Building an ADU is a significant investment, and we understand the importance of choosing a contractor you can trust. Here’s why homeowners throughout Penryn turn to us for their ADU construction needs:
Expert Design & Planning: We help navigate zoning regulations, permits, and design options to ensure your ADU meets all local requirements and your personal preferences.

We offer full-service ADU construction solutions, handling everything from concept to completion. Our expertise includes:
Every successful ADU project starts with a well-thought-out design. We work with you to create a functional and aesthetically appealing layout that aligns with your goals. Whether you want a compact studio or a spacious two-bedroom unit, our designers will ensure your ADU meets your needs while adhering to local zoning and building codes.
Looking to transform your existing garage into a livable space? We specialize in garage conversions, turning underutilized areas into beautiful, self-sufficient living spaces. Our team ensures proper insulation, plumbing, electrical, and structural modifications to make your new ADU both comfortable and compliant with city regulations.
Whether you need a detached unit for added privacy or an attached ADU for easy access to the main house, we provide solutions tailored to your property layout and lifestyle needs. Our detached ADUs are ideal for rental income or extended family members, while attached ADUs seamlessly integrate with your existing home structure.
If you have unused backyard space, a cottage-style ADU can be a perfect addition. These charming units serve as guest houses, home offices, or even short-term rental opportunities. We design and build backyard cottages that blend beautifully with your home’s architecture while maximizing outdoor space.
Creating a comfortable living space for aging parents or extended family members is a growing trend. Our in-law suite ADUs provide independent yet connected living arrangements, complete with private entrances, kitchens, and bathrooms.
Navigating the permitting process can be overwhelming, but we handle it all for you. Penryn has specific ADU regulations regarding setbacks, square footage limits, and occupancy requirements. Our team ensures that your ADU project meets all city and state guidelines, securing necessary permits and approvals so you can focus on the excitement of your new space.
