Owner seeks waiver to convert carriage house at 89 Sagamore into third unit; board approves waiver and closes hearing

The Manchester Planning & Zoning Board on April 3 approved a waiver request so the owner of 89 Sagamore Street can convert an existing carriage house into a third dwelling unit without submitting a professionally stamped site plan.

Owner Cameron Armstrong told the board the work is interior and the carriage house exterior will remain largely unchanged; the planned internal layout includes a ground‑floor entry and living area with a second‑floor one‑bedroom unit above. Armstrong said the existing tree that limited parking had already been removed and that the applicant will expand the parking area forward roughly 9–10 feet to allow a three‑wide tandem layout and will stripe the lot to preserve maneuvering clearances.

Board member Bob Gagne moved to grant the professional site‑plan waiver and the board approved it by voice vote. The applicant confirmed two additional recycling/trash receptacles will be acquired and stored discreetly behind the building; staff asked the applicant to coordinate the precise location and to maintain the existing brick sidewalk in good repair.

The board closed the public hearing; staff will prepare the report for the next business meeting (June 18) and recommended the applicant return with any remaining details on parking striping, trash screening and window/egress adjustments required by the building inspector.
