If you live rural, often there are zero codes to worry over or permits to obtain in a huge percentage of US area and population. My retirement home is going to be zero expense for heating and cooling on a fixed income while utility bills edge towards $1000/mth for humblest digs.....i will be plonking three conexes side by side and locking them together at corners as designed....thick poly sheet wrap, cut any doors or dividers wished, likewise wall and floor covering...whatever...standard windows and double doors in airlock config, standard drainage culvert in front of each window, and burying it under fill dirt and then topsoil, utilities run through pipe...earthquake and tornado proof with flipdown or slipdown lids for window culvert (probably manhole covers)while staying 72° year round....only utilities will be for appliances and lights....and no financing anything....pay as you go....
