What Is a BMP Maintenance Agreement?
A BMP maintenance agreement is a legally binding document recorded with the county that requires a property owner to inspect, maintain, and repair stormwater best management practices (BMPs) on their property. It's created during the development permitting process, signed by the developer and the local municipality, and runs with the land permanently, meaning it transfers to every future owner automatically.
Why BMP Maintenance Agreements Exist
When a property is developed, the developer is required to build stormwater BMPs (retention ponds, detention basins, bioswales, etc.) to manage runoff and protect water quality. But the municipality needs assurance that these systems will continue to function long after the developer moves on to the next project.
The maintenance agreement solves this problem. It creates a permanent legal obligation tied to the land, not to any individual person or company. Whoever owns the property owns the maintenance responsibility. This mechanism is required under MS4 permits in South Carolina (SCDES), Georgia (GA EPD), Florida (FL DEP), and North Carolina (NC DEQ).
What a Typical Agreement Includes
While the exact language varies by municipality, most BMP maintenance agreements contain these sections:
- BMP identification. A list of every stormwater facility on the property, including type (wet pond, dry basin, bioretention, etc.), location, and design specifications.
- Inspection requirements. How often each BMP must be inspected (typically annually) and who is qualified to perform inspections.
- Maintenance responsibilities. Specific tasks required for each BMP type, including mowing schedules, sediment removal thresholds, structural repair standards, and vegetation management.
- Reporting requirements. When and how inspection reports must be submitted to the municipality.
- Access provisions. A clause granting the municipality the right to enter the property and inspect BMPs at any time, with or without prior notice.
- Enforcement provisions. What happens if the property owner fails to comply, including the municipality's right to perform maintenance and bill the property owner, assess fines, or place liens.
- Covenant running with the land. Language making clear that the agreement transfers to all future owners automatically.
Who Signs the Agreement
The agreement is signed by the current property owner (initially the developer) and the local municipality or stormwater authority. It's then recorded with the county Register of Deeds or Clerk of Court, making it a matter of public record attached to the property's chain of title.
For HOA communities, the agreement is typically signed by the developer before any lots are sold. When the developer turns over control of common areas to the HOA, the maintenance obligations transfer automatically. The HOA doesn't need to sign a new agreement; the existing one already binds the property regardless of ownership changes.
Consequences of Non-Compliance
Failing to comply with a BMP maintenance agreement can trigger several consequences:
- Municipal self-help. Most agreements give the municipality the right to enter the property, perform the required maintenance, and bill the costs back to the property owner, often with administrative surcharges of 25-50%.
- Liens. Unpaid maintenance costs and fines can be placed as liens on the property, affecting the owner's ability to sell or refinance.
- Fines and penalties. Municipalities can assess fines under their stormwater ordinances, often $100 to $1,000 per day for ongoing violations.
- Permit revocation. In extreme cases, the municipality can revoke the property's stormwater permit, which can halt construction activity and block occupancy permits for new buildings.
What to Do If You Can't Find Yours
If you're unsure whether your property has a BMP maintenance agreement, or if you can't locate a copy, start with your local stormwater utility or municipal engineering department. They maintain records of all maintenance agreements within their jurisdiction. You can also search the county recorder's online database using your property address or subdivision name. Any property developed after the mid-1990s with on-site stormwater BMPs almost certainly has a recorded agreement.

Where can I find my BMP maintenance agreement?
BMP maintenance agreements are recorded with the county Register of Deeds (or Clerk of Court in some states). You can search by property address, subdivision name, or parcel number. Your local stormwater utility or municipal engineering department can also provide copies. In many cases, your HOA management company or property manager should have a copy on file from closing or developer turnover.
Can a BMP maintenance agreement be modified?
Yes, but it requires approval from both the property owner and the municipality. Modifications might be needed when BMPs are redesigned, replaced with different types, or when the property is subdivided. The modified agreement must be recorded with the county, and the municipality will typically require engineering documentation supporting the change.
What's the difference between a maintenance agreement and a stormwater permit?
A stormwater permit (like a CGP or MS4 permit) is a government-issued authorization for specific activities like construction or stormwater discharge. A maintenance agreement is a recorded covenant that obligates the property owner to maintain stormwater BMPs in perpetuity. Permits expire and must be renewed. Maintenance agreements run with the land forever and survive property sales, management changes, and ownership transfers.
