Thank you for your interest in joining our webinar, "When Original Isn't an Option: The Case for Substitute Materials," presented by Susan Lawson, AZ SHPO Architect on Thursday, August 6, 2026. The webinar will run from 10:00 - 11:00 a.m. PDT, Arizona time.

The Secretary of the Interior's Standards for Rehabilitation emphasize repairing historic architectural features whenever possible rather than replacing them. Standard 6 states that when replacement is necessary, the new feature should match the original in design, color, texture, and when possible, in materials. While using the same material as the historic feature is always preferred, the Standards recognize that this isn't always practical. That's why they allow some flexibility when selecting replacement materials. When carefully chosen, substitute materials can closely match the appearance and performance of historic materials and can be used successfully in rehabilitation projects while still meeting the Standards.
