Some larger airliners must get ground control permission before starting their engines.

1. Is this based on size? Does a Learjet need permission?

2. Is this just turbines? For example does a DC3 or DC6 need permission?

3. How would a pilot find out? Does the airport supplement or some other document show when it is required?

4. Are there exceptions such as jets parked on remote ramps, not at gates, non-commercial?

I know from flying small recips that I never needed permission anywhere in the US or Canada - but certain airliners did.

This airport in Australia says they enforces their right for the engine start. Part of the authorization comes from environmental noise control. townsvilleairport (Australia).

Van Nuy - US, "All aircraft with engines capable of producing more than 14,750 lbs. of thrust must be pushed back or towed onto the taxiway prior to engine start." (Airport ops) (Of course you need ground approval prior to entering a taxi way...)

When working at Anchorage International, Alaska with Continental 737-757, we had to contact ground control. We could start the engines at the gate while doing maintenance; there were no ground crew around. We started the onboard APU, turned on the red strobes, got permission from ground, then started the engines. I never read a document, this info was relayed to me by my supervisors.

3. Is this all controlled airports or does the airport supplement or some other document show when it is required?

This document says the airport has and enforces their right for the engine start. Part of the authorization comes from environmental noise control. But I know from flying small recips that I never needed permission anywhere in the US or Canada - but certain airliners did.  townsvilleairport (Australia).

US is similar. Van Nuy, "All aircraft with engines capable of producing more than 14,750 lbs. of thrust must be pushed back or towed onto the taxiway prior to engine start." (Airport ops) (Of course you need ground approval prior to entering a taxi way...)
