Rental concentration, neighborhood by neighborhood

How this map works

This is the share of a neighborhood’s assessed residential parcels that the Franklin County Auditor flags as rentals. The denominator is residential parcels only (Auditor class 5xx), so commercial and vacant land don’t dilute it; the drawer shows what share of the neighborhood’s parcels that covers.

It’s a concentration measure, not a judgment — high rental share is simply where non-owner-occupied housing clusters, which is often where code-enforcement pressure and absentee ownership also show up. We use the Auditor’s own RENTAL flag rather than the homestead-exemption field, which in Ohio is age- and disability-gated and so isn’t a reliable owner-occupancy signal.

Source: Franklin County Auditor parcel data (city open data), refreshed on the parcel ingest. Neighborhood boundaries are the city’s area commissions, grown to cover the whole city — see methodology for boundary and suppression details. Neighborhoods with too few residential parcels show as “insufficient data” rather than a noisy number.
