Step 1: Understand Los Altos ADU Regulations

Before diving into your ADU project, it’s essential to familiarize yourself with Los Altos' zoning laws and building codes. California state laws encourage ADU construction, but each city has specific rules to follow.

Permit Process

Los Altos requires homeowners to apply for an ADU permit, which involves submitting plans, undergoing reviews, and ensuring compliance with the California Building Standards Code. The city typically expedites ADU permits to encourage development.

Step 2: Plan Your ADU Design Thoughtfully

Design is a critical aspect of creating an ADU that complements your property and meets your goals. Here are some tips for effective ADU design planning:

Define the Purpose

Work with Professionals

Hiring an architect or designer familiar with Los Altos' regulations can ensure your ADU integrates seamlessly with your property while maximizing available space.

Maximize Space and Light

• Use an open floor plan to make smaller ADUs feel spacious.
• Incorporate large windows and skylights for natural light.

Review Past Projects

Request to see examples of previous ADU projects. This will give you insight into their quality of work and design style.

Ask for References

Contact past clients to learn about their experience with the contractor, including communication, timeliness, and problem-solving abilities.
