Permit takeaway

Helena states that owners or authorized agents must apply for and obtain the required permit before regulated building, electrical, gas, mechanical, or plumbing work is done.

Zoning and placement

Civic Access can also manage planning and zoning cases, so homeowners should verify zoning, site placement, corner visibility, historic demolition, and address issues before construction.

Building and trade review

Helena permit types include residential one- and two-family dwellings, decks, demolition, alternative energy, roofing, retaining walls, mechanical, plumbing, and other common scopes.

Call before applying when
