Does the city have a record of the building plans for each home? We want to know where the gas lines were laid out in our backyard. Can you tell me how to proceed with getting this information?

Please call the general information line for Building and Safety: 805-654-2771

No, generally the city will require a builder to provide plans for a planned development but a custom home might not be available.

I live in Ventura, not LA. Would Ventura have this info?

Try navigate la website for gas line. Also try city of Los Angeles pcis permits online.
