A fire tore through a three-story apartment building in Miami on Wednesday afternoon, displacing several families from an 18-unit complex on the 2100 block of West Flagler Street after flames spread through crawl spaces, wall voids and the attic. City of Miami firefighters responded around 3:25 p.m., and officials said the blaze was brought under control in about an hour.
Firefighters arriving on scene encountered smoke pouring from the building's crawl spaces, according to fire officials cited by NBC 6 South Florida. To track down flames hidden inside the structure, crews used thermal imaging cameras and a drone to locate hotspots that weren't visible from the ground. That approach mirrors how the City of Miami Department of Fire-Rescue has increasingly leaned on tethered Fotokite drones with live aerial video feeds to size up fires in real time, a tactic the department has highlighted as recently as this year.
Of the building's 18 apartments, 16 were occupied at the time of the fire, and more than 20 residents were accounted for once the flames were extinguished. Several pets were also accounted for, according to the same report. No injuries were mentioned in connection with the fire.
Drones Chase Flames Through Hidden Voids
Fires that burrow into crawl spaces, wall cavities and attics are notoriously difficult to fight because flames can travel unseen between units long after the visible fire looks contained. Industry experts writing in FireRescue1 have noted that Drone as First Responder systems equipped with thermal imaging let commanders map heat signatures through dense smoke well before a traditional ground-level size-up would reveal the same information.
Miami Fire Rescue has used the same tools before. Just this past January, firefighters deployed thermal imaging drones during a two-story residential fire to track hotspots and check whether the floors were still structurally sound, a precaution that becomes critical whenever fire spreads through concealed void spaces in older apartment buildings.
Building Could Be Declared Unsafe
The city's building department is expected to deem the structure unsafe, and the cause of the fire remains under investigation. Under City of Miami rules, once a property owner is formally issued an Unsafe Structure notice, they have just 10 days from the date of the violation to file a formal appeal.
If the West Flagler Street building is ultimately tagged unsafe, its owner would face the same compliance clock that governs multi-family properties across the city. Municipal regulations allow owners to apply for up to two three-month extensions on unsafe structure or recertification notices, but each extension carries a $500 fee, according to city documents. Countywide, Chapter 8 of the Miami-Dade County Code separately mandates structural and electrical safety recertifications for commercial and multi-family buildings, enforcement that typically intensifies after fire damage forces a closer look at a property's condition.
Red Cross Steps In as Families Search for Shelter
The American Red Cross assisted displaced residents with temporary housing and other resources in the fire's immediate aftermath. The organization's involvement in Wednesday's response reflects the scale of its work nationally — the Red Cross says it provided disaster relief and recovery services to more than 920,000 people during fiscal year 2025 alone, responding to both major disasters and smaller local crises like residential fires.
Wednesday's fire is the latest in a string of multi-family residential blazes to hit the Little Havana corridor in recent years. In November 2023, a kitchen fire at a two-story apartment building near West Flagler Street and 21st Avenue displaced 10 residents, including five children, after smoke spread through the shared complex, according to Local 10 News. That same month, a separate fire on NW 21st Avenue forced more than 40 residents to evacuate as heavy smoke traveled through shared ventilation spaces, per CBS News Miami. The neighborhood's dense concentration of older multi-unit buildings has repeatedly made widespread displacement a risk whenever fire breaks out in one of them.
No cause has been determined for Wednesday's fire, and it remains unclear how long displaced residents will need temporary shelter or whether the structural damage will ultimately require repairs or a teardown. Hoodline has previously covered a demolition after a Miami fire that followed a similar unsafe structure declaration, underscoring how much hinges on the building department's coming assessment of the West Flagler Street property.
