A: First, fire-rated systems are only required if the garage shares a wall or a ceiling with the home. If you are doing repairs in the garage you should replace with like materials, but remember it is the wall system that is fire rated not the product itself.
Houses, garages or sleepouts within 1m of a defined boundary are required to have a specific designed 30 minute firewall.
Exterior walls generally have a rating based solely on interior occupancy use and structural requirements. However, exterior walls that are 10 feet or less from the property line are required to have a fire resistance rating based on the proximity to adjacent buildings and interior occupancy conditions.
Conclusion. In short, the garage needs to be separated from the house in case of fire, but this isn't a fire-rated assembly, nor is it a firewall. The best term for this required separation is a fire-separation wall.
Yes, you can use drywall in an unheated garage. The drywall doesn't mind the cold. I usually get asked the opposite question: Can I leave drywall off of the garage walls? I don't recommend leaving it off, but I let them know where the code requires it and where it can be deleted. In the US, IRC table R302.

You'll likely need a permit since this project may require soil grading to avoid drainage issues. Repairing your floor may be more cost-efficient than replacing it if grading is necessary. No permit may be required to hang drywall on exposed wooden wall studs in your garage.
If you have a garage attached to your home, it is very likely that the swinging door between the garage and the house is required by code to be a 20-minute fire door assembly or the equivalent.
The majority seem to agree that insulated, unheated garages, should be allowed to breathe. If the garage is heated, you will need a vapor barrier, otherwise you will get frost and mold.
Common areas where fire-rated drywall is typically required are multi-family residential buildings, commercial structures, hospitals and healthcare facilities, educational institutions and high-rise buildings.
These walls will typically have a 2 to 3‐hour fire‐resistance rating. So what is the difference between firewalls and fire barriers? Basically, firewalls are thick exterior walls with a higher fire-resistance rating, while fire barriers are interior walls with a lower fire-resistance rating.
1. Fireblocking is required at ceiling and floor levels, and between the top story and the roof space (provided by the wall plates in platform framing). 2. Walls furred off the foundation require fireblocking every 10 ft.
Approved Document B (ADB) addresses fire safety precautions that must be adhered to in order to safeguard the safety of any occupants and personnel within the building. This includes the external walls as combustible materials have proven to assist in the spread of fire by enveloping the building.
People commonly misuse the word firewall to refer to the wall between the garage and the house. The wall between the house and garage is actually called a fire separation wall, not a firewall. A firewall is a fire-resistance-rated wall. It extends from foundation to or through the roof.
In wood-construction, most interior walls are bearing therefore require the 1 HR rating, however, walls within dwelling units are not classified as fire partitions, fire barriers, etc unless they are part of a corridor, dwelling unit separation, etc.
There are three options that makes a good fire-rated door: A solid wood door not less than 1 ⅜-inch thickness, solid or honeycomb-core steel doors not less than 1 ⅜-inch, or 20-minute fire-rated doors equipped with a self-closing device. A major part of the garage that needs to be fireproof is the garage flooring.
No 'need' to insulate it, the drywall should be fine over large temperature swings. If it's a detatched garage that you'll never heat, then don't bother. If it's an attached garage, then insulate as it's cheap and you'll benefit for decades.
Generally, insulation with an R-value between R-13 and R-21 is recommended. Adding insulation to exterior walls (including garage walls attached to living spaces) can help increase R-value and create a more powerful thermal boundary for your home. If you're insulating your garage ceiling, you'll need a higher R-value.
A continuous geomembrane or plastic liner behind the drywall protects the interior walls from any water damage. Because bathrooms and kitchens produce the most water vapor of any house or building, it has become standard practice to also use semigloss paint on the walls to act as a secondary vapor barrier as well.
Fire Resistant Door – According to the ICC, the garage entry door must be “equipped with solid wood doors not less than 1-3/8 inches (35 mm) in thickness, solid or honeycomb-core steel doors not less than 1-3/8 inches (35 mm) thick, or 20-minute fire-rated doors.”
Other openings between the garage and the residence shall be equipped with solid wood doors not less than 1-3/8” (35 mm) in thickness, solid- or honeycomb-core steel doors not less than 1-3/8” (35 mm) thick, or 20-minute fire-rated doors.
Any new build or home renovation that has three or more floors must have fire doors fitted to every habitable room that leads from a stairwell. This applies to loft conversions where an extra floor has been added to a two-storey home. Any door leading from your home into an integral garage must be a fire door.
Planning permission is not usually required to convert your garage into additional living space for your home, providing the work is internal and does not involve enlarging the building.
If you're going to drywall a garage by yourself the first thing that you'll need to do is buy your materials. You'll need drywall, of course. Drywall comes in sheets and it's a good idea to get extra sheets in case you measure wrong, a piece of drywall is damaged, or an accident happens.
For example, if you build without a permit in California, homeowners and contractors are liable, and both need to pay fines. According to California Contractors State License Board (CSLB), contractors must pay up to $5,000 per violation and are subject to disciplinary action.
