Residents give Mason & Main a D grade (about 3.2 out of 5) from 100+ reviews. Mason & Main offers modern apartments with good amenities and responsive maintenance staff, but residents report significant challenges with management responsiveness, safety concerns in the surrounding neighborhood, high fees (particularly parking and utilities), and inconsistent service quality after move-in. The property experiences recurring issues including fire alarms, package theft, and security vulnerabilities, while leasing staff are often described as helpful during application but less accessible afterward.
Mason & Main offers modern apartments with good amenities and responsive maintenance staff, but residents report significant challenges with management responsiveness, safety concerns in the surrounding neighborhood, high fees (particularly parking and utilities), and inconsistent service quality after move-in. The property experiences recurring issues including fire alarms, package theft, and security vulnerabilities, while leasing staff are often described as helpful during application but less accessible afterward.
Management responsiveness is inconsistent and highly dependent on lease stage. Staff are notably attentive during the application and move-in process, but communication and responsiveness decline significantly after lease signing. Billing issues, including disputed charges and deposit disputes, are frequently reported and often require escalation or legal action to resolve. Maintenance staff receive consistent praise for speed and professionalism, though office staff professionalism varies widely.
Amenities at this property include a gym, roof deck, game rooms, and coffee stations, though many residents report inconsistent functionality and limited access hours (typically closing at 10-11 PM). Parking is a major concern, with costs ranging from $300-$450 monthly for small spaces, frequent vehicle break-ins despite paid security, and limited guest parking. Package delivery systems and common area maintenance have experienced recurring failures lasting weeks to months, including broken entry doors, non-functional package lockers, and poorly maintained trash areas. Laundry facilities experienced extended outages, though maintenance responded quickly when operational.
Mason & Main experiences significant building quality challenges that dominate resident feedback. Recurring issues include noise disturbances from neighboring units and common areas, frequent elevator outages and malfunctions, cleanliness problems in hallways and common spaces, and deteriorating finishes and amenities. While maintenance response times are noted as generally prompt by some residents, the cumulative effect of these physical condition issues, combined with security and neighborhood concerns, has led many residents to relocate.
The property offers convenient transit access to downtown and light rail, with proximity to shopping and dining. However, the neighborhood presents significant safety concerns including frequent incidents and visible drug activity. Parking is expensive ($300-400/month) with limited availability and security issues including vehicle break-ins. Management responsiveness and communication are inconsistent, with residents reporting delayed or absent responses to maintenance and safety concerns.
Maintenance response times are generally fast, with most work orders completed same-day or within 24 hours. However, some residents report extended delays on certain repairs, particularly security doors and amenity equipment that have remained broken for months. Communication gaps exist: some maintenance requests go unaddressed despite being reported multiple times, while other residents consistently receive responsive service. Overall maintenance quality is inconsistent across different issue types and time periods.
Mason & Main is very walkable, transit is excellent, and biking is very bikeable.
