Indoor Air Quality Assessments in Saint John, NB
Whether you hold a single rental in Saint John or manage a portfolio across New Brunswick, indoor air quality assessments follows the same logic: know what applies, document what you do, and use qualified people.
Indoor air complaints — headaches, odours, stuffiness, symptom clusters — are where building operations meet health claims, and they escalate badly when answered with reassurance instead of measurement. A structured IAQ assessment measures what matters, ties findings to the ventilation system actually delivering (or not delivering) air, and produces a report that stands up with tenants, employees and regulators.
How it works in New Brunswick
Jurisdiction matters: in New Brunswick, the National Building Code as adopted under the Building Code Administration Act governs, and the power to inspect, approve or prosecute rests with the municipality together with Residential Tenancies Tribunal. We scope every job against their current requirements.

What makes Saint John specific: the uptown’s brick heritage blocks and Canada’s oldest continuously occupied housing stock keep facade, fire escape and hazmat files constant, and the city enforces a vacant building program.
Typical Saint John clients for this service: landlords answering municipal or insurer letters, buyers in due diligence, condo boards keeping their statutory calendar, and business owners fitting out or renewing leases.
Workplace duties
Provincial occupational health regimes require employers to maintain acceptable indoor air, and joint health and safety committees can compel investigation of complaints. An independent assessment against ASHRAE 62.1 and Health Canada residential guidance is the standard, defensible response.
