Choosing a Home Safe: Fire Rating, Cash Rating and Where to Bolt It

Most people buy a safe based on size and price, then wonder later why it didn't survive a house fire or why their insurer won't cover what's inside it. The two numbers that actually matter are the fire rating and the cash rating, and neither one is what most people assume. Get those two right first, then worry about where to bolt it down.

What does a fire rating on a safe actually mean?

A fire rating tells you how long the inside of the safe stays below the temperature at which paper and most documents start to char, which is around 350°F (177°C). A safe rated "350-1 hour" (UL or ETL tested) keeps interior temperatures under that mark for 60 minutes in a standard test fire. A "350-2 hour" safe does the same for two hours.

That rating is for paper and documents. It is not the same as a media rating for USB drives, hard drives or photos, which need to stay much cooler (around 125°F/52°C) or they're ruined even if the paper inside survives fine. If you're storing a laptop backup or old family photos, check for a separate media-rated interior or a fireproof media box inside the safe, not just the document fire rating on the box.

• Budget document safes (SentrySafe, First Alert). Usually 30 minute to 1 hour rating, fine for insurance papers, passports, a will.
• Mid-range home safes (Gardall, Phoenix, Cannon). 1 to 2 hour fire rating, better for houses with wood framing where a fire can burn longer before firefighters reach the room.
• Commercial grade (AMSEC, Chubb). 2 hour-plus ratings, usually heavier gauge steel too, which helps with burglary resistance as a side benefit.

What is a cash rating and why does it matter more than the fire rating for insurance?

Cash rating (sometimes called a cash/contents rating) is a number insurers use to decide how much value they'll cover inside that specific safe, based on how hard it is to break into, not how fireproof it is. A safe might have a great fire rating and a weak cash rating, or the reverse. Most home insurance policies in BC cap cash and jewellery coverage in an unrated safe at a few thousand dollars, no matter how solid the box looks.

If you're storing more than paperwork, cash, jewellery, firearms documentation or a decent watch collection, call your insurer before you buy. Ask them directly: "what cash rating do I need for X dollars of coverage?" Typical home safes top out around a $10,000 to $35,000 cash rating. Anything beyond that usually means a commercial-grade TL-15 or TL-30 rated safe, which is a different size and budget entirely, often $2,000 to $6,000 for the unit alone.

Floor, wall or closet: where should the safe actually go?

Where you bolt a safe matters almost as much as the safe itself. An unbolted safe under 200 lbs can simply be carried out by two people, rating or no rating. North Vancouver's housing stock splits roughly into older wood-frame homes with crawl spaces or basements, and newer condos and townhomes on concrete slabs, and that split actually changes your best option.

• Concrete basement floor. Best option if you have one. Bolting into concrete with 3/8" or 1/2" expansion anchors gives a solid, low-profile install that's hard to pry and doesn't need wall framing.
• Closet floor on a wood subfloor. Workable, but you need to bolt through the subfloor into a joist, not just into plywood. Check joist direction first or the bolts pull straight out under force.
• Interior wall mount. Only for small document safes. Exterior walls in coastal BC see more moisture and temperature swings, which isn't ideal for anything storing electronics or photos long term.
• Avoid garages and crawl spaces. Humidity off the water table and poor insulation cause rust on hinges and bolts faster than anywhere else in the house.

Given Metro Vancouver's seismic risk, a safe bolted to concrete is also simply more stable in an earthquake than one resting loose on a shelf or closet floor, where it can tip or shift.

How big a safe do you actually need?

Buy for what you'll store in five years, not what you have today. A safe that's too small gets left open "just for a minute" to fit something awkward in, which defeats the point entirely. A letter-size document safe (roughly 1 cubic foot) suits passports and a will. Anything with jewellery, firearms, or a few months of paperwork usually needs 1.5 to 2.5 cubic feet.

Getting it installed properly

A locksmith can bolt most home safes in under an hour once the location is picked, with labour typically running $100 to $250 depending on floor type and whether we're drilling concrete or framing. We'll also check the bolt pattern matches what's underneath before committing to anchors, since a mismatch means redrilling. If you're not sure the safe you're eyeing has a legitimate cash rating or a real fire rating versus marketing language on the box, send us the model number before you buy and we'll tell you straight what it's actually rated for.

Frequently asked questions

Can any safe be bolted to a concrete floor?

Most safes under about 750 lbs come pre-drilled for floor bolting, but check the base plate before buying if bolting is non-negotiable for you. Heavier commercial units sometimes rely on sheer weight instead.

Does a higher fire rating always mean a better safe overall?

Not necessarily. Fire rating and cash rating are tested separately, so a safe can be excellent against fire and weak against a crowbar, or the other way round. Check both numbers, not just one.

How long does safe installation usually take?

Bolting a standard home safe to concrete or a joist usually takes under an hour once the spot is chosen. Drilling through tile or adding anchors in awkward spots can push that closer to two hours.
