Medical Office Building Construction in the Boulder Valley

Louisville has two hospitals, AdventHealth Avista and Centennial Peaks Hospital, and the approved Redtail Ridge plans call for relocating Avista Adventist Hospital as part of a larger campus along U.S. 36. Medical office buildings gather around that kind of change. Physician groups, imaging centers, urgent care and specialty clinics like to be within a short drive of an inpatient campus, and they plan their leases around where the hospital will be, not only where it stands.

A medical office building looks like an office from the street and works like a small piece of a hospital inside. Exam rooms need sinks and cleanable finishes, imaging rooms need shielding and structure, and the electrical and data load per square foot is well above that of a standard office. We build these buildings for developers who lease to clinicians, and for practices that own their space, and the questions we raise at the start are the same for both: what the first tenant needs, what the third tenant will need, and what the plan reviewer will ask about.

What goes into the walls before the cabinets arrive

Plumbing is the first difference from an office. A typical exam room has a sink, and a suite of twenty has twenty tied into waste and vent risers that were sized at the beginning of design. Stacked suites need careful chase layout so that a third-floor dental or surgery tenant can be served without opening the second floor. We coordinate those risers with the structural engineer before the slab is poured, because penetrations through post-tensioned or deep structure are not something to improvise.

Then come the rooms that carry specialized requirements: lead-lined walls for radiography, vibration and floor-loading allowances for imaging, medical gas for ambulatory surgery, and sterile processing with its own air balance. We organize the building so that these suites sit on a ground floor or over a specific column grid, and we leave shells for lighter uses on upper floors. That arrangement keeps the base building affordable and lets tenants with heavy needs share the cost of structure fairly.

Which code edition governs, and what the energy rule exempts

Louisville adopted the 2024 International Building Code, Residential Code and Fire Code effective December 6, 2025. In Lafayette, which has a hospital campus with more than 200 beds according to a 2012 regional business report, the 2021 building code was in force in the tracker we reviewed, with the 2024 edition and the 2026 National Electrical Code planned for the third quarter of 2026. Confirm any date with the building department before you rely on it.

In the City of Boulder the energy code requires commercial buildings to be all-electric, and the exceptions it lists name hospitals, labs and commercial cooking. Outpatient clinics are not on that list, so we plan a medical office for the all-electric path, which needs to be 10 percent better than ASHRAE 90.1-2022, unless the building department tells us otherwise for a specific use. Heat recovery and a tight envelope do most of the work, and sterilizers and autoclaves are checked for how they are served. If your project sits in unincorporated Boulder County, see our notes on county rules for its different amendments.

Building around patients who are already in the building

The medical offices that cause the most trouble are not new buildings, they are suites built into occupied ones. When a pediatric group sits one floor below a new imaging suite, noise, dust and vibration become patient-safety issues, not just inconveniences. We prepare an infection control and dust plan for any work next to occupied clinical space, and we hold a briefing with the practice manager before demolition starts. Negative air machines, sealed barriers and after-hours noisy work are how we set up phased work in occupied buildings.

Life safety also changes with use. An ambulatory surgery center may be classified differently from a physician office, and sprinklers, fire alarms, exit widths and smoke compartments follow the occupancy. We ask the fire marshal for a preliminary reading in schematic design and keep a written record of the answer, so the tenant's architect works from the same premise as ours.

Matching delivery to lease commencement

Medical tenants hold hard dates. A practice that closes one location has patients scheduled at the next one, and a delayed certificate of occupancy has a daily cost for them. We schedule backward from that date: state licensing or accreditation visits where relevant, equipment delivery and installation, then final inspections, then finishes. Long-lead items such as imaging equipment, specialty exhaust and electrical gear are tracked on a separate list.

For developers, the delivery question is different, because the shell has to stand and be accepted while tenants are still negotiating. We usually recommend a warm shell with the mechanical stub-outs, plumbing risers and electrical service sized for the likely tenants. It costs more at the start and saves months when a clinic signs. Compare this with the office building approach, where a plainer shell is often enough.

The people in the room during preconstruction

We start preconstruction by meeting the clinicians, not only the developer. A dentist, a dermatologist and a physical therapy group all have different requirements, and the room counts and layouts they describe often reveal expenses the architect has not seen. The goal is a base building that suits the tenants and a cost plan that matches it.

Where a project connects to a hospital campus, we also talk with the owner of that campus about utility connections, access and construction traffic. The same planning applies to hospital construction, only with more parties at the table. For health systems and physician groups, the healthcare systems industry page outlines how we work with them.

Questions Owners Ask

How close should a medical office building be to a hospital?

There is no rule, but physician groups often prefer a short drive from the inpatient campus they refer to. In Louisville, the Redtail Ridge plans include moving Avista Adventist Hospital, so developers there are watching where that campus ends up. We recommend leasing assumptions be checked against announced plans, not rumors.

What is the biggest cost difference from a regular office?

Plumbing, electrical density and specialized rooms. Every exam room with a sink adds waste and vent runs, and imaging adds shielding and structure. We separate base building costs from tenant improvements so the developer can see which costs belong to the shell.

Can the building be all-electric in Boulder?

Yes. The city's all-electric requirement applies to commercial buildings, and its exceptions list hospitals, labs and commercial cooking but not outpatient clinics. Sterilization and a few other loads need attention, but a well-designed outpatient building can meet the 10 percent better than ASHRAE 90.1-2022 target without gas.

Do you build tenant suites inside occupied medical buildings?

Yes, and we plan the work around the patients. That means infection control barriers, negative air, scheduled shutdowns for utilities, and noisy work after hours. We meet with the practice manager before demolition to confirm the rules.

Which codes will a medical office in Lafayette or Longmont follow?

In the tracker we reviewed, both were on the 2021 International Building Code with the 2024 edition planned. Longmont's own page later listed the 2024 codes as adopted. Because the dates have moved, we confirm the edition with the department before design.
