Common questions
How many parcels are in Frederick County, Maryland?
JB PARCEL carries 110,838 parcel records for Frederick County, Maryland, with owner information on 3 percent of them.
Can I find out who owns a property in Frederick County?
Not from us for Frederick County yet. We carry 110,838 Frederick County parcels with lot lines and location, but the county's published file carries owner names on fewer than 5 percent of parcels, so owner search finds few records here. Owner search works in the counties where we hold the field, and Frederick County does carry assessed values, recorded sales and year built.
How do I find vacant land or absentee owners in Frederick County?
We do not hold vacancy data for Frederick County yet, so this filter has nothing to match there. Vacancy filters work in the counties where we hold the field. Frederick County does have owner mailing state: 178 parcels have an owner mailing address outside Maryland.
Can I search Frederick County by lot size or acreage?
Yes. Acreage is on 98 percent of Frederick County parcels, mapped from the parcel boundary, and the advanced search filters on it directly - set a minimum and maximum to pull every tract in that range, then stack vacancy or absentee ownership on top.
