Regretfully, Geico will not cover unless you have coverage for special assessments.
Now let's say you had a leak in your unit, then Geico would cover, but since it is a leak in the building that is being Pursued by an attorney, who is going after the builder and in the mean time the repairs are being paid for
By a special assessment, slim to no chance.
Also, hopefully the builder has enough insurance to cover the cost of all repairs as it is not uncommon
For builders to file for Chapter 11 or close down, the lawyers still have to be paid.
