The Maronites have St Sharbel's "Mission" (altho it looks pretty permanent) at 10325 Rancho Destino Rd. They've been there since at least January 2008 per the address on the mission's bulletins.
That sounds about right; I was there as the KofC honor guard when their bishop dedicated it (which was actually held in the hall, rather than the much smaller [a triple-wide prefab] church).
As I understand, the property was acquired and church built to effectively force the bishop's hand and get a priest sent.
There had been a previous Maronite priest present, who worked for the RC diocese, with disastrous results (I'll leave the details out; they're readily findable elsewhere).
Anyway, the hall is a large, permanent building they built, of a size adequate to a RC congregation (presumably it will be rented out for events to help pay mortgages).
The church is a triple-wide prefab with small areas to either side of the alters. I'm not sure if they're chapels or icon areas (no separate altars).
Both are rather permanent installations, and they have a full time priest assigned to them. I am baffled by the continued use of "mission," but everything they have, including, iirc, the front of the church, says, "St. Sharbel Mission."
In the 2008 Official Catholic Directory (which would be 2007 info), they were at 2550 E Desert Inn Rd.
That's a strip mall, which includes a Post Box place.
