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.

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.

### Ground-Up Construction Complete control over every detail — layout, materials, energy systems, and style. Design-build under one contract from foundation to finishing touches. We build on existing lots throughout Mountain View, including the Old Mountain View neighborhood, the Shoreline area, and the Cuesta Park and Monta Loma residential districts.

### Architect-Led Design-Build Most custom home builders are tradesmen who subcontract design to an outside architect. Hamilton Exteriors is different. Alex Hamilton Li is a licensed architect and general contractor who designs your home and builds it — under one contract, with one point of accountability. This eliminates the expensive redesign cycles that happen when an architect designs something the builder can't build within budget.

A Mountain View custom-home estimate needs more than a floor-area figure. Provide the design, finish choices, and lot information. Ask for separate design, engineering, permit, site-work, construction, and landscaping costs. Confirm grading and utility connections in the written scope rather than assuming they are included.

To budget a Mountain View custom home, request pricing for the proposed plans and lot. Separate construction costs from design, engineering, permits, site preparation, grading, and utility work. Confirm allowances and exclusions in writing. A project-specific estimate is needed before choosing a total budget.

Custom home construction in Mountain View takes 12 to 18 months from permit approval. The design and permitting phase adds 4 to 8 months depending on architectural complexity and Mountain View's plan review timelines. Total timeline from initial consultation to move-in is typically 18 to 24 months. Your dedicated project manager provides weekly progress updates and coordinates all subcontractor sequencing.
