Utflyttingen krever flyttevask og bærehjelp.

Because -en is the definite ending for many masculine nouns in Norwegian.

• en utflytting = a move-out / a moving out
• utflyttingen = the move-out / the moving-out process

In this sentence, utflyttingen refers to a specific move-out situation, not just move-outs in general.

Also, utflytting is a verbal noun built from the verb å flytte ut (to move out).

Yes. This is normal Norwegian main-clause word order:

Subject + verb + rest

So:

• Utflyttingen = subject
• krever = verb
• flyttevask og bærehjelp = what is required

This is the most neutral, standard order in a statement.

If you move something else to the front, Norwegian still keeps the finite verb in second position:

• Ved utflytting kreves flyttevask og bærehjelp.
• I forbindelse med utflyttingen krever man ofte flyttevask og bærehjelp.

That verb-second pattern is very important in Norwegian.

Krever is the active form: requires.

So the sentence literally has the structure:

• The move-out requires move-out cleaning and carrying help.

You could also use a passive-style wording in Norwegian, for example:

• Ved utflytting kreves flyttevask og bærehjelp. = When moving out, move-out cleaning and carrying help are required.

Both are possible, but utflyttingen krever ... is an active construction with utflyttingen as the subject.

It is the present tense of the verb å kreve (to require, to demand).

Forms:

• å kreve = infinitive
• krever = present tense
• krevde = past tense
• har krevd = past participle/perfect form

In Norwegian, the present tense often ends in -r, so krever is a very typical present-tense form.

Because Norwegian very often forms compound nouns as a single written word.

So:

• flytte + vask → flyttevask
• bære + hjelp → bærehjelp

This is extremely common in Norwegian. English often writes these as two words or with a more flexible structure, but Norwegian usually prefers one compound word.

A few more examples of the same pattern:

• bil + dør → bildør
• sommer + ferie → sommerferie
• hus + nøkkel → husnøkkel

For learners, this is one of the biggest spelling differences between English and Norwegian.

Flyttevask is a compound noun:

• flytte relates to moving house
• vask means cleaning / wash

So flyttevask means the thorough cleaning that is expected when someone moves out of a home.

It is a fixed, very common practical word in Norwegian, especially in housing and rental contexts.

Related words:

• å vaske = to clean / wash
• vask = cleaning / wash
• flytting = moving
• utflytting = moving out

Bærehjelp is also a compound noun.

It comes from:

• å bære = to carry
• hjelp = help

So bærehjelp means help with carrying things, for example furniture, boxes, or heavy items during a move.

Notice that the first part changes shape:

• verb: å bære
• compound form: bære-
• noun: bærehjelp

That is normal in compounds: the verb stem or verb-related form is used as the first element.

Because in Norwegian, after a verb like krever, nouns often appear without an article when you mean them in a general or functional sense.

So:

• krever flyttevask og bærehjelp = requires move-out cleaning and carrying help

This sounds natural because it is talking about required services/things in general, not one specific cleaning job and one specific helper.

You could add articles in other contexts, but this sentence is most natural without them.

Compare:

• Utflyttingen krever flyttevask.
• Utflyttingen krever en grundig flyttevask.

The second sentence uses en because it specifies a thorough move-out cleaning.

Yes. Og simply means and and joins two noun phrases of the same type:

• flyttevask
• bærehjelp

Together they function as what is required by utflyttingen.

So the structure is:

• Utflyttingen = subject
• krever = verb
• flyttevask og bærehjelp = coordinated object/list

This is very straightforward grammatically.

Yes, but it changes the feel of the sentence.

• Utflyttingen krever flyttevask og bærehjelp. = talking about the move-out, a specific move-out situation

• Utflytting krever flyttevask og bærehjelp. = more general, like moving out requires move-out cleaning and carrying help

So both are possible, but:

• utflyttingen = specific event/situation
• utflytting = the activity in general

It is understandable and fairly natural, but it has a practical, somewhat formal or informational tone.

It sounds like something you might see in:

• a checklist
• a moving-company ad
• a housing notice
• practical information for tenants

In casual speech, people might also say things like:

• Når man flytter ut, må man ofte ha flyttevask og bærehjelp.
• Ved utflytting trenger man flyttevask og bærehjelp.

So the original sentence is fine, but it sounds more like written information than everyday conversation.

The parts English speakers often find tricky are:

• utflyttingen
• flyttevask
• bærehjelp

A few useful pronunciation notes:

• y in flytte- is a front rounded vowel, not like English y in my
• æ in bære- sounds somewhat like the vowel in English bad, but not exactly
• double consonants like tt in flytte show that the preceding vowel is short

Very rough pronunciation guides:

• utflyttingen ≈ oot-FLYT-ting-en
• flyttevask ≈ FLYT-te-vask
• bærehjelp ≈ BEH-re-hyelp

These are only approximations. The biggest challenge is usually the vowels y and æ, not the overall sentence structure.
