EcoSmart Builders: ADU Contractor and Custom Construction Services
EcoSmart Builders is a licensed construction company based in Southern California, specializing in accessory dwelling units (ADUs), home expansions, and fire rebuilds. With over a decade of experience, they operate as a full-service ADU builder, managing projects from initial design through permitting and final construction.
Their core approach follows a straightforward three-step process:
- Design – Floor plans, elevations, and finish selections are developed to match the homeowner's vision.
- Permit – EcoSmart Builders coordinates with engineers, Title 24 consultants, and city agencies to handle all permitting requirements.
- Build – Licensed, insured, and FSRT-certified crews carry out construction that is safe, clean, and code-compliant.
Cost proposals are structured with CSI breakdowns and clear allowances, so homeowners understand exactly what is included before work begins. Budget tracking and dedicated client communication are maintained throughout every stage of the project.
Accessory Dwelling Unit Services
As an experienced ADU contractor serving Los Angeles County, EcoSmart Builders offers a range of accessory dwelling unit solutions for residential properties. They work with homeowners to evaluate whether an ADU is a practical addition to their property, assist with financing options, and manage the entire design and construction process.
An accessory dwelling unit is an independent residential unit added to an existing single-family property. It includes its own kitchen, bathroom, living area, and entrance. ADUs can serve as rental housing, guest accommodations, home offices, or additional living space for family members.
EcoSmart Builders works with several types of ADUs:
- Detached ADU – A stand-alone backyard cottage or separate structure built independently from the primary home, or constructed over an existing detached garage.
- Attached ADU – An addition adjoining the primary home, either to the side, rear, or above an attached garage.
- Garage Conversion Contractor Services – Converting an existing garage into fully livable space, often one of the more cost-effective ways to add usable square footage to a property.
- Junior ADU (JADU) – Built by converting an existing portion of the home, such as a spare bedroom or attached garage. JADUs do not exceed 500 sq. ft. and function similarly to a standard ADU.
Their team handles pre-approval qualification and offers low-interest financing options. A property evaluation and zoning review are conducted on-site, followed by a site survey, preliminary planning, design, and engineering. Construction is project-managed from start to finish, with post-construction quality testing included upon completion.
Design, Planning, and Project Management
EcoSmart Builders positions itself as more than a construction resource. Their project management team works alongside homeowners to develop floor plans suited to specific needs and goals, whether that involves a granny flat, in-law suite, Casita, or a more straightforward garage conversion. They also assist in navigating the legal and regulatory requirements that come with ADU development, which can be complex despite recent easing of local regulations.
For homeowners who are uncertain about which type of ADU would add the most value to their property, EcoSmart Builders provides guidance during the evaluation phase. Their process is designed to reduce uncertainty around scope, cost, and timeline.
Beyond ADUs, EcoSmart Builders also takes on broader residential construction projects, including ground-up builds and fire rebuilds, with FSRT-certified expertise in the latter. Their construction approach emphasizes sustainability, with a stated commitment to delivering solutions that address current needs while maintaining long-term structural integrity.
EcoSmart Builders serves homeowners across Southern California, with a particular focus on Los Angeles County, where demand for accessory dwelling units continues to grow in response to housing availability challenges.
