If you're a builder, electrician, plumber, or insulation installer, there's a steady stream of compliance work flowing through the rental property market right now — and most landlords are still scrambling to keep up.
From 2026, every private rental property in New Zealand must meet the full Healthy Homes Standards from the very first day of any new or renewed tenancy. The 120-day grace period that previously applied is gone. The property must be compliant the moment keys change hands.
For landlords, that's significant pressure. For tradies with the right skills, it's a reliable pipeline of work.
What the Healthy Homes Standards Actually Require
There are five standards, and each one typically needs a licensed professional to either assess or complete the work.
1. Heating
A fixed heater must be able to heat the main living area to at least 18°C. The heater must be an approved type — wood burners, open fires, and unflued gas heaters generally don't qualify.
In practice, most landlords install a heat pump or a fixed electric heater sized correctly for the room. This is work for electricians (installation and wiring) and sometimes HVAC specialists. The heating capacity calculation is based on the room's floor area, ceiling height, and insulation level.
Trade opportunity: Heat pump installation, electric heater wiring, load calculations.
2. Insulation
Ceiling and underfloor insulation has been compulsory since 2019, but the Healthy Homes standard is more specific — it sets minimum R-values and requires existing insulation to be assessed and topped up or replaced if it doesn't meet the threshold.
Ceiling insulation must achieve R-3.3 in most of the North Island and R-6.6 in colder regions (Southland, Central Otago, most of the South Island). Underfloor insulation must reach R-1.3.
Trade opportunity: Insulation assessment, top-up, and full replacement. Particularly strong in older housing stock (pre-1990s) where existing insulation is often insufficient or degraded.
3. Ventilation
Every kitchen must have an extractor fan that vents to the outside. Every bathroom (including en suites) and toilet must have an extractor fan or openable window.
The fans must meet minimum extraction rates: 50 litres per second for kitchens, 25 litres per second for bathrooms. Many older rental properties have fans that don't meet these specifications, or extract to the ceiling cavity rather than outside.
Trade opportunity: Fan replacement and installation, ducting to exterior, wiring. Electricians and builders both play a role depending on whether new ducting is needed.
4. Moisture Ingress and Drainage
Properties must have efficient drainage for gutters, downpipes, and drains. If there's an enclosed subfloor space, a ground moisture barrier (polythene sheet) must be installed.
Ground moisture barriers are a straightforward install for builders and can often be done in a day on a standard house. Assessment is the first step — many older properties have subfloor spaces that have never been assessed.
Trade opportunity: Ground moisture barrier installation, drainage assessment and repairs, gutter and downpipe work.
5. Draught Stopping
Landlords must block unreasonable gaps in walls, ceilings, windows, floors, and doors that cause noticeable draughts. This is often the most overlooked standard and involves gaps around pipes, chimneys, skylights, and joins between different building materials.
Trade opportunity: Draught-stopping remediation — typically builder or handyman work, but can involve plumbers where gaps are around pipes.
The Compliance Assessment: Your Entry Point
A standard Healthy Homes assessment costs $200–$300 + GST for a typical three-bedroom rental. Landlords need an assessment to understand what work is required — and many are getting assessments done without understanding what comes next.
If you offer assessments (or partner with someone who does), you become the natural first call when the landlord needs the actual work done. Many tradies in the insulation and heat pump industries now offer an assessment-to-installation pipeline as a single service.
The penalty for non-compliance is up to $7,200 — enough motivation for most landlords to act quickly once they understand the risk.
Why 2026 Is the Peak Year for This Work
The compliance deadline has tightened significantly. In previous years, landlords had time between tenancy agreements to get work done. Now there's no buffer — compliance is required on day one of every new or renewed tenancy.
With tenancy turnover accelerating in some markets, landlords who haven't yet fully complied are increasingly exposed. Property managers are also under pressure because they're responsible for ensuring the properties they manage are compliant — and many are actively pushing landlords to get work done.
The volume of compliance work available in 2026 is substantial. It's not the kind of work that generates referrals through word of mouth the way a great kitchen renovation does — but it's consistent, repeatable, and often leads to ongoing maintenance relationships with landlords.
How to Position Your Business for Healthy Homes Work
Get the assessments flowing to you
Approach local property managers. They manage dozens or hundreds of properties and need reliable trades to handle compliance work. A relationship with two or three active property management companies can provide consistent work.
Pitch: "We can assess and complete all Healthy Homes compliance work — heating, insulation, ventilation, moisture barriers. We'll turn around a quote within 48 hours."
Specialise in one standard and own it
If you're an electrician, focus on the heating and ventilation standards. If you're an insulation installer, own the insulation and moisture standards. Being known as the go-to person for a specific standard in your area is more effective than trying to cover all five.
Bundle the work
Many landlords need multiple standards addressed. A builder who can coordinate insulation installers, an electrician, and do the moisture barrier themselves becomes very attractive because the landlord only has one point of contact. Use Fergus or Tradify to manage multi-trade jobs cleanly — scheduling, quotes, and compliance documentation in one place.
Use compliance documentation as a selling point
Landlords need documentation to prove compliance. If you provide a proper compliance certificate or inspection report alongside the completed work, you're removing a headache for them. This is a differentiator from tradies who just do the work and leave.
