Building square footage, material and construction type, and location are the top cost drivers for prefab self-storage buildings. Other factors, such as customization and specific features (i.e. climate-controlled units, security additions, contactless check-in, interior flex spaces, etc.), also impact the overall cost.
On average, self-storage facilities start at around $17 to $20 per square foot for PEMB materials. Building erection can range from $6 to $10, and the full construction cost (including materials and construction) can range from $110 to $150 PSF for project sizes under 100,000 SF.
