Plumbing Requirements for Kitchen Remodels

Common requirements

• Proper trap and venting for a relocated sink, including island sinks that need a code-approved vent method
• Dishwasher drain connection with an air gap or high loop as required
• Gas range connection, shutoff and a gas test if piping changes
• Water hammer and supply sizing for added fixtures like pot fillers

Permits

Moving the sink or adding gas piping needs a plumbing permit. Replacing a faucet in place usually does not.
