Learning how to build a garage is not as daunting as one might expect, at least for discrete structures. Homeowners who build their own garages can save thousands of dollars instead of hiring a builder, and in many cases they will subcontract to the same construction workers you can hire. Or, if you're adventurous, or just downright frugal, you can invite friends to have a few beers on the weekend and let them go to work.
In the early planning stages, there are many projects to consider, such as:
Garage size: One car, two cars, or even three car garages can be designed in a variety of sizes, but the budget for the lot and homeowner is usually the limiting factor. Local building codes vary, but usually a building must not encroach on an 8-foot property line in rural areas and zero to four feet in the city. The detached garage must also be at least 8 feet back from other buildings, but this must be confirmed by the local building office as the budget varies. An important consideration is the roof overhang. The eaves and gable end drape are usually 12" - 24" [although usually less than 12" in windy areas] and must be considered when determining the size and location of the building.
One way to determine the perfect size is to add 12 and 15 to the width of each car. If you plan to use a side wall for storage, each side requires an additional two feet of width. The length should be at least 22' and add 4 to 10 feet of workbench and storage space. A two-car garage can be calculated as 2 x 12' + 4' stored along each wall = 28' x 22' no workbench. Common sizes include:
1. One car: The normal garage size includes 12'' 14'''''''' ' If you have a full-size truck, the length of twenty-four feet is almost the smallest, even for small or medium-sized cars, there will be a small swing space of twenty or twenty-two feet.
2. Two cars: The most common garage size in many states and provinces is 24&x; x 24' because many building codes require engineering drawings and structural engineers to perform two inspections of concrete floating plates [single pieces] larger than this size. If the space is scarce and the size of the two cars is small to medium, the width may be sufficient, but it is certainly uncomfortable.
3. Three cars: With more design space and three garage sizes, homeowners tend to have larger budgets when considering these large construction projects. Common sizes are 36' - 42' extensive 26' - 30' long.
Foundation: Floating panels [single] and panels with frost-resistant walls are the two most common base choices. Floating panels are cheaper and easier to build, but usually require drawings and two inspections for larger concrete slabs [ie 24' x 24']. In cold climates, many contractors install 2.5" base foam under concrete to reduce undulations during freezing and thawing.
Adding 6' x 6' #10 wire mesh is an inexpensive way to increase floor strength and reduce concrete cracking. Most contractors install 12" - 16" thick thickened concrete surrounding floating panels around the perimeter 16" - 24". Adding two rows of #4 bars will increase the edges. Concrete strength should be at least 3,000 psi, and many contractors use 4,000 and 4,500 psi because the extra cost is low. Another consideration is the use of fiber webs to order concrete, macroscopic synthetic fibers for secondary reinforcement of concrete. Local concrete suppliers can add it to the concrete. The thickness of the slab depends on the strength of the concrete and the reinforcement design, but a good rule of thumb is to cast a slab of 4 inches or more.
The minimum depth of the frost wall is determined by local building codes, typically 48 inches in cold climates and 36 inches in milder areas. Once the trench is dug, a foot of approximately 12 inches wide and 8 inches thick is formed and spread, and the keyway is etched over the length of the foot to prevent movement of the concrete wall. A frost barrier is formed and poured onto the foundation, and anchor bolts are mounted therein to connect the wall to the foundation. The concrete slab is then known for its design thickness. Obviously, this basic system requires more time and expense.
Wall structure: If the garage is now insulated or may be insulated at any time in the future, the size of the wall studs is important because the 2" x 6" studs allow for more insulation to meet building code requirements. [For garages with apartments] instead of 2" x 4" studies. Of course, the 2" x 6" studs are stronger, which results in a more structured sound construction.
Wall height: The walls are generally 8' but 9' and 10' walls are common. In the downtown area, the height of the structure is usually limited, for example, the average height of the four corners measured according to the slope, and the roof peak is less than 16. This means that if the garage is located in a bank with concrete curves or retaining walls and backfilled to the top of the retaining wall, you can get a little extra height. Another way to maximize height in these areas is to pour 12" concrete curves around the concrete slab and backfill the soil to the top of the curve and grade it from the structure. Height restrictions [confirm that this will be the local building office before implementation] This strategy].
Garage door placement: Garage doors can be on the gable side or on the eaves side. Some things to consider:
Existing house designs may determine the direction of the roof line. One method of assisting visualization is to take a photo of the house and include the area in which the garage is built. Use the gable and eaves options to print two photos and hand-paint them in the garage.
2. If the garage will be built in a cold climate, the garage door at the gable is a better design as the snow will slide down the eaves.
3. The flexibility of the garage door at the gable end allows the height of the future car port.
Roof style: The roof style is usually determined by the existing house, for example, if the house has a hip roof, this will be a good choice for the garage. If this is a DIY project and the homeowner is building a garage, it should be noted that the hip roof is more difficult to construct than installing a standard truss. Roof spacing must also be considered, which should normally match existing homes. Due to the increased possibility of water leakage, it is not recommended that the roof spacing be less than 4/12 [4" per 12" stroke or length]. A higher pitch roof with a specific truss design can allow storage, lofts, and even apartments above the main floor. The most common roof trusses for garage roof design include:
1. Standard Fink: This is the most common residential truss.
2. Double fins: Designed to handle high weight loads to meet higher snow loading requirements.
3. Attic: Applicable to designs that allow storage on the main floor. The access can be a stairway or a loft down stairs, and the options available may be determined by local building codes.
4. Scissors: This option provides a cathedral [vaulted] ceiling that provides more interior ceiling height. For example, the 24' x 24' 8/12-pitch garage center can have a ceiling height of 12 inches and an 8-inch ceiling height of 8 inches. on the wall. The system is typically weighed with buildings with conventional pleat trusses and taller walls.
If this is a DIY garage project, don't forget to order two gable trusses for each gable end. Otherwise, two conventional trusses will require wood filling to join the jacket and siding [not to mention, the building inspector may not pass the frame inspection. Sheath. This is the only way to meet many attic insulation level requirements [ie R40].
Garage plan: Once you have decided on the above project, you can get a building permit application and a builder's garage plan. It is important to get a high quality garage plan that is easy to follow, accurate, and provides a bill of materials [well, the bill of materials is not important, but it will definitely save a lot of time]. Several websites offer garage programs created by dozens and hundreds of different companies, so consistency and quality control need to be kept in mind. Several companies have their own internal drafting, and the search for the Internet should find these companies. Another option is to hire a local draftsman to develop a garage plan.
Plot [plat] plan: The Building Compliance Department will require the drawing display [site plan] to have an existing structure, a proposed structure and a plot of attribute lines, where the measurement indicates the distance between the attribute line and the structure. This can be a hand-drawn drawing of a marked copy of the drawing/platform plan. The construction department may need to conduct an investigation to confirm the accuracy of the measurement required for accurate garage location.
Building permit: Make an appointment to meet with the building inspector, discuss the project, and submit the garage plan, bill of materials and site plan to the building department. A building permit can be issued at this time, or the building inspector can take several days to several weeks to review the documents.
