The concerns came after rocks and boulders rolled and flew into the neighborhood properties causing damage.
Some neighbors say the construction has been an inconvenience to say the least, they say their property has been damaged and they think somebody could get hurt.
Developers were blasting part of Camelback Mountain to make way for a new home near Valle Vista and Arcadia, but neighbors hope it's not at the expense of their houses.
Homeowners say videos posted online show boulders tumbling down Camelback onto their properties.
Two homeowners who live below the construction site say their driveways were damaged from the construction. One driveway was repaired within days, although the homeowners say it wasn't done adequately, and their shade sail was ripped.
The same homeowner showed us photos of a boulder and a piece of equipment that they say landed in their driveway.
The most recently blast, according to them sent boulders sliding within feet of their home, taking out Palo Verde trees along the way.
The homeowners don't want to comment on camera, saying they want to make sure the company will fix the damage. The company, Bedrock Developers say it will.
"We'll make sure the driveway is repaired and replace, to make sure they understand we recognize the responsibility there, and we'll make sure they're happy," said Lance Yates.
Candelaria Design Company posted a rendering of the home being built on their Facebook page. The developers said the blasting was designed to speed up the process so neighbors wouldn't have to endure months of jack hammering.
But the city went to the site Friday and issued a notice to stop work until the boulders, leaning up against a catch fence have been removed, and until the company can prove they can adequately protect the surrounding property.
The project manager said safety is their priority.
"It's a daily concern, something our contractors and I did talk about on a daily basis, everything we do is focused on keeping our job site safe and the adjacent property safe as well," said Yates.
The developer said the explosions, although smaller are expected to last another month.
The project manager said everything has been done within city guidelines and says they've surpassed city requirements for rock fall barriers.
