At American New Generation Construction Inc., we design and build custom ADUs that expand your property’s potential. Whether you’re looking for a rental unit, guest house, or in-law suite, our team delivers a turnkey solution from design to final inspection.
As trusted ADU builders in California, American New Generation Construction Inc. helps create high-quality, compliant accessory dwelling units that add value, comfort, and flexibility. Adding an ADU is one of the smartest investments for California homeowners today. From generating rental income to creating space for family, these units offer flexibility, value, and long-term benefits.
Our team specializes in the entire ADU process—planning, permitting, design, and construction—ensuring your project is fully compliant with local regulations. With experience across a wide range of ADU styles, we deliver high-quality builds that fit seamlessly into your property.
Transform your underutilized garage into a fully functional living space. Garage conversions are one of the most cost-effective ways to add an ADU, offering the benefits of an independent rental unit, guest suite, or home office without expanding your property’s footprint. Our team manages every detail, from structural adjustments and insulation to plumbing, electrical, and interior finishing. We ensure your garage-turned-ADU meets California building codes and energy standards, giving you a safe, comfortable, and attractive living space. A well-executed conversion not only provides extra square footage but also increases the overall value of your home.
Backyard ADUs, also called “granny flats” or “casitas,” provide a stand-alone living unit that maximizes unused outdoor space. These builds are ideal for rental income, extended family, or private guest accommodations. Our team helps you design an ADU that blends seamlessly with your existing property while staying within local zoning and setback requirements. From pre-construction planning to final inspection, we handle every stage of the project. With durable construction, modern finishes, and energy-efficient features, a backyard ADU is a smart investment that creates long-term flexibility for your home. Our team handles everything from demolition and layout redesign to plumbing, electrical, and finishing details. Whether you want to update outdated interiors, expand usable space, or completely reimagine your property, we work closely with you to create results that are functional, stylish, and built to last. Every remodel is customized to match your goals and enhance the value of your investment.
Many California cities now offer pre-approved ADU plans to help homeowners save time and reduce costs. Our team guides you through selecting and adapting one of these plans to fit your property and needs. By working with pre-approved designs, you can often shorten the permitting process and streamline construction while still enjoying a high-quality build. We’ll ensure your chosen plan is optimized for space, style, and functionality, and we’ll make any necessary adjustments for utilities, finishes, and site conditions. With our guidance, you can confidently move from planning to building with fewer obstacles.
A comfortable ADU requires more than just walls and a roof—it needs reliable systems. We install complete electrical, plumbing, and HVAC solutions to make your ADU fully functional and compliant with modern standards. From panel upgrades and energy-efficient wiring to water connections and climate control, our licensed professionals handle it all. We coordinate system installations during construction to keep projects on schedule and avoid costly delays. By focusing on safety, efficiency, and performance, we ensure your ADU is not only move-in ready but also comfortable and cost-effective to maintain.
Building an ADU requires strict adherence to city zoning laws, building codes, and permit processes. Our team handles these complex requirements on your behalf, ensuring your project remains compliant from start to finish. We prepare and submit all necessary paperwork, coordinate with local agencies, and schedule inspections so you don’t have to. By managing the permit and zoning process, we help avoid costly setbacks or legal complications. With us, you’ll have peace of mind knowing your ADU meets all regulations and is approved for safe, legal occupancy once construction is complete.
