Litigation between the HOA and the builder appears to be becoming the rule, not the exception. In Forest Heights, most of the townhouse and condo developments are either in or past litigation with the developer of their units or have issues that the owners have been left to fend for on their own.
For the most part, it seems that the material is not defective, the installation is.
As an HOA member, even if your unit is fine, you go down with the ship if massive repairs are needed. In the case of the Riverpark Condominiums in Sellwood, the settlement with the builder actually put some money in the pockets of the owners once the repairs were completed and the building was better than new. They did live inside a tent for nearly a year though!
The HOA board president that I spoke with today hoped their settlement would cover 80% of the $55,000 average per unit repair estimate!
As an owner, you should keep everything that you HOA sends out. Buyers will typically ask for six months of HOA documentation and the latest budget and reserves to determine the health of the HOA. Management companies will often charge to reproduce what you have already received.
