Commercial leasing in the UAE is now guided by Federal Decree-Law No. 25 of 2025, which abrogated Federal Law No. 5 of 1985 (Civil Transactions Law). This new federal law, along with local tenancy laws in individual Emirates (such as Dubai Law No. 26 of 2007 as amended by Law No. 33 of 2008, and Abu Dhabi Law No. 20 of 2006), continues to allow for broad "freedom of contract" in commercial leases, enabling parties to define maintenance obligations contractually. This means sophisticated corporate landlords can legally shift almost all maintenance burdens onto the tenant, diverging from default residential protections.
The Blank Canvas of the Commercial Addendum
The standard Unified Contract generated by Ejari (Dubai) or Tawtheeq (Abu Dhabi) contains very little detail regarding complex building maintenance. The true allocation of maintenance responsibilities in UAE commercial real estate is primarily determined by the Commercial Addendum—the customized legal document attached to the registered lease.
If a commercial lease lacks a detailed Addendum allocating maintenance, the relevant tribunal (such as Dubai's Rental Dispute Settlement Centre (RDSC) or Abu Dhabi's Rental Dispute Settlement Committee) will likely revert to general civil law principles under Federal Decree-Law No. 25 of 2025 (similar to the principles previously found in Article 767 of the abrogated Civil Transactions Law). These principles generally stipulate that the landlord is responsible for major structural repairs and any defects affecting the tenant's intended use and enjoyment of the property, while the tenant is responsible for minor or routine maintenance and repairs not attributable to the landlord's fault.
Common Commercial Lease Structures in the UAE
Experienced landlords primarily utilize two leasing structures, defined clearly in their addendums:
1. The Standard "Gross Lease" (Office Towers & Shopping Malls)
Commonly used when leasing individual floors in an office tower or a single retail unit inside a large shopping mall.
- Landlord Responsibilities: The landlord (or the Building Management/Owners Association) is responsible for the exterior of the building, the roof, the structural foundations, and all "Common Areas" (elevators, lobbies, communal bathrooms, security, exterior lighting).
- Tenant Responsibilities: The corporate tenant maintains only their specific, leased interior space. They repair their own interior lighting, fix their own sinks, and maintain the hygiene within their designated square footage.
- The Threshold Clause: Similar to residential leases, the Addendum will assign a financial threshold (e.g., "The Tenant handles all repairs under 2,000 AED per occurrence").
2. The Commercial "Triple Net" / "NNN" Lease (Standalone Assets & Warehouses)
Commonly utilized when leasing a standalone industrial warehouse, a factory site, or an entire, single-occupant corporate building.
- Total Tenant Responsibility: The commercial landlord negotiates an Addendum that pushes the absolute burden of operating the asset onto the tenant's company.
- The Three Nets: The tenant agrees to pay a base "net" rent to the landlord, and separately assumes full, 100% financial responsibility for:
- N - Paying all municipal property taxes, DED fees, and utility bills.
- N - Securing and paying for comprehensive property insurance protecting the structure.
- N - Handling ALL maintenance, repairs, and capital replacement costs, including structural roof repairs, replacing dead central HVAC compressors, and repaving parking lots.
In an NNN lease scenario, the landlord simply collects rent and is insulated from the sudden, massive capital expenses of building ownership. The UAE RDSC fully supports and upholds NNN clauses, provided they are explicitly and unambiguously written and signed by the corporate tenant's authorized signatory.
Civil Defense and Safety Compliance
A critical aspect of UAE commercial maintenance is municipal safety compliance.
- The commercial Addendum must explicitly state who is responsible for maintaining the Fire Alarms, Sprinkler Systems, and obtaining the annual Civil Defense Certificate necessary for the tenant to renew their Trade License.
- In NNN leases, this complex logistical and financial burden is placed entirely on the corporate tenant. In Gross leases within malls or towers, the landlord usually manages overarching Civil Defense compliance while charging the tenant a "Service Charge" to cover the communal costs.
