Onsite wastewater systems are regulated through local public health and permitting authorities; permit review typically covers site evaluation, soil testing, system design and installer qualifications. Before installing or altering a system, obtain written approval and required permits; failure to do so can delay occupancy or sale.

Inspections, approvals and common violations

Inspections typically occur after excavation and after installation but before backfill, and again for final approval. Common violations include installing without a permit, incorrect system sizing or location, and failure to follow approved designs. Remedies often require corrective work, re-inspection and additional fees.

  • Pre-installation inspection and site approval.
  • Mid-construction inspection before covering drainfields.
  • Final inspection and certificate of compliance or occupancy conditions.
Keep copies of permits, designs and inspection reports for property transactions.

Action steps for homeowners

  • Confirm which authority issues the permit for your property and request site evaluation.
  • Hire a qualified designer or installer and submit the complete application package.
  • Schedule required inspections and do not backfill until approved.
  • Pay applicable fees and obtain the final compliance document before occupancy.
Document every inspection and approval to avoid issues when selling the property.
