Self-monitoring under the Swedish Environmental Code

Egenkontroll — self-monitoring — is the property owner's own continuous work of planning and checking operations so that they do not harm human health or the environment. The requirement sits in Chapter 26, Section 19 of the Swedish Environmental Code (miljöbalken) and applies to anyone who conducts an operation. Owning and letting residential property is an operation in the Code's sense. The supervisory authority is the municipal environmental committee (miljönämnden).

It is the provision that ties almost everything else together: radon, ventilation, damp, temperature, noise, water and pests are all judged against the same requirement.

The duty comes from two directions

Provision	What it says
Environmental Code, Ch. 9 s. 9	Dwellings must be used so that no detriment to human health arises, and the owner must take the measures that can reasonably be required
Environmental Code, Ch. 26 s. 19	The operator must continuously plan and check the operation to counteract and prevent such detriment

The first says what must be achieved, the second says that you must keep track of it yourself. The environmental committee checks that you do — it does not inspect the building for you.

The nuance that decides how formal this has to be

There is a separate Ordinance (1998:901) on operators' self-monitoring with detailed formal requirements: documented allocation of responsibility, written routines, documented risk assessment. It is frequently cited as if it applied to all property owners. It does not.

The ordinance applies to those who professionally conduct permit- or notification-liable operations under Chapters 9 or 11–14 of the Environmental Code. An ordinary residential portfolio is normally neither, so the ordinance's formal requirements do not apply directly.

That does not mean you are exempt from self-monitoring. Chapter 26, Section 19 applies in full. The difference is that the law prescribes no template — you choose the form and scope yourself, sized to the portfolio.

In practice that is a comfortable freedom with an uncomfortable flip side: when the environmental committee asks what you do, there is no form to point at, only what you can actually show.

Does self-monitoring have to be in writing?

For a residential portfolio there is no explicit written-form requirement in Chapter 26, Section 19. But the burden of proof is effectively reversed at inspection: the committee asks what you check, how often, who does it, and what happened to what was found. "We do it, we just don't write it down" leads at best to an order to present your routines. A simple written routine is cheaper than that conversation, and it is the conclusion the Public Health Agency's guidance reaches as well.

What self-monitoring usually covers in residential property

• Ventilation and air quality — that the system works between the mandatory inspections, not only on inspection day.
• Damp and mould — routines for water damage, wet rooms, leaks.
• Temperature — see the reference values in HSLF-FS 2024:10.
• Radon — measurement, results and remediation, see radon measurement.
• Tap water — temperatures and stagnant water, see legionella.
• Noise — installations, lifts, fans, ventilation.
• Pests and waste — routines and response when reported.
• Complaint handling — how a resident's report is received, investigated and closed.

The last point is the one usually missing and the one inspectors notice first. A complaint about a cold flat that was answered verbally and never logged does not exist when the committee asks about it a year later.

Self-monitoring is not the same as the statutory inspections

The two are constantly confused, and the difference is simple:

• The statutory inspections — ventilation control (OVK), energy performance certificate, radon measurement, refrigerant leak checks — are point-in-time checks carried out by a qualified third party at fixed intervals. See the annual calendar.
• Self-monitoring is your own continuous work in between, with no statutory interval and no certified performer.

A passed ventilation inspection says the system worked that day. Self-monitoring is what should catch an extract fan failing seven months later. That is why an owner can have every certificate in order and still fail on self-monitoring — and the reverse.

What supervision looks like

The environmental committee acts both on resident complaints and on planned campaigns against portfolios. A typical case runs:

1. A request to account for your self-monitoring — often a letter with questions rather than a visit.
2. Inspection of the building or the flat the complaint concerns.
3. Measurement where needed, for example of temperature or ventilation.
4. An order to investigate or remedy, coupled with a financial penalty (vite) if required.

Step one is decisive. A portfolio that can answer with existing routines and a log of completed checks rarely reaches step four.

Getting started without building a system first

1. List what can actually go wrong in your buildings — start from the complaints you have had, not from a template.
2. Assign an owner to each area, by name.
3. Set an interval per checkpoint, even if it is "once a year".
4. Walk the round once and adjust the list against what turned out to be missing.
5. Decide how a complaint is registered and when it counts as closed.
6. Only then choose where it is logged.

The order is deliberate and matches systematic fire safety work. Most organisations start at step six.

Where Emphyx fits

Emphyx covers the part of self-monitoring that is about knowing status per building: regulatory compliance collects what has been inspected, what has expired and what is missing, and inspection rounds and fire safety provide checklists, deviations with photos and history per building.

We do not write your self-monitoring plan, make no risk assessment and measure nothing ourselves. Judging what constitutes a detriment to human health is yours and the environmental committee's, not a system's.
