Effective Rules

What should suppliers verify first?

Direct answer: Confirm which product category and rule provisions apply from July 1, 2026, then identify required licences and submissions.

Use the State Fire Marshal’s factory-built housing page for current materials.

Installation Manual

Why must the manual match the delivered unit?

Direct answer: Foundation, anchorage, joining, weather sealing and utilities depend on the actual design and loads. Generic manuals can leave critical site interfaces unresolved.

Installer Scope

Which responsibilities should be written into the order?

Direct answer: Name the licensed installer, foundation provider, crane contractor, utility trades, inspector and party closing transport openings. Define who supplies correction materials.

Completion Record

What should be retained after installation?

Direct answer: Keep delivery condition photos, foundation checks, anchor records, module-joint inspections, utility tests, labels, manuals and authority acceptance. Link every record to the unit identifier.

Factory and site logistics should also be checked against OSHA’s materials-handling resources and the destination’s own safety rules.
