Short-Term Rentals in Illinois as of 2026

Thinking About Owning a Chicago Airbnb? What Illinois Property Owners Should Know About Short-Term Rental (STR) Rules

Short-term rentals can be attractive to property owners and real estate investors. A furnished apartment, condominium, or single-family home may appear capable of generating substantially more income as a short-term rental than under a traditional year-long lease.

But there is an important legal question that should come before calculating projected Airbnb income:

Is short-term rental use actually permitted at this property?

In Illinois, the answer can depend heavily on where the property is located, how it is zoned, what type of property it is, and whether private restrictions apply to it.

A property being physically suitable for an Airbnb does not necessarily mean that it can legally be operated as one.

Short-Term Rental Rules Are Often Local

Illinois property owners should not assume there is one universal set of “Illinois Airbnb rules.”

Municipalities can impose their own requirements affecting short-term rentals, including licensing or registration requirements, zoning restrictions, occupancy rules, taxes, and restrictions applicable to particular areas.

That makes the specific property address important.

Two otherwise similar properties located only a short distance apart may be subject to different restrictions.

For investors, this distinction should be investigated before purchasing the property, particularly when projected short-term-rental income is an important part of the investment decision.

Chicago Has Its Own Short-Term Rental Framework

Chicago provides a particularly useful example of why property-specific research matters.

Under the Chicago Zoning Ordinance, a “shared housing unit” is a type of lodging use involving a dwelling unit containing six or fewer sleeping rooms that is rented, in whole or in part, for transient occupancy. Chicago separately regulates other lodging uses, including vacation rentals.

Whether that use is permissible can depend on the property’s zoning.

In fact, Chicago’s Department of Planning and Development has issued property-specific zoning determinations addressing whether proposed Airbnb or shared-housing operations are permitted at particular properties.

In one 2024 determination involving 28 E. Jackson Boulevard, the City concluded that six proposed non-owner-occupied short-term rentals could not operate because lodging, including shared housing, was not a permitted use under the property’s governing Planned Development.

That is an important lesson for prospective investors:

A property can be perfectly usable as a residence while still being unsuitable for your intended short-term-rental business.

Some Chicago Areas Can Restrict New Short-Term Rentals

Chicago law also permits the creation of Restricted Residential Zones.

Through that process, qualifying residential precincts can restrict new or additional shared-housing units and/or vacation rentals from operating within the precinct.

This is another reason investors should investigate the specific location rather than merely searching Airbnb to see whether other listings appear nearby.

Existing Airbnb listings are not a legal opinion.

A neighboring property appearing on a hosting platform does not establish that:

• The neighboring operation is legally compliant.

• Your property has the same zoning.

• Your building has the same restrictions.

• Your proposed use qualifies under the same rules.

• A new short-term-rental operation can currently be established at your address.

Zoning Is Only One Part of the Analysis

Even when local zoning permits short-term-rental activity, a property owner may have additional restrictions to consider.

For example, a condominium declaration may restrict rentals or impose minimum lease terms.

A homeowners’ association may have its own rental rules.

A lease may prohibit a tenant from subletting or operating a short-term rental.

A mortgage, insurance policy, building rule, or other agreement may also create obligations that should be reviewed before the property is advertised to transient guests.

In other words:

“The city allows it” and “I am allowed to do it” are not necessarily the same question.

Both governmental regulations and private property restrictions should be considered.

Do Not Forget About Taxes

Short-term rental income can also carry state and local tax obligations.

Illinois’ Hotel Operators’ Occupation Tax Act applies broadly to accommodations in which the public can obtain living, sleeping, or housekeeping quarters for consideration. Illinois administrative regulations also address various forms of accommodations within the State’s hotel-tax framework.

Illinois has also revised how certain transactions involving hotel marketplace facilitators and short-term-rental hosting platforms are treated, including provisions effective July 1, 2026.

Local hotel or accommodation taxes may apply as well.

Property owners should therefore confirm which taxes apply and whether a hosting platform collects and remits particular taxes on their behalf rather than assuming that listing through a platform automatically resolves every tax obligation.

The Most Important Time to Investigate the Rules Is Before You Buy

For a buyer purchasing a home strictly as a residence, short-term-rental regulations may never become relevant.

For an investor whose financial projections depend upon Airbnb or other short-term-rental income, they can be critical.

Consider a property where an investor projects:

Traditional monthly rent: $2,500

versus

Projected short-term-rental revenue: $5,000 per month

If the transaction only makes financial sense at the second number, discovering after closing that the property cannot legally operate as a short-term rental fundamentally changes the investment.

That is why the legal and regulatory investigation should occur before the buyer becomes irrevocably committed to the transaction whenever possible.

A Pre-Purchase STR Checklist

Before purchasing a property that you intend to operate as a short-term rental, consider investigating each of the following:

1. Does the municipality permit short-term rentals?

Local ordinances can regulate or restrict short-term-rental activity. Do not assume that rules applicable in one Illinois municipality apply in another.

2. Does the property’s zoning permit the proposed use?

A property being legally usable as a residence does not automatically establish that transient lodging or short-term-rental use is permitted.

3. Is a license or registration required?

Some local governments require registration, licensing, or other approval before a short-term rental can legally operate.

4. Is the property located within a restricted area?

Certain locations may restrict new or additional short-term rentals even where similar properties elsewhere in the municipality are permitted to operate.

5. Is owner occupancy required?

Rules may differ depending upon the municipality, property type, and whether the owner occupies the property as a primary residence.

6. Does the condominium association or HOA permit short-term rentals?

Private restrictions can prohibit short-term rentals even where municipal zoning would otherwise permit the use. Review applicable condominium declarations, bylaws, HOA rules, and amendments.

7. Are there minimum rental periods?

Condominium declarations, leases, association rules, or local regulations may require minimum rental periods that make nightly or short-term stays impermissible.

8. What taxes apply?

State and local lodging-related taxes may apply. Property owners should determine what must be collected or remitted and what, if anything, a hosting platform handles on their behalf.

9. Does the property’s insurance cover short-term-rental use?

Ordinary residential insurance may not adequately address commercial or transient occupancy. Coverage should be confirmed before guests occupy the property.

10. Does the investment still make sense without short-term-rental income?

This may be the most important financial question of all.

If the purchase only works financially because of projected Airbnb revenue, a buyer should understand the consequences if short-term-rental use is prohibited, restricted, suspended, or otherwise unavailable.

Buying A Short Term-Rental Is Still a Real Estate Transaction

It can be easy to focus on nightly rates, occupancy projections, furniture, cleaning costs, and platform fees.

But before any of those questions matter, the buyer is purchasing real estate.

That means title, zoning, contracts, association restrictions, financing, taxes, insurance, and local regulation can matter just as much as projected rental revenue.

A short-term-rental investment should therefore be evaluated not only as a potential business, but also as a real estate transaction involving a particular property subject to a particular set of rules.

How can I qualify My Current 2-4 Unit / Non-owner occupied building for Airbnb in Chicago?

Chicago’s short-term rental regulations contain a process known as a Commissioner’s Adjustment, which may provide a path forward for certain properties that do not otherwise satisfy the City’s standard short-term rental requirements.

But an adjustment is not automatic. Eligibility depends on the property and the circumstances, and the owner must demonstrate why an exception is warranted. Chicago also limits the number or percentage of units within certain buildings that may operate as short-term rentals, making building-level eligibility another important consideration. Property owners should also account for the costs associated with the process, including application and licensing fees imposed by the Chicago Department of Business Affairs and Consumer Protection (BACP). For investors in particular, these regulatory requirements and expenses should be evaluated before purchasing a property in reliance on projected short-term rental income.

Casper Legal Services has successfully assisted property owners and investors with evaluating and pursuing Commissioner’s Adjustments and, to date, has obtained approval in every Commissioner’s Adjustment matter the firm has handled.
