The upper floor of the Edmonds Historical Museum contains a children's activity area, a research library, and two galleries with rotating exhibits.

The ground floor consists of a series of permanent displays depicting Edmonds' past, including reconstructions of historical locations and objects.

These include a diorama depicting the 1910 Edmonds town site and waterfront, the Cook Victorian Parlor, a room representing an early hotel, a model of a shingle mill, and the preserved jail cell.

It depicts fisherman and animals in the Coast Salish style and features crescents, trigons (or wedges) and ovals.

It also partners with the Edmonds Historic Preservation Commission to document local houses and with other non-profits on various joint programs and exhibits.
