If the partners agree to specially allocate one item (for example, capital gains) 80/20 for economic purposes per SEE safe harbor, the corresponding tax amounts must also be allocated 80/20.However, IRS has a framework that can reallocate the partnership items based on the “ partner's interest in the partnership” if IRS determines the method of sharing the partnership items lacks the “Substantial Economic effect” (SEE) To meet the SEE, there are strict rules to maintain meaningful capital accounts including Deficit Makeup Requirement for those accounts.With the requirement, the partner must at some point contribute sufficient capital to eliminate the deficit, and the partner has the burden of the loss that partnership has and the allocation of the partnership will be respected by the IRS.This is a very high-level summary of the rules and is not comprehensive. there are many exceptions as well.Since the substantial economic effect, safe harbor allocation rules are complex and requires considerable additional recordkeeping, it's easier to follow PIP standard.

The unit I am living in is a 1 BR/1 BA on the second floor of the building...the door to the attic is right outside my entrance and goes up to a big open area that USED to be 2 additional bedrooms, however, it has been vacant for years as there was a fire in the 80's.My handyman took a look and agreed that he could definitely add the 2 bedrooms, no problems...I know egress windows will be a major factor and I am also looking into the heating and electric to make sure it is linked to my unit's heater/panel.What else should I be looking/planning for?
