Security deposit limits, eviction notices, rent control, and more for Rockford, Illinois.
Every rule on this page is drawn from state statutes and municipal codes and summarized with AI assistance. Each one cites the statute it's based on and links to a published text of that law so you can read it firsthand. Where a page says a city or county has no local rule on a topic, that means none was found for the topics covered here — not that none exists. Local governments also regulate rental housing in ways these pages don't track, including registration, licensing, inspections and habitability standards. These summaries may be incomplete or out of date, laws change often, and every property and tenancy has specifics a summary can't capture — so treat this as a starting point for your own research, not as legal advice, and check with the local jurisdiction and a qualified attorney before acting on your particular situation.

Rockford follows Illinois state law for all landlord-tenant matters and has no local rent control ordinance, as Illinois's Rent Control Preemption Act of 1997 prohibits all municipalities from enacting rent stabilization. Illinois imposes no statewide security deposit cap, and landlords must return deposits within 45 days for buildings with 5 or more units. Eviction for nonpayment requires a 5-day notice, and month-to-month tenancies require 30 days' notice to terminate.
As an alternative to increasing the customary security deposit, a landlord may negotiate an interest-bearing escrow account to ensure funds for restoration of premises modified for a tenant with a disability. The escrow amount may not exceed the cost of the restorations, must be paid over a reasonable period, and must accrue interest to the tenant.
When a landlord permits a tenant with a disability to make a reasonable modification and requires restoration of the premises, the landlord may not increase the tenant's customary security deposit because of the tenant's disability.
These state-level rules apply in Rockford where no local override exists.
After rent is due, a landlord may serve a written demand stating that the lease will terminate unless the demanded rent is paid within a period of at least five days after service. If the tenant does not timely pay, the landlord may treat the lease as terminated and commence an eviction or ejectment action without further demand.
If the landlord does not provide the required damage statement and receipts, the landlord must return the security deposit in full within 45 days after the tenant vacated. The return must be delivered in person or by postmarked mail.
Non-optional fees must be disclosed clearly and conspicuously in the rental listing or an accompanying web link. The listing or lease disclosure must state whether utilities are included in rent.
