Costs & budgets
How much does an ADU cost in Newport Beach?
Newport Beach ADUs cost $85K–$165K for a garage conversion and $230K–$420K for a detached new build in 2026 — typical of the Los Angeles market. Lot conditions, utility upgrades, and finish tier are the biggest swing factors.
Newport Beach construction labor and permit fees track the broader Los Angeles market within ±10%. Hillside parcels, historic overlays, and corner lots can each add 8–15% to the base number.
Two-thirds of Newport Beach ADU budgets land within ±15% of the midpoint when scope is locked early. Most cost surprises come from late selection changes or undiscovered site conditions.
