Special needs house?

[Thomas Hickey]

Hi All, I'm researching buying a large 4-5 bedroom house in the suburbs of Boston and converting to light special needs housing. A few questions? -does the property need to be zoned commercial? - does the town need to approve of my plan? Or does the fact that it is special needs override local town? Kind of like 40B - would I need to add sprinklers, fire control panel and hard wired smokes for said property? - what government agency would I contact to see how much I would be paid through vouchers? Trying to see if it makes sense, thanks for any input Bill Gulley Tom
