What’s the Average Utility Cost in Boise, Idaho? 2025 Guide from a Local Agent

As a Boise real estate agent with years of experience crunching budgets for Treasure Valley buyers—from cozy North End bungalows to spacious Meridian family homes—I’m often hit with: "What’s the average utility cost in Boise, Idaho?” As of November 2025, it’s a budget-friendly $285/month for a typical 1,800 sq ft household (3-4 people, moderate usage), spanning electricity, natural gas, water, sewer, and trash. That’s 15% below the national average of $336, fueled by Idaho’s hydro-heavy grid and efficient local providers. With recent rate tweaks and seasonal swings, let’s break down Boise utility costs 2025, neighborhood variances, and hacks to shave 10-20% off your bill while linking to today’s hot housing market.

2025 Boise Utility Breakdown: Monthly Averages by Service
Based on November 2025 data from Idaho Power, Avista, City of Boise, and resident surveys, here’s what a standard home pays (excluding internet at $70 extra):
- Electricity (Idaho Power): $110 (900 kWh at 11.62¢/kWh)—up slightly from summer dips but 30% under U.S. $147 average. Recent 10% residential rate cut in April 2025 keeps it low; expect a $5-12 bump in 2026.
- Natural Gas (Avista): $55 (level pay for 66 therms)—steady year-round, but winter peaks hit $85 (Jan-Feb). Post-9.2% hike in Sept 2025, it’s still 20% below national; 2026 holds flat.
- Water (City of Boise/Veolia): $35 base (winter average; summers +$50 for irrigation)—tied to usage, with rebates for low-flow upgrades. Stable into 2026 at 1-3% inflation.
- Sewer (City of Boise Water Renewal): $32 (usage-based on winter water; 9.9% FY2026 increase from Oct 1 adds ~$3/month)—bundled billing every two months keeps it predictable.
- Trash/Recycling/Compost (City of Boise/Republic Services): $23 flat (8.4% residential hike Oct 2025 to $260/year)—includes weekly trash, bi-weekly recycling, compost, and bulky pickups. EV fleet upgrades drive the rise, but 95% satisfaction holds.

Grand total: $255 core utilities (add $30 for seasonal peaks). Apartments average $150; larger Eagle homes hit $350. Level pay evens out spikes.
