What does Dubai’s new Law No. (3) mean for existing buildings?

Earlier this week, the Government of Dubai announced Law No. (3) of 2026 on Building Quality and Safety, introducing a new regulatory framework to strengthen oversight of construction standards and building performance across the emirate. While the legislation applies to both new and existing developments, its greatest impact may be felt across the thousands of buildings already in operation.

The law forms part of a broader shift toward stronger climate and sustainability regulation across the UAE. In 2024, the federal government introduced Federal Decree-Law No. (11) of 2024 on the Reduction of Climate Change Effects, requiring organisations to measure and report greenhouse gas emissions and develop decarbonisation strategies aligned with the UAE’s Net Zero 2050 pathway.

Together, these policies signal an important evolution in how building performance is regulated. Historically focused on compliance during design and construction, the new law places greater emphasis on operational safety, lifecycle performance, and ongoing asset management. In practice, building owners will increasingly need to demonstrate that their assets remain safe, compliant, and properly maintained throughout their operational life.

Why existing buildings are in focus

This shift is acting as a catalyst in Dubai’s development cycle. 

Around 30% of the city’s buildings were constructed during the early-2000s boom, with another 20% dating back to the 1980s and 1990s. As a result, roughly half of the emirate’s building stock is now 25 to 40 years old, the point at which many mechanical, electrical, and plumbing (MEP) systems begin reaching the end of their operational lifecycle.

For asset owners, this presents both a challenge and an opportunity.

Ageing systems can lead to safety risks, inefficiencies, and rising operating costs, particularly where maintenance has not kept pace. At the same time, these buildings offer significant potential for targeted upgrades and strategic retrofits that enhance performance, resilience, and long-term asset value.

What the new law means for asset owners

Although detailed implementation guidance is still emerging, the intent is clear. Asset owners and operators will need a more structured understanding of the condition, compliance status, and future performance of their buildings.

In practice, this is likely to drive increased demand for technical transparency related to services such as:

• Building condition assessments
• MEP compliance and safety audits
• Asset lifecycle and capital planning reports  
• Retrofit feasibility studies
• Pre-transaction technical due diligence

These assessments provide the technical foundation needed to prioritise upgrades, manage risk, and plan capital investment over the remaining life of an asset.

The growing risk of inaction

For many asset owners, the greater risk may be assuming that existing buildings will remain compliant indefinitely. Ageing MEP systems, undocumented modifications, and evolving safety standards can gradually create gaps between a building’s original design intent and its current operational condition.

As regulatory oversight strengthens, these gaps may become increasingly visible. Owners who proactively assess and address these issues will be far better positioned to manage risk, plan capital investment, and protect long-term asset value.

The opportunity for smarter upgrades

For many buildings, the solution will not be wholesale replacement but targeted modernisation of core building services.

At Cundall, our building services teams work at the intersection of life safety, system performance, and long-term asset value. Through technical due diligence, retrofit strategy, and MEP modernisation programmes, we support owners in understanding the true condition of their assets and identifying practical pathways to improve safety, efficiency, and resilience.

The transformation of Al Maryah Tower provides a compelling example. Once at risk of becoming a stranded asset, the building underwent one of the region’s most significant retrofit programmes, including a full HVAC system overhaul, upgraded fresh-air infrastructure, and major improvements to core building services and life-safety systems.

The project now serves as a scalable model for how ageing buildings across the UAE can be revitalised to extend their lifespan while contributing to the country’s broader net-zero ambitions.

Looking ahead

As Dubai’s building stock continues to mature, proactive asset management, targeted retrofits, and robust building services strategies will become increasingly critical.

For owners and operators, the priority will be clear: understand the true condition of existing assets, invest strategically in upgrades, and ensure buildings remain safe, efficient, and compliant for the decades ahead.

Law No. (3) reinforces a clear shift in regulatory thinking. Building performance is no longer assessed only at completion, but across the entire operational lifecycle of the asset.
