Complos · May 14, 2026
End-to-end guide to FL HB 1379 (the 2023 BMAP statute), HB 1417 (annual operating-permit inspections), the July 2030 upgrade cliff, FDEP audits, BMAP zones, Save Our Lagoon-style grants, and nitrogen-reducing approved systems.
Florida HB 1379 BMAP Compliance for Septic: The Complete Guide
By The Complos Team. Last reviewed 2026-05-14.
TL;DR. Florida HB 1379 (2023) sets a July 1, 2030 cliff for septic upgrades on ~2.6 million properties inside designated Basin Management Action Plan (BMAP) zones. Conventional septic must be replaced with FDEP-approved nitrogen-reducing systems. HB 1417 (effective 2026) layers annual operating-permit renewals on top. FDEP audits 25% of inspection reports. The cost runs $7K–$25K per property; multiple grant programs exist for impaired-watershed parcels.
This pillar guide indexes every FL-focused article. The MA-side guide is at the MA Title 5 inspection complete guide; FL operates under a parallel but distinct statutory framework rooted in F.S. 381.0065 and 62-6 F.A.C..
The regulatory layers
| Layer | Statute / rule | What it controls |
|---|---|---|
| F.S. 381.0065 | Statute | Onsite sewage treatment + disposal systems (the FL Title 5 equivalent) |
| 62-6 F.A.C. | Rule | FDEP implementation: setbacks, sizing, materials, inspector cert |
| HB 1379 (2023) | Statute | BMAP-zone upgrade cliff, nitrogen-reducing system requirement |
| HB 1417 (2026) | Statute | Annual operating-permit inspections for BMAP-zone systems |
HB 1379 is the cliff. HB 1417 is the recurring obligation that keeps the cliff effective.
The 2030 cliff: who's affected
The 2030 roadmap article breaks down the upgrade timeline. The 30-second version:
- Inside a BMAP zone + conventional septic system = must upgrade to nitrogen-reducing system by July 1, 2030
- Outside a BMAP zone = state floor under 62-6 F.A.C. applies; no HB 1379 cliff
- Inside a BMAP zone + already on nitrogen-reducing system = HB 1417 annual inspection cycle starts 2026

What an HB 1379 upgrade looks like
Nitrogen-reducing approved systems guide covers the FDEP-approved system list. The common types:
- Aerobic Treatment Units (ATU) with nitrogen reduction
- In-ground performance-based treatment systems (PBTS)
- Drip-irrigation distribution upgrades to existing AB systems
- Sewer connection where municipal service is available within 200 ft
Cost range:
| Upgrade type | Typical cost (2026 FL) |
|---|---|
| ATU replacement | $9,000–$15,000 |
| PBTS retrofit | $12,000–$22,000 |
| Drip-irrigation upgrade | $7,000–$11,000 |
| Sewer connection (if available) | $5,000–$25,000 (depends on lateral run) |
HB 1417: the annual inspection cycle
FL FDEP BMAP inspection cycle covers the recurring obligation. Each BMAP-zone system needs:
- Annual operating-permit renewal filed with FDEP
- Inspection report from a Florida master septic contractor (cert details: FDEP master installer renewal + FL septic contractor renewal)
- Audit-readiness package in case the parcel is one of the 25% sampled by FDEP — see the annual BMAP inspection guide
Grants + assistance programs
FL septic-to-sewer conversion grant covers the major programs:
- DEP Wastewater Grant Program (matches 50% of upgrade cost for low-income owners)
- Save Our Lagoon-style local programs in Indian River Lagoon counties
- USDA Rural Development loans for rural parcels

Frequently asked questions
What happens if I don't upgrade by July 1, 2030?
Under HB 1379, properties inside a BMAP zone that haven't upgraded by the cliff date become non-compliant. FDEP can issue notices of violation; counties can deny building permits or change-of-use applications until the upgrade is complete. Practical buyer's reaction: cliff-adjacent listings already see 8–15% price haircuts.
Does HB 1379 apply to properties on sewer?
No — only to properties on onsite (septic) systems. If sewer is available within 200 ft, HB 1379 prefers connection over upgrade.
Who inspects HB 1417 annual renewals?
Florida master septic contractors with current FDEP certification. The contractor files the inspection and renewal package; the owner is responsible for scheduling and paying.
Is Complos approved by FDEP?
Complos is independent compliance software — it generates inspection reports that meet FDEP audit format. There is no "FDEP approval" of compliance software; the FDEP-certified contractor remains the licensed party.
