General Construction in Atherton, CA

The McCarthy Company serves Atherton homeowners who are planning substantial residential construction, from new homes and ADUs to major remodels, additions, and decks. If you are comparing contractors for a project that needs careful planning and steady coordination, we can help you evaluate the scope and move toward a clear construction plan.

We are based in La Honda and work throughout San Mateo County and the San Francisco Peninsula, including Atherton. Homeowners often reach out when they are ready to build on a lot, expand an existing house, or take on a whole-property renovation that requires structural, design, and trade coordination. The next step is a practical conversation about your goals, your property, and the type of work needed to complete the project well.

General construction help

The McCarthy Company is a general construction contractor and design-build company focused on significant residential work. In Atherton, that often means a project where one contractor needs to keep many moving parts aligned, including planning, structural considerations, specialty trades, and the day-to-day progress of construction. We work best when the homeowner wants a thoughtful process and a finished result built for long-term use.

Our work is centered on the kinds of projects that shape a home rather than simply refresh it. That includes new home construction, ADU construction, home additions, whole-house renovations, and deck construction and replacement. We also handle related work that often comes with these projects, such as foundation and concrete work, roofing, rot repair and structural repair, siding, windows and doors, and residential electrical, plumbing, and HVAC coordination when needed.

Atherton property needs

Atherton homeowners often come to us with projects that call for careful attention to the existing house, site conditions, and the overall scope of work. Some properties are best served by a clean addition that preserves the character of the home while improving how it functions. Others need more substantial planning, especially when a new house, detached ADU, or whole-house renovation is involved.

For larger residential projects, the early decisions matter. We look at the goals for the property, how the work will fit the home, and what construction steps may be needed to carry the project through from planning to completion. If engineering or specialty trades are part of the job, we help coordinate those pieces so the work stays connected and practical.

Common project types

• New homes: Ground-up residential construction for homeowners starting with a fresh build.
• ADUs: Detached or accessory living spaces planned as part of the property.
• Additions: New square footage that extends the usefulness of an existing home.
• Whole-house renovations: Broad updates that require a coordinated construction approach.
• Decks: New and replacement deck construction designed to integrate with the home.

The goal is to keep the project organized around the home as a whole rather than treating each trade as a separate problem.

Design-build process

Design-build work is a good fit for homeowners who want one company to help connect the planning and construction phases of a residential project. At The McCarthy Company, that starts with understanding what you want the finished home to do for you, then evaluating the existing property and the work required to get there. From that point, we move into scope development and design coordination, followed by the construction itself.

1. Project goals: We start by listening to what you want to change, improve, or build.
2. Property review: We assess the home and site so the plan reflects real conditions.
3. Scope and design: We help define the work and coordinate the pieces that need to fit together.
4. Engineering and trades: When needed, we coordinate structural input and specialty trades.
5. Construction: We manage the work carefully, keeping the project moving and communicating as it progresses.

This approach is useful for larger projects where decisions made early can affect the entire build. It also gives homeowners a clearer path from idea to finished construction.

Working with us

Homeowners usually contact us when they are ready to move from a general idea to a real construction plan. That may mean building a new home, creating an ADU for a property, expanding the main house, or taking on a renovation that reaches beyond surface finishes. We aim to be direct about what a project will involve and practical about how the work should be organized.

Clear communication matters throughout the process. We keep the focus on the project itself, the sequence of work, and the details that shape a durable result. For Atherton homeowners, that often means balancing design goals with construction realities so the finished home feels intentional and well built.
