What GRS Group does

GRS Group (legal name Global Realty Services Group) is a US-based commercial real estate transaction services firm founded in 2006, headquartered in Irvine, California (300 Spectrum Center Dr, Suite 145). The company historically served institutional real estate investors, occupiers, and lenders worldwide through a bundled or individual-service model covering environmental site assessments (Phase I ESA, Phase II site characterization, transaction screens, SBA risk assessments, remediation project management), facilities assessments (Property Condition Assessment, Seismic Risk Assessment, Property Acquisition Assessment, Green Building assessments), GSE lender services for Fannie Mae DUS Lenders and Freddie Mac Seller/Servicers, ASHRAE energy audits, construction advisory (pre-construction plan and cost analysis, progress monitoring, completion assessment), ALTA/NSPS land title surveys, and commercial zoning reports. Its core product was branded GRS | Corteq, with delivery orchestrated through the proprietary Global Services Connection platform and a client-facing portal (GRS Vault) for order management, document access, and transaction tracking.

The business operates as a professional services firm on a quote-based engagement model with no publicly disclosed pricing. Go-to-market is enterprise field sales targeting lenders, buyers, and investors before closing to mitigate environmental, physical, title, and zoning risk. The firm markets itself as pre-approved by Fannie Mae for the Green Rewards program and by Freddie Mac for Green Up and Green Up Plus programs, and as a member of the American Land Title Association producing ALTA/NSPS-standard surveys. Senior leadership averages 20 years of construction management experience, supported by licensed engineers, registered architects, construction experts, and cost analysts. Headcount is in the 51-100 range per firmographics.

In 2020, GRS Group was acquired by NV5, a publicly held professional services firm focused on infrastructure, built assets, and the environment. The company's website now displays "GRS Group Is Now NV5" with a redirect to NV5's site, and GRS operates as a brand within NV5's portfolio. The GRS Group team has evaluated and advised on over $1 trillion in cumulative CRE transactions across its offices in the United States and global affiliates.

• NV5 Global: NV5 is the parent company that acquired GRS Group in 2020, integrating its CRE transaction services into NV5's broader infrastructure, environmental, and geospatial services platform — making it the structural peer for benchmarking the GRS franchise post-acquisition.
• JLL (Jones Lang LaSalle): JLL is a global commercial real estate services platform whose Capital Markets and Advisory businesses compete with GRS by bundling due diligence within broader investment-sales and capital-markets engagements with institutional clients.
• Terracon Consultants: Terracon is a large, full-service environmental and geotechnical engineering firm with a substantial CRE due-diligence practice. It competes with GRS on Phase I/II ESAs and property condition assessments but as part of a much broader infrastructure-services portfolio.
• Cushman & Wakefield: Cushman & Wakefield's Valuation & Advisory and Capital Markets practices include CRE transaction due diligence that competes with GRS's bundled offering, though the firm operates across a far broader service mix.
