I begin work on the household network by removing CATV coax cable plates (which were screwed directly to the drywall) and installing old-work junction boxes that have been modified to accept conduit connectors. ($36.22)

I continue work on the household network, installing junction boxes and running conduit.
I also purchase a couple 4′ x 8′ sheets of drywall ($13.68) as a test to see if they can fit down the staircase and turn a tight corner into the lower level. The sheets make the turn, but just barely. The stairwell walls will need new paint.
My application is approved and I purchase a basement remodel building permit for the remaining work on the house. ($540.06)
Ice dams continue to worsen and melt water continues to seep through the drywall and damage the bedroom ceiling. I strongly suspect that there is more to this than meets the eye. Unfortunately, I will not be able to address the root of the problem until spring at the earliest.
I added a conduit connector to the rear of the exterior cable TV service box and connected it to the new household network conduit.
At some point the house had a gas fireplace. The flipper took it out, but left the gas line and shutoff valve in the basement ceiling… hiding it behind drywall. I remove the orphaned gas line and shutoff valve and capp-off the black pipe junction. ($2.41)
I also find and rewire an ungrounded AC outlet. ($8.22)
Per building code, I install two new wired and interconnected smoke alarms. ($64.78)
I accidentally dropped a new, unopened can of Great Stuff insulating foam and the sidewalls of the can rupture, exploding its contents all over our partially-demolished bedroom. I scramble to contain the spraying can with my hands and get it out of the house, but it’s too late. The foam ruins tools, walls, and carpeting.
The city building inspector signs off on the construction work that has been done to date. Also, I remove some legacy phone jacks, patch the holes, and install a few more junction boxes for the household network.
I continue working on the network conduit project, adding CAT6 cable as I go from room to room. In some places, CATV coax is in the same conduit.
