You can find out if your property is located within the Historic District by searching for your property on MapGeo. Type in your address in the “Property Quick Search” box in the upper right corner of the map. Click on the “Themes” layer and toggle on “Zoning”. The legend will indicate which zone or zones your property is located in.  

A property is in the Historic District if: 

1. There is a red outline around the perimeter of the entire property; or

2. If the red boundary line bisects any part of any structure of the property. 

If your property lies within the Historic District or if you have a questions as to whether your property is in the historic district, please reach out to Izak Gilbo, HDC Staff Planner/Liaison at igilbo@cityofportmsouth.com or (603)-610-7235 to discuss your project and for guidance on the permitting process. 

A Land Use Permit Application is required for projects that require land use review by Planning Department staff and those that involve new construction, an addition or expansion of an existing building, home occupations, or any exterior renovations of properties located in the Historic District, as well as for any projects that require approval from the City's land use boards (Planning Board, Historic District Commission, and Zoning Board of Adjustment) including subdivisions, site plan review, conditional use permits, variances, special exceptions, and historic district commission certificates of approval. Please click here for more information on land use applications, forms and fees. For Building Permit requirements see the Inspection Department FAQs.

You can find your Zoning District by searching for your property on MapGeo. Type in your address in the “Property Quick Search” box in the upper right corner of the map. Click on the “Themes” layer and toggle on “Zoning”. The legend will indicate which zone or zones your property is located in.  

The Zoning Ordinance outlines the use requirements for each zoning district in Section 10.440 - Table of Uses and the dimensional requirements in Article 5 and Section 10.521 - Table of Dimensional Requirements.  

If you need more assistance with the specific zoning requirements for your project please inquire with the Planning and Sustainability Department staff at (603) 610-7216.
