Should I consider a prefabricated ADU?

If you are considering building a freestanding ADU, then exploring your options, getting quotes and comparing them with stick-built ADU quotes is a key component of your decision-making. 

Considering if you will pour a slab for the foundation or if your stand-alone ADU will have another sort of foundation is also another key piece of decision making. 

Here are a number of companies located in New England that offer prefab ADUs:

Many of these companies offer super insulated ADUs that can easily meet the Stretch Code in Massachusetts. They can be ready for solar and some offer heat pumps for space heating and include a heat pump hot water heater, for fossil free operation.
