The house was redesigned and enlarged under the supervision of an undergraduate member David Adler of the 1904 Section, with the assistance of Professor Harris of the faculty.

After the United States entered World War I, Charter was temporarily closed due to reduced membership caused by widespread member enlistment in the armed forces.

Reopening in 1919, Charter quickly gained a reputation as a club personifying the era of the Roaring '20s, carving a niche for itself on campus in the inter-war years.

Charter greatly expanded its membership after the war, but disaster struck closer to home in 1949 when a fire spread rapidly through much of the first and second floors causing heavy damage.

It was some of these gridiron heroes who allegedly planned the raucous celebration of the admission of the new sophomore section which led to 45 members sent to McCosh Infirmary or Princeton Medical Center for alcohol-related reasons.

The Princeton Borough Police quickly rounded up the Charter officer corps, and criminal charges were brought against the president and social chair, who were convicted of serving alcohol to minors, fined $500, and sentenced to 30 days in jail.

The sentences were later overturned by a Mercer County Court judge, and the two undergraduate officers received probation and were ordered to perform community service.
