Home additions and extensions in Bohemia, NY — dormers, second stories, rear extensions, and in-law suites for ranch and Cape Cod homes.
Bohemia has a lot of ranches and story-and-a-half Capes where families have outgrown the square footage but have no interest in moving. Those homes sit on full lots with room to grow, and the bones are usually solid enough to carry a second story or a rear extension without heroic structural work.
Milton's Construction does frame-to-finish additions. We handle the design, the Town of Islip permit application, the foundation or ledger work, the framing, and every trade through final inspection — all one in-house crew.
The most common projects in this part of Suffolk County are Cape Cod dormers — pushing out the roof to create full headroom on the second floor — and first-floor rear extensions that add a family room, a primary suite, or an in-law apartment. Second-story additions on ranches are also straightforward here because most of these homes sit on slab or a full basement with adequate footings.
In-law suites have their own considerations under Town of Islip zoning, including setback requirements and the definition of an accessory dwelling unit. We navigate that early in the process so there are no surprises after the framing is up.
All additions require a building permit through the Town of Islip Building Division. We prepare the drawings and applications, schedule the foundation, framing, and final inspections, and keep the project on the Town's required timeline.
Addition costs vary more than any other project type depending on size, scope, and whether a new foundation is needed. Rough ranges start in the low six figures for a modest dormer and go up from there.

Many can. We evaluate the existing foundation, footings, and framing before we commit to a scope. If reinforcement is needed, we include that in the plan and price rather than discovering it after demo.
Town of Islip has specific zoning requirements for accessory dwelling units, including setbacks and size limits. We research the rules for your specific parcel and design the addition to comply from the start.
A dormer on a Cape typically takes three to five months from permit approval to finish. A full rear extension or second-story addition is six to nine months. Weather and Town inspection scheduling affect the timeline, and we give you a realistic schedule upfront.
