Q1 2026

Boise Commercial Real Estate Market Report

Focus: Q1 2026 Market Trends

Executive Summary

The Boise commercial real estate (CRE) market in Q1 2026 is defined by resilient demand, tightening vacancies in key sectors, and massive regional economic catalysts. The Office sector is demonstrating steady improvement, characterized by low supply-side risk and a continued flight to high-quality space. Industrial fundamentals have rebounded sharply following a soft start to the previous year, driven by major infrastructural and corporate expansions, including Micron's $15 billion fabrication facility. Retail remains highly stable, with overall vacancy holding flat at near-historic lows despite mild year-over-year adjustments. In the Multifamily sector, Boise is a national standout; after a period of elevated deliveries, the market led the nation in vacancy compression as robust demand rapidly absorbed the excess supply.

TenantBase Proprietary Data highlights the distribution of active tenant demand over the last 90 days:

  • Retail/Storefront dominated market activity with 56.00% of all searches.
  • Office was the second most active sector at 25.33%.
  • Warehouse accounted for 18.67% of total search volume.

Office Market

Market Overview Office fundamentals in the Boise metro demonstrated resilience and modest improvement heading into 2026, driven by steady demand and strong underlying economic drivers.

  • Vacancy & Absorption: The overall vacancy rate ticked up slightly to 7.7%, but impressively remained 140 basis points below prior-year levels, underscoring highly competitive market conditions. Most submarkets recorded vacancy declines, with only the Bench, Caldwell, and Downtown posting annual increases.
  • Demand Drivers: Tenant demand remains heavily concentrated on modern, high-quality Class A space.
  • Supply Constraints: Supply-side pressures are minimal, with recent construction volume tracking at just 243,581 square feet across five projects. With inventory projected to expand by just 1.3% in 2026, the market faces incredibly limited near-term oversupply risk.

TenantBase Activity

  • Demand Share: Office accounted for 25.33% of total search volume.
  • Lease Term Preference: Tenant demand leans heavily toward short-term flexibility, with Less than one year capturing 47.37% of searches, followed by an even split between 2-3 Years and 3-5 Years (each at 21.05%).
  • Size Requirements: Requirement footprints scale dramatically with longer term lengths. The average lower-bound requirement for a 5+ Year lease is 35,000 SF, which is roughly 4,100% larger than the 833 SF required for short-term (<1 year) leases.

Industrial & Warehouse Market

Market Overview Boise's industrial market finished the previous year strong, positioning the metro for sustained momentum in 2026 supported by a growing population and strategic infrastructure improvements like the Highway 16 expansion.

  • Vacancy & Absorption: While the industrial vacancy rate climbed to 9.1% due to a steady influx of speculative supply, occupier demand rebounded massively in the latest quarter. Net absorption surged to approximately 644,000 square feet at year-end, a sharp increase that reversed a sluggish start to the previous year.
  • Leasing Drivers: Boise's emergence as a regional hub is heavily supported by major investments like Micron's expansion. Absorption is expected to remain strong, particularly in well-located, mid- to large-sized facilities.

TenantBase Activity

  • Demand Share: Warehouse space captured 18.67% of total search volume.
  • Lease Term Preference: Industrial tenants display a highly balanced approach to lease terms. Less than one year, 1-2 Years, and 3-5 Years each captured an equal 25.00% share of active searches.
  • Size Requirements: Mid-term industrial requirements necessitate substantially larger footprints. The average lower-bound space requirement for 3-5 Year terms is 27,875 SF, which is approximately 178.75% larger than the average requirement for 1-2 Year terms (10,000 SF).

Retail Market

Market Overview The Boise retail market continues to operate with healthy fundamentals, maintaining tight availability despite broader macroeconomic shifts.

  • Vacancy & Availability: The overall retail vacancy rate remained flat quarter-over-quarter at a tight 4.2%, though it climbed 100 basis points year-over-year.

TenantBase Activity

  • Demand Share: Retail/Storefront activity dominated the Boise market with 56.00% of all search volume.
  • Lease Term Preference: Retailers prioritize operational stability, with mid-term commitments leading demand. 2-3 Years and 3-5 Years each captured 26.09% of all active deals.
  • Top Locations: Locational interest was heavily concentrated in the primary metro corridors, with Meridian capturing the highest share of interest (12 deals combined), followed by Eagle (5 deals), Boise (3 deals), and Caldwell (3 deals).

Multifamily Market

Market Overview The Boise multifamily market is achieving equilibrium at a remarkable pace, driven by powerful demographic and employment tailwinds.

  • Vacancy Compression: Boise recently led the entire nation in multifamily recovery, posting a massive 350-basis-point year-over-year decline in vacancy. As construction activity receded, robust demand successfully absorbed the excess vacancy, moving market conditions much closer to equilibrium.
  • Supply & Occupancy: Overall occupancy settled at a strong 94.3%. Construction activity has continued to wind down, with just 597 units remaining under construction heading into 2026.
  • Economic Catalysts: Micron's $15 billion semiconductor fabrication facility in Boise is projected to generate more than 15,000 new jobs, providing an exceptional long-term demand catalyst for the regional housing market.

2026 Outlook

Moving further into 2026, the Boise CRE market is strongly positioned for balanced growth and tightening availability.

  • Office Tightening: Tightening availability combined with steady demand and an incredibly small construction pipeline will position the office market for continued momentum and increased landlord pricing power.
  • Industrial Momentum: As developers actively acquire land in anticipation of future growth, the industrial sector will continue to thrive on the back of regional infrastructure upgrades and manufacturing expansion.
  • Multifamily Stabilization: With the construction pipeline thinning out and massive job-creating projects underway, Boise's apartment fundamentals are expected to fully stabilize, allowing for renewed rent growth throughout 2026.
