Question 1

Do landlords in Ohio have to test for radon?

Accepted Answer

No. Ohio's radon law, ORC Chapter 3723, licenses testers and mitigators but does not require landlords to test rentals. Local health districts such as Delaware's note they have no statewide authority over indoor air in homes. Tenants can test their own unit with a kit. For an owner, the practical case for testing is simple: ground-contact units carry the exposure, results are cheap to get, and a high number is better found by the owner than by a tenant. ODH recommends retesting multifamily buildings every five years and houses every two. Mitigating a rental works like any home, done by an Ohio-licensed mitigation contractor, with the closeout package kept for the next tenant or buyer. A tenant who finds a high result should send the report to the owner in writing; free kits are available through ohio.radon.com. For obligations under a specific lease or a local housing code, ask a lawyer rather than relying on general guidance. See radon in apartments and condos.

Question 2

Can apartments and condos in Columbus have radon?

Accepted Answer

Yes, mainly units in contact with the ground: garden-level and first-floor units and those over a crawl space or basement. Upper floors usually read lower. The Ohio Department of Health recommends retesting multifamily buildings every five years. Central Ohio has plenty of ground-contact rental stock: garden units in older buildings near Ohio State, walk-ups in the Short North and Italian Village, and slab-on-grade townhomes across the suburbs. Ohio's measurement protocol treats multifamily buildings separately from houses, and testers must file their own procedures for them with ODH, while a single condominium unit is measured like a home. Large buildings are mitigated under a different national standard, ANSI/AARST SGM-MFLB-2023, rather than the single-family one. A tenant can test a unit with a kit, but mitigation involves the building, so it belongs to the owner or the association. See landlords and radon and our commercial and multifamily service.
