  Typical costs:
  • Having a contractor build a standard garage typically runs about $35-$45 a square foot. A small, single-car garage is about 240 square feet, or $8,400-$10,800; for a two-car structure it's around 380 square feet, or $13,300-$17,100.
  • AskTheBuilder.com[1] suggests that a "dream" garage with plenty of room for two vehicles (without having to squeeze to get into and out of them) plus adequate work space, lighting, ventilation and attic storage requires 800-850 square feet, at $29,000-$38,000 or more.
  • Upgrading the quality of materials can bump the cost to $55 a square foot, or $13,200 for a minimum single-car structure, $21,000 for a two-car garage and $47,000 or more for the dream version.
  • Accomplished do-it-yourselfers can cut costs considerably; materials for a single-car garage with a door but no windows start at $3,000-$4,000, depending on the size and style. Kits with pre-cut or pre-fab materials to build a steel or wood garage run $5,000-$14,000 or more, depending on the size of the structure and the quality of materials.

What should be included:
  • Most areas require building permits for garages. Consult with a local building inspector (it's free) before you start any work, even simple design plans. Depending on location, the cost for building permits can be relatively inexpensive or quite pricey.
  • Building a garage is a complex process that involves design, possibly demolition, excavation, site preparation, foundation work, framing and carpentry, roofing, insulation, windows, doors, eaves, exterior siding, electricity, ventilation and often plumbing. A general contractor will walk you through the process, hiring and scheduling subcontractors to do each phase of the work. ThisOldHouse.com[2] describes a garage project.
Additional costs:
  • Plans for simple or elaborate garages run $20-$200; the book Build Your Own Garage Manual[3] sells for less than $12.
Shopping for building a garage:
  • Do-it-yourself plans or kits are available through Archway Press[4] , FirstDayCottage.com[5] , HomePlaceStructures.com[6] , ABetterGarage.com[7] and ABetterPlan.com[8] .
  • Contractor referrals are available through the National Association of Home Builders[9] and the National Association of the Remodeling Industry[10] .
  • Get several estimates, making clear what is (and isn't) included in each quote; request and check references; ask about the contractor's length and type of experience, Be sure they're properly bonded, insured and licensed in your state[11] . See if there are any complaints with the Better Business Bureau[12] .

Contractor: Square Feet: 2 and 1/2 car garage
We has a garage built last summer and the cost was really good. Check into out the Springfield ohio contractors. It also depends on the price of lumber at the time the garage is built. Maybe you could keep an eye on the lumber prices and when the price is low hire a contractor.

Garage in Illinois
Amount: $57,500.00
Posted by: Shelley Maberry in Belleville, IL.Posted: June 11th, 2011 06:06AM
Contractor: Square Feet: 512
We have obtained 2 bids for a garage add on. We have a three car garage and want to add a 4th bay. The quotes have been $38,900 and $57,500. I believe that we will go with the higher bid, simply because this contractor explained all of the costs and the rationale for various steps in the process. He provided a detailed plan. The other contractor sent an email with no itemization. For those comparing cost, our add on will be brick, which accounts for nearly $10,000 of the estimate. Finished size will be 32 X 16.

Bids in, not built, may be my own general contractor to try to reduce price. Split faced block garage with brick front to match house. 40x26'. this is a dream and the dream is falling on hard times. One more bid due hope it comes in lower, or I'll have a big project on my hands. Already have finished concrete and electrical broken out. Hoping for $42K without those, then I'll move forward.

I got 2 8x8 doors with openers, a pedestrian door, and no windows. This job did not include electric or cement as I did that myself.

I have a 3 car carport that already has a poured floor and a closed in roof. The size is 24 by 28 and the contractor just has to frame up the sides and 2 8 by 9 openings for the garage doors and then put 4 plain vynal standard windows and 2 entrance doors in and finish out with vynal siding. It will not be finished out inside. Is this price too high?

Posted by: 99 in Derry, NH.Posted: August 12th, 2009 11:08AM
Contractor: Myself, BTD Construction of Derry, NHSquare Feet: 780 on two floors
Cost me $5800 to pour the 4' deep frost wall and 5-in. thick reinforced concrete slab. Cost me ~$1,700 to excavate the foundation myself, saving approximately $1,300 from what the contractor wanted to charge me to dig the hole, just rented an excavator from United Rentals. Contractor is local and priced extremely fair with my garage (non-foundation/slab) costing me $22,000 for the whole thing. I added a 4-ft. high knee wall on the second floor to make the floor to ceiling height in the "bonus" room upstairs in the middle of the room about 11'6" for a real bonus space.

Contractor: MyselfSquare Feet: 2000
In May '08 I started building a 34'x25' 3-car garage with finished floor above and an attached breezeway. There are some fancy customizations and "bump-outs" to make it look interesting. The only thing I have contracted out is the work for the foundation (17K) and the design (2K) and it will end up costing about 60K when I complete probably sometime next year. I would expect to have paid at least double if the entire thing were to be contracted out.

Garage
Amount: $33,800.00
Posted by: a user in Redding, CA.Posted: May 25th, 2009 04:05PM
Contractor: CarruthSquare Feet: 816
Costs are down due to the slow down in building, great time to build a gargage though. A totally finished out 2 car garage, side workshop, insulated door and over 300 yards so earth moved, 30 yards of gravel and 4 foot sidewalk in the front. We also have a permit requirement of stuco siding or fire resistant siding which may add to the cost, but we are in a fire prone area in N.Cal. Less than 30 days from start to finish for construction, 1 week of rain delay.

My garage was built in 1916 (at least half of it was-the other half was built later) and is falling deeper and deeper into the ground and is even starting to separate in one corner (we can see light). What should I do? Jack the house up and re-pour concrete? Brace the garage together somehow?
