Chicago Housing Data: Sources and Methodology
Homzora editorial team · Updated September 13, 2026
This page documents where Homzora's Chicago figures come from, how they are derived, and what they cannot tell you. It applies to every Chicago guide and dataset on this site. If a figure appears without a source recorded here, treat it as an error and tell us.
Current status
Homzora has no Chicago survey data. Every figure published in the Chicago edition is compiled from third party sources or taken from public records, and none of it is survey derived. No renter satisfaction score, demand index or affordability index is published for this city, because we have not collected the responses that would support one.
Geography
Chicago coverage means the City of Chicago. Suburban municipalities in Cook County and beyond are outside it. This matters more here than in most cities, because Cook County and Evanston operate their own landlord tenant ordinances with requirements that differ from the Chicago RLTO. A property a short distance outside the city limits may sit under an entirely different set of rules.
Within the city, neighborhood boundaries come from City of Chicago community area definitions. Rent aggregators use their own neighborhood labels, which do not always match, and that is one reason figures differ between sources.
Chicago, Boston and Atlanta figures are never pooled or compared without stating the different geography and method. Each edition is independent.
Legal and ordinance material
Chicago has one of the most detailed local landlord tenant ordinances in the country, and most of what we publish about tenant rights here comes from it rather than from state law.
Our source is the published text of the Municipal Code of Chicago Chapter 5-12, together with the annual Security Deposit Interest Rate notice issued by the City Comptroller and the summary published by the Department of Housing. Where we cite a provision we give the section number and the date we verified it.
State level material, including the Illinois Rent Control Preemption Act, is cited to the relevant statute.
Where published sources disagree about what a rule requires, we record the disagreement rather than choosing the version we prefer. Nothing on this site is legal advice, and a question about a particular tenancy belongs with an attorney or a legal aid organization.
Transit information
CTA fare figures come from the Chicago Transit Authority and the Northern Illinois Transit Authority. Both are official sources and they agree with each other on every figure we publish.
Several third party guides report different numbers, including a charge for transfers and a higher monthly pass price. Those figures do not appear on either authority page. We publish the authority figures and record the disagreement in the dataset itself.
We do not publish commute times. A door to door journey depends on walking distance, waiting, transfers, time of day and service conditions, none of which we have measured. In vehicle time is a component of a commute rather than the commute itself, and treating the two as equivalent produces figures that look precise and are not.
Rent figures
Where a guide cites a neighborhood rent average, it names the source, the period the source covers, and the date we checked it.
Those averages combine all unit sizes into one number. A neighborhood with many large apartments produces a high average even when its one bedrooms are ordinary, so an all sizes figure is a relative comparison rather than a budgeting figure. It is not a listing quote and it is not specific to any bedroom count.
Aggregator coverage also emphasises larger managed buildings, which means smaller landlords and units filled by word of mouth are underrepresented. Concessions and fees are excluded, so an advertised rent with a month free is not the effective rent.
We have not yet compiled multi source rent ranges by bedroom count for Chicago neighborhoods, as we have for other editions. Until we have, single source averages are labeled as such.
What our figures cannot tell you
- They are not what you will pay. Ask any property for written quotes on the specific homes you are considering.
- They exclude fees. Parking, pet rent, amenity charges, utility administration and mandatory insurance are not in any published rent figure.
- They are a snapshot. Observation dates are recorded. Rents move.
- They are not a legal reference. Where we describe what an ordinance requires, we are summarizing published text rather than advising on your situation.
Review and correction
Each dataset records its observation window and the date it was compiled. Rent figures are reviewed when sources publish updated data. Transit information is checked before any guide citing it is published, because fares change. Ordinance material is verified against published text and rechecked on review, and the deposit interest rate in particular changes every January.
Where evidence is insufficient to support a figure, we publish the gap rather than an estimate. If you find an error, tell us and we will correct it and note the correction.
