Midvale's own history of Main Street describes the street's industrial era role and identifies the Avenues neighborhood as housing built for industrial workers and their families (Engage Midvale).
Today Main Street is an arts and culture district. That is a revitalization designation, not a regulatory historic district.
Permits and inspections
Midvale's Building & Safety division handles permits and inspections. Its published exemptions are specific, so do not assume a repair or a short wall is exempt without checking.
Repairing older brick
On older homes, replacement mortar should be no harder than the brick around it (NPS Preservation Brief 2). A hard patch on soft brick tends to cause the spalling it was meant to prevent. See tuckpointing for more.
