Property-specific ADU planning
Santa Clara County · California
ADU planning for your Santa Clara property
Review available property information, identify what is still missing, and frame the local questions that must be confirmed before design, budgeting, permitting, or construction decisions.
Local authority and planning resources
Use the Property Information Map (MAP) to confirm jurisdiction, then Permit Assistant (POP). The Pre-Approved ADU Plans Program is a plan-set path, not site-specific approval: check PDFs 84561/84559, constraints, and submittals. If not ministerial, review Chapter 18.76 and confirm the City path; do not assume an outcome. Site-specific work needs the City application, plans, existing conditions, and supporting documents.

How do MAP and POP help?
MAP confirms jurisdiction; POP identifies the current path. They are orientation tools, not approval.
Pre-approved or site-specific?
The program covers a City-reviewed plan set; each property still needs site-specific confirmation and submittals.
What if not ministerial?
Review Chapter 18.76 and ask the City which path and materials apply. This guide predicts no outcome.

A useful first review
Separate what is available from what still needs verification.
01
Confirm the property
Start with a complete address and review the available parcel, building, and map context.
02
Identify the unknowns
Keep missing setbacks, easements, utilities, access, hazards, and local requirements visible.
03
Choose the next review
Use the preliminary result to prepare a focused conversation with the required professionals and agencies.

Compare the scope before choosing a solution.
These pages explain the questions each project type introduces. They do not assert that a particular scope is permitted or suitable for your address.
