Environmental improvements brought by the legal interventions in the homes of poorly controlled inner-city adult asthmatic patients: a proof-of-concept study.

Objectives: Domestic contamination with mold, cockroaches, rodents, and dust worsens asthma severity. This violates warranty of habitability laws in most of the states, but patients often find it beyond their means to remedy their housing situation. We aimed to study the effect of a medical-legal collaborative intervention to force landlords into providing better living conditions for patients with poorly controlled asthma.
