[quote=Anonymous]Basement dig-outs in DC row houses is very common. That said, I'd be very nervous about a neighbor wanting to do this work. Structural damage can happen to your shared wall. That wall is supported by a shared footer that was designed for the load it has to support and transfer to the dirt below. With a dig-out, their will be concrete underpinning that adds a considerable amount of extra weight that must be supported by the soil below. Settlement is a real concern. Drainage is also a big issue. I've seen dig-outs where they tapped into some unexpected underground water flow that needed to be managed. DCRA is very strict on the permitting process. If you can afford it, you may want to hire a structural engineer with a PE to review the plans and offer his opinion on how this may affect your property. That said, there is probably nothing you can do to prevent them from going forward, once their permitting is approved.[/quote]
