Local Market Data
St. Louis County Apartment Market
Figures gathered October 2026 from public market data.
If you plan to sell commercial property in St. Louis County, MO, start with the renter base behind every multifamily deal. St. Louis County counts 127,319 renter households, a 30.8% share of all occupied homes, per the Census Bureau's 2020-2024 American Community Survey. That share trails Missouri's statewide 31.9% renter rate, but two cities inside the county, Maryland Heights and University City, each top 43% renters.
Apartment buildings carry a meaningful slice of that demand. Some 74,065 St. Louis County housing units, or 16.6% of the stock, sit in buildings with five or more units. Median gross rent reached $1,209, up 23.0% from the 2015-2019 survey, and now runs 17.0% above Missouri's $1,033 median. Rental vacancy stands at 5.0%, so rents, vacancy and tax costs still shift from one St. Louis County city to the next.

Maryland Heights and University City post the highest renter concentrations in the comparison table below, each above 43%.

Property taxes and assessment in St. Louis County
Missouri assesses residential property, including apartment buildings, at 19% of market value, while commercial and other property is assessed at 32%, under RSMo Section 137.016. St. Louis County reassesses real property in odd-numbered years, so a sale this cycle can feed directly into the next assessment.
The St. Louis County Assessor sets the assessed value, and the county collector applies the taxing rate to produce the bill. Rates stack across the county, school district, fire district and other bodies specific to each parcel, so no single county-wide rate applies to every address. Pull the parcel's current assessment and rate breakdown from the assessor's office before pricing a multifamily building.
Missouri law also bars local rent control. RSMo Section 441.043 prevents St. Louis County and its cities from regulating rent on private residential or commercial property, a preemption amended effective August 28, 2025 to also block local deposit caps and source-of-income rules.
What this means if you sell in St. Louis County
When you sell commercial property in St. Louis County, MO, you sell into a market where renters hold 30.8% of households and 16.6% of units sit in 5+ unit buildings. The 5.0% rental vacancy rate is tight, and buyers will test your rent roll against that backdrop. A Wildwood property in a market with an 8.2% renter share draws a different buyer than a Maryland Heights building where renters make up 43.2% of households.
Rent burden shapes buyer underwriting too. With 48.3% of St. Louis County renters already paying 30% or more of income on rent, buyers model limited room for further increases without losing tenants. Taxes come next: expect a buyer to request the current assessed value and rate stack rather than rely on your latest bill, since reassessment occurs in odd-numbered years.
As a multifamily buyer in St. Louis County, we review 5+ unit buildings from Florissant to Wildwood as they stand today. Send a current rent roll, a T-12 and the latest tax statement, and we will price the building on those numbers.
