5 Reasons This 3rd-Generation Bay Area Contractor Leads in ADU Design-Build

Alamo, United States – May 7, 2026 / United Constructors Inc. /

United Constructors Inc. (UCI), a family-owned general contractor based in Alamo, California, has launched a comprehensive ADU design-build package tailored for Contra Costa County homeowners. The announcement responds to sustained demand across the region as California continues to prioritize accessory dwelling unit development as part of its statewide housing strategy. UCI, now in its third generation of family ownership, brings more than 30 years of hands-on Bay Area construction experience to the new offering.

A Family Legacy Built on Bay Area Craftsmanship

UCI’s roots in the Bay Area span three generations, giving the firm a depth of regional knowledge that informs every project it undertakes. The company’s work across communities including Walnut Creek, Lafayette, Danville, Moraga, Orinda, Pleasant Hill, and San Ramon reflects decades of relationships with local homeowners, municipal planning departments, and subcontractors. As an established ADU contractor Bay Area homeowners have relied on since its founding, UCI’s new package formalizes a service offering that aligns with where the housing market is heading.

“We have been building in this region for over 30 years, and three generations of our family have put their names on every project we complete,” said Cash Payne, Project Director of United Constructors Inc. “With California’s ADU push creating real opportunity for homeowners to add long-term value to their properties, we designed this package so that our clients in Contra Costa County have one trusted team from the first sketch to the final walkthrough.”

5 Reasons Contra Costa County Homeowners Are Choosing UCI for ADU Projects

1. Three Generations of Hands-On Bay Area Expertise

UCI’s construction experience spans more than three decades of active work across the San Francisco Bay Area. That continuity means the team understands local soil conditions, building codes, and neighborhood-specific design sensibilities in ways that newer firms cannot replicate.

2. Proprietary 3D Design Renderings

Before a single permit is filed or a foundation is poured, UCI provides clients with detailed 3D renderings of their planned accessory dwelling unit. This visual planning step allows homeowners to make informed decisions about layout, finishes, and scale before any construction costs are committed.

3. True Design-Build Model

As a dedicated ADU design build Contra Costa County firm, UCI manages every phase of the project under one roof. Design, permitting, construction, and the final walkthrough are all handled by the same coordinated team, reducing the communication gaps and scheduling conflicts that occur when homeowners hire separate architects and contractors.

4. Full Permitting Management Across Contra Costa County

Navigating local permitting requirements is one of the most time-consuming aspects of any ADU project. UCI handles the complete permit process on behalf of its clients, including documentation, agency submissions, and inspections specific to Contra Costa County jurisdictions. This end-to-end management removes a significant administrative burden from the homeowner.

5. Free Consultation and a Licensed, Bonded, Insured Quality Guarantee

Every UCI project begins with a no-cost consultation, giving homeowners a clear picture of scope, timeline, and budget before making any commitments. As a licensed, bonded, and insured accessory dwelling unit contractor, UCI stands behind the quality of its work with formal guarantees that protect the client through and after construction.
