The best ADU type depends on your lot size, existing structures, and budget. Here are the most viable options for Sheepshead Bay homeowners.
Sheepshead Bay's mix of detached and semi-detached homes frequently feature full basements with walkout potential, especially on homes near the waterfront. Many have existing separate entrances making conversion efficient.
Properties in southern Sheepshead Bay tend to have deeper lots than Brooklyn's average, providing space for a detached backyard ADU. Lots over 2,500 sq ft are particularly well-suited.
Detached garages are widespread in the area. Converting an existing garage into a living unit avoids the higher costs and longer timelines of new construction while adding valuable rental income.
Construction costs vary by ADU type, size, site conditions, and finishes. These ranges reflect typical Sheepshead Bay projects.
| ADU Type | Estimated Cost | Timeline |
|---|---|---|
| Basement Conversion | $120,000–$245,000 | 3–6 months |
| Garage Conversion | $170,000–$295,000 | 4–7 months |
