For a new home with an on-site septic system in Chisago County, Minnesota, first ask whether Environmental Services received the installed-system as-built record. The County’s New Home Building Permit Checklist requires that drawing before it issues a Certificate of Occupancy (CO). The septic design submitted with the permit application answers what was planned; the as-built shows what was installed. Neither a design approval nor a scheduled building final proves that the as-built reached the County or that a CO was issued.
Follow the design, installation and occupancy records
The County’s checklist asks for a percolation test, site information and septic-system design with the application. Later, before CO, it asks for the installer’s as-built drawing of the system serving the dwelling. Its separate Inspections page calls this an “As Built Record,” says the office must receive it, and says a CO is issued upon the owner’s request. These statements apply to a building with on-site septic; they should not be copied onto an address served by a different wastewater arrangement without checking the permit.
Use a short record log instead of one “approved” box:
- Design and septic permit: record the proposed system drawing, permit number and approval date. This identifies the authorized installation but is not a record of the installed layout.
- Installed-system as-built: ask for the completed, signed as-built and confirmation of County receipt. The County publishes a blank installer form with fields for site address, permit number and parcel ID. A blank form shows what information is requested; it is not evidence that a particular system was built or accepted.
- Building final and CO: request the final inspection result for the matching building permit and the issued CO, if any. The County’s Inspections page also discusses the posted energy certificate and blower-door test before occupancy. A completed septic drawing does not itself show the building final passed.
If you have a design but cannot locate an as-built, ask the installer or County which completed drawing was submitted and when. If a document is in a portal account, identify whether that is the application’s own file or a generally accessible record; the County does not promise an anonymous public search of every septic as-built. A blank result in one view does not prove the County never received the drawing. Our no-result search guide explains that limit, while the final inspection status guide helps keep the final building result separate.
What a complete Chisago County new-home file should contain
The County’s checklist says it won’t accept a new-home application unless every item is presented together. That gives you a list of documents to expect in the original permit file, and to ask about by name:
- Septic design package: two copies of a percolation test with 2 percolation holes and 4 deep soil borings, a site plan and the septic design, prepared by a Minnesota-licensed person who is a disinterested party. The County then verifies the soils on site. The checklist notes homeowners may install their own system, so the as-built may come from the owner rather than a licensed installer.
- Stamped house plans: two complete sets; the building official returns one with corrections, and it must be posted on site. Houses within city limits also need an 11 x 17 plan.
- Parcel proof: a deed and tax parcel number, or for a newly split parcel, a recorded deed showing the division. Surveys are required for all building within cities and Lent Township.
- Address assignment: the County assigns the address as the permit is processed, with a 911 sign fee of $75 to $225 in most areas. A new home’s address may first appear on the permit itself.
- Driveway access: an approved township or County access permit. In Shafer, Rushseba and Franconia townships, building permits on township roads aren’t issued until the township approves the installed driveway, so that approval should predate the building permit.
Before the CO, the County also requires the posted Energy Code Compliance Certificate with an attic insulation card, and a blower door test. If you’re checking a finished house, those are three more items that should sit in the file next to the septic as-built.
Request the actual County file
The checklist and Inspections page direct questions to Chisago County Environmental Services/Zoning, 313 N Main Street, Suite 240, Center City, 651-213-8370. Ask for the as-built tied to the site address, septic permit number or parcel ID, plus the matching building final and CO if those are the records you need. Explain whether you want to inspect the filed drawing, obtain a copy, or learn whether the County received it. Do not ask the septic installer for a new drawing when the question is which document the County already holds.
If ordinary department contact does not supply the copy, the County’s Data Practices Request page for data not about the requester gives a written-request or disclosure-form route to the responsible authority. Describe the existing records sought: the filed as-built, septic permit or inspection record, building final, and issued CO for the identified property and period. The County explains that a data request seeks records rather than asking staff to answer an open-ended question. Release depends on how the County classifies the data.
Do not confuse a current septic compliance certification with the original new-home as-built. The County’s Point-of-Sale Requirements page describes a separate certification/inspection route and account-retained records. That can answer a later system-condition question, but it is not automatically the original installer drawing.
