Accessory dwelling units (ADUs) have become a hot topic in many cities, and Palo Alto is no exception. These versatile living spaces offer homeowners a range of benefits, from additional income to increased property value. In this comprehensive guide, we'll explore everything you need to know about ADUs in Palo Alto, including size restrictions, design tips, and the permitting process. By the end, you'll have all the information you need to consider adding an ADU to your property.
What is an ADU?
An accessory dwelling unit (ADU) is a secondary housing unit on a single-family residential lot. These units can be attached to the main home, detached, or even converted from existing spaces like garages. ADUs are a popular choice for homeowners looking to maximize their property's potential without a significant expansion.
The Benefits of ADUs for Homeowners
Adding an ADU to your property comes with several benefits. Firstly, it provides an opportunity for additional rental income, which can help mitigate the cost of your mortgage. Secondly, ADUs are perfect for multigenerational living, allowing family members to live close by while maintaining their independence. Lastly, an ADU can significantly increase your property value, making it a wise investment for the future.
Size Restrictions and Regulations for ADUs in Palo Alto
Understanding the size restrictions and regulations for ADUs in Palo Alto is crucial. Here’s a detailed breakdown:
Attached ADUs can be up to 900 square feet for a studio or one-bathroom unit, and up to 1,000 square feet for units with more than one bedroom. However, they must not exceed 50% of the primary dwelling's living area.
Detached ADUs follow the same size limits as attached ADUs – 900 square feet for a studio or one-bathroom unit, and 1,000 square feet for larger units.
Junior ADUs are limited to 500 square feet.
Additionally, these units must adhere to various other regulations, such as setbacks, height limits, and parking requirements.

Detached units must maintain a minimum three-foot distance from the primary unit.
