CBC (2019) 11B-202.4
Path of Travel Requirements in Alterations, Additions and Structural Repairs.
When alterations or additions are made to existing buildings or facilities, an accessible path of travel to the specific area of alteration or addition shall be provided. The primary accessible path of travel shall include:
- A primary entrance to the building or facility,
- Toilet and bathing facilities serving the area,
- Drinking fountains serving the area,
- Public telephones serving the area, and
When the adjusted construction cost, as defined, is less than or equal to the current valuation threshold, as defined, the cost of compliance with Section 11B-202.4 shall be limited to 20 percent of the adjusted construction cost of alterations, structural repairs or additions. When the cost of full compliance with Section 11B-202.4 would exceed 20 percent, compliance shall be provided to the greatest extent possible without exceeding 20 percent.
When the adjusted construction cost, as defined, exceeds the current valuation threshold, as defined, and the enforcing agency determines the cost of compliance with Section 11B-202.4 is an unreasonable hardship, as defined, full compliance with Section 11B-202.4 shall not be required. Compliance shall be provided by equivalent facilitation or to the greatest extent possible without creating an unreasonable hardship; but in no case shall the cost of compliance be less than 20 percent of the adjusted construction cost of alterations, structural repairs or additions. The details of the finding of unreasonable hardship shall be recorded and entered into the files of the enforcing agency and shall be subject to Chapter 1, Section 188.8.131.52, Special Conditions for Persons with Disabilities Requiring Appeals Action Ratification.
For the purposes of this exception, the adjusted construction cost of alterations, structural repairs or additions shall not include the cost of alterations to path of travel elements required to comply with 11B-202.4.
In choosing which accessible elements to provide, priority should be given to those elements that will provide the greatest access in the following order:
- An accessible entrance;
- An accessible route to the altered area;
- At least one accessible restroom for each sex or one accessible unisex (single-user or family) restroom;
- Accessible telephones;
- Accessible drinking fountains; and
- When possible, additional accessible elements such as parking, signs, storage and alarms.
If an area has been altered without providing an accessible path of travel to that area, and subsequent alterations of that area or a different area on the same path of travel are undertaken within three years of the original alteration, the total cost of alterations to the areas on that path of travel during the preceding three-year period shall be considered in determining whether the cost of making that path of travel accessible is disproportionate.
