Overview
What Is an Annual Maintenance Program?
Last updated: May 8, 2026
Regulatory information on this page is provided for general guidance and may not reflect the most current requirements. Always verify specific deadlines, fees, and compliance procedures with CAL FIRE (fire.ca.gov), San Bernardino County Fire Protection District, or your local fire authority before making compliance decisions.
An annual maintenance program is a recurring service contract that keeps a property in continuous defensible space compliance throughout the year. It is typically structured as 2–4 visits annually, timed to match California fire code requirements, the local growing season, and pre-fire-season prep.
Annual programs are generally the most cost-effective way to stay compliant. They lock in scheduling during peak demand, reduce per-visit pricing compared to one-off jobs, and produce the recurring documentation increasingly required by California insurance carriers under the CDI Safer from Wildfires standards.

Triggers
When do you need annual wildfire defense maintenance?
Properties in Very High Fire Hazard Severity Zones face year-round PRC 4291 obligations.
If you got a 30-day notice last spring, you'll likely get one again this spring without a maintenance plan.
Carriers increasingly require annual proof of mitigation work to keep coverage in force.
Pre-scheduled visits ensure the work is done before the dangerous July–November window.
Scope
What's included in annual wildfire defense maintenance?
- Spring abatement visit ahead of County notice deadlines
- Mid-season maintenance to address regrowth
- Fall cleanup for dead vegetation and Santa Ana season prep
- Recurring brush and weed clearance
- Ongoing tree maintenance and ladder fuel control
- Annual compliance documentation for insurance
- Priority scheduling during peak demand
- Optional Zone 0 inspection and touch-up
Pricing
How much does annual wildfire defense maintenance cost in San Bernardino County?
Annual maintenance contracts are typically structured at preferred rates compared to per-job pricing — generally a 15–25% discount versus the equivalent individual services. Specific rates depend on property size, vegetation profile, and visit frequency. Vetted contractors provide free estimates with itemized scope and visit schedule.
| Plan Tier | Visits Per Year | Typical Cost | Best For |
|---|---|---|---|
| Annual Compliance | 1 visit | $500 – $1,500 | Properties with low vegetation pressure |
| Bi-Annual Maintenance | 2 visits (spring + fall) | $800 – $2,500 | Standard residential |
| Quarterly Maintenance | 4 visits | $1,500 – $5,000 | Heavy vegetation properties |
| Custom Schedule | Variable | Per assessment | Acreage, mountain properties |
Ranges reflect industry-standard estimates. Specific pricing depends on lot size, vegetation density, and access.
Process
How does the annual wildfire defense maintenance process work?
Call or submit the form. A vetted local contractor reaches out to understand your property, your timeline, and any active notices.
A licensed contractor walks the property, documents compliance gaps against CAL FIRE and County code, and provides a written estimate at no cost.
Crews complete the scoped work — clearing, hardening, hauling — to meet PRC 4291 and San Bernardino County Code 23.0301–23.0319 requirements.
You receive written documentation suitable for CAL FIRE reinspection, County abatement files, and California insurance carrier renewals.
