You are about to commit to living somewhere for a year, and there is one feature the photos never show and the agent rarely raises: where you and your family go when a siren goes off. In Israel that is not a remote worry, it is a routine part of where you live. Some flats let you reach safety in seconds without leaving the apartment. Others ask you to carry children down five flights and across a courtyard while a clock you cannot see is running. Those two flats can look identical online and rent for the same price. This page gives you a way to tell them apart with a number, so protection becomes something you check, not something you hope about.
What follows is a scoring tool. You gather three facts at the viewing, you read your area’s protection window, and you land on a score from 0 to 100. The score is not official and it is not personalized safety advice; the authoritative protection time and the nearest public shelter for any exact address come from the Home Front Command (Pikud HaOref) app and oref.org.il. What this page adds is a transparent way to compare flats before you sign, with every assumption shown so you can trust the result or adjust it.
The four kinds of protection, strongest to weakest
Every Israeli home falls back on one of four protected spaces, and the Home Front Command ranks them in a fixed order of preference. The higher up this list your flat reaches, the better it scores, because the higher options are both stronger and faster to get to.
- Mamad, the in-apartment safe room. A reinforced room inside your own apartment with thick concrete walls and ceiling, a heavy sealing steel blast door, a steel window shutter that locks from inside, and an air filter. You reach it in seconds without leaving home. Required in all residential construction permitted from 1992 onward.
- Mamak, the shared floor shelter. A reinforced space serving several apartments on the same floor. You leave your front door but stay on your level, so it is quick.
- Miklat, the building or public bomb shelter. A full shelter, usually in the basement or on the ground floor, serving the whole building. Israeli law has required these in apartment buildings since 1951. Reaching it means stairs and time.
- Stairwell or internal room. The last resort when there is no shelter you can reach in time. An interior space with as few outside walls, windows and openings as possible.
Two separate laws sit behind this. The 1951 Civil Defense Law is why older buildings have a basement miklat. The 1992 rule, which followed the missile strikes of the 1991 Gulf War, is why newer apartments have their own mamad. Knowing which law your building was built under tells you what to expect: a building permitted before 1992 very likely has no mamad, and your protection is the shared or public shelter plus the stopwatch.
The number that actually decides it: time versus the window
Here is the heart of the tool. For any shelter outside your apartment, protection is a race. On one side is the time it takes your household to get inside the shelter. On the other is the protection time, the fixed number of seconds the Home Front Command gives your area between the siren and impact. If your time to reach the shelter is comfortably under the window, the flat is protected. If it is not, the flat is under-protected no matter how nice it is.
The protection windows are set per location and do not change with the flat. These are official Home Front Command values:
| Where the flat is | Protection window after the siren |
|---|---|
| Gaza-border towns: Sderot, Netivot, Ashkelon | About 15 seconds |
| Lebanon-border towns (for example Nahariya) | About 15 seconds |
| Safed | About 30 seconds |
| Haifa, Tiberias | About 1 minute (60 seconds) |
| Most of the country, including Tel Aviv and Gush Dan | 1.5 minutes (90 seconds) |
| Farthest areas | Up to 3 minutes (180 seconds) |
After you are inside, the rule everywhere is the same: stay in the protected space for 10 minutes after the alert. Northern and border windows shift with the security situation, so for the flat you are actually considering, pull the live value for that exact address in the Pikud HaOref app rather than trusting a town-level figure.
One important thing the siren does not always tell you
There are really two kinds of warning, and they give you very different amounts of time. Long-range ballistic missiles fired from far away can trigger an early national warning roughly 15 to 30 minutes before impact, which is time to gather everyone and move calmly. Short-range rockets give you only the fixed per-area window above, 15 seconds to 3 minutes. This tool is built on the short window, the worst case, because a flat that is safe under 90 seconds is safe under 15 minutes too, but not the other way around. Build for the hard case and the easy case takes care of itself.
Figure A: how long it really takes to reach each kind of shelter
An in-apartment mamad wins everywhere because it costs you only seconds; a building or public shelter can quietly fail the window once you add floors and distance. To show this in numbers I built a simple, transparent model of the time it takes a household to get into a shelter, then compared it to each protection window. Nothing here is an official measurement; it is arithmetic from stated, sourced assumptions, so you can change any input and redo it yourself.
The model. Time to shelter equals the time to gather your family (assume about 10 to 15 seconds with children) plus the walking distance divided by walking speed plus the stairs. Walking speed for a normal adult is 1.4 meters per second (about 5 km/h); with small children or an elderly person, use 0.8 to 1.0 meters per second. Descending stairs under load is taken at about 20 seconds per floor, a deliberately conservative figure (real building evacuations have run close to a minute per floor, while a single unobstructed person can do 10 to 15 seconds). Every number is stated so you can argue with it.
| Shelter situation | Time to get inside (this model) | Passes 15s border? | Passes 90s Tel Aviv? |
|---|---|---|---|
| In-apartment mamad, any floor | About 5 to 20 seconds (a few steps + door) | Tight but yes | Yes, easily |
| Mamak on the same floor | About 15 to 30 seconds | No | Yes |
| Building miklat, 2nd floor (gather 15s + 2 floors x 20s) | About 55 seconds | No | Yes |
| Building miklat, 5th floor (gather 15s + 5 floors x 20s) | About 115 seconds | No | No, it fails |
| Public miklat 50 m away, ground floor (gather 15s + 50/1.4) | About 51 seconds | No | Yes |
| Public miklat 100 m away, ground floor (gather 15s + 100/1.4) | About 86 seconds | No | Just barely |
What the numbers say. An in-apartment mamad clears the 90 second Tel Aviv window with more than a minute to spare and is the only option that even approaches the 15 second border window. A fifth-floor flat that relies on a basement shelter needs about 115 seconds on this model, so it fails the 90 second window before you even count the walk to the stairwell, which matches the well-known warning that a high floor plus a basement-only shelter is a problem. A public shelter is fine when it is close and you are low down, and marginal once it is 100 meters off. In a 15 second border zone, only a safe room or a stairwell a few steps away truly fits, which is exactly why those towns are built around in-apartment and same-floor protection.
Basis: protection windows are Home Front Command values (immediate / 15s / 30s / 45s / 60s / 90s / up to 180s; Tel Aviv 90s; Sderot, Netivot, Ashkelon about 15s). Walking speed 1.4 m/s is the standard adult preferred walking speed; 20 seconds per floor is a conservative descent-under-load assumption drawn from stairwell-evacuation research. Gather time of 15 seconds is an assumption for a family with children. These are engineering estimates for comparison, not a guarantee for any real building.
Figure B: scoring a unit out of 100
Score the flat by starting from the shelter type, then adjust for whether you can actually reach it in time. This is the tool to carry to a viewing. It combines the three things that matter, in the order they matter: what kind of shelter the flat has, how the floor and distance affect your time to reach it, and how tight your area’s window is. The weights are this page’s own scheme, not an official rating, and the logic is shown so you can trust or adjust it.
Step 1, the base score from shelter type. This reflects the Home Front Command priority order and the strength of each space.
| What the flat has | Base score |
|---|---|
| Working in-apartment mamad (post-1992, sealing door + filter) | 85 |
| Mamak (reinforced shelter on your own floor) | 70 |
| Building miklat (basement or ground-floor shelter) | 55 |
| Public miklat only (no shelter in your own building) | 40 |
| Stairwell or internal room only, no real shelter | 20 |
Step 2, the time-margin adjustment. Work out your time to shelter from Figure A, then subtract it from your area’s protection window. That gap is your margin.
- In-apartment mamad: ignore this step, you reach it in seconds. Keep the base 85.
- Margin of 30 seconds or more (you reach the shelter with time to spare): add 10.
- Margin of 0 to 30 seconds (you just make it): no change.
- Margin below 0 (you cannot reach it in time): subtract 30. The flat is under-protected; the stairwell is your real fallback.
Step 3, the mamad quality and access checks (apply if relevant). A safe room that is broken or blocked is not a safe room.
- Mamad used as a storage closet, packed so you cannot get in fast: subtract 15.
- Sealing blast door, steel shutter or air filter damaged or missing: subtract 10.
- Mamad smaller than the 9 square meter minimum (older special-approval rooms can be 5): subtract 5.
- Building miklat kept locked with no clear plan for who holds the key, or used for storage that blocks entry: subtract 15.
- Public-shelter route crosses a busy road or is poorly lit: subtract 5.
Reading the result. 80 to 100: strong protection, sign with confidence. 50 to 79: workable, but fix the access issues (clear the room, sort the key) and know your route. Under 50: treat protection as a genuine reason to keep looking, and never accept this band quietly if you have young children, an elderly parent, or anyone who cannot move fast.
Worked example. A fifth-floor flat in Tel Aviv with no mamad, relying on a basement miklat. Base score 55. Time to shelter from Figure A is about 115 seconds against a 90 second window, so the margin is negative and you subtract 30, landing at 25. If the shelter is also kept locked with no key plan, subtract 15 more, down to 10. The same flat on the ground floor with the shelter just down the hall would have a margin near 75 seconds, adding 10 to reach 65. Same building, same rent, a 55 point swing in protection driven entirely by floor and access.
Basis: the base scores follow the Home Front Command shelter priority order (mamad > mamak > miklat > stairwell). The mamad quality gates use the published standards (minimum 9 square meters; IS 4422 sealing blast door; IS 4570 air filtration; barless emergency-exit window). The time-margin step uses Figure A. The weights are a decision aid, not an official protection rating.
What to actually check at the viewing
Walk the flat with this list and you will have everything the score needs.
- Is there a mamad inside the apartment? Look for one room with a noticeably heavy steel door that seals, a thick steel window shutter that closes and locks from inside, and an air filter unit. That is the safe room. Ask to open and close the door and the shutter; they should move freely.
- If no mamad, what is the fallback? A mamak on your floor, a basement or ground-floor miklat, or only a public shelter down the street. Ask the landlord directly and ask to see it.
- Walk the route and time it. From the flat’s front door to inside the shelter, walk it once at a normal pace and count the seconds. That single number, against your area’s window, settles most of the score.
- Check the shelter is usable, not a junk room. A building miklat crammed with bikes, boxes and old furniture cannot protect you. Clearing and preparing it is the building committee’s job, so ask who manages it.
- Find the key. Legally, access to a building shelter must be immediate. In practice a locked miklat with no clear key holder is a failure. Ask exactly how every resident gets in within seconds.
- Confirm everyone can get there. Picture the slowest member of your household doing the route alone. If a child or an older adult cannot make it in time, the flat does not work for your family even if it would for a single fast adult.
If you are scoring the rest of the apartment at the same time, the broader walk-through, including damp, AC and the meters, lives in the apartment viewing checklist; this page owns only the protection side.
How to find the nearest public shelter for an address
When a flat has no mamad and no building shelter, a public miklat is your fallback, so you need to know where it is before you sign, not during a siren. Several official and practical tools show you:
- The Pikud HaOref (Home Front Command) app, the official source, on Android and iOS. It gives your exact protection time and alerts for your location.
- oref.org.il, the Home Front Command website, with a defense-zones map.
- Safeway, a GPS app that points you to the nearest shelter.
- Your municipality’s shelter map or PDF, often on the city website.
- A quick search for shelters near the address in your maps app, as a rough cross-check.
Open the app while you are standing in the flat. If the nearest public shelter is farther than you can walk in your area’s window, you have your answer about that flat.
If there is no shelter you can reach in time
Plenty of older buildings leave you with the stairwell as the real fallback, so know how to use it. The Home Front Command guidance for when you have no mamad or reachable shelter: go to an interior room with as few outside walls, windows and openings as possible, and shut the door. Avoid bathrooms and kitchens full of ceramics and glass, which shatter. Never use the elevator. In the stairwell, the protected part is the flights of each floor except the top two stories and the ground floor: from the top floor of a building of three or more stories, go down two flights; in a three-story building, go down one, to the middle. Pick your spot in advance and make sure everyone in the home knows it.
The short words you need
- Mamad: the reinforced safe room built inside an apartment, your fastest and strongest protection.
- Mamak: a reinforced shelter shared by the apartments on one floor.
- Miklat: a full bomb shelter for a building or the public, usually in a basement or on the ground floor.
- Protection time (zman hitgonenut): the seconds your area gets between the siren and impact, set per address by the Home Front Command.
- Vaad bayit: the building committee, responsible for clearing and preparing the shared shelter.
Before you decide, run this check
Did you find the protected space and confirm what type it is, time the walk to it from the front door, look up the area’s protection window in the app, picture the slowest person in your household making the trip, and confirm a building shelter is unlocked and clear rather than a storage room? If any of those is missing, you have a guess, not a score. Do not commit yet.
Questions renters ask about safe rooms and shelters
The flat has no mamad. Should I refuse it?
Not automatically, because many buildings from before 1992 have none and people live in them safely by relying on a shared or public shelter. The real test is whether you can reach a protected space within your area’s window. If you can, with margin, the flat can score in the workable band. If you cannot, treat it as a reason to keep looking.
Who is responsible for keeping the building shelter usable?
The building committee (vaad bayit). Clearing storage, preparing the miklat and managing access are its job. If the shelter is a junk room, that is a question for the landlord and the committee before you sign, not after. The committee’s role and fees are covered on the vaad bayit page.
Can the landlord lock the building shelter?
Access is meant to be immediate, so a locked shelter with no clear way for every resident to get in within seconds is a genuine fault. Ask exactly how you would enter during an alert, and who holds the key.
Does a high floor make a flat less safe?
Only when the flat relies on a shelter below you. With an in-apartment mamad, the floor barely matters, since you reach it in seconds. Without one, every floor adds roughly 20 seconds of stairs on this page’s model, which is how a fifth-floor flat with a basement-only shelter can fail a 90 second window.
What if I cannot reach the shelter in time during an actual siren?
Use the stairwell rule and an interior room with the fewest outside walls and windows, away from the elevator. That is the official fallback, and it is exactly why a flat that forces you into it should score lower in your decision.
Where do I get the real protection time for my exact address?
The Pikud HaOref (Home Front Command) app and oref.org.il. The town-level figures here are for comparison; the app gives the live, address-specific value, which can change with the security situation, especially in the north.
Is the safe room mine to use as a normal room?
Yes, day to day it is just a room and many people use it as a bedroom or office. The point is that it must stay usable, meaning the door and shutter still work and it is not so packed with belongings that you cannot get in fast.

Your next step
At your next viewing, find the protected space, time the walk to it from the front door, look up the address window in the Pikud HaOref app, and run the flat through the three-step score above. A flat that lands at 80 or more is protected; anything under 50 should weigh heavily against signing. When you have scored protection, finish the rest of the unit with the apartment viewing checklist, line up your papers in the documents you need to rent, and read the broader process on the renting in Israel hub and in how to rent in Israel before you sign. If a war or emergency later forces you out of the home, your lease rights are covered in war and evacuation lease rights.
