At approximately 1500 hours, I received a photo call and text message from BC Hoover regarding a possible electrical fire. I was advised that the home is secured and that the property owner has been notified. As the Fire Marshal (PREV20), I decided to follow up on this matter on Monday, February 23rd, during my regularly scheduled shift. I arrived at the fire scene at approximately 1530 hours on the 23rd and met with the property owner, and cleared it at approximately 1600 hours. OBSERVATIONS/ACTIONS Upon my arrival, I observed an early 1900’s home with redwood or cedar siding and obvious signs of fire from the exterior Charlie side. I conducted a 360-degree inspection of the building and spoke with to understand the property's status. It appeared to be under construction or undergoing a remodel. INVESTIGATION My investigation actions and findings are based on a scientific examination of the fire's origin and cause. Methodology Summary of Statements (property owner) I received a phone message from staff that had called and wanted to meet me at the property to see what they ( and the contractor) had discovered. had photos and a video to share as well. I contacted and set up a time to meet at 1811 Chorro. While at the fire site, shared that and contractor may have a theory about the cause of the fire. The theory involved the sun and a reflection from the all-seasons room located just underneath the AOO. In a video shot by and the contractor, you can clearly see a large reflective beam coming from the glass/plastic panels on the all-season room. FIRE CAUSE 1. IGNITION SOURCE: Sun reflection off the panels of the all-season room. 2. MATERIAL FIRST IGNITED: Redwood siting, the siting is over 100 years old and shows signs of deterioration. 3. OXIDANT: Oxygen from the surrounding air. 4. EVENT WHICH BROUGHT IGNITION SOURCE AND MATERIAL FIRST IGNITED TOGETHER: It appears that the sun was reflecting off the all-season room, and a large solar light beam was discovered pointing to the AOO. In the photos provided, you can see the large amount of light directed in a particular area. PHOTOS # 9 DIGITAL PHOTOGRAPHS WERE TAKEN AND UPLOADED TO THE ELECTRONIC CASE FOLDER # 1 VIDEOS WERE RECORDED AND UPLOADED TO THE ELECTRONIC CASE FOLDER CONCLUSION Based on the scene examination, physical evidence, and photographic documentation, the fire originated when sunlight reflected off the panels of the all- season room, concentrating a focused beam of solar energy onto the exterior wall at the area of origin (AOO). This concentrated radiant heat ignited the 100-year-old redwood siding, which had significant age-related deterioration and was highly susceptible CLASSIFICATION OF THE CAUSE ACCIDENTAL: Fires caused without direct human intervention or action (2025 NFPA 921 3.3.3) My opinion of the origin and cause of this fire is based on the following: 1. My more than 11 years of professional service in the firefighting industry 2. My more than 7 years of professional full-time fire investigations 3. I have personally conducted and/or assisted in over (300) fire events 4. I have over 250 hours of fire investigation and related law enforcement training Joshua Daniel Fire Marshal 13:40:55 Unit Response Incident Unit Responses Page 4 of 7 Incident Location:1811 CHORRO Incident Date:02/22/2026 Incident City, State, Postal Code:San Luis Obispo, CA 93401 Incident Number:26-01205 Incident Date:02/22/2026 Unit NERIS ID Unit Call Sign Apparatus ID Apparatus Action Unit Dispatch Time Unit Enroute to Scene Time Unit on Scene Time Unit Incident Clear Time Apparatus or Resource In Service Date Time Unit Response Mode FD06079086S007U000 E4 E4 Suppression - Structural Fire Suppression - Interior ; Search Structure - Door Initiated Search - During Suppression 14:29:33 14:49:53 16:14:30 16:14:30 Incident Unit Response Personnel Personnel Name/ID Personnel Rank Or Grade Personnel Role Personnel Level Personnel Time Out Woods, Mitchell Captain 02/22/2026 16:14:30 Johnston, Kenneth Engineer 02/22/2026 16:14:30 McClanahan, Maren Firefighter 02/22/2026 16:14:30 FD06079086S006U006 BC2 BC2 Command and Control - Establish Incident Command 14:27:15 14:28:22 14:30:00 Emergent FD06079086S006U014 T2 T2 Suppression - Structural Fire Suppression - Interior 14:27:15 14:28:26 14:35:08 15:17:32 15:17:32 Incident Unit Response Personnel Personnel Name/ID Personnel Rank Or Grade Personnel Role Personnel Level Personnel Time In Personnel Time Out Personnel Hours Spent Emerson, Luke Firefighter 02/22/2026 14:27:15 02/22/2026 15:17:32 0.84 Child, Robert Captain 02/22/2026 14:27:15 02/22/2026 15:17:32 0.84 Weis, Trevor Engineer 02/22/2026 14:27:15 02/22/2026 15:17:32 0.84 FD06079086S006U016 T1 T1 Ventilation - Vertical - During Suppression 14:27:15 14:30:26 16:06:47 16:35:24 16:35:24 Page 5 of 7 Incident Location:1811 CHORRO Incident Date:02/22/2026 Incident City, State, Postal Code:San Luis Obispo, CA 93401 Fire Location Type:Structure Fire Investigation Needed:Yes Fire Water Supply:Hydrant Greater 500 Fire Investigation Type:Investigated On Scene Resource Fire Arrival Condition:Structure Involved Fire Floor Of Origin:2 Fire Room Of Origin Type:Bedroom Fire Damage Type:Moderate Damage Structure Fire Cause:Unable To Be Determined Smoke Alarm Presence:Not Present Fire Alarm Presence:Not Present Other Alarm Presence:Not Present Incident Number:26-01205 Incident Date:02/22/2026 Unit NERIS ID Unit Call Sign Apparatus ID Apparatus Action Unit Dispatch Time Unit Enroute to Scene Time Unit on Scene Time Unit Incident Clear Time Apparatus or Resource In Service Date Time Unit Response Mode Incident Unit Response Personnel Personnel Name/ID Personnel Rank Or Grade Personnel Role Personnel Level Personnel Time In Personnel Time Out Personnel Hours Spent Barrett, Richard Captain 02/22/2026 14:27:15 02/22/2026 16:35:24 2.14 Van De Walker, Gegi Firefighter 02/22/2026 14:27:15 02/22/2026 16:35:24 2.14 Polkow, Matthew Engineer 02/22/2026 14:27:15 02/22/2026 16:35:24 2.14 Barkhimer, Jake Engineer 02/22/2026 14:27:15 02/22/2026 16:35:24 2.14 FD06079086S008U002 E3 E3 Suppression - Structural Fire Suppression - Interior 14:27:15 14:30:03 14:33:49 16:14:01 16:14:01 Incident Unit Response Personnel Personnel Name/ID Personnel Rank Or Grade Personnel Role Personnel Level Personnel Time In Personnel Time Out Personnel Hours Spent Hicks, Judson Firefighter 02/22/2026 14:27:15 02/22/2026 16:14:01 1.78 Hutslar, Dane Engineer 02/22/2026 14:27:15 02/22/2026 16:14:01 1.78 Witt, James Captain 02/22/2026 14:27:15 02/22/2026 16:14:01 1.78 Fire Details Structure Fire Casualty/Rescue People Involved Risk Reduction Fire Suppression Page 6 of 7 Incident Location:1811 CHORRO Incident Date:02/22/2026 Incident City, State, Postal Code:San Luis Obispo, CA 93401 Fire Suppression Presence:Not Present CSST Ignition Source:No Incident Number:26-01205 Incident Date:02/22/2026 Emerging Hazards Page 7 of 7
