Merrillville is a large unincorporated community and census-designated place in Lake County, Indiana, located in the Chicago metropolitan area. As part of Indiana's Northwest corner, Merrillville has a large and diverse rental market. The community has not enacted any local tenant protection ordinances — renters rely entirely on Indiana state law for their housing rights.
Indiana law prohibits local rent control (Ind. Code § 32-31-1-20), meaning Merrillville landlords may raise rents by any amount with proper notice. State law provides important protections on security deposits (45-day return deadline with itemized statement), implied warranty of habitability, anti-retaliation provisions, and a strict prohibition on self-help eviction. Indiana's tenant remedies for habitability issues are, however, acknowledged to be less robust than many other states, making legal assistance important when issues arise.
This guide summarizes Indiana state law as it applies to Merrillville renters. It is not legal advice. Tenants facing urgent housing situations should contact Indiana Legal Services or the Lake County Bar's lawyer referral service.
Merrillville has no rent control. Indiana state law under Ind. Code § 32-31-1-20 prohibits any political subdivision of Indiana — including Lake County and any municipality within it — from enacting any form of rent control or rent stabilization. This preemption applies statewide and permanently. No local rent regulation exists in Merrillville.
Merrillville landlords may increase rent by any amount at any time. The only procedural requirement is that for month-to-month tenancies, at least 30 days' written notice must be given before the landlord terminates or materially changes the tenancy (Ind. Code § 32-31-1-1). Fixed-term leases lock in rent for the duration of the term; increases can only apply at renewal. There are no caps on rent increase amounts and no government body that reviews or approves landlord pricing decisions.
Renters in Merrillville's busy Lake County rental market should review their leases carefully, understand the notice requirements, and plan accordingly when landlords seek to raise rents at renewal.
Indiana state law provides Merrillville renters with the following baseline protections.
Implied Warranty of Habitability: Indiana recognizes an implied warranty of habitability in residential leases. Landlords must maintain rental units in a condition fit for human habitation, including functioning heat, safe plumbing and electrical systems, weathertight structure, and freedom from vermin. Tenants must give the landlord written notice of the deficiency and allow a reasonable time to repair. Indiana's remedies for non-compliance are more limited than many other states — tenants should consult Indiana Legal Services before taking self-help action.
Security Deposit (Ind. Code § 32-31-3-12): Landlords must return deposits within 45 days of move-out with a written itemized statement. Wrongful withholding may result in the withheld amount plus attorney fees. See Security Deposit section for full details. Indiana does not cap deposit amounts.
Notice to Terminate (Ind. Code § 32-31-1-1): Month-to-month tenants must receive at least 30 days' written notice before the landlord terminates the tenancy. Tenants must provide equivalent notice when leaving a month-to-month arrangement.
Anti-Retaliation (Ind. Code § 32-31-8-6): Landlords cannot retaliate against tenants for reporting code violations or exercising legal rights by raising rent or initiating eviction proceedings. Retaliation may be raised as a defense in court.
Self-Help Eviction Prohibited (Ind. Code § 32-31-1-8): Landlords may not change locks, remove doors, shut off utilities, or physically remove a tenant without a court order. Such conduct is illegal in Indiana and may result in civil liability.
Security deposit rules in Merrillville are governed by Indiana's Security Deposit Statute, Ind. Code §§ 32-31-3-9 through 32-31-3-19. Indiana does not cap the amount a landlord may charge as a security deposit — the amount is determined by the lease agreement.
Move-In Checklist: Within a reasonable time after move-in, tenants should document the unit's condition in writing. While Indiana law does not impose the same strict move-in inventory rules as some states, written documentation protects tenants against improper damage claims at move-out. Take dated photographs and video at both move-in and move-out.
45-Day Return Deadline: After you vacate, your landlord has 45 days to return your deposit along with a written, itemized statement of any deductions (Ind. Code § 32-31-3-12). This is longer than the deadline in most states. Deductions may cover unpaid rent and damage beyond normal wear and tear. Normal wear and tear cannot be charged.
Penalty for Non-Compliance: If your landlord wrongfully withholds any portion of your deposit, you may sue to recover the amount wrongfully withheld plus reasonable attorney fees under Ind. Code § 32-31-3-12. Note that Indiana does not impose double or treble damages for wrongful withholding — the remedy is the actual amount withheld plus fees.
Security deposit claims can be filed in Lake County Small Claims Court. Always provide your landlord with a written forwarding address when you vacate to start the 45-day clock.
Indiana landlords must follow a court-supervised process to evict a tenant. Self-help eviction — changing locks, removing belongings, cutting utilities — is illegal under Ind. Code § 32-31-1-8 and may result in civil liability.
Step 1 — Written Notice: For nonpayment of rent, Indiana requires a written notice to pay or vacate — typically 10 days under common practice. For lease violations, a notice to comply or quit is required. To terminate a month-to-month tenancy without cause, at least 30 days' written notice is required (Ind. Code § 32-31-1-1).
Step 2 — Complaint for Eviction: If the tenant does not comply, the landlord files a Complaint for Eviction in the Lake County Superior Court or Small Claims Court. The tenant is served with a summons and the hearing is typically scheduled within 20–30 days.
Step 3 — Court Hearing: Both parties present evidence. Tenants may raise defenses including improper notice, habitability violations, and retaliation under Ind. Code § 32-31-8-6. Contact Indiana Legal Services (indianalegalservices.org) before the hearing if you need assistance.
Step 4 — Writ of Possession: If the court rules for the landlord and the tenant has not vacated, the court may issue a Writ of Possession directing law enforcement to remove the tenant. Only law enforcement acting under court authority may physically remove a tenant.
No. Merrillville has no rent control. Indiana state law under Ind. Code § 32-31-1-20 prohibits any political subdivision from enacting rent control ordinances. Landlords may raise rent by any amount with proper advance written notice.
There is no legal limit on rent increases in Merrillville. Indiana's statewide preemption (Ind. Code § 32-31-1-20) bars any local rent cap. For month-to-month tenancies, your landlord must give at least 30 days' written notice before the change takes effect (Ind. Code § 32-31-1-1). Fixed-term leases lock in rent until renewal.
Your landlord must return your deposit — with a written itemized statement of deductions and any remaining balance — within 45 days of move-out (Ind. Code § 32-31-3-12). If the landlord wrongfully withholds any portion, you may sue to recover the withheld amount plus attorney fees. Indiana does not cap deposit amounts.
For nonpayment of rent, Indiana practice typically requires a written 10-day notice to pay or vacate. For lease violations, a cure-or-quit notice is required. To terminate a month-to-month tenancy without cause, at least 30 days' written notice is required (Ind. Code § 32-31-1-1). A court order is always required before you can be removed.
No. Self-help eviction is illegal in Indiana under Ind. Code § 32-31-1-8. A landlord who changes your locks, removes doors, or shuts off utilities to force you out may face civil liability. Only law enforcement acting on a court order can lawfully remove a tenant. Contact Indiana Legal Services if you experience an illegal lockout.
Indiana recognizes an implied warranty of habitability. Give your landlord written notice of the needed repair and keep a copy. If the landlord fails to act within a reasonable time, you may have remedies depending on the severity of the defect. Note that Indiana's tenant remedies for habitability non-compliance are more limited than many other states. Contact Indiana Legal Services (indianalegalservices.org) before withholding rent or taking any unilateral action.
