The Challenge
The homeowners in Burlingame’s Easton Addition neighborhood wanted to create a dedicated space for an aging parent to live independently while remaining close to family. Their property had a spacious backyard, but maximizing the available square footage while preserving outdoor space was critical. Additionally, Burlingame’s architectural character leans heavily on traditional styles, and the homeowners wanted to ensure the ADU blended seamlessly with their existing home. Navigating the city’s permitting process was another challenge, as Burlingame has strict requirements for setbacks, height restrictions, and design approvals, particularly in established neighborhoods like Easton Addition.
Our Approach
Oria Builders began by scheduling a design consultation to understand the family’s functional needs and aesthetic preferences. We proposed a 500-square-foot detached ADU with a single bedroom, full bathroom, kitchenette, and an open living area. To align with Burlingame’s traditional aesthetic, we incorporated exterior elements like board-and-batten siding, a gable roof, and double-hung windows. During the permitting process, our team worked closely with Burlingame’s planning department to ensure the design met all local requirements, including setbacks, maximum height restrictions, and green building codes. We also provided detailed 3D renderings, which helped the homeowners visualize the final outcome and make informed decisions about finishes and materials.
Build Process
The construction phase began with clearing the backyard and grading the site to ensure proper drainage, a critical step given Burlingame’s occasional heavy rains. Our team poured a reinforced concrete foundation and framed the structure using high-quality timber to ensure long-term durability. We coordinated closely with local inspectors, scheduling timely inspections to keep the project on track. Inside, we installed energy-efficient insulation and double-paned windows to meet California’s Title 24 energy standards. Custom cabinetry and quartz countertops were chosen for the kitchenette, while luxury vinyl plank flooring provided a durable yet stylish finish. The exterior was painted in a soft gray with white trim, perfectly complementing the main home. Throughout the process, we maintained clear communication with the homeowners, providing weekly updates and walkthroughs to ensure every detail met their expectations.
