Zadock 'Zed' Martin and his sons built a dam and grist mill on the Platte River in 1838 near an existing village called Martinsville; by 1839 the settlement was platted and renamed Platte City. It exists because it was made the seat of Platte County. source 1 source 2

The housing stockmedian built 2006
The median home sold here was built in 2006. Most of what sells was built between 1967 and 2025. The Census puts the median year built for all housing at 1978, so the homes changing hands skew newer than the stock as a whole. 68% of sales included finished basement space beyond the above-grade footprint - which matters here, because square footage quoted above grade can understate a house considerably.
By property type, sales broke down as Single Family (251), Townhouse (14), Half Duplex (2), Patio/Villa (2).
