TMZ reports that the 20-year-old supermodel called the police when she arrived at her Hollywood Hills home and the man followed her as she drove through the gates.
The man was arrested for stalking and there was also reportedly already a warrant out for his arrest.
Kendall bought the home just two months ago from John Krasinski and Emily Blunt.
She splashed out $6.5 million on the stunning property, which features six bedrooms, five bathrooms and a private swimming pool.
Kendall paid $450,000 below the original asking price for the 4,800-square-foot contemporary-style home.
It is situated on Hollywood's Sunset Strip, nestled in the hills above the iconic Chateau Marmont Hotel, and the luxurious living space comes complete with hard wood floors, exposed brick walls, and a rooftop patio.
Thanks to the wide and spacious windows, almost every room in the house has uninterrupted views of the West Hollywood neighborhood and surrounding nature.
The master bedroom also boasts a walk-in closet which will be able to accommodate the fashionista's huge array of designer clothes.
Despite her young age, this is Kendall's second property purchase, after she bought a two-bedroom condo in 2014 for $1.39 million.
