The best ADU type depends on your lot size, existing structures, and budget. Here are the most viable options for Eltingville homeowners.
Eltingville's large lots (3,500–5,000 sq ft) and suburban layout make detached backyard cottages the most natural ADU type. Wide rear yards with alley access simplify construction logistics.
Oversized detached garages are widespread in Eltingville. A 2-car garage conversion into a studio or 1-bedroom ADU is a popular, budget-friendly option that reuses existing structure and foundation.
Many Eltingville homes have full basements with walk-out potential on sloped lots. These conversions are the quickest and most affordable ADU path, often completing in under 6 months.
Construction costs vary by ADU type, size, site conditions, and finishes. These ranges reflect typical Eltingville projects.
| ADU Type | Estimated Cost | Timeline |
|---|---|---|
| Basement Conversion | $90,000–$195,000 | 3–6 months |
| Garage Conversion | $130,000–$255,000 | 4–7 months |
| Detached Backyard ADU | $200,000–$390,000 | 6–12 months |
