The City of San Diego is soliciting bids for restoration of the Mohnike Adobe and Barn, two historic structures requiring structural rehabilitation and seismic stabilization, with proposals due October 6, 2026.

The adobe restoration scope covers a 2,512-square-foot structure requiring site drainage improvements, water and gas supply upgrades, plumbing modernization to current code, foundation repair with retention of historic fabric, temporary wall stabilization, pest management, adobe wall repair and in-kind replacement, roof structure seismic stabilization, north and west porch restoration including decks, foundations, columns and stairs, interior finish restoration, and reconstruction of the original east-facade lean-to. Site work includes removal of concrete walkways and replacement with decomposed granite to allow adobe brick walls to breathe, courtyard drainage system installation, one additional parking space, and a path of travel to the building.
The barn restoration scope covers a 1,408-square-foot structure requiring seismic stabilization of foundation and wall structure, south wall reconstruction, wood floor repair, wood plank siding replacement, crawlspace vent reconstruction, drainage swale improvements, pest management, north entry door repair, roof panel and hay mow door repair, eave assembly and bargeboard repair, rafter end and skip sheathing repair, exterior painting, and restoration of the track and pulley system to working order.
