Legal duplex converted to tri or quad

[Fernando Morales]

I am looking to buy a triplex or quad.

I have come across some legal duplexes that have been converted to either a triplex or a quad.

What are the consequences that could happen if I purchase a "nonconforming" property?

What instances might trigger those consequences?

For example, would I need to turn it back to a duplex by opening up a wall? What might trigger that? Would it be during the inspection period or maybe if I needed to get some repairs done in the future?

Most duplex zoning in my area is for 2-4 units anyway. So, is one of the potential consequences that I would need to convert the legal description to conform? If so, what does that usually entail?

Thank you for your input!
