Commercial build-out timelines: what sets the finish date

The calendar in our job trailer runs backward. It starts with the day the owner needs to open and works toward the first day of demolition. When an owner asks how long a commercial build-out takes, that is the honest way to answer: it takes the time between those two dates, and the question is whether the work fits. Most of the time it does, if the pieces that move the date are handled early.

Count from opening day backward

Working backward from opening day sets the order of everything else. A retail tenant with a lease commencement date, a dental practice with patients already booked, a hotel with rooms sold on the reopening date: each has a fixed end, and the schedule is built to protect it. From that date we subtract the closeout weeks, then the finishes, then rough-in and inspections, then demolition and framing, and the remainder is the time available for permitting and procurement before a crew can start. If that remainder is negative, we know on day one and can talk about what changes.

The shell decides your starting line

A first-generation shell, bare concrete and a demising wall, needs everything: framing, full MEP rough-in, ceilings, finishes, a restroom that meets the fixture count. A second-generation space, one built out by a prior tenant, may keep its ceiling grid, its restrooms and its HVAC, or it may need to be gutted because the layout is wrong. A quick walk with the drawings in hand tells us which. Second-generation space is faster only when the old layout resembles the new one; otherwise demolition adds time the owner did not expect.

Permits and the weeks you do not control

Every jurisdiction reviews on its own clock. Houston, Austin, Dallas, San Antonio and each of their suburbs run different processes, and a reviewer's comment letter can add a cycle. We cannot make a city move faster, but we can submit a complete set the first time, answer comments the day they arrive, and use the review weeks to order materials and line up crews so that construction begins the morning the permit is issued instead of the week after.

Long-lead items and owner decisions

The items that most often set the finish date are not walls or paint. They are rooftop HVAC units, electrical switchgear, storefront glass, custom millwork, commercial kitchen hoods, and specialty lighting. Some of these carry lead times measured in months. The first thing we do after contract is write the long-lead list, release the orders, and build the rest of the schedule around the delivery dates. Framing, drywall, paint and millwork we can pace with our own crews; a switchgear delivery we can only order early.

A build-out schedule carries a hidden column: the dates by which the owner must choose tile, confirm the paint color, approve the millwork shop drawings, sign the change order. When those decisions come late, the trade waiting on them idles, and the trades behind it stack up. We give owners a decision calendar alongside the construction schedule so the two run together, and the principal running the job calls when a date is approaching rather than after it has passed.

The last three weeks are their own project

Substantial completion is not opening. After the last coat of paint come the final inspections, the fire alarm test, the certificate of occupancy, FF&E delivery, the punch walk and the punch closeout. Those weeks are where a build-out most often slides, because they involve the most outside parties in the least time. We treat them as a separate schedule, with the inspections booked ahead, our FF&E crew staged for delivery day, and a principal of our company on site walking the punch with the owner.

So how long does a build-out take. A simple retail or office space in a cooperative shell can move from permit to opening in a few months; a restaurant or medical suite in a first-generation shell takes longer, and the permit and long-lead windows in front of construction are often as long as the construction itself. Send over your drawings and the date you need to open, and we will build the calendar backward from it and tell you whether it fits.
