Angela Lopez' house is not seen in season 1; in season 2, episode 1, Wesley Evers has moved in with her (and they obviously have different views on housekeeping). They welcome baby Jackson and get married some time after Lopez is rescued from Sandra de La Cruz (La Fiera) in "Life and Death".
Sergeant Grey says to Angela Lopez on her last day before her second maternity leave, "your house is five minutes from here (the station)"; aside from this there is no other mention of the location of the house in the show.
