Site constraints such as limited access or hillside construction can significantly increase time and equipment use.
| Trigger | Impact | Typical Range | Notes |
|---|---|---|---|
| Garage conversion or openings | Increases framing and loads | $8,000–$25,000 | Structural rework required |
| Additional shear walls | Higher material and labor | $10,000–$40,000 | Most common driver |
| Limited site access | Longer work hours | $5,000–$20,000 | Special equipment needed |
