Assessor warns Prop 19 continues to cost county taxable base; remap project on schedule

Assessor Matt Maynard told the Board of Supervisors on April 29 that the 2024 assessment roll — the county’s taxable value base used for property tax calculations — topped $110 billion and that the assessor’s office is advancing a multi‑year parcel remapping project to modernize GIS and parcel boundaries.

Why it matters: Maynard said Proposition 19 (the 2020 change to intergenerational transfers and base‑year portability) has had an ongoing administrative and valuation effect: counties must track base‑year transfers in perpetuity and the law constrains intergenerational exclusions to principal residences in many cases, producing a measurable loss of taxable value.

Key points - Assessment roll and workload: the 2024 assessment roll totaled more than $110 billion; the office processed roughly 13,000 property transfers and valued about 7,000 new construction events during the roll. - Remap project progress: the assessor’s office has redrawn approximately 62,000 parcels of roughly 195,000 total (about 32% complete). Maynard said the remap project is on time and on budget and that the office has implemented an in‑house field application to capture inspection photos and data directly in the field. - Prop 19 impacts and tracking: Maynard said Proposition 19 — which enables limited base‑year value transfers and tightened intergenerational exclusions — has created ongoing tracking obligations. He cited a figure that, through Dec. 31, 2023, Placer had processed more than 2,080 Prop 19 transfers that have removed an estimated $577 million of taxable value from the roll (the assessor said this figure excludes intra‑county transfers and reflects a historical tally).

Budget context and staffing - Revenue and expenses: the assessor’s budget is largely supported by the general fund and by administrative reimbursements tied to mandated assessment work. The office has been implementing the remap project and using vendor support but reported it expects to continue on schedule without supplemental requests. - Staffing: the office reported five vacancies at the time of the presentation and said one vacancy had been filled recently; Maynard signaled the office will continue to recruit to maintain timely roll preparation.

Board discussion and follow‑up Supervisors asked clarifying questions about Prop 19 mechanics, inter‑county base transfers and whether intra‑county transfers were reported to the state tally (Maynard clarified the state data request focuses on inter‑county flows and not intra‑county transfers). Supervisors praised the remap progress and responsiveness to residents’ questions about individual tax bills.
