The market space became a center of the Ohio City community for the next three decades and other benefactors donated adjacent lands allowing the marketplace to expand.

Cleveland architectural firm Hubbell and Benes was contracted to create the new indoor space and, after nearly a decade of planning and construction, the current West Side Market building was completed in 1912 at a cost of nearly $680,000.

The market also began sponsoring major food festivals in the neighborhood which drew people from Cleveland and the rest of the world.

A 2004 project enclosed and added space heating to the arcade portion of the market, as well as completed major interior and architectural renovations to the main building.

The current roster of tenants includes those of Irish, German, Slovene, Italian, Hungarian, Greek, Polish, Russian, and Middle Eastern descent, among others.

"[4] In 2016 city officials announced that starting April 3 of that year the market would add regular Sunday hours for the first time in its history.
