If you did have to add something, each individual property depending on town, location of existing structures, lot size, etc would have different requirement as far as what you could add.
Please let me know if I can be of assistance in any way.

Anyhow- each town does have their own bylaws, but there is a standard Mass. State building code that pertains at a minimum.
Usually, if an outbuilding is greater than 120 sf (floor area), then you would need a building permit. In some towns you may not be able to build a 10x12 or larger "shed" within the typical side and rear property line setbacks.
You need to check the setback requirements and also just call and speak with the town's building dept. There is no concrete answer here.
If you need any further help, just let me know. Thanks and good luck,
There might be some homes available for sale that already have a suitable outbuilding. How large of studio do you want? Contact me through my profile and I would be glad to search for you. Good luck!
