ADU Construction Services by Quality First Builders
Building an accessory dwelling unit in Los Angeles involves more than hiring a general contractor. It requires a team with working knowledge of local zoning laws, lot constraints, and permit timelines. Quality First Builders has been providing ADU construction services across LA County since 2014, helping homeowners convert garages, backyards, and underutilized spaces into functional accessory dwelling units.
As an experienced ADU builder, Quality First Builders handles the full scope of work in-house. This includes custom design, permit documentation, construction, and final inspections. There are no handoffs to outside vendors, which means homeowners have a single point of contact throughout the entire project.
What They Build
Quality First Builders works on a range of ADU types to suit different property configurations and homeowner goals:
- Detached ADUs — standalone backyard cottages and granny flats built on existing residential lots
- Garage conversions — transforming existing garages into livable accessory dwelling units
- In-law suites — attached or interior units designed for multigenerational living arrangements
- Junior ADUs (JADUs) — smaller units created within the existing footprint of a home
Whether the goal is generating rental income, creating a guest house, or accommodating family members, Quality First Builders approaches each project based on the specific needs of the homeowner and the constraints of the property.
How They Work
Quality First Builders operates with licensed and bonded crews and maintains clear project timelines throughout the construction process. Their in-house approach means that design, permitting, and building are all managed by the same team, reducing the coordination issues that can arise when multiple contractors are involved.
For homeowners in LA County considering an accessory dwelling unit, working with a contractor familiar with local regulations can make a meaningful difference in how smoothly a project moves through the permitting and construction phases. Quality First Builders has built that familiarity over more than a decade of ADU work in the region.
Their services are suited to homeowners looking for a structured, managed process — from the initial design consultation through to the final inspection sign-off.
