Chicago redlining was the practice, formalized by federal mapmakers in the late 1930s and enforced by private lenders for decades after, of denying mortgage credit to neighborhoods based on the race of the people who lived there. Huge stretches of the South and West Sides were graded “hazardous” and colored red on government maps, cutting Black Chicagoans off from the home loans that were building white middle-class wealth. The maps themselves stopped being drawn long ago, and the practice is now illegal under federal and Illinois law, but the financial damage compounded across generations. Property values, homeownership rates, and median incomes in the neighborhoods that were redlined in the 1930s still trail the rest of the city today.
How the HOLC Graded Chicago Neighborhoods
Between 1935 and 1940, the Home Owners’ Loan Corporation drew “Residential Security Maps” for more than 200 American cities, Chicago among them. Every neighborhood got one of four grades on a color-coded scale: green “A” for Best, blue “B” for Still Desirable, yellow “C” for Definitely Declining, and red “D” for Hazardous.1Mapping Inequality. Mapping Inequality Examiners looked at building age and condition, transportation access, proximity to parks or factories, income levels, and the racial and ethnic composition of the residents.
A red grade functioned as a dead zone for mortgage lending. Banks that consulted the maps either refused loan applications outright or charged sharply higher interest inside the red boundary. The Federal Housing Administration used the same risk assessments to decide which mortgages to insure, so a D rating shut residents out of the government-backed, low-interest loans that were driving suburban development. A property could be structurally sound and the applicant could have steady income; if the address sat inside a red zone, the money did not flow.
Which Chicago Neighborhoods Were Redlined
The HOLC maps painted vast sections of the South Side and West Side solid red. Bronzeville, the cultural and economic heart of Black Chicago, received a D rating on nearly every block. Douglas got the same. The area descriptions HOLC examiners wrote to accompany the maps left no ambiguity about what drove the grades. One warned that “unless various real estate protective associations are strong enough to restrict the colored people, ultimately they will spread over that territory east of Cottage Grove between 39th and 47th.”2Mapping Inequality. Mapping Inequality – Chicago Another described an “already negro-blighted district” and worried about what would happen “when so many of this race are drawn into this section.”
Appraisers pointed to overcrowding and building age as justifications, but their own descriptions treated race as the deciding factor. A block of solid brick homes with employed residents could still receive a D if Black families lived there. Those hard boundaries then told local banks exactly where to withdraw conventional credit.
Covenants, the FHA, and Contract Buying
The maps did not work alone. Racially restrictive covenants were private legal agreements filed with the Cook County Recorder of Deeds that barred property owners from selling or leasing to Black buyers. They spread block by block until, by some estimates, roughly 80 percent of Chicago homes were covered. Typical language stated that no part of the property could be “sold, given, conveyed or leased to any negro.” Chicago-based real estate industry leaders promoted these agreements nationally.
The federal government reinforced the private ones. The FHA underwriting manual listed restrictive covenants as a factor in evaluating neighborhood “protection from adverse influences” and instructed appraisers to collect data on residents’ “race” and “color.”3HUD User. Federal Housing Administration Underwriting Manual HOLC flagged Black neighborhoods as hazardous, the FHA refused to insure mortgages there, and covenants blocked Black families from buying into neighborhoods where financing was available. The loop was closed.
Two Supreme Court cases with Chicago roots began pulling it apart. In 1940, the Court held in Hansberry v. Lee that Carl Hansberry, a Black real estate broker who bought a home on the South Side in defiance of a covenant, was not bound by a prior court decree enforcing that covenant.4Justia. Hansberry v Lee, 311 US 32 (1940) Eight years later, Shelley v. Kraemer held that while private racial covenants did not themselves violate the Fourteenth Amendment, state courts could not enforce them, because doing so would put government power behind racial discrimination.5Justia. Shelley v Kraemer, 334 US 1 (1948) After Shelley, covenants stayed in Chicago deeds but became legally unenforceable.
Blocked from conventional mortgages, Black Chicagoans became targets for a parallel exploitative market. White speculators bought homes in transitioning neighborhoods at market price and resold them on installment contracts at dramatically inflated prices. Under a contract sale, the buyer put down money and paid monthly installments, often at high interest, but earned no equity until the final payment. Missing even a single payment meant losing the home and every dollar already paid. The speculator kept the property and resold it to the next family on the same terms.
By the late 1960s, the practice had drained enormous wealth from Black Chicago. A group of middle-aged Black homebuyers on the West Side formed the Contract Buyers League and, from 1968 to 1971, organized payment withholding, picketed speculators’ offices, resisted evictions, and pursued litigation in federal court. Most contract buyers never recovered what they had overpaid.
The Lasting Financial Damage
The consequences did not end when the maps stopped being drawn. Research by the National Community Reinvestment Coalition found that 74 percent of neighborhoods HOLC graded “Hazardous” eight decades ago remain low-to-moderate income today. In Chicago the pattern holds with striking clarity. South Side and West Side communities that were redlined in the 1930s still have lower homeownership rates, lower median incomes, and less access to conventional credit than neighborhoods that received green or blue grades.
Property values tell the sharpest story. Nationally, median home values in formerly “Best”-rated areas climbed roughly 231 percent between 1996 and 2018, reaching about $640,000. In formerly “Hazardous” areas, values rose only 203 percent, to about $276,000. The gap widens further in Chicago’s suburbs. Olympia Fields, a majority-Black community south of the city that ranks among the wealthiest and best-educated Black municipalities in the country, saw home values in the 2010s that had barely moved from 1990 levels. Nationwide, home values had actually declined since 2000 in nearly 20 percent of zip codes where most homeowners are Black, compared with just 2 percent in neighborhoods where Black residents were in the minority.
Homeownership is the primary vehicle for building family wealth in the United States, and families shut out of it for decades entered the post-civil-rights era with a fraction of the equity their white counterparts had accumulated. Depressed property values also mean a smaller local tax base, which translates into fewer resources for schools, infrastructure, and public services in exactly the neighborhoods that need them most.
The Laws That Now Prohibit Redlining
Redlining as originally practiced is illegal today. The Fair Housing Act of 1968, codified at 42 U.S.C. § 3605, makes it unlawful for anyone in the business of residential real estate transactions to discriminate in making loans, setting loan terms, or appraising property because of race, color, religion, sex, disability, familial status, or national origin.6Office of the Law Revision Counsel. 42 USC 3605 – Discrimination in Residential Real Estate-Related Transactions The Equal Credit Opportunity Act, at 15 U.S.C. § 1691, extends the same prohibition across all forms of credit, not just housing.7Office of the Law Revision Counsel. 15 USC 1691 – Scope of Prohibition
The Community Reinvestment Act of 1977 takes a different approach. Under 12 U.S.C. § 2901, banks have a “continuing and affirmative obligation to help meet the credit needs of the local communities in which they are chartered.”8Office of the Law Revision Counsel. 12 USC Chapter 30 – Community Reinvestment Regulators examine each institution’s record of lending to low- and moderate-income neighborhoods and use that record when the bank applies to open branches or merge. A poor CRA rating creates real obstacles to expansion. The Home Mortgage Disclosure Act at 12 U.S.C. § 2801 then requires lenders to publicly report the geography of their mortgage lending, giving regulators and the public the data to detect modern patterns of exclusion.9Office of the Law Revision Counsel. 12 USC 2801 – Congressional Findings and Declaration of Purpose
Illinois adds its own protections. The Illinois Human Rights Act at 775 ILCS 5/3-102 makes it a civil rights violation for any property owner, broker, or salesperson to refuse a real estate transaction, alter its terms, misrepresent availability, or use criteria that have the effect of discriminating based on race, color, religion, national origin, sex, disability, familial status, immigration status, or source of income.10Illinois General Assembly. Illinois Code 775 ILCS 5 – Illinois Human Rights Act, Article 3 The Act also prohibits blockbusting, the practice of soliciting property sales by warning residents that people of a particular race are moving in and values will drop. The Illinois Department of Financial and Professional Regulation examines state-chartered banks under a state Community Reinvestment Act that mirrors the federal one.
Reverse Redlining and Modern Enforcement
The newer version of the problem is not credit denial but predatory credit. Reverse redlining targets borrowers in predominantly Black or Latino neighborhoods for loans carrying inflated interest, excessive fees, balloon payments, or prepayment penalties that borrowers in white neighborhoods are not offered. Courts have held that reverse redlining violates the Fair Housing Act because discriminating in the “terms or conditions” of a residential loan on the basis of race is just as illegal as refusing the loan.6Office of the Law Revision Counsel. 42 USC 3605 – Discrimination in Residential Real Estate-Related Transactions Plaintiffs can show they are members of a protected class, qualified for the loan, received it on grossly unfavorable terms, and that comparable borrowers outside the class got significantly better terms. Statistical evidence of disparate impact will also support a claim. The 2008 subprime mortgage crisis hit formerly redlined Chicago neighborhoods with particular force, and much of the damage traced directly back to reverse redlining.
Federal enforcement has repeatedly reached Chicago-area lenders. In 2004, the Department of Justice charged First American Bank with intentionally avoiding the credit needs of residents and small businesses in minority neighborhoods. The complaint noted that not one of the bank’s 34 branches was located in a minority area and cited statements by bank officials indicating the lending practices were racially motivated. The case settled for $5.7 million.11U.S. Department of Justice. Chicago Bank Charged With Discriminatory Lending
More recently, the Consumer Financial Protection Bureau pursued Townstone Financial, a non-bank mortgage lender in the Chicago area. The CFPB alleged that between 2014 and 2017 only 1.4 percent of Townstone’s applications came from Black applicants and less than one percent came from majority-Black neighborhoods, both far below peer lenders in the same market. The CFPB also alleged that on a company radio show, Townstone employees made disparaging remarks about Black people and predominantly Black neighborhoods. After the Seventh Circuit ruled against Townstone, the company entered a consent decree and paid a $105,000 penalty. The case extended fair lending law’s reach to marketing conduct, not just lending decisions.
Efforts to Repair the Damage
Some Chicago-area institutions are now channeling investment into formerly redlined neighborhoods, though the resources deployed are dwarfed by the scale of what redlining took. The Cook County Land Bank Authority, which acquires and rehabilitates vacant and tax-delinquent properties, has sold nearly 2,400 properties since its founding, with more than 1,800 involving rehabilitation by local developers. The Land Bank explicitly ties its mission to correcting “historical wrongs such as redlining and discriminatory housing policies.”12Cook County Land Bank Authority. CCLBA 10-Year Impact Report It estimates that tens of thousands of homes near its rehabilitated properties have gained a combined $1.44 billion in value, and it offers an Equity Fund providing up to $20,000 toward down payments or closing costs for buyers purchasing a primary residence.
In 2021, Evanston became one of the first municipalities in the country to approve a reparations program tied directly to housing discrimination. The Local Reparations Restorative Housing Program grants qualifying Black households up to $25,000 for down payments or home repairs, funded by revenue from the city’s recreational marijuana tax. To qualify, residents must have lived in Evanston between 1919 and 1969 or be direct descendants of someone who did.
Whether investment on this scale can close wealth gaps that accumulated over nearly a century of institutional exclusion is an open question. The Cook County data suggests targeted rehabilitation can stabilize values in neighborhoods that redlining systematically stripped of capital. Closing the gap those maps opened is a longer project.
