To construct a new 212 square foot sunroom/solarium addition to an existing 1,705 square foot single family dwelling. This addition will occur over an existing rear patio and will be unconditioned. All work per the approved plans, attached plan review report, and other reviewing agencies approvals. The Building Official has determined carbon monoxide poisoning, smoke and fire related hazards to be specific hazards associated with buildings and/or structures without smoke and carbon monoxide detection and alarm systems that do not meet current building codes. Carbon monoxide poisoning, smoke and fire related hazards are substantial hazards because the likelihood of death and or injury from said hazards increases in buildings and/or structures. The existing portions of buildings or structures with non-existent or inadequate smoke and carbon monoxide detection and alarm systems that do not meet current building codes must be retrofitted to meet current code requirements. **SRZ**
