The Aquinnah MA parcel bounds and related Assess table were compiled by Cartographic Associates in FY19 and forwarded to MassGIS for final processing into the Commonwealth's Level 3 Parcel Data Standard. The related table of building information was provided to the Martha's Vineyard Commission from the Town's assessing department in the year 2020. All related tables join to the feature class based on [Loc_ID].

The complete minimum parcel size table for all types of Use within all Zoning Districts on Martha's Vineyard is available here.Click here for details about the zoning districts.

Overlay zoning districts are in addition to standard town zoning. The districts' boundaries and use limitations &/or development constraints are described in the town's zoning bylaw. The MVC generated these digital spatial boundaries based on the best GIS data available at the time of processing.

Some overlay zoning districts are also Districts of Critical Planning Concern. These are zoning districts established by the Martha's Vineyard Commission and adopted by the town at town meeting.

The boundaries are not survey-grade and are intended for planning purposes only.

This website is provided by the Town of Aquinnah. The information is updated periodically by the town assessor. The public may search for parcel boundaries and view all the associated assessing data for that parcel. The MVC does not maintain this parcel look-up website.

MassGIS Level 3 Parcel Data: Data Fiscal Year: Aquinnah 2019, Chilmark 2020, Edgartown 2021, Gosnold 2015, Oak Bluffs 2021, Tisbury 2021, West Tisbury 2021.Building Info Table: Acquired by MVC from Town Assessors in FY20.Downloaded from MassGIS,, this polygon file represents the parcel bounds for the 7 towns in Dukes County MA (Aquinnah, Chilmark, Edgartown, Godnold, Oak Bluffs, Tisbury, West Tisbury). Each town has their own parcel data consultant and then the data are forwarded to MassGIS for final processing. All data comply with the MassGIS Level 3 Parcel Data Standard. This file geodatabase only includes the TaxPar feature class and Assess table for each town. All TaxPar feature classes were appended into one feature class (Parcels_duk) by the MVC.Each assess table is utilized in that town's respective relationship join (1 to Many) for linking the parcel polygon to the related record(s) in the Assess table. The Assess Table contains info about ownership and assessed values. This is not a detailed building table. If there are multiple owners associated with a property, then the Assess table will have multiple records for that property/parcel (such as for condo parcels).Each building table is utilized in that town's respective relationship join (1 to Many) for linking the parcel polygon to the related record(s) in the Bldg table. The Bldg (building) table contains info about each building on the parcel (such as number of bedrooms, number of bathrooms, the living area square footage, etc.). NOTES of CAUTION: The Living Area Square Footage may not represent the exact same thing in each town. As a generalization, Living Area is interior space that is heated. Regarding West Tisbury, their building table only contains info for one building on the parcel. It is uncertain at this time if the info is the most recent, most primary, or some kind of summarization where multiple buildings on a parcel exist.The field of [assess_mYB] represents the Minimum/Earliest Year Built for any building on the parcel and is appended to the TaxPar feature class based on an analysis of the info provided in the building table. This field [assess_mYB] is utilized in the Historic Structures App found in ArcGIS OnLine.

Prior to upload to the AGOL cloud, the Martha's Vineyard Commission set a definition query to only include those parcels having an Assessor's Use Code of either 6*, 7*, or 8*.The parcel boundaries and info are the most recent available per MassGIS as of June 2019. For the most current assessing info, please contact the Town's Assessing Office.The parcel boundaries and attribute table conform to the State's Level 3 Parcel Data Standard. See MassGIS for full details.See the MA Property Types Classification Code for a full explanation of each code.
