Estimate ADU Fees and Costs
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, any non-ADU project should use the County’s standard Residential Building Permit Fee Estimate Worksheet rather than this tool 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 questions related to planning and zoning and email firstname.lastname@example.org for questions related to building permits.
