Frequently Asked Questions

Matrix Group One is a home remodeling contractor with 40+ years of construction experience serving the Peninsula—from San Francisco through Santa Clara County. We specialize in ADUs, additions, whole-home remodels, and kitchens.

How long does a typical addition or ADU take?
Timelines vary by scope and city review:
  • ADUs: ~3–5 months build time after permits (detached units may take longer).
  • Additions: ~4–8+ months depending on structure and MEP scope.
We provide a critical path schedule and weekly updates so you always know what’s next.
Do I need permits? Do you handle them?
Yes—most projects require permits, especially structural work, new circuits, plumbing runs, or new openings. We prepare plan sets, submit to your city, coordinate plan check comments, and schedule inspections.
What budget ranges should I expect?
Budgets depend on size, finishes, and site conditions:
  • Typical ranges: $100k–$200k, $200k–$300k, $300k–$500k, $500k+ based on scope and complexity.
You’ll see line-item pricing and allowance schedules before you commit.
Can I live in my home during construction?
Often yes for additions; we isolate work zones and protect pathways. For detached ADUs, disruption is lower; for interior work, expect noise during demo and rough-in phases.
What’s included in your design support?
Space planning, elevations, structural coordination, energy systems, lighting layouts, and finish schedules—collaborating with your architect/designer if desired.
How do selections affect the project?
Lead times for windows/doors, cabinetry, stone, and specialty fixtures can add weeks. We lock selections early and order ahead to keep milestones on track.
Do you offer warranties?
Yes—labor warranty on our workmanship plus manufacturer warranties on materials. We complete a formal punchlist and provide a closeout package.
What makes Matrix Group One different?
40+ years of Peninsula experience, permitting expertise, and a true design-build approach—one accountable team from feasibility to handover.
