Retaining walls 4 feet tall or higher require a separate building permit and plan review. A separate building permit is still needed even if retaining walls were shown on the civil construction plans. See the Retaining Wall Plan Review Checklist for a list of information to submit with your construction drawings for plan review.

You should also contact PUPS to request that any underground utilities are located before you start digging. Visit their website at www.sc811.com for more information.  If any utility lines are found, there may be utility easements or rights-of-way present on your property. These should be shown on a survey of your property. You can also contact our office to verify if any rights-of-way are present.
