Being Historic, and having been permitted under the 2001 CHBC, I read under 8-402.2 One-Hour Construction "Upgrading an existing qualified historic building or property to one-hour fire-resistive construction shall not be required regardless of constrcution or occupancy when one of the following is provided:
1. Sprinklers (I might consider this, but expensive, especially for a commercial install with standpipes, etc., not to mention how ugly that is. If the Fire Marshall was willing to allow the home and office/retail portion to both be residential grade, then it makes more sense...any thoughts on this?)
2. An approved life-safety evaluation.
3. Other alternative measures are approved by the enforcing agency.
So what exactly are the possibilities regarding #2 and #3? What does this mean? Can anyone provide examples for these measures or evaluations?
