Check this "howto for finding the AddOns directory":
https://www.esoui.com/forums/faq.php..._howto_install
And then replace the AddOns in the path with SavedVariables.
In this folder then you'd need to find the SavedVars filename for the addon, probably EssentialHousingTools.lua (should be the same name as the foldername of this addon inside the folder AddOns!).
Be sure to LOGOUT on PC1 so the SavedVars file is saved properly.
Copy this file to the other pcs SavedVars directory (logged out on pc2 during this as well!!! or it wil lbe overwritten again).
Then login on PC2 and it should have the data if you are playing with the same Account names on the same server.
