Commercial Lease Requirements in Hesse: Clauses and Formal Rules

Commercial leases in Hesse offer extensive contractual freedom but also carry significant risks — particularly the strict written form requirement under BGB § 550. This guide covers essential lease provisions and common pitfalls for landlords.

Key Requirements

1. Written Form (BGB § 550)

The most critical formal requirement for commercial leases:

Requirements

• All essential terms (parties, premises, rent, duration) must be in a single unified document
• Both parties must sign the same physical document
• Amendments and supplements must also comply with written form and reference the main contract
• Annexes (e.g., floor plans, fit-out specifications) must be firmly connected to or clearly referenced in the contract

Consequence of Non-Compliance

If written form is violated, the lease is deemed open-ended. Either party can terminate with approximately 6 months' notice — regardless of any agreed fixed term. This is the "written form termination" risk, representing a significant economic hazard.

Written Form Healing Clauses

Many contracts include clauses obligating parties to cure written form defects before exercising a written form termination. Their enforceability is debated — the BGH has partially invalidated such clauses.

2. Lease Purpose and Use

Precise Definition

The intended use should be exactly specified:

• Type of business (e.g., "office," "retail – textiles," "restaurant with alcohol service")
• Changes in use typically require landlord consent
• The landlord should ensure that building permits align with the agreed use

Non-Competition Protection

• Define clearly whether and to what extent non-competition protection is granted
• Without explicit terms, a basic protection exists by default through case law

3. Essential Contract Clauses

Rent and Operating Costs

• Net cold rent stated separately
• Operating cost prepayment with a detailed cost catalog (extended pass-through permitted in commercial)
• VAT: Clear provisions for VAT option (UStG § 9) and consequences if the tenant's VAT status changes

Security

• Amount and form of the deposit (cash, bank guarantee, corporate guarantee)
• Replenishment obligation upon drawdown
• Return timeline and conditions

See: Commercial Security Deposits.

Maintenance and Repairs

• Clear allocation of duties between landlord and tenant
• Roof and structure clauses for transferring maintenance to the tenant
• Triple-net-lease: Comprehensive cost transfer to the tenant

See: Commercial Maintenance Obligations.

4. Option Rights

Option rights are a cornerstone of long-term commercial leases:

• Renewal option: Tenant's right to unilaterally extend the lease for a defined period
• Exercise deadline: Timeframe for exercising the option (e.g., "12 months before expiry")
• Exercise form: Usually written (to maintain written form compliance)
• Rent at renewal: Market adjustment, index-based, or continuation of current rent

Risks for Landlords

• Missed deadline: If the tenant misses it, the lease simply ends — landlords should actively monitor
• Written form risk: Option exercise must comply with formal requirements

5. Reinstatement and Handover

• Condition at return: Clearly define (e.g., "broom-clean," "original condition")
• Tenant fit-outs: Whether they must be removed or can be retained with compensation
• Handover protocol: Thorough documentation at both move-in and move-out

Best Practices for Landlords

1. Meticulously observe the written form for every amendment and annex
2. Define the lease purpose precisely and verify building permit compliance
3. Structure option rights with clear deadlines and formal requirements
4. Monitor option deadlines actively — missed deadlines can lead to unintended lease termination
5. Have all commercial leases reviewed by specialized legal counsel
