We hired them for a bigger renovation. Alex was very responsive, which I appreciated. We changed a couple requirements during the job and they worked with us on it without making it complicated. Overall, everything went pretty smooth and their quality of work is solid. I recommend them highly!

What areas do you serve?
We serve Northern California across three regions: the San Francisco Bay Area, Greater Sacramento, and the Central Valley. Our published guides cover 14 counties and 88 cities. Our Castro Valley and Sacramento offices support local estimating, permit coordination, and project planning across these regions.
How does billing and financing work?
Financing may be available for eligible projects with approved credit. Available terms depend on lender approval, project scope, and current programs. Your project manager can review the options that apply before work begins. We also accept checks, ACH, and major credit cards.
Are you licensed and insured?
Yes. Hamilton Exteriors holds CSLB License #1078806, active general liability coverage, and the required contractor bond. We also hold GAF Master Elite and James Hardie Elite Preferred credentials. We can provide current proof of coverage before work begins.
Do I need a permit for my exterior project?
Permit requirements depend on the project scope and local jurisdiction. Hamilton Exteriors coordinates required applications, plan documents, corrections, and inspections. Permit fees and allowances appear in the proposal before construction begins.
Why Choose an Architect-Led Custom Home Builder in Novato?
Most custom home builders in Novato are tradesmen-only — skilled at construction but not trained in architectural design. Hamilton Exteriors is different. Alex Hamilton Li is a licensed architect and general contractor, which means design and construction happen under one contract. This eliminates the coordination gaps between separate architects, engineers, and builders that cause 80% of budget overruns on custom home projects. With an architect-led design-build process, every material and syst
How Much Does a Custom Home Cost in Novato?
A Novato custom-home budget needs a project-specific written estimate. Ask for separate design, engineering, permit, site-work, construction, and finish costs. Confirm whether landscaping, appliances, utility work, and specialty features are included. Review allowances, exclusions, and change-order terms before treating the total as a fixed commitment.
How long does it take to build a custom home in Novato?
Custom home construction in Novato takes 12 to 18 months from permit approval. The design and permitting phase adds 4 to 8 months depending on architectural complexity and plan review timelines. Total timeline from initial consultation to move-in is typically 18 to 24 months.
Do I need a permit for a custom home in Novato?
Yes. All new construction in Novato requires a building permit from the Novato Building Department. We handle the entire permit process, including application, plan submission, and scheduling inspections.
Can I build a custom home on a hillside lot in Novato?
Yes, but hillside construction requires specialized engineering for foundations, retaining walls, drainage, and seismic bracing. Novato's western hills have excellent views but require geotechnical reports, soil testing, and engineered foundations. Retaining walls typically cost $200 to $500 per linear foot depending on height and soil conditions (Hamilton Exteriors 2024-2026 project data).
