- Norman requires plans for manufactured steel buildings to be sealed by an Oklahoma engineer (Norman one and two family residential checklist).
How a shop project usually goes
- Measure your lot and find its zoning, since lot size sets the allowed footprint and wall height in most metro cities.
- Decide on use: parking, workshop, RV storage or ag. That sets door sizes and height.
- Get written quotes that say whether the slab, delivery, anchors and doors are included.
- Pull the permit before anything is delivered.
