Do you need a building permit in Howell, MI?

A home construction project in Howell needs a building-permit application before construction, subject to the code’s specific exemptions.1 Howell’s Building Official enforces the city’s adopted Michigan construction codes, and plans must pass the Zoning Administrator’s review before the building permit is issued.42

Submit the building application and application fee to Howell Community Development; the city’s instructions also require separate applications for building, electrical, mechanical and plumbing work.7 We could not confirm Howell’s owner-builder application requirements; ask Community Development what an owner acting as contractor must submit for the proposed home.7

Who handles Howell building permits, fees and inspections?

Howell’s Community Development Department receives building applications, reviews them for zoning compliance and sends them to the Building Official for construction-code review.7 Contact the department at (517) 546-3861 or [email protected], or use the city’s building-process instructions and application.7

Howell’s instructions specify a $50 non-refundable application fee; additional permit, review and escrow fees are communicated after approval, and payment precedes permit issuance.7 The contractor contacts Community Development to schedule required inspections, and the permit is finalized after all required final inspections pass, including building and applicable trade inspections.7

Does Howell have zoning, and can you live in an RV or tiny home?

Howell has its own zoning ordinance, and a certificate of zoning compliance is required before a building permit can be issued.32 If an application conflicts with zoning, Howell Community Development contacts the applicant to revise the application or apply for a variance.7

We could not confirm Howell’s rules for residential RV occupancy, temporary camping, tiny-home occupancy, accessory dwellings or minimum dwelling size; ask the city’s Zoning Administrator about the exact proposed use before buying a lot.3 Ask Howell Community Development to identify the parcel’s district and applicable lot-size, setback and dwelling requirements before commissioning plans.73

How do septic permits and sewer connections work in Howell?

Howell requires sewer connection at the owner’s expense within 90 days after official notice when a city public sanitary sewer lies within 200 feet of the nearest property line; written authorization and a city sewer connection permit are required.6 An off-grid plan must also comply with Howell’s restrictions on privy vaults, septic tanks, cesspools and other sewage-disposal facilities.9

Where an onsite system is applicable, Livingston County Environmental Health requires an approved soil evaluation before the septic-permit application, and the permit must be obtained before installation.58 The septic contractor must arrange the inspections listed on the permit, and changes need Environmental Health approval before excavation or construction.10 The completed septic permit must be on file with Howell’s building department before issuance of a Certificate of Occupancy for septic-served construction.11

Building a home in Howell: what are the steps, in order?

Start with Howell’s zoning review and the parcel’s sewer situation: zoning compliance precedes the building permit, and the city’s sewer-connection rule can determine the sanitation route.26

  1. Submit the building application and application fee to Howell Community Development for zoning review followed by Building Official review.7
  2. For an applicable septic system, obtain an approved soil evaluation and Livingston County Environmental Health’s septic permit before installation.58
  3. Pay the calculated permit fees and submit separate applications for applicable trade work.7
  4. Schedule required building inspections through Community Development and septic inspections through Environmental Health; arrange the final approvals before seeking occupancy clearance.71011

What should you check before buying land in Howell?

Ask Howell Community Development to review the intended use and building layout before buying, because the city requires zoning approval ahead of building-permit issuance.2 Confirm sewer availability with the city before assuming an onsite system is an option; Howell’s connection requirement depends on sewer distance and official notice.6

For a septic-served parcel, arrange the soil evaluation before the permit application.5 Only 1.1% of Livingston County soils are rated “not limited” for conventional septic drain fields; that countywide screening figure does not decide an individual Howell lot’s suitability or mean septic is impossible.12 Ask Howell about subdivision approval when dividing land, and ask Community Development who must approve the proposed driveway and any floodplain work; we could not confirm those project-specific approvals.137 For land outside city limits, use the Livingston County guide to understand the different building and zoning authorities.14

Watch-outs

  • Howell’s sewer-connection requirement can apply even when a buyer planned to use septic: the trigger includes sewer distance and official notice.6
  • We could not confirm permission to live in an RV or tiny home in Howell; ask the city’s Zoning Administrator about occupancy before relying on that plan.3
  • A septic-served Howell project needs the completed septic permit on file before the building department issues a Certificate of Occupancy.11
