JP data centers had their auto demolition paused from July 30, 2018 - Jan 7, 2019. NA data centers had their auto demolition paused on Oct 24, 2018. Going by that same basic time frame, the NA data centers should have their auto demolition resume some time in April. Probably pretty close to the April 23 data center reshuffle, since we haven't had an announcement for it yet, and they announced the JP data centers starting back up a month before it happened.
FFXIV has had quite a few influxes from WoW being bad. Just because we've had a new one doesn't mean they're going to change how they treat auto demolition. It normally lasts about 6 months to try and let people get their lives back together. Keep checking for random people leaving the server and demolishing their house, see if you can get lucky. More than likely, you won't have much chance until April after the server shuffle.
