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).

We estimate you can build a backyard cottage of up to 8 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:

This property does not meet the requirements.

Property Type:

Detached Single Family Residence

ADUs are allowed in Newton for detached (i.e. free standing) single family homes.

MAYBE ICON.png

Lot Restrictions:

Historic Restrictions Found

We identified a historic restriction on this property, which warrants further investigation. Preservation restrictions don’t automatically disqualify a property. However, further review and approvals may be required.

MAYBE ICON.png

Building Capacity:

Building capacity of 8 sq ft is not enough for a backyard cottage

Newton sets FAR (Floor Area Ratio) limits for residential lots which dictates your lot’s capacity, or how much may be built. It’s not possible to definitively calculate your capacity without taking real-world measurements, so this is an estimate. We estimate that your lot does not have sufficient capacity to build new structures. We estimated your habitable space; contact us if you’d like to learn more.

Do you have an historic carriage house on your property? If so, you are eligible to convert that to an ADU. Contact us to find out more.

See Where a Cottage Might Fit

Select a footprint size and drag it around the map! 

 

Here are a few common sizes to get you started. This is just the footprint—you can have a loft or half story for more space. One of our vetted partners can help design the perfect space for you!

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.
