Questions about Louisville landAnswers from the public records
How many parcels are in Louisville, CO?
8,446 parcels on the 2026 Boulder County tax roll (county file Oct 2026) inside the Census Bureau's boundary for Louisville, which can differ from its own limits at the edges, covering 4,402 acres.
How much vacant land is in Louisville, CO?
Boulder County's vacant-land class failed our aerial check (17 of 60 sampled lots were in use or doubtful: park and HOA strips, parking islands, a pond, yards, road strips), so we don't call any parcel here vacant land.

The median parcel is 0.17 acre, from 7,561 parcels with a recorded size.
How much of Louisville is in a flood zone?
0.9% of parcels are in a FEMA special flood hazard area (National Flood Hazard Layer, as of Oct 2026). Check each parcel's own flood line before you buy.
Are there wetlands in Louisville?
0.3% of parcels are a quarter or more wetland on the USFWS National Wetlands Inventory, a mapping guide, not a legal delineation.
What is Louisville zoned?
Our map has no zoning layer for Louisville yet. Ask the city's or Boulder County's planning office which zoning applies to a parcel.
Are there land prices for Louisville?
No land-price range is shown for Louisville yet. We print no land-price range for Boulder County yet. Some parcel cards here carry their own price range or rough estimate.
Where does this data come from?

Land sale prices
We hold this county's recorded deeds, but its file does not mark which sales are arm's-length land sales, so this page prints no land price range yet.
