Dodge County’s zoning ordinance governs rural, unincorporated areas; each incorporated city has its own ordinance4. Kasson sets zoning inside its city limits; rural septic permitting remains with Dodge County Environmental Services3,9. Rural lot area, depth and width at the structure setback line depend on the applicable primary or overlay district, and the parcel must also accommodate the proposed use, setbacks and sewage-treatment areas5. The 53-acre Agricultural District threshold determines whether a dwelling needs interim-use approval; it is not a blanket minimum lot size1. Certain townships may impose additional requirements for particular uses1. We could not confirm the complete setback schedule, minimum dwelling size or accessory-dwelling rules; ask Environmental Services — Zoning about the parcel’s district2.
How do septic permits work in Dodge County?
Dodge County Environmental Services handles rural sewage-treatment permits, and a licensed septic designer must prepare the design.
Dodge County Environmental Services handles rural sewage-treatment permits, and a licensed septic designer must prepare the design1,3. A newly created parcel must support two Type 1 sewage-treatment systems, with the primary and reserve drainfields protected from construction and other land disturbance1. A new system needs county approval before construction, and the installer must notify Environmental Services 24 hours before construction for an inspection3. Soil feasibility deserves early attention: only about 1.9% of Dodge County soils are rated without severe limitations for a conventional drain field, so budget for site evaluation and the possibility of a nonconventional design10. Call the department before the designer completes the soil evaluation because the county coordinates onsite soil verification3.

Minnesota treats the State Building Code as the construction standard for tiny houses, while local zoning determines whether a tiny house or accessory dwelling is allowed on a parcel12,13.

- A rural dwelling, accessory structure or addition needs its own zoning permit even though Dodge County does not administer the State Building Code1.
- RV living, tiny-home occupancy and minimum dwelling size remain unconfirmed; ask Dodge County Environmental Services — Zoning about the exact parcel and proposed use2.
