Hi, I am a non U.S. citizen and I'm currently renting a house in Pacifica, CA. The owners have taken the downstairs bedroom and drywalled it off to create a separate suite to rent out to another tenant, there is a separate entrance, but we share heat, power and water. Our concern is, is this a legal setup in terms of fire codes as well as residential building codes? We tried contacting the city, but received no response. As well, our landlord gave us an option to sublet the extra suite ourselves. As non citizens, is this legal for us to do, or will this put our Visa at risk?

Thanks in advance for the information !

Also, where else can I find information on this? I would like to have all my bases covered.

Much appreciated !
