Texas law requires licensed assisted living facilities to maintain emergency power systems. This is not a marketing promise. It is a condition of licensure under Texas Health and Safety Code §247.073. But what the law requires, what facilities actually deliver, and what that gap looks like during an emergency are three very different things. North Texas families who lived through the February ice storms or sat through triple-digit summers know exactly why that gap matters. This is a life-or-death concern. In this guide, the DFW Senior Living Guide team explores the rules behind backup power in Dallas-area senior living, the real-world risks, and the specific questions families must ask on every facility tour.
Key Takeaways
- Texas HHSC-licensed ALFs must maintain emergency power covering life-safety loads. Type B facilities, which serve non-ambulatory residents, face stricter generator requirements than Type A facilities.
- A generator on the property is not the same as a tested, load-managed generator. Families should ask for the documented load test log, not just a verbal confirmation.
- Nursing homes face a higher federal standard under CMS emergency preparedness rules (42 CFR §483.73), which are more demanding than Texas state requirements for assisted living.
- Generator fuel type (natural gas vs. diesel) has major implications for reliability during widespread, long-term outages common to North Texas weather.
- Five specific questions can reveal whether a facility's backup power plan is real or just paperwork. Ask them before signing any contract.

What Texas Law Actually Requires for Backup Power
Licensed ALFs in Texas must maintain emergency power systems that keep life-safety loads running. Full stop. Under Texas Health and Safety Code §247.073 and Texas Administrative Code Title 26, assisted living facilities are required to provide emergency lighting, support for safety systems, and the capability to activate climate control during a power outage. The specific obligations vary by facility type. Type A and Type B assisted living carry different requirements under HHSC licensing. Type B facilities, which serve residents who cannot self-evacuate, are subject to stricter generator standards. The evacuation fallback that applies to Type A facilities is not an option. Families can verify a facility's current license classification and inspection history through the Texas HHSC licensing portal.
Nursing homes operate under a separate, higher federal floor. Nursing homes in Dallas must comply with federal CMS emergency preparedness rules under Texas Administrative Code Title 26, §554.303 and 42 CFR §483.73. These rules go beyond state ALF requirements. They mandate documented emergency power plans that are reviewed and tested on a set schedule. Dallas County and Tarrant County facilities are inspected by Texas Health and Human Services surveyors for compliance. Deficiencies cited during those surveys are public record. The takeaway for families is clear: the care type matters as much as the facility name when evaluating backup power protections.
Not All Generators Are Created Equal: Natural Gas vs. Diesel
When a facility says they have a generator, the next question should be, "What kind?" The two most common types in senior living are natural gas and diesel. The difference is critical during a widespread DFW weather event.
Natural Gas Generators
Natural gas generators are connected directly to the utility's gas line. This provides a continuous, theoretically unlimited fuel source. During a typical power outage where gas lines remain intact, these systems are highly reliable. They don't require refueling, which eliminates a major logistical challenge during an ice storm or flood. The generator starts automatically and runs as long as the gas flows. This is their primary advantage.
However, they have a key vulnerability. In a catastrophic event that damages gas infrastructure, like a tornado or a massive pressure drop during a deep freeze, the fuel supply can be cut off. It is a less common failure point, but one that can leave a facility completely without power. Maintenance is also a factor; while they require less day-to-day attention than diesel, their complex fuel systems need regular professional service to ensure they will work when called upon.
Diesel Generators
Diesel generators run on fuel stored in a large on-site tank. This makes them completely independent of the local power and gas grid. As long as there is fuel in the tank, the generator will run. This is a huge advantage in events that disrupt utility lines. Most facilities with diesel generators keep enough fuel on hand for 48 to 72 hours of continuous operation, a common benchmark for surviving the worst of a North Texas storm.
The challenge is refueling. During a prolonged, multi-day outage affecting the entire Dallas–Fort Worth metroplex, getting a diesel delivery can become a serious problem. Roads may be impassable, and fuel suppliers will be prioritizing hospitals and first responders. Diesel fuel also requires stabilization and regular testing to prevent it from degrading, adding another layer to the facility's maintenance protocol.
The Role of the Automatic Transfer Switch
The generator itself is only half the system. The automatic transfer switch (ATS) is the brain. This device detects when utility power is lost and automatically signals the generator to start. Once the generator is running at the correct speed and voltage, the ATS disconnects the facility from the grid and connects it to the generator. The entire process should take less than 30 seconds. When grid power is restored, the ATS reverses the process. A faulty or poorly maintained ATS can render a perfectly good generator useless. It is a critical component that must be tested along with the generator itself.
"A facility's generator is only as reliable as its last load test. In North Texas, where ice storms and 105°F summers are both real possibilities, 'we have a generator' is the beginning of the conversation, not the end of it."

North Texas Weather Makes These Rules More Than Paperwork
When Dallas summer heat climbs past 100°F and the power goes out, elderly residents in a facility without working HVAC face a medical emergency within hours. This is not an inconvenience. It is a crisis. Heat stroke risk rises sharply for seniors. Diminished thermoregulation, multiple medications affecting sweat response, and limited mobility all accelerate the danger. UT Southwestern Medical Center and Baylor Scott & White Health treat heat-related emergencies across the metroplex each summer. The patient profile skews heavily toward adults over 65. A facility that loses cooling capacity during a July outage is the exact scenario that HHSC emergency power requirements exist to prevent. This is why climate control, not just lights, is part of the state requirement.
DFW tornado season and winter ice storms are the other two stress tests that reveal a facility's true preparedness. The February ice storms that knocked out power across Dallas, Tarrant, Collin, and Denton counties for days were not a once-in-a-generation event. They were a preview. HHSC requires licensed ALFs to maintain written emergency operations plans that are reviewed annually. These plans must account for extended outages. A generator on the property does not mean the facility ran a full-load test recently. Families should ask specifically when the last documented load test occurred and whether that record is part of the emergency operations plan on file with HHSC. A facility that cannot answer that question clearly has already answered it.
The Caregiver's View: Surviving an Outage
For families, a power outage at a loved one's facility is a moment of extreme stress. Communication breaks down. Anxiety spikes. Knowing how a facility handles these situations from a human perspective is as important as knowing their generator specs.
During an outage, phone lines can go down and cell service can become spotty. A well-prepared facility has a clear communication plan. This often includes a text message alert system for primary family contacts or regular updates posted to a private social media group. Ask about this plan. How will they let you know your loved one is safe? Who is the point of contact, and do they have a satellite phone for true emergencies? A facility that fumbles this question is likely to leave you in the dark, literally and figuratively.
Caregivers on staff are the front line. During an outage, their jobs become exponentially harder. They may be working by flashlight, manually documenting care, and trying to calm anxious residents. A good facility supports its staff during these events with clear protocols, extra supplies, and relief shifts. Ask how they staff during an emergency. Do they have contracts for backup staff? Do they have sleeping arrangements for caregivers who get stranded by an ice storm? A supported staff provides better care. It is that simple.
What Families Should Ask Before Signing an ALF Contract in Dallas
The gap between 'we have a generator' and 'our generator powers resident rooms, HVAC, and the nurse call system' is where families need to press. Most facilities will tell you they have a generator. They will not volunteer that it only powers the exit signs and a single outlet at the nurse's station. You must ask. The NFPA 110 standard, used by engineers, holds that generators should not exceed 80% of their rated capacity. A facility that has added a new wing or upgraded its HVAC since the generator was installed may be dangerously close to that limit. Ask what systems are on the critical load list and if the total electrical draw has been re-evaluated against the generator's capacity. For more context, our tornado preparedness guide for DFW assisted living covers emergency plans in more detail.
Five questions will tell you more than any marketing brochure. Bring these to every tour of assisted living in Dallas:
- What specific loads does your generator cover? Is it just emergency lighting, or does it include resident room HVAC, outlets, and the nurse call system?
- When was the last documented full-load test, and can we review the log?
- What is the fuel source (natural gas or diesel), and what is the plan for extended operation or refueling during a city-wide event?
- How long can your fuel supply sustain operations? The benchmark for North Texas is 72 hours.
- What is your communication plan for families during an extended outage when phone systems may be down?
