Aging housing stock by neighborhood
Where is Columbus’s oldest housing — and the pre-1978 lead-paint risk that comes with it? Search your address to see how your area compares, or click any neighborhood on the map. Switch between the median age of homes and the share built before 1978.
How to read this map
Median age is the middle age of a neighborhood’s homes, computed from the Franklin County Auditor’s year-built field. Older neighborhoods read hotter. We show an age rather than a build year so the color runs the intuitive way — hotter means older — and the drawer carries the underlying median year built and the number of homes behind it.
Pre-1978 share is the share of homes built before 1978, the year lead-based paint was banned for residential use. It’s the sharper public-health read: older stock is far more likely to carry lead paint and to need remediation before children live in it. Both views count assessed residential parcels that carry a build year; the drawer shows what share of a neighborhood’s homes that covers.
Source: Franklin County Auditor parcel data (city open data), refreshed on the parcel ingest. Only Columbus neighborhoods are shown; the Auditor file is county-wide, so suburban parcels are excluded from the canvas. 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 homes carrying a build year show as “insufficient data” rather than a noisy value.
