Baltimore County panel allows window replacements at Oella duplex only after expert inspection

The Baltimore County Landmarks Preservation Commission voted to allow replacement of nine sash windows at 945 Oella Avenue — a contributing property in the Oella National Register Historic District — on the condition that the homeowner secure and submit a written assessment from a qualified historic‑window specialist verifying the windows are not original or are not repairable.

The property owner, identified in the hearing as Miss Frasier, told the commission the house is drafty and cold in winter, saying “the first floor does not get above the 50s,” and described air and dirt infiltrating the home. Staff had presented photos and measured window dimensions for nine sash windows, and noted it was difficult from the images to confirm whether the windows are original or early replacements. Staff recommended either requiring repair per Preservation Brief 9 and a repair scope before work begins, or approving replacement while citing Baltimore County Historic Design Guidelines and County Code.

Commissioners debated whether the windows could be restored or whether replacement was warranted. Several commissioners noted that some visible details — including smoother, non‑wavy glass in photos — suggested at least some windows might be later replacements, while others said the frames generally appeared repairable and recommended interior storm windows or traditional repair techniques as less invasive alternatives. Commissioners agreed that a site inspection or specialist report would provide the factual basis needed to decide whether windows must be repaired or may be replaced in kind.

The motion approved by roll call requires the owner to obtain a consultation and written report from a historic‑window specialist that documents the specialist’s opinion and basis for it (age estimate and repairability). If the specialist finds windows are original, the commission’s condition requires repair and restoration consistent with Preservation Brief 9; if the report concludes windows are non‑original or not repairable, staff may approve the proposed replacement without the applicant returning to the commission. Staff said it would provide recommendations of qualified specialists to the owner.

The commission’s action implements the commission’s responsibilities under Baltimore County historic design guidelines and County Code and preserves the option to require repair where original historic fabric remains. The commission did not approve tax credit funding itself; the decision addressed eligibility and certificate‑of‑appropriateness considerations tied to a Part 2 tax‑credit review. The commission recorded the roll‑call vote in the meeting minutes and will expect the specialist report to be filed with staff as the next step.
