Inscription.
In 1917, Lewis E. McCann hired Campbell Construction Company to construct this classic Commercial style building which housed his hardware store. It was built with reinforced concrete for $20,000 and sold for $30,000 in 1923. This early 20th Century building embodies character-defining features such as a recessed, double-door entrance, a brick veneer bulkhead, large plate glass windows to showcase store merchandise, and a banding of transom windows allowing natural light to enter the store. The McCann Block Building is one of the finest of its kind in downtown Ontario.

Erected 1998 by City of Ontario, California. (Marker Number 26.)
