Commercial building construction contractors have endured declines. Interest rate hikes plunged business sentiment, decreasing expansion projects and hindering new commercial construction. Also, the transition to remote and hybrid work environments has hampered demand for office building construction, with office rental vacancies reaching a 30-year high in the fourth quarter of 2024. Industry revenue has been declining at a CAGR of 0.2% over the past five years to total an estimated $40.0 billion in 2025, including an estimated gain of 1.5% in 2025 as interest rate cuts begin to encourage new construction. Contractors have managed to expand profit from lows in 2020 but surging wage costs have strained considerable profit growth. Some of the growth for commercial building construction contractors has been price-based because of rising material costs for commercial buildings. This trend has been particularly true with office building construction, which increased as a share of revenue despite square footage under construction being at its lowest point in twenty years in the fourth quarter of 2024. Still, growth in additions and improvements spending, particularly from hotels, restaurants and bars, have buoyed the performance of contractors. Also, new construction in markets like warehouses, indoor recreational buildings and retail and wholesale outlets has provided contractors with avenues for growth. Commercial building construction contractors will enjoy solid growth. Continued rate cuts through 2025 will incentivize new construction. One market that will greatly benefit contractors is new hotel construction. While other markets will improve, office building construction may lag as vacancy rates remain high and 90.0% of active office building construction is set to be complete in 2025. Contractors will struggle to expand profit as labour shortages persist and push up wage costs. Tariffs may hike construction material prices, particularly HVAC equipment, potentially disincentivizing downstream construction expenditures. Also, contractors will have to adapt to some evolving trends, like the increased use of modular construction and changing building codes to improve commercial building sustainability. Modular construction techniques will help contractors combat labour shortages and higher wage costs because they are less labour-intensive. Overall, industry revenue is forecast to expand at a CAGR of 1.9% to total an estimated $44.0 billion through the end of 2030.
