Before we closed on the purchase of our lot we had an Big East Environmental check the existing home for asbestos and we also had them check to see if there was a buried oil tank (the existing home was on city gas, but it was not much extra to check for underground storage tanks so tacked that on to the scope). Big East found some asbestos so that would have to be abated before the home could be demolished (115 sqft of linoleum tile, 20 sqft of bathroom tile, and 40 sqft of roof flashing). Not a big deal, some cost and time, but no barrier to closing.
As we started the design process for the new home with the architect we discussed the demolition of the old home, and they “highly recommended” not doing that until a building permit was secured, in order to avoid unpleasant zoning changes. We did a little homework on zoning, I think I might have also stopped in to talk to the local planning & zoning people, and the new home was going to be larger and tighter to setbacks than the existing home, so we ignored the architect’s advice and proceeded with the demolition so that we could have things moving forward in parallel. For example, to conduct borings for soil tests we needed to have the demolition complete, and to design the foundation we needed the soil evaluation done. It also seemed to be hard or impossible to get liability insurance with a vacant (uninhabitable) home on the property, whereas vacant land would be covered under existing liability we already carried. We didn’t get our building permit until almost a year later, so glad we didn’t wait …
So shortly after closing on the lot we picked Terzian Trucking to do the demolition and engaged Homeguard Environmental to complete the asbestos abatement. Once the asbestos was removed Big East came back out to complete a final inspection and provided us with a Certificate of Visual Clearance and a copy of a notification they had sent to the CT Department of Health.
The demolition process in Norwalk is straight forward and probably typical. Before permitting the demolition you need to publish a notice in a local newspaper, notify your neighbors via certified mail, and post a sign on the property.
To get the demolition permit you also need a tax clearance certificate, disconnect letters for all utilities, sign off from the historical building people, asbestos clearance info, and the demo contractor needs to provide his license and proof of insurance. Surwilo Contracting handled sewer and water disconnects, coordinating with the Norwalk DPW and the local water utility. Water main was on the other side of the street, they went in through lawn and disconnected the old 3/4 line (maybe iron?) at the main. Sewer was disconnected pretty close to the street ROW line in our yard, they ran a video camera in to check remaining lateral out to the main and then capped it. 6″ PVC was in good shape so all we would need to do is reconnect. For gas the utility, Eversource, removed the meter and disconnected the line at the main, no cost to us. Electric the utility came out and removed the meter and the overhead line.
The actual demo was completed in just a few hours. No basement but a few concrete footings that were a little work to get out. Building department came out to take a look and then we received a Certificate of Compliance to close out the demolition permit.
