Plan check correction: accessible path of travel in alterations
Tenant improvements often get this comment even when the work never touches the entrance. Accessibility rules reach beyond the altered space to the route that serves it.
The comment asks you to show the accessible route from the site arrival points to the altered area, including the entrance and the restrooms, drinking fountains, and public phones that serve it, and to say which elements are being upgraded. Clear it with a path-of-travel plan, a survey of existing conditions, and, where improvements are limited by cost, the valuation and the upgrades chosen.

Comment
Show the accessible path of travel to the area of alteration, including parking, entrance, and restrooms serving the area. Provide a disproportionality statement if applicable.
Response
Revised as requested. Path-of-travel plan A1.02 traces the route from accessible parking to Suite 210, with existing conditions noted at each element. The primary entrance hardware and restroom grab bars are upgraded; details on A7.03. The construction valuation and the upgrades selected, in the order the code requires, are listed on G0.02.

Questions, answered
Path of travel in alterations: questions
What is the 20 percent rule?
Under the federal ADA rule in 28 CFR 36.403, when an alteration affects a primary function area, the path of travel must be made accessible unless the cost exceeds 20 percent of the cost of the alteration to the primary function area. Upgrades up to that amount are still required, in priority order.
Does California use the same rule?
California’s CBC Section 11B-202.4 has its own path-of-travel requirements, including a valuation threshold that is adjusted over time and a 20 percent provision. Check the current threshold with the department.
Is the path of travel required for every alteration?
Not always. Some work, such as certain repairs and alterations that do not affect a primary function area, is excluded. The plans should state why the rule applies or does not.
