Building an ADU in Los Altos, Simplified

Site Evaluation & ADU Feasibility

In Los Altos, ADU feasibility is often shaped by lot size, setbacks, and access requirements. Early planning focuses on how to position the unit within these constraints while maximizing usable space within lot coverage limits and rear and side yard requirements common in Los Altos properties.

Planning, Zoning & Permit Coordination​

Each project must meet California ADU standards along with local requirements related to height limits, parking, and utility connections, including sewer, water, and electrical tie-ins. We coordinate engineering and plan submissions while managing communication with the city and inspection timelines to keep approvals moving forward.

Efficient Design & Space Optimization

ADUs in Los Altos often require working within tight footprints while meeting setback and height limits. Design decisions focus on how to make the most of available square footage within the constraints of the existing home footprint; bringing in natural light, improving circulation, and integrating storage without sacrificing comfort. The goal is a layout that feels open, practical, and easy to live in day to day.

Construction & Final ADU Delivery

ADU construction requires careful coordination between inspections, utilities, and city requirements throughout the build, including inspection sequencing and utility coordination. We manage scheduling and sequencing to keep everything aligned with approved plans while minimizing delays. The finished space integrates cleanly with your property and is ready for immediate use, whether for rental income, multi-generational living, or private guest accommodations.
