Why the setup crew stays on site
The work happens under and around a home, not at a desk. Crews haul the sections in, set them on piers, level them, bolt the halves together, run the tie-downs and then connect water, waste and power. Every site is a little different: soft ground, a slope, an old pad, a hitch that will not line up. Software can plan that job. It cannot crawl under the unit and shim a pier.
That is the main reason the headline figure sits where it does. Our Still needs a human score for this job is 84 out of 100 (higher is safer), and the share of task time that stays with people is 92%. The robotics panel on this page puts the job in the dexterous humanoid tier, which means a machine would need hands, balance and judgment in a crawl space to take the work over.
There is a second reason. Installation is bound to state codes and manufacturer instructions, and a licensed installer signs off on the result. When a home settles or a line leaks, someone has to be accountable and come back out. Responsibility of that kind is hard to hand to a model.
What AI runs, what it assists, and what people keep
Start with the tasks AI can run on its own. That group is small and paperwork-shaped: pulling together setup records, drafting the job write-up after an inspection, and routine scheduling and estimating. Its share of task time is 0%. None of it touches the home itself.
The assisted group is bigger in value than in hours. Software helps read manufacturer setup manuals and state installation standards, flags the pier spacing or anchor pattern a given model calls for, and helps a crew lead sequence a day across two or three sites. It can help explain a fault in a furnace or a water heater before anyone drives out. The share here is 8%. In each case a person still decides and still does the work.
What people keep is the job itself: transporting and positioning the sections, blocking and leveling on the pad, joining the marriage line and sealing it, installing anchors and skirting, then connecting and testing plumbing, gas and electrical before handover. Repairs after the fact belong here too. Across all tasks, the coverage score, our answer to can AI do it, is 7. You can read how that number is built on the coverage method page.
How strong is the evidence?
Weak, and we say so. The evidence grade for parity, our answer to whether AI is better than a person at this work, is D. No study has tested an AI system or a robot against a qualified installer on a real setup, so there is no parity number on this page and we will not estimate one.
What would settle it is specific: a timed trial of a mobile robot leveling and blocking a single-wide on an uneven pad, a test of utility hookups passing a state inspection without a person touching them, and failure rates tracked over a season of weather. Until something like that exists, treat the parity slot as untested rather than favorable. The grading scale is explained on the quality parity page, and the full method sits at our methodology.
When the picture could change
Most likely after 2045 (8 in 10 of our scenarios). For what that window measures, see the replacement-year method.
Two things could pull it earlier. First, more of the house gets finished in the factory, so less has to be joined, sealed and trimmed on site. Second, general-purpose robots that can walk on rough ground and work with two hands keep improving, and the cost panel on this page shows an AI stack costing far less per month than a crew.
Two things hold it back. Site conditions are the big one: mud, slope, tight access and older pads defeat machines that need flat, predictable ground. The other is code and liability. State installation standards, manufacturer instructions and inspection sign-off all assume a licensed human installer, and that paperwork moves slower than the hardware.
Good to know: Hiring, not automation, is the live pressure here. The Bureau of Labor Statistics put median pay for this job at $45,990 and employment near 3,020, with about 5.8% growth projected to 2035 (BLS, 2025).
How to stay needed
Lean into the parts of the job no one can do remotely. Get fast and exact at leveling and anchoring, because that is where callbacks come from. Own the utility hookups and the test before handover. Take the repair and re-set work that comes a year later, when a home has settled and the original crew is gone.
Two skills carry the most weight. One is code fluency: knowing your state’s installation standards and the manufacturer’s manual well enough to argue a point with an inspector. The other is running a crew and a schedule, since supervising setups is where the pay and the stability sit.
What to do: Pick up your state installer certification if you do not have it, then add a second service line such as HVAC or septic hookup.
Close work is worth comparing. Look at installation and repair helpers, general maintenance and repair workers and RV service technicians, all of which share the same mix of travel, diagnosis and hands-on fixes. The wider installation and repair occupations family sets this job in context, and the construction sector page shows how site trades score together.
