Modular locker system: $300-1,500 per locker. Metal cages: $200-600 per cage. Secure room: $3-15k per room buildout. Amortize 15-25 years. Monthly rent 5-15× amortized monthly cost = strong ROI. Example: $500 locker amortized $2.50/mo over 15 yr rents at $45/mo = 18× monthly ROI.
Demand dynamics?
Urban multifamily: 70-95% of units have no in-unit storage = huge demand for add'l. 60-85% adoption when available. Suburban: 40-60% adoption (more in-unit space). Modern Class A: storage often included in rent (luxury feature). Class B/C: paid add-on. Waitlists common at mature buildings.
Revenue impact?
200-unit building with 100 storage lockers at $40/mo × 80% occupancy = $38.4k/year. Cost: ~$2-5k amortization + $1-3k operational. Net: $30-35k/year. Scale across portfolio: 10 buildings = $300-350k/year storage revenue. Material ancillary revenue for sophisticated operators.
