Custom ADUs and Granny Flats
Custom ADUs are fully tailored to your specific requirements. We work closely with you to design floor plans, materials, and layouts that maximize space usage and comply with Norwalk building codes, considering the city's historical roots dating back to the late 19th century.
Granny flats are a popular form of custom ADU focused on multi-generational living or rental income.

We prioritize efficient floorplans, natural light, and privacy. These projects typically involve new construction in a backyard or unused lot space, often requiring careful site analysis and permits.
Garage-to-ADU Conversions
Garage conversions transform existing structures into livable ADUs. We specialize in garage renovation that includes insulation, plumbing, electrical upgrades, and structural modifications designed to withstand Norwalk's occasional Santa Ana winds.
This option is cost-effective compared to new ADU builds and shortens construction time since the foundation and shell already exist. We assess garages for size, access, and code compliance before converting, and offer a 10-year structural warranty on all completed conversions.
Our team customizes layouts to include kitchens, bathrooms, and bedrooms within the garage footprint. This is ideal for homeowners wanting rental units or extra living spaces in a city where 34.9% of housing units are renter-occupied.

We provide prefab ADU builders and modular home builders solutions using factory-built components. These ADUs offer fast installation and consistent quality, minimizing on-site labor in Norwalk's year-round mild climate with approximately 280 sunny days annually.
Tiny home ADUs, constructed by tiny home builders specializing in ADUs, are compact, often under 400 square feet. They focus on efficient storage and multi-use furniture to maximize limited space.
Prefab and modular ADUs suit those seeking quicker build times and potentially lower costs. We handle site prep and utility connections, coordinating closely with manufacturers to ensure smooth delivery and setup.
