Türkiye's mandatory earthquake insurance system, known as DASK (Doğal Afet Sigortaları Kurumu), is one of the more distinctive features of the country's property market for foreign buyers to understand before closing on any residential asset. For Turkmenistan-based investors weighing acquisitions in Türkiye, DASK is not an optional add-on. It is a legal precondition for registering title and a practical determinant of long-term holding costs.
What DASK Actually Covers
DASK is a state-backed insurance pool established after the 1999 Marmara earthquake to spread catastrophic risk across the national housing stock. It covers physical damage to the structure of a residential building caused by earthquake and related perils such as fire, explosion, tsunami, or landslide triggered by seismic activity. It does not cover contents, furniture, vehicles, or bodily injury, and it excludes purely decorative elements and outbuildings. Coverage limits are set annually by regulation and are generally modest relative to the replacement cost of higher-value properties, which is why many investors in premium segments pair DASK with a supplementary private earthquake or all-risk policy.
Key point : DASK is mandatory for any property to be registered at the Land Registry (Tapu) and for most mortgage-backed transactions. Without a valid DASK policy number, a title transfer can be delayed or rejected outright.
Why This Matters More for Foreign Buyers
Investors coming from Turkmenistan, where seismic risk pricing and mandatory catastrophe insurance are not standard features of the property market, sometimes treat DASK as a minor administrative fee. In practice it should be read as a signal. The premium a given building attracts is a function of construction year, structural system, seismic zone, and building height, all of which are the same variables that determine physical vulnerability and resale liquidity after Türkiye's post-2018 zoning and building code reforms. A property in a coastal or Marmara-region seismic zone with an outdated structural report will carry a materially different DASK premium than a comparable unit in a newer, code-compliant building, even within the same district.
Buyers should request the DASK premium quote as part of technical due diligence, not after the purchase agreement is signed. A disproportionately low premium relative to a building's age can be a red flag that the declared building data is inaccurate or that a required structural assessment has not been filed.
Practical Steps for Structuring the Purchase
Verify building age and structural class : DASK premiums are tiered by construction year and risk zone. Ask the seller or developer for the building's risk group classification before agreeing on price.
Confirm the policy transfers cleanly at closing : DASK policies are typically renewed annually and tied to the specific unit, not the owner. At transfer, a new policy should be issued in the buyer's name concurrently with Tapu registration to avoid a coverage gap.
Consider supplementary coverage for higher-value units : Because DASK payout caps are set at a national baseline, investors acquiring larger residences or commercial-residential mixed units in Ashgabat-linked investor circles active in Istanbul, Antalya, or the Aegean coast often layer a private catastrophe policy on top to reach full replacement value.
Factor DASK renewal into holding cost models : For investors running properties as rental assets, the annual DASK premium, together with building management fees, should be included in net yield calculations from the outset rather than treated as a rounding error.
A Regulatory Environment in Motion
Türkiye's building and insurance regulators have continued to tighten enforcement of both DASK compliance and structural safety certification following recent seismic events in the region. Investors should expect periodic increases in premium bands for older building stock and continued scrutiny of self-declared structural data at the point of sale. Working with an advisory team that can independently verify a building's seismic risk classification, rather than relying solely on seller disclosures, remains the most reliable way to avoid post-purchase surprises.
For Turkmenistan investors building a Turkish property allocation, DASK compliance should be treated as a standard line item in every acquisition checklist: confirmed before offer, verified before closing, and budgeted for the life of the holding.
