Commercial Lease: Diagnostics (DDT) and Required Disclosures

When renting non-residential property in France, real estate transactions require much more than simply handing over a key. The legislative philosophy is to establish absolute visibility over the charges that could burden the warehouse's activity and overwhelm the balance sheet of the "commercial tenant." The Environmental Code and the Commercial Code compel the landlord to provide an impressive registry of documents.

Disclaimer: A simple omission of the ERP (State of Risks and Pollution) on a SEVESO site is a serious source of cancellation for the entire legal operation of the premises based on commercial law. Always use a verified tertiary diagnostic firm (COFRAC Approved and heavily insured). Guide verified: March 2026.

1. The State of Risks (ERP) — Environmental Law

Every premises, from the small Parisian storefront in a protected flood zone along the Seine to the gigantic steel warehouse in the Rhône corridor, has a label regarding Mother Nature:

• Flood and high-water risks (PPRI).
• Local seismicity, technological risks from the neighbor's factories (PER).
• Radioactive radon, as well as soil toxicity in old urban environments (SIS).

The final form (État des Risques et Pollutions - ERP) must not exceed SIX (6) months in the strictest sense of the term from the date of the officially enacted signature or its addendum.

2. The Asbestos Technical Dossier (DTA) for Workplaces

Warning: Public Health Hazard in Europe! If workers receive a payslip under the structure of the tenant's leased walls and they intervene within a site whose building is based on a Building Permit posted before July 1, 1997, the French health code demands that they have daily, absolute discretion, without right of obstruction, to possess or access the DTA (Dossier Technique Amiante) to study the vital locations: to know whether external removal cladding or the fireproofing flocking in the cellars are releasing micro-asbestos filaments.

The Landlord owes the transmission of the centralized, updated document simply by an indexed PDF email.

3. The Environmental Annex (The "Green Lease")

Very specific to urban environments or Parisian headquarters. If the lease covers a commercial space and office hub that continuously accumulates more than 2,000 (two thousand) Square Meters in a single block, then the "Climate" environmental obligations jump a huge step with a Charter: the "Green Annex or the Energy Pact (Environmental Lease)." An annual exchange is mandated between the occupying tenant to optimize their Carbon consumption, water supply, and computer waste. The lease includes an annex with half a dozen grids for strict quantified annual reviews (Eco Energie tertiary decree).

4. Tertiary DPE and Environmental Code L134-1

Just like in residential housing, the "DPE" (Energy Performance Certificate), known as the DPE with Mention or Activities DPE, has been a marketing obligation from the start. However, its aspect remains informal and indicative. The score of a storefront classified "H" as a climate sieve (very common among butchers or restaurants with multiple thermodynamic extractions and refrigerated airlocks) only states the overall character and non-binding energy surcharge before 2030, compared to the refurbishment and rent freeze of French citizens' homes in comparative law. It has two labels.

5. Transparency on the Heart of Finances: The Pinel Law's "Inventory of Charges"

This mechanism is not "environmental" but the cornerstone of the annexes required by the Commercial Code since 2014 under the era of Minister Sylvia Pinel: No more discreet documents and a tenant who is unaware of their Property Tax cost rebilled to them, a fact they did not know before concluding the lease:

• A Rigorous Inventory of Charges Specifying Their Distribution: For any renewable lease (and any first-time tenant), a listed table of tax distributions with their respective evaluations, rents, and inherent charges must be distributed, as well as various syndicate fees.
• In default: Any obscure modification of a charge imposed "unilaterally as an annual surcharge" that was not declared and inserted in the annex of "Article L145-40-2 in Pinel Law" is strictly non-collectible before a Tribunal.

How Landager Simplifies Commercial Disclosures

Complete portfolio audits all hit a wall against this mountain of complex ecological PDFs, subject to an unstable array of schedules and reissue constraints (Asbestos after works, or the 6 months of the ERP). From the flat modeling in the Commercial Rental Compliance System (SCL) module, Landager prevents "arming to green" a commercial lease ready to be ratified if the table lists an expired anomaly or the absence of the Inventory for its future rebillable Property Tax.
