Not really common in the 1-4 unit residential space. 

I have a commercial property with four retail spaces and three different businesses.

Interestingly, the records do include the downstairs space as part of the livable square footage.

With about a bazillion sqft of vacant space now, and the tax revenue of the previously occupied gone. 

It took patience, being willing to rehab a house, and airbnb but we have our our own space and are doing great with only 2 bedrooms to rent out too.

Just make sure you are not installing this in lieu of linen closet if there's space restrictionsExterior: Landscaping, Fencing & Walkways: Don't have to spend a lot on landscaping but make sure yard is fenced, clear of debris,  private and secure.

I remember a buddy who once represented a client in the Santa Cruz Mountains.. this client turned an old barn into a shared art studio and invited local artists to rent the space, which ended up boosting inccome in ways they never imagined.The Redwood market can be tricky because of environmental restrictions, zoning quirks, and limited inventory.

Purchase price: $110,000 Cash invested: $2,000,000 399 Helmericks Ave includes 3 warehouse/shops totaling 60,000 sq.ft. and office space totaling 7,000 sq.ft.

I think I will need a car and an office space in the first few months itself.

I feel like it's a space where great operators can really clean up, since the bar is set really low, in my experience at least.
