Drilling holes close to either edge of a joist will weaken it. The holes should be drilled in the middle of the depth of the member. __________________ Answers based on the National Electrical Code.

The only way to fix this would involve adding sister joists to the existing framing. You would also need to remove the cabling to allow the sisters to be installed. __________________ Answers based on the National Electrical Code. Local amendments may apply.
