What is Supplemental Building Questionnaire?
A Supplemental Building Questionnaire (SBQ) is a form used by insurance companies to gather additional details about a building or structure beyond what’s collected in a standard property insurance application. It helps assess unique features, construction details, occupancy, and potential risks that may affect coverage decisions and premiums.
Who Needs It
Property owners, especially those with commercial buildings, multifamily dwellings, or specialized structures, may be asked to complete an SBQ. Insurance agents or underwriters typically request it when a building has characteristics that require closer evaluation, such as older construction, mixed-use occupancy, or high-value features.
What It Typically Covers
While the exact format varies by provider, most Supplemental Building Questionnaires include questions about:
- Year built and major renovations
- Construction type (e.g., wood frame, masonry, steel)
- Roof type and age
- Fire protection systems (sprinklers, alarms)
- Heating, plumbing, and electrical systems
- Occupancy details (residential, commercial, number of tenants)
- Security features (locks, surveillance, building access)
Common Exclusions and Limitations
Completing an SBQ helps insurers determine if there are conditions that could limit coverage. For example, buildings with outdated electrical systems, lack of fire suppression, or unpermitted additions may face exclusions or require special endorsements. The questionnaire itself does not grant or deny coverage—it informs underwriting decisions.
Factors That Influence Cost
While the SBQ doesn’t set rates directly, the information it gathers can affect the cost of your property insurance. Elements that may influence pricing include:
- Building age and structural integrity
- Risk mitigation systems in place
- Occupancy type and tenant behavior
- Location and surrounding hazards
Proof of Insurance & Compliance
Some municipalities or lenders may require an SBQ as part of their compliance or risk assessment process. Insurance carriers may also keep it on file to support underwriting decisions. Requirements can vary by state and property type, so it's important to coordinate with your agent or broker.
