The problem
Church buildings are among the most under-used real estate. Tim Cool of Smart Church Solutions puts it bluntly: "Next to the NFL, churches are the worst user of real estate… built to be underutilized." A widely cited figure is that about 75% of churches use their facilities only ~25–30% of a typical week. The building is the largest line item after staff, yet most rooms sit empty most of the week — and the instinctive response to a crunch is "we need to build," when the real answer is often "we need to schedule differently."
What good looks like
A room-by-room, hour-by-hour heatmap built from Google Calendar + Planning Center bookings, with a cost-per-hour overlay (allocate mortgage + utilities + cleaning per room), flagging rooms idle 90%+ of the week. The output reframes the conversation in dollars: "Room B is used 6% of available hours at $X per used hour — consolidate or repurpose."
Market scan
| Tool | Fit | Pricing (verify) |
|---|---|---|
| Planning Center Calendar | Room/resource scheduling; booking-centric reporting | À-la-carte |
| Skedda | Space-booking software | $249–349/mo |
| FMX | Facilities + scheduling + work orders | Quote-based ~$20–100/user/mo |
| eSPACE (Smart Church Solutions) | Church event scheduler + facility stewardship | ~$60/mo to custom |
| Connecteam | Staff scheduling/ops (adjacent) | Free up to 10; $29–35/mo for 30 |
The gap: these tools book rooms; none natively shows a utilization heatmap with a cost-per-hour overlay that converts idle space into dollars and auto-flags under-used rooms. That financial framing — tying empty rooms to allocated facility cost — is the DIY differentiator.
Data privacy & security
- Lowest-sensitivity build in the set: room names, times, event titles. No giving data.
- Watch one thing: event titles can reveal sensitive groups (recovery, counseling). Strip or aggregate titles to room-level usage before display or any LLM use.
- Standard auth still applies.
How to build it
- Read bookings via the Google Calendar API and the Planning Center Calendar API.
- Normalize to a room × hour grid.
- Enter a per-room cost basis (square-foot share of annual facility cost ÷ available hours).
- Render the heatmap (hours × rooms).
- Compute utilization % and cost-per-used-hour; flag rooms under a threshold.
- Add an AI-written recommendation line per under-used room (on stripped, room-level data only).
Rollout plan
- Q1: Get all room bookings into Planning Center Calendar (or a single calendar). Pull four weeks of data.
- Q2: Build the heatmap and enter the cost basis.
- Q3: Take the cost-per-used-hour findings to the budget/facilities conversation.
Effort & cost
- Build: ~20–35 hours — the smallest build in the set; the grid and cost math are straightforward, the heatmap viz is the main UI work.
- Run: under ~$30/mo; the Google Calendar API is free.

Honesty flag: the precise "~10–30%" eSPACE-attributed utilization percentage is unverified; the "worst user of real estate" framing and the ~25–30% figure are the citable versions.
