A quarterly inspection is the cheapest maintenance you will ever do. Thirty minutes, four times a year, and you find the slow drip under the sink in month three instead of the rotted cabinet floor in month eighteen. You also see the unit while the tenant still lives there, which is the only time a small problem is still small.
It is also the visit tenants like least, so the way you set it up matters as much as the list.
Put it in the lease, then give notice every time
Tell the tenant at signing that you check the unit every three months and what the visit is for: smoke and carbon monoxide alarms, filters, leaks, and anything that needs repair. A visit the tenant expected since day one goes very differently from one that shows up out of nowhere.
Then send notice before each visit, every time, even if the lease already mentions it.
In California, Civil Code § 1954 sets the rules. A landlord may enter only in the cases the statute lists, and a general look around the unit is not one of them by name. Subdivision (a)(2) covers entry to make necessary or agreed repairs or to supply necessary or agreed services, so plan the visit around that work and describe it that way: testing alarms, changing the filter, checking for leaks. The notice itself has to be in writing and include the date, the approximate time, and the purpose of the entry. Twenty-four hours is presumed reasonable notice, and a mailed notice sent at least six days ahead is presumed reasonable too. Entry happens during normal business hours unless the tenant agrees otherwise at the time, and § 1954(c) bars using the right of access to harass a tenant.
Two shortcuts the statute allows. You and the tenant can agree orally on a visit for agreed repairs or services, as long as the date and approximate time are set and fall within a week of the agreement (§ 1954(d)(3)). And no notice is needed if the tenant is home and agrees to the entry at the time (§ 1954(e)(2)). Written notice is still the cleaner record.
Outside California, entry rules vary by state, and some states set no fixed notice period at all. Check yours before the first visit, and send written notice anyway.
A notice that works:
NOTICE OF ENTRY
To: [tenant name(s)], [address and unit]
Date of entry: [day, date]
Approximate time: [10:00 a.m. to 11:00 a.m.]
Purpose: Quarterly maintenance visit: test smoke and carbon monoxide
alarms, replace the HVAC filter, check under sinks and around
the water heater for leaks, and note any needed repairs.
You are welcome to be present. If this time does not work, reply
with a time that does and we will reschedule.

The checklist
Print one copy per visit. Mark each line OK, Fix, or Watch, and write a short note next to anything that is not OK. Take a photo of every Fix and every Watch.
Safety (do these first, every time)
- Each smoke alarm sounds on test
- Each carbon monoxide alarm sounds on test
- Fire extinguisher present, gauge in the green
- Nothing stored against the water heater or furnace
- Exterior doors lock; any window locks work
Kitchen
- Under the sink: dry cabinet floor, no drip at the trap or supply lines
- Faucet does not drip or leak at the base
- Dishwasher: no water on the floor in front of it
- Range hood fan and light work
- Refrigerator seal closes; no water under the unit
Bathrooms
- Toilet does not run, rock, or leak at the base
- Caulk around the tub and shower is intact
- Exhaust fan runs
- No soft spots in the floor near the toilet or tub
- No mold beyond surface spotting
Mechanical
- HVAC filter replaced (write the size on the sheet)
- Water heater: no rust at the base, no water in the pan
- No new stains on ceilings under bathrooms or the roofline
Every other room
- Walls and ceilings: no new water stains or cracks
- Windows open and close; screens in place
- Outlets and switches work and their covers are on
Outside
- Gutters and downspouts clear and draining away
- No standing water against the foundation
- Exterior lights work
Notice what is not on the list: how the tenant decorates, how clean the counters are, what is in the closet. You are there for the building, and the visit should stay inside the purpose written on the notice. Tenants can tell when an inspection turns into a judgment of how they live, and that is how a good tenant decides not to renew.
After the visit
- Sort what you found. A Fix that came from normal use goes on your repair list. A Fix that came from damage gets a dated photo and a note in the tenant’s file. A Watch gets checked again next quarter.
- Tell the tenant what happens next. A two-line message the same day: what you found, who is coming, and when. Silence after an inspection reads as either indifference or a deposit problem.
- Schedule the repairs. Any follow-up visit for those repairs needs its own notice, the same as the inspection did.
- File the sheet and the photos. Four dated inspections a year make a strong record to have when the move-out comes and someone asks whether that stain was always there.
The quarterly visit sits alongside the seasonal work on the building itself. The quarter-by-quarter maintenance checklist covers gutters, HVAC service, and the jobs to hand a vendor. When the tenancy ends, the move-out photos are easier to read against a run of dated inspections, and move-out photos that show wear vs damage explains how to shoot them. For the move-in baseline, see what to include in a rental condition report.
Each Fix can go straight into your work-order queue. Maintenance in LeaseRooster lets you assign a vendor, track the job to done, and offer the tenant a few time slots for the repair visit from the work order. The move-in and move-out condition reports give you the baseline at either end of the tenancy.
