Municipal grading permits ensure that earth‑moving work doesn’t endanger public safety or water quality. These rules help prevent erosion, uncontrolled runoff and landslides and protect neighboring properties from flooding City of San José | Home.
By requiring site plans, drainage controls and inspections, cities safeguard the environment and your investment. Any cut, fill or re‑contouring that alters established grades may trigger a permit requirement particularly in areas with steep terrain or sensitive watersheds Santa Clara County Planning.
Why Permits Matter
Local governments establish grading ordinances to regulate earthwork, drainage and sediment control. When you regrade your yard, you potentially channel runoff into new paths, which can undermine foundations, clog storm drains and pollute creeks Permit Sonoma.

Key Triggers for a Grading Permit
Volume of Soil Moved
Most jurisdictions require a permit once you move more than a specific volume—often 50 to 150 cubic yards of earth Santa Clara County PlanningContra Costa County. Even small slopes can exceed these thresholds if your yard is large.
Cut or Fill Depth
Excavations or fills deeper than 3 to 5 feet generally trigger engineering review and a permit application Contra Costa CountyMunicode Library. Exemptions may apply if work is under a valid building permit for a foundation.
Slope Steepness
Altering slopes beyond a gentle 3:1 ratio (three horizontal to one vertical) often requires a permit and geotechnical certification to ensure stability California Building Guide.
Proximity to Watercourses

The Review and Inspection Process
Initial Review: Planning staff checks your plans for compliance with grading ordinance thresholds, drainage and erosion controls Santa Clara County Planning.
Engineering Review: If your project exceeds volume or depth limits, a civil engineer ensures slope stability and safe drainage Municode Library.
Field Inspections:
Pre‑grade Inspection: Verifies correct placement of erosion measures before any soil is moved.
Final Inspection: Confirms the site matches approved plans and that vegetation or hardscape stabilizes new grades City of San José | Home.
Common Pitfalls and How to Avoid Them
Under‑estimating Soil Volume
Loose soil occupies more space than in‑place material. Always calculate “bank” vs. “loose” cubic yards California Building Guide.Skipping Early Permits
Starting work without approval can prompt stop‑work orders and costly remediation Contra Costa County.Neglecting Drainage Paths
Rerouting runoff onto a neighbor’s property can lead to liability claims and permit revocation Permit Sonoma.Delaying Inspections
You must schedule inspections at specified milestones—failure to do so voids your permit City of San José | Home.
