Oakland presents unique challenges that national builders and out-of-town contractors often miss. Here is what we account for on every Oakland project.

An Oakland custom-home price needs a defined design and site scope. Request separate estimates for design, site preparation, foundations, framing, building systems, finishes, and permits. Ask which site investigations and approvals the estimate assumes. A square-foot rate alone does not explain those inclusions.

Architect-led. Alex Hamilton Li is a licensed architect and general contractor (CSLB #1078806). Most Oakland custom home builders are tradesmen-only. Having an architect on staff means design and construction stay aligned from day one. Transparent pricing. Every estimate is itemized line by line — materials, labor, permits, cleanup. You see exactly where your money goes before we start. Factory-trained installers. Every crew member is manufacturer-certified and vetted — licensed, bonded, insured

Hillside lots in the Oakland Hills add $50,000 to $200,000 for site preparation and foundation engineering. See the pricing table above for a detailed breakdown.

Yes. All new construction in Oakland requires a building permit from the Oakland Building and Planning Department.
