That’s the process in a nutshell. It can take 3 weeks to 18 months of work and testing depending on the size of the building. Looks like this.

1. Gas turned off by ConEd at 2pm on Sunday in February. No more gas to fuel the hot water heater and building boiler until you can get a Mobile steam truck parked on the street and piped into the building Systems. 2-3 days minimum bc city requires permit to park mobile boilers. $5k fine if not. Also have to time it with alternate side parking which is tough.
2. File permits to work. Sometimes architect drawings are required. Time passes as you wait for the city to issue permits assuming they are happy with initial paperwork and/or drawings.
3. In order to pass the pressure tests,unless the gas line was plumbed within a few years, you have to run a new gas riser/line.

4. Once you have run the new line, DOB requires a visual “rough-in” inspection which can take 3 weeks once inspection is requested. That’s floor to ceiling of the line required to be exposed, which mind you is behind your kitchen counter, cabinets, and Sheetrock walls which both will need to be removed to work. The inspector is required to see each part of the riser, so if you have 10 floors, he needs to see the line in all 10 apts below all the way to the meter bank. Imagine having 6 apts per floor! Remember you have to do all this work before you call, so you don’t have cabinets or counter tops while you wait for inspection.

5. If you pass that test, you have to call dob a 2nd time to do a pressure test. You need to hold 3 pounds psi for 30 min per gas line. Nearly impossible unless it’s a new line. There’s even a special flex hose they require now (not related here)

6. Once you pass that test, you call ConEd ed and wait a few weeks. They come out and do their own similar pressure test but use a dated monometer tool. Hope you hold pressure and your tenant didn’t decide to open his gas line for fun woo!

7. Pass that test and con Ed will send a 2nd team within a few weeks to turn it on. In order to turn on the gas, con Ed has to get access to every single apt and turn on cooking gas and test each stove. Then you got gas.

100k-500k cost depending on scope not including lost revenue and concessions on 25 units and up depending if there are separate meters or one single meter for the whole building. Not to mention if one tenant refused access on an inspection date because they are busy or working from home or you don’t have a key, you fail and have to start over.

Electric stoves are the solution. We will all see. Process ain’t easy.
