General Construction in Hillsborough, CA

The McCarthy Company provides general construction and design-build services for Hillsborough homeowners planning major residential projects. From new home construction and ADUs to additions, whole-house renovations, and deck work, we help organize work that needs thoughtful planning and careful execution.

If you are evaluating a major remodel, preparing a site for a new home, or coordinating several trades for one property, we can review the scope, discuss practical options, and move the project forward with clear communication. We work with homeowners in Hillsborough, throughout San Mateo County, and across the San Francisco Peninsula from our base in La Honda.

General construction help

For important residential projects, homeowners often need more than a single trade. A new home, ADU, addition, or full renovation can involve planning, engineering, framing, finishes, utilities, and close coordination between multiple crews. We handle that coordination so the work stays connected from the first discussion through completion.

The McCarthy Company is set up for substantial residential construction, not just isolated repair work. That includes projects where the structure, layout, and long-term use of the home all need to be considered together. We also take on deck construction and replacement, foundation and concrete work, roofing, rot and structural repair, and related residential work when it is part of a larger project.

• ADU construction
• Home additions

Hillsborough homes

Hillsborough properties often call for construction planning that respects the existing home while allowing for meaningful improvements. Some owners want to expand living space with an addition. Others are looking to build a separate ADU, replace aging exterior elements, or rework the full house to better fit current needs. In each case, the starting point is the same: understand the property, define the scope, and make sure the construction plan fits the home.

We pay close attention to the way a project affects the rest of the property. That includes how new work connects to the existing structure, where foundation or framing work may be needed, and how trades should be sequenced so the project is managed in a practical way. For Hillsborough homeowners, the goal is not just completing the work, but completing it carefully so it serves the home for the long term.

Common project goals

1. Add usable space: Home additions and ADUs can create room for family, work, or separate living arrangements while keeping the house functional during the process.
2. Rework the layout: Whole-house renovations and larger remodeling projects can improve how rooms relate to one another and how the home is used day to day.
3. Refresh the structure: Roofing, structural repair, foundation work, and exterior updates help address important construction needs while supporting other improvements.

How we build

Every major project starts with understanding what the homeowner wants the property to do. From there, we evaluate the existing conditions, identify the scope of work, and discuss the sequence needed to move ahead. On some projects that means design coordination. On others it means bringing in engineering, structural planning, or specific trades at the right stage.

Once the plan is set, we manage construction with a focus on practical coordination and steady communication. That can include framing, foundation work, roofing, siding, windows and doors, electrical, plumbing, HVAC and heat pumps, and finish work tied to the larger build. The process is straightforward: plan well, build carefully, keep the homeowner informed, and close out the work with attention to detail.

Typical steps

1. Review the property: We look at the existing home, site conditions, and the intended scope.
2. Plan the work: We define what needs to happen, what trades are involved, and how the project should move forward.
3. Coordinate construction: We manage the sequence of work and keep the project moving in an organized way.
4. Complete carefully: Final details matter on residential work, especially when multiple parts of the home are connected.

Available services

Homeowners in Hillsborough can turn to us for a range of residential construction services, with the strongest focus on larger projects that shape how a home is used and maintained. That includes new home construction, ADU construction, home additions, design-build services, and whole-house renovation.

We also handle deck construction and replacement, foundation and concrete work, rot repair and structural repair, and roofing. Kitchen remodeling and bathroom remodeling are available as part of larger residential projects, especially when they are part of a broader renovation or addition. When a project involves several scopes at once, we can help coordinate the work so the result feels planned rather than pieced together.

For homeowners comparing contractors, it helps to work with one company that understands both the structural side and the day-to-day build. That matters when a project includes an addition tied into the existing home, an ADU that needs careful placement and coordination, or a renovation that affects multiple rooms and systems.

What matters most

Hillsborough homeowners usually want a contractor who can handle a serious project with care and clarity. That means paying attention to details that may not be visible at the start, such as how the structure supports new work, how materials are selected for long-term use, and how different parts of the project fit together.

The McCarthy Company is built around that kind of work. We focus on residential construction where planning matters, coordination matters, and the finished result needs to support everyday use for years to come. If your project begins with a new home, an ADU, an addition, or a major remodel, we can help shape the work from the early stages through completion.
