Commercial Lease Law

Commercial Lease Law governs the legal relationship between landlords and tenants in the leasing of premises for commercial purposes-such as offices, retail stores, warehouses, medical practices, or manufacturing facilities. Unlike residential tenancy law, commercial tenancy law offers far less statutory tenant protection: There are no rent caps, no protection against termination under social tenancy law, and no legally prescribed deadlines for settling operating costs. Instead, the principle of freedom of contract applies-both parties are largely free to structure the relationship as they see fit.

Key Differences from Residential Leases

In commercial lease law, there are no caps on rent increases, no moratorium periods, and no special right of termination for tenants following a rent increase. Notice periods and grounds for termination are agreed upon contractually; the statutory provision of § 580a BGB applies only subsidiarily. Commercial tenants must rely on the terms of the lease agreement-if a provision is missing, gaps may arise that are often interpreted to the disadvantage of the weaker contracting party. Particularly important: freedom of form applies only to leases of up to one year; longer leases must be concluded in writing (Section 550 BGB), otherwise they are deemed to be open-ended.

Another key difference lies in the allocation of operating costs. Residential tenancy law precisely regulates which costs may be passed on to the tenant (Operating Costs Ordinance). In commercial tenancy law, the parties may allocate nearly all types of costs-including maintenance reserves, administrative costs, and comprehensive insurance costs. This flexibility is an advantage for landlords but requires careful and comprehensive contractual drafting.

Typical Contract Clauses in Commercial Lease Agreements

Index-linked rent clauses tie the rent to the consumer price index and no longer require approval from the Deutsche Bundesbank (this requirement was eliminated with the repeal of the Price Clause Ordinance in 2007). Revenue-based rent clauses link the rent entirely or partially to the tenant’s revenue. Step-up rent clauses establish fixed rent increases for future periods. Also important are provisions regarding cosmetic repairs, operating cost allocations (triple-net vs. gross rent), subletting, and renovation rights.

The issue of renewal options is particularly significant. Many commercial tenants negotiate option rights that give them the right to extend the lease for additional years under the same or similar terms. For landlords, this provides planning security but also limits flexibility. Careful drafting of the option clause-including the exercise period and rent adjustment mechanism-is therefore essential.

Termination and Eviction in Commercial Lease Law

Commercial lease law distinguishes between ordinary and extraordinary termination. Ordinary termination is governed by the terms of the lease agreement; if no provision exists, the statutory notice period under § 580a BGB applies (six months to the end of the quarter for annual rent exceeding 4,000 euros). Extraordinary termination for good cause is possible, for example in the case of significant rent arrears. Eviction proceedings against commercial tenants are often protracted in practice; a surety or security deposit protects the landlord.

Eviction proceedings for commercial leases can take several months. In the meantime, rent continues to accrue-or is lost if the tenant is insolvent. We therefore recommend a security deposit equal to three to six months’ net rent, as well as a personally enforceable guarantee from the managing director for GmbH tenants. These safeguards are often overlooked in the initial rush of negotiations, but especially for new commercial leases, the tenant’s credit check and contractual safeguards are essential.

Leased Area and Area Calculation

A common point of contention in commercial lease agreements is the definition of the leased area. Unlike residential leases, there are no binding calculation regulations. The gif guideline (Society for Real Estate Research) for office space or the MF-G for commercial space in general are widely used. Whether common areas, utility rooms, wall thicknesses, or balconies are included in the leased area is purely a matter of contract. Missing or unclear definitions of area regularly lead to disputes regarding the settlement of operating costs or rent increases based on the price per square meter.

Practical Tip for Property Owners in Nuremberg and Franconia

Landlords of commercial spaces in Nuremberg should always have their lease agreements reviewed by an attorney specializing in commercial lease law. Particularly in downtown Nuremberg and in gentrified commercial areas (Gostenhof, Kulturwerkstatt), commercial lease agreements are often too brief or too vaguely worded, leading to disputes over operating costs, renovation measures, or renewal rights. We recommend a written lease term of at least five years with a clear indexation clause and an option to renew.

The Nuremberg commercial real estate market has undergone structural changes in recent years: While traditional retail spaces in B-locations are under pressure, office spaces in central locations and industrial warehouses in the surrounding areas remain in high demand. Landlords of commercial spaces should adjust the lease term and indexation clause to the current market situation and incorporate regular rental market analyses into their leasing strategy.

Frequently Asked Questions

Does the rent cap also apply to commercial spaces?

No. The rent cap applies exclusively to residential lease agreements. There is no statutory rent cap for commercial leases; the market price is determined solely by supply and demand.

As a commercial landlord, do I have to prepare a statement of operating costs?

Only if the lease provides for the allocation of operating costs and a statement has been agreed upon. Unlike in residential tenancy law, there is no statutory annual deadline for the statement. Clear contractual provisions are strongly recommended.

Can a commercial tenant terminate the lease for cause if the premises are defective?

Yes. In the event of significant defects that impair the contractual use of the premises, and after an unsuccessful deadline has been set for remedying the defects, the tenant is entitled to terminate the lease for cause (Section 543 of the German Civil Code (BGB)). In the commercial sector, the threshold for what constitutes a “significant defect” is assessed strictly.

What applies if there is no written lease agreement?

A commercial lease agreement that is not in writing is deemed to have been concluded for an indefinite term if its duration exceeds one year (Section 550 of the German Civil Code (BGB)). This means: Although the agreement is valid, it can be terminated at any time with the statutory notice period-regardless of any verbally agreed-upon longer term. For landlords, this poses a significant risk when making long-term investments in the property’s condition.
