Answers from the rulebook for Fenton

Fenton’s own rules

  • Building permitRequired

    Structural work and new construction inside Fenton city limits, issued by the City's building division (Protective Inspection)

    • The guide's two-column list is flattened in the PDF text; the items listed (structural changes, demolition, accessory structures over 200 sq ft, decks, roofing, pools, additions, new structures, window replacement, residing) are the 'required' column per the page heading.
    • A zoning permit is separately required for accessory structures regardless of size, and for other listed items.
    • Owners may apply for work on their own residence; builders must be licensed with the State of Michigan.
    • Fees and application forms were not on the PDF; contact the building division at (810) 629-2261 to confirm whether a permit is needed.
    “all work involving structural changes (roof framing, enlarging windows, interior remodeling or floor plan changes)”
  • Owner-builder exemptionConditional

    Owners doing work on their own residence in Fenton city (permit applicant eligibility, not a licensing exemption)

    • Page states owners may apply for work on their place of residence; it does not state a state-law licensing exemption.
    • Builders must be licensed with the State of Michigan to apply.
    • State construction-code licensing rules were not separately verified.

    “the city is hereby divided into the following zoning districts”

    Zoning districts of Fenton city

    • District list is published in the ordinance text; the zoning map (Sec. 3.02) is adopted by reference but no online map was located on the official site.
    “the city is hereby divided into the following zoning districts”
  • Minimum dwelling sizeSpecified

    Multiple-family dwelling units in Fenton city (not single-family homes)

    • Unit sizes were read from a flattened PDF; the size-to-unit-type mapping (efficiency, 1, 2, 3 bedroom) is inferred from layout and should be checked against the footnote.
    • Single-family minimum dwelling size is not stated in the schedule text reviewed.

    minimum floor area, efficiency unit: >= 450 square feet (multiple-family units) · minimum floor area, 1-bedroom unit: >= 700 square feet (multiple-family units) · minimum floor area, 2-bedroom unit: >= 850 square feet (multiple-family units) · minimum floor area, 3-bedroom unit: >= 1000 square feet (multiple-family units)

  • Minimum lot sizeDistrict specific (with conditions)

    Single-family districts in Fenton city: rural density residential (RDR) and low density residential (LDR), each set by the Table 15.1 schedule

    • The PDF text flattens Table 15.1, so the per-district numeric minimum lot area could not be reliably matched to RDR and LDR columns and is not stated here.
    • Verify the RDR and LDR values in the table itself before use.

Unanswered questions are usually a sign that Fenton publishes no rule on the point, not that none exists. Genesee County’s page lists the county offices to call.
