Followers slammed Jenner and Scott in the comments, branding them "selfish" and "inconsiderate", and the post was also criticised by a leading American disability inclusion group.
"I guess celebrities can park wherever they want," a follower noted.
The post drew the attention of The Ruderman Family Foundation, which said Jenner and Scott were violating a "basic right for people with disabilities".
"Accessible parking is meant for people with disabilities who need it," said the foundation's president Jay Ruderman said in a statement to People.
"As a role model to many, this is an opportunity for Kylie Jenner to use her celebrity status to help society understand why accessible parking is a basic right for people with disabilities to be included in daily life."
Jenner has so far not responded to the criticism.
This is not the first time the Keeping Up With the Kardashian star has angered disability inclusion groups.
In 2015, she was slammed for posing in a wheelchair on the cover of Interview.
At the time, the magazine defended the shoot, saying it was "placing Kylie in a variety of positions of power and control and exploring her image as an object of vast media scrutiny."
"Our intention was to create a powerful set of pictures that get people thinking about image and creative expression, including the set with the wheelchair, but our intention was certainly not to offend anyone."
