NAICS 237210

Overview

The North American Industry Classification System (NAICS) is the framework federal statistical programs use to classify U.S. business establishments for consistent economic data collection and publication. Developed under the Office of Management and Budget and adopted in 1997, NAICS is a cooperative system with Statistics Canada and Mexico’s INEGI; the current U.S. vintage is 2022. ¹
NAICS 237210 Land Subdivision covers establishments primarily engaged in servicing land and subdividing real property into lots for subsequent sale to builders. Servicing may include excavation to install internal roads and utilities, performed directly or via subcontractors. Legal-only subdivisions without land preparation are excluded. This activity typically precedes residential, commercial, or industrial park development. ²

What this NAICS covers

• Subdividing and servicing land parcels to create lots for sale to builders. ²
• Preparing subdivision infrastructure, including grading and excavation for internal roads. ²
• Coordinating installation of utility lines and related basic services within subdivisions. ²
• Managing or subcontracting site work that precedes vertical construction. ²
• Developing residential tracts, commercial subdivisions, or industrial parks prior to building. ²

Frequently asked questions

• What activities are included under NAICS 237210?
  Establishments subdivide and service land—grading, building internal roads, and coordinating utility installation—to create buildable lots for sale to builders. Work may be performed in-house or through subcontractors and typically precedes residential, commercial, or industrial development. ²

• How does NAICS 237210 differ from NAICS 238910 Site Preparation?
  Land Subdivision focuses on creating serviced lots for sale. Site Preparation covers preparing land owned by others for building (e.g., grading, excavation) outside a subdivision context. Subcontracted road and utility work may be classified in other construction NAICS when performed for a subdivider. ²

• Which codes apply when utilities or roads are installed for a subdivision?
  When performed on a subcontract basis for a land subdivider, utility system construction generally falls under NAICS 237110 and road installation under NAICS 237310. The prime land subdivider remains classified in NAICS 237210. ²

• What is the small business size standard for NAICS 237210?
  SBA sets a $34.0 million receipts-based size standard for Land Subdivision. Eligibility for small business set-asides is determined against this standard and the NAICS designated in the solicitation. ³

• When did NAICS move to the 2022 vintage, and why does it matter?
  Census programs began disseminating data on a 2022 NAICS basis with 2022 Economic Census releases; remaining programs transition by 2027. Using the current vintage improves comparability across federal datasets and reflects updated industry definitions. ⁴
