ADU Regulations in Dracut

This means all Massachusetts state-level ADU rights apply — including by-right approval, no owner occupancy requirement, and standardized size limits. Dracut may also have additional local regulations that supplement the state baseline.

Size Limits: Room for a Full Cottage

At 900 sq ft, Dracut allows enough space for a complete 2-bedroom accessory dwelling unit. This is well above the minimum needed for a comfortable living space and provides flexibility for a kitchen, bathroom, living area, and dedicated bedrooms.

Percentage-Based Size Limit
