My extra 22X25' garage cost $17K back in 2006 I am sure the one the OP wants to do will be around 20K.
Agreed. Also, the OP should receive recent info on pricing within the last three years or so. I think anything pre-covid is pretty much irrelevant and not helpful, nor even close to what the price will be today. Pricing (materials and labor) also differ by region. And now the cost of fuel . . .But lumber, siding, wiring, garage doors, windows and concrete pricing is just ridiculous right now due to the current inflationary policies of the past 15 months and the Ukrainian situation.
