I took the photo above this past Saturday. What you are looking at is a vacant property owned by IDS DC Inc (according to tax records). During the housing boom they had sights on developing the property. They built four houses that were/are overpriced and not harmonious with the neighborhood. Then came the housing bust. I believe they just recently sold one house. The others still have for sale signs up. And this property is the graveyard for the foundation for the fifth house that was never built.
According to the information I found on the DCRA website, excessive overgrown vegetation is a direct violation of the "Nuisance Properties Abatement Reform and Real Property Classification Amendment Act of 2008". The area is prime for rodent infestation. Hopefully DCRA can track down the owner and get them to address the situation.
