I can't answer the question, though I suspect that as a homeowner you could make the change and it's very unlikely that anyone would ever ding you on it. Even a home inspector for a buyer isn't likely to know the lights aren't original.

Others with real CA experience will know much more about this, however.

One caution - be aware of the considerable heat output from some xenon pucks. I've seen chocolate chips melt in the bag when stored in cabinets above xenon lamps.

You can put in any lighting you want if you're not getting it inspected.

Something along the lines of "If no one knows, you can get away with it". The problem is making sure no one ever finds out.

That is a decision you need to make.

All remodels are subject to title 24.

It is always best practice to pull a permit from your local city/county before performing any work.
It will create value to your home and also be safe from fires
