Commercial Tenant Improvement / Alteration Permit in Las Cruces, New Mexico

Required for alterations, remodels, and tenant improvements (TI) within existing commercial buildings in Las Cruces. This is a genuinely distinct track from new commercial construction in the City's own fee schedule: the Fee Table's scope-modifier table lists 'Alteration/TI/Remodel' at 50% of value (versus 100% for New), with the footnote 'See International Existing Building Code definition of work area for guidance in how to calculate alteration work areas,' and the Fire Systems fee section carries separate, lower 'Tenant Improvement Fire Sprinkler' tiers. The application, review agencies, timeline tiers, and ProjectDox submittal process are shared with the general commercial track (the City's Commercial Construction Process guide covers 'Commercial New, Alteration, Addition' together), but a TI's valuation — and therefore its fee — is computed at half the ICC square-foot value of the work area.

When you need this permit

  • Building permit required for commercial alterations, remodels, and tenant improvements; electrical, mechanical, and plumbing sub-contractor permits are required when associated with the general permit
  • Valuation for fee purposes is calculated using the City's Valuation Table (February 2020 ICC Building Valuation Data) at the 50% Alteration/TI/Remodel scope modifier and the 88% local area modifier, applied to the work area as defined by the International Existing Building Code
  • Pre-submittal review meeting required if the project valuation is $1 million or more (the requirement covers Commercial New, Alteration, and Addition alike); optional below $1 million
  • Apply through the City of Las Cruces Citizen Portal (Accela), then upload drawings via ProjectDox as single-page landscape PDFs named per sheet label
  • Reviewed concurrently by the same eleven agencies as new commercial construction: Building, Plumbing & Mechanical, Electrical, Planning, Landscaping, Engineering Services, Environmental Compliance, Flood, Traffic, Fire, and Utilities
  • If the tenant space's use classification changes, a Change of Occupancy analysis is triggered ($45.00 without inspection / $100.00 with inspection), creditable toward the Building Permit Fee if the permit application and issuance occur within 90 days
  • Modifications to an existing fire sprinkler system are permitted through the Fire Prevention Division under the dedicated Tenant Improvement Fire Sprinkler fee tiers (starting at $120.00 for 1-15 heads)
  • A separate demolition permit is required for any work involving plumbing or electrical demolition; interior non-load-bearing demolition is $50.00 standalone or $0.00 when part of the building permit

Inspection process

  1. 1

    Rough / Cover-Up (Frame and Trade Rough-Ins)

    Framing and rough electrical, plumbing, and mechanical in the work area before concealment — the City's fee schedule lists a Cover-up Fee for work concealed without inspection. Inspections are requested through the Citizen Portal after permit issuance (no same-day requests; up to 5 working days out). The City publishes inspection request categories (Building, Electrical, Mechanical, Plumbing) rather than a formal TI-sequence checklist, so this sequence reflects standard practice under those categories.

  2. 2

    Trade Finals (Electrical, Plumbing, Mechanical, Fire)

    Final inspections on each associated trade sub-permit, plus fire sprinkler/alarm acceptance testing where systems were modified

  3. 3

    Building Final / Certificate of Occupancy

    All work complete per approved plans; Same Day Certificate of Occupancy available for $150.00 if all inspections are completed and logged by 12 pm (CO issued by 5 pm)

Tips

  • The 50% Alteration/TI/Remodel scope modifier cuts your fee valuation in half relative to new construction for the same square footage — calculate the work area per the International Existing Building Code definition, as the fee schedule directs.
  • If your tenant's use classification differs from the previous occupant's, request the Change of Occupancy analysis ($45-$100) first — it is credited toward the building permit fee if you apply and are issued within 90 days.
  • Commercial trade sub-permits are flat-fee ($300 mechanical, $300 plumbing) and commercial electrical is amp-based, so small TIs are not penalized by valuation on the trade side.
  • Sprinklered spaces: head relocations and additions in a TI use the dedicated (cheaper) Tenant Improvement Fire Sprinkler fee tiers through Fire Prevention, starting at $120 for 1-15 heads.
  • Interior non-load-bearing demolition is free when included in the building permit ($0.00) but $50.00 as a standalone permit — and any plumbing or electrical demolition requires its own demolition permit.
  • All fees are tripled on work started or completed without an approved permit.

Las Cruces, New Mexico has adopted: New Mexico is a statewide-minimum-code state under the Construction Industries Licensing Act (NMSA 1978 § 60-13-44(E)): 'All political subdivisions of the state are subject to the provisions of codes adopted and approved under the Construction Industries Licensing Act. Such codes constitute a minimum requirement for the codes of political subdivisions.' A county or municipality may become its own code-enforcement authority (operate independently of the state Construction Industries Division field offices) if it employs a certified building official and has adopted at least the current state minimum code standards (NMSA 1978 § 60-13-41(D)-(F)). The City of Las Cruces operates its own Building and Development Services / Community Development Department with its own building official and inspection staff (rather than routing permits through the state CID field office model used in unincorporated areas), enforcing the state-adopted codes as the applicable minimum within city limits.; 2021 New Mexico Commercial & Residential Building Code (based on the 2021 IBC / 2021 IRC), per NM Construction Industries Division (CID) current adoption; 2021 International Building Code (IBC), as adopted/amended by CID; 2021 International Residential Code (IRC), as adopted/amended by CID; 2021 New Mexico Energy Conservation Code (based on the International Energy Conservation Code, IECC) — addresses the New Mexico climate zone for energy conservation; applies to new and renovated residential and commercial buildings; 2021 New Mexico Plumbing and Mechanical Code, incorporating the 2021 Uniform Mechanical Code (IAPMO) and 2021 Uniform Plumbing Code (IAPMO); 2020 New Mexico Electrical Code / 2020 National Electrical Code (NEC), adopted by reference at 14.10.4 NMAC, effective March 28, 2023 (permits issued only under this rule after September 28, 2023) — this is the current, in-force edition; it supersedes any references to a 2023 NEC edition found on third-party aggregator sites; 2012 Solar Energy Code (IAPMO), as adopted by CID; 2017 ICC/ANSI A117.1 (Accessible and Usable Buildings and Facilities), as adopted by CID; 2012 Uniform Swimming Pool, Spa and Hot Tub Code, as adopted by CID; Las Cruces Land Development Code, Chapter 30 (Buildings and Building Regulations) and Chapter 38 (Zoning) — local building-permit administration, fee schedule, and zoning provisions. Local amendments apply — see the Las Cruces overview page for the full list.

The application process, review agencies, and timeline tiers are the same, but the fee treatment is distinct: the City's fee schedule values Alteration/TI/Remodel work at 50% of the ICC square-foot value of the work area (versus 100% for new construction), computed per the International Existing Building Code's definition of work area, and the Fire Systems fee section has separate, lower tenant-improvement sprinkler tiers.
