Building Storage for Multi-Family Tenants

[Dustin Robideau]

Good Afternoon BP,

I'm looking into building storage units in the basement of a 10 unit multi-family I own/manage and wanted to hear if anyone has done this and would be open to sharing some advice. 

There's 3 completely empty rooms(unfinished) in the basement that I'd love to be able to monetize so I was thinking of building storage units and offering them for $45/month or so. 

Does anyone have any experience doing this and if so, is there anything I should be on the lookout for?

I'm mostly curious about:

- What to charge tenants that are paying between $650 - $800/month for rent?

- What size would tenants deem desirable?

- What materials would you recommend using for the construction?

- Any zoning regulations to be aware of? 

- Is there any reason this may be a bad idea or anything I'm not thinking of?
