ADU Rental Income by Neighborhood: Where's the Best ROI?

building an ADU is an investment. and like any investment, the returns depend on where you put your money. in NYC, ADU rental income varies dramatically by neighborhood — from $1,400/mo in parts of the bronx to $2,800+/mo in prime brooklyn.

but rental income alone doesn't tell the whole story. what matters is ROI — the relationship between what you earn and what you spend. a $2,500/mo rent sounds great, but not if it costs $300K to build. a $1,600/mo rent looks modest, but if it only costs $120K to build, that's a 16% annual return.

here are the top 10 NYC neighborhoods for ADU ROI, ranked by annual return on investment.

how we calculated ROI

for each neighborhood, we used:

• estimated build cost — based on median lot size, typical ADU type, and local construction costs
• estimated monthly rent — based on comparable rental listings for similar-sized units in the neighborhood
• gross annual ROI — (annual rent / build cost) × 100
• net annual ROI — factors in insurance (~$1,500/yr), maintenance (~$1,200/yr), vacancy allowance (5%), and property tax increase (after exemption period)

these are estimates, not guarantees. your actual numbers will depend on your specific lot, build choices, and the rental market at completion.

top 10 neighborhoods for ADU ROI

#1. pelham bay, bronx

metric	value
typical ADU type	basement conversion
build cost	$105K–$130K
monthly rent	$1,500–$1,800
annual gross income	$18,000–$21,600
gross annual ROI	15.4–17.1%
net annual ROI	12.8–14.5%
payback period	5.8–6.5 years

pelham bay takes the top spot because of the exceptional ratio between low build costs and solid rents. the 6 train access and Pelham Bay Park proximity support stable tenant demand. basement conversions are the sweet spot here — many homes have full-height basements ready for finishing.

#2. throgs neck, bronx

metric	value
typical ADU type	garage conversion / basement
build cost	$115K–$150K
monthly rent	$1,600–$2,000
annual gross income	$19,200–$24,000
gross annual ROI	14.4–16.7%
net annual ROI	11.8–14.0%
payback period	6.0–7.0 years

throgs neck's larger lots and strong community feel support both garage conversions and basement units. waterfront proximity pushes rents slightly higher than pelham bay. the neighborhood's stability means low vacancy rates.

#3. tottenville, staten island

metric	value
typical ADU type	detached cottage
build cost	$155K–$200K
monthly rent	$1,600–$2,000
annual gross income	$19,200–$24,000
gross annual ROI	12.0–12.4%
net annual ROI	9.5–10.2%
payback period	7.8–8.3 years

tottenville's large lots make detached cottages feasible, and the build costs are among the lowest in the city. rents are modest by NYC standards but the denominator (build cost) is low enough to generate strong returns.

#4. new dorp, staten island

metric	value
typical ADU type	detached cottage / basement
build cost	$140K–$200K
monthly rent	$1,600–$1,900
annual gross income	$19,200–$22,800
gross annual ROI	11.4–13.7%
net annual ROI	9.0–11.3%
payback period	7.3–8.8 years

new dorp's central location on the island and good transit access (SIR station) help with tenant demand. the mix of ADU types gives homeowners flexibility — basements for lower cost, cottages for higher rent.

#5. morris park, bronx

metric	value
typical ADU type	basement conversion
build cost	$100K–$140K
monthly rent	$1,400–$1,700
annual gross income	$16,800–$20,400
gross annual ROI	14.6–16.8%
net annual ROI	11.8–13.8%
payback period	6.0–7.1 years

morris park's smaller lots push most homeowners toward basement conversions, which happen to be the most cost-efficient ADU type. proximity to Einstein/Montefiore hospitals creates steady demand from healthcare workers — one of the most reliable tenant pools.

#6. east flatbush, brooklyn

metric	value
typical ADU type	basement conversion / detached
build cost	$130K–$200K
monthly rent	$1,700–$2,200
annual gross income	$20,400–$26,400
gross annual ROI	13.2–15.7%
net annual ROI	10.6–13.0%
payback period	6.4–7.6 years

east flatbush combines brooklyn rental premiums with build costs that are still below the borough's western neighborhoods. strong transit access (2/5 trains) and community stability support premium rents. this is arguably the best brooklyn neighborhood for ADU ROI.

#7. cambria heights, queens

metric	value
typical ADU type	detached cottage / basement
build cost	$150K–$220K
monthly rent	$1,800–$2,200
annual gross income	$21,600–$26,400
gross annual ROI	12.0–14.4%
net annual ROI	9.5–11.8%
payback period	7.0–8.4 years

cambria heights has some of the largest residential lots in queens, making it ideal for detached backyard cottages. the area's family-oriented character supports stable tenancies. JFK airport proximity creates demand from airport workers.

#8. great kills, staten island

metric	value
typical ADU type	detached cottage
build cost	$155K–$210K
monthly rent	$1,600–$2,000
annual gross income	$19,200–$24,000
gross annual ROI	11.4–12.4%
net annual ROI	8.9–10.0%
payback period	8.1–8.8 years

great kills benefits from SIR access and a strong neighborhood commercial corridor. build costs are typical for staten island (favorable), and rents are solid for the borough.

#9. bayside, queens

metric	value
typical ADU type	basement / garage conversion
build cost	$140K–$200K
monthly rent	$1,800–$2,300
annual gross income	$21,600–$27,600
gross annual ROI	13.8–15.4%
net annual ROI	11.0–12.8%
payback period	6.5–7.3 years

bayside commands premium rents thanks to excellent schools, low crime, and strong transit (LIRR + express buses). the higher build costs are offset by rents that push toward the top of the ADU range. basement and garage conversions are the smart play here — the lots support them and the cost efficiency is better than detached construction.

#10. canarsie, brooklyn

metric	value
typical ADU type	basement conversion / detached
build cost	$130K–$210K
monthly rent	$1,700–$2,100
annual gross income	$20,400–$25,200
gross annual ROI	12.0–15.7%
net annual ROI	9.5–12.8%
payback period	6.4–8.4 years

canarsie rounds out the top 10 with a similar profile to east flatbush — brooklyn rental premiums with below-average brooklyn build costs. the L train connection to manhattan keeps demand strong, and the neighborhood's residential character is ideal for ADU tenants who want a quieter setting.

the ROI pattern

looking across all 10 neighborhoods, the pattern is clear:

• highest percentage ROI comes from the bronx and eastern brooklyn — where build costs are lowest relative to rents
• highest absolute rental income comes from queens and western brooklyn — but higher build costs reduce the percentage return
• staten island offers a middle ground — moderate rents with the lowest build costs in the city
• basement conversions have the best ROI across all boroughs because build costs are lowest ($100K–$140K range)
• detached cottages command higher rents but cost more — the ROI is typically 2–3 percentage points lower than conversions

factors beyond ROI

ROI is the most important metric, but it's not the only one. also consider:

• tenant quality and stability — neighborhoods with strong community character tend to attract long-term tenants, reducing turnover costs
• appreciation trajectory — areas with rising property values mean your ADU investment appreciates alongside the property. the bronx and eastern brooklyn are appreciating faster than SI.
• your own residence — if you already live in the neighborhood, the convenience factor is significant. managing a tenant in your own backyard is much easier than managing from across the city.
• construction logistics — some neighborhoods are easier to build in than others. narrow streets, limited parking, and dense housing stock add time and cost.
