Second Story Additions in Watertown
A New Upper Floor for Your Watertown House
The Perkins School for the Blind calls the town home, and the Massachusetts Turnpike is a short drive away. For a second story in Watertown, an engineer checks the foundation and walls first, and one general contractor schedules the framing, roof work, systems, and new stairs that follow.
What a second story in Watertown can include:
- Second stories for older homes set close together
- Full or partial floors over the existing house
- New stairs linked to the rooms below
- Walls and footings reinforced where needed
- Wiring, plumbing, and HVAC carried to the new floor
Local conditions
Building Up on Watertown Houses
Ground near the Charles River may hold moisture, so drainage and footings are looked at early. On a second story, the existing structure is checked by an engineer, walls and footings are reinforced where needed, and the house is protected while it is open to the weather.
Where a second story starts:
- How loads travel to the ground
- The new roof over the added level
- Stairs and openings between both floors
- Wiring extended to the new level
- HVAC for the upper floor
Building up may make sense when:
- The lot has little space to build out
- You need several bedrooms and another bathroom
- You would rather keep the yard as it is
- Your family is growing faster than the house
- You want to stay in the neighborhood
During the in-home visit, we check the roof, where the new staircase can go, and the electrical panel, water heater, and HVAC, because all three affect how the new level is laid out and what it costs.
Our process
From Roof Removal to New Floor in Watertown
Temporary support holds the house steady while sections of the roof come off, and posts, beams, or larger footings are added where the engineer requires them. Then the new floor, walls, and roof are framed and closed, the systems reach the new level, and the finishes follow.
- 01
Engineer’s Review
A structural engineer reviews the walls, foundation, and load paths before anything is drawn.
- 02
Shoring
Temporary posts and beams hold the house stable while parts of the roof come off.
- 03
Roof Removal
The existing roof is removed in planned sections, with open sections covered each day.
- 04
Structural Reinforcement
Beams, posts, and footings go in where the engineer calls for them.
- 05
Framing the New Floor
The walls, floor, and roof of the new level are framed and closed as soon as possible.
- 06
Systems, Then Finishes
Wiring, plumbing, and HVAC reach the new level, followed by insulation, drywall, and finishes.

Cost factors
Pricing a New Floor in Watertown
Pricing a second story in Watertown starts with the structure, not the floor plan. The size of the new floor, the reinforcement required, removing the old roof, stairs and interior connections, bathrooms upstairs, and materials and permits all play a part, so the number follows the engineer’s evaluation.
Largest cost factors:
- How large the new level will be
- Posts, beams, or larger footings needed
- The new roof’s design
More items in the price:
- Stairs and openings between floors
- Each bathroom on the new floor
- Material and finish choices and permits

FAQ
Second Story Additions in Watertown: Common Questions
Many Watertown homeowners considering a second story ask about the same four things: permits, the structure, the roof, and how to start. Below, each one gets a short answer in plain words. If your question is not here, reach out and we are glad to help.
Does building up in Watertown require a permit?
Yes, it does. Building a second story requires a building permit backed by structural drawings, and many towns review the height of the house and zoning. ML20 General Construction coordinates the engineer, prepares the applications for your house, and schedules the inspections from the structure to the final work.
Can my Watertown house carry a second floor?
That depends on what the engineer finds. Most houses were framed to carry a roof, not another floor, so a structural engineer reviews 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 added weight travels down to the foundation safely.
Will the existing roof be removed?
Most of the time, yes. Temporary support keeps the house stable while the old roof is removed in sections we plan ahead. For a partial addition, only one section may need to open. We stage the materials beforehand, and the new floor is framed and closed quickly, with open areas covered at the end of each day.
