About Norco ADU Builder

A locally focused ADU contractor dedicated to one thing: helping Norco homeowners add value, income, and living space to their properties.

Why We Focus on Norco

Norco's horse properties and large lots create unique ADU opportunities that most contractors aren't equipped to handle. Working on equestrian-zoned parcels, navigating workshop and barn conversions, and understanding the agricultural setback requirements that come with R-A zoning — that's our specialty.

Our service area covers Norco, Corona, Eastvale, Mira Loma, Jurupa Valley. We don't try to be everything to everyone across all of Southern California. We know these specific cities, their planning departments, their soil conditions, and their neighborhoods. That local knowledge is what keeps projects on schedule and on budget.

What We Do

We are a full-service ADU design-build operation. That means we handle every phase of your project under one roof — from the first site assessment through final city inspection sign-off. The services we provide:

  • Site assessment and lot eligibility review
  • Architectural design and structural engineering
  • Complete permit management — submission through approval
  • All construction trades (foundation, framing, electrical, plumbing, HVAC, finishes)
  • Final inspection coordination and Certificate of Occupancy
  • Guidance on ADU design styles, sizing, and rental optimization

Our Service Area

We serve Norco, Corona, Eastvale, Mira Loma, Jurupa Valley and the surrounding Western Riverside County communities. Our service area is intentionally focused — we'd rather know one region deeply than spread thin across all of Southern California.
