Required

The City's Building Permits page says "All permit applications are managed by the City of Webster Groves Planning & Development Department" and can be submitted online, by email, or in person at City Hall, and that "Your permit will be subject to plan review for code compliance." It states that an application is required for "Construction or alteration to the exterior or interior of a structure." The page does not say whether a roof replacement requires a permit, so the department should be asked.

The City's Permits page says "The City of Webster Groves has adopted the following codes" and lists the "2015 International Residential Code (IRC)" with the 2015 International Building, Existing Building, Fire, Mechanical, Plumbing and Property Maintenance Codes and the 2014 National Electric Code. A City news item for an October 22, 2026 open house says "The City is updating its technical building codes to align with the 2021 ICC International Codes," that the proposed codes "have been publicly displayed since July 21, 2026," and that the update "also removes or revises a number of legacy local amendments." The City's codified adopting section and its local amendments to the International Residential Code were not read for this record, so it gives no answer that depends on them.
