Meet a Missouri-licensed mental health professional by phone or video. If you're approved, your signed ESA letter arrives in 10-15 minutes.
O'Fallon is the largest city in St. Charles County and one of the fastest-growing St. Louis suburbs.
For O'Fallon renters, the key document is a letter from a mental health professional licensed in Missouri. It supports a reasonable accommodation request so a no-pet policy, pet rent or a pet deposit can be waived.
With roughly 96,100 residents, O'Fallon in St. Charles County is Missouri’s seventh-largest city. Renters across WingHaven, Dardenne Prairie, St. Peters, Lake Saint Louis and Wentzville rely on the same fair housing protections, whatever the building or landlord.
Missouri law makes it a crime to misrepresent any animal as an assistance animal to get a housing accommodation under the federal Fair Housing Act, including emotional support animals, or to lie to a health care provider to get the documentation (RSMo § 209.204). Housing discrimination complaints can be filed with the Missouri Commission on Human Rights or with HUD. For the details, read our Missouri ESA law guide.
