Mirage Post Acute: Illegal Air Conditioner Install - CA
State inspectors found the portable AC unit operating in a resident room on September 4, its ducts snaking through a window and secured with duct tape. The facility had installed the equipment without required state approval and failed to notify licensing officials within five days as mandated by law.
The administrator told inspectors he started using the unit on April 22 after receiving a heat advisory. He had no permit from the Department of Healthcare Access and Information, the state agency that must approve all construction and equipment modifications in healthcare facilities.
"The Administrator stated he did not know what HCAI was and who was HCAI," inspectors wrote.
When confronted about the violation during the inspection, the administrator called the state agency for the first time. He spoke with an HCAI staff member who allegedly told him temporary HVAC use didn't require permits.
But the administrator admitted he had no documented evidence of that conversation.
The maintenance supervisor offered conflicting explanations for the unauthorized installation. He initially said the portable unit was installed "temporarily due to the hot weather" and claimed there were nine HVAC units throughout the building.
The maintenance assistant contradicted his supervisor, stating only one portable AC was installed in the entire facility. The assistant said the unit was added "due to resident request" and insisted the facility's existing air conditioning system was working properly.
"The MA stated that the AC of the facility was working and has no problem," inspectors noted.
The supervisor acknowledged the existing HVAC system was "just blowing low air" and needed duct work checked, undermining claims that the portable unit was only for extreme weather.
Inspectors observed the makeshift installation during their morning rounds. The portable unit's ducts were attached to wall-mounted window paneling and held in place with duct tape, a modification that altered the building's ventilation system without engineering review.
The facility's own policies, revised just two days after the unauthorized installation began, stated portable HVAC systems should only be used during power outages or extreme weather conditions. The maintenance policy required staff to "follow established safety regulations to ensure the safety and well-being of all concerned."
The Department of Healthcare Access and Information, formerly known as the Office of Statewide Health Planning and Development, reviews all construction plans, repairs, renovations and remodeling in healthcare facilities to ensure compliance with state building codes. The agency's approval process exists to prevent safety hazards that could endanger residents.
Federal inspectors classified the violation as having potential for actual harm to residents, noting that unauthorized building modifications could create safety risks. The facility's failure to obtain proper permits meant no state engineer had reviewed the installation's impact on the building's structural integrity, electrical systems, or fire safety measures.
The administrator's unfamiliarity with basic regulatory requirements raised additional concerns about the facility's compliance culture. His admission that he didn't know the state oversight agency or how to contact them suggested broader gaps in administrative knowledge of healthcare facility regulations.
The timing of the policy revisions also drew scrutiny. The facility updated both its portable HVAC policy and maintenance procedures on April 24, just two days after installing the unauthorized unit. The hasty policy changes appeared designed to retroactively justify the installation rather than guide proper procedures.
State building codes for healthcare facilities include specific requirements for HVAC modifications because improper installations can create fire hazards, electrical risks, or ventilation problems that endanger vulnerable residents. The duct tape securing system observed by inspectors would not meet professional installation standards required in licensed healthcare facilities.
The maintenance staff's contradictory statements about the facility's cooling capacity further complicated the violation. While claiming the existing system worked properly, they simultaneously acknowledged it was "blowing low air" and needed repairs, suggesting the portable unit addressed ongoing mechanical problems rather than temporary weather conditions.
The facility operated the unauthorized equipment for more than four months before state inspectors discovered it during a complaint investigation. During that period, no state engineer had evaluated whether the installation met safety codes or posed risks to the 150-bed skilled nursing facility.
Residents at Mirage Post Acute remained exposed to potential safety hazards from the unauthorized building modification while administrators scrambled to justify an installation they should have never begun without proper permits and state approval.
