Helical piles in Auburn, California

Auburn sits in Placer County, where building criteria change with elevation. Placer County's residential design criteria list an 18-inch frost line for elevations of 5,001 to 7,000 feet and 24 inches above 7,000 feet, so a lot in the foothills and a cabin higher in the Sierra Nevada can have different requirements. Confirm the value for your address with the county.

Helical piles suit this kind of ground. The equipment is compact, installation produces little spoil, and crews can work around mature trees and septic systems without large excavations. Typical uses in the state's mountain and hillside areas include decks and additions where concrete trucks cannot reach, foundation repair for settled homes, and mountain cabins.

Costs and what to ask

For a baseline, HomeGuide reports about $2,000 to $4,000 per installed helical pier across the U.S. California jobs often trend higher because of labor costs, engineering and difficult hillside access. See our helical pier cost guide for what a written estimate should include.

Questions to ask any company quoting work in Auburn:

• Engineering: Who is the engineer of record, and have they checked the lot against mapped hazard zones and the county's frost criteria?
• Torque logs: Can I get the final installation torque for each pier in writing?
• Galvanizing and shaft size: What pile diameter, helix configuration and corrosion protection will be used for this slope?
• Permits and warranty: Which Placer County or City of Auburn office issues the permit, and is a geotechnical report required before approval?
