The ADU Pro® is a licensed, full-service accessory dwelling unit contractor headquartered in Chino, California, serving homeowners across Orange County, Los Angeles County, and Riverside County. Unlike general remodeling companies that occasionally take on ADU projects, The ADU Pro® is exclusively focused on accessory dwelling units — a specialization that allows the company to deliver a highly refined and efficient process tailored specifically to ADU construction throughout Southern California.

Their singular focus on ADUs is backed by more than 30 years of broader construction experience. Before launching The ADU Pro®, the team spent decades building residential homes, commercial properties, multi-family developments, and infrastructure projects across Southern California. That background gives them the technical depth to anticipate and solve complex construction challenges long before they become costly delays for homeowners.

A Full-Service ADU Contractor from Start to Finish

The ADU Pro® manages every stage of the accessory dwelling unit process under one roof, giving homeowners a single point of accountability throughout the project. Their comprehensive approach includes:

Site assessments and feasibility reviews
Custom ADU design and planning
Structural engineering
Permit applications and city coordination
Construction management
Final inspections and walkthroughs

By keeping design, permitting, and construction integrated within one team, clients avoid the communication gaps and delays that often occur when multiple vendors are involved.

Specialized ADU Solutions for Southern California Homeowners

As a dedicated ADU builder, The ADU Pro® works with homeowners seeking a wide range of accessory dwelling unit solutions, including:

Detached ADUs
Garage conversions
In-law suites
Granny flats
Backyard cottages
Rental income units
Multigenerational living spaces

Their team works closely with homeowners to determine the most practical and cost-effective solution based on lot size, zoning regulations, property layout, and long-term goals.

Local Expertise Across the Tri-County Area

Strategically headquartered in Chino, CA, The ADU Pro® is positioned near the center of the areas they serve, allowing the company to efficiently manage projects across Orange County, Los Angeles County, and Riverside County. Being located within close proximity to most job sites enables faster site visits, streamlined permit coordination, and more responsive project oversight compared to contractors operating from outside the region.

Their familiarity with Southern California zoning requirements, permitting departments, setback regulations, and local construction standards helps homeowners navigate a process that can otherwise become overwhelming and time-consuming.

Built Around Accountability and Experience

The ADU Pro® places a strong emphasis on communication, transparency, and project accountability. Homeowners work with a coordinated team that oversees the project from the earliest planning stages through final completion, helping ensure timelines, budgets, and expectations remain aligned throughout the build.

Their decades of hands-on construction experience, combined with an exclusive focus on accessory dwelling units, position The ADU Pro® as a specialized ADU contractor for homeowners seeking a streamlined, professional, and locally experienced partner in Southern California.
