Overall average office lease size across Miami sees notable year-over-year increase

After three consecutive years of declining average lease sizes from 2022 through 2024, Miami’s office market experienced a notable rebound between 2024 and 2025. Average deal size increased from 3,206 square feet in 2024 to 3,758 square feet in 2025, representing a 14.7% rise across office assets.
This increase was largely driven by Trophy/Class A space, which recorded a 20.5% year-over-year gain, underscoring the continued flight-to-quality trend in the Miami market. Occupiers are increasingly willing to commit to larger footprints in the highly amenitized, well-located assets that deliver a superior workplace experience. In contrast, Class B properties experienced a modest year-over-year decline.
Supported by a healthy office development pipeline and elevated vacancy levels in top-tier assets, the Miami office market is well positioned to continue seeing growth in average lease sizes within Trophy/Class A space and across the broader office market in 2026.
