Menifee, CA

Grading in Menifee is regulated under MMC Title 7 Article 6 (Subdivision Grading Standards) and California Building Code Appendix J, both administered by the city Engineering Division. A grading permit is required for cuts/fills over 50 cubic yards, slopes steeper than 5 feet, or any work in an easement or floodplain. Drainage must be directed via positive slope away from foundations (minimum 2% for paved, 5% for landscaped) and discharged to an approved outlet — never onto adjoining property.

Menifee FAQ
Do I need a permit to level my backyard?
If you move less than 50 cubic yards of earth and the cut/fill is under 5 feet deep on flat ground (not on a slope steeper than 5H:1V), no grading permit is required — but you still cannot discharge drainage onto neighbors and you may need a building permit if retaining walls are over 4 feet.
Can I drain water onto my neighbor's lot?
No. CBC J109 prohibits discharging surface water across a property line in concentrated form without a recorded drainage easement. Doing so creates civil liability and is a code violation.
Who approves the soils report?
Menifee's Engineering Division reviews geotechnical reports for grading permits. Reports must be prepared by a Geotechnical Engineer or Engineering Geologist licensed in California and stamped per CBC §1803.
