### Topic: Moisture Mapping

Moisture mapping is a critical process in construction, particularly for wood framing, to ensure the longevity and structural integrity of a building. It involves measuring and documenting the moisture content of wood members to identify areas with excessive moisture that could lead to decay, mold growth, or other problems.

### Acceptable Moisture Levels

The acceptable moisture level in wood framing varies depending on the species of wood used and the intended use of the structure. However, as a general guideline, the moisture content should not exceed 19% for interior framing and 15% for exterior framing.

### What is an Acceptable Moisture Level in Wood Framing?

Excessive moisture in wood framing can compromise its structural integrity, leading to rot, decay, and pest infestation. To prevent these issues, the moisture content should be controlled within acceptable levels.

The table below provides recommended moisture content levels for various wood species and applications:

| Wood Species | Interior Framing | Exterior Framing |
|—|—|—|
| Douglas Fir | 15-19% | 12-15% |
| Southern Pine | 15-19% | 12-15% |
| Spruce-Pine-Fir | 15-19% | 12-15% |
| Hemlock-Fir | 15-19% | 12-15% |
| Redwood | 12-15% | 10-12% |
| Cedar | 12-15% | 10-12% |

It’s important to note that these are general guidelines and specific moisture content requirements may vary depending on the building code and local climate conditions.
