Can renter sue HOA's property manager?

The harm was caused by the company who did the work. It would be unreasonable to expect your landlord or property management company to be at fault. Before you jump on the suing train your best bet would be to work with the property management company to get the vendors information then contact the vendor. They may have insurance that covers your loss.

It's a fairly standard practice for HOA's to require their vendors carry insurance.

Agree with the others. Did, by the way, Bill the notice about the work advise residents to move their furniture inside?? We do that for various things that must be one on the balconies of our high rise.

No matter what you should take lots of pictures of the damage as soon as you discovered it. I agree with all that said go to the Vendor first and then try the HOA. The HOA needs to know that a vendor that they hired did some very poor work. They should not be hired again IMO. It is usually required that only licensed and bonded companies get hired by HOAs in most States. If the PMC did not follow this guideline they may have some explaining to do to the board and the HOs.

Suggestion:

Have the owner of your unit get a copy of the HOA's contract with the vendor. MC must provide it to owner upon request. Look at the liability section of the contract. See what the vendor's insurance is supposed to cover and what's excluded.

IMO, you need to get a copy of the Notice which would have been emailed/and or posted onsite. These notices usually tell you the date & time which the pressure washing of the building would occur and in most cases, they ask that you move vehicles and outdoor furniture. If the notice asks you to move items and vehicles, you don't have much of a leg to stand on with respect to damages.

As these types of projects are approved by the Board of Directors and noticed prior to project start date, it would be on you to follow directions. For example, when the buildings in our condominium association were to be pressure washed, we were not only emailed, but notices were posted on all entry and exit doors as well as on our front door of the unit.

You can sue whoever you want about whatever you want; the property manager and Board of Directors are covered by the Associations D&O insurance, the vendor has their own insurance, the management company as well. Your unit owner/landlord/management company has insurance as well.

I asked Bill, too, Tamara, if residents were advised in writing to move their furniture indoors as they were in our high rise when the balconies were power washed and painted. He did not reply
