Overview of the Commercial Real Estate Market in 2026
In 2026, the commercial real estate market in France is characterized by contrasting dynamics across segments: offices, retail, and warehouses/logistics. The post-COVID recovery is accompanied by a reorganization of usage patterns, impacting vacancy rates, rent levels, and expected yields. Commercial leases, primarily of the 3/6/9 year type, remain the standard, with rent indexations based on the ILC or ILAT indices, ensuring a certain stability of rental income during inflationary periods. This article details the key trends and investment opportunities for 2026.
3/6/9 Commercial Leases and Rent Indexation
The 3/6/9 year commercial lease remains the standard contractual framework in France for commercial premises and offices. It offers a balance between stability for the lessor and flexibility for the tenant, with a minimum duration of 9 years but the possibility of triennial termination by the tenant (Article L145-4 of the Commercial Code).
Regarding rent indexation, two main indices are used:
ILC (Commercial Rent Index): a composite index integrating the evolution of consumer prices, construction costs, and retail trade turnover. It is predominantly applied to commercial premises and offices, ensuring an average annual indexation around 2.5% in 2023-2025 (INSEE).
ILAT (Tertiary Activities Rent Index): a more specific index for tertiary activities (offices, business premises). It is often preferred for office and warehouse leases, with an average annual evolution of 2.3% over the same period (INSEE).
The recent high inflation (3.2% average annual in 2022 according to INSEE) has reinforced the importance of these indexations to preserve landlords’ purchasing power.
Office Segment: Persistently High Vacancy Post-COVID
The office segment, historically a pillar of commercial real estate, remains under pressure in 2026. The health crisis accelerated remote work and space reorganization, durably impacting demand.
According to the Bank of France, the office vacancy rate in Île-de-France stands at 10.5% at the beginning of 2026, a high level compared to the historical average of 7% over the past decade. This overcapacity is explained by:
Obsolete or poorly adapted spaces for new hybrid work modes.
Excess supply, particularly in peripheral areas.
A slowdown in transactions, with an 8% decrease in leased space in 2025 compared to 2019 (Bloomberg).
Rents show stagnation, or even slight decreases in some neighborhoods, with a weighted average rent around €350/m²/year in Île-de-France (CBRE, 2026). Gross yields in this segment range between 5% and 6.5%, depending on location and building quality.
Retail: Uneven Recovery Across Sectors
The physical retail sector showed strong resilience in 2025, driven by the full reopening of sales outlets and an increase in consumption (+3.1% in 2025, INSEE). However, performance remains highly segmented:
City centers and premium districts: demand for quality retail space remains strong, with rents slightly rising (+1.5% in 2025) and yields around 5.5%.
Peripheral shopping areas: more affected by e-commerce competition, they show vacancy rates close to 9%, with yields up to 7% due to higher rental risks.
3/6/9 leases with ILC indexation ensure annual rent revaluation, essential in an inflationary context.
Warehouses and Logistics: The Big Winner in Commercial Real Estate
The warehouse and logistics segment is the undisputed star of commercial real estate in 2026. The growth of e-commerce, industrial reshoring, and demand for more resilient supply chains explain this dynamic.
Key figures include:
Warehouse vacancy rates are very low, around 3.5% nationally (BNP Paribas Real Estate, 2026).
Average rents increased by +4.2% in 2025, reaching €65/m²/year on the outskirts of major metropolitan areas.
Gross yields are attractive, ranging between 6.5% and 8%, higher than those of offices and retail.
Strong demand is pushing institutional investors to favor this segment, often via specialized REITs (SCPI) or dedicated funds. Indexation on the ILAT guarantees protection against inflation, essential in an uncertain economic environment.

Risks and Opportunities for French Investors
Risks:
Vacancy and obsolescence of offices: investors should prioritize renovated or well-located assets, adapted to new environmental standards and tenants’ flexible needs.
Competition and digitalization: physical retail must adapt to e-commerce, which can impact the profitability of traditional retail spaces.
Inflation and interest rates: if inflation remains high, rising rates could hinder credit access and weigh on valuations.
Opportunities:
Logistics real estate: a fast-growing segment with solid fundamentals, recommended to diversify a portfolio.
Valuation of indexed leases: 3/6/9 leases with ILC/ILAT protect against rent erosion, securing income.
Energy transition: high-performance and sustainable buildings benefit from increased demand and can generate rent premiums.
Conclusion: Where to Invest in 2026?
The commercial real estate market in 2026 presents a differentiated landscape:
Offices: still a fragile segment, requiring rigorous selection, favoring quality, location, and energy renovation. Moderate yields (5-6.5%) reflect the increased vacancy risk.
Retail: opportunities limited to premium locations, with moderate yields (5-7%) and vigilance regarding tenant sustainability.
Warehouses and logistics: clearly the most attractive category, with solid fundamentals, low vacancy, strong demand, and high yields (6.5-8%). This is the recommended segment for French investors seeking to maximize the risk/return profile.
In summary, for a French investor, diversifying the portfolio by including a significant share of logistics assets indexed to ILAT, while maintaining selective exposure to renovated offices and retail in premium areas, constitutes a balanced and resilient strategy in 2026.
