The Mosby Building

Summary

The Mosby Building is a seven-story office building at 10560 Main Street, originally constructed in 1964 as a multifamily residential building. In 2014, City Council approved a proffer amendment permitting office and some non-office uses on all floors. The site sits on approximately 3.25 acres, zoned CR Commercial Retail with existing proffers in the Transition Overlay District, and designated Commercial Corridor and Green Network Public in the Comprehensive Plan. The proposed project would convert the building back to mixed-use, with 107 multifamily rental units on upper floors and ground-floor non-residential and 'live/work' uses. The applicant's stated rationale is that roughly 65% of the building's floor area is either vacant or soon to be vacant, making now an opportune time to reposition the building. As of the most recent activity (City Council work session, September 1, 2026), the project remains in the pre-application/concept plan phase and no formal application has been submitted.

Open questions & options on the table

• A formal application has not yet been submitted; submission and formal application review are the explicit next step.
• The working arrangement between management of the proposed rental housing in the Mosby Building and the existing adjacent condominium ownership housing (shared access points, parking, and common infrastructure) has not yet been finalized and is to be worked through during the review process.
• Outreach to existing businesses/tenants in the building by the new owner/applicant was raised as a question during the July 27 work session; the status or outcome of that outreach is not recorded.
• Adequacy of parking and infrastructure to serve both residential buildings was flagged as a matter to be confirmed through the process.
• The building's name is expected to change at some point, but no new name has been determined.
