New Garage Cost Per Square Foot?

wildpasturesFebruary 2, 2007

Hubby and I are planning to build a new 3 car garage with workshop area for him. We're trying to estimate costs and some of what I have seen scares me (cost wise). We live in the Mid-Atlantic area outside of major metropolitan areas. Anyone care to give a ballpark on full construction cost per square foot (from foundation to roof singles)? I realize it will vary but looking for approximation on an everyday type garage without any bells and whistles.

I am in the process of building a home. All of the builders have given me a average rule of thumb of $55 per square foot. A basic three car garage will run in the $44k range. Most are 24x34

We built a 2 car 2-story workshop with a 2 car garage door and we paid $38,000 and that was with can lights, powder room, and wall mount heat & air.

I had a garage 26 x 30 built last summer for $25000.00. Contractor did excavation,concrete slab, all steel building with man door, insulation, two windows, and two garage doors. Electrical was done by myself, about $1000.00 in material, and trenching.

Am completing a 24 x 34 right now (metro Charlotte, NC) with vinyl siding and brick facade on partial slab and crawl with private office. Gareage area suited for 3 car storage or 2 car storage and game room. Concrete work with foundation, crawl, waterproofing, infill (140 yds of fly ash), compaction testing, 6" concrete slab, stud walls 16 OC, 200-amp 6 circuit electrical, architectural shingles, siding and brick total of $30K or $37/sf. I still have to finish interior walls to my specs.

If you are in this area and need a good link to a contractor, post it here

I'm building a 24x26" bermed into the hillside with full concrete below and living quarters above. I'm approaching $100/sf and still have the interior trim to go. $20K in excavation and $18K in concrete was necessary because of site conditions. Normal site prep and foundation would be one-tenth of that. I also have a solar-tube in the bath, an air exchanger, a 225A service with 240V up and down, and some other extras. It is, of course, the "little" extras that add up fastest.

Buy a copy of the "Means Cost Estimator" from your local mega-hardware store. It's used by contractors to bid on projects. It us updated yearly and contains regional calculations for different parts of the US. My concrete sub was within a few dollars of the Means estimator. The roofer was high, and I told him. He dropped his bid $1,000 just based on me saying he was $1,000 high.

My guess would be that you won't get under $50/sf unless you do a lot of the work yourself and keep things simple.

Wanted to say thanks to everyone for their responses. We've gotten a few quotes but are very disheartened at the lack of response we've been getting from builders in our area. I can't believe that in over a month I've only been able to get two out of six responses. Those who have responded have given me quotes that are more than the cost of the original house. (One came in with 165k!!)

At any rate, I've given up the idea of any type of enclosed connection to the house, as well as storage space upstairs in the garage. Just too darn expensive. Three car garage, good size workshop area is all we're looking to do now with electric and a plumbing rough in. Anyone know a decent contractor in Northern MD? Have cash will travel :)

I'm wondering if the people on the post from Charlotte could pass along the names of the contractors they worked with on their projects. I'm in the process of having a 2 car garage addition quoted and would love to know who did those projects so I could contact them.

Probably a long shot, but does anyone know a contractor that would do a similar project in central Mass? I would love to get it done for less than $50/sq foot!

These prices just amaze me.

We just built a new house. We added an attached 44' x 26' drive-in workshop with 10' high, 12' wide doors in both ends, insulated and fully finished inside, for about $50K over the price of the house and garage alone. That included a metal roof, cement board siding, four high quality casement windows, one interior door, and a separate 200 amp sub-panel. There is only 26 feet of common wall on one side.

It worked out to just over $43 sf.

Just had a 30x36 detached 2 story garage with 3 garage doors, two dormers, and full storage attic built in central NC. We opted for lots of large windows to match the house, had to get tempered windows for the side with the interior stairs to the attic, and had a full block foundation. We had concrete poured in the garage and also had about a 35x36 concrete slab poured in front of the garage with a large retaining wall and re-routed our driveway with new gravel. We needed lots of back fill and needed a slight grade on the pad for drainage We hired out for grading, labor, and concrete. We did the retaining wall by ourselves. We bought and customized the materials garage package from Builders Discount Center. The total end cost was $35,000. Happy to give referral recommendations for Chatham county are in NC.

I live in Oregon and I've been qouoted about $80/sq. foot for a garage/shop with a bonus room with bath over. Seems high. I realize this discussion was started back in '07 but does anyone know how much the going rate is for something like this. We dream of having it done for $40K but have been told expect it to be closer to $60-70. Thoughts?

After reading the posts I'm still not sure if I have a handle on cost differences between adding a detached or attached garage/shop. I haven't nailed down what I'm going to do yet. I currently have small shop (inadequate) in the back of an oversized two car attached garage. The garage is on the left side of the house. I'm considering extending out toward the street with two doors again facing the street. I'm also considering extending out for a three car with right side facing doors. A third consideration is adding a single car garage with shop to the right side of the house. The first two options allow me to turn the old space into half shop half game room.
I'd love to get a ball park figure on all three to see the impact on pricing. In any case I will be doing the electrical and the interiors. I hope I have'nt jumped off topic here.

I currently have a 2600 square foot garage w/about 1700 sq ft additional on the second floor. My father in law built it 30 years ago. I can't believe how much it would cost to replace it at current prices! In fact the county doesn't allow detached garages this size anymore.
