When evaluating your site, think about population density and how your ADU fits into the fabric of the community, offering social benefits and potentially providing rental income.

During the review, consider the social benefits your ADU could bring to the community, fostering a sense of unity and support, much like the principles of Native American living.

Local Zoning and Building Codes:

Before starting your ADU, explore the zoning laws in your area, which govern aspects like size, setbacks, and land use.

Architectural Design and Aesthetics:

The design of your ADU affects its functionality and marketability. Consider factors like layout and size, thinking about long-term use. A well-designed ADU can increase its value.

Los Gatos values architectural charm, so adhere to the town's design guidelines. Ensure your ADU complements the existing landscape by working with a local architect.
