Do you need a building permit in Berrien County, Michigan?

Yes. Before constructing a building or structure in Berrien County, the owner or project representative must submit a written building-permit application to the appropriate enforcing agency; a permit is also required for a change in use or occupancy¹. Ordinary repairs are exempt only when they do not involve structural, egress, plumbing, electrical, mechanical, public-health or safety work¹. Township building departments enforce permits locally, with Berrien Township's Building/Zoning Department serving as one example². Construction follows the 2021 Michigan Building Code and Michigan Residential Code, effective April 9, 2025, with Michigan amendments¹⁰. After completion, the permit holder must request a Certificate of Occupancy in writing; all fees must be paid, permits finalized and work compliant before the code official may issue it⁵.

Who issues building permits in Berrien County?

Building permits are enforced through local township departments rather than a single countywide office². Berrien Township is one documented example: its combined Building Inspector/Zoning Administrator offers general building permits for pools, roofs, sheds and pole barns, a separate mobile-home building permit, and zoning applications for fences, signs and garden sheds under 200 square feet¹¹. In Berrien Township, mechanical and plumbing permit applications are administered through the State of Michigan¹¹. Reach that township office at 269-461-6925 only for land inside Berrien Township¹¹. For a parcel elsewhere in Berrien County, identify the applicable local unit and ask which agency enforces building, electrical, mechanical and plumbing permits before filing; the confirmed countywide rule is that the application goes to the appropriate enforcing agency¹.

Does Berrien County have zoning?

Yes, but it's set township by township, city by city, not by the county³. Michigan's Zoning Enabling Act lets counties, townships, cities and villages each establish their own zoning districts, but it doesn't define what those districts are; you have to check the ordinance for your specific local unit¹². The Berrien County Planning Commission's role is countywide master planning and coordinating studies of the county's economic, social and physical development, not deciding individual zoning or rezoning requests¹³. That means minimum lot size, setbacks, and whether RVs, tiny homes or manufactured homes are allowed on your land all depend on your specific township, city or village's own zoning ordinance. In Berrien Township, for example, a zoning application on its own (separate from a building permit) covers things like fences, signs and small garden sheds¹¹. Confirm your parcel's zoning district directly with the local unit it sits in.

How do septic permits work in Berrien County?

The Berrien County Health Department administers septic applications for homes where public sewer is unavailable⁴. A homeowner or contractor must file an application with the Health Department before installing a septic system¹⁴. The county's published 2024 Environmental Health fee schedule lists a septic-system application at $350 for each site; ask the office whether a later schedule now applies⁶. Buildings with plumbing fixtures must connect to public sewer where available or to an approved private sewage-disposal system¹⁵. Only 10.8% of Berrien County soils rate free of severe limits for a conventional drain field, so confirm site suitability before committing to a house location or budget⁸. Call the Environmental Health Office at 269-927-5623 to begin¹⁴.

Can you live in an RV or tiny home on your land in Berrien County?

Berrien County's own pages don't give a countywide answer to whether you can live in an RV on your land, because occupancy rules like this are set by each township, city or village's own zoning ordinance rather than by the county³. Ask the building/zoning office for the specific township where your parcel sits before you buy or move a unit in; Berrien Township, for instance, treats a mobile home as needing its own building permit separate from a general one¹¹. A permanent tiny home, like any other dwelling, has to meet the same 2021 Michigan Residential Code the local enforcing agency applies to any house, and it can't be occupied until that agency issues a Certificate of Occupancy¹⁰¹⁶. If it needs its own septic system rather than a sewer connection, that system still goes through Berrien County's Health Department and its permit process¹⁴. Because both the zoning classification and the permit path for an RV, tiny home or mobile home vary by township, get it confirmed in writing from your specific local unit before you rely on a rule you heard applied elsewhere in the county.

Building a home in Berrien County: the steps, in order

1. Identify the township, city or village containing the parcel, then confirm the zoning district and the appropriate building-code enforcing agency³¹.
2. Ask the local zoning office whether the proposed house, access, setbacks and any temporary RV use are allowed; Berrien Township's combined Building Inspector/Zoning Administrator is one example of this local setup¹¹.
3. If public sewer is unavailable, file the septic application with the Berrien County Health Department; the published 2024 fee is $350 per site⁴⁶.
4. Submit the written building-permit application to the appropriate enforcing agency before construction¹.
5. Build to the 2021 Michigan Building Code and Michigan Residential Code¹⁰.
6. Finalize every permit, pay all fees and request the Certificate of Occupancy in writing; do not occupy a new or altered building before the code official issues it⁵.

What to check before you buy land in Berrien County

Berrien County sits along Lake Michigan in Michigan's southwest corner, with the nearest city of 100,000 or more people about 23 miles from the county's center⁹. Population density runs about 268.2 people per square mile, and 41.9% of the county is wooded, with 95.9% of land at 15% slope or less, so most terrain won't be a build obstacle¹⁷¹⁸¹⁹. Federal land covers only 0.1% of the county, so almost everything you'll look at is privately held²⁰. Soils are the check that matters most before you commit: with only 10.8% of Berrien County's soils rating free of severe limits for a conventional septic drain field, get a site evaluation from the county Health Department before you settle on a specific parcel⁸. Farmland runs about $6,476 an acre by the USDA census, and a typical home is valued around $286,643²¹²². The effective property tax rate is about 1.1%, with a median annual bill near $2,357²³²⁴. If you're dividing or platting land rather than buying an existing parcel, Michigan's Land Division Act governs subdivision plats and final recordation at the Register of Deeds²⁵.

Watch-outs

• Building permits and zoning are handled locally in Berrien County, so identify the enforcing agency and zoning office for the parcel before relying on rules from another township²³.
• Only 10.8% of Berrien County's soils rate free of severe limits for a conventional septic drain field, so budget time and money for a site evaluation and possibly an engineered system on most parcels⁸.
• In Berrien Township, mechanical and plumbing permits are administered through the State of Michigan rather than the township office; ask your own township whether the same split applies before assuming who to call¹¹.
