Commercial ADA Compliance Basics for Arizona Business Owners

For Arizona business owners, commercial ADA compliance isn’t optional — it’s a baseline legal requirement for most places open to the public. Whether you’re opening a restaurant in Phoenix, fitting out a retail space in Surprise, or renovating an office in Scottsdale, understanding the ADA business requirements up front saves money, avoids complaints, and makes your space usable for every customer. This guide covers the basics of public accommodations, accessible restrooms, ramps and entrances, parking, and signage, so you know what to plan for before construction starts.

Important context: unlike a private home, a commercial space open to the public generally must follow the ADA Standards for Accessible Design, and Arizona businesses also work within adopted building codes and ANSI A117.1. The figures below are commonly referenced values to illustrate the concepts — they are not a substitute for a current code review by a professional.

What “public accommodation” means

The ADA applies broadly to “public accommodations” — businesses that serve the public. That covers restaurants, retail stores, medical and professional offices, hotels, gyms, and most other customer-facing spaces. A few principles shape everything else:

• New construction and major alterations are generally held to the current accessibility standards.
• Existing buildings have obligations too, often framed around removing barriers where it’s “readily achievable,” and bringing altered areas up to standard when you renovate.
• Both landlord and tenant can carry responsibility in a leased space, so lease terms matter. Clarify who is responsible for accessibility work before signing.

Because obligations differ for new builds versus alterations versus existing conditions, the first step is always a professional assessment of your specific space and plans.

Accessible entrances and ramps

The path from the parking lot to your front door has to work for everyone.

• At least one accessible entrance with a level or ramped, step-free path.
• Ramps are commonly referenced at a maximum 1:12 slope (one inch of rise per foot of run), with level landings and handrails where required.
• Door clearance — a commonly referenced 32-inch clear opening — plus maneuvering room on both sides and hardware operable with a closed fist (lever handles, push bars).
• Thresholds kept low and beveled so wheels roll over them.

Accessible parking

If your business provides parking, a portion must be accessible, and the count scales with lot size.

• A minimum number of accessible spaces based on total spaces in the lot, with a share of those being van-accessible.
• Access aisles — the striped space beside the stall — so a wheelchair or lift can deploy next to the vehicle.
• Signage and location. Accessible spaces are signed and placed on the shortest accessible route to the entrance.
• Firm, level surfaces without steep cross-slopes.

Accessible restrooms

Public restrooms are one of the most scrutinized areas of commercial accessibility, and one of the most common sources of complaints.

• Turning space — a commonly referenced 60-inch turning circle — so a wheelchair can maneuver.
• An accessible stall with proper clear floor space, grab bars, and a door that’s usable from a chair.
• Grab bars mounted into solid backing at commonly referenced heights around 33 to 36 inches.
• Fixture heights and clearances — accessible toilet, a sink with knee clearance and insulated pipes, and a mirror, dispensers, and controls within reach ranges.
• Hardware — lever faucets or touchless controls, and a door operable without tight grasping or twisting.

The restroom is where restaurant and retail build-outs most often need careful planning, because retrofitting one later is disruptive and expensive.

Interior circulation and service areas

Inside the space, customers need to reach and use what you offer. That means accessible routes at least a commonly referenced 36 inches wide through the space, a portion of counters and service points at an accessible height, clear floor space at tables (with a share of accessible seating in restaurants), and reachable controls and displays. In retail, aisle width and reach ranges to merchandise matter. The goal is that a customer using a wheelchair can move through, be served, and pay without help.

Signage and wayfinding

Signage is easy to overlook and easy to get wrong.

• Permanent room signs (like restrooms) commonly require tactile characters and Braille, mounted at a referenced height and location beside the door.
• Directional and informational signs have contrast and character requirements for readability.
• Accessible-entrance and parking signage directs people along the accessible route.

Plan compliance into the build, not after

The cheapest time to get accessibility right is during design and construction. Fixing a non-compliant restroom, entrance, or parking layout after the fact means reopening finished work. A few practical moves:

1. Get a professional accessibility review of your plans and, for existing spaces, the current conditions.
2. Clarify lease responsibility for accessibility work before you commit.
3. Design restrooms, entrances, and parking to standard from day one.
4. Coordinate with your jurisdiction on permits and inspections — requirements are enforced through the building department.

How Desert Wolf Developers helps

We hold a KB-2 dual license, which covers both residential and small commercial construction, so accessible commercial build-outs are within our wheelhouse. As a licensed Arizona general contractor (ROC #364568), we build restaurants, retail storefronts, and office spaces with accessibility designed in — entrances and ramps, accessible restrooms, parking coordination, circulation, and signage — across Phoenix, Surprise, Glendale, Peoria, Goodyear, Scottsdale, Tempe, and the West Valley. We coordinate with your design team and the local building department so compliance is built in, not bolted on. Note that KB-2 commercial scope has limits, so verify current AZROC limits for your project. See our full construction services for the range of work we handle.

To scope a compliant build-out, submit your project with your address and plans, or contact us to talk it through.

This article is general information, not legal or code advice. ADA requirements and ANSI A117.1 standards differ between residential and public-accommodation settings, are enforced differently for new construction, alterations, and existing buildings, change over time, and are not guarantees — confirm current ADA/ANSI and local code requirements with a qualified professional and your jurisdiction before building.
