How to Look Up Building Permits in Louisville
Every building permit filed in Louisville, KY is public record, maintained by Louisville Metro's Develop Louisville / Planning & Design Services. Here's how to pull the full history for any address — and the shortcut when you'd rather not do it by hand.
Why you'd want the permit history
- Buying a home: confirm that additions, remodels, and major repairs were permitted and finaled.
- Selling or refinancing: unpermitted work surfaces in inspections and appraisals — know before the buyer does.
- Insurance and disputes: a dated permit record is the evidence that work was done to code.
- Finding the contractor: Louisville names the licensed contractor on some permits but not all — where it did, the name is on the record.
Step by step, using the city's own tools
- Louisville Metro publishes its permit records as open data rather than behind a search form: the metro's ArcGIS open data hub (louisville-metro-opendata-lojic.hub.arcgis.com) and data.louisvilleky.gov carry the same tables, and that is what PingPermit reads.
- There are two permit tables and they cover different eras. The active construction permits layer holds 22,902 rows issued from February 2014 onward and is the live one. A second table, published as the historical record, holds 437,035 rows — and it stops: its newest row is dated 14 June 2019 and its oldest 4 November 2003. Between them the two cover 2003 to today, with an overlap rather than a join.
- Each permit carries the permit number, permit type, status, work type and category, zoning, square feet, the permit fee, the declared project cost, the address, the city, the ZIP, the council district and the neighbourhood.
- Louisville records an ISSUE date and no application date, so a permit that has been applied for and not yet issued does not appear in the public table at all.
Things that trip people up
Louisville Metro is the merged city-county government for Jefferson County, so the table spans far more than the city proper — and the contractor is named on about a third of rows (8,075 of 22,902 measured across the whole table), with no owner column at all. Both matter for what a report can tell you: a Louisville permit is reliably an address, a scope and a declared cost, and only sometimes a company.
