Last reviewed: July 5, 2026

Overview

Chapter 11B sets the accessibility scoping and technical rules for public buildings, public accommodations, commercial buildings and public housing; its stated purpose and application are in §11B-101, which frames the chapter as requirements for design, construction, additions and alterations to make sites, buildings and elements accessible to persons with disabilities . Division 2 of Chapter 11B contains the scoping requirements that determine where those technical rules apply, beginning with §11B-201 (Application) and the provisions for existing buildings and alterations in §11B-202 .

Key practical rules include the equivalent facilitation allowance in §11B-103 (permitting alternate designs that provide substantially equivalent accessibility) and the path-of-travel and limited-scope rules for alterations (for example §11B-202.4 and related exceptions) that control how much work is required when existing facilities are altered . The chapter also includes administrative and maintenance duties (e.g., §11B-107 appeals and §11B-108 maintenance of accessible features) to ensure features remain usable over time .

    11B- 101.1 General. This chapter contains scoping and technical requirements for accessibility to sites, facilities, buildings and elements by individuals with disabilities. The requirements are to be applied during the design, construction, additions to, and alteration of sites, facilities, buildings and elements to the extent required by Chapter 1, Section 1.9.

    11B- 101.2 Reserved.

    11B- 102 Dimensions for adults and children. The technical requirements are based on adult dimensions and anthropometrics. In addition, this chapter includes technical requirements based on children’s dimensions and anthropometrics for drinking fountains, water closets, toilet compartments, lavatories and sinks, dining surfaces and work surfaces. 11B- 103 Equivalent facilitation. Nothing in these requirements prevents the use of designs, products or technologies as alternatives to those prescribed, provided they result in substantially equivalent or greater accessibility and usability.

    SECTION 11B- 104—CONVENTIONS

    11B- 104.1 Dimensions. Dimensions that are not stated as “maximum” or “minimum” are absolute.

    11B- 104.1.1 Construction and manufacturing tolerances. All dimensions are subject to conventional industry tolerances except where the requirement is stated as a range with specific minimum and maximum end points.

    11B- 104.2 Calculation of percentages. Where the required number of elements or facilities to be provided is determined by calculations of ratios or percentages and remainders or fractions result, the next greater whole number of such elements or facilities shall be provided. Where the determination of the required size or dimension of an element or facility involves ratios or percentages, rounding down for values less than one half shall be permitted.

Frequently asked questions

What buildings and spaces are covered by Chapter 11B?

Chapter 11B applies to all areas of newly designed and newly constructed buildings and facilities and to altered portions of existing buildings and facilities; see §11B-201.1 and related application provisions in Division 2 for temporary structures and construction support facilities .

How do additions and alterations trigger accessibility work?

Each addition must comply with new-construction requirements and Section 11B-202.4 prescribes path-of-travel work when alterations are made; altered elements or spaces must meet applicable Division 2 requirements, though limited-scope exceptions may restrict the retrofit required for small or narrowly scoped projects .

Can alternative designs be used to meet accessibility requirements?

Yes—§11B-103 allows equivalent facilitation: alternative designs, products, or technologies may be used if they provide substantially equivalent or greater accessibility and usability .
