Under the tab for each county is a link for the county government's website, if they have one. For each city or town that has Municipal Ordinances published on its website, there is a link to their ordinance page. Some towns only provide for contact information to acquire ordinances. The guide will also provide a link to the list of municipalities for that county that is provided either by the county government's website or the state government's website as well as a link to the county Registry of Deeds.
