Mold / Health Hazard in Rental — commercial landlord locked me out

I've been trying to resolve this on my own but I'm stuck.

commercial landlord locked me out. I've been dealing with this for about 8 months now and the situation isn't improving.

I have been renting for 5 years. My monthly rent is $1,650. I have a written lease.

Am I overthinking this or is this a real legal issue worth pursuing?

I've dealt with this before.

I ended up filing with the appropriate government agency, which cost about $4-8 but saved me a lot more in the long run.

I work in this industry and unfortunately this is very common. The good news is that when people actually push back with legal representation, companies usually settle.
