ATTOM’s Neighborhood and Residential Subdivisions for Hyperlocal Search

ATTOM’s Neighborhood and Residential Subdivisions Boundaries data provides a nationwide, hierarchical set of boundaries and names that best reflect the consensus opinion of local residents.

Neighborhood and Residential Subdivisions are small geographic areas comprised of social communities with their own identities, while also having names and boundaries that are familiar to local residents. This makes them the pinnacle of hyperlocal search and superior to zip codes or cities for most use cases. Research has shown that consumers strongly prefer hyperlocal search capabilities. Savvy search portal operators incorporate these boundaries datasets into their platforms.

Meticulously Researched and Digitized

Created specifically for real estate search, our research includes official city and county maps, local tourism and media websites, community master plans, MLS & Realtor websites, HOA websites, developer site plans, assessor legal subdivision data, and satellite imagery. Our GIS Analysts also virtually drive through entire cities in Google Street View to review subdivision and condo signage. Feedback is also provided by local experts from our nationwide network of real estate professionals.

Our GIS Analysts hand-digitize these neighborhood and residential subdivision boundaries, tracing reference layers such as streets, parcel boundaries, and hydrography.

Nationwide coverage is available in the U.S. and Canada and includes hundreds of thousands of boundaries in over 600 metro areas and 10,000 cities and towns.

Neighborhood Hierarchy Supports Many Use Cases

Level 2: Neighborhoods

Level 3: Sub-Neighborhoods

Sub-Neighborhoods are smaller, named areas usually found in the core of a city within a larger Level 2 Neighborhood. They are often business, entertainment, arts, or historic districts.

Level 4: Residential Subdivisions
