Local code questions behind chimney cap installation
Big ranch-style houses here often carry wide, heavy chimneys built before crickets and seismic reinforcement were standard. A wide stack without a cricket tends to leak on its uphill side, and rebuilding one means adding the steel the current code asks for. We see single-flue brick, shared multi-flue stacks and factory-built chases in this area, and each gets inspected to its own rulebook.
