What to do with a detached 572 sq ft garage?

[Ryan Duphorn]

I'm currently house hacking a single family home that has a 572 sqft detached garage in the backyard. I've already contacted the county planner and was told I'm not able to convert this garage to an ADU because of setback requirements. The setback requirements to build in my county require 80' minimum wide street frontage per this neighborhood zoning. My lot is actually only 75' wide but was grandfathered into the zoning once they made the setback changes (neighborhood is late 1950 builds). The garage does have electric ran with a small meter base. It's an A-framed garage with shingles roof, gutters, windows, and a 32" exterior door (in addition to a 16' operating face door). Any way to capitalize on this garage outside of just attracting higher rents once I move out and/or higher sales price if I decide to sell? Has anyone done anything creative in the past with a detached garage besides turning to ADU? The thing is huge and just sucks to have it sitting empty outside of me hanging out in there with a couple beers and a TV on nice days.
