Are all maintenance requests required to be fixed?

[LaMiracle Schaefer]

I’ve done a bit of research on what’s required or not by landlords to fix. However, can landlords deny to fix issues that may be deemed cosmetic? Ex. A home has wood tile flooring. A few of the tile pieces slide slightly just because of how they are clicked into place. Would this be necessarily considered something to fix? The only solution that would seem appropriate would be to replace the flooring completely. However, it’s habitable and not a hazard.
