The Mamad: why the safe room has become essential
Ten years ago, a buyer coming from abroad would first look at the view, the kitchen, and the number of bedrooms. In 2026, one question comes before all others: "Is there a mamad ?" After a year marked by missile strikes, the safe room is no longer an Israeli technical detail: it has become a global purchasing criterion, closely examined by Jewish families in Paris, New York, London, Berlin, or Buenos Aires who are considering buying in Israel. Here's why, and what it actually costs.
What exactly is a mamad?
The mamad (merhav mugan dirati, "protected residential space") is a reinforced room built into the home, designed to protect its occupants from missile strikes, shrapnel, and, when properly sealed, chemical and biological threats. The law requires a door compliant with Israeli standard 4422 and an NBC filtration system compliant with standard 4570. Reinforced concrete walls, armored window, filtered ventilation: this is not just a storage closet, but a genuine in-home shelter, accessible within seconds without having to leave the apartment to reach an often-distant communal shelter.
The mamad has been mandatory in all new construction since the 1992 building law. As a result: the newer a building is, the more likely it is to be equipped. But the history of Israel's housing stock holds a major surprise.
More than one apartment in two does not have a mamad
This is the figure that changes everything for the foreign buyer: about 55% of apartments in Israel have no mamad at all. And the shortfall is concentrated precisely where the diaspora buys the most. According to market estimates, in Tel Aviv about 70% of homes lack one; in Jerusalem, 71%; in Haifa, 77%. These older cities, whose buildings largely predate 1992, are paradoxically the most exposed and the least equipped.
For a diaspora buyer, this means one thing: in the most sought-after neighborhoods, a charming apartment in a period building is very likely to have no safe room. The question is therefore not theoretical—it directly affects the family's safety during stays and the resale value of the property.
How much does a mamad cost in 2026?
Adding a mamad to a home that doesn't have one represents a significant investment. For a 12 m² room, 2026 Israeli market benchmarks put the cost between 100,000 and 120,000 shekels in a multi-unit building, and between 120,000 and 150,000 shekels in a single-family home, or roughly 33,000 to 49,000 USD at a rate of 3.05 NIS to 1 USD. Some sources mention up to 150,000 to 200,000 shekels for a full installation as part of major renovation work (reinforced concrete, blast-resistant door, armored window, air filtration), plus permit and engineering fees of 30,000 to 80,000 shekels.
This is not insignificant, but it must be weighed against the price of the properties in question: on an apartment worth several million shekels, the mamad represents just a few percentage points of the total price, in exchange for security and added value that are very real.
A mamad holds real resale value
Beyond safety, the mamad has become a financial asset. Properties equipped with one consistently sell for 10 to 15% more than comparable apartments without one. On an apartment worth 3 million shekels (nearly 984,000 USD), this represents a difference of 300,000 to 450,000 shekels, or roughly 98,000 to 148,000 USD. In other words, in many cases, the cost of installing a mamad is more than covered by the added value it generates.
This premium reflects a lasting shift in mindset. Since the recent episodes of regional tension, home safety has moved from being a bonus to being a non-negotiable criterion, for local buyers and the diaspora alike. A property without a mamad is now negotiated down; a property with a certified mamad sells faster. For buyers from abroad, who often occupy the home only a few weeks a year and rent it out the rest of the time, this premium is doubly strategic: it protects the family during stays and secures both resale value and rental income.
What diaspora buyers should check
Before signing, three checks are essential. Verify that a mamad exists and that it complies with standards 4422 and 4570, since an improvised "reinforced space" does not offer the same level of protection. If there is no mamad, assess the cost and feasibility of adding one, which depends on the building's structure and the agreement of the co-owners. Finally, factor this criterion into price negotiations: the absence of a mamad is a legitimate lever for lowering the offer.

A room that has become universal
In its own way, the mamad tells the modern story of Israel: a country that has built security into the very heart of its housing. For Jewish families around the world buying in Israel, this room is no longer a local curiosity but a given—a criterion that carries as much weight as location or square footage. Buying today means thinking about both asset value and peace of mind.
