Quoth "David Eduardo" in

Local zoning pretty much prohibited us from
having a generator. we were in a landmark building, in an older area. No
fuel tanks allowed.

Are there no natural-gas powered emergency generators?

Seems like a natural application. No tanks needed.

There are gas powered generators, using propane of LNG sources. However, one
fueled from gas lines would not be useful. In major emergencies, gas is shut
off; in LA a major tremor will cause any gas installations made in the 90's
and later to shut off. Since quakes are the main reason you would have a
generator in LA, the gas one would not make sense.
