Общее имущество требует ремонта.

Yes, it often refers to a group of things, but имущество is a singular collective noun in Russian.

So grammatically, Russian treats it as one singular noun:

• имущество требует
• not имущество требуют

This is similar to how English can use a singular word for a collection, like property or equipment.

In this sentence, общее имущество means something like the shared/common property as a whole.

Because общее has to agree with имущество.

The noun имущество is:

• neuter
• singular
• nominative

So the adjective must also be:

• neuter
• singular
• nominative

That gives:

• masculine: общий
• feminine: общая
• neuter: общее

So:

• общее имущество = correct

Because the subject общее имущество is grammatically singular.

The verb требовать in the present tense changes by person and number:

• я требую
• ты требуешь
• он / она / оно требует
• мы требуем
• вы требуете
• они требуют

Since имущество is singular and neuter, Russian uses the same form as with оно:

• общее имущество требует

Ремонта is in the genitive case.

The verb требовать usually takes the genitive:

• требовать чего?
• требовать ремонта
• требовать помощи
• требовать ответа

So in this sentence:

• общее имущество требует ремонта

Not:

• требует ремонт

This is a very common Russian pattern, and it is worth learning as a set:

• требовать + genitive

Yes, very much so.

Russian often uses требовать + genitive to mean to need / to require something, especially in formal or practical contexts.

Very common examples:

• Дом требует ремонта.
• Машина требует замены деталей.
• Документ требует проверки.

So требует ремонта is a natural, standard phrase meaning that something needs repair.

Yes. That would also be correct:

• Общее имущество нуждается в ремонте.

This means almost the same thing, but the structure is different:

• требовать + genitive → требует ремонта
• нуждаться в + prepositional → нуждается в ремонте

Both are natural, but there is a slight stylistic difference:

• требует ремонта sounds a bit more formal, factual, or administrative
• нуждается в ремонте can sound a little softer or more descriptive

In housing, legal, and official contexts, требует ремонта is especially common.

In many real-life contexts, especially housing or legal language, общее имущество usually means common/shared property, not just “general property.”

For example, in an apartment building it can refer to shared areas or shared infrastructure such as:

• entrances
• stairwells
• elevators
• roof
• pipes
• hallways

So while общее literally comes from the idea of common/general/shared, the most natural interpretation here is usually common property or shared property.

Because Russian does not have articles like a and the.

So:

• Общее имущество требует ремонта.

can mean:

• The common property needs repair
• Common property needs repair
• The shared property requires repairs

Which English version is best depends on context, but Russian itself does not mark that distinction with articles.

Yes. Russian word order is flexible, although not completely free.

The neutral order here is:

• Общее имущество требует ремонта.

But you might also see:

• Ремонта требует общее имущество.

This version puts more emphasis on ремонта or sounds more formal/stylistic.

For a learner, the safest default is to use:

• subject + verb + complement
• Общее имущество требует ремонта.

They are different case forms of the same noun.

Base form:

• ремонт = nominative singular

In this sentence:

• ремонта = genitive singular

So the change is grammatical, not a change in core meaning.

You can think of it like this:

• dictionary form: ремонт
• after требовать: ремонта

The stress is:

• О́бщее иму́щество тре́бует ремо́нта.

A rough pronunciation guide:

• О́бщее → OB-shchee
• иму́щество → ee-MOO-shchest-va
• тре́бует → TRE-boo-yet
• ремо́нта → re-MON-ta

A couple of notes:

• щ in общее and имущество is a soft shch sound
• е after a soft consonant can sound a bit like ye
• unstressed vowels are reduced in real speech, so pronunciation is not always exactly like the spelling

Yes, it sounds fairly neutral-to-formal.

It is especially natural in:

• official statements
• housing management
• maintenance reports
• legal or administrative writing

In casual speech, a person might say something simpler like:

• Тут нужен ремонт.
• Это надо ремонтировать.

But Общее имущество требует ремонта sounds perfectly normal in formal or written Russian.
