Findings and geographic context

The Commission rules distinguish replacement of original windows on contributing structures, which requires Commission approval, from replacement of non-original/non-contributing windows, which requires staff approval. Minor repairs without size/style changes are treated as routine maintenance in the stated category.

Evidence family: ["Historic Preservation Commission window replacement review categories"]

Families represented: Historic-property window review or design

Relevant authority: Durham Historic Preservation Commission (Municipal historic-preservation review authority)

Geographic scope: Properties subject to Durham Historic Preservation Commission review; exact designated-property applicability must be confirmed for the address.

Applicability and limitations

Applies to: Historic properties/structures in the Commission's purview; approval category depends on original/contributing status of the windows and structure.

Local Project Considerations

Durham: Regional Factors to Know Before You Build

  • 📋ENERGY STAR window certification is based on climate zone performance (zones 1–5) — ensure the windows you're buying are certified for Durham's zone, not just generically "ENERGY STAR certified." Windows certified in zone 2 (southern hot climates) have different U-factor and SHGC specifications than zone 5 (northern cold climates). The wrong certification zone means underperformance in your specific conditions.
  • 💰The IRA 25C credit applies up to $600/year ($200/window max) for qualifying ENERGY STAR certified windows. This is a direct tax credit. North Carolina utility rebates may stack on top. The combined incentives typically cover 15–25% of project cost for a qualifying window replacement project.
  • 🔧Window installation quality is as important as glass performance. Air infiltration at poorly installed windows — inadequate insulation, missing flashing tape, improper sealant — can equal the heat loss of the glass itself. Get a written air infiltration warranty from your installer and confirm the rough opening preparation approach before work begins.
