Second Story Additions in Dedham
Adding a Floor to Your Dedham Home

For a second story in Dedham, an engineer reviews the foundation and walls first, and one general contractor coordinates the framing, roof work, systems, and new stairs that follow.

Local conditions
Going Up Instead of Out in Dedham
Route 128 and the busy roads near Dedham Square can slow trucks, so delivery windows are set ahead of time. 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 the roof is open.
What we check before design:
- The footings below the walls
- Posts and beams the engineer may call for
- A place for the new staircase
- Shoring while the roof is off
- Drains and supply lines for bathrooms upstairs
Signs a second story may fit you:
- Lot lines leave no room to the side or back
- You want space for relatives and guests
- Moving is not the answer
- One wing could carry a new level
- You want more space on the same footprint
We look at the house on the first visit and involve an engineer before anything is drawn, so the second story is planned around what the foundation and walls can carry, not around a guess.
Our process
Our Second Story Process in Dedham
A second story in Dedham follows a strict sequence: the engineer’s evaluation, temporary support, roof removal, reinforcement, framing, systems, and finishing. Each step is planned before the old roof is opened, because the house stays open to the weather until the new level is closed in.
- 01
Engineer’s Review
A structural engineer checks the foundation, walls, and load paths before anything is drawn.
- 02
Temporary Support
Temporary posts and beams keep the house steady while parts of the roof come off.
- 03
Opening the Roof
The existing roof comes off in planned sections, with open areas covered at the end of each day.
- 04
Reinforcement
Posts, beams, and footings are added where the new load requires them.
- 05
New Floor and Walls
The walls, floor, and roof of the new level are framed and closed as soon as possible.
- 06
Systems, Then Finishes
Electrical, plumbing, and HVAC reach the new level, followed by drywall, insulation, and trim.

Cost factors
What Affects Second Story Costs in Dedham
Pricing a second story for a Dedham house starts with the structure, not the floor plan. How big the new floor is, how much reinforcement is needed, the roof design and removal, stairs and interior connections, bathrooms upstairs, and permits and materials all count, so the price follows the engineer’s evaluation.
Main cost drivers:
- A full or partial new floor
- The structural evaluation and reinforcement
- Shoring and roof work
Other items we price:
- Plumbing, wiring, and HVAC upstairs
- Upgrades to the panel or HVAC
- Permits, materials, and finishes

FAQ
Second Story Additions in Dedham: Common Questions
Adding a floor raises several questions for Dedham homeowners. The answers below explain permits and the height review, whether the structure can carry a new floor, what happens to the roof, and the first step. If something is missing, give us a call, and we will explain the options.
Does building up in Dedham require a permit?
Yes, it does. Adding a floor requires a building permit with structural drawings, and many towns review the building height and zoning. Our team coordinates the engineer, prepares the applications for your house, and books the inspections from the structure to the final work.
Can my Dedham house carry a second floor?
It depends on the structural evaluation. Many houses were framed to carry a roof, not a second floor, so a structural engineer reviews the foundation, the walls, and the floor framing before anything is drawn. When more strength is needed, we add beams, posts, larger footings, or new framing so the added weight travels down to the foundation safely.
Do you take the old roof off?
Most of the time, yes. Temporary support holds the house stable while the roof comes off in sections we plan ahead. For a partial addition, just one section may need to open. We stage the materials beforehand, so the new floor is framed and closed quickly, with the open sections covered each evening.
What happens first when I want to build up in Dedham?
It starts with a no-cost in-home consultation: request one online or call (978) 917-9072. We check the roof and the structure of your Dedham house, listen to your plans for the new floor, and explain the structural evaluation before the design work. No obligation applies.
