Közös költség is the mandatory monthly condominium fee paid by every apartment owner in a Hungarian társasház (co-owned building). It covers shared building maintenance, a renovation reserve fund, and often heating or hot water in older buildings. In Budapest, fees typically range from HUF 10,000 to HUF 60,000 per month depending on building age, size, and services included.
What közös költség means and who pays it
The phrase közös költség translates literally as “common cost” or “shared cost.” In Hungarian property law, every apartment in a társasház — a building with individually owned units and shared common areas — is legally obligated to contribute to the running costs of those shared areas. This obligation is set out in Act CXXXIII of 2003 on Condominiums (the Társasházi törvény), which governs how Hungarian condominium associations operate.
The fee is paid to the building’s közös képviselő (property manager or building representative), who administers the building’s finances on behalf of all owners. Payment is typically monthly, and the amount is set at the annual közgyűlés (owners’ general meeting) by a majority vote. Renters do not pay közös költség directly — that is the owner’s responsibility, though some landlords pass the cost on through higher rent.
Crucially for foreign buyers: közös költség is not optional and does not disappear when a unit is vacant. If an owner falls behind on payments, the building association has the legal right to place a charge on the property. This makes understanding the fee an essential part of any safe property purchase in Budapest.
What the fee covers — and what it does not
The exact composition of közös költség varies by building, but the law requires that it cover at minimum the costs of maintaining and operating shared (common) areas. In practice, a typical Budapest building’s fee breaks down into two broad buckets: operating costs and the renovation reserve (felújítási alap).
Operating costs generally include: cleaning and maintenance of stairwells, corridors, and courtyards; electricity for shared lighting and lifts; insurance on the building structure; the közös képviselő’s management fee; and in many older panel or pre-war buildings, centrally supplied heating (távhő) and hot water, which are metered separately but billed through the same statement.
What közös költség does not cover: your own apartment’s internal repairs, individual utility contracts (gas, electricity, internet inside the flat), or municipal property tax (építményadó), which is billed separately by the local önkormányzat. Buyers sometimes confuse these, so it is worth requesting an itemised breakdown — called the közös költség kimutatás — from the seller before signing anything.
- Stairwell and corridor cleaning
- Lift maintenance and inspection certificates
- Building insurance (fire, structural)
- Közös képviselő management fee
- Central heating and hot water supply (in many older buildings)
- Renovation reserve contributions
- Garden or courtyard upkeep
- Pest control and waste management contracts
How the monthly amount is calculated
The owners’ association sets the annual budget at the közgyűlés. Total projected costs — maintenance contracts, insurance, reserve contributions, management fees — are added up, and the resulting sum is divided among owners in proportion to their ownership share (tulajdoni hányad). This share is expressed as a fraction of the whole building and is recorded in the land registry (ingatlan-nyilvántartás). A 60 m² flat in a building where the total floor area is 1,200 m² would hold a 1/20 share, for example.
Some buildings calculate the fee per square metre of owned area; others use a flat per-unit split. The method is written into the building’s Szervezeti és Működési Szabályzat (SZMSZ — the condominium’s operational rules). If you are reviewing a listing and only see a total monthly figure, ask the agent to confirm whether central heating is included, because that can represent a large portion of the stated amount in older buildings.
One-off special levies (rendkívüli befizetés) can also be called by the owners’ association for urgent repairs not covered by the reserve fund. These are less common in well-managed buildings with a healthy felújítási alap, but they do occur — particularly in older buildings in Districts V, VI, VII, and VIII where deferred maintenance has accumulated.
Pre-war versus modern buildings: typical fee ranges in 2026
Building type is the single biggest driver of közös költség in Budapest. The table below reflects realistic ranges observed across the Budapest market as of early 2026. Figures include the renovation reserve but exclude individually metered utilities unless noted.
A low közös költség figure on a listing is not always good news. In an unrenovated pre-war building in District VII, a fee of HUF 12,000 per month may simply mean the renovation reserve is underfunded — and a large special levy is overdue.
Buyers comparing Budapest property listings should always request the building’s last three years of financial statements alongside the közös költség figure. This is standard practice and any reputable seller or agent will provide it.
The felújítási alap: the renovation reserve explained
Hungarian condominium law requires that buildings maintain a felújítási alap — a dedicated renovation reserve fund — to cover future major repairs such as roof replacement, façade restoration, lift overhaul, or plumbing upgrades. The amount each owner contributes monthly is decided at the közgyűlés and forms part of the total közös költség payment.
There is no statutory minimum contribution level, which means reserve fund adequacy varies enormously across Budapest. A well-managed building in District XIII might hold several million forints in reserve, while a neglected building in District VIII might have close to nothing. When the reserve is insufficient and a major repair is needed, the owners’ association must either take out a building loan (társasházi hitel) or call a special levy on all owners — sometimes amounting to HUF 300,000–800,000 per unit for a full roof or façade project.
Before purchasing, ask for the current felújítási alap balance and the most recent közgyűlési határozat (meeting resolution) to check whether any major works have been voted on but not yet invoiced. This is one of the due diligence steps covered under a legally structured property purchase.
Red flags to check before you buy
Most problems with közös költség surface during due diligence, not after purchase. Here are the specific documents and facts to verify before exchanging contracts.
- Outstanding közös költség debt on the unit. Ask the seller for a nullás igazolás — a zero-balance certificate from the building manager confirming no arrears. Under Hungarian law, unpaid közös költség can attach to the property, not just the seller personally.
- Felújítási alap balance. Request the current balance in writing. Compare it against the building’s age and condition. A 1920s building with HUF 200,000 in reserve is a concern.
- Voted but unpaid works. Check the last two közgyűlési határozatok for any resolutions approving works not yet started. You could inherit the obligation to pay.
- Underfunded operating budget. If the annual közös költség income does not cover the building’s actual operating costs, the association is running a deficit — a sign of poor management or owner non-payment.
- High arrears rate among owners. If multiple owners are behind on payments, the building’s finances are strained. Ask for the fizetési hátralék kimutatás (arrears report).
How közös költség affects your investment return
For buy-to-let investors, közös költség is a direct operating cost that reduces net rental yield. If you are modelling returns on a District XIII apartment generating HUF 250,000 per month in rent, a közös költség of HUF 35,000 per month represents a 14% reduction in gross income before any other costs. This is why the fee must be factored into yield calculations from the outset, not treated as an afterthought.
The good news is that közös költség is generally a deductible expense against rental income for tax purposes in Hungary, which partially offsets the cost for investors who declare rental income correctly. Consult a Hungarian tax adviser for your specific situation, as the rules depend on how you hold the property — personally or through a company. Our guide on why investors choose Budapest covers the broader return picture, including typical gross yields by district.
Investors targeting higher yields should also consider that new-build apartments in Districts II, XI, and XIII often carry higher közös költség but require less unplanned maintenance, making cash flow more predictable. Older buildings in Districts V and VI can offer strong capital appreciation with moderate fees if the felújítási alap is healthy. There is no universally better choice — it depends on your investment horizon and risk tolerance. Our property management service handles közös költség payments and building liaison on behalf of owners who are not based in Hungary.
If you are actively comparing options, browsing current Budapest apartment sales with the közös költség figure visible on each listing is a practical starting point. Listings that do not show the fee should prompt a direct enquiry before you arrange a viewing.
Frequently asked questions
- Is közös költség the same as a service charge in the UK or HOA fee in the US?
- Functionally, yes. Közös költség is Hungary’s equivalent of a service charge or homeowners association fee — a mandatory monthly payment by apartment owners to fund shared building costs and a renovation reserve. The legal framework is set by Act CXXXIII of 2003 on Condominiums, which is specific to Hungarian law, but the economic purpose is identical to service charges in other countries.
- Can a tenant pay közös költség instead of the owner?
- The legal obligation to pay közös költség rests with the property owner, not the tenant. Some landlords include it in the rent or ask tenants to pay it directly, but if a tenant fails to pay, the building association’s claim is against the owner. Foreign investors renting out Budapest apartments should be aware of this liability and factor the fee into their rental pricing.
- What happens if I do not pay közös költség?
- Under Hungarian law, unpaid közös költség accumulates as a debt that can be registered as a charge (jelzálog) on the property in the land registry. The building association can also pursue legal action for recovery. Arrears also complicate any future sale, as buyers’ lawyers routinely check for outstanding közös költség debt and require a nullás igazolás (zero-balance certificate) before completion.
- Does közös költség include my heating and hot water bills?
- It depends on the building. In panel buildings (panelházak) and some pre-war buildings connected to Budapest’s district heating network (távhő), central heating and hot water are billed through the közös költség statement, metered per unit. In buildings with individual gas boilers, heating is a separate contract between the owner and the gas supplier and is not part of közös költség.
- How often can közös költség be increased?
- The owners’ association can vote to increase the fee at any annual közgyűlés (general meeting), typically held once a year. A simple majority of ownership shares is required. There is no statutory cap on increases, so in buildings with rising maintenance costs or an underfunded reserve, fees can increase significantly from one year to the next. Reviewing the last three years of meeting minutes gives a clear picture of the trend.
- Can I get a breakdown of what my közös költség covers?
- Yes, and you should always request one. The közös képviselő (building manager) is legally required to provide owners with an annual financial statement (éves elszámolás) showing income, expenditure, and reserve fund balance. Before purchasing, ask the seller for this document for the last two years. It is one of the most informative documents in any Budapest property due diligence process.
- Is közös költség tax-deductible for rental investors in Hungary?
- Generally yes — közös költség is considered an operating cost of a rental property and can be deducted from rental income when calculating taxable profit in Hungary. The exact treatment depends on whether you hold the property personally or through a Hungarian company, and Hungarian tax rules can change. Always confirm the current position with a qualified Hungarian tax adviser before filing.
- What is a realistic közös költség for a 50 m² apartment in District XIII?
- For a 50 m² apartment in a well-managed modern building in District XIII — one of Budapest’s most active residential districts — a realistic közös költség in 2026 is approximately HUF 25,000–40,000 per month. This typically includes the renovation reserve and building management, but not individual utilities. Older buildings in the same district may be lower but with a weaker reserve fund.
