If you have come across the purchase, sale or registration of a garage, you have probably seen a mysterious abbreviation in the documents CAS. What does it mean? Why do some garages belong to CAS, while others belong to MKD? And most importantly, how does this affect your rights as an owner or tenant?

Decoding the CAS is not just a formality, but the key to understanding the legal status of your garage. Taxes, the possibility of redevelopment, connection of communications and even the risk of demolition depend on this. In 2026, issues related to CAS became especially relevant due to tightening control over unauthorized construction and changes to the Urban Planning Code.

In this article we will look at:

  • 🔍 What is CAS and how does this abbreviation stand for in the context of garages
  • 🏢 The difference between CAS and MKD and why it is important for owners
  • ⚖️ Legal risks when purchasing a garage marked CAS
  • 📄 How to check status your garage by cadastral number
  • 💰 Tax consequences and benefits for UAN owners

Misunderstanding the status of a garage can result in fines, problems with registration of rights, or even loss of property. Let's sort things out in order.

1. Decoding CAS: what is it in simple words

CAS is an abbreviation for "Capital building". In the context of garages, it means that the object is recognized non-residential capital structurehaving a foundation, walls, roof and connection to the ground. Such garages are registered in Rosreestr as separate real estate objects and have a cadastral number.

It is important to understand that CAS is legal category, not a technical specification. Even a metal garage on a foundation can be recognized as CAS if it meets the capital criteria:

  • 🧱 Has a strong connection with the ground (foundation, anchorage)
  • 🔨 Designed for long-term use (service life from 10 years)
  • 📏 Has clear boundaries and area (recorded in documents)

Unlike temporary buildings (for example, containers or sheds), UAS garages are subject to mandatory registration in the Unified State Register of Real Estate, and their owners pay property taxes. This is a key difference from garages that are considered “non-permanent” (for example, prefabricated structures).

However, not all permanent garages automatically fall into the UAS category. For example, garages consisting apartment buildings (MCD) or garage cooperatives may have a different status. We'll talk about this further.

2. CAS vs MKD: what is the difference and why is it important

The main confusion arises between UAS garages and garages that are part of MKD (apartment buildings). The difference is fundamental, as it affects:

  • 📝 Procedure for registering rights (via Rosreestr or MKD management)
  • 💸 Tax amount (discounts are often available for MKDs)
  • 🔧 Possibility of redevelopment (MKD requires the consent of all owners)

Let's compare the key parameters in the table:

Criterion CAS (permanent structure) Garage as part of an apartment building
Registration of rights Through Rosreestr (separate object) Through the management of apartment buildings (share in common property)
Property tax Calculated based on cadastral value Often included in housing maintenance fees
Connecting communications Independently (coordination with resource supply organizations) Through the management company MKD
Risk of demolition Low (if the garage is legal) Depends on the status of the MKD land plot
Redevelopment Requires approval from the local administration Requires the consent of all owners of apartment buildings

For example, if your garage is located in the basement of a residential building, it is automatically considered part of the apartment building, even if it has a separate entrance. In this case, you will not be able to sell it separately from the apartment, and the tax will be included in the receipt for housing and communal services.

But a detached garage in the local area, even if it belongs to the owner of the apartment in this house, can be registered as a UAS. This gives more freedom in the disposal of property, but also more responsibility.

💡

If your garage is located on the territory of an apartment building, but is not included in the register of common property, it may be an unauthorized construction. Check your documents: lack of registration in the Unified State Register of Real Estate is a reason to contact the administration for legalization.

Many owners of UAS garages have been using them for years without official registration. However, since 2026, the risks of this approach have increased significantly. According to changes in Town Planning Code of the Russian Federation (Article 222), illegal capital buildings can be recognized unauthorized and subject to demolition at the expense of the owner.

What problems may arise:

  • 🚨 Fines from 20 to 50 thousand rubles for unauthorized construction (Article 9.5 of the Code of Administrative Offenses of the Russian Federation)
  • 🏗️ Demolition by court order (if the garage interferes with landscaping)
  • 💸 Impossibility of sale (buyers will not be able to register ownership)
  • 🔌 Electricity failure (without documents, energy sales companies will not enter into an agreement)

The risks are especially high for garages built on lands:

⚠️ Attention: If your garage is located on a site that is not intended for individual garage construction (for example, on public or agricultural land), it may be considered an unauthorized building even if there is a foundation.

How to check legality:

  1. Request extract from the Unified State Register of Real Estate to the garage (if it is not there, the object is not registered).
  2. Specify the category of land plot in public cadastral map (must be “for garage construction” or “for individual housing construction”).
  3. Check availability building permits (for garages built after 2018).

4. How to register a garage-CAS as your property: step-by-step instructions

If your garage is a permanent structure, but is not properly registered, it can be legalized through the procedure recognition of property rights. In 2026 this can be done by dacha amnesty (extended until March 1, 2031), which simplifies the process.

Step-by-step algorithm:

  1. Check the status of the land plot

    The garage must be located on land intended for garage construction (category ZU GS) or individual housing construction. If the site is leased, issue a buyout or extend the contract.

  2. Order a technical plan

    Contact a cadastral engineer to prepare technical plan (cost - from 5 to 15 thousand rubles). It must indicate:

    • 📏 Garage coordinates
    • 🏗️ Wall and roof material
    • 📌 Link to land plot
  • Submit documents to Rosreestr

    List of documents:

    • 📄 Application for registration of rights
    • 📑 Technical plan (electronic)
    • 💳 Receipt for payment of state duty (350 rub.)
    • 🏡 Documents for the land (if the garage is on a separate plot)

      • Registration deadline— 7 working days.

    • Get an extract from the Unified State Register of Real Estate

      After registration, the garage will receive cadastral number and will become a full-fledged real estate property.

    If the garage was built before 2018 and does not have a building permit, you can use simplified diagram (dacha amnesty). To do this, it is enough to provide:

    • 📜 Declaration of real estate (filled out independently)
    • 📌 Document confirming the right to land
    What to do if the garage is built on someone else's land?

    If the garage is located on a site that does not belong to you (for example, on municipal or private territory without the consent of the owner), it will be extremely difficult to legalize it. In this case there are two options:

    1. Buying out a plot — if the land is municipal, you can try to register it for rent or ownership through an auction.

    2. Relocating a garage - if the site belongs to a third party, the only legal way out is to dismantle and move the building to your site.

    In judicial practice, there are cases when garages on someone else's land were recognized as unauthorized and were subject to demolition at the expense of the owner, even if they had stood for decades.

    5. Taxes on garage-CAS: how much will you have to pay?

    After registering the garage as CAS, the owner will have to pay personal property tax. Its size depends on:

    • 📏 Garage area (the more, the higher the tax)
    • 💰 Cadastral value (set by local authorities)
    • 🏢 Locations (in Moscow and St. Petersburg the rates are higher than in the regions)

    Calculation formula: 

    Tax = Cadastral value × Rate × Coefficient (0.1–0.3)

    For example, for a garage with an area of 20 m² in the Moscow region with a cadastral value of 500 thousand rubles and a rate of 0.1%, the tax will be: 

    500,000 × 0.001 × 0.2 = 100 rubles per year

    However, there are nuances:

    • 🎁 Benefits: pensioners, disabled people and veterans can receive tax exemption for one garage (Article 407 of the Tax Code of the Russian Federation).
    • 📉 Reduction factors: For garages up to 50 m², the rate is 0% in some regions.
    • ⚠️ Fines for non-payment: if the tax is not paid for 3 years in a row, the Federal Tax Service can collect the debt through the court.

    Check the current rate for your region on the Federal Tax Service website or through Taxpayer personal account. If the cadastral value of the garage seems too high, it can be challenged in the Rosreestr commission.

    💡

    Even if the garage is not used, tax must be paid. An exception is garages in disrepair that are declared unsuitable for use (an official conclusion is required).

    6. Is it possible to rebuild or rent out a garage-CAS

    One of the advantages of the UAS garage is the ability to redevelopment or commercial use. However, there are legal restrictions.

    Redevelopment (e.g. second floor extension or workshop extension) requires:

    • 📝 Approvals in the local administration (if changes affect load-bearing structures).
    • 🏗️ New technical plan after completion of work.
    • 💡 Compliance with SNiP (for example, ceiling height is at least 2.2 m).

    Without approval, redevelopment is considered unauthorized, and the garage may be required to return it to its original condition.

    Renting or letting garage-CAS is allowed, but with reservations:

    • 📄 We need to conclude lease agreement and register it with Rosreestr if the period is more than 1 year.
    • 💸 Rental income is taxable Personal income tax (13%), if the amount exceeds 200 thousand rubles per year.
    • ⚠️ It is prohibited to use the garage for living space or production without changing the object category.

    Example: if you rent out a garage for 5 thousand rubles per month, your annual income will be 60 thousand rubles. The tax on this amount is 7,800 rubles (13%). However, if the garage is used by the tenant to store goods (warehouse), this may be recognized misuse and incur a fine.

    💡

    If you plan to rent out your garage for a car service center or workshop, register a change in the type of permitted use (AUR) through the administration. Without this, the activity may be considered illegal.

    7. Buying a garage-CAS: what to look for

    When purchasing a garage marked CAS, check the following points to avoid problems:

    • 🔍 Ownership: request an extract from the Unified State Register of Real Estate. If the garage is not registered, the transaction may be invalid.
    • 🏗️ Land status: the garage must be located on a site with a permitted type of use “for garage construction”.
    • 📄 Tax debts: check via Taxpayer personal account — new debts are transferred to the buyer.
    • 🚗 Access roads: If the garage is in a cooperative, check who is responsible for road repairs and lighting.

    Red flags when purchasing:

    ⚠️ Attention: If the seller asks to complete the transaction through purchase and sale agreement without registration (for example, “on receipt”), this may be fraudulent. Such a garage will not be sold or bequeathed.

    Procedure for checking documents:

    1. Get it from the seller cadastral passport and extract from the Unified State Register of Real Estate.
    2. Check the ownership history: if the garage has changed owners more than once every 2 years, it may be a “problem” object.
    3. Check if there are any encumbrances (seizure, mortgage) through public cadastral map.
    4. If the garage is in a co-op, ask minutes of the general meeting about consent to sale.

    The cost of a garage-CAS depends on:

    • 📍 Locations (within the city - more expensive, on the outskirts - cheaper).
    • 🚗 Availability of communications (electricity, heating, water supply).
    • 📏 Squares (standard garage is 12–20 m², but there are also 50 m² for trucks).

    Average prices in 2026:

    • 🏙️ Moscow and region: 800–2,500 thousand rubles
    • 🌆 Regional centers: 300–800 thousand rubles
    • 🏘️ Small towns: 100–300 thousand rubles

    FAQ: Frequently asked questions about garages-CAS

    Is it possible to build a garage-cas without permission?

    From 2018 for the construction of a garage on your own site no permission required, if:

    • 📍 The plot is intended for individual housing construction or garage construction.
    • 📏 The garage area does not exceed 50 m².
    • 🏗️ Height no more than 3 floors (20 m).

    However, after construction you need notify the administration and register the object in Rosreestr.

    What to do if the UAS garage is recognized as an unauthorized construction?

    There are three options:

    1. Legalize through the court (if the garage does not violate urban planning regulations).
    2. Transfer to another plot (if the land is not yours).
    3. Demolish voluntarily (to avoid a fine).

    The deadline for appealing a demolition decision is 3 months.

    Is it possible to live in a UAS garage?

    No, it's prohibited according to the Housing Code of the Russian Federation. The garage belongs to non-residential premises, and its use for residence may entail:
