Is there a leak in the bathroom, do I have the right to check out?

There is no right to check out, it is possible to ask them for repairs if there is no renovation.

If it's finished, you need to find someone to do the renovation to fix it.

There is no right to check out The statute of limitations has expired, and the property can be repaired unconditionally until it is in good condition.

This is too professional, the details are not very clear, but I think as a commercial house, since it is a commodity, you should be able to enjoy the return service within a certain period of time, I think as long as you take all the original purchase materials and all the proof to find the sale of the house, the developer should be able to negotiate to check out, but I think you should need to pay a certain fee, you can really find a lawyer and other experts to consult. Good luck!

Hurry up and deal with it, the sooner the better, you can mobilize other owners to build momentum, it is best to hire a lawyer, collect more evidence, this is no problem.
