Steven,
Once I have established 'intent to land' I have never had a problem
even at 200'

My home field Concord CA gets plenty of avection fog every summer and the
LDA has a 380' minimum as lowest IFR altitude
I get in SVFR about twice a summer when IFR can't.

By itself, yes. But extended flight under a solid 400' ceiling will
likely require a violation of FAR 91.119
