The question of the number of floors in a garage arises among owners of private houses, entrepreneurs and even municipal services. On the one hand, a multi-level garage saves space on the site and allows you to place more cars or organize additional rooms. On the other hand, strict building codes, fire safety and legal restrictions dictate strict limits. In this article we will look at how many floors can a garage have? in 2026, taking into account the type of construction, purpose and regional characteristics.

It is important to understand that the answer depends on several factors: private or commercial garage, whether it is located within the city or outside it, as well as what functions it performs. For example, a garage for a personal car with an attic and a parking garage for 50 cars are regulated by different standards. We analyzed the current SNiP 21-02-99*, SP 4.13130.2013 and regional amendments to provide a clear answer with example projects.

1. Standards for private garages: 1–3 floors

For individual garages built on land individual housing construction (individual housing construction) or Private household plots (personal subsidiary plot), the most loyal rules apply. According to SNiP 30-02-97* (clause 5.3), the height of such a garage should not exceed 10 meters - this is the equivalent of 3 full floors, taking into account interfloor ceilings. However, in practice, most projects are limited to 1–2 floors.

The reasons are simple:

  • 📏 Ceiling height: minimum floor height in the garage is 2.2 m (for comfortable movement). When parking with a lift or truck, 2.5–3 m is required.
  • 🔥 Fire safety: Garages above 2 floors require installation automatic fire extinguishing system (ASPT) or alarm, which increases the cost of the project.
  • 🏗️ Foundation: multi-storey buildings need reinforced strip or slab foundations, especially on heaving soils.

At the same time attic (attic floor with sloping walls) is not considered a full floor if its height to the roof ridge does not exceed 1.8 m. This allows you to “bypass” the restrictions and build a garage with parking on the 1st floor and a workshop or storage room in the attic.

⚠️ Attention: In Moscow and St. Petersburg, additional restrictions apply - garages above 2 floors require approval from Committee on Architecture, even on private plots. In the regions, the rules are softer, but check with your local administration.

2. Commercial garages and parking lots: up to 9 floors

For multi-level parking (public, underground or aboveground) standards are stricter, but the possibilities are wider. According to SP 113.13330.2016, the maximum number of storeys depends on the type:

Garage type Max. number of storeys Requirements
Above ground outdoor parking 9 floors Ramps, elevators for the disabled, ventilation are required
Closed mechanized 5 floors Automatic parking systems, fire compartments
underground 3 floors Waterproofing, emergency lighting, backup exits
Garage parking with boxes 4 floors The width of passages is at least 6 m, fire-resistant partitions

The key difference between commercial garages is the mandatory presence fire compartments (no more than 3 floors in one compartment) and escape routes. For example, in underground parking lots on each floor there must be at least 2 outputs, separated from each other by 40+ meters.

An example of successful implementation is parking Afimall City in Moscow (7 above-ground floors) or "Lakhta Center" in St. Petersburg (5 underground levels). Such projects are taking place state examination and require investment in engineering systems.

3. Underground garages: why they are rarely built above 3 floors

Underground garages seem like an ideal solution for saving space, but in practice their number of storeys rarely exceeds 3 levels. Main reasons:

  1. Waterproofing: Each additional floor increases the risk of leaks. For example, in SP 28.13330.2017 it is stated that at a depth of more than 5 m it is required double waterproofing with drainage system.
  2. Ventilation: underground parking lots must be equipped supply and exhaust system with backup fans. The cost of such equipment grows exponentially with each floor.
  3. Psychological factor: Drivers avoid deep underground parking lots due to fear of getting stuck or poor connection (there is often no mobile network at a depth of 10+ m).

Exception - automated parking (for example, in Japan or Singapore), where cars are moved by robots without the participation of a driver. In Russia, such projects are just beginning to appear (for example, "Parking on Poklonnaya Hill" in Moscow with 4 underground levels).

⚠️ Attention: Construction of an underground garage more than 3 m deep requires geological surveys — without them the project will not be approved. In some regions (for example, in Leningrad region) due to the high groundwater level, underground garages are completely prohibited.

Even if the standards allow you to build a garage on 3 floors, its legalization will require the collection of documents. Main stages:

Urban site plan (GPZU)|Project documentation with the signature of the architect|Conclusion on fire safety|Building permit (for objects above 2 floors)|Commissioning certificate-->

Pay special attention land categories:

  • 🏡 On individual housing construction You can build a garage of up to 3 floors without additional approvals (if it does not exceed 10 m in height).
  • 🏢 On commercial lands design documentation and expertise are required.
  • 🌳 On gardening plots (SNT) garages above the 1st floor are often prohibited by the charter of the partnership.

If the garage is adjacent to a residential building (for example, built-in), its number of storeys should not exceed the number of storeys of the house. For example, for a 2-story cottage, the maximum garage is also 2 floors.

What happens if you build a garage without approval?

An illegal building cannot be registered as a property; it cannot be sold, bequeathed or used as collateral for a loan. In addition, following a complaint from neighbors or an inspection by the administration, such a garage may be forced to be demolished through the court (Article 222 of the Civil Code of the Russian Federation).

5. Practical examples of projects

Let's consider real projects of garages with different number of storeys in order to evaluate the pros and cons of each option.

📌 One-story garage (6×4 m)

Pros:

  • ✅ Minimum construction costs (from 300 thousand rubles).
  • ✅ Does not require approvals (if it does not exceed 5 m in height).
  • ✅ Suitable for areas with high GWL (groundwater level).

Cons:

  • ❌ Limited area (maximum 2 cars + inventory).
  • ❌ There is no way to organize a workshop or pantry.

📌 Two-story garage (6×6 m) with attic

Features:

  • 🚗 1st floor: parking for 1–2 cars.
  • 🔧 2nd floor (attic): workshop or gym.
  • 💰 Cost: from 800 thousand rubles. (with insulation and engineering systems).

This project is popular in Moscow region and Leningrad region, where the plots are small and the need for additional premises is high.

📌 Three-story commercial garage (10×15 m)

For whom: car services, car sharing companies, parking lots at shopping centers.

Requirements:

  • 🔥 Fire alarm and deluge plants.
  • 🚪 Evacuation stairs and ramps for the disabled.
  • 📄 Project documentation with expertise (cost from 1.5 million rubles).

Example: garage for 12 cars in Kazan (3 floors, total area 300 m²) cost the owner 6 million rubles, but paid off in 3 years thanks to rental.

💡

The higher the garage, the higher the costs for engineering systems (ventilation, fire safety, foundation). The optimal balance for private owners is 2 floors with an attic, for business - 3–4 floors with automatic parking.

6. Alternative solutions: when there are few floors

If the standards limit the number of floors, but there is a catastrophic lack of space, consider alternatives:

  • 🅿️ Mechanical parking: automatic systems (for example, «ParkPlus») allow you to place up to 10 cars on an area of 30 m².
  • 🏗️ Modular garages: prefabricated structures from LSTK (light steel thin-walled structures) can be increased in width, not height.
  • 🚪 Transformer garages: lifting platforms (e.g. «LiftPark») allow you to park 2 cars in one box.

The cost of such solutions is higher than that of a traditional garage, but they often turn out to be more profitable than fighting with bureaucracy for permission to the 4th floor.

Example: in Sochi due to restrictions on high-rise construction, many hotels use underground roboparking - they take up 3 times less space than a regular garage and do not spoil the view of the sea.

7. Common mistakes when building multi-story garages

Even experienced developers make mistakes, which later become costly. Here are the most common:

  1. Ignoring the geology of the site: for example, construction of a 3-story garage on peat soils without a pile foundation leads to subsidence of the walls.
  2. Saving on ventilation: accumulates in closed garages carbon monoxide (CO), which is life-threatening. The minimum air exchange is 180 m³/h per parking space.
  3. No fire compartments: in garages larger than 500 m², each compartment must be separated fire partitions (REI 60).
  4. Incorrect layout: narrow passages (less than 3 m) make maneuvering difficult, especially for large vehicles.

To avoid mistakes, order terms of reference (TOR) from an architect with experience in garage design. The average cost of technical specifications is from 30 thousand rubles, but this will save hundreds of thousands on rework.

⚠️ Attention: If you are building a garage on slope, please note that each floor must have a separate entrance/exit. For example, in Krasnodar region There are cases when garages on hills with one ramp were considered unsafe due to the impossibility of evacuation in case of fire.
💡

Before starting construction, check the site for the presence of communications (gas pipeline, water supply) - their intersection may prohibit the construction of a garage or require transfer to your account.

FAQ: Answers to frequently asked questions

Is it possible to build a 4-story garage on your site?

Technically yes, but legally it is almost impossible. For private plots (individual housing construction, private plots) the maximum height is 10 m (3 floors). For 4 floors you will need to transfer the land to the category commercial use and undergo state examination, which takes 1–2 years and costs from 500 thousand rubles.

Do I need to coordinate the garage with the attic?

If the attic is not residential (for example, a storage room or workshop) and its height to the roof ridge does not exceed 1.8 m, approval is not required. But if you are making a full second floor (ceiling height 2.2+ m), you will have to obtain a building permit.

What taxes are paid for a multi-story garage?

For private garages with an area of up to 50 m², no tax is charged (Article 407 of the Tax Code of the Russian Federation). If the garage is larger or commercial, the tax is calculated according to cadastral value (on average 0.1–0.3% per year). For example, a garage in Moscow with an area of ​​100 m² will cost 5–15 thousand rubles. tax annually.

Is it possible to make a living room in a garage?

Formally, no. According to SNiP 02/31/2001, residential premises cannot be located above garages or in the same building with them due to the risk of poisoning from exhaust gases. However, in practice, many people bypass this rule by designing the room as a “guest house” or “change house.” Risk - fine up to 50 thousand rubles. when checking.

How much does it cost to build a 3-story garage?

The cost depends on the materials and region:

  • 🧱 Brick: 1.2–1.8 million rub. (turnkey).
  • 🏗️ Frame (LSTC): 800 thousand–1.2 million rubles.
  • 🏢 Monolithic concrete: 2–3 million rubles. (for commercial projects).

Additionally, you will have to pay for the project (50–150 thousand rubles) and approvals (200–500 thousand rubles).
