The ADU Builder
Tap a star to rate
The ADU Builder brings more than ten years of real estate development and construction experience to accessory dwelling units across Los Angeles and Orange County. Based in Long Beach with an actual office at 3646 Long Beach Blvd, the firm holds two active CSLB contractor licenses (1144893 and 1044038), which is uncommon and typically indicates a larger or more established operation. The dual licenses suggest capacity to run multiple projects simultaneously or to handle different scopes of work in parallel without bottlenecking. Operating as a full-service design-build partner means the same team manages design, permitting, and construction from start to finish. This end-to-end ownership of the process reduces the coordination friction that often surfaces when different specialists must align, and it keeps accountability centered on one organization rather than diffused across multiple vendors who may blame each other when timelines slip or quality issues emerge.
The company's service scope spans new detached accessory dwelling units, garage conversions, garage additions, junior ADUs (also called JADUs), tenant improvements, and full or partial remodels. This breadth means they can adapt to a range of property circumstances. If your lot has undeveloped backyard space, they can build a new detached unit. If your property already has a garage you want to repurpose into living space, they know the conversion process inside out. If you are working with a small lot where local zoning allows only a junior ADU (a smaller, secondary unit), they have that skill set. If you want to combine an ADU with a broader home renovation, they can coordinate the scope. The ADU Builder explicitly identifies Long Beach and Orange County as their primary service area, though their portfolio includes completed projects in Eagle Rock and West Hollywood, demonstrating reach into adjacent Los Angeles neighborhoods with comparably complex permitting environments.
The firm structures their process in four clear phases. First, a feasibility assessment determines what is actually buildable on your property and what the local code allows. This matters far more than it might seem: local ADU restrictions in Los Angeles vary by city and even by neighborhood, and sites that look promising can hit unexpected regulatory walls. Second comes design development, where your needs and the site constraints shape the actual unit plans. Third is the planning and permitting phase, where they navigate local approval processes, handle plan checks with municipalities, and work through inspection cycles. Fourth is build execution, the actual construction. This structure gives homeowners visibility into progress and prevents the nasty surprise of discovering mid-project that permits have hit a snag or that a design assumption was invalid.
The firm's completed projects demonstrate genuine range. A Long Beach garage conversion created a 1-bedroom, 1-bathroom unit from an existing structure, which typically costs less and finishes faster than building new because you are not starting from bare land. An Eagle Rock project built a new detached ADU to house grandparents, addressing a common driver for ADU development: multigenerational living or aging in place within a family's own home. A West Hollywood hillside project resulted in a 3-bedroom, 3-bathroom detached unit, which shows the firm can navigate challenging site conditions, steep terrain, and neighborhoods where neighborhood standards and permitting scrutiny are higher than in typical suburban areas. These are identifiable, actual places with specific project details, not generic before-and-after photos from some contractor's stock library.
Client testimonials consistently name Brady as a primary point of contact, alongside team members Jose and Louis. This level of name recognition and specific attribution suggests stable team continuity and a culture where communication flows through named individuals rather than rotating account managers or a phone tree. Clients praise responsiveness, quality of work, and excellent communication throughout their projects. These are the markers of a firm that treats each job as an individual relationship, where your concerns get heard by people who know your project, rather than a high-volume shop where you are the next case number in a queue. The fact that specific team members are cited by name across multiple client reviews indicates they have worked on many projects across years, not just recently.
The ADU Builder does not publish pricing on their public website, which is the norm for construction services where costs swing based on property specifics, local requirements, customization, and market conditions. They reference flexible financing options and offer a "Cost & Budget" resource on their site, suggesting genuine openness to discussing payment structures and possible financing partnerships with homeowners. To get a price, you contact them at (562) 414-6494 or info@theadubuilder.com with details about your property, and they scope out an estimate. Their geographic focus (Long Beach and Orange County), a decade-plus in the market, and two active contractor licenses suggest they have built efficient processes and local relationships that likely keep timelines and costs competitive. Deep familiarity with a single region's permitting and labor market gives any builder an advantage over generalists who move from market to market.
The ADU Builder stands apart from competitors on several fronts. They are not a design-only firm or a permitting consultant dabbling in ADU work; they are actual builders who own every phase and carry all the liability. Dual contractor licenses are unusual enough that you will encounter most competitors with one. Their portfolio spans multiple project types and neighborhoods, showing flexibility rather than a single narrow playbook. Named team members with clear client relationships signal stability and accountability. Long Beach and Orange County are their home market, which means they have real familiarity with the specific permitting quirks of each city and the local labor market, unlike firms that parachute in from outside the region for each project.
If your property is in Long Beach, Orange County, or nearby areas where The ADU Builder has demonstrated expertise, and if you value working with a single firm that owns design through final walkthrough, this is a natural first contact. The deep ADU specialization, dual contractor credentials, completed project range, and client feedback suggest a mature, stable operation ready to navigate whatever complications your property throws at them.
