Look into cleaning with strong products or a vinegar and baking soda mix the windows and doors, specially the frame area where it might not be painted.

Another remedy that I read about was using commercial grade vinegar 15% , it is acidic and will kill the bamboo , but it cost $ 600 per 55 gallons .

Making sure they are run at least periodically to keep them running well and fresh (use white vinegar to remove odors).

Tenant may be able to keep drains clean and clear with regular maintenance by pouring down the drain a quarter cup of baking soda followed by a half cup of vinegar.

Good advice from others here, I would also add....Use white vinegar to clean up the wood, as it will kill the mold spores in porous surfaces such as wood and will also deodorize it.

If it's the latter, you really may want to pull up stakes & move on and find a municipality that's a bit easier to work with.When faced with this situation before we once went the route of a co-op and got the city to turn from being against strictly "self storage" to working with us and even providing grant money.My general advice is probably what your mother told you: "You catch more flies with honey than vinegar."

More bees with honey then vinegar.

It worked alright, but it was white vinegar that did the trick of getting rid of the smells.

I once pours undiluted white vinegar on one such and the surface bubbled like acid, but it removed it and after some additional cleaning it was back to new.

It is likely you will garner getter long term service being honey rather than vinegar.
