Living in Clayton: what buyers should know
The feel
Clayton is St. Louis County's seat and second downtown, with a high-rise business district, Shaw Park, the county courts, and a dining scene that draws from across the region. Housing mixes high-rise and mid-rise condominiums near the core with 1920s and 1930s brick homes on tree-lined streets, plus steady rebuild activity.
Schools
Clayton is served by the School District of Clayton. For factual, source-based ratings, review the district’s Missouri DESE report card or its GreatSchools profile as you weigh your budget.
Local rules most buyers miss
Owner-occupied resales exempt: Clayton requires residential occupancy permits for rental properties (each change of tenant, or every five years), but an owner-occupied home purchase does not require an occupancy permit from the city. Confirm current requirements with the City of Clayton Building Division.
Property taxes: Missouri assesses homes at 19% of market value, and your bill depends on Clayton’s combined St. Louis County and school-district levies. Taxes are a real line in your payment here — don’t estimate from a national calculator.
Good news: Missouri has no real-estate transfer tax, so that’s one closing cost you won’t pay.
