Prospective Tenant Asking About Radon Testing

[Kathleen Sedita]

I'm the property manager for 196 units in Golden, Colorado (just outside of Denver). A prospective tenant has asked if we have ever done radon testing for their unit. I know we have not done radon testing since we took over management of the property 1.5 years ago. I haven't been able to get a solid answer from anyone with the ownership about previous years. No one seems to know if we have had it done or when. (It's a large company with thousands of doors across the country. They aren't going to dig up those records for one prospect.) The property was built in 1996 and 2000. They are all 2-story townhome style apartments. No basement units. Bedrooms are on the second floor of the units.

My question is, what do most people do about radon testing? And what is the best way to reply to this prospect's question? I know how I would handle this if it were one of my tenants in my personal rental properties, but things are different with these large companies and it is not in our budget to do testing even though it's pretty cheap. Plus, with Fair Housing, if we were to test one unit we would then have to test all 196 units and there is where the huge cost is.
