San Mateo County's property assessment roll increased for the 2019-20 fiscal year, the ninth consecutive year of upward movement.
From Jan. 1, 2018, to Jan. 1, 2019, it increased to a record high of over $238.4 billion in assessed value -- up $15.9 billion, or 7.1%, year-over-year, County Assessor Mark Church said in a press release. The property assessment roll is the assessed value of all properties as of January 1 each year, and reflects changes in ownership, new construction, value declines, and value restorations from the previous January 1, according to the press release.
Menlo Park experienced the highest growth in assessed value, according to the county.
"While there was some softening in the residential market, record growth in commercial and mixed-use development helped push the total roll value to this new high," Church said. "With the lowest annual unemployment rate in the state at 2.2% for 2018 and continued growth of the labor force, San Mateo County's local economy remains one of the strongest in the nation."
Within The Almanac's coverage area, property assessment values rose 10.5% in Menlo Park (down from 11.06% in 2018); 6.62% in Atherton (down from 7.06% in 2018); 5.78% in Portola Valley (up from 5.59% in 2018); and 5.29% in Woodside (up from 4.86% in 2018), according to the press release.
