What affects the price

Building an ADU is a custom project, so costs vary based on your specific choices. Site conditions are the biggest factor; if your land requires significant grading, utility extensions, or foundation work, those expenses add up quickly. Choosing high-end finishes, custom cabinetry, or complex roof lines will also push the budget higher compared to a standard design. Prefabricated units often offer predictable costs, while custom site-built structures allow for more flexibility but can be harder to estimate upfront. Exact pricing confirmed free on the call.

How much does an ADU cost in New York?

What are the rules for ADUs in New York?

New York City has specific zoning laws and building codes that dictate ADU construction, especially regarding occupancy and size limitations. Understanding these rules is crucial before starting any project. The Department of Buildings oversees these regulations. A local expert can clarify what's permissible for your property.
