Ottawa is the county seat of LaSalle County, located in north-central Illinois along the Illinois and Fox Rivers. Like many smaller Illinois cities, Ottawa has a mix of single-family rentals, older multi-unit buildings, and newer apartment complexes. Renters in Ottawa are protected entirely by Illinois statewide tenant law — the city has not enacted any local tenant protections beyond what state statutes provide.
The most common questions Ottawa renters have involve security deposit disputes, the eviction process, and what to do when a landlord fails to make repairs. All of these issues are governed by Illinois statutes, including the Security Deposit Return Act (765 ILCS 710), habitability rules rooted in Illinois common law, and the Forcible Entry and Detainer Act (735 ILCS 5/9-101 et seq.), which governs evictions statewide.

Ottawa has no rent control, and Illinois state law prohibits any municipality from enacting it. The Illinois preemption statute — 765 ILCS 720/1 — explicitly bars cities, counties, and other local governments from adopting any ordinance that controls the amount of rent charged for private residential property. This law has been in effect statewide since 1997 and applies equally to large cities like Chicago and small cities like Ottawa.
In practical terms, this means your landlord in Ottawa can raise your rent by any amount at the end of a lease term, or with proper notice during a month-to-month tenancy. There is no cap, no required justification, and no city approval needed for rent increases. Your only protection against a mid-lease increase is the lease agreement itself — a landlord cannot raise rent during a fixed lease term without your written consent, because doing so would breach the contract.
If you are on a month-to-month tenancy, a landlord must give you at least 30 days written notice before a rent increase takes effect (735 ILCS 5/9-207). You are never obligated to accept a new rent amount — but if you stay past the notice date, you may be treated as having agreed to the new terms.
Illinois state law provides several important protections for all renters in Ottawa, regardless of whether a local ordinance exists.
Security Deposit Rules (765 ILCS 710 & 765 ILCS 735): Landlords who hold a security deposit must return it — along with an itemized written statement of any deductions — within 30 days of the tenant vacating the unit. If the landlord fails to comply, the tenant may be entitled to recover damages. Landlords who own 25 or more units and hold deposits for more than six months must pay interest on those deposits (765 ILCS 735/1).
Implied Warranty of Habitability: Under Illinois common law (recognized in Glasoe v. Trinkle, 107 Ill. 2d 1 (1985)) and affirmed by subsequent courts, landlords must maintain rental units in a habitable condition throughout the tenancy. This includes functioning plumbing, heat, structural integrity, and freedom from pest infestations. If a landlord fails to make repairs after written notice, tenants may have remedies including rent withholding or repair-and-deduct, though these remedies carry legal risk and tenants should seek legal advice before using them.
Notice to Terminate (735 ILCS 5/9-207): Either a landlord or tenant may terminate a month-to-month tenancy by giving at least 30 days written notice before the end of a rental period. For week-to-week tenancies, seven days notice is required. Fixed-term leases expire at the end of the term unless renewed.
Anti-Retaliation Protections (765 ILCS 720/1): A landlord may not retaliate against a tenant for complaining to a government agency about code violations, joining a tenant organization, or exercising any legal right. Retaliatory acts include rent increases, eviction notices, and reduction of services. A tenant who proves retaliation may recover actual damages, attorney fees, and other relief.
Lockout and Utility Shutoff Prohibition (735 ILCS 5/9-101 et seq.): Self-help eviction is illegal in Illinois. A landlord cannot change locks, remove doors or windows, shut off utilities, or remove the tenant's belongings to force them out without a court order. Tenants subjected to an illegal lockout may seek emergency injunctive relief in court.
Illinois does not set a statutory cap on the amount a landlord can charge as a security deposit in Ottawa. Landlords may charge any amount they and the tenant agree to, though the amount is typically negotiated at lease signing.
Return deadline: Under the Illinois Security Deposit Return Act (765 ILCS 710/1), a landlord must return the security deposit — minus any lawful deductions — within 30 days after the tenant vacates the unit. If the landlord intends to make deductions, they must provide the tenant with an itemized written statement of damages and the cost of repairs within that same 30-day window. Deductions may only be taken for actual damage beyond normal wear and tear, or for unpaid rent.
Penalty for wrongful withholding: If a landlord fails to return the deposit or provide the required itemized statement within 30 days, the tenant has the right to sue for the amount wrongfully withheld. Under 765 ILCS 710/1, a landlord who violates the act may be liable for the full amount of the deposit, court costs, and reasonable attorney fees. For landlords who own 25 or more units and hold deposits longer than six months, the Illinois Security Deposit Interest Act (765 ILCS 735/1) requires the payment of interest at a rate set by the state Comptroller.
Practical tip: Document the condition of your unit thoroughly at move-in and move-out with photographs and written notes. Send your forwarding address to your landlord in writing so they have no excuse for failing to return the deposit on time.
Evictions in Ottawa are governed by the Illinois Forcible Entry and Detainer Act (735 ILCS 5/9-101 et seq.). A landlord cannot remove a tenant without first serving proper written notice and then obtaining a court judgment. There is no just-cause requirement in Ottawa — a landlord may choose not to renew a lease or may terminate a month-to-month tenancy for any lawful reason, as long as proper notice is given.
Step 1 — Written Notice: The type and length of notice depends on the reason for eviction:
Step 2 — Court Filing: If the tenant does not comply with the notice, the landlord may file an eviction complaint in LaSalle County Circuit Court. The tenant will be served with a summons and given the opportunity to appear and present a defense at a hearing.
Step 3 — Court Hearing: Both parties appear before a judge. If the court rules in the landlord's favor, it issues an order of possession. If the tenant has defenses — such as the landlord's failure to maintain habitability or retaliatory motive — those can be raised at this stage.
Step 4 — Enforcement: Only a court-appointed sheriff or sheriff's deputy may physically remove a tenant after a court judgment. A landlord who attempts to remove a tenant without a court order commits an illegal lockout.
Self-help eviction is prohibited: Under Illinois law (735 ILCS 5/9-101), a landlord cannot change locks, remove doors, shut off utilities, or take any action to force a tenant out without going through the court process. Tenants facing an illegal lockout may seek emergency relief in LaSalle County Circuit Court and may be entitled to damages.
