After being officially incorporated as a city in 1952, Campbell began losing its orchards to rapidly growing residential areas made up of mostly single-family homes. In the decades that followed, new designs and styles were introduced, with the City of Campbell naming the Queen Anne Cottage, Colonial Revival Cottage, Craftsman, Prairie, California Bungalow, Spanish Eclectic, and Tudor Revival as the most common architectural styles in the community.

In fact, an architectural landmark in Campbell — known as the Ainsley House — is a Tudor-style home built in 1925 by an affluent family of the same name. Now it is a small, quant town with an abundance of events and festivals in the downtown area, celebrating the community and the people in it. The mild and mostly warm weather allows for outdoor celebrations and activities throughout the year.
