A Landlord’s Guide to Renting in Franklin County, Missouri
Franklin County occupies a distinctive position in the Missouri rental landscape: it is simultaneously a St. Louis metropolitan exurb, a collection of independent small towns with their own economic identities, and a stretch of rural Missouri Rhineland wine country that draws visitors from across the region. That triple identity creates a rental market with genuinely different sub-markets within its 922 square miles, and landlords who understand which sub-market their property occupies will make better decisions about pricing, marketing, and tenant screening than those who treat the county as a single homogeneous entity.
The I-44 Eastern Corridor
The eastern edge of Franklin County — particularly the communities of Pacific, St. Clair, and the unincorporated areas bordering St. Louis County — functions economically as a true St. Louis exurb. Interstate 44 runs through this corridor, providing direct highway access to St. Louis, and the area attracts households who want rural Missouri living at significantly lower housing costs than the St. Louis suburban ring offers. Tenant profiles here closely mirror those of Lincoln County or Jefferson County’s STL exurban tier: dual-income households, commuters, tradespeople who work in the metro, and retirees who moved out from the closer-in suburbs. Income verification should account for commuting costs, which are real and meaningful at this distance from St. Louis. Properties in this corridor tend to command the county’s highest rents and attract the most financially stable tenant pool.
Washington and the River Towns
Washington is the county’s largest city at approximately 14,000 residents and functions as the commercial hub of the county’s mid-section. Located on the Missouri River, Washington has a historic downtown, a mix of manufacturing and retail employment, and a small-town character that attracts long-tenancy residents who have little interest in commuting to St. Louis. The city’s tenant pool is primarily local workforce: manufacturing employees, healthcare workers, retail and service staff, and the various tradespeople who support the area’s residential and agricultural economy. Union, the county seat with approximately 10,000 residents, has a similar character — a working small town with stable local employment and modest but predictable rental demand.
Sullivan and the communities along US Highway 50 to the west of Union serve the county’s rural interior and the edge of the Missouri Rhineland wine region. The wine country context brings seasonal tourism and the hospitality economy that accompanies it, but this has limited impact on the long-term residential rental market. What it does create is a small market for short-term and furnished rentals near the winery corridor, which some landlords have developed into a supplementary income stream, though this requires careful licensing and tax compliance under Missouri’s short-term rental framework.
The 20th Judicial Circuit in Union
All Franklin County evictions file with the 20th Judicial Circuit at the Franklin County Courthouse, 401 East Main Street, Room 100A, Union, MO 63084. The civil division phone is (636) 583-7366. Court hours are Monday through Friday, 8:00 a.m. to 4:30 p.m. The 20th Circuit serves Franklin County exclusively. From eastern Franklin County communities like Pacific, the drive to Union is approximately 35 to 40 miles, so budget travel time for in-person filing and hearing appearances accordingly. LLCs and business entities must retain a licensed Missouri attorney for all eviction proceedings.
An Older County
Franklin County’s median age of approximately 44 years is among the highest of any Missouri county its size. This reflects the county’s established, owner-dominated residential character — 18.6% of residents were 65 or older at the 2020 census, a proportion that has likely continued to grow. For landlords, this demographic reality has practical implications. Older tenant pools tend toward longer tenancies, lower eviction rates, and more stable payment patterns. They also tend to have fixed or retirement incomes that require different income verification approaches than working-age W-2 earners. When verifying income for retirees, Social Security award letters, pension statements, and bank statements showing regular deposits are the appropriate documentation rather than pay stubs. The Missouri income verification framework for rental applications does not change based on the source of income, but the documentation does.
