Zoning, building permits and septic rules in Watertown Township, Michigan

Watertown Township’s own rules

• Local zoningPresent (with conditions)

  Land inside Watertown township's limits (Sanilac County, Michigan), administered under the township's own Zoning Ordinance No. 200. Not applicable to the county's unincorporated area.

  • The ordinance is dated September 4, 2002; the township ordinances page also lists later township ordinances (2024-2 solar, 2024-3 renewable energy overlay district, 2024-4 battery energy storage, 2024-5 and 2024-6 PA 233 compliance) that were not reviewed and may change the district rules.
  • The zoning ordinance is administered by a township zoning administrator, and zoning permits are issued under Article III.

  “township of watertown zoning ordinance ordinance no. 200 adopted september 4, 2002”

• Zoning districtsPublished

  All land inside Watertown township's limits.

  • Zone boundaries are shown on a zoning map the ordinance says is part of it; the map itself was not opened, so individual parcel districts are not confirmed.
  • Districts named in Section 4.01: AR agricultural-residential, R single family residential, RM multiple family residential, MHP manufactured housing park, C commercial, I industrial.

  “the township is hereby divided into the following zoning districts: ar r rm mhp c i agricultural - residential single family residential multiple family residential manufactured housing park commercial industrial”

• Minimum dwelling sizeSpecified

  Single-family dwellings inside Watertown township.

  • The minimum floor area is set by the table in Section 11.02, which was not reliably extracted from the ordinance text; the numeric floor area by district is therefore not recorded here.
  • Minimum width of 14 feet applies to each single-family dwelling in all directions.

  minimum width in all directions: >= 14 feet

  “e ach dwe lling s hall be n o les s tha n fourteen (14) feet in width in all directions.”

• Accessory dwellingsProhibited

  Occupying garages, barns, accessory buildings, or basements as dwellings inside Watertown township.

  • This is a ban on occupying accessory buildings as dwellings; it does not by itself address an accessory dwelling unit built as an addition to a completed dwelling.
  • Applies to temporary or permanent occupancy.

  “garages, barns, accessory buildings, and basements shall not be occupied either temporarily or permanently as dwellings.”

• Permit feesVariable (with conditions)

  Zoning permits, applications and inspections in Watertown township.

  • The ordinance does not state fee amounts; fees are set by the township board. The township's schedule of fees page was linked from the township homepage but was not opened.

  “the amount of any fees charged for zoning permits, applications, or inspections shall be established by the township board.”

• Permit processPartial

  Zoning permits issued by the township zoning administrator in Watertown township.

  • Article III describes the zoning administrator and zoning permits; only the private-covenant rule was extracted. Application steps, forms and review timelines were not confirmed.

  “the zoning administrator shall not refuse to issue a zoning permit due to violations of private covenants, agreements, or deed restrictions if the proposed use is permitted by the zoning ordinance.”

Rules another office applies inside Watertown Township

Watertown Township does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

• Who permits septicCounty (with conditions)

  Proposed lots under one acre inside Watertown township created under the ordinance's cluster housing option. The county health department's septic standards are the rule referenced by the township ordinance.

  • The ordinance refers to the county health department's septic standards but does not state them, so the county septic permit process is not confirmed in this record.
  • General septic rules for ordinary lots in the township were not found in the ordinance text reviewed.

  lot size threshold for county septic standard: < 1 acre (cluster housing option (Section 5.02 or Article VI cluster provisions))

  “proposed lots under one (1) acre in size shall meet the septic standard s of the county he alth de partm ent.”
