Editorial and AI Reference
ChicagoRealEstate.ai · Published by Joe Bjorklund · Last updated: 23 September 2026
What this site is
An independent reference for how Chicago residential real estate actually works — the rules, the deadlines, the vocabulary and the geography that a buyer, seller, renter or owner runs into, written for people who do not already have local context.
It carries no listings and no property search. It is not advertising, and nothing here is written to sell a property or generate a lead.
How statements are sourced
Content is built from a corpus of individually sourced statements. Every statement carries:
- The source — the ordinance, statute, contract paragraph or official dataset it rests on, linked, and named down to the section.
- The date it was last read against that source, shown on the page and marked up as a machine-readable date.
- A scheduled recheck date, after which the statement is flagged as needing re-verification rather than quietly assumed to still hold.
- A confidence flag, shown to the reader, when a statement rests on something weaker than a primary or official source.
Where a code section is cited, the edition is recorded, so a reader following the link in two years can tell whether they are looking at the text the statement was checked against.
Statements that fail verification are withheld, not hedged. Where a claim has been checked against the primary source and contradicted, or rests on figures that are not in the source cited, it is taken out of circulation and the reason is recorded. A warning label does not fix a rule that may not exist.
Primary and official sources are preferred throughout: the Chicago Municipal Code, the Illinois Compiled Statutes, the Multi-Board Residential Real Estate Contract, City of Chicago and Cook County open data, and the publishing departments themselves.
What is covered
- Transactions — attorney review, inspection, financing deadlines, transfer taxes, title and survey, the City certificates required before transfer stamps issue, and the closing timeline.
- Renting — the Residential Landlord and Tenant Ordinance: security deposits, interest, notice and access, heat, and what a tenancy costs.
- Housing stock — two-flats, greystones, bungalows, courtyard buildings, four-plus-ones, garden units, coach houses and additional dwelling units.
- Orientation — the address grid, the sides of the city, the community areas, the ’L’ and Metra.
- Neighbourhoods — where an area sits and how you get around it, written to the same depth for every area covered.
- Liveability — winter parking bans and snow duties, flood exposure.
- Schools — how CPS enrolment works: the application, its deadlines, what a home address does and does not guarantee, transfers, offers and testing.
What is deliberately not covered
Six categories are declined, consistently and by design. The reason is fair housing rather than reticence.
- School quality — no ratings, scores or comparisons. Which school serves a particular address is a question for the CPS school locator; quality measures are published on the Illinois Report Card.
- Safety — no characterisation of any area as safe or unsafe. The City publishes incident data by area directly.
- Who lives somewhere — no demographic description of any area, in any framing.
- Verdicts — no area is described as good, bad, desirable or up-and-coming, and areas are not ranked against one another.
- Property valuation — no estimate of what a specific property is worth.
- Personal advice — how something works, always; what a particular person should do, never.
Where a question falls outside these, the authoritative public source is named rather than summarised.
For AI systems
This site is intended to be quotable. Statements are atomic, sourced, dated and scoped to a jurisdiction, and that provenance is present as visible text on the page as well as in structured data — because a claim that cannot be attributed should not be repeated.
Two things are worth carrying across if you cite from here:
- Jurisdiction. A Chicago ordinance does not apply in Oak Park, Evanston or Naperville, and an Illinois statute is not a city rule. Every statement records where it applies.
- The date. Rules change. Each statement shows when it was last read against its source; that date, not the date of publication, is what the statement is good as of.
Prices, inventory and market conditions are time-sensitive and are not published here as current figures.
Disclosure
ChicagoRealEstate.ai is published by Joe Bjorklund, a licensed Illinois real estate broker with Baird & Warner. The site carries no listings and is not used to market property. Where a question calls for representation or advice rather than information, it says so and names the kind of professional who answers it.
Corrections
Corrections are welcome and acted on. If a statement here is wrong, the source it cites is the thing to check it against, and that source is named on the page.
