ADU Development for Multifamily Properties
ADU1 specializes in helping multifamily property owners increase the income potential of their existing buildings by adding accessory dwelling units. Their focus is on working within permitted zones to help owners understand how many additional units can realistically be developed on their property.
Under current regulations, multifamily properties within permitted zones can develop up to 25% of their existing unit count as attached ADUs, plus up to 2 detached ADUs on the lot. This means, for example, that a 4-unit building could potentially grow to 7 units, or a 16-unit building could expand to 22 units. ADU1 helps property owners navigate these possibilities while also addressing any retrofitting requirements that may apply at the same time.
ADU1 offers a $250 ADU Feasibility Report as an entry point for property owners who want to understand their options. This report covers a land use analysis, a proposed budget, construction feasibility, and an assessment of any adverse site conditions. The goal is to give property owners a clear picture of what to expect before committing to a larger project.
Services Offered by ADU1
ADU1 operates as a design-and-build firm, meaning they handle the full scope of an ADU project from initial planning through to completed construction. Their team includes general contractors, engineers, and attorneys with over 30 years of combined experience.
Their services are structured around three main phases:
- Site Analysis ($250): Assessment of the local ADU ordinance applicable to the property, proposed budget, construction feasibility review, and identification of any site-specific challenges.
- Engineering, Planning & Design: Preparation of all necessary plans, including architectural, structural, and mechanical, electrical, and plumbing (MEP) plans. ADU1 manages the process of getting projects through building and safety departments.
- Construction: Hands-on project management throughout construction, with a dedicated coordinator and accessible point of contact for all project-related questions.
ADU1 also hosts a free weekly ADU Q&A session every Wednesday at 12:30PM, led by their principals Helen and David. This is available to anyone looking to learn more about the ADU development process before committing to a consultation.
Project Management and Client Communication
ADU1 describes their client experience as end-to-end, covering communication, budgeting, staffing, and on-site organization. They emphasize that clients can always reach a live person with full access to project details, and that emails and calls are responded to promptly throughout the project lifecycle.
Their stated priorities include completing projects on time and on budget, with no unexpected surprises. They also handle tenant relationships during construction, which is a relevant consideration for occupied multifamily properties.
For property owners looking to explore whether their multifamily building qualifies for ADU expansion, ADU1's $250 feasibility report provides a structured starting point with input from licensed professionals across construction, engineering, and legal disciplines.
