Add space without giving up the neighborhood.

Additions and second stories can completely change how your home lives—new suites, multigenerational layouts, better circulation, and light that finally reaches the spaces that felt dark. HelixADU leads feasibility, scope planning, permitting coordination, and the client experience. Construction is performed under separate contract by independent, properly licensed and insured California contractor partners.

Best for

• Growing families and multigenerational households
• Primary suites, guest suites, or ADU-style wings
• Reconfiguring circulation to add privacy and flexibility

How HelixADU keeps additions on track

• Clarify goals, budget guardrails, and zoning realities
• Coordinate design + engineering partners (as needed)
• Guide permitting and milestone approvals
• Pair you with the right licensed & insured contractor partner

Logistics note: We focus on projects that are free/clear for construction—no homeowner living in the active work area/unit during construction. We’ll review access, staging, and temporary housing options early.
