Carrie Underwood's 400-Acre Home: Preliminary Investigation Reveals Cause Of Fire

Over the weekend, a fire broke out at the 400-acre Tennessee residence of Carrie Underwood, 41, and MikeFisher, 44, while the entire family was inside.

Luckily, the "Before He Cheats" singer and her family, including Fisher, sons Isaiah, 9, Jacob, 5, and their pets, are all safe and unharmed.

Following the house fire, Carrie Underwood's rep released a statement confirming the severity of the incident, and the Williamson County Fire and Rescue revealed what they think caused the blaze.

According to the Williamson County Fire and Rescue, a call came in at 9:42 p.m. on Father's Day to put out the fire, with all eight stations responding. When they arrived at the scene, they found a “fully-involved fire” in Underwood’s garage.

They later provided more details about the terrifying incident, revealing that "The homeowner reported that a UTV was on fire next to the garage," per E! News.

"All occupants in the home were able to escape unharmed," authorities said. "No injuries were sustained by the occupants or firefighters on scene." The flames were quickly extinguished thanks to a "10,000 gallon reservoir on the property."

"Crews from all eight of our stations responded," the fire department said. "Fairview Fire provided a tanker and crew as well. Upon arrival, 1401 found flames coming from the garage. Crews were able to knock down the fire quickly to prevent spread into the house."

A spokesperson for Underwood and her family confirmed to E! News that the fire was "quickly contained" at their property on Sunday.

"There was no fire damage to the primary residence," the rep told the outlet. "And the family and their pets were unharmed."

The investigation is ongoing, but it is believed the fire was sparked by the UTV in the garage.

The mother of two has always been big on balancing family life and work, ensuring she and her husband, Mike Fisher, can navigate the ups and downs to remain focused on what's important.

"I remember when we first found out we were gonna have him [Isaiah], it [was] like, 'How are we gonna do this? Our lives are so crazy as it is,' " she told PEOPLE Magazine. "But you just make room, and you learn how important that family time is, and to be able to spend time and carve out some of that and maybe get to go on vacation and maybe get to go on a cruise — that stuff is so important to, like I said, make time for family. That's what it's all about."

Reflecting on 2020, when the entire world was placed in lockdown due to the COVID-19 pandemic, Carrie Underwood said it was hard because she had "never been in one place" for as long as she was during the lockdown.

"I've never been in one place for this long in the past 15-plus years of my career," Underwood shared with the TODAY show. "So it's been really great to just really get to know them and watch them grow — especially Jake. It's such a critical time in his life and I'm never gonna get it back. So we're just trying to enjoy it."

In addition to their two kids, Carrie and Mike also share three dogs, the most recent being Charlie.

"Meet Charlotte 'Charlie' Nilla Fisher…newest member of the family!" the country music artist shared on Instagram last year. "I met her in Charlotte when the lovely people at @pincdogrescue brought some puppies to the venue to make us all smile. We had been looking for the right pup for our family for a while and she seemed just too good to be true!"

"She is happy at home playing with her boys…and Penny and Zero have responded well and are getting to know their new sister…Thank you, Pawsitive Impact NC Dog Rescue for all the incredible work you do and thanks for bringing this sweet girl into our lives!" she added.
