Know Before You Buy: Health Code Requirements for Transaction and Drive-Thru Windows

Transaction windows and drive-thru windows have become an essential part of many businesses, from pharmacies and banks to restaurants and government offices. These windows provide a secure, convenient way to serve customers while minimizing direct contact. But just like any other point of customer interaction, they must comply with health and safety codes to ensure both employees and the public are protected.

Below are some of the most common health code requirements related to transaction and drive-thru windows:

1. Window Size and Placement

Health codes often specify the maximum distance between the service counter and the customer. For food service, the window opening typically cannot exceed a certain size—often 216 square inches—unless protective barriers are in place. This prevents outside contaminants such as dust, insects, or vehicle emissions from entering the building.

2. Window Screens or Air Curtains

In many jurisdictions, any opening that connects the outside environment to a food preparation or handling area must be protected. This is commonly achieved through:

• Screens with fine mesh that block insects.

• Air curtains that blow a steady stream of air downward to create a barrier against pests and dust. These measures ensure that the integrity of the indoor environment is maintained even when the window is open for service.

3. Proper Seals and Closures

Windows should close tightly when not in use to prevent contamination. Weather stripping and tight seals are essential, especially in restaurants, where even small gaps can allow pests to enter.

4. Employee Hygiene and Safety

Health codes also extend to how employees interact at transaction windows. Common requirements include:

• Handwashing stations within easy access of employees working the window.

• Gloves or utensils for handling items to prevent direct hand contact.

• Sanitization protocols for frequently touched surfaces, like counters and ledges.

5. Separation from Food Prep Areas

Drive-thru or transaction windows should not open directly into areas where food is actively being prepared. A designated service zone helps maintain sanitary boundaries, reducing the risk of contamination.

6. Ventilation and Air Quality

Because drive-thru windows face constant exposure to outdoor air and car exhaust, ventilation is important. Exhaust fans or proper HVAC systems ensure clean airflow inside, protecting both workers and customers.

7. Accessibility Compliance

While not strictly a health code, windows must also meet ADA (Americans with Disabilities Act) guidelines where applicable. This ensures all customers can access services safely and comfortably.

Why Compliance Matters

Health code requirements for transaction and drive-thru windows are not just red tape—they exist to safeguard the health of both employees and customers. Non-compliance can lead to contamination risks, fines, or even closures.
