Multifamily Apartment Construction in New Mexico

Four units is the line. Under the state's contractor classifications, GB-2 work is limited to residences and apartment houses of not more than four family units, and anything larger moves into the commercial building world governed by the GB-98 General Building classification. That is more than a licensing footnote, since it signals what changes at five units: commercial code, fire protection, accessibility, inspection and a different level of coordination from a builder and its trade partners.

We build apartment communities, garden-style complexes, townhome rows and larger multi-story buildings for developers and owners across New Mexico. Our first job is usually to understand the pro forma, because an apartment project is a financial machine and every design choice has a rent and a cost behind it. We ask about the unit mix, the amenities that will really lift rents, the finishes that will survive tenant turnover and the financing conditions that set the schedule.

Then we turn to the site. Utilities, drainage, access and neighbors can make or break a multifamily project, and the best time to learn about them is before the land closes. We tell owners what we see in plain language and help them adjust the plan so it fits the ground they have.

Where New Mexico housing demand is building

Apartment demand is tied to employment and to land that can be served with utilities. In Los Lunas, the Meta data center employed more than 1,000 construction workers at peak and is projected to support 400 operational jobs once its expansion is complete, which has drawn attention to housing along the Interstate 25 corridor. In Eunice, Urenco's enrichment expansion is expected to support 300 to 600 jobs at peak construction and 70 long-term operations jobs, creating short-term and long-term housing needs in a small town.

On the border, Sunland Park's revised Rancho Santa Teresa annexation proposal covers approximately 362 acres, with the city projecting it would add $50 million to the local economy, and an Albuquerque Journal article ties it to neighborhoods near the Santa Teresa industrial area. Each of these places needs housing in a different form, and we talk with owners about Sunland Park and Eunice as much as about larger metros.

Commercial code, licensing and fire protection

Apartment buildings above the four-unit threshold are designed under the 2021 New Mexico Commercial Building Code (14.7.2 NMAC), which adopts the 2021 International Building Code as amended and took effect July 14, 2023. That code brings requirements for fire-resistance-rated separations between units, sprinklers, accessible units, egress and smoke control. The 2021 Commercial Energy Conservation Code also applies, and its envelope and mechanical requirements shape wall assemblies, windows and heating and cooling systems.

Licensing matters too: the GB-98 General Building classification includes the work authorized by GB-2, GF-5, GF-7 and GS, and covers erecting, altering, repairing or demolishing residential and commercial buildings. We confirm the licensing and permitting path with the owner, the lender and the local building department at the start so that nothing delays the first draw.

Sequencing for lenders and lease-up

Lenders and equity partners watch the schedule closely, and so do the leasing teams. We typically build in phases, completing buildings in a sequence that lets the owner begin leasing while others are still being finished. Site utilities, grading and foundations come first, then framing, rough-ins, drywall and finishes proceed building by building, with clubhouse and amenity spaces timed to open when the first units are ready.

Long-lead items such as electrical gear, windows and elevators drive many schedules. We order them early, track delivery and coordinate field conditions so they can be installed as soon as they arrive. For communities that include structured parking or ground-floor retail, we coordinate with podium-wrap construction methods to keep the schedule realistic. Weather planning is also essential, particularly roofing and exterior finishes during summer storms and winter cold.

Site, utilities and neighbors

The site often has more influence on an apartment project than the building does. Drainage, grading and utility capacity determine where buildings can go and what they cost, and site development and utilities work frequently takes up a large share of the first phase. Fire access and parking counts affect density, and neighbors may raise concerns about height, traffic and views at public hearings.

We talk with the owner about the neighborhood early and help prepare materials for hearings. We also plan construction traffic, noise and dust control with neighbors in mind. In smaller communities, where a new apartment complex may be the largest project in years, being a good neighbor builds goodwill for the owner as well as the builder. We also confirm the availability of skilled trades in the area, since labor shortages can affect schedules and costs.

Apartment types we build

Our multifamily experience covers garden-style apartments, townhome clusters, three- and four-story walk-up buildings, elevator-served mid-rise buildings and mixed-use projects with retail below. Wood framing is the common choice for low- and mid-rise buildings, while taller or podium designs may combine concrete, steel and wood. Each has particular fire-protection, acoustic and structural considerations.

We also build age-targeted and specialty housing, including senior living communities, workforce housing and affordable projects with tax credit financing and compliance reporting. For developers, our multifamily developer work and our multifamily and mixed-use building experience offer a way to benchmark costs and schedules.

Questions Owners Ask

What is the difference between a four-unit building and a five-unit building for construction?

The line matters. Residential-scale work up to four units is covered by a narrower contractor classification, while larger apartment buildings are built under the commercial building code and the General Building classification. Fire separations, sprinklers, accessibility and inspection are all more extensive above four units.

How long does it take to build an apartment community?

A garden-style community may take a year or more depending on size, while larger or multi-story projects take longer. Entitlements, utilities and lender requirements often add time before construction starts. We provide a schedule with phasing so leasing can begin before the whole community is finished.

Can you build affordable or tax credit projects?

Yes. These projects carry compliance reporting, material standards and sometimes prevailing-wage or other requirements that must be built into the schedule and the budget. We ask for the program documents early and set up the reporting process before the work begins.

How do you control costs during construction?

We use detailed estimates, early buyout of major trades, regular cost reports and a clear change-order process. We also hold design reviews to find savings that do not compromise durability, such as standardizing unit layouts and details.

Do you handle site work for apartment communities?

Yes. Grading, utilities, drainage, paving and landscaping are part of our scope when the owner wants one team responsible. Coordinating site and building work reduces gaps and delays.
