Find Property Records and Parcel Maps in Montgomery County

This page helps users handle a Montgomery County, Maryland property search using official real property and mapping resources. It points you to the main tools for finding assessment records, parcel details, property layers, and map-based information.

For statewide real property records, use the Maryland Department of Assessments and Taxation Real Property Data Search. For Montgomery County parcel maps and local GIS layers, use MCATLAS from Montgomery County Planning.

SDAT Real Property Data Search

The Maryland Department of Assessments and Taxation provides the main real property database for Maryland assessment records. Use the SDAT Real Property Data Search to select Montgomery County and search for a property record.

You can search by several property identifiers, but owner-name searching is not available.

• Street address
• Street name
• Property Account Identifier
• Map reference

Address searches work best when you leave off street directions and street suffixes. For example, do not include words such as North, West, Street, Avenue, Drive, or Way unless the system requires a different format for that record.

• Select Montgomery County from the county menu.
• Choose the search method that matches the information you have.
• Enter the address, account identifier, or map reference.
• Open the matching property record and review the assessment details.

Maintenance note: the Real Property Search page may be unavailable before 7:00 AM.

Search limits and record accuracy

SDAT real property data is provided for information purposes. It is not for legal reports or legal documents, and the department does not make warranties about the information.

The SDAT system cannot be searched by owner name, town, neighborhood, subdivision, or ZIP code. Deleted accounts can only be searched by Property Account Identifier.

The SDAT website terms prohibit automatic or robotic data collection, extraction, copying, data mining, and web scraping.

Address and account identifier tips

If an address search does not find the right property, try a broader street-name search. You can also truncate a street name with an asterisk to return similar street names.

For a Property Account Identification Number, use the number shown on the assessment notice. Montgomery County’s county code is 16. The letters after the Property Account Identification Number are for internal use and are not part of the number.

If property information is incorrect or you have assessment questions, contact the appropriate local assessment office. SDAT does not provide copies of tax bills on its website.

MCATLAS parcel maps and local GIS layers

MCATLAS is Montgomery County Planning’s main map viewer. It includes property parcels, property points, zoning, boundaries, planning areas, record plats, development review layers, environmental layers, transportation layers, school boundaries, parks information, and aerial imagery.

MCATLAS can help when you need to view a property on a map, compare nearby layers, or check parcel context that may not be clear from a text-only assessment record.

Map data is provided for public use, but Montgomery County Planning disclaims warranties and liability for use of the data.

GIS data downloads and property layers

Montgomery County Planning maintains the county property layer and related planimetric data. The county also provides GIS datasets and map applications for public use.

Use the Montgomery Planning GIS and Mapping page for MCATLAS, interactive maps, data downloads, CAD property data, elevation data, impervious data, tree canopy data, and zoning resources.

For broader county GIS datasets, the Montgomery County GIS Open Data site provides public GIS data, tools, and map applications.

Deeds, plats, and tax bills

SDAT real property search results do not provide deeds, plats, property tax bills, or payment records. Deeds and plats are handled through Maryland land records and plat resources, while tax billing questions go to the appropriate county or municipal government.

For basic assessment and property lookup help, use SDAT first. For parcel mapping and local layers, use MCATLAS. For tax bill or payment questions, contact the local tax billing and collection office.
