That contrast—higher total absorption with fewer square meters per tenant—has a structural origin. In six years, the tenant base nearly tripled, and the market shifted from a large-footprint model to one that prioritizes efficiency and cost. Today, even corporates are absorbed into modules, and that fragmentation distributes volume among more players. The result is a more diversified and resilient market.

Although the market moves in the same direction, demand does not behave the same across all segments. Since 2019, net absorption per tenant in Class A+ buildings has fallen at a compound annual rate of 14%, compared with 7% in Class A and 9% in Class B.

While the variations show greater adjustment in higher-quality space (A+), what matters is not necessarily the level but the pattern. While Class A+ and A buildings tend to move in parallel—when absorption rises in one, it rises in the other, and when it falls, both decline—Class B operates in the opposite direction: it gains traction when the others lose it and gives ground when they expand.

This dynamic shows that each segment plays a distinct role within the cycle. Class A+ and A buildings capture corporate expansion and consolidation; they are the market’s leading edge and concentrate flight-to-quality and right-sizing strategies when decision-making is aggressive and capital bets on quality and location. Class B buildings operate at the other end of the spectrum: they absorb reconfiguration, downsizing, rotation and defensive demand, acting as the piece that cushions the cycle and keeps the system in balance.

The pattern not only describes recent behavior; it also helps anticipate the likely direction of the next stage of the cycle. Historically, after adjustments in the A+ and A segments, absorption tends to reconcentrate at the top of the market. But that transition is not automatic or guaranteed: it depends on corporate appetite, financing costs and the performance of premium corridors, factors that have defined the leadership of these segments when the cycle regains momentum.

From here, this segmented behavior connects with the cycle’s most decisive variable: the market continues to absorb more space than it delivers. And that relationship between new inventory, gross absorption and net absorption explains the continued decline in vacancy and confirms that the cycle is in a phase of reorganization.

¹ Data reflects only the first nine months of each year, as it is the most recent and comparable information available. The sample includes the country’s main markets: Mexico City Metropolitan Area, Guadalajara, Monterrey and Querétaro. Net absorption was calculated only with identified tenants and excludes records with negative or zero net absorption. Net absorption is used to avoid distortions associated with lateral moves: when a tenant releases and occupies equivalent space, or rotates without increasing its real footprint. This allows measurement of effective expansion rather than reconfiguration.
