Do building codes require fire-rated attic ladders? As homeowners and jurisdictions become more aware of improving building safety, building codes and regulations continue to evolve. Increasingly, building codes are requiring the use of fire-rated ladders for attics to enhance occupant safety.
Buildings with combustible ceiling or roof construction shall have an attic access opening to attic areas that exceed 30 square feet (2.8m squared) and have a vertical height of 30 inches (762 mm) or more.
The rough-framed opening shall be not less than 22 inches by 30 inches (559 mm by 762 mm) and shall be located in a hallway or other location with ready access. Where located in a wall, the opening shall be not less than 22 inches wide by 30 inches high (559 mm wide by 762 mm high).
Many local building codes require the installation of fire-rated attic access doors in residential and commercial structures.
Fire rated loft hatches are typically required under building regulations for all houses with 3 or more storeys and blocks of flats.
Whilst not every property requires a fire rated loft hatch, they are imperative to protecting your people and your property. Once you have a clear understanding of the regulations you need to meet within your building, you can order your fire resistant loft hatch straight from our website.
All loft conversions need to have a protected escape route from the loft to the ground floor exit.

You will want an attic hatch that is about 2-4 inches thick.
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.
Attics containing appliances requiring access shall be provided with an opening and a clear and unobstructed passageway large enough to allow removal of the largest appliance, but not less than 30 inches (762 mm) high and 22 inches (559 mm) wide and not more than 20 feet (6096 mm) long when measured along the ...
The attic access opening can be in a clothes closet, a bathroom closet or “other readily accessible location” provided that the ac cess opening is not be less than 22 inches by 30 inches and has the required ceiling height above the opening.
You can find attic ladders made of aluminum, steel, or wood. Aluminum is generally the best all-around choice because it is lightweight and strong. Because aluminum is a rust-resistant metal, it's unlikely to be affected by humidity and temperature over the years.
To use them safely, ladder safety rules say you must: Not overload the ladder - only carry light equipment. Not over-reach - make sure the ladder is long enough. Follow the manufacturer's instructions on setup and use.
Most general contractors charge a labor fee of 10% to 20% of the total project cost. Depending on the complexity of your attic ladder installation, this amounts to anywhere from $100 to $500 for two to four hours of work.
3/4" is rated for 24" floor joists with live loads. Since this is storage/occasional usage, 1/2" plywood should work ok. If using OSB, definitely go with 3/4". My entire attic is floored in 3/4 OSB tongue and groove.
Attics whose joists have 16-inch centres can manage 1/2 plywood for attic floor. This is considering that not much weight will be placed on the floors. This is the choice for attics used solely for light storage.
23/32 inches is slightly less than 3/4 inches but more than 5/8 inches.
Timber ladders can start to weaken over time. If you're only going up and down once or twice a year the timber is fine, but the aluminium makes an attic space easier and more enjoyable to use more frequently.
When that single staircase is blocked in the event of a fire, the experience can be not only terrifying, but also deadly. For this reason, it is important to have an alternative means of escape from second and third story rooms. An emergency escape ladder stored near an accessible window creates a back-up escape route.
Attic ladders are available in different lengths, and you want the bottom of the “stringers” (ladder rails) to fully extend and touch the floor.
Moreover, houses built during or after the 1960s may have trussed roofs, which are characterised by their 'W' shaped frames that support both the roof and the floor. These trusses are not designed with loft conversion in mind, as altering them is a complex process that requires replacement with sturdier supports.
Fire doors
Fire-resistant doors are an essential feature when converting a loft into a habitable space in order to protect stairways and stop the spread of fire and smoke through escape routes. They need to provide fire protection for at least 20 minutes, therefore a 30 minute fire door (FD30) would be adequate.
Upper floor windows: On upper floors up to 4.5 meters from ground level, all habitable rooms (not kitchens or bathrooms) must be fitted with fire escape windows, unless the room has direct access to a protected stairway.
