San Diego's reputation for mild weather doesn't extend to East County — El Cajon, Santee, Escondido, and inland construction sites regularly hit 110°F in summer. And the §3395 outdoor threshold of 80°F is crossed at coastal sites too. HeatLog tracks each site by its specific address, so you're documented wherever you work.
HeatLog monitors the weather at each San Diego job site using its exact address — so a coastal Chula Vista site and an inland El Cajon site get independent, accurate readings. When a threshold is crossed, the record is built automatically.
Every morning at 6am, HeatLog checks the NOAA National Weather Service for each of your site addresses — coastal or inland. The temperature used is the one for that specific location, not a county-wide average.
Your supervisor gets an email alert with a one-click compliance checklist: shade, water, cool-down breaks, buddy system. Takes under 60 seconds to confirm.
The confirmed record is saved with a server timestamp that cannot be backdated. Download your full monthly audit log as a PDF and hand it to an inspector on the spot.
San Diego County's building boom, large military contractor base, agricultural East County, and growing logistics infrastructure all create heat compliance obligations — many of which employers don't realize apply to them.
San Diego's residential and commercial construction market is one of California's largest. East County job sites in Santee, Lakeside, and Spring Valley regularly exceed the 95°F high-heat threshold from June through October.
Landscape crews servicing San Diego's residential communities, HOAs, and commercial properties. The 80°F action level is crossed at coastal sites too — not just inland. All outdoor landscape work is covered by §3395.
Avocado, citrus, and ornamental nursery operations in Ramona, Valley Center, Escondido, and other East County areas. Farm workers and nursery staff working outdoors are covered whenever temperatures reach 80°F.
Civilian contractors performing maintenance, construction, and grounds work at San Diego's military installations. Private contractors on federal property are still subject to California law — Cal/OSHA has jurisdiction.
Distribution centers and food warehouses in the Otay Mesa and Kearny Mesa industrial corridors. Loading dock and staging areas that aren't fully climate controlled are subject to §3396 at 82°F.
Rooftop and ground-mount solar installation crews work fully exposed on hot surfaces — rooftops in summer can be 20°F+ hotter than ambient air. This is outdoor work covered by §3395.
The regulations apply whenever the temperature at your work location reaches the threshold — not a regional average. At 80°F, the action level for §3395 kicks in: you must document that water and shade were available. Coastal San Diego frequently hits 80°F from June through September. The key is that HeatLog is site-specific — a Chula Vista crew near the bay and an El Cajon crew 15 miles inland will get independent readings based on their exact addresses. Coastal sites will log fewer triggered days; inland sites will log more. Both are covered when their threshold is actually crossed.
Yes. HeatLog supports both outdoor (§3395: 80°F/95°F) and indoor (§3396: 82°F/87°F) sites under one subscription. When you add a site, you select its type — outdoor or indoor — and the correct thresholds are applied automatically. Each site gets its own weather check, its own alert email, and its own compliance log. Download separate PDF reports per site for each month, or email them directly from the Reports tab.
Inspectors want to see: daily temperature at each work location, documentation that water (1 qt/hr per worker) was available, confirmation that shade was accessible within 2 minutes of request, logged cool-down rest periods on high-heat days (95°F outdoor / 87°F indoor), and evidence the buddy system and emergency response plan were followed. HeatLog captures all of this in a single timestamped PDF you can hand over on the spot — with server-recorded timestamps that cannot be backdated.
