Enough funds had finally been raised to purchase land for a permanent library building. Property for the future McAllen Memorial Library was purchased at 600 N. Main St. from Pete Bonneau for $10,000. Construction began later that year while fundraising efforts continued throughout the community.
The building was designed by architect Zeb Rike, with construction completed by Marchant Brothers of Mercedes at a cost of $23,751. Because the full amount could not be raised through donations alone, the remaining balance was financed through city taxes.
