Radon: Zone 1 — High Risk· State-level data

Columbus has a diverse housing market anchored by The Ohio State University, with older neighborhoods like Victorian Village, German Village, and Clintonville containing early 20th century construction alongside extensive post-war suburban expansion. German Village's brick rowhouses are a distinctive Columbus character, and masonry inspection concerns, including tuckpointing, lintel condition, and parapet flashing, are important in that housing type. Columbus's clay soils cause basement wall movement and foundation cracking in older construction. The city's freeze-thaw cycle is hard on masonry and exposed concrete. Older Columbus homes routinely have original cast iron drain lines, galvanized supply pipes, and original electrical panels. HVAC systems work significantly in both heating and cooling given Ohio's climate. There are 17 inspectors in the Columbus area.

Common Home Issues in Columbus, OH

Based on regional construction history and climate, home inspectors in Columbus frequently report these issues.

Radon Gas — Statewide High Riskhigh

Ohio has among the highest average indoor radon levels in the Midwest. Glacial till, limestone, and shale geology across the state contribute to elevated readings. Every Ohio county has documented elevated radon — testing is universally recommended.

Basement Water Intrusionhigh

Ohio's heavy clay glacial soils have poor drainage and create high hydrostatic pressure on basement walls. Block foundation construction common in older suburban housing frequently shows lateral bowing, step cracking, and seepage.

Knob-and-Tube & Aluminum Wiringhigh

Cleveland, Columbus, Cincinnati, and their older suburban rings have significant concentrations of pre-1940 knob-and-tube wiring. Aluminum branch circuit wiring is common in 1960s–70s suburban construction throughout the state.

Sewer Lateral Conditionmedium

Ohio's older cities have aging clay and cast-iron sewer laterals that are frequently cracked, root-infiltrated, or collapsed. A sewer scope inspection is strongly recommended for any home over 30 years old in the Cleveland, Columbus, or Cincinnati metros.

Foundation Issues on Clay Soilmedium

Expansive clay soils throughout central and northwestern Ohio cause differential settlement in both slab and basement homes. Settlement cracks at window corners and door frames are a common symptom.

Housing Age Profile — Columbus
