Grading Permit

A permit required before excavating, filling, or otherwise altering the natural topography of a site, ensuring that earthwork complies with engineering standards and environmental regulations.

What is a Grading Permit?

A grading permit is a construction authorization required before performing significant earthwork on a property — including excavation, filling, grading, and site preparation. The permit ensures that proposed earthwork complies with engineering standards for slope stability, drainage, erosion control, and geotechnical safety. Grading permits are separate from building permits and are often required before the building permit is issued.

When Grading Permits Are Required

Most jurisdictions require grading permits when earthwork exceeds certain volume or depth thresholds, when work occurs on slopes above specified gradients, or when grading could affect drainage patterns, adjacent properties, or protected environmental features. Minor grading associated with standard building construction may be exempt or covered under the building permit.

Grading Permit Requirements

Grading permit applications typically require: a grading plan prepared by a licensed civil engineer, geotechnical (soils) reports, hydrology and drainage studies, erosion control plans, a SWPPP (for sites over one acre), and environmental clearances. The plan review evaluates cut and fill quantities, slope stability, retaining wall design, drainage facilities, and haul route plans for exporting or importing soil.

Grading and Project Sequencing

Grading is often the first physical work on a construction site. For large projects, obtaining the grading permit early — potentially before the building permit is issued — allows site preparation to begin while building plans are still under review. This sequencing strategy can save significant time on projects with extensive earthwork.
