I thought maybe I could just put a drop in sink instead but that sucker is like cemented in.

However, according to our By-Law/Master Deed, Garage is considered a part of "Limited Common Elements".Specifically, from our Master Deed: The Limited Common Elements of the condominium shall include any deck, patio, stairs, or garage to which there is direct access to that unit which is appurtenant to same, or any car port to which a Unit has been assigned....These Limited Common Elements are reserved for the use of the Unit(s) either immediately adjacent thereto or for the use of Units to which they have been assigned, to the exclusion of all other Units....Any expenses of repair or replacement relating to said Limited Common Elements, or involving structural maintenance, repair or replacement, shall be the responsibility of the Association, excepting for costs necessitated by negligence, misuse, or neglect of the Unit by a Unit Owner.One day, someone (not anyone I know) likely backed into our garage and crashed the garage doors.

Im going to be using job boxes cemented to the property and a shipping container as well as adding steel lock boxes to the bed of each truck.

The books provide a small bit of guidance and guardrails on how to do something, then I just do it and cement the learning into my brain.

The remaining 200 sqf I want to make a “loft/family room” that would be at the top of the stairs and lead into the master; also have beautiful views.

For extra eye grabbing attention and a homey feel I might add a small cement bird bath outside one of the front windows behind the Japanese yew bush.

There is also barriers to pouring cement as the only entrance to patio from outside is through the standard size door through garage.

Several discounted stores but I would not waist my time and gas money.Home Depot and Lowes have discounted items all the time that will completely do your job.Ask the Manager on Duty where the discounted items are .Most torn bags of tile cement are 50% off. 

I can't discern in the pictures of the sources mentioned if the brick is disintegrating or stair-stepping. 

Second story beam at the stair is sagging / deflecting.
