Prefab adu — New York, NY
Last updated: September 24, 2026
What affects the price
Building an ADU involves variables that shift your total investment. The footprint size and complexity of the architectural design are primary factors. Are you planning a detached unit that requires new utility trenching, or is this a garage conversion that uses existing plumbing? Site accessibility, soil conditions, and your choice of finishes—like luxury flooring versus standard options—also play significant roles. Permitting fees vary widely depending on your local municipality and current zoning requirements. Exact pricing confirmed free on the call.
About this service
A prefab ADU is built in a factory environment and then transported to your property. This method is often faster than traditional site-built homes because the construction happens off-site while your foundation is being prepared. It is a great choice if you want to minimize construction noise and mess in your backyard. Prices typically vary based on transportation distances and crane requirements. Exact pricing confirmed free on the call.
