What is a recorded map?

Subdivision maps

• Show land divided into many lots
• May be referenced in a property’s legal description, within a deed, often with a lot and block number
• Use "RM" with a Book and Page, or Year and Page, to identify the map, like when requesting copies

Parcel maps

• Show land divided into a few lots
• May be referenced in a property’s legal description, within a deed, often with a lot and block number
• Use "PM" with a Book and Page, or Year and Page, to identify the map, like when requesting copies
• Note: Recorded Parcel Maps are not the same as an Assessor Parcel Map, or AP Map. AP Maps, are created for assessment purposes only and are available online using a parcel number.  

Survey maps

• Show a survey of one or more parcels of land
• Not all surveys are recorded
• Some Assessor Parcel Maps show bold corners around a parcel with a reference number that points to a recorded survey
• You can also search the Recorder’s Index using the term SURVEY and the owner's last name (for example, SURVEY SMITH)
  • Note: The index will have a reference to a marker page, which includes the Book and Page of the map
  • The marker page does not include an image of the survey map
• Use "OS" or "RS" with a Book and Page, or Year and Page, to identify the map, like when requesting copies
