You are working with a "loaded" gun here, mold issues and a Tenant. Regardless of everyone's advice, you still have to read up and educate yourself on Local and State Codes. And, consult an expert/Mold Remediation attorney.
Me: Landlord, Owner, Property Manager (of my holdings), Contractor and Certified Mold Abatement Professional -- among a few other trades.
I have a professional drafted Lease with several Required Mold Clauses and Addendums each tenant must Read, Initial and then Sign the lease too.
Points: When a tenant "asks" for a "Mold" test, they are really asking for A Trained Licensed Professional to Collect Samples based on the Size (Square Feet) and Scope of the Infected Space.
Then this professional hand off the samples to a LAB for evaluation.
Some test test the air quality and all occupants have to leave for a 24 to 48 hour period.
If the tests comes back Positive, you are in a WORLD OF HURT! From that moment on, forever in your ownership, you have to alert all Tenants, Guest, Workmen, Cleaning Crew and other, that in Unit number 12, under the kitchen sink, mold was found and was treated. And you received a clean bill of compliance.
That means the next time you want to show another vacant unit to applicants, before they enter your building, you have to tell them about Unit #12' past mold problem.
(Just a cute note, when Section 8 said I HAD to Allow Section 8 people with Vouchers to look and rent out a unit in my 19 unit apartment property, I made all people wanting to enter the building that the Lady in unit 6 died and MOLD was found in her unit! -- then all Section 8 trash runs away, and I'm saved).
Hotel. Rules are here in my State, you do NOT have to Pay so much as 1 cent towards your tenants temporary accommodation, instead you just s top charging them their daily rent.
Next: Before I rent out any vacant unit, and after I fixed/remodeled the place up, I conduct a Mold, Lead Paint and Asbestos Test.
Every 3 to 4 months I conduct an inspection of each unit. One unit that is rented to a 70 year old couple had mold growing all over the kitchen sink. Each of the couple refuses to clean up after themself or their spouse. I also found mold growing around some of the stove burners. I gave these tenants a Booklet, cleaning supplies, gloves and a M95 mask. I told them to clean up or hire someone to do the clean up for them. Instead they filed a complaint with the County Health Department, while I then filed for an eviction.
My lease read that tenant are responsible for cleaning after themselves and keeping their rental habitable.
So in this case my tenants, with the City's help filed a lawsuit against me for damage to their health. I then informed their kids and grand kids that their unit if Toxic and they can no longer visit. Last night (from when this happened so time ago) my tenants had their infant grandson, grand daughter and dog over for an overnight stay. So if my rental was really toxic, no sane person would have done that.
