Swedish investors evaluating real estate or construction projects in Türkiye often focus their due diligence on price, permits, and contractor selection, and treat insurance as an administrative afterthought to be arranged once a purchase closes. This ordering is backward. Türkiye's insurance and risk framework is a regulatory system in its own right, with mandatory products, coverage gaps, and documentation requirements that materially affect both acquisition timing and long-term asset protection. For a Swedish buyer accustomed to a mature, standardized Nordic insurance market, the Turkish system rewards early attention and penalizes assumptions carried over from home.
The mandatory baseline: DASK
Every residential property transaction and every building permit renewal in Türkiye requires proof of a valid Zorunlu Deprem Sigortasi (DASK), the compulsory earthquake insurance policy administered under state oversight. DASK is not optional and not negotiable: without a current policy, title transfer at the land registry (tapu) can be refused, and utility connections can be withheld. The coverage itself is capped and calculated per square meter of the building's construction class, meaning DASK alone rarely covers full reconstruction cost on a mid-to-high-value property. Swedish buyers should treat DASK as the regulatory floor, not the risk management ceiling.
Practical point : DASK premiums are recalculated annually and tied to building age, construction type, and seismic zone. A structure completed under the post-2018 TBDY seismic code will typically price more favorably than an older building in the same district, which is one more reason construction-vintage due diligence and insurance due diligence should happen together, not sequentially.
Where DASK stops: supplemental coverage
Because DASK caps payouts well below replacement value for larger or higher-specification properties, most institutional-grade transactions in Turkish layer supplemental all-risk or comprehensive building insurance (konut sigortasi or ticari paket policies for commercial assets) on top of the mandatory policy. These supplemental products cover fire, flood, theft, third-party liability, and business interruption in ways DASK does not touch at all. For a Swedish investor used to comprehensive homeowner or commercial policies as the norm, the two-tier structure, mandatory earthquake cover plus voluntary comprehensive cover, is the single most important structural difference to internalize before budgeting.
Construction-phase insurance and contractor obligations
For development and renovation projects, a separate layer applies during the build itself. Contractor All Risk (CAR) insurance is standard practice on any serious construction contract in Türkiye, covering physical loss to the works, third-party liability on site, and often extending to professional indemnity for the design team. Swedish investors should confirm CAR coverage is written into the construction contract as a named obligation, not left to informal assurance, and should request the policy certificate and confirmation of premium payment before mobilization, since a lapsed or unpaid CAR policy leaves the owner exposed for the full construction period.
Insurable value and currency exposure
A subtler regulatory point: Turkish insurance policies are typically denominated and settled in Turkish lira, even when the underlying asset was purchased in foreign currency. In a period of lira volatility, this creates a mismatch between the euro or dollar value of the asset and the lira-denominated payout in a claim scenario. Swedish investors should ask insurers directly how insurable value is recalculated at renewal and whether indexation clauses exist, rather than assuming the sum insured tracks the asset's foreign-currency value automatically.
Documentation and claims practicalities
Turkish insurers generally require the building's yapi kullanma izin belgesi (occupancy permit) and, for post-2019 construction, evidence of yapi denetim (independent construction supervision) sign-off to issue or honor certain policies without exclusions. Missing or informally obtained permits are a common reason claims are contested after the fact, not before the policy is issued. This makes permit and supervision documentation part of insurance due diligence, not a separate workstream.
A regulatory environment, not a paperwork step
For Swedish investors, the practical takeaway is to sequence insurance review alongside legal and structural due diligence, not after closing. Confirming DASK status, assessing whether supplemental coverage is warranted given the asset's value and use, verifying CAR obligations on any construction contract, and understanding currency treatment of the sum insured should all be resolved before funds are committed. Advisory support familiar with both the regulatory requirements and the practical claims environment in Türkiye can materially reduce the chance of a coverage gap surfacing only when it matters most.
