It is a Saturday in January, and a retired deacon is standing on a stepladder in the children’s wing with a box of air filters, pushing up ceiling tiles until he finds the unit he is looking for. He is the only person in the church who knows where all eleven of them are. He does this four times a year, for free, because someone has to, and when he eventually steps down nobody will know the job exists until the heat pumps start to fail. Church building maintenance is rarely discussed in design meetings, but this scene is decided there, years before anyone climbs the ladder. Most church buildings are designed for the hour on Sunday morning when they are full. They are run, for the other 167 hours of the week, by people who were never in the room when the drawings were made. We design for those people, and that habit is one of the clearest differences between an architect who has followed a thousand churches into their second and third decades and one who has not.

Who actually runs a church building

The National Congregations Study is the most careful picture we have of American congregations, and its 2021 report, built on data gathered in 2018 and 2019, is worth reading for anyone planning a church building. Only about 58 percent of congregations are led by a paid full-time leader. Another 23 percent are led by a paid part-time leader, and 19 percent are led by unpaid volunteers. In smaller congregations the picture tightens considerably, and those are the congregations UNITE serves most often. The study counts ministerial staff, not custodians or facilities staff, so it does not measure maintenance help directly. But the inference is not hard to draw: a congregation that cannot fund a full-time pastor is not funding a full-time facilities manager.

So who runs the building? In our experience it is some mix of the pastor, a part-time custodian, a few dependable volunteers with practical skills, and a service contractor who is called when something breaks. The volunteers are usually generous, capable, and older than the building committee would like to admit. They change filters, reset breakers, program thermostats, chase roof leaks, and know which door sticks in wet weather. None of them chose the equipment they maintain. None of them were asked where it should go. And the knowledge they carry lives in their heads rather than on paper, which means it leaves when they do, the same way a project’s reasoning leaves when the person who started it moves on.

Why church building maintenance is decided in design

The cost of a building does not stop at the ribbon cutting, and most of it comes later. A 2001 National Research Council guide prepared for the Federal Facilities Council estimated that design and construction account for only 5 to 10 percent of a facility’s total life-cycle cost, while operation and maintenance account for 60 to 85 percent. Those figures describe long-lived federal buildings with professional facilities staff, and a church’s proportions will differ. The direction does not. The money spent running a building over thirty years dwarfs the money spent drawing it, and nearly every factor that drives the running cost is fixed by decisions made in schematic design and design development.

Consider what gets decided on paper. Where the mechanical equipment sits, and how a person reaches it. Whether the filters are above a classroom ceiling or behind a door in a corridor. Whether the sanctuary light fixtures hang thirty feet over a sloped floor where only a rented lift can reach them. Whether the control system is something a volunteer can adjust for a Wednesday funeral or something only a technician with a laptop can change. Whether the flooring in the preschool rooms is a single sheet that must be replaced wall to wall or carpet tile that can be swapped one square at a time. Each of these is a small line in the drawings. Each one becomes a recurring cost, a recurring chore, or a recurring risk that someone at the church will carry for decades.

That is the real trade. A building that only a specialist can maintain will be maintained only when the church can afford a specialist. In practice that means filters get changed late, small leaks become ceiling stains, thermostats are left on permanent hold because nobody remembers the password, and equipment that should last twenty years is replaced in twelve. None of that shows up in a construction bid. All of it shows up in the operating budget, and in the slow drift of a building from something the congregation is proud of to something it apologizes for.

What that looks like in the drawings

The building code sets a floor, and it is worth knowing where the floor is. The 2021 International Mechanical Code, in section 306.1, requires that appliances and HVAC components be accessible for inspection, service, repair, and replacement without removing permanent construction, with a level working space at least 30 inches by 30 inches in front of the control side. Section 306.5 requires a permanent means of access, not a portable ladder, when a person must climb more than 16 feet above grade to reach rooftop equipment. Those are sensible minimums written with a trained service technician in mind. They say nothing about whether a retired volunteer can safely change a filter alone on a weekday morning, and that is the question we ask.

Asking it changes the drawings in specific ways. We look for mechanical rooms and closets that open off a corridor rather than equipment tucked above finished ceilings, so routine service does not mean moving furniture and disturbing a classroom. Where rooftop units make sense, we consider the route from the ground to the roof as part of the design rather than an afterthought, and where the site allows, we weigh ground-mounted equipment in a screened yard against the roof. In tall worship rooms we think about relamping before we select fixtures: long-life LED sources, fixtures that can be reached from a catwalk or lowered, and a layout that does not require a lift to be maneuvered between fixed seating. We label shutoff valves and electrical panels in plain language that matches the room names the congregation actually uses, not the room numbers on the drawings. And we favor control systems that a local service company can support. A sophisticated proprietary system serviced by a single dealer three hours away is not an asset to a church in a small town.

Finishes follow the same logic. We put durable wall protection in the corridors where carts, strollers, and folding tables travel. We specify flooring in children’s areas that can be repaired in sections. We place storage next to the rooms where chairs and tables are set up and torn down, because a fellowship hall that takes twelve volunteers ninety minutes to flip will soon take three volunteers three hours, and then it will not be flipped at all. Exterior details get the same scrutiny: gutters and downspouts that can be cleaned from a reasonable ladder position, sealant joints that can be reached, and landscape beds that do not trap water against the foundation. None of these choices is dramatic. Together they decide whether the building is easy or hard to take care of.

How we find out who will run it

The fix starts in programming, which is where most design decisions begin. Alongside the usual questions about seating counts, classrooms, and parking, we ask about operations: who opens the building on a weekday, who has the keys to the mechanical room, what the custodial budget is, which service contractors the church already trusts, and which parts of the current building cause the most complaints. Those answers belong in the building program as firmly as the number of nursery rooms. They are not glamorous, but a program that records them produces a building that fits the organization instead of one that fits a generic church.

Then we bring the people who will maintain the building into the design reviews. A short session with the volunteer who changes the filters, or the part-time custodian, often surfaces things no one on the building committee would think to mention: the closet that floods, the outlet that is always needed and never there, the door that has to be propped open every Sunday because the hardware fights the wind. Their knowledge of the existing building is free expertise, and it is usually gone by the time anyone thinks to ask for it.

Finally, we treat the hand-off as part of the work. At closeout we walk the people who will run the building through its systems in person, show them where every filter and shutoff is, and make sure the operation and maintenance manuals are organized for the people who will read them rather than filed and forgotten. That walkthrough matters most during the first year after move-in, when warranties are running and small problems are still the contractor’s to fix. A volunteer who knows what normal looks like is the person most likely to notice when something is not.

When simpler is not cheaper

There is a fair objection to all of this, and it deserves a straight answer. The maintenance-friendly choice is sometimes the more expensive one on bid day. A mechanical room with a corridor door takes floor area that an above-ceiling unit does not. A screened equipment yard needs a slab, fencing, and longer refrigerant runs. A catwalk over a worship room is real steel and real money. A building committee looking at a bid that is already over budget will be tempted to cut exactly these items, because they do not appear in the renderings and no donor asked for them.

Sometimes cutting them is the right call, and we will say so. The goal is not the lowest-tech building or the most expensive one. It is a building matched to the organization that will run it. A large church with a facilities director and a maintenance budget may be well served by a sophisticated building automation system that would bury a smaller congregation. A small church may be better served by fewer, simpler systems that its volunteers understand completely. What we resist is making that choice by accident, through cuts made late in the process by people who will never climb the ladder. When we bring options to a budget conversation, the operating consequence of each one is on the table alongside the first cost, so the committee knows what it is trading.

At UNITE, the habit of designing for the people who will run a building comes from following churches long after the ribbon cutting. Across more than 1,000 church projects, we have seen which decisions age well and which ones turn into a volunteer’s quarterly ordeal, and we bring that pattern recognition into programming, design reviews, and closeout rather than leaving it for the congregation to discover. We ask who will take care of the building before we decide where the equipment goes, and we put the operating consequences of each option in front of you while there is still time to choose. If you are planning a new building or a renovation and want it to be one your people can care for, we would be glad to start that conversation.
