Maintenance Obligations and Interface Matrices in Commercial Leases

The use of a commercial space (office, logistics hall, restaurant) consumes surfaces and equipment heavily beyond the limits of customary private housing. Via authorities or under the threat of property managers' wallets, numerous dispute court restrictions are fought over the question: Does the B2B company tenant pay for the breakdown of the cooling air source heat pump, or the hosting landlord company taking from the investor's wallet?

Disclaimer: This guide provides general legal information. The division of responsibilities is sharply determined by the language of the contract document and its appendices. Always order high-quality B2B interface matrices for property regulations from a lawyer. Information last verified: March 2026.

Legal Default - The LHVL Starting Point

The provision of Section 18 in the Act on Commercial Leases instructs that if matters have been completely silent in the contract papers, the apartment must be in such a condition as the value classification of the business operations requires, and the responsibility for maintaining this condition and paying for normal equipment wear and tear falls by law as a Default "payable by the Landlord" just like in consumer homes.

However, in the Finnish commercial space B2B world, this scenario very rarely becomes reality for the owning company. B2B freedom dictates: Almost all the maintenance of the interior spaces and indoor shell equipment is contractually transferred 100% to the tenant company's financial responsibility.

Typical Division of Responsibilities (Contract Practice in Commercial Spaces)

1. Structures and Outer Surfaces (Owner's Responsibility)

The major renovations maintaining the core value of the real estate and the demands of massive justifications fall to be paid from the profit margin of B2B landlords as the long-term development of the company:

• Roof renewals and roof leaks (Outer shell).
• The radiators of the property's basic heating network or large company-wide sewer systems.
• Painting of exterior walls or plinths.
• Maintenance of external glass and massive framing. (If, however, vandalism breaks the glass, the tenant's vandalism insurance usually seeks compensation due to the heavy protection requirements set by the contract).

2. Inner Surfaces, Equipment and Care (Tenant's Responsibility)

In industrial halls, offices, and grocery stores, the contract overrides LHVL and slaps the so-called inner maintenance and damage compensation cost onto responsibility through a broad B2B insurance-space responsibility.

• Building technology equipment in the Commercial Space: The renewal of automatic door motors upon breaking down, the maintenance and complete replacement to a new one of the commercial space-specific exhaust air pump and vestibule fan belong to a typical contract to the tenant ("Everything that the tenant's business exclusively burdens or the space requires - including refrigerators, cold displays...").
• Wear and tear and repainting of interior walls.
• Renewal of keys and locks.

Interface Matrix (Vastuunjakotaulukko / Gränssnittslistan)

Especially in office centers, listing individual clauses (such as "who pays for the purchase of a new HVAC filter") by the page directly into the contract is confusing. Professionals in the industry equip the contract with a fixed "Interface Matrix" Appendix (Vastuunjakotaulukko). This is a massive Excel/PDF grid, which ticks off with clear X marks every compressor, fluorescent tube series, and floor molding next to it, whether the Renewal/Maintenance is paid by Business ID (Company-Tenant) or O (Landlord-Owner). This immediately prevents expensive HVAC equipment disputes by looking at just one paper when a dispute arises.

Handover Condition - Returning the Spaces "To Original"

Finnish law permits a broad dismantling condition: If the tenant has had their own social facility kitchens built into the B2B warehouse during a 10-year period, the Landlord basically has a 100% permissible demand protected by a contract condition to force the entrepreneur to tear down the kitchens at their own expense to empty concrete walls, or to pay the demolition bill via invoicing back at the starting moment. This is related to the B2B prerequisite's free alteration right and its accompanying reconversion.

Landager Removes Equipment Disputes and Paywalls

A dishwasher breaks down in your large B2B complex and the restaurant innocently blames expecting a maintenance man from the landlord with costs. An oblivious construction manager orders a maintenance bill on your behalf without realizing the boundaries of the contract! Landager's digital maintenance controller links the ticket of the "Interface Matrix" directly to the target notification. When the B2B restaurant logs in to create a "Washing machine broken" notification, the platform automatically illuminates a red cross for the notifier: ”According to table-ID 4A, this equipment violation is classified under the Tenant Company's own responsibility - Make the direct work order to your equipment insurance yourself!” You save your foremen hundreds of unnecessarily ordered billed hours right on the same day.
