FAQ
Self-Storage questions
- Can I choose different unit sizes?
- Yes. Share your unit mix and door layout so the building framing and openings support it. Interior unit partitions, security systems, and climate-control equipment must be separately specified.
- What do I need for a building quote?
- Provide your building width, length, height, project ZIP code, intended use, and major openings. The engineered package includes anchor bolt plans and foundation reactions for your concrete contractor.
