FAQ

We build custom homes, home additions, full home remodels, ADUs (Accessory Dwelling Units), and light commercial tenant improvements. Our work is based on architectural and engineering plans, with close coordination between the design team, consultants, and construction.

CALIBUILDER specializes in ground-up custom home construction, additions, structural remodels, ADUs, and commercial build-outs. We focus on executing projects from approved plans with a structured, detail-driven construction process and coordinated project management.

We primarily build from client-provided plans prepared by architects and engineers. If you are early in the process, we can collaborate during pre-construction and connect you with trusted design professionals to move your project forward.

We are based in San Mateo and serve projects across San Mateo County, Santa Clara County, and the greater Bay Area, including cities such as Palo Alto, Menlo Park, Redwood City, San Jose, and surrounding areas.

You can start by contacting us through our website or scheduling a call. If you already have plans, we can review them and provide a proposal. If you are in early stages, we can guide you through next steps and pre-construction planning.

No. While final pricing requires a complete plan set, we can review conceptual or schematic designs and provide early budgeting guidance. We also offer pre-construction collaboration to help align design with budget.

We review your plans in detail, perform quantity takeoffs, and prepare a structured estimate by trade. Our proposals include scope of work, assumptions, allowances, and cost breakdowns. We may also raise RFIs if clarification is needed before final pricing.

Our construction service includes project management, coordination of licensed trades, scheduling, inspections, and installation. We typically provide labor and rough materials, while many finish materials (fixtures, cabinets, finishes) are owner-selected to maintain flexibility and control.

ADU costs vary depending on size, design, site conditions, and utility connections. In the Bay Area, costs are typically influenced by structural requirements, permitting, and finish selections. We provide project-specific estimates once plans are available.

Key factors include layout changes, structural modifications, utility upgrades, appliance selections, and permitting requirements. Early planning and clear scope definition help avoid delays and budget overruns.

Look for a contractor with experience in similar project types, clear communication, structured proposals, and the ability to coordinate with architects and consultants. A transparent scope of work and detailed estimate are key indicators of a well-managed project.

Clear plans, defined scope, and early coordination are essential. We help manage costs by identifying unknowns early, structuring estimates properly, and maintaining communication throughout construction to avoid unexpected changes.

Project timelines depend on scope, permitting, and complexity. ADUs and remodels may take several months, while custom homes and large additions take longer. A detailed schedule is provided once the project scope is defined.

Yes. As the general contractor, we coordinate permitting, inspections, and compliance with local city requirements, including construction management, waste management, and site logistics.

In some cases, yes, depending on the scope of work. However, construction may impact utilities, access, and daily living conditions. We discuss this in advance and plan accordingly.

We maintain consistent communication through project updates, messages, and shared documentation. Clients receive regular progress updates, photos, and coordination details throughout construction.

Yes. In addition to residential construction, we also complete commercial tenant improvements and build-outs, coordinating with business owners, designers, and inspectors.
