A lot of it would depend on exiting, isle placement, types of refrigeration, full or limited meat department, bakery, etc.Even the large grocers like Albertsons can't estimate a cost per square for a store buildout unless they've designed and constructed the buildings to their specs.Unless you're dealing with an experienced contractor who has built out multiple grocers, I doubt you'll be able to estimate a buildout cost.This type of capital improvement is just to large a component of leading costs so my advise would be to spend the money and have an architect layout the store, they don't need to draw up plans just yet, and then find a qualified contractor, or two, or three, to bid out the job.

A little about me… I’m 42,single, college graduate, former retail store owner, long time renter in SouthOrange County, Ca. and actually do enjoy long walks on the beach.

I spend an hour or so each day running to the store to buy stuff at the last minute.  

In our area, if the property is vacated the landlord must pay for the stuff left behind to be stored for 6 months.  

Yesterday I found a letter with their keys in my UPS store mailbox, which I only visit once a week, dated 4 days ago.Of course, my lease says ALL of those things.

A healthcare REIT maybe different than a U-Store It REIT. 

Putting the store front aside for the moment, that's $200k on $1.2mm investment.

The caulk will dry, shrink and leak over time.I have used window replacement companies with long track records and supplier warranties not the big box stores because the do it every day. 

After a couple years gaining great introductory experience, I accepted a position as a property manager for a real estate firm headquartered in Denver.My primary professional focus is related to managing and leasing various types of industrial/warehouse properties in CO, AZ, and TX.
