Part II: Pre-Purchase Preparation
3. Evaluating the Developer and Project
Buying off-plan means putting significant trust in the developer’s ability to deliver on time, within budget, and to the promised quality. In Switzerland, construction quality varies greatly between developers, and problems can arise even with large, well-known names. This section explains how to research a developer before signing.
3.1 Understanding the Developer’s Track Record
Construction quality, customer service, and responsiveness to defect claims can vary significantly — even among well-known developers.
- Check local news archives for disputes, court cases, or large-scale defect claims involving the developer.
- Ask whether the same general or total contractor (see Section 1.2) will be used — subcontractor networks often determine real build quality.
- Even if the developer is solvent, key subcontractors (e.g., kitchen, bathroom, or façade suppliers) can go bankrupt during construction, causing delays and uncertainty about defect liability.
3.2 Typical Project Timeline
Swiss off-plan apartment projects often follow a predictable sequence, but exact timings vary depending on the developer, canton, and sales progress.
-
Land acquisition and permitting – The developer secures the land and applies for a building permit (Baubewilligung / Permis de construire).
- Building permits (and even permit applications at the Submission stage) are usually publicly accessible at the cantonal or municipal level. Examples: Baugesuch viewer[1] in Canton Zurich, E-bau publikationen[2] in Canton Schwyz.
- On Huusli, construction permit information is automatically linked to a project where available, so you can see the permit status without searching separate canton portals.
- Developers cannot start construction until the permit is legally valid (after any appeal periods).
-
Pre-sales phase – Many developers require 40-60% of units sold before construction begins.
- This is often a bank financing condition to reduce risk before releasing full construction loans.
- In this phase, delivery dates are often tentative or not specified at all, since they depend on reaching the sales threshold.
-
Construction start – Once financing is secured, groundwork begins (site preparation, excavation, foundations).
- A provisional delivery date is usually set at this point, often 18–24 months ahead.
-
Structural completion (Rohbau / gros œuvre) – The main structure is finished; roof and windows installed (“topped out” stage).
- Payment milestones may trigger here under staged-payment contracts.
-
Interior works – Electrical, plumbing, insulation, plastering, floors, kitchens, and bathrooms are installed.
- Buyer customisations (tile choice, kitchen upgrades) happen during this period.
-
Final works and inspection – Common areas completed, landscaping done, technical systems tested.
- The handover date is fixed and invitations for inspection are sent.
-
Handover & occupancy – Formal transfer of keys and signing of the handover protocol (Abnahmeprotokoll / procès-verbal de réception).
- Discussed later in the Room-by-Room Technical Inspection section.
Timelines slip quite often.
The most common causes of delay are slow pre-sales, permitting appeals, subcontractor insolvency, and supply chain issues for materials like windows or tiles.
3.3 Red Flags in Marketing Material and Contracts
Watch for:
- Overly generic specifications (high-quality finishes, Swiss-made) without brand or model references.
- Clauses excluding the developer’s liability if a subcontractor (e.g., kitchen or bathroom supplier) goes bankrupt during construction — which can leave you chasing an insolvent company for defects.
- Aggressive pre-sale discounts with short deadlines — often a sign of cashflow pressure.
A Tages-Anzeiger report reported that buyers avoided one development after discovering that sales contracts excluded developer liability for all works and shifted them to the individual contracting companies.
Subcontractor bankruptcy
Under Swiss law (Art. 367 CO), if your contract is with a general or total contractor, they remain liable for defects even if a subcontractor (like the kitchen supplier) goes bankrupt — unless your contract explicitly excludes this.
If liability is excluded, you may have no recourse other than pursuing the insolvent subcontractor. Use Huusli sales contract checker to analyze your contract and check for potential red flags.
3.4 Practical Recommendations
- Visit past projects by the same developer (from their website, press releases, or online searches).
- Inspect public areas such as facades, balconies, staircases, entrance doors, and landscaping for signs of premature wear or poor workmanship.
- If you meet residents outside or in common areas, politely ask if they are satisfied with the build quality and after-sales service.
- Community outreach: Search local Facebook groups, neighborhood/reddit forums, or online classifieds for owners of that development. These forums often surface issues like recurring defects, delays, or lack of responsiveness that may not be visible in official channels.
- Hire an independent construction expert (Bauleiter, expert en construction) to review plans and specifications before signing.
- For projects already underway, arrange site progress checks to ensure that materials and methods match contract descriptions.
- Have the expert attend handover to document visible defects for the warranty protocol
When you visit a completed development, common areas often reveal quality issues more reliably than model apartments.
Look at facades, staircases, doors, and balconies — they age faster and expose construction shortcuts.
