New York City is offering homeowners up to $395,000 to build accessory dwelling units (ADUs) on their property. This program, part of the city’s push to create more housing, pays homeowners to convert basements, garages, or backyard spaces into legal rental apartments. For homeowners in Staten Island and Brooklyn, this represents a rare opportunity to generate rental income while building equity. Joseph Ranola explains how the program works and who should consider it.
How the ADU Program Works
The NYC Department of Housing Preservation and Development (HPD) launched a program that provides forgivable loans of up to $395,000 to homeowners who build new ADUs or convert existing spaces into legal rental units. The funds cover construction costs, architectural plans, and permitting. In exchange, homeowners agree to rent the unit at affordable rates for a set period, typically 15 years. After that period, the loan is forgiven and the homeowner has a fully legal rental unit that can generate market-rate income indefinitely. The program prioritizes owner-occupied one- to three-family homes in neighborhoods where housing demand is highest.
Why Staten Island and Brooklyn Homeowners Are Ideal Candidates
Both boroughs have large concentrations of single-family homes with basements, detached garages, and backyards that could accommodate ADUs. Many Staten Island homes already have finished basements that would require minimal conversion to meet building code. Brooklyn’s lot sizes, while smaller, can often support backyard cottages or garage conversions. The rental demand in both boroughs is strong, meaning homeowners can expect consistent occupancy and competitive rents. For a homeowner with an unused basement, the program essentially pays for a renovation that creates a permanent income stream.
The Financial Case for Building an ADU
Even with the affordable rent requirement during the compliance period, an ADU generates significant income. A legal basement apartment in Staten Island might rent for $1,200 to $1,800 per month at affordable rates, generating $14,400 to $21,600 per year. Over the 15-year compliance period, that is $216,000 to $324,000 in rental income from an asset that cost you nothing to build. After the compliance period, you can charge market rents, which could be significantly higher. The ADU also increases your property value, as a legal rental unit is a premium feature for future buyers.
The Application Process and Requirements
Applicants must own and occupy a one- to three-family home in New York City. The property must have sufficient space for a code-compliant ADU. Homeowners must work with HPD-approved architects and contractors. The process includes an initial eligibility screening, architectural review, permitting, construction, and a final inspection. The timeline from application to completed unit is typically 12 to 18 months. While the process involves bureaucratic steps, HPD provides support throughout, and the financial benefit is substantial enough to justify the effort.
Should You Build an ADU
If you own a single-family home in Staten Island or Brooklyn with a convertible basement, an underused garage, or sufficient backyard space, this program deserves serious consideration. The government is offering to pay for a renovation that creates a permanent income-generating asset on your property. Joseph Ranola advises homeowners to evaluate not just the immediate rental income but the long-term value impact. A legal ADU can add 10-20% to your property value, making this one of the most financially compelling programs the city has offered homeowners in years.
