Wentzville is one of Missouri's fastest-growing cities, located in St. Charles County west of St. Louis, with a population that has grown to approximately 50,000 in recent years. The city's rapid residential expansion has brought a large number of new rental units to the market. Like all Missouri municipalities, Wentzville is governed entirely by Missouri state law when it comes to landlord-tenant rights — the city has enacted no local rent control, just-cause eviction requirement, or supplemental tenant ordinances.
Missouri's landlord-tenant framework provides Wentzville renters with baseline protections through Mo. Rev. Stat. Chapters 441 and 535: a cap on security deposits, a 30-day return deadline, an implied warranty of habitability, anti-retaliation rights, and a mandatory court process before any eviction. These protections are meaningful, but Missouri remains one of the states where tenant rights are more limited — particularly because state law prohibits rent control.
This page summarizes applicable law as of April 2026 for general informational purposes only. It is not legal advice. For guidance on specific situations, contact Legal Services of Eastern Missouri or a licensed Missouri attorney.
Wentzville has no rent control, and Missouri state law prohibits the city from enacting any. Mo. Rev. Stat. § 441.043 explicitly preempts all Missouri municipalities — including Wentzville and St. Charles County — from enacting or enforcing rent control ordinances. This preemption has been in place since 1986.
A Wentzville landlord may raise rent by any dollar amount at the end of a lease term or, for month-to-month tenancies, with at least 30 days' advance written notice (Mo. Rev. Stat. § 441.060). There is no cap, no percentage limit, and no local body to appeal to regarding the size of an increase. Tenants who cannot afford a proposed increase may negotiate with their landlord or seek other housing.
The following Missouri state protections apply to all residential tenancies in Wentzville:
Implied Warranty of Habitability: Missouri courts require landlords to maintain rental units in a safe, sanitary condition fit for human habitation — including functioning heat, running water, weatherproof structure, and compliance with housing codes. Material breach may allow tenants to seek rent reductions or lease termination.
Security Deposit Rules (Mo. Rev. Stat. § 535.300): Deposits are capped at two months' rent and must be returned with an itemized statement within 30 days of move-out. Wrongful withholding results in twice the withheld amount plus attorney's fees. See the Security Deposit section for full details.
Notice to Terminate (Mo. Rev. Stat. § 441.060): Either party must give at least 30 days' written notice to end a month-to-month tenancy.
Anti-Retaliation (Mo. Rev. Stat. § 441.053): Landlords may not retaliate against tenants for reporting code violations, filing complaints, or exercising legal rights. Prohibited retaliation includes eviction filings, rent increases, and service reductions.
Lockout and Self-Help Eviction Prohibition (Mo. Rev. Stat. § 534.030): Self-help eviction — changing locks, shutting off utilities, removing tenant belongings — without a court order is illegal and exposes the landlord to civil liability.
Security deposit rules in Wentzville are governed by Mo. Rev. Stat. § 535.300:
Cap on Amount: Landlords may not collect more than two months' rent as a security deposit. Any lease provision demanding a higher amount is unenforceable to that extent.
Return Deadline: After the tenant vacates, the landlord has 30 days to return the unused deposit with a written itemized statement of any deductions. Allowable deductions are limited to unpaid rent and damage beyond normal wear and tear.
Penalty for Wrongful Withholding: Failure to comply entitles the tenant to twice the wrongfully withheld amount plus reasonable attorney's fees (Mo. Rev. Stat. § 535.300(5)).
No Interest or Escrow Requirement: Missouri law does not require landlords to hold deposits in a separate account or pay interest.
Tenant Tip: Provide your forwarding address in writing when you vacate, and document the unit's condition with dated photos at move-in and move-out.
Evictions in Wentzville must follow Missouri's mandatory legal process. No landlord may remove a tenant through self-help; only a court judgment enforced by a law enforcement officer permits physical removal.
Step 1 — Written Notice: The landlord must provide appropriate written notice before filing. For month-to-month terminations without fault, at least 30 days' written notice is required (Mo. Rev. Stat. § 441.060). For nonpayment, local practice involves a written demand before filing. For lease violations, written notice and a reasonable cure period are expected.
Step 2 — Filing in Circuit Court: If unresolved, the landlord files an unlawful detainer action in St. Charles County Circuit Court. Self-help eviction is illegal under Mo. Rev. Stat. § 534.030.
Step 3 — Court Hearing: Both parties may appear and present evidence. Tenants may raise defenses including improper notice, retaliation, or habitability breach. Contact Legal Services of Eastern Missouri for assistance before the hearing.
Step 4 — Writ of Possession: A court judgment for the landlord results in a writ of possession executed by a law enforcement officer. Any landlord who acts without this writ commits illegal self-help eviction and may face civil liability.
No Just-Cause Requirement: Neither Missouri nor Wentzville requires just cause to decline lease renewal.
No. Wentzville does not have rent control, and Missouri state law (Mo. Rev. Stat. § 441.043) prohibits any city or county from enacting a rent control ordinance. This statewide preemption has applied since 1986. Landlords in Wentzville may raise rent by any amount, subject only to the required advance notice period.
There is no legal cap on rent increases in Wentzville. Missouri's prohibition on local rent control (Mo. Rev. Stat. § 441.043) means landlords may raise rent by any amount. For month-to-month tenancies, at least 30 days' written notice is required before the new rent takes effect (Mo. Rev. Stat. § 441.060). Fixed-term leases cannot be raised mid-term unless the lease expressly allows it.
Under Mo. Rev. Stat. § 535.300, your landlord must return your deposit — or the balance after lawful deductions — within 30 days of the date you vacate, along with a written itemized statement. If the landlord wrongfully withholds any portion, you may sue for twice the amount withheld plus reasonable attorney's fees. Always provide a written forwarding address when you move out.
For a month-to-month tenancy, your landlord must give at least 30 days' written notice to terminate (Mo. Rev. Stat. § 441.060). For nonpayment of rent, a written demand is expected before filing. Regardless of the reason, your landlord must obtain a court judgment before you can be physically removed. Self-help eviction is illegal under Mo. Rev. Stat. § 534.030.
No. Missouri law (Mo. Rev. Stat. § 534.030) prohibits self-help eviction. A landlord who changes your locks, removes your belongings, or cuts off heat, water, or electricity without a court order is acting illegally. If this occurs, contact law enforcement and seek immediate help from Legal Services of Eastern Missouri (lsem.org). You may be entitled to damages.
Missouri's implied warranty of habitability requires your landlord to maintain essential services like heat, water, and structural safety. If your landlord ignores repair requests, document everything in writing, report violations to St. Charles County code enforcement, and contact Legal Services of Eastern Missouri for guidance. Missouri courts may allow rent reductions or lease termination for serious habitability breaches, but legal advice is strongly recommended before withholding rent.
