Second Story Additions in Westborough
Adding a Floor to Your Westborough Home
West Main Street and Vintonville are historic districts, and Fay Mountain rises as the highest point in town. For many Westborough homeowners, building up rather than out adds a full or partial floor without giving up the yard, and an engineer evaluates the house before any design is drawn.
Typical second story projects in Westborough:
- Second stories for older houses on West Main Street
- Walls and footings reinforced where needed
- Wiring, plumbing, and HVAC carried to the new floor
- Roof removal in planned sections
- Temporary shoring while the house is open

Key Facts for a Second Story in Westborough
Ground near Lake Chauncy, Mill Pond, and Cedar Swamp Pond can hold water, so foundations and drainage need review. Before a second story is drawn up, we review the panel, water heater, and HVAC, organize materials ahead, and find out whether the added height needs zoning review.
The starting point for a new floor:
- The footings below the walls
- Beams and posts that may be needed
- A place for the new staircase
- Shoring while the roof is off
- Drains and supply lines for bathrooms upstairs
Going up can make sense when:
- Lot lines leave little room beside the house
- You want space for relatives or guests
- Moving does not feel like the right answer
- One wing could carry a new level
- You need more space on the same footprint
We study the house during the estimate and bring in an engineer before design, so the second story is sized around what the foundation and walls can hold, not around a guess.
Our process
How We Build a Second Floor in Westborough
Temporary support keeps the house steady while sections of the roof come off, and beams, posts, or larger footings are added where the engineer calls for them. Then the new floor, walls, and roof are framed and closed, the systems are run to the new level, and the finishes come last.

Cost factors
Second Story Cost Factors in Westborough
Pricing a second story for a Westborough house begins with the structure, not the floor plan. How big the new floor is, how much reinforcement is needed, removing the old roof, stairs and interior connections, bathrooms upstairs, and materials and permits all play a part, so the number comes after the structural evaluation.
What sets the price:
- A whole or partial new floor
- Engineering and reinforcement
- Temporary support during roof removal
Also in the estimate:
- Plumbing, wiring, and HVAC on the new level
- Upgrades to the panel or HVAC
- Materials, finishes, and permits

FAQ
Second Story Additions in Westborough: Common Questions
Building up raises a handful of common questions for Westborough homeowners. These answers explain the permit and the zoning review, what the existing structure can carry, what happens to the roof, and how to get started. For anything else, give us a call, and we will help you sort it out.
Does building up in Westborough require a permit?
Yes, it does. Building a second story calls for a building permit with structural drawings, and many towns also review the building height and zoning. ML20 General Construction works with the engineer, files the applications with the town, and schedules the inspections from the structure to the final work.
Can my Westborough house carry a second floor?
That depends on what the engineer finds. Most houses were framed to carry a roof, not another floor, so the engineer checks the foundation, the walls, and the floor framing before design. Where more strength is needed, we add beams, posts, larger footings, or new framing so the load reaches the foundation along a safe path.
Do you take the old roof off?
Most of the time, yes. Temporary support holds the house steady while the roof is removed in planned sections. For a partial one, only one section may need to open. Materials are staged in advance, so the new floor is framed and closed as soon as possible, with open areas covered each evening.
