The maintenance call you remember is the 11 p.m. text on a Saturday — guest has no hot water, you can’t reach a plumber until Monday, the next guest checks in Tuesday. That call wasn’t a surprise. It was a missed quarterly task that escalated because nobody had a schedule.
Maintenance is one of two operational failure modes:
- Reactive. Something breaks, you fix it under time pressure at premium cost.
- Scheduled. The same fix happens before failure, on cadence, at trade rate, between bookings.
The whole job of an STR maintenance schedule is to migrate as many items as possible from the first column to the second.
The four-tier framework
Every maintenance task lives on exactly one of four cadences:
- Per-turn. Done by your cleaner during every changeover. Cost: zero (already paying for the turn). Items here are checks, not repairs.
- Monthly. Done by you, your handyman, or a maintenance subscription. Cost: $50–$200/month equivalent.
- Quarterly. Slightly bigger items, on a rolling 4-times-a-year schedule. Cost: $200–$500/quarter equivalent.
- Annual. The big-ticket service items, ideally booked into the off-season.
A single property running this framework spends maybe $100/month all-in on maintenance, against an unscheduled environment that averages $250/month with worse outcomes.
What goes on each tier
Per-turn (the cleaner does it)
- Smoke detector chirp check (visual + listen).
- HVAC vent visual — no obvious dust loaf.
- Toilet flush + listen for run-on.
- Drain test in every sink and tub (10-second run).
- Lightbulb check — every fixture, every room.
- Lockbox / smart lock battery indicator.
- TV remote battery indicator.
These are 5 minutes added to the standard turn. They’re checks, not repairs. The cleaner reports failures via dispatch, you triage.
Monthly
- Air filter replacement (HVAC). Most properties run an MERV 8–11. Replace monthly, not quarterly. The marketing on the box is residential, not nightly-rental.
- Garbage disposal flush (ice + citrus).
- Dishwasher cleaner cycle.
- Washing machine cleaner cycle (HE detergent residue is the most common smell complaint).
- Vacuum filter check + replacement.
- Pest control inspection or service.
Quarterly
- HVAC drain line check (algae block = water on the floor next summer).
- Water heater inspection — no leaks at the connections, anode rod check on year 5+.
- Refrigerator coil clean (skipped = early compressor failure).
- Range hood filter replacement.
- Dryer vent clean (skipped = fire risk, listed as #1 cause of dryer fires by USFA).
- Smoke + CO detector full battery replacement.
- Caulking inspection (bath, kitchen).
- Lockbox / smart lock battery replacement before the on-board low warning.
Annual
- HVAC professional service (one in spring for AC, one in fall for furnace — count as two annual events).
- Chimney inspection (if applicable).
- Roof inspection.
- Termite / pest inspection.
- Septic pump (every 3–5 years depending).
- Deep grout clean / re-seal.
- Mattress flip + protector replacement.
- Carpet professional clean.
- Furnace humidifier filter (if applicable).
Why HVAC and smoke detectors get top billing
Two categories deserve disproportionate attention:
HVAC because it’s the single most common reason a guest leaves a 3-star review for an otherwise 5-star property. “Stuffy,” “didn’t cool,” “loud” — all of those are filter-and-service issues. HVAC failure is also the most expensive emergency call: $400+ for after-hours service, $2,000+ for a refrigerant recharge, $5,000+ for a compressor.
Smoke and CO detectors because they’re a regulatory and legal floor. Most jurisdictions require working smoke detectors as a condition of any rental — and most insurance policies have a clause about working detectors at time of incident. The quarterly battery replacement and the per-turn chirp check exist together for a reason.
The line items first-year hosts skip
Three categories that show up in year 2 if you skip them:
- Anode rod (water heater). Sacrificial component that protects the tank. Lifetime is 4–6 years in most water; once it’s gone, the tank starts corroding. A $30 part replaced on schedule is a $1,200 water heater replacement avoided.
- Dryer vent. Lint accumulates inside the duct, not just the trap. Annual professional cleaning is $80–$150, an undocumented cause of slow-drying complaints, and the leading cause of dryer fires.
- Caulking. Failed caulking around a tub or shower lets water into the subfloor for months before the ceiling stain appears in the unit below. $20 of new caulking on a quarterly cadence prevents a $4,000 subfloor and ceiling repair.
These items are unsexy. They also don’t break loudly until they break expensively.
The maintenance schedule generator
The maintenance schedule generator takes your property’s profile (HVAC type, water heater type, fireplace, septic, etc.) and produces an annual schedule with per-turn, monthly, quarterly, and annual tasks. It exports to PDF for your handyman and to .ics so the cadence shows up in your calendar.
Pair it with the restock calculator so consumables (filters, batteries, caulk) are part of your monthly buy, not a panic Amazon order at 11 p.m. on a Saturday. The whole point is to keep the failure mode boring.
