Combining Apartments In NYC: The Two Factors That Determine Cost & Timelines

Identifying conditions and requests that determine costs and timeline for an NYC apartment combination.

Although not always considered, apartment combinations in NYC are one of the most efficient routes for renovating in Manhattan or Brooklyn. Yet, there’s often a misconception that adjoining two units takes significantly more time and cost than a standard renovation. Not always so. 

Ultimately, the timeline and cost of combining two apartments depends on the scope of your renovation and is determined by two main factors:

[#Factor-1]Factor 1) Extent Of Floor-Plan Reconfiguration[#Factor-1]

If you're combining two apartments where, for the most part, the overall space plan is going to remain very close to the current configuration, turning two units into one cohesive living area requires two bare essentials:

  • Capping one of the kitchens 
  • Creating an entry between the two apartments

Those two updates constitute the legal definition of an apartment combination and also present a best case scenario. Most apartment combinations in NYC are not that straightforward. Quite the contrary. Most of the time joining two apartments is extremely complex, because two layouts rarely blend properly without adjustment. For a logical flow to the expanded home, you're essentially forced into moving various walls and configuring a newly-combined floor-plan. 

Here comes the next domino. Moving the walls has potential to open up Pandora's box - because now you're rewiring the space. Now we're potentially bound by restrictions that govern wiring in the building. The electrical overhaul, in and of itself, is a significant undertaking. 

Bottom line, the more adjustments to the floor plan-plan, the longer and more costly your apartment combination.

[#Factor-2]Factor 2) Pre-Existing Site Conditions[#Factor-2]

Beyond the likely floor-plan reconfiguration and subsequent electrical work, pre-existing site conditions can also have strong ramifications on an apartment combination in NYC. 

For instance, are the floors the same throughout? Are they the same level? What about ceiling heights? Do wall conditions pair properly? Are you planning on moving a bathroom, kitchen, or laundry room to a former “dry” area (EX: living room) in a building where wet over dry restrictions could prevent the move? If these core aspects of the two adjoined apartments are not aligned favorably, expect higher costs and a longer timeline.

Are apartment combinations complex? More often than not, yes. Can they be expensive? Sure. However, when compared with attempting to buy a new apartment twice the size in a new part of town and potentially uprooting your life, the benefits are clear.
