Adjacent to the Los Alamitos/Rossmoor Branch Library, the North Seal Beach Center features a large hall available to the public for rent. At 3,500 square feet, it is big enough to comfortably hold 150 people and 60 round dining tables. With a full kitchen and bathrooms, the hall is often rented out for anniversary celebrations or showers. The hall is also regularly used to host senior lunch programs and classes such as ballroom dancing.
