When you price out a garage by the square foot are you using the square footage of all wall-space, as in all surfaces to be sided?
I priced out a garage but I don't usually use sq foot to price my jobs. new construction is sort of new to me.
Thanks!
If you've not done it before, square foot pricing will get you in Trouble, with a capital "T".
It is usually only used as a rough guide AT THE END of the bid process. It can tell you if you've forgotten something... or if something is high out of whack. At the end of the day, there is no magic square foot number that works for every builder on every garage... or house... or kitchen... or... etc. etc. etc.
I'd be very very cautious when pricing a project you don't do very often. It's far too easy to leave out a line item and kill your margin.
To answer your question, most square foot references in regards to new construction buildings refer to the footprint of the building.
