WHY ARE WE
the Right
Choice

Building an ADU is more regulated than a standard addition, which is why working with an experienced ADU builder in Rancho San Diego, CA matters. Here's what makes Friendly Remodeling the preferred choice:

  • ADU-Specialized General Contractor: ADU code, zoning, setbacks, parking, and utility requirements are constantly changing — we stay current and steer you away from costly missteps.
  • Free ADU Feasibility Assessment: Before you spend a dollar on design, we'll tell you what's actually buildable on your lot given current Rancho San Diego, CA zoning, setback, and lot coverage rules.
  • Cost-Effective Design Options: Our pre-engineered ADU plans cut design and engineering fees significantly — you can still customize interior finishes and layout.
  • Fixed Price ADU Contracts: Detailed, all-in proposals including site work, utilities, permits, and finishes. No vague allowances that balloon at the end.
  • Single Point of Accountability: One contract, one project manager, one warranty across foundation, framing, MEP, finishes, and final inspection.
  • Rental-Ready Deliverables: If you're building to rent, we can deliver the ADU complete with appliances, blinds, and final touches so it's ready to list.
