Is this normal behaviour

My Mum sent me this photo of a baby GULL (thank you to Bob_Retired for identifying the chick)  to who has taken up residence on the garden wall of a house. The house is located on the Main Street so the chick is generating a lot of interest. The mother has been seen regularly coming back to feed the chick and check in. The lady who owns the house is constantly checking to see everything is ok and the chick is doing great. Is this normal to nest so close to people?
