ADU Construction Services by Edri Construction, Inc. in the Bay Area
An Accessory Dwelling Unit (ADU) is more than a simple home addition — it represents a practical investment that can meaningfully expand a property's utility and value. Edri Construction, Inc. is a San Francisco-based general contractor that specializes in full-service ADU construction throughout the Bay Area. As an experienced ADU builder, they manage projects from initial design through final walkthrough, with a working knowledge of local zoning regulations and permit requirements specific to the region.
Their services cover a broad range of ADU types, including detached ADU builds, garage conversions, attached additions, and custom interior design — making them a versatile option for homeowners exploring accessory dwelling unit construction.
ADU Design and Planning
The process begins with a detailed consultation to understand the homeowner's vision, budget, and property constraints. Edri Construction handles permit applications and documentation, navigating San Francisco's regulatory landscape on behalf of their clients. Feasibility studies are conducted early to identify potential site challenges, and their architects work to maximize usable space within allowable limits while keeping designs compliant and functional.
Garage Conversion Contractor Services
For homeowners looking to make use of an underutilized garage, Edri Construction offers full garage conversion services. As a garage conversion contractor, they manage structural modifications, insulation upgrades, foundation work, and interior finishes to bring the space up to residential code. The goal is to convert what was previously storage into a livable, comfortable unit suitable for rental or personal use.
Detached ADU Builder
Edri Construction also specializes in building stand-alone backyard units — often referred to as backyard cottages or casitas. These detached ADU builds offer occupants greater privacy and allow for more design flexibility. Their team handles all aspects of the construction process, including site preparation, utility trenching, foundation work, and final finishes. Whether the vision is a contemporary studio or a more traditional cottage-style structure, they deliver a turnkey unit.
Attached ADUs and Home Additions
For those who prefer to expand their existing home's footprint, Edri Construction builds attached ADUs that integrate with the current structure. They assess load-bearing capacity and match exterior details — including siding, roofing, and trim — so the addition blends naturally with the original property. This option is commonly chosen for in-law suite builds or multi-generational living arrangements.
Custom Interiors and Smart Space Design
Edri Construction places emphasis on making smaller footprints feel functional and well-appointed. Their interior design approach focuses on intelligent layouts and quality finishes, including full kitchens and well-designed bathrooms. The aim is to ensure every square foot serves a clear purpose, resulting in a space that feels complete rather than compromised.
Granny Flat and In-Law Suite Builder
For families seeking multi-generational living solutions, Edri Construction designs and builds granny flats and in-law suites with accessibility in mind. Features such as wider doorways and stepless entries are incorporated where needed, making these units suitable for aging parents or adult children returning home.
Sustainable and Energy-Efficient Construction
Energy efficiency is a consideration built into their construction process. Edri Construction uses advanced insulation, Energy Star-rated windows, and eco-friendly materials. They also accommodate solar-ready roofing and tankless water heater installations, helping to reduce long-term utility costs and environmental impact.
Project Management and Quality Control
Edri Construction operates as a one-stop shop, coordinating subcontractors and managing project details in-house. This integrated approach is intended to maintain consistent quality and reduce the communication gaps that can arise when work is outsourced. Dedicated project managers keep clients informed throughout the build, from initial planning through completion, with the goal of keeping projects on schedule and within budget.
