An empty suite still needs a schedule: a full make-ready when the last tenant or the build-out leaves, a light recurring touch so dust, insects and a stale restroom never greet a prospect, a check before each tour, and one named person who runs the water and watches the air between visits.
That’s the standard a building should be held to. If you’d rather have it in writing, tell us about the space — we walk it and come back with a scope of work and a price, usually within one business day.
Why an empty suite is a Houston question
Your vacant suite has a lot of company. Cushman & Wakefield’s MarketBeat report on the Houston office market, dated July 16, 2026, put overall vacancy at 24.7% for the second quarter of 2026. When close to a quarter of a market’s office space sits empty, a prospect has other suites to compare yours with, and the comparison runs on what they can see: the glass, the floors, the restroom, the air when the door opens.
Our commercial landlord page puts the cost bluntly: “A vacant suite does not lease itself: dusty storefront glass and a stale restroom cost you showings, and every dark month is rent you never recover.” A Downtown tower floor, a suite in Galleria–Uptown, a low-rise in Westchase or the Energy Corridor: the job is the same. Between tenants, the space has to look cared for.
The make-ready: one clean that resets the suite
Every vacancy starts with a reset. After a move-out, you are cleaning up after a tenant’s whole stay: marked glass, dusty sills, a restroom that saw daily use. Our landlord page lists the job as “Vacant-suite make-readies: full clean, storefront glass, and restrooms ready to show”, next to “Move-out turnover cleans coordinated with your leasing calendar”.
After a build-out, or once a spec suite is finished, the problem is construction dust, and that is a different clean. Our post-construction page for Houston explains why it matters to a leasing team: “Fine dust is invisible in person and obvious on camera. This is the pass that fixes that.” It also draws the debris line: “Bulk debris and anything requiring a dumpster stays the contractor’s haul-away”. So the order runs trades out, debris hauled, final clean, then listing photos and tours, because “A punch-list walkthrough goes better when the surfaces are actually finished, not just built.” Furniture the last tenant left behind is a haul, not a clean, and it goes first.
What goes stale in an empty Houston suite, and who fixes it
A dark suite does not stay the way the make-ready left it. Some of what goes wrong is cleaning work and some is not, so put a name next to each line:
- Glass and sills. Dust keeps settling with nobody around, and the glass at the suite entry is the first surface a prospect sees up close. Assign it to: the cleaning visit.
- Insects. Closed rooms collect them on sills and in light lenses. Removing them is cleaning; a steady supply of new ones is a pest-control call. Assign it to: the cleaning visit, then a pest-control vendor.
- The restroom’s water. EPA’s indoor-air design tools for schools note that standard drain traps can dry out and let sewer gases into a building, and that sink and toilet traps are seldom a problem because they are in continuous use. An empty suite takes that use away. EPA’s guidance for buildings with low or no use recommends that owners and managers flush the plumbing regularly and fill drain traps with water so sewer gases cannot enter during flushing. Assign it to: the building engineer or property manager, not the cleaning crew.
- The air. NOAA’s climate summary for Texas names the Gulf of Mexico as the state’s primary source of moisture, most readily available in the east, where Houston sits. EPA advises keeping indoor relative humidity below 60 percent, ideally between 30 and 50 percent, and an empty suite with its HVAC set back still has to hold that line. How a setback does it is laid out in our post on preventing mold in an office or commercial space. Assign it to: whoever runs the HVAC.
- Leaks after a storm. Bush Intercontinental averages about 52 inches of rain a year under the National Weather Service’s 1991–2020 normals, and a window or roof leak can run for weeks in a suite nobody walks. Assign it to: whoever walks the suite after heavy rain.
An occupied suite reports its own problems. An empty one waits for whoever was assigned to look.
How often: let the tour calendar set the rhythm
No universal interval for an empty suite would be honest, so we will not print one. Two rhythms work, and they combine well. The first is set by tours: a check and a touch-up before each scheduled showing, which our landlord page supports in its own words: “make-readies are scheduled around your leasing calendar”. The second is a recurring touch, with the suite riding on the building’s regular schedule, so a last-minute tour never walks into accumulated dust.
The right mix depends on three things you can observe: how often the suite is shown, how fast it starts to look neglected (walk it yourself the day before a tour and you will know), and the weather, since stormy weeks track more grit to the entries. The broker owns the tour calendar, so the simplest system is the broker telling the cleaning vendor when tours are booked, and the vendor confirming the suite was touched before the first one.
The lobby has to look leased
A prospect reaches your suite through everything else: the garage or the sidewalk, the lobby, the elevator, the corridor, often the shared restroom. Our landlord page says what that route asks of an owner: “Commercial property owners carry the common areas even when suites sit empty — the lobby and corridors have to look fully leased for every prospect walkthrough.” That route is janitorial work rather than suite cleaning, and our janitorial page for Houston draws the line in one answer: “Scope, not skill. Office cleaning is a tenant suite; janitorial is the property — common areas, circulation and shared facilities on a nightly or set weekly rhythm.”
Paperwork your ledger and your broker can use
Empty space creates two kinds of cleaning cost, the common areas and the vacant suite’s make-ready, and they should not share a line. Your leases decide which costs tenants share, so ask for the two itemized separately and let the lease and your accountant settle where each one lands. That is general information, not accounting or legal advice. Our landlord page names the risk, “Tenants audit their CAM statements — a cleaning invoice that is not itemized by building and frequency turns into a pass-through dispute at reconciliation”, and the fix: “Per-building scheduling with one invoice itemized for CAM reconciliation and tenant billback”. The same page offers “a COI within 2 business hours of asking”, and for the broker: “On eligible completed visits you get CleanCheck photo proof, useful when your broker asks if the space is showable.”
The contract terms behind all of this are taken apart clause by clause in what should be included in a commercial cleaning contract.
What we do, and what we won’t claim
What we do is the landlord’s side of the building, in the words of our landlord page: “We clean what the landlord controls: common areas, shared restrooms, and vacant suites.”
What we don’t do matters just as much in an empty suite. We don’t do plumbing or HVAC work, repairs or pest control, so those lines go to the people named above. We don’t staff day porters. We don’t strip and wax, screen or refinish floors, and we don’t shampoo or extract carpet; if the make-ready needs any of that, book a flooring or carpet contractor and tell us the date, so the clean lands in the right order.
And we won’t claim that a clean suite leases faster, or that cleaning makes the air or the water in an empty space safe. A clean suite removes an easy reason for a prospect to say no. The rest is up to the space, the price and your broker.
FAQ
Do you clean occupied tenant suites?
Only when you or the tenant arrange it. As our landlord page explains, “Under most leases an occupied suite is the tenant’s own obligation,” and “when a tenant wants their own service, we quote them separately so the charge never muddies your CAM ledger.”
Can a vacant suite be turned before a showing?
Yes. Our landlord page says “make-readies are scheduled around your leasing calendar”, each one “scoped at the walkthrough: floors, storefront glass, restrooms, and dust from the build-out or the previous tenant.” Book it when the tour is booked, not the morning of.
Who handles the dust from a build-out?
The contractor hauls the debris; the fine dust is a post-construction clean, scheduled after the trades are out and before the listing photos. Our Houston post-construction page explains the second pass: “Construction dust settles twice, so this is scoped as more than one pass.”
Do you provide a day porter?
No. We don’t staff day porters, and we won’t promise daytime coverage we can’t provide. A vacant suite seldom needs one anyway: it needs the make-ready, a scheduled touch and a check before each tour.
