Just curious.. In many houses I've owned I've added electrical outlets
by tapping into the electric that comes into the box where the light
switch is. Usually I put the added electric outlet down by the floor
like most outlets are. Is tapping into the lighting circuit to add
outlets any sort of code violation? The only thing I can think is
that it obviously adds more potential draw to the lighting circuit but
it's still protected by it's breaker so other then the lights going
off if the breaker trips it doesn't matter. Does the code prohibit
mixing lights and outlets on the same circuit or anything? I've had
old houses that actually had a plug as a factory part of the light
fixture over the sink.

AFAIK, there is no code requirement to keep receptacles on a
separate circuit from lights. And Ashton could tap into a
light circuit for an additional outlet. As M pointed out,
if it's being added in an area that now requires, AFCI, GFCI, etc
then those issues are supposed to be dealt with, but
that's a different subject.
Not sure about "current" code, but "normal practice" or "best
practices" a few years ago were lights and outlets "in a given room"
on separate circuits, but lights in one room and outlets in another
room could be on the same circuit.
Been a few years since I worked with my dad, an electrician - and
things DO change.

I think our house built in 1939 was like that, and even as a child I saw
the advantage of having either the desk lamp or the ceiling light still
working when a fuse blew.
Or maybe it was the house built in 1952
Of course they ruined this by not putting ceiling lights in bedrooms

That is a design issue and the NEC says in the introduction that this
is not a design manual, It only addresses safety. 240.4(D) insures
you will trip a breaker before you overload the conductor on "small
conductors". ( 14 & 12 ga) The 80% safety factor is built into the
maximum breaker size (15 & 20a).
Don't know about thew US of A, but here in Canada lights and outlets
on the same circuit are commonplace BUT there is a limit to how many
loads can be on a circuit - can't remember offhand how many - but
regardless of the current draw, only "X" devices per circuit.
Also, tapping into the lighting circuit at the switch is NOT a
recommended practice. Better to daisy chain off an existing outlet -
but even then it is important to know how the circuit is wired.
There is no restriction to the number of outlets, receptacle or
otherwise on 15 and 20a circuits in general lighting areas. General
lighting means just that, the 15 and 20 amp circuits in the dwelling
and they can serve lights and receptacles. That changes a little in
the kitchen or in bathrooms. but I am guessing that is not what we are
talking about. The issue might be whether there is a neutral present.
If so, no sweat. The other issue will be box fill. Usually the boxes
tend to be full already so adding a circuit will overfill them.

a maximum of 12 combined outlets and lights..
Ontario code allows lights, for sure.
Each individual light fixture: counts as 1
Ceiling fans: usually count as 3, 1.5 for lights & 1.5 for fan.
Range hoods: count as 2
General purpose receptacles, hallway, living rooms etc: count as 1
Home theater, computer areas: if its a dedicated area, put it on its
Garages and outside receptacles: don't go more than 2 per cct,
Sumps: Usually by themselves, but do yourself a favor and put 1
regularly used light on with it (hallway,entry etc) that way if it
does trip you'll know sooner rather than wetter.
Kitchens, bedrooms and bathrooms have their own rules which you'd have
