Fire-Risk Assessment for Older Buildings

Older buildings carry fire risks that newer ones were designed out of, and short letting puts strangers inside them every week. The assessment is a document you produce, not a feeling you have.

Last updated: September 27, 2026

Ask a host whether their building is safe and you'll get a confident yes. Ask for the assessment that says so, and the conversation changes. A fire-risk assessment is a short document with a date on it, a name against it, and a list of what you found and what you did about it. Most older buildings don't have one, and the gap tends to surface at the worst moment.

Key Takeaways

• It's a document, not an opinion. Writing down the hazards, who's at risk and what you changed is the whole exercise.
• Some features you can only record. A single staircase or a wooden stair can't be rebuilt on a weekend; note it and mitigate what you can.
• Location decides placement. Alarms, escape signage and extinguishers belong where the local rules and the building's layout put them.
• Revisit when anything changes. A new let, a new room, building works or a guest report all reset the assessment.
• Named rules are examples. Every requirement below names a place and a date; check the current rules where the unit sits.

Why the assessment is a document rather than an opinion

A fire-risk assessment does five things, and all of them end up on paper. It identifies the hazards. It identifies who's at risk. It evaluates the risk and decides what to do about it. It records the findings. And it sets a date to review them. An assessment that exists only in your head fails at step four, which is the step an inspector or an insurer will ask about.

Short letting changes the calculation in ways a permanent resident's flat doesn't have to consider. Guests don't know the building. They sleep in a layout they've seen once, in the dark, in a building whose exits they've never used. They arrive with luggage, which is exactly what gets left in a hallway or in front of a door. Some of them won't read the signage in the language it's written in.

Where a rule already requires this, it's worth naming. In the United Kingdom, the Fire Safety Order 2005 is described as requiring a fire-risk assessment for short lets (industry source, in force). That's an example with a place and a date attached, not a universal rule — but it's the shape of the obligation in a lot of jurisdictions.

The practical point is smaller than the legal one. An assessment forces you to walk the building the way a guest will, at night, carrying a bag, looking for the way out. Most hosts have never done that. The document is how the walk gets remembered.

The building features you cannot change and must record

Older buildings have features that were acceptable when they were built and are the first things you'd fix if you could. A single staircase serving every floor. Internal doors that aren't fire-rated. Windows painted shut. Corridors narrower than a modern standard. A wooden stair, an old wiring run, a boiler in a cupboard off the hall. None of these are yours to rebuild, and the assessment isn't a plan to rebuild them.

It's a record. Write down what each feature is, where it is, who controls it and what you've done to reduce its effect. If the exit route is shared, the freeholder or the body corporate controls part of it, and your assessment should say so rather than claim a control you don't have.

Australia's New South Wales framework is a concrete example of what a short-let standard can ask for. Its short-term rental fire safety standard is described as requiring interconnected smoke alarms to AS 3786, plus evacuation signage and an information booklet. In multi-unit residential buildings it also calls for a keyless, inward-opening entry door, so a guest can get out without hunting for a key, plus a kitchen fire extinguisher and a fire blanket (official source, in force). Note what those items have in common: none of them requires rebuilding the building. They're all things you can fit.

Split your own list in two. What the building provides, which you record and report. What you provide, which you fit and maintain. Anything that falls between the two belongs to a conversation with whoever controls the shared parts.

Alarms, escapes and extinguishers, and where each belongs

Placement is where most home-made assessments go vague. "Smoke alarms fitted" tells a reader nothing about whether they'd wake someone up.

Work outward from where people sleep, then along the route they'd take to get out. Alarms go where sleeping occupants will hear them and where a fire is likely to start before it reaches them. Carbon monoxide alarms belong wherever there's a combustion appliance, and the timing of that requirement is set locally. Ontario's Fort Erie, for example, is described as requiring one carbon monoxide alarm per floor from 1 January 2026. It also requires at least one 2A:10B:C extinguisher per floor, with a monthly self-check record kept on file (official source, in force). Those are that place's numbers, not a standard to copy.

Extinguishers and blankets belong in the kitchen, which is where cooking fires start, and near any open flame or appliance that makes one likely. The NSW standard cited above puts a kitchen extinguisher and a fire blanket in multi-unit short lets, which is the same logic in a different jurisdiction.

Escape signage has to be readable by someone who has never been in the building, in the dark, possibly without their glasses. If a guest can't see the route, the route doesn't work. And the route itself has to stay clear: no bags, no drying racks, no spare furniture parked in the corridor, because that's what turns a passable exit into a blocked one.

Write the placement decisions down with the reason, not just the result. "Extinguisher by the kitchen door because the hob is the ignition source" is a line an inspector can follow. "Extinguisher fitted" isn't.

Guest-reported problems feed straight into this section. A chirping alarm, a broken light on the stairs, a door that won't close — those arrive as messages, and messages land in one place, because the inbox connects to Airbnb. What matters is that the report reaches the assessment rather than dying in a chat thread. Log it, fix it, note the date. That log is a lot easier to keep when the bookings the guest is staying on sit on one grid at localsbnb.com.

Revisiting the assessment when the building or the use changes

An assessment has a shelf life, and the things that shorten it are usually changes you made yourself. Adding a bed and raising the occupancy. Starting to let a basement room. Putting an electric vehicle charger in a shared garage. Each of those changes who's at risk and how they'd get out.

Changes you didn't make count too. Scaffolding on the building. New cladding. A lift taken out of service. A shared door propped open by a neighbour for the summer. The building isn't frozen, so the assessment can't be either.

The right interval is the one your local regime sets, so check it rather than assuming. What you can do without waiting for guidance is review on triggers. Review after any change to how the unit is let, any change to the building's structure or shared areas, any new appliance, and any incident or near miss reported by a guest. Then date the review and keep the earlier version.

When you do review, do it as a walk, not as an edit. Start at the front door, follow the exit route, and check each item on the old list against what's actually there now. Editing last year's document from a desk is how a dead alarm stays on a list for another year.

FAQ

Do I need a fire-risk assessment for one small unit?

Often yes, if the unit is in a building covered by a local fire safety regime, and the answer is set where the unit sits rather than by its size. Start by asking your local authority or fire service what applies to a short let in your building type, and keep the answer with the assessment.

I rent, so the building isn't mine. Whose assessment is it?

Renting doesn't remove the obligation that attaches to letting the unit. You can only record and mitigate what you control, and you should name what you don't and who does. Keep the two lists separate in the document so a reader can see exactly where your reach ends.

How often should I update it?

That's set by the regime you're under, and it isn't the same everywhere, so check rather than guess. In practice, review whenever the unit, the building or the way you let changes, and after any incident.

None of this needs a consultant or a template you buy. It needs a walk through the building at night, a two-page document, a date to review it, and the discipline to update it when something changes. Every rule named above is an example with a place and a date attached, and the rules where your unit sits are the ones that apply. If you'd rather keep the paper trail in one place, the bookings that fill the unit and the guest messages that flag a broken alarm both sit alongside the calendar at localsbnb.com.
