For pendlerstatus kreves en husleiekontrakt.

Here for means something like for the purpose of, regarding, or in order to get.

So For pendlerstatus means for commuter status or more naturally in English, to qualify for commuter status.

This use of for is common in official or administrative Norwegian:

• For opptak kreves dokumentasjon. = For admission, documentation is required.
• For medlemskap må du betale. = For membership, you must pay.

Norwegian often leaves out the article with abstract nouns or status/category words, especially in formal language.

So for pendlerstatus does not mean that the article has been forgotten. It is a normal way to say for commuter status.

If you added a definite article, it would usually sound more specific:

• for pendlerstatus = for commuter status in general
• for den pendlerstatusen = for that particular commuter status

In this sentence, the general meaning is intended, so no article is needed.

It is a compound noun, which is extremely common in Norwegian.

It is made up of:

• pendler = commuter
• status = status

Together, pendlerstatus means commuter status.

Norwegian very often combines nouns into one word where English would use two separate words:

• husleiekontrakt = rental contract / lease agreement
• skattekort = tax card
• arbeidskontrakt = work contract

So a learner should get used to reading long compound nouns as one unit.

Kreves is the passive form of kreve.

• å kreve = to require / to demand
• krever = requires / demands
• kreves = is required

So:

• Loven krever dokumentasjon. = The law requires documentation.
  This is active.
• Dokumentasjon kreves. = Documentation is required.
  This is passive.

In your sentence, kreves means is required:

• For pendlerstatus kreves en husleiekontrakt.
• For commuter status, a lease agreement is required.

This is because Norwegian normally follows the V2 rule in main clauses: the finite verb usually comes in the second position.

Here the first element is the prepositional phrase:

• For pendlerstatus = first element

So the finite verb comes next:

• kreves = second element

Then comes the noun phrase:

• en husleiekontrakt

That gives:

• For pendlerstatus kreves en husleiekontrakt.

This word order is especially common in formal, written, or bureaucratic Norwegian.

You could also say:

• En husleiekontrakt kreves for pendlerstatus.

That is grammatically possible, but it sounds less natural in this official style.

Yes, in terms of meaning, en husleiekontrakt is what is required, so it functions as the logical subject of the passive sentence.

However, because of Norwegian word order, it comes after the verb here.

This can feel unusual to English speakers, because English often prefers:

• A lease agreement is required for commuter status.

Norwegian allows the sentence to begin with the prepositional phrase and still keep the verb in second position:

• For pendlerstatus kreves en husleiekontrakt.

So even though en husleiekontrakt comes later, it is still the thing being required.

The indefinite form is used because the sentence means a lease agreement is required, not the lease agreement is required.

That is, it refers to any qualifying rental contract, not one specific contract already known to both speaker and listener.

Compare:

• en husleiekontrakt = a lease agreement
• husleiekontrakten = the lease agreement

In administrative language, the indefinite form is very common when talking about required documents:

• Pass kreves. = A passport is required.
• En underskrift kreves. = A signature is required.

It is another compound noun:

• husleie = rent
• kontrakt = contract

So husleiekontrakt literally means rent contract, and in natural English it is usually rental contract or lease agreement.

A very similar Norwegian word is leiekontrakt, which is also commonly used. In many contexts, they mean almost the same thing.

Yes. That is a very common alternative.

• Det kreves en husleiekontrakt. = A lease agreement is required.
• For pendlerstatus kreves en husleiekontrakt. = For commuter status, a lease agreement is required.

The version without det is more compressed and formal. This is especially common in official notices, rules, and bureaucratic writing.

So the sentence in your example sounds quite formal and administrative.

It is grammatical and natural, but it sounds formal and a bit bureaucratic.

In everyday speech, people might say something more direct, for example:

• Du må ha en husleiekontrakt for å få pendlerstatus.
• You need a lease agreement to get commuter status.

So the original sentence is the kind of wording you might see in:

• official websites
• tax information
• application instructions
• legal or administrative documents

Yes, absolutely. It is a complete sentence.

It contains:

• a prepositional phrase: For pendlerstatus
• a finite verb: kreves
• a noun phrase: en husleiekontrakt

Norwegian official style often uses short, dense sentences like this. They may feel a little stripped-down compared with everyday spoken language, but they are still complete and correct.
