Introduction
What Are ADUs?
Accessory Dwelling Units (ADUs) are small, self-contained residential units built on the same lot as a primary home. They are also known as granny flats, in-law suites, or backyard cottages. ADUs typically include a kitchen, bathroom, living area, and a separate entrance. They can be attached to the main house, built above a garage, or constructed as a detached structure.
ADUs offer a flexible housing option, providing space for extended family, rental income, or downsizing opportunities. Many cities encourage ADUs to address housing shortages and increase density without altering neighborhood character. Their size and design are often regulated by local zoning and building codes.
Key Benefits & Eligibility
1. Who Can Participate?
Owners of single‑family homes with non‑permitted ADUs or junior ADUs—like converted garages, basements, or attics—that existed before 2020.
Duplexes or multifamily properties may be included in future phases, but are currently ineligible .
2. Confidential & Low‑Risk
All consultations are strictly confidential: you don’t need to disclose your address or identity initially.
The program is voluntary and complaint‑based, meaning the city isn’t increasing enforcement—only those who come forward through amnesty will be addressed.
3. Avoid Fines & Ensure Safety
No retroactive code‑enforcement fines or penalties for eligible units.
Units will be inspected and must meet safety standards, improving living conditions for tenants and reducing homeowner liability.
The broader goal is to expand affordable housing in a city where home prices average around $1.4 million and one-bedroom rents are about $2,250.
