Choose your city

In California, ADU construction is influenced by varying climate conditions and the state's extensive housing stock, which often includes single-family homes with sufficient lot sizes. Coastal areas may require specific considerations for salt spray and humidity, while inland regions necessitate attention to heat and potential fire risks. Our process accounts for these environmental factors to ensure your ADU is built for longevity and comfort.

Navigating California's permitting process is a critical step. While statewide laws have streamlined ADU approvals, local jurisdictions can have specific zoning ordinances and design review requirements, especially in a dense metro like Los Angeles. We guide you through obtaining the necessary permits, working with city planning departments to ensure compliance and a predictable construction schedule. This detail-oriented approach minimizes delays and unexpected costs.
