came due in December 2025 and April 2026. The bills mailed in October 2026 are for fiscal year 2026-27: the 1% Proposition 13 base never changes, and the voter-approved debt rates on top of it are recalculated by the county each year, after the roll closes on July 1 and before the Board of Supervisors adopts the rates by October 3 (Gov. Code §29100), as bonds are paid down or sold, so the total usually moves by a few hundredths of a percent, not whole points. What does change for most owners is the assessed value: the Board of Equalization set the 2026-27 inflation factor at 2%, so a San Luis Obispo home that did not sell or add construction is assessed 2% higher than last year and its bill rises about 2% if the rate holds. A home bought or built in the past year is taxed on its new base-year value instead, and usually gets a supplemental bill.

San Luis Obispo County bills San Luis Obispo property taxes in two installments: the first is due November 1 (delinquent after December 10) and the second February 1 (delinquent after April 10), with a 10% penalty after each date. These deadlines are set by California state law and are the same countywide. Bills are issued and paid through the San Luis Obispo County Treasurer-Tax Collector, not the city of San Luis Obispo.
