Answers from the rulebook for Peterson
Rules another office applies inside Peterson
Peterson does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.
Owner-built residential real estate inside Peterson city limits, under Minnesota residential-contractor licensing law.
Owner must occupy or intend to occupy the property for residential purposes, or retain it for rental purposes upon completion.
The exemption does not apply to construction or improvement for resale or speculation.
An owner constructing or improving more than one property within 24 months is presumed to be acting for speculation unless the properties will be retained for rental purposes.
This is a state contractor-licensing exemption and does not establish an exemption from local permits or other local requirements.
“The license requirement does not apply to: [...] an owner of residential real estate who builds or improves residential real estate”
Septic permitRequired
New or replacement subsurface sewage treatment systems serving property inside Peterson city limits.
The permit requirement applies to new construction and replacement.
A local unit of government may require permits for all or certain repairs.
The official sources reviewed did not identify the particular local unit issuing permits within Peterson.
“Permits must be required for all new construction and replacement.”
Septic inspectionRequired
New construction or replacement of an on-site subsurface sewage treatment system inside Peterson city limits.
The manner and timing of inspection may be determined by the applicable local ordinance.
For a bedroom addition, the local government may temporarily waive the inspection requirement for an application from November 1 through April 30 if inspection occurs by the following June 1 and the applicant submits the compliance or noncompliance document within 15 days.
The bedroom-addition provision does not apply if the local government has no ordinance requiring a building permit for the addition.
“An inspection shall be required for all new construction or replacement of a system to determine compliance with applicable requirements.”
Well permitLimited
Water-supply, dewatering, and environmental wells inside Peterson city limits.
Before construction, the proposed well must generally be reported to the commissioner using the prescribed form and filing fee.
A notification is not required before a temporary boring.
A drive-point water-supply well for farming, agricultural purposes, or the individual's place of abode has a post-construction notification procedure.
The state notification preempts city permits or notifications unless the commissioner delegates authority.
This record identifies a state notification requirement, not evidence of a Peterson well-permit program.
“a person may not construct a water-supply, dewatering, or environmental well until a notification of the proposed well [...] is filed with the commissioner”
Permit processPartial
SSTS construction-permit process for on-site systems inside Peterson city limits.
The applicable local unit of government must review and approve or deny the permit application before issuing the construction permit.
Construction cannot start until a construction permit is granted.
Final approval is evidenced by a certificate of compliance.
This is only the state-required SSTS process; no general Peterson building-permit process was located.
“Construction must not be initiated until a construction permit is granted.”

Each answer was extracted from an official source and independently re-checked against that source by a second reviewer. That is an evidence check, not legal advice. Rules change; confirm with the authority before you buy or build.
Unanswered questions are usually a sign that Peterson publishes no rule on the point, not that none exists. Fillmore County’s page lists the county offices to call.
