Do You Need a Grading Permit in Sacramento County?

Almost every excavation conversation includes the same question: do I need a permit? In the Sacramento region the honest answer is that it depends on where your property sits, what you are doing and how much ground is involved. This article explains how to find out, what agencies usually care about and how to avoid delays.

We are not a permitting agency and nothing here replaces what your jurisdiction tells you. Permit requirements vary by city and county, so confirm with the agency that covers your parcel before work starts.

Why “Sacramento County” is not one answer

Sacramento County has several incorporated cities, including Sacramento, Elk Grove, Folsom, Rancho Cordova, Citrus Heights and Galt. Each city generally handles its own grading and building permits inside its limits. Unincorporated areas fall under the county. Neighboring places such as Roseville, Rocklin and Lincoln are in Placer County, West Sacramento and Davis are in Yolo County, and El Dorado Hills and Placerville are in El Dorado County.

So the first step is simple: confirm which jurisdiction your address belongs to. A mailing address with a city name does not always match the legal jurisdiction, especially near boundaries.

What grading permits are meant to control

Without quoting specific thresholds, which change and vary by agency, grading rules usually aim to protect a few things:

• Drainage. Changing grades can send water onto a neighbor, into a street or toward a building. Agencies want to see that runoff is managed.
• Erosion and stormwater. Disturbed soil can wash into storm drains. Rules often call for erosion control measures, especially during the wet season, roughly November to April.
• Floodplains. In levee-protected areas and FEMA flood zones, fill and grading can be restricted or require extra review.
• Slopes and stability. Cuts, fills and retaining structures on slopes can need engineering.
• Protected resources. Some undeveloped Placer County parcels have vernal pools or wetlands, and trees and other resources may be regulated.

Work that often involves permits

Different jurisdictions treat these differently, but you should ask about permits before starting any of the following:

• Building pads for new homes, additions or accessory dwelling units
• Large regrading of a lot or acreage
• Retaining walls and cut or fill slopes
• Foundation and basement excavation
• Septic systems, which usually involve the county environmental health agency
• Work in or near drainage channels, creeks or floodplains

Smaller jobs such as a limited yard leveling may be treated differently, but do not assume. A short call to the permit counter is cheaper than a stop-work notice.

How to find out what applies to you

1. Confirm jurisdiction. Use the city or county parcel lookup, or call the planning or building department.
2. Describe the work plainly. Give the address, what you plan to change, approximate area and depth, and whether you are importing or exporting soil.
3. Ask specific questions. Is a grading permit needed? Are plans or engineering required? Are there erosion control requirements? Does a flood zone or other overlay apply?
4. Ask about timelines. Plan review time can be the longest part of the schedule.
5. Get answers in writing or note who you spoke with and when.

If a builder, designer or engineer is already on your project, they often handle the application. Confirm who is responsible for what so nothing falls through.

What to prepare

Agencies usually want a site plan showing existing and proposed conditions, property lines and the work area. Larger or more complex jobs may need an engineered grading plan, a soils report or drainage calculations. Having a survey or plot plan makes the conversation faster. If you are not sure what you need, start with the permit counter and ask what a complete application looks like.

Utilities come first, permit or not

California law requires contacting USA North 811 before digging, at least two working days ahead. This applies whether or not your project needs a grading permit. Read Call 811 before you dig in California for the basics. Marked utilities can also change where a pad, trench or driveway can go, which is good to know before plans are finalized.

Timing and the wet season

Permit timing and weather interact. Approval might arrive just as the rains start, and erosion control requirements are tighter in wet months. If your project is large, think about schedule early. A realistic plan accounts for plan review, utility locating, mobilization and weather days.

Common mistakes to avoid

• Assuming a neighbor’s project tells you what your parcel needs
• Starting earthwork before approvals are issued
• Skipping the 811 call because the area “looks clear”
• Importing fill without checking floodplain or drainage rules
• Treating a verbal answer as final without a note or confirmation

When a project changes mid-stream

Plans change. A pad moves, a driveway gets longer, or you decide to import fill after approval. Tell the agency before you do it, because a permit usually covers the work as approved, and changes may need a revised plan. Keep copies of approved plans on site, and make sure everyone doing the work has the current set.
