I have been renting a commercial wherehouse in Los Alamitos California for nine years. Recently I found out that the landlord has been renting me this space Illegally. The building looks like a old air craft hanger. When I first moved in it was totally open. Then the owner divided the up into seperate units. After nine years of paying rent on time the landlord is giving me a hard time. Out of three other tenants I am the only one that he wants out. After three years I asked him if he had pulled city permits to divide the building. He told me and another tenant that he had pulled a general permit. Just recently though he is being investigated by the city for subdividing without a permit. I would like to move. Can I sue the landlord for renting me a space that has been illegal for years. I just went to reapply for my buisiness license and I was denied for the his violations. Can someone please tell me the next step for legal action.
