The best ADU type depends on your lot size, existing structures, and budget. Here are the most viable options for Great Kills homeowners.
Great Kills' spacious lots provide excellent opportunities for detached backyard ADUs. The neighborhood's suburban character means most properties have ample rear yard space and good access for construction.
Large detached garages are common throughout Great Kills. Converting a garage is a cost-effective option that avoids new construction while adding a complete living unit to your property.
Many Great Kills homes feature full basements with walk-out access. However, properties near the waterfront should be assessed for flood zone requirements before pursuing a basement conversion.
