The total value of taxable property in unincorporated Santa Cruz County grew nearly 6% to a record high of $64.7 billion in 2025, according to the Santa Cruz County 2025-26 Assessment Roll.
Home sales and new construction in the county helped boost the value of real estate by $3.6 billion for the year. Proposition 13 caps reassessment by the assessor’s office at 2% annually for properties unless they’re sold, but new development and homes selling on the market pushed the growth of property tax up 5.95% from last year.
