From the mail bag:
"Love your vacant property blog. I have a question about 925 5th Street NW. Tony Cheng (the owner of the property) has removed the roof (it had a tree growing out of it anyway). The back of the property is secured by plywood. Drug users and homeless are using the building by pulling off the plywood and/or climbing over the plywood. This is clearly a violation. The building is not secure and I'm not sure that you can have a vacant building without a roof. What do I need to do to get this property properly reported as a nuisance, condemned, fixed, etc..."
