Summary
Blue Hill's Article Four Use Regulation Matrix allows an accessory dwelling unit as a permitted use in the Residential (R) and Downtown Mixed Commercial Use (DT) districts, but marks it prohibited with a dash in the Agricultural (AG), General Commercial (GC) and Light Industrial (LI) districts, so an ADU can be added by right only on R or DT zoned property.

Full Breakdown
The City of Blue Hill Zoning Ordinance's Article Four Use Regulation Matrix lists Accessory dwelling units as a distinct residential use alongside single-family dwellings, duplexes, and townhouses, and assigns it a permission letter in each of the City's five zoning districts: Agricultural (AG), Residential (R), General Commercial (GC), Downtown Mixed Commercial Use (DT), and Light Industrial (LI). The row reads a dash for AG, P for R, a dash for GC, P for DT, and a dash for LI, meaning an accessory dwelling unit is a permitted, by-right use only in the Residential and Downtown Mixed Commercial Use districts and is prohibited outright everywhere else in the city.
6. An accessory dwelling still has to satisfy the underlying zoning district's own dimensional standards, such as the Residential district's 7,000-square-foot minimum lot size, 10-foot interior side setback, and fifty percent maximum lot coverage, since the use table only governs whether the use is allowed, not the bulk standards that apply once it is.
Violations & Fines
Building or occupying an accessory dwelling unit in the Agricultural, General Commercial or Light Industrial district, where the use table marks it prohibited, is a zoning violation. Section 9.8 makes any such violation a misdemeanor punishable by a fine of up to $100 per offense, with each day the noncompliance continues treated as a separate offense.
