Only if you don’t want to be someone’s test case. Realize that Maine is filled with many many lawyers at all levels of government who are trying to stay relevent. A lawsuit to change laws and make them more open and more inclusive will hurt you bad. And it happens.
The Maine law clearly states that if an owner occupies one half of a duplex, the anti-discrimination law does not apply. Not even a liberal lawyer would go after the owner in such a case.
