Introduction
Learning how to increase apartment value starts with making the property safer, more efficient, and easier to live in. Fixing defects, updating dated rooms, improving storage, and reducing future costs can all make an apartment more attractive to buyers.
However, expensive work does not always deliver the best return. In Switzerland, owners must also consider local prices, PPE rules, building condition, taxes, and renovation permits. This guide from the Immobiliere Genevoise Blog explains where to invest first and how to avoid overspending.
How Can You Increase Apartment Value?
To increase apartment value, start by repairing defects and improving energy efficiency, layout, storage, lighting, the kitchen, and the bathroom. You should also check the condition and finances of the PPE before renovating. Finally, compare the expected rise in market value with the full cost of the work.
It helps to understand three types of value:
- Market value: What buyers may pay in the current market
- Appraised value: What a professional valuer or mortgage lender supports
- Perceived value: How attractive and move-in-ready the apartment feels
A renovation may improve all three, but there is no guarantee that every franc spent will return through a higher sale price.
Get an Apartment Valuation Before Renovating
Compare the Current and Renovated Value
Start with an “as-is” valuation. A local expert can compare the apartment with recent sales in the same commune or neighbourhood. The assessment should consider its floor, view, light, condition, layout, PPE charges, and building quality.
You can then ask which improvements may affect its resale value. This is more reliable than using an average price per square metre. Learn more about how to estimate your apartment’s current market value.
Set a Renovation Budget Based on Potential Return
Use a simple calculation before approving the work:
Formula
Expected increase in value − total renovation costs = projected net gain
Include architect or designer fees, permits, financing, temporary accommodation, and a reserve for unexpected costs. If the expected gain is small, targeted repairs may make more sense than a complete renovation.
How to Increase Apartment Value Before Selling
Step 1: Request a Professional Valuation
Establish the apartment’s current market value and identify improvements that may offer a worthwhile return.
Step 2: Identify Defects That May Reduce Buyer Offers
Look for damp, poor ventilation, outdated installations, damaged flooring, or visible maintenance problems.
Step 3: Review PPE Finances and Planned Building Work
Check the renovation fund, upcoming special payments, and projects involving the roof, façade, lift, heating, or common areas.
Step 4: Confirm Permissions Before Starting Renovations
Check the requirements for structural changes, windows, façades, shared systems, or work that may require PPE or official approval.
Step 5: Compare the Renovation Cost With the Expected Value Gain
Include professional fees, permits, temporary accommodation, financing, and a contingency reserve.
Step 6: Choose Neutral Improvements With Broad Appeal
Consider fresh paint, better lighting, practical storage, durable flooring, and functional kitchen or bathroom updates.
Step 7: Keep All Invoices, Warranties, and Approvals
These documents help demonstrate the quality, legality, and maintenance history of the work to potential buyers.
Step 8: Stage the Apartment and Reassess the Asking Price
Improve the apartment’s presentation, update the marketing materials, and obtain professional advice before listing.

Which Apartment Upgrades Add the Most Value?
The best upgrades solve visible problems, reduce future costs, and make daily life easier. They should also match the apartment’s price range and the expectations of local buyers.
1. Repair Defects Before Making Cosmetic Changes
Deal with leaks, damp, mould, damaged flooring, poor ventilation, plumbing faults, cracks, and unsafe electrical systems first.
Fresh paint will not reassure buyers if there is moisture behind the wall. Repairing defects may not transform the apartment, but it protects its value and removes reasons for buyers to negotiate a lower price.
2. Improve the Apartment’s Energy Efficiency
Efficient appliances, heating controls, good ventilation, insulation, and modern windows can lower running costs and improve comfort.
However, windows, façades, roofs, and central heating often form part of the building’s common property. You may need PPE approval before changing them.
Geneva offers support for qualifying energy work through its building energy subsidy programme. Applications generally need to be submitted before work begins. For larger building projects, a CECB Plus audit can compare renovation options, costs, energy savings, and available subsidies.
3. Upgrade the Kitchen Without Overspending
A kitchen renovation can increase apartment value when the current space is damaged or clearly outdated. Yet a full replacement is not always necessary.
Repainting cabinet fronts, replacing worn worktops, updating taps and handles, improving lighting, and adding storage can create a fresher space for less. Choose durable finishes and avoid luxury features that push the kitchen beyond the apartment’s market level.
4. Modernise the Bathroom
Buyers pay close attention to ventilation, waterproofing, seals, lighting, storage, and sanitary fixtures. Small problems can suggest larger maintenance risks.
Replace damaged grout, improve extraction, update taps, and add easy-to-clean surfaces. A practical shower may appeal to more buyers than costly spa-style features. Keep the design simple enough to suit different tastes.
5. Improve the Layout and Storage
Useful space often matters more than decorative space. Built-in storage, defined work areas, and better furniture placement can make a small apartment feel larger.
Be careful with structural changes. Removing walls or moving kitchens and bathrooms may affect load-bearing elements, plumbing, or shared systems. These projects can require technical checks, PPE approval, and official authorisation.
6. Add Light and Neutral Finishes
Fresh paint, consistent flooring, modern lighting, and updated handles can improve an apartment without a major renovation.
Use warm neutral colours that reflect natural light. Remove heavy window treatments and use mirrors carefully in darker rooms. Neutral does not mean empty—the apartment should still feel comfortable and lived in.
7. Improve the Balcony and Entrance
A clean, well-presented balcony can feel like an extra room. Add a small table, suitable plants, or simple outdoor lighting to show how the space can be used.
Keep the apartment entrance bright and uncluttered. Changes that affect the façade or the appearance of the building should be checked against PPE rules before installation.
How Does PPE Condition Affect Apartment Value?
When buyers evaluate a Swiss apartment, they also evaluate the building and its co-ownership structure.
Review the PPE Renovation Fund
Check the renovation fund balance, annual contributions, recent meeting minutes, and any planned special payments. A weak fund may worry buyers because they could face a large bill for future work.
A healthy fund does not automatically increase the formal valuation, but it reduces financial uncertainty and supports buyer confidence.
Check Planned Work on Common Areas
Roof, façade, lift, heating, window, and entrance projects can affect both future costs and apartment resale value. Deferred maintenance may give buyers more room to negotiate.
Before listing, prepare clear information about approved work, budgets, timelines, and how much your apartment must contribute. These are among the main factors that affect apartment resale value.
Get Approval Before Changing Common Property
Owners cannot freely change common building elements or shared systems. Some Geneva renovation projects may also fall under construction rules or the LDTR (Loi sur les démolitions, transformations et rénovations de maisons d'habitation).
The LDTR can affect renovations, transformations, and post-renovation rents for covered housing. Owners of rental apartments should review the official Geneva guidance on LDTR-controlled renovations and rents before starting work.
Which Renovations Offer the Best Return?
There is no fixed return for apartment renovations. The result depends on location, condition, building quality, buyer demand, and the standard of nearby properties.
| Apartment improvement | Potential value impact | Cost level | Main consideration |
|---|---|---|---|
| Repairing defects | High value protection | Low–medium | Complete before cosmetic work |
| Painting and lighting | Strong buyer appeal | Low | Use neutral finishes |
| Partial kitchen refresh | Medium–high | Medium | Avoid unnecessary replacement |
| Bathroom update | Medium–high | Medium | Prioritize function and condition |
| Energy improvements | Strong long-term value | Medium–high | Check PPE and subsidy rules |
| Structural changes | Conditional | High | Confirm demand and permission |
| Luxury personalization | Often limited | High | Not suit future buyers |

Can You Increase Apartment Value Without Renovating?
Deep-Clean and Declutter the Apartment
Remove excess furniture and personal items. Clean the windows, floors, kitchen, bathroom, and balcony. Make the purpose of each room clear.
These steps may not change the appraised value, but they help buyers see the apartment’s size, light, and practical use.
Use Home Staging to Improve Buyer Appeal
Home staging can improve listing photos, viewing experiences, and buyer interest. It can also reduce the chance that poor presentation distracts buyers from the apartment’s strengths.
Use furniture that matches the size of each room. Avoid overdecorating or trying to hide defects.
Prepare the Documents Buyers Need
Prepare floor plans, PPE meeting minutes, renovation fund details, invoices, warranties, permits, charges, energy bills, and certificates where available.
Good records show that the apartment has been maintained properly. They also help buyers and mortgage lenders assess the property with fewer delays.
Are Apartment Renovations Tax-Deductible in Switzerland?
Value-Preserving vs Value-Adding Renovations
Swiss tax rules generally distinguish between value-preserving and value-adding work.
- Value-preserving costs maintain or replace existing elements at a similar standard.
- Value-adding costs improve the property beyond its previous condition.
Their tax treatment can differ by canton and project, so keep detailed invoices that separate each type of work.
Check Energy Grants Before Starting Work
Energy grants may be available for building audits, insulation, heating systems, windows, or other qualifying measures. Some applications must be submitted by the PPE because the work affects the whole building.
Never begin eligible work before checking the application conditions. Starting too early can make a project ineligible for support.
What Changes After 2028?
Switzerland will abolish the imputed rental value system on 1 January 2029. According to the Swiss Federal Department of Finance, federal maintenance deductions for owner-occupied homes will end when the reform takes effect. Federal deductions for energy-saving work will also disappear, although cantons may retain certain energy-related incentives.
For work planned in 2027 or 2028, ask a tax adviser in Geneva, such as Fiduciaire Genevoise, how the timing could affect your situation.
FAQ
There is no single answer for every apartment. Essential repairs, energy improvements, and practical kitchen or bathroom updates often have the strongest effect. Start with the defects or future costs that concern buyers most.
Do not use a universal percentage. Compare the apartment’s current value, expected renovated value, total renovation cost, and likely selling expenses. Spend only when the projected result supports the investment.
No. A new kitchen is more likely to add value when the existing one is damaged or dated. An expensive design may not recover its cost if buyers dislike the style or expect a lower property standard.
You can usually complete minor cosmetic work within your private space, subject to the PPE rules. Structural changes and work involving façades, windows, shared pipes, or common systems may require PPE and official approval.
They can reduce operating costs, improve comfort, and lower the risk of future work. Their effect on resale value depends on the upgrade, building condition, and local demand. Major improvements often need to be handled at PPE level.
Increase Your Apartment’s Value Without Overspending
The best way to increase apartment value is to start with a valuation, repair real problems, and invest in improvements that buyers will understand and use. Consider both the private apartment and the condition of the PPE building before spending.
