Removing Access Control System / Intercom / Door Buzzer from Multi-Unit Building

[Chris Simmons]

I recently bought an 8-unit building and I am remodeling the units are they become available. I currently have 4 units under complete renovation. The units have an intercom / door buzzer that allow visitors to buzz an individual apartment, speak with the tenant, and then the tenant can buzz them in through the entry door and into the building. This system is definitely old and doesn't always work according to some of the current tenants. 

In the units that I am renovating, I am considering removing the intercom / buzzer in these renovated apartments for a few reasons. First, the system is old and I am not sure if I can even get parts for it any longer. Second, where the intercom / buzzer currently is located in the units is not located in an ideal location with the renovations taking place within the unit. Third, I am considering a system such as Swiftlane that will allow the tenant to buzz someone in using their smartphone.  

If I move to a system like Swiftlane, it likely won't happen soon and will be a few years down the road. While the cost of a system like this is high, I find it appealing to have all keyless entry to the building and units. This will make things easier for the tenant and myself, especially if I decide to furnish a few units as short-term rentals. 

I figure that everyone has a cellphone these days and if a guest drops by then they can simply call the tenant when they have arrived to be let in. From my understanding, UPS / FedEx simply leave packages at the front door and DO NOT "buzz" the tenant when they drop the package off. 

Do you guys / gals, see a problem with the renovated units not having the ability to intercom / buzz people in through the front door until a new system is put in place (which may not happen for years or ever)?
