Adding on to an Amityville home — whether a creek-front Colonial that needs a second story or a ranch that needs an in-law suite — takes a contractor who knows the Village permit process, flood-zone rules, and historic architecture.
Home additions in Amityville are more complex than in many other communities because of the range of factors at play. The Village Building Department reviews additions for zoning setbacks and code compliance. Creek- and bay-front lots bring FEMA flood-zone requirements into the picture, including base flood elevation standards that must be met and sometimes trigger a full evaluation of the existing structure. Historic homes near the village green require additions that are designed to respect the original architecture. Milton's Construction has navigated all of these conditions and handles every project with one in-house team from design through final inspection.
We build dormers, second stories, rear additions, garage conversions, in-law suites, and full ADU builds. For waterfront properties, we also do structural elevation work to bring homes into compliance with current FEMA standards. Whether the goal is more living space, a conforming addition on a flood-zone lot, or an ADU for a family member, call or text 631-741-0199 to schedule a free written estimate. We manage the Village permit, any required Town of Babylon review, and DEC coordination where it applies.

Adding to a Victorian or Colonial near Amityville Village Green is an exercise in proportion, materials, and design discipline. The addition needs to read as intentional from the street rather than tacked on, which means matching rooflines where possible, specifying siding and trim that align with the original, and keeping window proportions consistent. We design these additions in-house and review early drawings with the Building Department before committing to a full permit set, which saves time and avoids revisions later.
For creek- and bay-front properties in FEMA flood zones, any addition must be designed to the base flood elevation for that lot, and in many cases the permit review will evaluate the entire structure for compliance. We obtain the elevation certificate for your lot, determine the required finished floor elevation, and build the addition to those standards. In some cases it makes financial sense to elevate the whole home at the same time, and we provide the options and costs so you can make an informed decision.


Additions in the Incorporated Village of Amityville require a building permit, and the review covers zoning compliance, setbacks, lot coverage, and construction code. Waterfront lots may also need a Town of Babylon approval and, depending on proximity to tidal wetlands, a DEC permit. We manage that entire permit stack as part of the contract. You do not need to file separately or coordinate between agencies.
We provide free written estimates for every addition project. The estimate covers design, permits, all labor and materials, and the inspection process. Call or text 631-741-0199 to get started.
Yes. Second-story additions on Amityville ranches are one of our most common projects. We evaluate the existing foundation and first-floor framing to determine what upgrades are needed before building up, include those in the estimate, and file the full permit set with the Village Building Department. The result is a properly engineered addition that the inspectors sign off on without complications.
Yes, but the addition must meet the base flood elevation requirements for your specific lot, and the permit review may evaluate the whole structure. We obtain your elevation certificate, determine the required finished floor height, and design the addition accordingly. If elevating the house is part of the conversation, we provide those costs as well so you can compare options.
We work with the Amityville Building Department early in the design process, before the full permit is submitted, to make sure the addition will meet any applicable review criteria. Matching existing materials, maintaining roofline proportions, and using window patterns consistent with the original structure are all part of how we approach these projects from the first sketch.
