An overbuilt building is one that exceeds the floor area ratio (FAR) allowed by current zoning. This occurs for two main reasons:
- A building was constructed before the 1961 zoning resolution, which introduced FAR as a mechanism to manage a building’s bulk
- A building was constructed according to one zoning district and a down zoning occurred after its construction (ex. a building was constructed using all permitted FAR in 2000 in an R9 district – which allows an FAR of 7.52 – and that R9 district was rezoned in 2010 to an R8 district – which only allows an FAR of 7.2 – so the building is overbuilt by 0.32 FAR)
Generally, the fact that a building is overbuilt is of significance because it translates to a low likelihood that the building will be modified in the future. This is because, if it were demolished the building could only be rebuilt to the FAR permitted by the current zoning district. So the costs associated with demolishing a building and then constructing a building will less square footage generally isn’t economically advantageous for the property owner.
