The best ADU type depends on your lot size, existing structures, and budget. Here are the most viable options for Bay Ridge homeowners.
Bay Ridge's well-maintained brick rowhouses and semi-detached homes feature deep basements with good ceiling heights. Many have existing side or rear entrances suitable for ADU access. This is the most cost-effective option in the neighborhood.
Detached garages accessed via rear alleys are common in Bay Ridge. Converting these into a studio or 1-bedroom unit is a popular mid-range option that avoids extensive new construction.
Larger corner lots and wider properties in Bay Ridge can support a compact detached ADU. The neighborhood's stable property values make the higher investment in new construction worthwhile.
Construction costs vary by ADU type, size, site conditions, and finishes. These ranges reflect typical Bay Ridge projects.
| ADU Type | Estimated Cost | Timeline |
|---|---|---|
| Basement Conversion | $130,000–$260,000 | 3–6 months |
| Garage Conversion | $175,000–$310,000 | 4–7 months |
| Detached Backyard ADU | $260,000–$480,000 | 6–12 months |
