Thuringia Commercial Property Law: A Landlord's Guide

Commercial property leases in Germany — and in Thuringia — are governed by the principle of freedom of contract, as established in the German Civil Code (Bürgerliches Gesetzbuch – BGB), which originally came into force on 1 January 1900. Unlike residential tenancies, German law assumes that business parties negotiate from a position of relative equality and therefore provides significantly fewer mandatory protections. This gives both landlords and tenants in Thuringia substantial flexibility to structure commercial leases to suit their commercial needs.

Key Differences: Commercial vs. Residential Tenancies in Thuringia

Security Deposits — No Cap

The three-month deposit limit of § 551 BGB explicitly does not apply to commercial tenancies (§ 578 BGB does not extend it to businesses). Deposits of three to six months' gross rent are common, varying with the level of tenant investment and buildout.

See the Commercial Security DepositsPreview unavailable guide for full details.

Rent Increases — Contractually Driven

No statutory equivalent of the Kappungsgrenze or Mietpreisbremse applies in commercial tenancies. Rent can only change by mechanisms already written into the lease — typically index clauses (tied to Germany's Consumer Price Index) or graduated rent steps. Without such a clause, rent is fixed for the entire contractual term.

Lease Terms and Termination

Commercial leases are usually fixed-term — commonly 5, 7, or 10 years with tenant renewal options. Ordinary termination before the end of a fixed term is legally excluded for both parties; only extraordinary termination for serious cause is available mid-term.

For indefinite-term commercial leases, § 580a BGB provides that either party may terminate by the third working day of a calendar quarter, effective at the end of the next calendar quarter (approximately six months' effective notice). No justification is needed (unlike residential tenancy terminations).

The Written Form Requirement — A Critical Risk

Fixed-term commercial leases exceeding one year must be in text form under § 550 BGB (as applied via § 578 BGB). If not concluded in text form, the contract is deemed to be for an indefinite period. This means that all material terms, annexes, and amendments should be documented in a way that allows for permanent storage and reproduction of the text, and the identity of the person making the declaration is clear. Any non-textual later amendment (e.g., oral agreement) can cause the entire lease to be deemed an indefinite-term contract — exposing both parties to early termination.

Maintenance and Repairs

While the landlord's fundamental maintenance duty under § 535 BGB applies to commercial premises too, commercial leases regularly carve out large sections of that duty and transfer it to the tenant — using "shell-and-core" (Dach und Fach) clauses. These clauses can be valid in individually negotiated contracts even in forms that would be deemed unfair in a residential tenant context.

Late Fees and Arrears

Commercial landlords benefit from higher statutory default interest (9 percentage points above the base rate vs. 5 for residential) and a flat-rate €40 recovery fee per default event under § 288 BGB.

See the Commercial Late FeesPreview unavailable guide.

Disputes and Jurisdiction

In Thuringia, jurisdiction for commercial lease disputes depends on the amount in dispute (Streitwert). For claims up to €5,000, the Local Court (Amtsgericht) has jurisdiction, while the District Court (Landgericht) (e.g., LG Erfurt, LG Gera, LG Meiningen, or LG Mühlhausen) handles claims exceeding this amount (§ 23, 71 GVG).
