The Legal Power of Affirmative Defenses
An affirmative defense is an independent legal justification that, if proven true by the tenant, legally defeats the landlord's claim for possession even if the landlord's allegations (such as non-payment of rent) are factually true.
Common Statutory Affirmative Defenses
- Breach of Implied Warranty of Habitability: Codified in Green v. Superior Court (California) and Javins v. First National Realty Corp. (D.C.), tenants have an absolute right to safe, decent housing. Serious code violations reduce the rental value, and in many states, no rent is owed until repairs are made.
- Statutory Retaliation: Landlords cannot evict a tenant because the tenant joined a tenant union, complained to city building inspectors, or exercised statutory repair-and-deduct remedies. Most states maintain a statutory presumption of retaliation if the eviction is filed within 90 to 180 days of protected activity.
- Waiver by Acceptance of Rent: If a landlord serves a notice to quit and subsequently accepts even a partial rent payment without an express reservation of rights, the notice is legally voided.
