A truck carrying several enormous sections arrives at an empty foundation. Within hours, cranes begin lifting bedrooms, kitchens and roof sections into position. What looked like an open construction site in the morning can resemble a real house before sunset.
Modern modular homes are permanent buildings constructed in factory-controlled conditions and assembled on prepared foundations. They must meet the applicable state and local building codes, just like comparable site-built houses. However, the final cost depends heavily on land preparation, foundation work, transport, utility connections and on-site finishing.
For New York buyers, the strongest choices include both turnkey builders and manufacturers working through approved local contractors. Here are our top modular home company picks for 2026.
1. Westchester Modular Homes
Westchester Modular Homes is one of New York’s most established custom modular manufacturers. The company is headquartered in Wingdale and works with independent builders throughout New York and several other northeastern states.
Its residential options include ranches, raised ranches, Colonials, Craftsman homes, Capes, chalets, vacation houses, multifamily buildings, carriage homes and accessory dwelling units. Buyers can modify existing plans or work with the company and their architect on a completely original layout.
Westchester constructs the main modules in its climate-controlled factory while the foundation is being prepared at the property. This parallel process can reduce weather-related delays. The company also offers virtual and in-person factory tours, allowing buyers to inspect how its homes are produced before selecting a builder.
Why Westchester Modular Homes is included: Its New York manufacturing facility, broad design range and experience with fully customised projects make it one of the strongest options for buyers across the state.

Ritz-Craft is a large family-owned modular manufacturer operating through approved independent builders. Its Northeast Division in Pennsylvania supplies residential projects across the region.

Available styles include ranches, Capes, two-storey homes, lake houses, coastal designs and multifamily properties.
Ritz-Craft states that its factory and site work can proceed at the same time, with some projects reaching completion in approximately five to six months. However, the real schedule depends on permits, land conditions, builder availability and the complexity of the design.

What Should Buyers Compare?
Ask every company for an itemised quotation showing what is included. A low factory price may exclude excavation, foundation work, transport, crane hire, permits, utilities, septic installation, garages, porches and final interior work.
Confirm whether the company is providing a complete turnkey home or only manufacturing the modules. Buyers should also review the structural warranty, completion schedule, payment stages and responsibility for damage during delivery and installation.
Frequently Asked Questions
Q: Can a modular home be built on any plot in New York?
A: Not automatically. The land must comply with local zoning, setback, access and environmental rules. The site must also allow delivery trucks and a crane to reach the foundation safely.
Q: Can a modular home include a basement?
A: Yes. Modular homes can be installed over full basements, crawl spaces or approved slab foundations. The foundation is normally constructed on-site before the modules arrive.
Q: Are modular homes difficult to finance?
A: They can be financed through construction loans and standard mortgages, but the lender must understand modular construction. Buyers should confirm how the bank releases payments to the factory and on-site builder.
Q: Can buyers change a modular floor plan?
A: Most companies allow changes to room sizes, kitchens, bathrooms, windows and exterior finishes. Major structural changes may require a fully custom design and additional engineering.
Q: Who is responsible for completing the house after delivery?
A: That depends on the contract. A turnkey builder manages the project through completion, while a manufacturer may only produce and deliver the modules. The buyer must confirm who handles the foundation, crane, plumbing connections, electrical work, inspections and final certificate of occupancy.
