Quick Answer
Before South Florida’s dry season ends, your HOA needs a written, photo-documented irrigation audit covering zone pressure and coverage, controller programming compliance with SFWMD restrictions, head condition, and sensor function. The audit should happen in February or March. If your contractor cannot produce that report within 48 hours of the walk, you have no record to enforce against and no baseline for next year.
Why Timing Matters: February and March Are the Window
South Florida’s dry season runs roughly November through April. By the time summer rains arrive in late May or June, wet conditions mask problems that have been quietly running up your water bill for months. A broken rotor that drenches a sidewalk instead of turf is obvious in February. In July, with daily afternoon storms, nobody notices it until the water bill arrives.
The two-month window before the seasonal shift is when deficiencies are most visible and most correctable. A board that waits until summer to schedule an audit is working against itself.
What Should the Audit Actually Cover?
A thorough pre-dry-season audit has five components. If your contractor is not addressing all five, the audit is incomplete.
Zone-by-Zone Pressure and Coverage Check
Every zone needs to be cycled and observed. Low pressure means poor coverage and dry spots. High pressure causes misting, which puts water into the air instead of the root zone. A technician walking the property while the system runs is the only way to catch these conditions.
Controller Programming Review Against Current SFWMD Restrictions
Palm Beach, Broward, and Miami-Dade are each governed by their own water management district rules, and address-specific day assignments vary. Your contractor should know your property’s assigned watering days without being asked. The audit should confirm that the controller is programmed to those days and that start times fall within the permitted windows.
Two common controller failures the audit should flag:
Summer runtimes still active. Many contractors set aggressive summer schedules in June and never dial them back in November. The system runs through dry season on summer programming, overwatering turf that does not need it and running up the bill.
Seasonal adjust set too high. Dry-season programming in South Florida typically runs the water budget feature between 60% and 80% depending on plant type and sun exposure. A dial left at 100% in February is not a minor setting, it is a billing problem.
Head-to-Head Inspection for Broken or Misaligned Heads
Rotors and spray heads break, sink, and drift over time. A head that is misaligned by 15 degrees waters a parking lot curb instead of turf. The inspection should document every broken, clogged, or misdirected head with a photo, not a verbal note.
Rain Sensor and Soil Moisture Sensor Function Test
Rain sensor bypass switches left in the manual or bypass position are one of the most common findings and one of the most expensive. A bypassed sensor runs your irrigation through every storm, regardless of what fell the night before.
If your property has a smart or ET-based controller with a soil moisture sensor, that sensor needs to be confirmed connected and actively reading. If you paid for a smart controller and the sensor is disconnected, you are running dumb scheduling at smart-controller prices. The audit should test both components and document the result.
Written Report With Photos Documenting Every Deficiency
This is the part most contractors skip or shortchange. A verbal walkthrough summary is not an audit. It is a conversation. Conversations cannot be attached to a board meeting packet, cannot be referenced at contract renewal, and cannot be used to hold a contractor accountable six months later.
What the Written Report Should Include
A complete audit report should contain all of the following:
- Property address and date of inspection
- Total number of zones inspected
- Per-zone findings with photos, covering broken heads, pressure issues, and coverage gaps
- Controller schedule as-found and as-corrected
- Rain sensor and soil moisture sensor test results
- List of repairs completed same-day versus repairs requiring a return visit, with estimated return dates
- Recommended upgrades with cost estimates listed separately from the maintenance scope
- Technician name and license number
If your contractor cannot produce this document within 48 hours of the audit walk, that is a process gap. A board that accepts a verbal summary in place of a written report has no record to enforce against and no baseline for comparison when the next dry season arrives.
What Happens If You Skip the Audit?
The cost of skipping is not dramatic or sudden. It accumulates quietly. A rain sensor in bypass runs your system through a week of afternoon storms in June. A summer schedule left active through February runs 20-minute zones in a month when 10 minutes would cover it. A broken rotor drowns turf in one spot and starves it in another.
None of these failures announce themselves. They show up as a water bill your treasurer flags in March, as sod replacement costs in May, or as a violation notice from your municipality for watering on the wrong day.
The audit is how a board gets ahead of that cost instead of explaining it after the fact.
Frequently Asked Questions
How often should an HOA irrigation system be audited?
At minimum, once per year before dry season ends. High-use properties with older heads or high water costs may benefit from a mid-summer check as well, particularly after the controller schedule is updated for summer runtimes.
Does the audit have to be done by a licensed irrigation contractor?
In Florida, irrigation system work requires a licensed contractor. Your audit technician should be able to provide a license number on the report itself. If a report arrives without technician credentials, ask before accepting it.
What if the audit finds violations of our SFWMD watering restrictions?
The controller should be corrected the same day if the technician can access it. The audit report should document the as-found programming and the corrected programming. If a violation has already been issued, the corrected report becomes part of your response documentation.
How do we know if our contractor is actually running all five components?
Ask for the report first. A contractor who has been running complete audits will have a template ready. One who has been doing verbal walkthroughs will need to build one. You can also ask to walk one zone with the technician during the inspection. Watching the cycle and the pressure test on a single zone tells you whether the work is real.
Is this audit typically included in a standard landscape maintenance contract?
It depends on how the contract is written. Many landscape maintenance contracts include irrigation monitoring but not a documented annual audit with the reporting components described here. Boards should confirm in writing whether the annual audit and report are included or whether they carry a separate service charge.
