You’re probably going to be repainting the interior of the house prior to moving a tenant in. You should also be thoroughly cleaning it. The biggest problem areas will be chipped or peeling paint around windows. If you don’t have that, and you clean well, you should pass.
The way the lead risk reduction inspection works is that you have to pass an exterior inspection. If there is any chipped paint anywhere, you fail and do not get to do dust samples.
If you pass the exterior inspection, the next step is dust samples. They do a dust sample from the floor of small area of each room and test that sample for lead. If the amount of lead found in that sample is above a certain threshold, you fail and have to redo that specific room only. You do not have to retest every single room if only one or two rooms fail. They don’t go around and scrape off paint on the inside and test that. It’s a small area of the ground that they test. If you make sure that your house is free of dust and debris and you use the cleaning products the EPA specifies (ie simple green) you’ll be fine.
I haven’t done the lead free inspection yet. If you go this route, you don’t have to recertify at every tenant turn. I have heard this is more expensive and can be difficult with the older homes in Baltimore city.
