Commercial premises in an apartment building: business rent, operating duty and turnover rent

Ground floor shops, offices, warehouses, workshops and practices often drive the economics of an Austrian apartment building more than the residential units above. Their contracts are rarely standardised. Data rooms typically contain a patchwork of legacy leases with waivers of termination, individually negotiated amendments, operating duties, turnover rents and non-competition clauses. Reviewing commercial leases as if they were apartments misses the true value drivers.

This article maps the key review points. It covers the tenancy law scope, the contract purpose, operating duty, turnover rent with a minimum floor, non-competition and industry protection as well as handback and handover duties. VAT option issues are treated in a separate article so that responsibilities in the data room stay visible.

Why commercial premises deserve their own review layer

Commercial units in an apartment building often carry a disproportionate share of the income. Their value depends on what the underlying lease allows. A commercial lease that fails to regulate business operations, product range, opening hours, turnover rent, non-competition or handback opens debates between seller, buyer and tenant that a later amendment can rarely repair.

For that reason commercial premises belong in a review layer of their own with a dedicated schedule. Only then do the value drivers become visible. VAT clauses for commercial premises and business premises permit questions are separate review layers; a general overview of the lease stock sits on the topic page rent roll and lease agreements.

Tenancy law scope and contract purpose of commercial units

Whether and to what extent the Austrian Tenancy Act applies to a commercial unit follows section 1 MRG and its exceptions. Apartment buildings with multiple residential and commercial units often fall under full application, but the classification must be evidenced per unit. Later attic conversions or extensions may sit in a different category. A blanket classification for the whole property is rarely defensible.

The contract purpose also shapes which uses the tenant may actually perform and which alterations are permitted. Section 1096 ABGB obliges the landlord to enable the agreed use. A narrowly drafted purpose makes range extensions or repurposing without landlord consent difficult. A broadly drafted purpose from the landlord's perspective needs to be accompanied by evidence duties and audit rights.

Review is best organised in a per-unit matrix listing scope, contract purpose, actual use, alterations, open permits and historic amendments. Only this structure shows where a sale contract assurance is supported and where a disclosure is required.

Operating duty: scope, exceptions and evidence

An operating duty follows primarily from the contract and may require the tenant to run the business during specified opening hours and within a defined range. It may, however, also arise from the interpretation of the contract, in particular where the evident business purpose and the parties' intentions at the time of contracting require continuous operation. An express clause is more reliable because it establishes the scope and sanctions clearly. Its purpose is to maintain footfall, bind an anchor tenant and secure the concept of the other commercial units.

The clause's scope and limits are decisive. How many opening days per week are required, which product ranges are covered, which exceptions apply to alterations or public holidays, which sanctions are envisaged and which evidentiary rules apply. Without an adjustment path, an operating duty can quickly become untenable in changing markets or economically unbearable for the tenant.

For the buyer, it matters whether the operating duty binds after the change of ownership and how it feeds into the income model. A prior landlord waiver, an informal past practice or a de facto reduction of opening hours can erode the clause. The principles collected on the topic page rent roll and lease agreements assist the evidentiary review.

Turnover rent: minimum rent, definition and evidence

Turnover rents typically combine a fixed minimum rent with a turnover-based supplement from a defined threshold. Clause quality stands and falls with a precise definition of turnover. Net or gross, inclusion or exclusion of online sales, deductions and treatment of inter-store movements are typical issues. A well-drafted clause resolves them in the wording.

Reporting and audit rights of the landlord are equally decisive. Monthly or quarterly reports, an annual reconciliation, audit rights via an appointed auditor and legal consequences for non-delivery must be tightly drafted. Without audit rights, turnover rent becomes practically uncontrollable. For valuation, the turnover portion should only enter the price with a documented history.

For buyers, the review must also cover which reports already exist, which arrears are pending and whether audit rights have been exercised. The sale contract should address the transition of the reporting period, the allocation of payments and protection against understated turnover. The apartment building risk check can support prioritisation.

Non-competition and industry protection clauses

Non-competition and industry protection are frequent components of ground floor leases. They may oblige the landlord not to let another unit in the same building or within a defined radius to a direct competitor. The geographical, subject-matter and temporal scope must be clear. Otherwise, competing clauses collide when new units are let or the building is sold.

For the buyer it matters whether such clauses exist and how they restrict the re-letting potential of other units. A properly inventoried clause becomes a reliable income input. A hidden clause in a template can trigger damages or extraordinary termination once a new tenancy is signed.

Sellers should check whether the stock contains competing industry or non-competition clauses. If so, a specific reference belongs in the disclosure letter and the sale contract guarantee so that no consolidated assurance risk arises.

Tenant change, business sale and section 12a MRG

For commercial premises in full application, section 12a MRG entitles the landlord to raise the main rent to the appropriate level under section 16(1) MRG when the tenant transfers the business operated on the premises to a third party. Both the transferor and the acquirer of the business must notify the landlord without delay; the landlord then has a six-month window from notification to demand the increase to the appropriate rent, taking into account the nature of the business. For valuation, it is important to review whether such a situation is pending, already implemented or whether an uplift notice has already been issued.

Similar questions arise when there is a change of control within a tenant company or a restructuring. Not every transfer triggers section 12a MRG, but many constellations are contentious. The lease should clarify how group movements, management buyouts and family transfers are handled.

For buyers, this review level belongs in the income projection. A theoretical uplift right without realistic use is worth little; a notice already issued is a concrete building block. Related issues on tenant change are collected on the topic page rent roll and lease agreements.

Handback, restoration and compensation for fit-outs

At the end of every commercial lease, questions of handback, restoration and compensation arise. Section 1109 ABGB requires the return of the premises in the agreed condition. Contractual add-ons typically require removal of fit-outs, dismantling of signage and restoration of a defined starting condition.

For sellers, it matters which handback duties bind the tenant and what economic significance they carry for the buyer. Compensation for fixtures or customer base is often negotiated between outgoing and incoming tenants. The landlord's lease should describe this transparently. Confusion with a prohibited premium under section 27 MRG should be avoided.

For handover, a per-unit binder with layout, tenant fit-out, landlord contributions, handback duty and current condition is recommended. On that basis, handover records along the lines of the topic page handover and effective date can be prepared.

Buyer package and guarantees for commercial units

For a defensible buyer decision, each commercial unit should contribute the following to the data room: the current lease with all amendments, the documented tenancy scope, actual operation and opening hours, turnover history with evidence, arrears, deposit, open landlord commitments, business premises permit and current correspondence. Only with that structure can differentiated guarantees be drafted.

Buyers should avoid blanket operating or turnover guarantees and instead work with a unit annex, disclosure items and targeted purchase price retention. Sellers protect themselves by carefully limiting the knowledge concept and openly describing contract variants in the data room. For prioritisation and scoring, the apartment building risk check can help.
