Anchoring / Anchorage
Methods used to secure a structure against wind and movement.
Applies to
Sheds · Garages · Manufactured buildings · Decks · Roof framing
Project example
A manufactured shed may need an approved ground-anchor layout tied to the model, soil condition, and local wind exposure rather than a generic anchor note.

Where this term shows up in permit work and how it affects the project
Anchoring is the load path between the improvement and its support, so missing product data or spacing can delay structural review and inspection.
If this term appears in a form, plan comment, or local ordinance, start with the building permit guide, compare it against the zoning permit guide, then use the permit guide directory to find the right local path.
Why anchoring / anchorage matters in a permit file
Anchoring connects a building or component to its support so wind, uplift, sliding, overturning, and other loads can travel safely into the ground or primary structure. The correct system depends on the actual product, substrate, geometry, loads, and installation.
Where it appears in the permit process
Load-path design
The design identifies what must resist uplift, shear, overturning, and movement and where those forces transfer.
Product and detail review
Anchor type, size, spacing, embedment, edge distance, corrosion protection, substrate, and connections are documented.
Installation inspection
The AHJ may inspect anchor placement before concrete, concealment, skirting, or finishes prevent verification.
Final verification
Installed anchors, straps, bolts, plates, and manufacturer components are compared with the approved documents.
What you may need
- Structural load path and anchoring plan
- Anchor schedule with size, spacing, embedment, and substrate
- Manufacturer installation instructions and evaluation report when applicable
- Wind, seismic, soil, or structural calculations when required
- Special-inspection or installation records for regulated systems
Where to get it or verify it
- Use the adopted structural criteria and the exact substrate and loads shown in the approved design.
- Get model-specific anchor data and installation instructions from the product manufacturer.
- Use a structural engineer when the system, loads, existing concrete, masonry, soil, or field condition falls outside published prescriptive details.
Common mistakes that create comments or delays
- Submitting a photo of an anchor without capacity or installation data
- Changing the slab, foundation, or building model while keeping the old anchor plan
- Ignoring embedment, edge distance, corrosion, or substrate condition
- Concealing the anchors before inspection
What to do next
- Trace the load from the structure to the supporting soil or primary framing.
- Select an anchor system approved for the real loads and substrate.
- Coordinate layout with foundations, framing, utilities, and openings.
- Document installation and required inspections before concealment.
