Commission approves window and door replacements at 562 Bellevue after code‑triggered review

The commission approved a scope of work at 562 Bellevue Avenue that includes replacing numerous non‑original or deteriorated windows and doors and installing in‑kind, custom wood windows with impact‑resistant glazing where state code requires it.

Representatives for the applicant explained a multi‑part rationale for replacement: some openings are larger than code thresholds for which impact glass is mandatory, some openings require reframing and therefore trigger the code, and there is long‑standing water infiltration that has damaged frames and flashing. A preservation architecture expert cited National Park Service guidance that impact‑resistant simulated divided‑light, custom wood windows can match the visual qualities of historic sashes when profiles and sight lines are equivalent. Commissioners asked for detailed jamb and sash profiles and confirmed the applicant had provided sample corners and mockups. The commission accepted the National Park Service guidance into the record and voted to approve the replacement approach and materials as presented.

Commissioners noted the tension between state building‑code safety requirements for coastal areas and historic preservation goals, and asked staff to clarify policy intersections for future cases.
