Finding a Tax Map Using an Address:
Open the “Lookup by Location” document, find your property address. Once you find your address, you’ll find the property’s Map,Lot(also known as “Parcel ID) and Page number. For example, Somersworth City Hall is located at 1 Government Way with a Map number of 11, a Lot number of 212 and a page of F5 (Parcel ID 11 212 on page F5).
From the list of pages, click on F5. Once that page is open, look for the property with a Parcel ID of 11 212.
Finding a Tax Map Using the Property Map Index:
Open the Property Map Index. The Property Map Index is a map of the entire City. You can open this map and find a location that you want to see with more detail. Once you find that location on the Property Map Index, notice the number that corresponds with that row to the left and the letter that corresponds with that column on the top. That letter/number combination is the Page number you want to look for.
The Geographic Information Systems data issued by the City is for planning purposes only. Property information shown in the parcel maps was compiled from the existing Assessor’s tax maps maintained by the Department of Development Services. Parcel boundary data was NOT compiled through property research and recompilation. The City assumes no legal responsibility for the information shown on these maps. The tax maps were last printed in 2009.
