ANSI A117 Review: The Accessible Design and Use of Public Spaces Standard
If you are drafting plans for a new office, renovating a retail space, or managing a municipal building portfolio, the ANSI A117 standard is the document your code officials will ask for. It is not a gadget or a piece of hardware; it is the consensus-based technical standard for accessible design and use of public spaces. When you search for door clearances, turning radii, or reach ranges, this is the source that defines the numbers. The current edition, often referenced as A117.1, provides the specific dimensions and performance criteria required for accessible routes, spaces, and elements. For professionals who need to ensure a building is legally and practically usable by everyone, having the authoritative text of the ANSI A117 is the baseline for compliant design.

What the Official Page Actually Lists
The ANSI Webstore lists the ANSI A117 standard under the Books/Media category. While the specific page fetch for this SKU did not yield a detailed technical spec sheet in the research data, the standard itself is known for containing the following core technical parameters. You should verify the specific edition year (e.g., 2017, 2023) and the exact page count on the ANSI Webstore before purchasing, as editions are updated to reflect changes in building codes.
- Scope: Accessible design and use of public spaces.
- Key Content: Dimensions for accessible routes, spaces, and elements (doors, ramps, toilets, etc.). See options
- Format: Technical standard document (print and digital).
- Publisher: American National Standards Institute (ANSI).
Note: Because this is a technical standard, there are no "materials" or "warranty" in the traditional product sense. The value is in the currency of the data. Confirm the current adopted edition on the brand site, as local jurisdictions may mandate a specific year. Confirm details on the current product page.
Who It's For
This document is essential for professionals who bear legal and professional responsibility for building accessibility. It is not a casual read; it is a reference tool. You can see current options.
- Architects and Designers: You need the exact millimeter or inch measurements for door widths, corridor widths, and turning circles to pass plan review.
- Civil Engineers and Planners: When designing public infrastructure, sidewalks, or transit stops, the ANSI A117 provides the slope and surface requirements.
- Facility Managers: If you are retrofitting an existing building, this standard tells you what "accessible" actually means in measurable terms.
- Code Officials and Inspectors: Used to verify that a project meets the adopted accessibility code.
You can find the current edition and pricing details by checking the ANSI A117 standard.
Who Should Skip
If you are not involved in the design, construction, or compliance of a built environment, this document will likely be overkill. You can see current options.
- General Homeowners: If you are just widening a doorway in your own house for personal comfort, you do not need the full technical standard. A general guide on home accessibility might be more user-friendly.
- Students in Non-Technical Fields: Unless your course specifically requires code compliance, this is too granular.
- Those Seeking "Best Practices" Only: If you want inspirational design ideas rather than hard legal/technical numbers, look for design case studies instead of the standard itself. See options

How to Choose in Five Minutes
Buying a standard is less about features and more about currency and format. Here is how to make the right choice in five minutes:
- Check the Edition Year: Accessibility standards are updated. Ensure you are buying the edition required by your local jurisdiction or the latest consensus version. The ANSI A117 page will list the current active edition.
- Determine Format: Do you need a physical copy for a job site, or is a digital PDF sufficient for office reference? The Webstore usually offers both. See options
- Verify Scope: Confirm that the standard covers "Public Spaces." If you are working on private residential interiors, check if a different residential standard is more appropriate, though A117 is often used as a benchmark. See options
- Compare Price: Standards can be expensive. Ensure the price reflects the full document, not just an excerpt or a summary. See options
- Check for Updates: Look for any recent amendments or addenda that might be bundled with the purchase. See options

FAQ
Is ANSI A117 the same as the ADA? No. The ADA (Americans with Disabilities Act) is a law. ANSI A117 is the technical standard that the ADA references for specific dimensions and requirements. You follow the law, but you use the ANSI A117 standard to know the exact numbers.
Do I need the 2017 edition or the latest one? It depends on your local code adoption. Many jurisdictions have adopted the 2017 edition or later. Always check your local building department's requirements. You can verify the current status of the standard on the ANSI Webstore.
Is there a free PDF available? While summaries and older versions may float around the internet, the official, current, and legally defensible copy is purchased through ANSI. Relying on unofficial PDFs can lead to compliance errors.
What is the difference between A117 and A117.1? "A117.1" is often used to refer to the first edition of the standard or a specific revision. The naming convention can vary by year. Always look for the full title and year on the product page to ensure you are getting the correct document. You can see current options.
Bottom Line
The ANSI A117 is not a product you "use" in the traditional sense; it is the rulebook for inclusive design. If your work involves creating or modifying public spaces, this document is non-negotiable. It provides the precise, consensus-based metrics that keep buildings safe and accessible. If you are in the architecture, engineering, or facility management field, having the current edition on your desk is a mark of professionalism.
