54 Mono Street Apartments

The 54 Mono Street Apartment Project was approved by the Planning and Economic Development Commission on October 8, 2025. 

Use Permit 24-003, Major Design Review 24-006 and Adjustment 25-005 were filed to allow for a six-unit, multi-family residential apartment project subject to the Town’s Density Bonus Ordinance located at 54 Mono Street. The project is categorically exempt from CEQA pursuant to CEQA Guidelines §15332, In-Fill Development Projects. .

The proposed apartment project consists of six (6) multi-family dwelling units within a single structure located in the Residential Multi-Family 1 (RMF-1) zoning district at 54 Mono Street. The project features one level of understructure parking for seven vehicles and an exterior parking area for three vehicles. The application includes a density bonus request to permit double density on the site for three additional dwelling units through the Town’s Density Bonus Ordinance. The density bonus request requires a minimum of three of the six units to be deed restricted for workforce housing; however, the applicant has agreed to deed restrict all six of the units for workforce housing in exchange for four concessions (1 automatic concession and 3 additional concessions) to the applicable development standards as allowed pursuant to the Density Bonus Ordinance. The requested concessions include: (1) an increase in the allowable lot coverage from 50% to 60%; (2) a 20% reduction in the rear and side yard setbacks; (3) the reduction of one guest parking space to allow for a total of two guest parking spaces; and (4) waive the requirement to provide 60 square feet of private outdoor open space for each dwelling unit.

Planning and Economic Development Commission Public Hearing - October 8, 2025 

A public hearing for the 54 Mono Street Apartment Project was originally held at the August 13, 2025 Planning and Economic Development Commission meeting, however because of public comments pertaining to snow storage along the rear property line and confusion regarding the 30-foot-wide shared access easement along the northern property line, the item was continued to October 8th, 2025. The project was then approved at the October 8, 2025 Planning and Economic Development Commission Meeting.
