Commercial Construction and Tenant Improvements in McClellan Park

Commercial construction and tenant improvement work in McClellan Park comes with a wrinkle most Sacramento contractors never have to think about: a huge share of the available commercial stock here started life as Air Force base infrastructure. Converting a former hangar, warehouse, or administrative building into modern office, retail, or light-industrial space means working around steel-truss spans and utility routing that were never designed with today’s tenant layouts in mind. TDI Builders has been handling that kind of conversion and ground-up commercial work across the region since 1985.

Why McClellan Park Properties See Unique Buildout Challenges

McClellan Park is an unincorporated redevelopment area in Sacramento County, built on the footprint of the decommissioned McClellan Air Force Base. That history shapes almost every commercial project we take on there. Many buildings have oversized clear-span bays, high ceilings, and heavy-gauge structural steel that was sized for aircraft maintenance, not for a suite of private offices or a retail buildout. Mechanical, electrical, and plumbing systems in these structures are often decades old and were routed for industrial use, which means a tenant improvement project frequently starts with an infrastructure assessment before a single partition wall goes up. Sacramento County handles permitting and inspections for the area, and change-of-use permits are common here because so much of the available space is being repurposed from its original military function into commercial or industrial tenancy.

Our Commercial Construction and Tenant Improvements Process in McClellan Park

We start every project with a walkthrough that focuses as much on what’s hidden as what’s visible: slab condition, existing structural steel, HVAC capacity, and electrical panel load, since repurposed base buildings don’t always have documentation that matches current conditions. From there we build a scope that covers demo, framing, MEP coordination, and finish work, sequenced so tenants with lease deadlines aren’t waiting on permitting delays they didn’t anticipate. Because so much of McClellan Park’s commercial stock falls under change-of-use review, we coordinate directly with Sacramento County on permitting and inspections rather than assuming a straightforward tenant improvement permit will apply. Crews are scheduled to keep active businesses operating where possible, and we close out with a punch list walkthrough before handing the space back to the tenant or property manager.

Reaching McClellan Park from Sacramento

McClellan Park sits just off Watt Avenue near the I-80 corridor, a quick run from our Sacramento base. That proximity matters for commercial projects, where a general contractor needs to be on-site regularly for inspections, subcontractor coordination, and owner walkthroughs, not just for the initial estimate. We keep crews and project managers moving between Sacramento proper and the business park throughout a job rather than treating it as a one-time site visit.

McClellan Park Permitting and Code Coordination

Because the area is unincorporated, commercial permitting runs through Sacramento County rather than a city building department, and the county’s review of a change-of-use application for a former base building tends to look closely at occupancy classification, fire separation, and ADA accessibility upgrades. We handle that coordination as part of the project rather than leaving it to the property owner to navigate separately, which keeps tenant improvement timelines from stalling in plan check. For landlords working with multiple incoming tenants, we also track which upgrades are shell-building responsibilities versus tenant scope, so costs and permit applications land with the right party.

Local note

A detail that surprises a lot of tenants moving into McClellan Park: several of the converted hangar and warehouse buildings still have their original riveted steel roof trusses exposed above the ceiling line. When a tenant improvement calls for new ductwork, sprinkler heads, or suspended ceiling grids, that structural steel often needs a licensed structural engineer to sign off on attachment points before our crews can proceed, which is a step most office buildouts elsewhere in Sacramento never have to budget time or cost for.
