Late Delivery in Construction Projects: Delay Damages, Loss of Rent and Current Judicial Practice

In real estate and construction law, particularly in land-for-flat agreements and pre-paid housing sales, late delivery remains the most entrenched source of dispute. Whether you are a company investing in a shopping centre development or an individual buying off-plan, a project that does not complete on the promised date causes real financial loss.

We look below at how delay damages, loss of rental income and non-pecuniary damages are calculated and claimed under the Turkish Code of Obligations.

The Legal Framework: Debtor's Default

Construction agreements are governed by the provisions on contracts for work (Articles 470-486 of the Code of Obligations).

Where the contractor fails to deliver the works in the agreed condition at the end of the agreed period, or of any permitted extension, the contractor falls into debtor's default (Articles 117 et seq.). A range of substantial claims then becomes available to the employer, whether landowner or purchaser.

Heads of Claim

1. Delay Damages (Liquidated Damages)

A well-drafted construction contract will include a delay penalty: a specified sum payable by the contractor for each day or month beyond the delivery date.

Ease of proof: Under Article 180/1, where the contract provides for a penalty, the employer may claim it without proving any loss at all.

The court's power of reduction, and the merchant exception: Under Article 182/3, a judge reduces of their own motion a penalty considered excessive. There is a decisive exception: under Article 22 of the Commercial Code, a debtor who is a merchant cannot ask for a penalty to be reduced on the ground that it is excessive. In construction contracts the contractor is usually a merchant, so the argument that the penalty is too high and will cause insolvency will not, as a rule, be heard. Conversely, where the landowner or purchaser is an individual and not a merchant, the court's power of reduction does apply to penalties imposed on them. Which way the penalty runs is therefore one of the most important points in the negotiation.

2. Loss of Rent (Positive Damage)

The most straightforward measure of actual loss from late delivery is rent. A purchaser who cannot take delivery on time and must rent elsewhere may claim the rent paid from the contractor.

Loss of rent arising from late delivery is treated as positive damage.

Calculation: The period between the contractual delivery date and actual handover is multiplied by the comparable market rent for the property, established through expert evidence, and claimed with interest. An argument that the property has appreciated in the meantime is not accepted as an answer.

3. Loss of Commercial Income (Investment Property)

Where the delayed property is a factory, office or retail unit, the investor may claim the income it would have generated or the rent it would have commanded.

The courts apply a strict standard here: the income must be certain and quantifiable, not speculative. A pre-lease protocol or a letter of intent with a prospective tenant should be produced.

4. Non-Pecuniary Damages

In off-plan sales in particular, years of uncertainty take a real toll on the purchaser. Where personality rights are affected, non-pecuniary damages may be claimed under Article 58 of the Code of Obligations.

One common error should be corrected here: non-pecuniary damages are not calculated as a percentage. They cannot be expressed as a proportion of the pecuniary loss. The judge assesses a lump sum, weighing the parties' financial circumstances, the degree of fault and the particular features of the case. In practice, awards in late delivery cases remain modest absent aggravating circumstances; the substantive heads of claim are the delay penalty and loss of rent.

Critical Mistakes at the Contract Stage

Recording delivery as "estimated":

A contractor may insert wording such as "the estimated delivery period is 18 months". Because "estimated" leaves the due date uncertain, default does not arise automatically.

What to do: The delivery date should be fixed and certain: "delivery on 15 July 2026". Where an estimate has been used, a notarised notice should be served promptly on expiry to place the contractor in default.

Occupancy permit or physical handover?

Where construction is complete and keys are handed over but the building permit of occupancy has not been obtained from the municipality (with the result that utilities may not be connected), this is not treated as delivery in law, and the delay penalty continues to run.

Erosion of a fixed penalty during high inflation (Article 180/2):

A contract from 2023 may provide for "TRY 10,000 for each month of delay", a figure now far below the real loss. Article 180/2 offers a route, but its direction is frequently misremembered in practice. The provision reads: "Where the loss suffered by the creditor exceeds the agreed penalty, the creditor may not claim the excess unless it proves that the debtor was at fault."

The burden therefore lies with the creditor, not the debtor. To recover more than the penalty you must establish two things together: that your loss exceeds the penalty, and that the contractor was at fault. This is the reverse of the presumption of fault in Article 112: the debtor does not escape by proving absence of fault; rather, the creditor who cannot prove fault fails.

The practical consequence is that a fixed-sum penalty operates, in an inflationary environment, much like a genuine cap. For long-term construction contracts it is therefore far more effective to draft the penalty on an indexed basis (to consumer or producer price indices, or to comparable rent) than to fight later over proof of both loss and fault.

Special Protection in Pre-Paid Housing Sales: The 48-Month Rule

For consumers buying off-plan, Consumer Protection Law No. 6502 provides protection beyond the general rules on contracts for work. This is the point most often overlooked in practice.

Under Article 44 of the Act, a pre-paid dwelling must be delivered within the period undertaken in the contract, and that period may not in any event exceed forty-eight months from the date of the contract. A longer period stated in the contract does not change that limit.

The same article also creates a delivery presumption: where the construction servitude is registered in the consumer's name in the land registry and possession is transferred, transfer and delivery are deemed to have taken place. That moment should be taken as the reference point when calculating delay.

Before commencing pre-paid housing sales, the seller must provide one of the securities required by the legislation, such as building completion insurance.

The consumer may exercise a right of withdrawal at any time before delivery without giving reasons, and the seller may not claim compensation beyond the limits set by the legislation.

Where the purchaser is a consumer, the dispute should be framed on these provisions together with the Code of Obligations, not on the latter alone.

The Contractor's Defences

A delayed contractor is not always in the wrong. Extensions of time and reductions in penalty may be justified where:

1. the employer failed to make interim payments on time;

2. force majeure intervened (pandemic, flood, earthquake);

3. delays in permitting or planning were attributable to the authorities.

This analysis is a general account for the construction sector and does not constitute legal advice on a specific matter.
