Authored by Assembly Member Phil Ting, Assembly Bill 551 created the Urban Agriculture Incentive Zones (UAIZ) Act which promotes small-scale commercial or noncommercial agricultural use on vacant, unimproved or blighted lands in urban areas. Adopted in 2013, AB 551 allows cities and counties to create UAIZs, offering preferential property tax assessment to owners of eligible urban lots who agree to enter into a contract restricting the property use to small-scale production of agricultural crops and animal husbandry for a period of five years

About Prop 8

Proposition 8 was passed in November 1978 as an amendment to Proposition 13 and implemented as Revenue & Taxation Code Section 51(a)(2). It annually caps the assessed value of property as of the lien date (January 1) at the lesser of its market value or its factored base year value.


Proposition 8 allows a temporary reduction when the market value of property has fallen below its factored base year value as of the January 1 lien date. Once a Prop 8 reduction has been enrolled, the property’s assessment must be reviewed annually to ensure that the lesser of the market value or the factored base year value is enrolled.

The property’s base year value continues to be factored at a maximum two percent per year, setting its maximum assessed value. As the market recovers the market value of a property will increase based on market conditions which are not restricted to a two percent growth. The value enrolled will follow the market growth rate until the market value exceeds the factored base year value and the lower factored base year is enrolled.

Factored base year value: the value established as of the date of acquisition and/or completion of new construction. This value is adjusted each year by an inflation factor. The inflation factor is the lesser of 2% or the California Consumer Price Index (CCPI) rate.

For more information about factored base year value, see Understanding Proposition 13.

Bay Area homes: prices up, sales down from 2015

The median price for single-family homes in the Bay Area jumped last month to a record $750,000, reflecting the region's red-hot demand for housing -- even as short supply drove down the number of homes sold. The new Bay Area high was up 7.1 percent from the year before and surpassed the nine-county region's previous record of $738,500, set in July 2007. In May 2015, the Bay Area median was $700,000.
