2017 NEC on GFCI replacing 2 prong duplex

[junkhound]

I am not current on 2017 code as work primarily aircraft/spacecraft and ships.
WA state adopted 2017 as of this July 1st.

Our church parsonage needs an upgrade, I'm the likely suspect to do the work.
One simple initial upgrade is replacing 2 prong duplex with GFCI where existing wiring is old romex with no ground wire.

Is this GFCI without ground wire still allowable in 2017 code or does 2017 require pulling new NM or adding conduit?
I'm assuming 2017 code also requires TR GFCI, correct ?

Need to go thru the parsonage for other needed upgrades, but that is the first item I'll probably have code interpretation questions about after I have a chance to go thru the building a few weeks from now. Am guessing I'll need to upgrade a lot of stuff, parsonage built in early 1960s, no idea what WA code cycle was back then.

Don't forget AFCI protection, or Dual Function outlets if existing fuse box wont fit AFCI breakers.

For 2017 outlet replacements 406.4(D)

406.4(D)(2)(C) GFCI protection is required where 3-prong plugs are used without grounding wires, if "marked “GFCI Protected” and “No Equip‐
ment Ground”..

406.4(D)(3) AFCI protection is required where replacements are located in any areas specified in 210.12(A) or (B).

406.4(D)(5) Tamper Resistant (TR) replacements are required as specified else‐where in this Code, except where a non-grounding receptacle is
replaced with another non-grounding receptacle.

. . . parsonage built in early 1960s, no idea what WA code cycle was back then.

The Early Sixties is one of the periods of big basic change in the NEC. The 1962 NEC was the first Code to require that all receptacles installed had to be grounding type. This is when romex with reduced equipment ground wires appeared. The EGC was commonly a #16 solid, sometimes bare, sometimes with a green insulation.

If the romex in the parsonage doesn't have an EGC, then the Code in effect predates the local adoption of the 1962, or there were local amendments that altered the that Code.

With existing nongrounding type receptacles, it sounds like the parsonage was wired under the 1959 NEC.

There is no way to grandfather new plug replacements under the original building code, without adding AFCI & GFCI protection required by the current code cycle.
