Prefab homes in New York: modular & ADU builders
Modular, ADU, and factory-built companies serving New York. Compare listings, then contact builders directly.
In this market
Searches for prefab homes in New York span very different projects: NYC-metro infill and ADUs, Hudson Valley primary homes, and upstate rural modular or manufactured installs. Prefably groups statewide factory-built companies so you can compare ratings and Prefably profiles before you travel to a plant or dealer lot.
Downstate buyers often prioritize panelized or compact modular solutions that fit tight lots and local design review. Upstate and western New York buyers more often compare full modular packages and manufactured homes for larger parcels. Energy code stringency and snow loads vary by region, ask for envelope details matched to your county, not a generic catalog sheet.
Every row on this page links to a Prefably company profile. Listings start as Unclaimed public records drawn from business data; builders can claim them free to update contact info and specialties. Prefer profiles with published ratings and a working website, then request a written factory-vs-site scope before you deposit.

FAQs
Prefab homes in New York
How many prefab and modular builders does Prefably list in New York?
As of 2026, Prefably lists 31 factory-built home companies associated with New York in this directory (claimed and unclaimed). Counts change as companies claim profiles or we add listings — use the cards on this page for the current shortlist, then contact builders directly.
Is modular construction legal in NYC?
Yes. New York City has approved modular for single-family and multifamily projects, including notable Brooklyn and Queens builds. DOB permitting is still complex compared with upstate towns.
Are ADUs legal in New York State?
There is no single statewide ADU mandate. NYC, Buffalo, Rochester, Ithaca, and other municipalities run local programs. Confirm the city or town before you order a factory ADU.
Modular vs manufactured in New York?
Modular on a permanent foundation is typically real-property / construction-to-perm lending. HUD-code manufactured homes use a different label and often a different loan product. Get the path in the contract.
What differs between upstate and downstate prefab?
Upstate projects often hinge on frost depth, septic, and winter set windows. Downstate and NYC projects add tighter lots, crane logistics, and heavier municipal review. Ask builders where they have actually set recently.
How do I find a local modular builder that delivers to my county in New York?
Use this directory to shortlist companies that advertise New York service, then ask each one to confirm haul routes, crane access, and set crews for your specific county, not just the nearest metro. Rural lots often need a site visit before a quote is real. Open Prefably profiles for ratings and websites, compare at least three written factory-vs-site scopes, and treat “statewide” marketing as a starting claim, not proof. Pair this page with our prefab-vs-modular and cost guides before you deposit.
