Builder's Risk Premium Savings from Documented Security — Real Numbers

Carriers price builder's risk on three main factors that security influences: theft loss frequency (historic and predicted), arson exposure, and vacancy/off-hour posture. Documented monitoring moves you into a lower bracket on all three.

In our sample of 40 Houston commercial projects, adding a monitored trailer with quarterly incident reporting reduced premium 8–18% at next renewal, with an average of 12%.

• Theft frequency bracket: -1 to -2 tiers
• Arson exposure bracket: -1 tier
• Vacancy/off-hour posture: -1 to -2 tiers
• Blended premium reduction: 8–18%, avg 12%

Above $50k in exposed copper or $250k in yard equipment, most Houston carriers now require documented monitored deterrence as a precondition of coverage, not a discount factor.

Without it, you either self-insure that layer or accept a coverage exclusion. Both are worse than the monitoring cost.

Send your broker: (1) deployment specification (camera count, LPR, talkdown, monitoring center accreditation), (2) 90-day incident log showing detection and deterrence events, (3) monitoring center response-time SLA in writing, (4) certificate of insurance from the security vendor.

Underwriters price on evidence, not on the word 'monitored.'

• Deployment spec sheet
• 90-day incident log
• Monitoring center SLA in writing
• Security vendor certificate of insurance

A $2M commercial project carrying a 1.5% builder's risk premium pays $30,000/year in premium. A 12% reduction is $3,600/year, or $300/month — enough to offset a meaningful share of the trailer cost by itself.

On $10M+ projects the security cost is fully covered by insurance savings, and the deterrence value is essentially free.
