Whether you’re creating a rental home, a private suite for family, or a flexible guest space, Ataman Studio designs units that blend seamlessly with Los Altos architecture and meet the city’s strict building standards.
💡 Detached ADUs remain the top choice for local homeowners — offering privacy, space, and excellent return on investment.
Los Altos properties vary in lot size and zoning, but every ADU design must balance function, aesthetics, and compliance.
