Fritz v. Warthen

Why This Case Matters

Fritz v. Warthen created what is now known as the “Fritz defense” – one of the most important tenant protections in Minnesota law. The case held that the statutory covenants of habitability enacted by the Legislature in Minn. Stat. § 504.18 are mutually dependent with the tenant’s covenant to pay rent. This means a landlord who fails to maintain habitable conditions cannot evict a tenant solely for withholding rent in response.

The Facts

Around August 1, 1971, Robert and his wife began renting a one-bedroom apartment at 709 Portland Avenue in St. Paul on a month-to-month basis for $85 per month. After moving in, they discovered repair and maintenance problems that interfered with their use of the apartment. They notified the landlord and requested repairs, but the landlord made no corrections. In response, the Warthens withheld $35 of their February 1972 rent. The landlord filed an unlawful detainer action to evict them for nonpayment.

What the Court Decided

The Supreme Court held that the statutory covenants of habitability under Minn. Stat. § 504.18, subd. 1 – which require landlords to keep residential premises in reasonable repair, fit for their intended use, and in compliance with health and safety laws – are mutually dependent with the tenant’s obligation to pay rent. The court did not create a new common-law implied warranty; instead, it enforced the existing statutory mandate enacted by the 1971 Legislature. Because the covenants are mutually dependent, a tenant may assert the landlord’s breach of the habitability covenant as a defense to an eviction for nonpayment of rent.

What This Means for You

• The “Fritz defense” protects tenants: If your landlord has failed to maintain your home in compliance with health and safety laws, you may have a defense if the landlord tries to evict you for nonpayment of rent. This is a statutory right under Minn. Stat. § 504.18 (now codified in Chapter 504B).
• You must notify your landlord first: Before withholding rent, notify your landlord in writing about the specific repair problems and give reasonable time to fix them. Keep copies of all communications.
• Document everything: Take photos, save emails and texts, and keep records of every request for repairs. If you end up in court, your documentation will be critical to establishing the Fritz defense.
