If you are buying or selling a home in Union, you are working in the governmental and commercial heart of Franklin County, and the county-seat, where nearly two centuries of construction sit side by side. Union's housing stock runs from historic bungalows near the courthouse square, to mid-century ranches on the established hillsides, to the newer subdivisions that have absorbed the fastest population growth in the county. Each era carries its own inspection priorities that a thorough professional evaluation must address.
At Tech Inspect Home Services LLC, we provide complete, technology-driven home inspections for buyers, sellers, and homeowners throughout Union, MO (63084) and the surrounding Franklin County communities. We serve Union at flat-rate pricing with no mileage surcharges, and we include thermal imaging on every inspection at no additional charge.
Union, MO Housing Insights
Union has grown from a 19th-century Bourbeuse River mill town into Franklin County's seat of government and one of its fastest-growing communities. That growth layered new construction on top of a historic core — which is exactly what makes Union an inspection-intensive market, and a rewarding one for buyers who approach it with professional guidance.
Pre-1940 Historic & Downtown-District Homes
Original neighborhoods around the courthouse square and Union's historic downtown. Expect fuse boxes or older electrical panels, galvanized plumbing, aged roofing, and original plaster walls. Thermal imaging and 4-Point Inspections are strongly recommended. Insurance carriers typically require 4-Point documentation on homes of this age.
1940's - 1980's: Mid-Century Ranches & Split-Levels
Established hillside neighborhoods surrounding Union's core. Solid construction on mature lots, but HVAC, roofing, and water heaters are commonly at or past service life. Electrical panels from the 1970s–80s warrant evaluation. Our complete inspection documents every system in detail.
1980's - 2000's: Established Subdivisions
Active resale inventory with generally better mechanical condition. Roofing and HVAC in this range are approaching their replacement window. Additions and remodeling work completed without permits are common findings. A full buyer's inspection is recommended before any offer.
2000's - Present: Newer Builds & Growth Subdivisions
Union has posted some of the strongest residential growth in Franklin County, producing newer subdivisions on the city's edges. These homes still warrant a full inspection. Homeowners within the first year of a new build should schedule an 11-Month Warranty Inspection before builder coverage expires.
Rural / Acreage: Farms & Outbuilding Properties
Properties surrounding Union with barns, outbuildings, and acreage — including parcels along the rural edges that qualify for USDA financing. Well and septic systems are common; separate well water and septic testing is recommended as part of complete due diligence. Our Drone Roof Inspection provides safe, complete coverage of home and outbuilding rooflines.

Union, MO Neighborhoods & Property Areas
Union's neighborhoods reflect the city's development from a river-valley county seat into a growing Franklin County hub. Each area carries distinct inspection considerations.
Historic Downtown & Courthouse District:
The neighborhoods rising above Union's core — developed largely from the 1940s through the early 1980s — offer mature trees, larger lots, and long-term owner stability. Ranch-style and split-level homes dominate. Inspection priorities center on aging mechanical systems, roofing condition, and structural modifications made over decades of ownership. Our complete buyer's inspection produces a clear picture of near-term obligations before closing.
Established 1980's & 1990's Subdivisions:
Union's residential growth through the 1980s and 1990s produced subdivisions that now represent some of the city's most active resale market. Homes here are generally in better condition than older properties, but mechanical systems are commonly at or approaching the end of their service life. A complete buyer's inspection provides the documentation needed to evaluate condition and negotiate appropriately before closing.
Newer Growth Subdivisions & the US-50 Corridor:
Newer residential development on Union's edges offers modern construction for buyers who prioritize updated systems. Buyers in newer builds within their first year of ownership should schedule our 11-Month Warranty Inspection before the builder warranty expires. Pre-drywall inspections during construction remain the most valuable inspection for buyers of brand-new builds in this corridor.
Bourbeuse River Corridor & Valley Properties:
Properties in and around the Bourbeuse River valley require careful inspection attention to drainage, basement and foundation moisture management, and roofing condition on homes exposed to significant weather. Our Drone Roof Inspection provides complete, safe coverage of any roofline in this area.
Rural Acreage & Outbuilding Properties Near Union:
The land surrounding Union includes rural residential properties, small farms, and acreage parcels — many along the rural edges that qualify for USDA financing. Properties with barns, workshops, or outbuildings benefit from our Drone Roof Inspection for safe evaluation of every roofline. Well and septic systems are common; buyers should plan for separate well water testing and septic evaluation as part of complete due diligence.

What Buyers Should Know
Union, Missouri (ZIP 63084) sits in the Bourbeuse River valley roughly 50 miles southwest of downtown St. Louis, with US Route 50 running through the city and Interstate 44 about five miles to the east. As the county seat of Franklin County, Union is the region's governmental and commercial hub — combining a walkable historic downtown, strong local industry, river and outdoor recreation, and easy reach into Missouri wine country.
Union's German immigrant heritage shaped both its early architecture and its culture, and German surnames and building traditions remain common throughout the city and surrounding area. The community traces its civic history to the 1820s, when Union was founded in 1826 and designated the Franklin County seat in 1827.
County Seat & Historic Downtown: Union is home to the Franklin County Courthouse and serves as the county's center of government and commerce. Its historic downtown district preserves a walkable core of 19th- and early-20th-century commercial architecture.
Bourbeuse River & Outdoor Recreation: The Bourbeuse River gives Union direct access to canoeing, kayaking, and fishing, and nearby Robertsville State Park offers camping, hiking, and river access. River and valley recreation is a consistent quality-of-life draw for buyers relocating from the St. Louis metro.
Missouri Wine Country & German Heritage: Union sits within Franklin County's stretch of the Missouri Rhineland, the German-heritage wine region along the Missouri River corridor. Franklin County wineries and scenic river-valley drives are minutes from the city.
Union R-XI School District: Union High School (home of the Wildcats) and the Union R-XI School District serve the city and surrounding areas, and draw positive recognition from families relocating from the broader St. Louis region.
Franklin County Museums & Civic Landmarks: The Franklin County Veterans Museum, housed in the historic courthouse, and the Franklin County Historical Society Museum on East Locust Street anchor Union's role as the county's civic and cultural center.
Commute via US-50 & I-44: US Route 50 runs directly through Union, with Interstate 44 about five miles east and Missouri Route 47 leading north to Washington. Union is roughly 50 miles from the St. Louis metro, giving commuters two highway corridors toward the region.
WHY HIRE US
Why Choose Tech Inspect Home Services LLC?
Union's housing market demands an inspector who can move between a century-old home near the courthouse square and a rural acreage property with a barn and a private well outside the city limits. The property types, construction eras, and inspection priorities are genuinely varied — and a one-size approach does not serve Union buyers well.
Same-Week Scheduling — Including Weekends
Real estate contracts don't wait. We offer same-week availability throughout Union and Franklin County so your transaction stays on schedule without cutting corners on the inspection itself.

No hidden fees. Whether you're in downtown Union or on rural acreage outside town, you pay the same fair flat rate based only on square footage. See our Current Pricing without needing to call.
