ADU Construction Services by Edri Construction, Inc. in Walnut Creek
Edri Construction, Inc. is a Bay Area-based general contractor specializing in accessory dwelling unit (ADU) construction. Operating out of Walnut Creek, they offer full-service ADU building, covering everything from initial design and permitting through to final completion. Their work spans a range of ADU types, and they are familiar with the zoning regulations and permit requirements specific to the Bay Area region.
An ADU can serve a variety of purposes — housing a family member, generating rental income, or providing a dedicated workspace. Edri Construction approaches each project with that flexibility in mind, working with homeowners to identify the right solution for their property and goals.
Types of ADU Projects They Handle
Garage Conversions: Edri Construction works with homeowners looking to convert an existing garage into a livable space. As a garage conversion contractor, they manage structural modifications, insulation upgrades, foundation work, and interior finishes to bring the space up to residential code. This is a practical option for those who want to add living space without building from the ground up.
Detached ADU Construction: As a detached ADU builder, Edri Construction handles the full build of standalone backyard units. This includes site preparation, utility trenching, foundation work, and all finishing details. Detached units offer more privacy and design flexibility, whether the goal is a compact studio or a more traditional backyard cottage.
Attached ADUs and Home Additions: For homeowners who prefer to expand their existing structure, Edri Construction builds attached ADUs that integrate with the current home. They assess load-bearing capacity and match exterior details — siding, roofing, and trim — so the addition fits cohesively with the original property.
In-Law Suites and Multi-Generational Living: Edri Construction also designs and builds in-law suites and granny flats tailored for multi-generational households. These spaces can be designed with accessibility in mind, incorporating features like wider doorways and stepless entries to accommodate aging family members or those with mobility considerations.
Junior ADUs (JADUs): For properties where a full ADU may not be feasible, smaller JADU configurations within the existing home footprint may be an option worth exploring with their team.
Design, Planning, and Project Management
Edri Construction's process begins with understanding the homeowner's vision, budget, and site conditions. They conduct feasibility studies early in the process to identify potential challenges before construction begins. Their team handles permit applications and navigates local regulatory requirements on behalf of the client.
Interior design is also part of their scope. They focus on making smaller footprints functional through thoughtful layouts and quality finishes, including full kitchens and bathrooms. The goal is to create a space that feels complete rather than like a secondary afterthought.
On the sustainability side, Edri Construction incorporates energy-efficient building practices into their ADU projects. This includes advanced insulation, energy-rated windows, and options for solar-ready roofing or tankless water heaters — features that can reduce long-term utility costs.
Project management is handled in-house, with dedicated managers coordinating subcontractors and keeping clients informed throughout the build. By managing the process internally, they aim to maintain consistent quality control and keep projects on schedule and within budget.
