Others are truly in financial hardship.My own thought is that the next needed step is a moratorium on loan payments, some kind of forced loan modification such that rental property loan payments missed due to tenants experiencing COVID issues would have the loan put into forbearance and the missed payments "added on to the end" with "balloon" "due dates" being adjusted as needed.The mistake most of us make is that we expect the government to work out the details (everything that flashed through your mind reading the prior paragraph).

Here's a modification of what you are thinking of doing. 

It appears you are doing the Standard 203k because your project is min $5k and/or requires structural modifications. 

Coastal stuff built in the 1960s had none of the earthquake and geotechnical requirements we have today, and parts of the coastal areas present challenges (I'm doing a project about 4 blocks from the water now that happens to be in a liquifaction zone, necessitating plenty of soils work, even for a small addition).I guess my only other comment is the use of the "construction crew" ... that's no small feat at the moment. 

If i were to add an additional furnace, i would connect each tank individually. along with the info from @tim holmes, the furnaces may need additional modifications for the size of the apartment.electric may be a good way to go. thanks

Obviously we will be making modifications based on our own specific agreements.

Have any of you done this type of modification before to a small multiunit prop?

Initials: _______Modification – Landlord reserves the right to make reasonable modifications to this lease and to Landlord’s rental policy from time to time.Hope this helps and I look forward to reading the additions to this thread!  

The County Fire Department will allow a 13-D system with no other upgrades or modifications.  

I looked at the property records - expansion would be possible but would necessitate the purchase of an adjoining property.
