Accessibility In Existing Buildings

Whenever space is altered in an existing building, the new building elements provided must comply with New Jersey Barrier Free requirements.
In addition, New Jersey’s Uniform Construction Code requires “… an accessible path of travel … be provided up to the point at which the cost of providing accessibility is disproportionate to the cost of the overall … project; a cost is disproportionate if it exceeds 20% of the cost of work.”
This means that in addition to providing accessibility for the new work, 20% of the construction cost must be provided on top of the cost of the new work.
In order to determine the disproportionate cost, the following items should first be deducted from the overall project cost:
New windows, hardware, operating controls, electrical outlets, signage, mechanical systems, electrical systems, installations and alterations of fire protection systems, abatement of hazardous materials, repair or installation of roofing, siding or other exterior wall façade.
Once these items have been deducted from the project cost, the resulting number (cost) should be multiplied by 0.20. The product is the additional cost which must be applied in order to provide additional accessibility in other parts of the building’s exterior and/or interior accessible route.
It should be noted that all accessible deficiencies in a building do not have to be corrected during a given project. The only criteria that must be met are new work must comply with accessibility requirements and the additional 20% cost as described above must be applied in providing an accessible route.
