Boston FAQ
Chelsea FAQ
Do I need a permit for a kiddie pool in Boston?
No — pools with less than 24 inches of water depth are exempt from 780 CMR permit requirements. But larger inflatable or temporary pools exceeding 24 inches do require permits and barrier compliance.
How close can my Boston pool be to the property line?
Boston Zoning Code setbacks apply — typically 10+ feet for accessory structures, but the Conservation Commission may require additional buffers if wetlands are within 100 feet (MGL c. 131 §40).
