They are not the same thing, but if the building was constructed prior to 1969 without undergoing a change in occupancy type and no major renovation permits pulled, it will likely not have or require a CO.

I currently have a SFR undergoing renovations that should be complete by mid-August.

and the rest of the landscape would undergo a gradual change.

I'd prefer to invest in a B area or an area undergoing new growth - I'm planning some trips up the coast to explore both cities.

We were told the house was undergoing renovation and it would be leased after completion. well, after a few emails and the assistance of one of BP members we found out the house is actually occupied..

Or, if we deem necessary, if the tenant has caused problems in the past or has a history of late payments, we will then issue a non-renewal notification and begin to market the home for new applications which will then undergo our screening process. 

To refi now or wait...I am at a point where I am about to refi a rental property in Reseda, California that is undergoing construction of a garage conversion to a ADU.

Also, Brookland Park Boulevard is undergoing a transformation near Chamberlayne Avenue that may help Highland Park as well.Still, I don't like to bank on appreciation with real estate investments and I don't think that the housing stock in Highland Park will lead to the high end renovations going on in surrounding neighborhoods.

Many of these neighborhoods are undergoing gentrification, which means the housing market is going go up. 

I ask because this property is currently undergoing renovation and doesn't appear to be a tear-down.
