5 Insurances for Homebuilders & what you need to pay attention to
When building a house, it’s about six- to seven-figure sums — and about risks that many homeowners completely underestimate. Delays, fire at the raw construction site, a child getting hurt on an unsecured construction site, or a construction helper falling from a ladder: Even a single uninsured damage can derail the entire financing. Anyone building a house is liable as the homeowner in many cases regardless of fault — and that’s exactly why the right insurance before the first shovel is dug is a must, not a luxury. Here you will find the five most important homeowner insurances with cost ranges, coverage amounts, a comparison table, and a checklist.
Insurances for house construction – Your protection against six-figure risks
The fact that homeowners are generally liable for damages and accidents on the construction site — often regardless of actual fault — is unknown to most. The so-called duty of traffic safety makes you, as the homeowner, responsible for everything that happens on your “construction site.” A personal injury resulting in permanent disability can quickly cost between 1 and 5 million euros. Which insurances are actually sensible is shown in our overview of Real Estate Insurance — and additionally, a look at the entire additional costs real estate purchase is worthwhile, as insurance premiums often get overlooked in the financing plan.
The 5 Most Important Homeowner Insurances at a Glance
| Insurance | What is covered | Mandatory? | Annual cost approx. | Recommended coverage |
|---|---|---|---|---|
| Builder’s liability insurance | Personal and property damage to third parties | De-facto mandatory | 80–250 € | min. 5–10 million € |
| Fire and shell construction insurance | Fire, lightning, explosion during shell construction | Bank usually requires | 0–150 € (often free first year) | Full construction value |
| Construction work insurance | Storm, theft, vandalism, construction defects | Optional, strongly recommended | 200–600 € | Full construction value |
| Helper accident insurance + BG BAU | Injuries to unpaid helpers | BG BAU = mandatory! | BG BAU from 100 €/helper/year | Legally regulated |
| Land liability insurance | Damage on undeveloped land | Optional | 30–80 € | min. 3 million € |
Builder’s liability insurance – Protection against personal injuries
Although your private home is usually built by a third-party company, as the homeowner you personally are liable for damages caused by the construction site. If the excavation is not adequately secured, a child falls in and suffers permanent damage, you are liable — even if the construction company messed up the safety measures. Personal injuries with long-term consequences can quickly reach damage sums of 1 to 5 million euros.
What private liability insurance does NOT cover
A standard private liability insurance policy covers construction projects up to a building sum of about 50,000 euros — suitable for minor renovations, completely insufficient for a new build. Those who do not top this up are personally liable with their private assets in the event of damage.
What to look for in homeowner’s liability insurance
- Insurance coverage: at least 5 million euros for personal and property damage — for higher-value construction projects, ideally 10 million euros
- Duration: until the building is completed and ready for occupancy, ideally with an automatic transition into private liability insurance
- Own work covered: important if you are doing some of the work yourself
- Transport safety obligation: explicitly included
- Construction failure due to insolvency of the construction company — not included in every policy
The contributions vary depending on the construction amount and provider between 80 and 250 Euro for the entire construction period. In relation to the potential damage, an insignificant amount — and therefore essential for every project around Buy a house and new construction.
Fire rough construction insurance – the mandatory policy of banks
As house construction takes several months, the unfinished rough construction is constantly exposed to fire hazards: welding work, drywall work, faulty construction dryers, lightning strikes or arson. A fire at the rough construction stage can mean total loss in the worst case — and you continue to pay the loan without a house.
When the building insurance applies – and when it does not
The standard building insurance only kicks in once the property is habitable. For the period before that, you need fire and raw construction insurance. Practical: Many insurers offer it for the first 12 to 24 months free of charge, if you commit to taking out the building insurance with the same provider afterwards.
Why the bank demands this insurance
Banks usually make the disbursement of the construction loan dependent on a concluded fire and raw construction policy — after all, the raw construction is the security. Anyone who doesn’t want to endanger their real estate financing concludes the policy before the first disbursement date. This is especially true with the current building interest rates — banks have become stricter in their risk assessment.
Construction performance insurance — protection against storms, theft and faulty work
The construction work insurance is the all-risk insurance for house building and complements the fire and shell construction policy. It covers all damages that DO NOT result from fire:
- Storm and hail damage to the shell construction
- Flood, heavy rain, landslides (often as an elemental building component)
- Vandalism and burglary — theft of building materials is a mass phenomenon on construction sites
- Construction and material defects up to the acceptance
- Frost damage during winter construction
- Misconduct of construction helpers (damaged building components)
Typical damage examples from practice
A storm tears off the newly roofed roof: 30,000 to 80,000 euros. Thieves steal copper pipes and heating technology from the shell construction: 10,000 to 25,000 euros. Heavy rain floods the floor slab before the shell is closed: 15,000 to 50,000 euros in drying and renovation costs. The annual premium is between 200 and 600 euros — a fraction of a single damage incident.
Construction helper accident insurance – Attention: BG BAU is mandatory!
Here lies the biggest mistake made by many homeowners: Anyone who uses friends, family, or acquaintances for interior renovations is legally obliged to register all construction helpers with the German Social Accident Insurance for the Construction Industry (BG BAU) within one week. Anyone who forgets to do this risks fines of up to 2,500 euros — and in the event of damage, significant liability.
BG BAU vs. private helper’s accident insurance
- BG BAU (Mandatory): Premium of around 1.80 euros per helper hour, at least about 100 euros per helper and year. Covers medical treatment, rehabilitation, and pension in case of permanent disability — BUT only the statutory minimum benefits.
- Private helper’s accident insurance (Supplement): Covers pain compensation, disability sums, death benefit, and daily allowance. Premium from about 80 euros per helper.
Which helpers must be registered?
Even unpaid helping relatives and friends must be reported — exception: spouses and registered life partners. Anyone who builds without registration and a helper gets seriously injured is personally liable as the builder for medical treatment and pension costs in the range of six to seven digits. Anyone who wants to buy their first property and uses helpers should complete the BG-BAU registration on the very first day.
Liability insurance for plots – mandatory from the transfer of ownership
Before construction can begin, the right plot must first be found, financed, and registered in the land register. Anyone who knows the specifics of selling a plot knows: With the land register entry, your duties as an owner begin — even if the plot remains vacant for months.
Safety obligations on unbuilt plots
- Winter service: Clearing and salting of adjacent sidewalks
- Tree inspection: Remove rotten branches and sick trees
- Fencing: For excavation sites, pits or hazardous areas
- Traffic safety: Lying construction debris, open shafts
If someone gets injured on your plot, you are liable. In case of a construction delay of several months or construction during winter, liability insurance for the plot is mandatory at 30 to 80 euros per year. Tip: Often it is already included in the builder’s liability insurance from the start of construction — check before finalizing, otherwise you might end up paying double.
Elemental damage protection – the growing risk
Floods, heavy rain and backflow have become one of the most expensive construction and housing risks in recent years. Standard policies often exclude elemental damage. Homebuilders should definitely check:
- Is the plot located in ZÜRS zone 3 or 4 (high flood risk)?
- Does the construction and later building insurance offer an elemental damage component?
- How high is the deductible in the elemental case (often 10 % of the damage, at least 500 €)?
The surcharge varies depending on the risk zone between 50 and 400 euros per year — a single water damage incident can quickly cost 50,000 euros and more.

Compare insurance – what really matters
Even though insurance coverage may look similar, premiums and clauses can differ significantly in the fine print. Anyone who wants to save hundreds of euros when Buy real estate or building should check the following comparison criteria:
- Sum insured: check not only the standard option, but also the maximum option
- Deductibles: 0 €, 250 €, 500 € — affects the premium by 15–30 %
- Gross negligence: is it covered or excluded?
- Combination discounts: builder’s liability insurance + construction work from the same provider often saves 10–20 %
- Provider type: direct insurers are often cheaper, while independent real estate agents offer individual clause optimization
