Tenant improvement timelines in El Paso: what actually drives the calendar

A property manager in central El Paso calls with a clean ask. A tenant signed a lease for an 8,000 square foot office suite, they want to be moved in by the first of the quarter, and that gives the build-out about ten weeks. The space is empty. The drawings look simple. Why would a ten-week tenant improvement be a problem?

It usually is not the framing or the paint. Those parts move fast. Tenant improvement schedules slip on the things nobody can see on the floor plan: the permit sitting in review, the rooftop air conditioning unit that takes four months to ship, the landlord who needs two weeks to approve a change. If you know what actually drives the calendar, you can plan a realistic move-in date instead of a hopeful one.

The front end is longer than the build

Owners tend to picture a tenant improvement as the weeks of visible construction. In reality the front end, design and permitting, often takes as long as or longer than the work itself, and it happens before anyone shows up with tools.

A typical El Paso office or retail build-out breaks down roughly like this:

• Design and construction documents: two to six weeks, longer if the space needs an architect and engineered mechanical, electrical, and plumbing drawings.
• Permitting and plan review: three to eight weeks through the City of El Paso, depending on the review queue and how complete the submittal is.
• Construction: eight to sixteen weeks for a standard suite, more for restaurants, medical, or anything with heavy mechanical and electrical scope.

Add it up and a build that feels like a ten-week job is realistically a four to five month project from lease signing to occupancy. The construction phase is the part everyone watches, but it is rarely the part that decides the finish date.

Permitting is a queue, not a switch

The single most common surprise in El Paso tenant improvements is permit timing. A commercial permit is not granted the day you apply. It goes into the City of El Paso review queue and gets routed to building, electrical, mechanical, plumbing, and sometimes fire and zoning reviewers.

Two things move that timeline. First, the city's workload. When commercial activity is heavy across the Borderplex, reviews back up and three weeks becomes six. Second, the quality of the submittal. Plans that are complete, code-compliant, and clearly drawn sail through. Plans with missing details get kicked back for corrections, and every round of comments adds days or weeks.

If the project changes the use of a space, say a retail bay becoming a restaurant, it can trigger a new certificate of occupancy, additional code requirements for occupancy load, restrooms, and exiting, and a longer review. The fix is to get the permit set right the first time. A contractor who has been through El Paso plan review knows what the reviewers will flag and heads it off before submittal.

Long-lead mechanical and electrical gear sets the finish date

Here is the driver that catches the most owners off guard. The framing, drywall, and finishes can be ready, and the project still cannot finish because a single piece of equipment has not arrived.

In 2026 the usual long-lead items on an El Paso tenant improvement are:

• Rooftop air conditioning units: roughly eight to twenty weeks depending on size and tonnage. In a city where summer runs well over 100 degrees, you cannot occupy a space without working cooling.
• Electrical switchgear and distribution panels: twelve to thirty weeks for larger or specialized gear.
• Transformers and new service equipment: often the longest pole in the tent when the suite needs more power than the base building provides.
• Custom storefront, specialty glass, and certain light fixtures: several weeks and easy to forget until late.

The lesson is to order this equipment as early as possible, sometimes before the permit is even issued, so the lead time runs in parallel with everything else. A good preconstruction process identifies the long-lead items in the first week and gets them on order, rather than discovering at week six that the rooftop unit will not land until well after the promised move-in.

Landlord approvals are a real line on the schedule

On a leased space the tenant is not the only decision-maker. The landlord or property owner usually has to approve the plans, the contractor, the insurance, and any change that touches the building structure, roof, or shared systems.

Each of those approvals takes time, and they tend to stack. A change order that affects the roof might need landlord sign-off before work proceeds, and if the landlord is an out-of-town investment group, that sign-off can take a week or two on its own. The way to keep this from stalling the job is to map out who approves what at the start, build those review windows into the schedule, and keep the landlord copied on decisions so nothing waits on a signature nobody asked for.

Inspections are gates, and they come in order

Construction in El Paso passes through a sequence of city inspections, and each one is a gate. You cannot cover a wall until the rough-in inspection passes, which means framing, electrical, plumbing, and mechanical rough-ins all have to be inspected before insulation and drywall go up.

A failed inspection is not just a redo. It is a re-inspection, which means getting back in the city's queue. Scheduling inspections tightly, having the work genuinely ready, and not asking an inspector to look at something half-finished is how a contractor keeps the job from losing days at every gate. The final certificate of occupancy inspection is the one that lets the tenant legally move in, so it sits at the very end and cannot be rushed.

Occupied-building work has to be phased

Plenty of El Paso tenant improvements happen in buildings that never close. A medical office renovating two exam rooms while the rest of the clinic sees patients. A retail center reworking one bay while the neighbors stay open. Occupied work is doable, but it changes the math.

The work has to be phased so that occupants keep safe access and exits, fire alarm and sprinkler coverage stays continuous, and the loud, dusty, or disruptive tasks happen after hours or behind sealed temporary partitions. Demolition and concrete cutting often move to nights or weekends. Dust control and air separation become real line items, especially for medical spaces.

All of that is the right way to keep a business running through a build, but it adds time and cost compared to working in an empty shell. The mistake is treating an occupied-building schedule like a vacant-shell schedule. Phasing should be planned and priced up front so the move-in date reflects reality.

How to protect your move-in date

If you take one thing from this, let it be the sequence. The build is rarely the bottleneck. Get the design done, get a clean permit set in front of the city early, order the long-lead mechanical and electrical gear the moment scope is set, line up landlord approvals before they block you, and plan inspections and phasing into the calendar from day one. Do those things and a tenant improvement lands on time. Skip them and the framing crew ends up standing around waiting on a permit or a rooftop unit.
