Do you need a building permit in Porter Township, Michigan?

Porter Township issues building permits for covered construction, and work cannot start until the township issues the permit; changes in use or occupancy also require a building permit.1 Michigan’s construction codes govern building work in Porter Township, with dwelling provisions in the Michigan Residential Code.14

Porter Township calculates building-permit fees after reviewing the application and may assess third-party review fees; payment is due when the permit is ready for pickup.15 Michigan’s owner-builder licensing exemption applies to a residence built for the owner’s own use and occupancy on the owner’s property, but does not remove building-permit, inspection or zoning requirements.13

Who handles building permits and zoning in Porter Township?

Contact the Porter Township Building Official for building permits and coordination of building, electrical, mechanical and plumbing inspections.16 The Porter Township Zoning Administrator handles zoning review, building setbacks, proposed uses and zoning variances.2 Ask that office to identify the parcel’s applicable setbacks before finalizing a house location.2

Porter Township requires a completed application and applicable supporting documents together rather than piecemeal submissions.17 The township’s new-construction checklist includes zoning and building applications, plans, energy compliance, access and sanitation approvals, and an earth-change permit when applicable.17 Well and septic approvals come from the health department rather than the township building counter.18

Does Porter Township zoning set minimum lot and home sizes?

Porter Township’s residential lot requirements differ by district: R-1 requires at least 1 acre and 220 contiguous feet of width at a public road, subject to the community open-space development exception.6 R-2 requires at least 32,670 square feet, with 120 contiguous feet at the building line and 90 feet on a limited-access road, subject to that district’s community open-space exception.7 R-L requires at least 10,890 square feet with the same 120-foot building-line and 90-foot limited-access-road dimensions, subject to its community open-space exception.8

Porter Township limits impervious coverage to 25% in R-1 and 35% in R-2 and R-L, so lot area alone does not establish how much can be built or paved.192021 Ask the township Zoning Administrator about setbacks and the proposed building footprint.2

Can you live in an RV or tiny home in Porter Township?

Porter Township allows an RV to provide temporary housing for guests or visitors for no more than 30 days in any 12 consecutive months, provided occupants have unrestricted use of the principal building’s sewage-disposal and water-supply facilities.5 That guest-housing provision does not establish permission to live in an RV on vacant land; ask the township Zoning Administrator about the proposed occupancy and any applicable temporary-use approval.52

For single-family homes in Porter Township’s R-1, R-2 and R-L districts, the minimum first-floor area is 960 square feet and the dwelling must be at least 24 feet wide over its entire length; a smaller tiny-home design would not meet those dimensions.101112 We could not confirm a separate accessory-dwelling allowance; ask the Zoning Administrator before planning a second dwelling.2

How do septic and well permits work inside Porter Township?

The Van Buren/Cass District Health Department’s septic jurisdiction includes Porter Township, and the township requires proof of well and septic permits for new construction using those systems.322 Porter Township also requires septic approval before issuing a building permit for additions or alterations that increase bedrooms; in a sewer district, the plumbing inspector supplies the sewer permit instead.9

The district’s published new-construction septic fee is $300, and its application process calls for property information, a scaled drawing where required and payment.2324 Health-department permits are valid for 1 year.24 Van Buren County’s soil data rates 0% of soils “not limited” for conventional septic drain fields; this county-level screening supports a parcel evaluation and possibly an engineered system, not a conclusion that septic is impossible.25

What are the steps to build a home in Porter Township?

  1. Ask the Porter Township Zoning Administrator about the proposed use, setbacks and zoning review.2
  2. Arrange access approval: a county-road driveway permit is required before applying for a new address; state-road access uses MDOT, while private-road access requires a site plan rather than a driveway permit.26
  3. Obtain applicable well and septic approvals from the health department, or sewer approval from the plumbing inspector in a sewer district.49
  4. Submit the township building application, plans and applicable checklist documents together, then wait for issuance before beginning work.171
  5. Arrange inspections before concealing work; if approved drawings change, supply as-built plans before the certificate of occupancy is issued.2728

Porter Township’s building permit is valid for 180 days, with extensions at the building official’s discretion, so discuss timing before delaying construction.17

What should you check before buying land in Porter Township?

For a Porter Township parcel with private sanitation, confirm the disposal-field location early: the district health code prohibits a disposal field in the 100-year floodplain.29 Michigan also regulates alteration or occupation of certain river, stream and drain floodplains, and prohibits new residential construction in the floodway.30 Ask the township Building Official which local floodplain approvals apply to the proposed work.16

Porter Township regulates land divisions and requires supporting survey or drawing information, access documentation, tax clearance and a $150 application fee.31 For land outside Porter Township, use the Van Buren County guide and identify the relevant local municipality, because zoning is administered by the city, village or township.32

Watch-outs

  • Adding bedrooms can trigger septic approval before a Porter Township building permit, even without building a new home.9
  • Porter Township’s guest-RV allowance depends on access to the principal home’s sewage and water facilities; do not treat it as a vacant-land residential allowance.5
  • We could not confirm Porter Township’s operative short-term-rental rules or a complete agricultural building-permit exemption; ask the Zoning Administrator and Building Official before committing to either use.216
