If you are shopping for a new home on Long Island and want the speed of factory construction without sacrificing quality, a custom modular home is worth a serious look. The first decision most buyers face is style: ranch, cape cod, two-story, raised ranch, split level, or chalet. Each floorplan suits a different lot, budget, and family situation. This guide breaks down what you actually get with each style, what it costs in the current market, and what to expect from the permit and delivery process in Nassau and Suffolk counties.
What Makes a Modular Home Different
Modular homes are built in climate-controlled factories as a series of modules, then transported to your site and assembled on a permanent foundation. Because the modules are built to the same New York State residential code as site-built homes, they appraise and finance the same way. The practical upside is speed: once your foundation is set and local permits are approved, the modular portion of construction is typically complete in 30 to 60 days on-site, versus 6 to 12 months for comparable stick-built work.
At Milton's Construction we handle the full process — architecture and design, site prep, frame-to-finish construction, licensed plumbing, and HVAC — so you deal with one contractor from permit application through final walk-through. We also work with Enhancify on construction financing options that let you check your rate without affecting your credit score.
Ranch
A single-story ranch is the most accessible modular style and the most popular on flat Long Island lots where a full basement foundation is straightforward. Everything — bedrooms, bathrooms, kitchen, and living areas — sits on one level, which makes it ideal for aging-in-place, families with young children, and anyone who wants to avoid stairs permanently.
- Typical size: 1,100 to 2,400 sq ft on the main floor
- Foundation: full basement or crawlspace; slab is less common in NY due to frost depth requirements
- Cost range: roughly $180 to $260 per sq ft all-in (modules plus site work, foundation, and utility connections) — wide variation by finish level and lot conditions
- Best for: level lots, accessibility needs, empty nesters downsizing from larger colonials
One thing to keep in mind on Long Island: ranch homes sit on more footprint than a two-story with the same living area, which can matter on narrow quarter-acre lots in older subdivisions. Your zoning setbacks and lot coverage limits will determine what fits.
Cape Cod
The cape cod is arguably the native style of Long Island housing stock. A steep roofline brings usable living space into the upper half-story, typically dormered out for one or two bedrooms and a bathroom. It is a smart way to get 1,600 to 2,200 sq ft of finished space on a modest footprint, and it blends naturally into established neighborhoods in Suffolk County towns like West Babylon, Deer Park, and Lindenhurst.
- Upper floor is typically 60 to 75 percent of the main floor footprint
- Dormer additions can be included in the original design or added later
- Cost range: $190 to $270 per sq ft all-in
- Best for: smaller lots, buyers who want neighborhood curb-appeal consistency, phased finishing (rough-in upper floor now, finish later)
Two-Story
A full two-story puts equal square footage on both floors, maximizing living area on a compact footprint. This is the right move when your lot is narrow or when you need four or more bedrooms without spreading across a large slab. Two-story modulars also tend to be the most energy-efficient per square foot because the exterior envelope-to-floor-area ratio is lower.
- Typical size: 1,800 to 3,200 sq ft total
- Transport logistics: two-story modules ship as separate floor sections; crane time on-site is typically one full day
- Cost range: $185 to $265 per sq ft all-in
- Best for: growing families, lots under 7,500 sq ft, buyers prioritizing square footage per dollar

Raised Ranch
A raised ranch sets the main living floor several feet above grade, creating a lower level that is fully above ground on the rear or side of the home. On Long Island's gently sloping lots, this lower level can easily become finished living space — a family room, home office, in-law suite, or accessory dwelling unit — without the cost of a full walkout basement excavation.
- Lower level ceiling height is typically 8 to 9 feet, qualifying as living area
- Popular choice for multi-generational households
- Cost range: $195 to $275 per sq ft all-in (lower level finish adds to the base)
- Best for: sloped lots, multi-generational living, buyers who want flex space without a separate home addition down the road
Split Level
A split level staggers three or more floor levels, typically entry, a half-flight up to bedrooms, and a half-flight down to a lower family room or garage. This style handles grade changes naturally and was widely built across Long Island in the 1950s through 1970s, so a new modular split level slots visually into older neighborhoods without looking out of place.
- Efficient use of a lot with 3 to 6 feet of grade change front to back
- Entry foyer connects all levels with short stair runs rather than a full flight
- Cost range: $200 to $280 per sq ft all-in
- Best for: buyers replacing an older split level in-kind, lots with natural grade, households that want separation between living and sleeping areas
Chalet
The chalet style features a dramatic high-pitch roof with significant overhang, large windows on the gable ends, and an open loft above the main living area. While it is more common in Upstate New York and New England, it builds well as a modular and makes a strong visual statement on a wooded or waterfront lot. Suffolk County's South Shore and North Shore both have properties where a chalet-style home fits the landscape and the neighborhood character.
- Vaulted ceilings and loft area create a spacious feel at moderate square footage
- High window area benefits from quality insulated glazing — important for Long Island's mixed heating and cooling season
- Pairs well with a MRCOOL ductless mini-split system for efficient zone-by-zone climate control given the open floor plan
- Cost range: $210 to $290 per sq ft all-in
- Best for: waterfront or wooded lots, vacation-home-style primary residences, buyers who want a custom look
Long Island Permit and Zoning Notes
Regardless of style, new modular construction in Nassau and Suffolk counties requires a building permit, foundation inspection, set inspection (when modules are placed), and final certificate of occupancy. The permit process typically runs 6 to 14 weeks depending on the municipality and whether variances are needed for lot coverage or setbacks. We manage the full permit submission on your behalf as part of our design-build process and coordinate directly with local building departments across our Long Island service area.
