Will a Renovation Wave Arrive Before 2029?
With the abolition of imputed rental value from 2029, many previous tax deductions for owner-occupied residential property will also disappear. This could bring forward renovations, maintenance work and energy-related upgrades.
In brief
A renovation wave before 2029 is possible, but not guaranteed. The reason: with the abolition of imputed rental value, many maintenance and renovation deductions for owner-occupied residential property will disappear or be significantly restricted. Homeowners may therefore bring forward larger works. Whether this becomes a broad wave depends on costs, interest rates, contractor capacity, permits, subsidy programmes and cantonal rules.
What does a renovation wave before 2029 mean?
A renovation wave means that many homeowners carry out renovations, maintenance or energy-related measures before the system change in home ownership taxation. Owner-occupied houses and condominiums are particularly relevant where certain maintenance costs could previously be taken into account for tax purposes.
The term does not mean that every owner-occupied home will be renovated by 2029. More likely are targeted pull-forward effects: anyone already planning to replace windows, renew heating, renovate the roof or carry out larger maintenance work may reassess the timing from a tax and financial perspective.
What changes from 2029?
From 1 January 2029, imputed rental value will be abolished for owner-occupied residential property. At the same time, many previous deductions for owner-occupied residential property will disappear, especially for property maintenance. For direct federal tax, previous deductions for investments in energy saving and environmental protection will also be abolished.
Why renovations might be brought forward
Tax deductions
Value-preserving maintenance could previously be relevant for tax purposes. The loss of these deductions may motivate homeowners to complete planned works before 2029.
Energy projects
Heating, insulation, windows or photovoltaics are often planned long term. Tax and subsidy rules can influence the timing.
Purchase decisions
Buyers examine properties in need of renovation more carefully because the tax treatment of maintenance changes from 2029.
A possible renovation wave would have limits. Contractors are not available without restriction, building permits take time, material prices may rise and not every tax-efficient measure is technically or financially feasible immediately. Selective pull-forward effects are therefore more likely than an even nationwide renovation wave.
Renovate before or after 2029?
| Aspect | Renovation before 2029 | Renovation from 2029 |
|---|---|---|
| Tax deductions | Maintenance and certain energy measures may still be relevant depending on the situation | For owner-occupied residential property, many deductions disappear or are restricted |
| Planning | Time pressure possible because quotes, permits and execution must be coordinated before 2029 | More time for technical planning, but potentially less tax relief |
| Costs | High demand may increase prices and waiting times | Less tax pressure, but construction costs and energy prices remain uncertain |
| Financing | Mortgage, liquidity and tax effect must be assessed together | Financing becomes more central because tax deductions help less |
| Energy renovation | Check subsidies and cantonal rules early | Cantons may continue to provide certain deductions or subsidies, but not everywhere equally |
| Buying an older property | Renovation needs may be assessed differently for tax purposes before 2029 | Purchase price and renovation budget must be calculated more conservatively without previous deductions |
Step by step: How homeowners can assess a renovation before 2029
- Assess renovation needs realistically: roof, façade, windows, heating, pipes, kitchen, bathroom and energy efficiency.
- Distinguish which works are value-preserving, value-increasing or energy-related.
- Review current tax deductions and cantonal rules with a specialist.
- Clarify subsidy programmes for energy, heating, insulation or solar early.
- Obtain quotes and check the availability of contractors, planners and energy advisers.
- Include permits, condominium ownership issues and neighbours in the planning early.
- Calculate financing, mortgage, liquidity and tax effects together.
- Do not renovate only for tax reasons; prioritise technical necessity and long-term value.
Assessment questions: Should I renovate before 2029?
The following questions help homeowners, buyers and advisers assess the right timing.
Assessment questions for renovation before 2029
1. Which maintenance works will be necessary in the next five years anyway?
2. Are the works value-preserving, value-increasing or energy-related?
3. Which deductions currently apply in my canton?
4. Which deductions will disappear from 2029 for owner-occupied residential property?
5. Are subsidies available for heating, insulation, windows, solar or energy advice?
6. Can planning, permits and execution realistically be completed before the end of 2028?
7. Are sufficient own funds or financing options available?
8. Will the renovation lead to lower energy costs or higher living comfort?
9. Could rising demand and contractor shortages increase costs?
10. Is the renovation still sensible in the long term without a tax advantage?Practical examples
Example 1: Single-family home with old heating
A family owns a single-family home with an old oil heating system and average insulation. The heating system must be replaced in the coming years anyway. Before 2029, the family checks whether a heat pump, insulation and window replacement can be combined so that technical necessity, subsidies and tax effects align.
Example 2: Condominium with planned bathroom renovation
A couple is planning a larger renovation of the bathroom, kitchen and flooring. Part of the work is value-preserving, while another part increases comfort and value. Before making a decision, the couple has it checked which costs are tax-relevant today and which works may be better implemented later.

Frequently asked questions about a possible renovation wave before 2029
Summary
Before 2029, Switzerland may see noticeable pull-forward effects in renovations. The reason is the system change in home ownership taxation: imputed rental value will disappear, while many previous maintenance and renovation deductions for owner-occupied residential property will also disappear. An automatic nationwide renovation wave is not certain, however. What matters are technical necessity, tax effect, financing, cantonal rules, subsidies and the availability of specialists. Homeowners and buyers should therefore not act hastily, but plan renovations early and review them properly from a tax perspective.
