Contractor Garages - how many units per acre is standard?

[Ian Dunross]

Hi everyone,

I'm starting my research into contractor garages. I have 6 STRs and I'd like to transition into light industrial real estate. 

Is there an industry standard number of 1200-1500sq ft contractor garages that can fit on an acre? I don't want them to be too cramped, in case some tenants need deliveries via semi-truck. 

Thanks for any info!
