BACKYARD COTTAGE
This section outlines which city criteria your property meets or does not meet to determine your eligibility to build a backyard cottage (detached ADU).
This property does not meet the requirements.
We estimate you can build a backyard cottage of up to 523 square feet by right. With a special permit you may be able to build up to 1500 square feet. These are the criteria we checked:
Property Type:
Detached Single Family Residence
ADUs are allowed in Newton for detached (i.e. free standing) single family homes.
Lot Restrictions:
No Lot Specific Restrictions Identified
We did not identify historical or conservation restrictions on this property.
Building Capacity:
Building capacity of 523 sq ft, or up to 1,500 sq ft with a special permit
Newton sets FAR (Floor Area Ratio) limits for residential lots which dictate your lot’s capacity, or how much may be built. It’s not possible to definitively calculate your FAR without taking real-world measurements, so this is an estimate. We estimated your lot’s capacity based on available public records and used that to calculate how big of a backyard cottage you can build. The City Council may grant a special permit for up to 1,500 square feet. We estimated your habitable space; contact us if you’d like to learn more.

Please note, the backyard cottage needs to be in the back or side yard, at least 7.5’ from the lot line, and at least 5’ from the main house.
