Subject: When does 97 UBC go into effect
About a month ago, I called the Oakland Building Department,
and they told me that it could be as early as June 1, 1999. Is the date
applicable to all CA Building Departments, or do the individual Building
Departments determine the date?
Remember also that the 1997 UBC is applicable in California
only to permit applications filed after June 30, 1999. Permits filed before
that date can use the 1994 UBC which could result in lower design forces.
