Innovative ADU Design and Inspiration

We believe that excellent design maximizes both function and style. Our architects draw inspiration from cutting-edge trends and local architecture to create ADUs that feel integrated and inviting. For example, our team can help you design an ADU for maximum value — optimizing every square foot with efficient layouts and high-end finishes. Each ADU is tailored to your property, whether it’s a detached cottage in your backyard or an attached addition to your home. We guide you through choices like Detached vs Attached ADUs, ensuring the design complements your existing home and neighborhood.

Permitting, Compliance and Construction Process

Building an ADU in Hayward requires navigating local and state regulations. Our experts manage the entire permitting process and ensure full code compliance. We handle everything from California’s updated ADU ordinances to local planning guidelines, so you avoid costly delays. Our streamlined Bay Area ADU construction process covers every step, keeping your project on schedule. We also stay current on new housing laws — such as recent SB-9 zoning changes that affect lot splits and ADU development. Where eligible, we can even advise on density bonus incentives to increase unit size. With our guidance, you can relax knowing we’ll secure all necessary permits and approvals for your project.

High-Quality Construction and Sustainable Features

Our skilled tradespeople bring precision and care to every ADU construction. We use durable, high-quality materials and build to the latest industry standards. For example, we can equip your new ADU with energy-efficient windows and smart home wiring, reducing energy costs and improving comfort. Each foundation and wall is built to code, incorporating Bay Area-specific earthquake retrofitting measures for added safety. The result is a modern, resilient ADU that is both beautiful and built to last.
