Common Area Maintenance are the expenses for operating the "common" areas of the building or property. In a multiple tenant building, there are areas of that property each tenant shares, such as parking lots, common bathrooms, lobbies, grounds, roof, etc. Those areas incur expenses to operate. The lobby may be heated or air conditioned, cleaned and repaired. The parking lot may need resurfacing occasionally. The landscaping needs maintenance. The building may even employ security for the benefit of all tenants. Those expenses are usually passed on to the tenant for their proportionate share, meaning if you rent 1000 sf of a 10,000 sf building, you will pay 10% of the total common area expenses for the building.
