Hello Dawn & thanks for contacting me.
Having windows that don't open in a residential living unit on a first floor bedroom like an apartment is usually not common, except is some highrise buildings. I am not an attorney so I don't want to express legal or not. In some apartments it may be allowed where there are windows that are fixed that don't open. Any new construction building more than likely would require a bedroom window to open or some other means of escape in case of fire. You should consult your local municipality for their local code in your area.
Thank you and have a good day.
