Henderson firefighters rushed to a two-alarm commercial fire before sunrise Thursday at a three-story office complex on St. Rose Parkway, a building that houses both a major Nevada construction firm and a women's health clinic. Crews were dispatched around 6:24 a.m. to 2580 St. Rose Parkway, a stretch of roadway between the 215 Beltway and Eastern Avenue, after reports of visible fire conditions at the site.
The response, first reported by KSNV, escalated to two alarms, triggering additional engine and truck companies beyond the standard callout. As of the station's report, the extent of damage had not been determined and injuries had not been confirmed. News 3 said it had reached out to the City of Henderson for further updates on the incident.
The address places the fire at Saint Rose Corporate Center - Building One, a Class A commercial office building spanning roughly 60,000 square feet that was constructed in 2018, according to a LoopNet property listing. The three-story structure is built with 20,000-square-foot floorplates designed for multi-tenant professional office suites, a layout that can complicate access and containment during a fast-moving fire.
Corporate and Medical Tenants Inside the Building
Among the tenants inside the complex is the regional headquarters of McCarthy Building Companies, one of Nevada's largest general contracting firms, which occupies Suite 200, per the company's own location listing. The building also houses medical providers, including Women's Health Associates of Southern Nevada, which runs an outpatient mammography center in Suite 140, according to the practice's facility page. That mix of corporate offices and patient-care space raises the stakes of any fire response inside the building, given the potential presence of medical equipment and sensitive operations on-site.
Henderson Fire Department protocol calls for four-person crews — a captain, engineer, firefighter paramedic, and firefighter — staffing frontline engine and 100-foot ladder truck companies, per the department's own description of its emergency services staffing model. A two-alarm call automatically pulls in additional engine and truck companies beyond that standard response. The department is an ISO Class 1 rated agency, the highest public protection rating available, running 12 fire stations across more than 105 square miles to protect over 335,000 residents, according to Henderson Professional Fire Fighters IAFF Local 1883.
Alarm Verification Rules and Recent Fire History
Henderson Fire also maintains a verified alarm policy that generally requires secondary confirmation, such as visible smoke or a water-flow system activation, before a full structural response is dispatched to an automatic commercial alarm, according to reporting from Fire Engineering. That policy, established to cut down on false-alarm callouts across the Las Vegas valley, underscores that Thursday's two-alarm response followed confirmation of an actual fire condition rather than a routine automatic trip.
Thursday's blaze is not the department's first major structural fire this summer. Less than a month earlier, on July 29, Henderson firefighters responded to a structural fire near Green Valley Parkway that hospitalized one person for smoke inhalation and displaced two residents, per the Daily Dispatch. Earlier in the year, on June 24, a major Henderson fire forced the evacuation of multiple neighboring commercial businesses along Lake Mead Parkway while crews contained the blaze, as reported by FOX5 Las Vegas.
A Booming Commercial Corridor
The St. Rose Parkway corridor has seen rapid commercial growth in recent years, anchored by mixed-use developments like The Village at St. Rose and Saint Rose Corporate Center, which together draw thousands of daily workers and visitors, Hoodline has previously reported. That density helps explain why a fire in one office building along the corridor can prompt a rapid, multi-unit response.
Key questions remain unresolved. The cause and origin of Thursday's fire have not been determined, and it is not yet known whether the building's sprinkler or water-flow systems activated as designed. The full physical and financial toll on tenants inside the three-story structure, including McCarthy Building Companies and Women's Health Associates of Southern Nevada, has also not been assessed. Hoodline will update this story as additional details become available.
