Tips: Fire-Resistant Home Construction in Coastal California - Part 2

Cost of Fire-Resistant Construction

Investment Analysis: Standard vs. Fire-Resistant Building Methods

Every project is different, and the site conditions can affect the cost of construction greatly (for example, building on sand in Malibu will be more expensive than building on a flat piece of property with stable soils). The following is meant only as a generic example to illustrate how implementing fire-resistant construction can increase the cost of construction. Also, please note that I am using the descriptor of “upscale” construction, loosely based on the quality level of materials as described in the “2024 Cost vs. Value Report” which can be downloaded at costvsvalue.com. The finish materials described in this report for “upscale” projects aligns with the minimum level of finishes commonly expected in neighborhoods such as the Pacific Palisades. Luxury-level choices will result in higher prices.

Construction Cost Comparison

Standard “Upscale” Construction (Meeting Minimum Los Angeles Building Code):

  • Base cost: $800-1,000 per square foot

  • Basic fire-resistant features required by code

  • “Upscale” finishes but traditional wooden frame construction

  • Standard “upscale” windows and doors, such as metal-clad wood windows

  • Basic roofing materials

  • Standard ventilation systems

  • Code-minimum fire protection

Enhanced Fire-Resistant “Upscale” Construction:

  • Base cost: $1,000-1,300 per square foot

  • Additional cost increase: 25-35%

  • Key upgrades:

    • Premium cement fiber or natural stone siding: $45,000-60,000

    • Custom fire-rated windows with enhanced views: $75,000-100,000

    • Premium metal roof system: $90,000-120,000

    • Enhanced ventilation systems: $25,000-35,000

    • Fire-resistant landscaping with “upscale” design: $50,000-75,000

    • Comprehensive sprinkler system: $65,000-85,000

      • Includes:

        • High-pressure pump system

        • Backup power supply

        • Smart monitoring system

        • Exterior sprinkler coverage

        • Water storage tank (5,000-10,000 gallons)
