HB 451 Delaware House · 153rd General Assembly (2025-2026)

AN ACT TO AMEND TITLE 6 OF THE DELAWARE CODE RELATING TO FAIR HOUSING AND DISPARATE IMPACT LIABILITY.

Summary
This Act clarifies that Delaware’s Fair Housing Act (Chapter 46 of Title 6) prohibits housing practices that have a discriminatory effect, commonly known as “disparate impact,” even in the absence of discriminatory intent. The Act codifies a burden-shifting framework consistent with federal fair housing jurisprudence and regulations and with laws adopted in other states, including California and Massachusetts. Under this framework: 1. A complainant must show that a housing policy or practice causes or predictably will cause a discriminatory effect on a protected class. 2. A respondent may defend the practice by demonstrating that it is necessary to achieve a substantial, legitimate, nondiscriminatory interest. 3. A complainant may still prevail by showing that the interest could be served by a less discriminatory alternative. The Act applies to rental policies, sales practices, lending and appraisal practices, occupancy standards, criminal history screening, and zoning or land use decisions to the extent permitted by law. It clarifies that statistical evidence may be used to establish disparate impact and that proof of discriminatory intent is not required. The Act aligns enforcement with existing remedies and procedures under Chapter 46 of Title 6 and preserves the authority of the Division of Human and Civil Rights under Title 31. It does not require quotas, does not invalidate lawful occupancy limits, and does not impose liability where a practice is required by federal law. This Act is intended to be interpreted consistently with, but not limited by, the federal Fair Housing Act and provides equal or greater protection under Delaware law.

What changed between versions

HA 1 to HB 451 Bill Text · 8 edits
MODERATE
The final enacted version of HB 451 restored the full scope of the disparate impact framework that House Amendment No. 1 had attempted to narrow. HA 1 would have removed algorithm-related language, land-use provisions, and enumerated covered practices, but the final bill text retains all of these elements. The enacted law establishes a detailed burden-shifting framework for proving discriminatory effect in housing cases without requiring proof of intent, applies to algorithms and automated decision-making systems, and explicitly covers zoning and land use decisions.
Scope change
The final enacted version is broader than what HA 1 would have produced. HA 1 sought to narrow the bill by removing algorithm-related language, land-use provisions, and enumerated covered practices, replacing them with a single general applicability sentence. The final bill retains all of these elements, meaning the disparate impact framework explicitly reaches automated decision-making systems, zoning and land use decisions by political subdivisions, and a wide range of specific housing-related practices.
SCOPE

The final bill explicitly covers practices that rely on algorithms, automated decision-making systems, risk assessments, or data-driven models, stating they are subject to disparate impact liability even if inputs or methodology are facially neutral. HA 1 had removed this language.

The final bill applies to public and private land use decisions affecting housing opportunities, availability, or access, and explicitly subjects political subdivisions exercising authority under Title 9 or Title 22 (zoning and planning) to the chapter. HA 1 had removed land-use provisions.

The final bill enumerates specific covered practices including sales or rental practices, lending/underwriting/appraisal practices, occupancy standards, criminal history screening policies, third-party outsourced screening, and land use decisions. HA 1 replaced this list with a single general sentence referencing all discriminatory housing practices as defined in section 4602.

A policy is not shielded from liability solely because it is authorized by another state or local law unless compliance with that law is mandatory. However, a practice required by federal statute or regulation does not constitute a violation.

DEFINITION

New definitions added to section 4602: 'Discriminatory effect' (a practice that actually or predictably results in disparate impact on a protected class or perpetuates segregation), 'Disparate impact' (a facially neutral policy that disproportionately and adversely affects a protected class), and 'Less discriminatory alternative' (an alternative serving the same legitimate interest with less discriminatory effect).

REQUIREMENT

A three-step burden-shifting framework is codified: (1) complainant proves a practice caused or predictably will cause discriminatory effect, (2) respondent proves the practice is necessary to achieve substantial legitimate nondiscriminatory interests, (3) complainant may still prevail by showing a less discriminatory alternative exists.

ENFORCEMENT

The Division of Human and Civil Rights is granted authority to promulgate regulations to implement the disparate impact section. The section supplements existing enforcement authority under section 4611 and remedies under section 4613.

TECHNICAL

The bill takes effect 90 days after enactment and includes a severability clause.
