Of course he will need them not to use any stairs for a week because you don't want them walking through a construction zone but it might be only a few days for a stairway and then most of the work is on your level.   

The Premises are comprised of Tenant's dwelling unit, as well as any common areas, including, but not limited to entryways, patios, yards, community rooms, hallways, basement, laundry room, stairways, balconies, decks, and garage.D) Tenant to Promote Smoke-free Policy and to Alert Landlord of Violations.

This was an open and large apartment where every unit had a balcony or in my case patio that led to the yard and the doors were all in an open stairway. 

The HVAC for the first floor unit supplies conditioned air into the common hallway/stairway.

I'm trying to envision how that would even work or what it would look like...Yes here 2 exits to the 'ground' are required so we were lucky to have the 2 stairways in place from days of old.

i heard there are a restriction that i need to have a basement entrance from the first floor (stairway, which i want to remove), but could not find any official guidance on that, and could not get an answer on this question in the zoning dept.

Good morning all,I am looking to get my entry way & stairway repainted & new carpet on the stairs.

Basically a stair way up by, building, flipping, managing and renting.  

I did do some things upstairs.. added some new carpet all throughout the upstairs, had some insulation blown in, and the ceiling tiles painted as well as the stairway walls.

Does a permit need to be pulled for a single stair way?
