Estimate County ADU Fees
The ADU Fee Estimator tool has been developed to estimate Santa Cruz County fees specifically for ADU projects! Applicants enter information about ADU projects and based on the information provided, the tool estimates County fees, project costs, and cash flow over time.
PLEASE NOTE: This tool does NOT estimate fees for non-County agencies. Also, if a project involves a new home or an addition that is NOT associated with an ADU, applicants should instead use the County’s Residential Building Permit Fee Estimate Worksheet for accurate fee estimates.
QUESTIONS about how to use the Fee Estimator? Please consult our Fee Estimator Instructions for ADU Projects. If you still have questions, Building and Zoning staff is happy to help you understand our fees. Please contact Planning.ZoningInfo@santacruzcounty.us or call (831) 454-2130 for Zoning information and (831) 454-2260 for Building information.
