• Handling a bedroom or basement opening where egress code applies
• Touching a historic facade or a property under preservation oversight
• Using a different window style that affects framing or exterior appearance, such as turning a double-hung opening into a bay window, picture window, or specialty window
• Adding framing repairs, trim rebuilds, or significant water-damage repair around the opening

• Any historic district or HOA documents
