דמי האחסון כתובים בחוזה האחסון.

Here דמי means fees or charges for.

So:

• דמי האחסון = the storage fees

This word is very common in expressions like:

• דמי כניסה = entrance fee
• דמי משלוח = shipping charges
• דמי שכירות = rent

It is not the ordinary everyday word for money.

Because דמי is in a construct phrase.

In Hebrew, when two nouns are linked as X of Y, the first noun usually does not take ה. The definiteness comes from the second noun.

So:

• דמי האחסון = the storage fees
• literally: fees of the storage

Since האחסון is definite, the whole phrase is definite.

This is the same basic pattern as:

• ספר התלמיד = the student’s book
• מחיר המוצר = the price of the product

Because it agrees with דמי, which is grammatically treated as plural.

So Hebrew makes the predicate plural too:

• דמי האחסון כתובים = the storage fees are written

Compare:

• המחיר כתוב = the price is written
• העמלה כתובה = the fee/commission is written
• המחירים כתובים = the prices are written

So even if דמי feels like a fixed expression, it still triggers plural agreement.

In this sentence, כתובים is best understood as a passive participle functioning like an adjective: written.

Hebrew often uses this kind of form where English uses is/are + adjective/participle.

So:

• כתובים = written
• דמי האחסון כתובים = the storage fees are written

It describes a state, not an action happening right now.

Hebrew normally leaves out the present-tense form of to be.

So in the present tense:

• הוא עייף = he is tired
• הספר מוכן = the book is ready
• דמי האחסון כתובים = the storage fees are written

There is no separate word for is/are here. It is simply understood.

Because כתובים describes the result or state: the fees are already written down / listed / stated.

If you say נכתבים, that usually sounds more like:

• are being written
• get written

So:

• דמי האחסון כתובים בחוזה = the storage fees are written/stated in the contract
• דמי האחסון נכתבים בחוזה = the storage fees are being written in the contract / get written in the contract

For this sentence, כתובים is the natural choice.

בחוזה means in the contract.

It is made from:

• ב = in
• החוזה = the contract

When ב is attached to a definite noun with ה, the form contracts:

• ב + החוזה → בחוזה

So:

• בחוזה = in the contract

This happens very often in Hebrew with ב, ל, and כ.

Again, this is a construct phrase.

• חוזה האחסון = the storage contract
• literally: contract of the storage

In a construct phrase, the first noun usually does not take ה. The definiteness is shown on the second noun.

So:

• חוזה אחסון = a storage contract
• חוזה האחסון = the storage contract

That is why החוזה האחסון is not correct.

Because it belongs to two different noun phrases:

• דמי האחסון = the storage fees
• חוזה האחסון = the storage contract

Hebrew repeats it for clarity, just as English can repeat storage in:

• The storage fees are written in the storage contract

In real conversation, if the context is already clear, a speaker might shorten the second part to just בחוזה.

It can definitely mean more than just the literal idea of handwriting.

In a sentence like this, כתובים בחוזה often means:

• written
• listed
• stated
• specified

So a natural English translation could be:

• The storage fees are written in the storage contract
• The storage fees are listed in the storage contract
• The storage fees are stated in the storage contract

All of these capture the Hebrew well, depending on the tone you want.
