Insurance for a Residential Service Business
Overview
Most service-business owners under-insure. They have liability coverage but don't understand what it actually covers. They have a commercial vehicle policy but didn't realize their employee's accident isn't fully covered. The discovery happens when a claim hits + the insurance doesn't pay. This reference covers what you actually need.
Required insurance types
General Liability (GL):
Covers: third-party bodily injury + property damage from your work Minimum: most residential service businesses carry a per-occurrence limit with a higher aggregate cap on top, set by what a single serious claim (a house fire, a flooded floor, a fall) could plausibly cost Typical premium: a modest annual line item relative to revenue for most residential service business
When you need it: every job, every customer. Without it, one negligence claim ends the business.
Workers Compensation:
Covers: employee injuries on the job (medical + lost wages) Required by law in most states for businesses with employees
Even if you're the only employee, some states require it. Sole-proprietors are usually exempt but it's worth carrying anyway for liability protection.
Commercial Auto:
Covers: company-owned vehicles + non-owned vehicles used for business Personal auto policy DOES NOT cover business use; you need a commercial policy
If techs use their own vehicles for service calls, you still need NON-OWNED commercial auto coverage; their personal insurance won't pay if they injure someone on the job.
Tools + Equipment / Inland Marine:
Covers: your tools, parts, equipment in trucks + at job sites Standard commercial insurance often excludes tools from work - Inland Marine fills the gap
Worth carrying once your tools + equipment on hand represent a meaningful replacement cost; a stolen truck full of tools is a common claim, not a rare one.
Errors & Omissions (E&O) / Professional Liability:
Covers: financial damages from your professional advice More relevant for: engineering work, consulting, inspections (e.g., termite inspectors), specifications, design work
Less relevant for: standard residential repair work (GL covers most of that)
Cyber Liability:
Covers: data breaches, lost customer data, ransomware Increasingly important - most service businesses have customer data online
Premium is typically a small line item for a residential service business relative to the exposure it covers.
Umbrella / Excess Liability:
Covers: above the limits of GL + Auto + others Adds a substantial multiple of your underlying coverage at relatively low cost
When you've got significant business assets to protect, an umbrella is essentially mandatory.
What insurance does NOT cover
Intentional acts: if you intentionally damage something, insurance doesn't pay.
Pre-existing conditions: insurance doesn't pay for losses that started before the policy.
Liability beyond policy limits: if a claim exceeds your policy's limit, the shortfall is yours to cover personally.
Punitive damages: generally not covered.
Pollution: standard policies exclude (specialty pollution coverage needed for certain trades).
Mold: often excluded; specialty endorsements available.
Asbestos / lead: standard exclusions; specialty coverage needed.
Common insurance mistakes
Mistake 1: Insufficient liability limits.
The bare state-minimum limit is rarely enough. For most residential service businesses, a meaningfully higher limit is appropriate given what a serious claim can actually cost. The premium difference is small; the protection difference is large.
Mistake 2: Coverage gaps.
Some policies exclude things you'd assume are covered. Read your policy. If you can't explain what's covered + excluded to a customer, you don't actually know.
Mistake 3: No certificate management.
Customers (especially commercial) request "Certificates of Insurance" (COIs). Some require being added as Additional Insured. If your insurer doesn't generate these promptly, you lose work.
Mistake 4: Sole-proprietor without workers comp.
If you're a single-owner business without workers comp, you have NO coverage for your own injuries on the job. Health insurance might cover medical; lost income is on you.
Mistake 5: Personal vehicle for business use.
Your personal auto policy excludes business use. One accident during a service call = no coverage. Get commercial auto.
Certifications + endorsements that affect insurance
- OSHA certifications: some policies offer discounts
- Industry-specific certifications: NATE for HVAC, etc.
- Safety training: documented programs reduce premiums
- Background-checked technicians: insurance discounts in some markets
How to shop for insurance
- Use an independent agent (not a direct insurer). They can quote multiple carriers.
- Compare apples to apples - same limits, same coverages, same deductibles
- Read the policy before signing, not after
- Annual review - coverage needs change as the business grows
- After any claim - review coverage; consider if you need more
- Industry-specific carriers often have better products than general commercial carriers
Typical residential service business insurance cost
For a small-to-mid business, expect a mix like this:
- General Liability: the single largest line item of the core policies, scaled to revenue + claims history
- Commercial Auto: priced per vehicle, varies with driver record + vehicle type
- Workers Compensation: 3-8% of payroll
- Inland Marine: modest, scaled to tool + equipment value on hand
- Umbrella: relatively cheap for the amount of extra coverage it adds
Total typical annual insurance cost: 1-3% of revenue.
NEVER let your insurance lapse. A 30-day gap means: customer issues from work done during the gap are NOT covered + many insurers won't renew you afterward + your premiums when you re-apply are significantly higher. Set up auto-pay; set calendar reminders for renewal.
