Hi Harry

Great last question. Our Counsel opined that only one Protected Use ADU per legal lot can be established, so if the condo was on one lot and had 20 units, only one ADU would be permitted. Of course, the Condo R&Rs would need some level of specificity (likely lacking now) that would facilitate how that could be done. They also deemed the “primary dwelling” to be the largest of the buildings on the lot. I am not sure of that rationale, but hopefully we keep this analysis and discussion going.

Best,

Chris R.

Is it Friday already?

There is a mention in the final regs (CMR 71.03 (2) (d)) under Prohibited Regulations, that Protected Use ADU's can't count in density calculations.

(d) Unit Caps & Density. Any limit, quota or other restriction on the number of Protected
Use ADUs that may be permitted, constructed, or leased within a Municipality or Zoning
District. Protected Use ADUs shall not be counted in any density calculations.

So, do ADU's only count when one is not using the number for a density calculation? ("Density Calculations" is not defined in 71.02...)

Perhaps EOHLC will someday clarify... I'm still wondering if every condo in a multi condo development can have their very own ADU.

Good afternoon,

I believe an ADU will count towards our total dwelling unit count. Is that correct?

Thanks.
