If you are letting out a property in Bulgaria, or renting one, the rules are often not where most people expect to find them. This guide walks through the main legal framework for lease agreements in Bulgaria, what each side is actually obliged to do, how deposits, eviction and subletting work in practice, and the tax side for landlords.
Rental relationships in Bulgaria are governed by the Obligations and Contracts Act (OCA), specifically Articles 228 to 239. Unlike many European countries, Bulgaria does not have a separate residential tenancy statute. Both residential and commercial leases fall under the same set of rules in the OCA, supplemented by the general principles of contract law.
That has a practical consequence: the terms of the contract itself carry a lot of weight. The OCA sets the floor, but most of the detail is left to the parties to agree. Where the contract says nothing on a particular point, the default rules in the OCA fill the gap.
Bulgarian law does not require a lease agreement to be in writing for it to be valid. Even an oral rental arrangement is legally binding between the parties. However, a written contract is strongly recommended for several practical reasons:
The registration fee is 0.1% of the total rent payable over the full lease term, with a minimum of BGN 10. Notarisation of signatures is similarly optional. Its main effect is to strengthen the evidentiary value of the contract and to give it a legally established date (достоверна дата). Notarisation on its own does not make the lease opposable to third parties, however, and it is not a substitute for registration. And without any written contract at all, proving the terms of an oral lease in court tends to be extremely difficult, especially where the parties disagree on rent, duration or deposit.
Under Article 229 of the OCA, a lease agreement may not be concluded for a period exceeding ten years, unless it qualifies as a commercial transaction between merchants registered in the Bulgarian Commercial Register. There is no statutory minimum duration, and the parties are free to agree on any term up to the ten-year cap.
If a fixed-term lease expires and the tenant continues to use the property with the knowledge and without objection of the landlord, the lease is deemed to have been converted into an indefinite-term agreement. The original terms of the contract continue to apply, but either party may then terminate with the statutory notice period.
Under the OCA, the landlord (lessor) is bound by the following core obligations:
The parties have a lot of freedom to reallocate maintenance responsibilities in the contract. But certain fundamental defects, particularly those that affect the habitability or safety of the property, can remain the landlord's responsibility whatever the contract says. Courts also tend to look closely at clauses that push too much of the essential maintenance onto the tenant, especially where there is a clear imbalance between the parties.
The tenant (lessee) has the following principal obligations under the OCA:
On the open market, Bulgaria does not have rent control legislation. Landlords and tenants are generally free to negotiate the rent amount without any statutory cap. This applies to both residential and commercial properties. Specific regimes may, however, apply to municipal or public housing, where allocation and pricing can be subject to separate regulation.
Several rules nonetheless constrain how rent may be adjusted:
Bulgarian law does not set a maximum limit on security deposits, nor does it prescribe a detailed statutory regime for their return. The amount, purpose, and return mechanism are left largely to the parties to agree in the contract. In practice, deposits of one to two months' rent are standard for residential leases, though higher amounts are common for furnished apartments or premium properties.
Key points regarding security deposits:
Because the law leaves deposit return procedures largely to the parties, clear contract terms matter: timelines for return, deduction rules, and a move-in/move-out protocol documenting the condition of the property. Tenants should also be aware that if a landlord refuses to return the deposit, recovering it will usually mean going to court. That fact alone tends to shift the negotiating balance in favour of whichever side is already holding the money.
The default rule under the OCA is that subletting is allowed unless the lease prohibits it. Whether a specific sub-arrangement is actually lawful, though, depends on a few things: the scope of the subletting (partial versus full), the intended use of the property, and the terms and purpose of the original lease. A full transfer of use to a third party can be treated differently from partial subletting, and in some cases looks more like an assignment of the lease than a sub-arrangement. That distinction has real consequences for landlord consent and tenant liability, and courts will read the contract in light of what the parties appeared to intend.
Even where subletting is permitted, the original tenant remains fully liable to the landlord under the terms of the original lease. The subtenant's obligations run towards the original tenant, not directly to the landlord. If the contract prohibits subletting and the tenant sublets the property in breach of this provision, the landlord may have grounds to terminate. Given the room for dispute, it is strongly advisable for both parties to address subletting expressly in the lease agreement.
The rules for terminating a lease depend on whether the agreement is for a fixed or indefinite term:
Either party may terminate the lease, regardless of its term, if the other side materially breaches the agreement. Common grounds include:
A landlord in Bulgaria cannot evict a tenant without a court order. Self-help measures such as changing locks, cutting off utilities, or removing the tenant's belongings are not permitted and may expose the landlord to civil liability and, in some cases, criminal prosecution.
The standard eviction process works as follows:
Faster procedures do exist, but only for a narrow slice of claims. The order for payment procedure under the Civil Procedure Code (заповедно производство) can be a useful tool where the claim is primarily monetary, typically unpaid rent, and the supporting documentation is clean. It is not, however, a substitute for eviction. Physically getting the property back will usually still require a civil claim and enforcement through a bailiff. Notarially certified lease clauses can, in narrow circumstances, support expedited enforcement. Which route fits a given case depends on the contract, the evidence, and whether the tenant is going to contest the claim. Contested eviction proceedings in Bulgaria can be lengthy, especially in larger cities where the courts are overburdened, and outcomes tend to vary with the facts and the approach of the individual court.
One further reality is worth stating plainly: in Bulgaria, possession is a major source of practical leverage. Even where the landlord has a strong legal case, getting the property back can take considerable time once procedural steps, appeals and enforcement delays are factored in. Landlords should plan their enforcement strategy early, ideally before a dispute escalates. The flip side applies to occupants too. Staying in possession without a legal basis is not risk-free: it can lead to claims for compensation, damages and costs, and rarely helps the occupant's position in any proceedings that follow.
The effect of a property sale on an existing lease is governed by Article 237 of the Obligations and Contracts Act (ZZD). The outcome depends on whether the lease has been registered with the Property Register, whether it has a legally established date (достоверна дата), who is in possession, when the lease was concluded relative to the transfer, and the good faith of the buyer. In very broad terms:
The concept of достоверна дата can be highly relevant in disputes involving third parties, and practitioners encounter it routinely in this context. Registration remains the strongest form of protection for tenants with longer leases who wish to secure their right to remain in the property if it changes hands.
Landlords in Bulgaria are required to declare rental income and pay income tax. The headline rules for individual landlords are:
A different tax treatment applies where the landlord operates through a company. Legal entities that rent out property are subject to corporate income tax on their profits rather than the 10% flat personal rate, and their deductions, accounting obligations, and reporting cycle are governed by a separate regime. VAT may also apply to certain commercial and short-term lettings, depending on the status of the landlord and the nature of the property. Mixed residential/commercial buildings, serviced apartments, and short-term rental platforms each raise their own compliance issues. Specific tax advice should be sought in those cases.
