Human vs Veterinary Operating Room Construction: Design, Compliance & Workflow Differences
SE Builders brings deep construction knowledge to the complex requirements of surgical room builds - whether for veterinary practices or human healthcare settings. From airflow and sterilization zones to equipment loads and layout efficiency, we understand what it takes to meet clinical standards while supporting smooth day to day operations. Our team works closely with you to deliver a surgical space that aligns with regulatory needs, protects patient safety, and elevates the overall function of your facility.
What Is an Operating Room - Human vs Veterinary?
An operating room (OR) is a sterile, highly controlled environment designed for surgical procedures that require precise infection control, specialized equipment, and smooth clinical workflow. While both human and veterinary ORs serve the same core purpose - performing surgery safely - they differ in regulatory standards, spatial needs, and patient handling requirements.
Human surgical rooms must comply with guidelines such as the FGI (Facility Guidelines Institute) for design and construction, NFPA 99 for medical gas systems, and ASHRAE 170 for ventilation and air change rates. These standards are enforced by agencies like HCAI (formerly OSHPD) in California to protect patient health and facility compliance.
Veterinary surgical suites, on the other hand, are guided by standards from the AAHA (American Animal Hospital Association) and AVMA (American Veterinary Medical Association). They often require similar HVAC performance, surgical lighting, and seamless finishes, but allow for more flexibility in room size and layout depending on the species treated and the complexity of procedures.
At SE Builders, we understand that whether you're operating on a person or a pet, the construction of the surgical space plays a vital role in safety, efficiency, and long term success.
Why Operating Room Construction Isn’t One-Size-Fits-All
Building a surgical suite isn’t just about installing walls and finishes - it’s about designing for safety, functionality, and compliance. Human and veterinary operating rooms may share some elements, but the requirements for airflow, equipment, patient handling, and regulatory approval vary widely. Without a clear understanding of these differences, even well-intentioned construction can lead to costly redesigns, inspection failures, or operational inefficiencies.
Human vs Animal OR Requirements: Key Differences
While both types of surgical spaces aim to ensure safety and sterility, human and veterinary operating rooms are built under different conditions, with specific needs based on patient type, regulatory oversight, and clinical procedures. Here's how they compare:
Category | Human Operating Room | Veterinary Operating Room |
|---|---|---|
Imaging & Equipment Load | Heavier equipment: C-arms, booms, imaging beds | Typically lighter loads, though dental and ortho gear add weight |
Recovery & Post-Op | PACU areas required, monitored recovery zones | Often includes cage recovery or separate recovery rooms |
Flooring & Wall Finish | Seamless, chemical-resistant with coved upturn | Same requirements—epoxy or welded sheet vinyl preferred |
Surgical Lighting | Ceiling-mounted LED surgical lights | Often uses ceiling or mobile lights, depending on ceiling height |
Patient Transport | Requires wide corridors, gurney access, and ADA compliance | May involve walk-in transfer, mobile lift, or small tables |
Sterility Zones | Strict zoning (clean, semi-restricted, restricted) | More flexibility, but separation of prep/surgery/recovery recommended |
Medical Gas & Scavenging | Medical gas lines (O2, N2O, suction, WAGD) required by code | Often uses portable or hybrid systems; scavenging still critical |
Regulatory Oversight | Governed by FGI, NFPA 99, ASHRAE; reviewed by HCAI (CA) | Follows AAHA/AVMA best practices; varies by state |
Room Size | Typically 400-600 sq ft, depending on procedure type | Often 250-350 sq ft for small animals; larger for equine/exotic |
What Human and Animal ORs Have in Common
Despite serving different patient types and operating under different regulations, human and veterinary surgical suites share several fundamental design principles. Whether you're building for a hospital or an animal clinic, these core elements are critical to safety, efficiency, and compliance.
Key shared design features across both environments:
-
Seamless, Chemical Resistant Flooring
Smooth, coved surfaces reduce bacteria buildup and support easy disinfection essential for infection control in both human and animal surgeries. -
Positive Pressure HVAC Systems
Both types of ORs require carefully balanced air systems that prevent contaminated air from entering the surgical field. Proper air changes per hour (ACH) and directional airflow are essential. -
Zoned Workflow for Sterility
Surgical suites must maintain clear separation between clean, semi-restricted, and restricted areas to reduce cross-contamination and maintain sterile protocols. -
Surgical Grade Lighting
High-CRI, shadow-free lighting ensures visibility during procedures. While human ORs often use fixed ceiling-mounted lights, veterinary ORs may use mobile or ceiling-mounted units depending on case complexity. -
Non-Porous Wall and Ceiling Finishes
Durable, cleanable materials like epoxy-coated surfaces or vinyl wall protection are used in both types of rooms to maintain hygiene and support long-term durability. -
Integrated Equipment Access
Both environments require accessible connections for gases, suction, power, and data whether through ceiling booms, wall panels, or mobile carts. -
Pre and Post Op Flow Considerations
Efficient movement of staff, patients, and equipment before and after surgery is vital to minimize delays and reduce infection risks in any surgical environment.


Why This Comparison Matters
Surgical environments demand more than just clean finishes - they require precise planning, code compliance, and an understanding of how medical teams work in real time. For veterinary practice owners and healthcare professionals alike, overlooking the differences between human and animal surgical room design can lead to costly delays, code violations, or inefficient layouts.
Human ORs are held to strict clinical standards with extensive infrastructure requirements. Veterinary ORs allow more flexibility but still need proper airflow, patient flow, and infection control. Knowing how to design and build for both means avoiding critical mistakes - and creating a safer, smarter surgical environment from the start.



What makes the construction of each surgical space unique:
-
Regulatory Complexity
Human healthcare ORs must meet standards set by FGI, NFPA 99, and ASHRAE 170 - enforced by agencies like HCAI in California. Veterinary ORs follow guidelines from AAHA and AVMA, which are best practice based and less centralized. -
Mechanical & HVAC Requirements
Human ORs demand precise airflow control with HEPA filtration, pressure monitoring, and redundancy. Veterinary ORs often follow similar principles, but system sizing, zone separation, and verification protocols can differ. -
Surgical Workflow & Room Layout
In human ORs, design must support gurney access, ADA compliance, and multidisciplinary surgical teams. Veterinary ORs often support more flexible patient positioning and equipment movement but still need clearly defined sterile zones. -
Medical Gas Systems
Centralized oxygen, vacuum, and waste anesthetic gas disposal (WAGD) are non-negotiable in human settings. Veterinary facilities may use a mix of centralized or portable systems, depending on practice size and case volume. -
Finishes & Infection Control
Both require seamless, chemical-resistant flooring, coved wall transitions, and non-porous surfaces but the level of documentation and inspection varies by jurisdiction. -
Budget, Timeline & Inspection Process
Human OR projects often undergo longer plan review, phased inspections, and certification before use. Veterinary ORs may move faster but still benefit from professional guidance to avoid costly corrections.
