I'm not sure about Boston proper but I have a friend on the Cape who has a little cottage industry working with RE agents that have to permit / bring up to code existing renovations that were never permitted. 

From what we've seen pricing software pays for itself within a single night.If you are concerned about the cost though I do have a discount code for Price Labs on our website home-havens.com that will get you a little better deal.

Also they require a specific business license, inspection, and additional code requirements for STRs.

First, about me, I am a commercial code consultant.

What zip codes within Mecklenburg County (Charlotte) do you recommend targeting when looking for rental properties (single family homes, duplexes, triplexes, and 4-units)?

@Rachel Luoto  What zip code is the property located in?

The ones I know of so far are (please correct if wrong):5% TaxOption for the city to inspect for code complianceOption for city to inspect for food and safety complianceSomeone associated with the property must live within 50 miles of rental

Zip code : 44128Wondering if I should buy property here ?

What zip codes are you interested in?

I am new here so I don't have much advice to offer other than to pick an area and call the zoning board or code inspector for that area.
