Buena Park is a vibrant city of approximately 82,000 residents in northwest Orange County, best known as the home of Knott's Berry Farm — one of America's oldest theme parks — and the surrounding Entertainment Corridor along Beach Boulevard. This tourism and hospitality infrastructure generates significant employment and year-round rental demand from seasonal and full-time workers. Beyond the entertainment district, Buena Park is a diverse, family-oriented community with established residential neighborhoods featuring single-family homes from the 1950s–70s on lots typically ranging from 5,000–7,000 sqft. The city sits at the crossroads of the 5 and 91 freeways, providing excellent commute access to Anaheim, Fullerton, Cerritos, and downtown LA. Buena Park's public schools serve through the Buena Park School District and Centralia School District at the elementary level, with Savanna and Western high schools in the Anaheim Union High School District. The city's relatively affordable home prices compared to surrounding communities make ADU investment here particularly attractive for maximizing rental returns.
