Understanding Michigan Building Code: Permit Deadlines and Expiration Rules

When embarking on a construction project in Michigan, it is crucial for contractors, builders, and homeowners to be aware of the state’s building codes and regulations. One of the key aspects of these regulations is the timeline in which construction must commence after a permit is issued and how long a permit remains valid if work is paused. This article will delve into these aspects, providing clarity on permit deadlines and expiration rules under Michigan building codes.

Michigan Building Codes Overview

Michigan’s building codes are governed by the Michigan Building Code (MBC), which is based on the International Building Code (IBC) but with certain state-specific amendments. The MBC sets forth guidelines for construction projects, ranging from residential homes to commercial buildings, and outlines safety standards, structural requirements, and permitting processes.

Obtaining a building permit is a required first step in the construction process for most projects. The permit ensures that the construction complies with local safety, zoning, and structural codes. However, the process doesn’t end with approval—there are important timelines to observe regarding when work should commence and when it might expire if the project stalls.

Timeline for Beginning Work After a Permit is Issued

In Michigan, once a building permit is issued, the clock starts ticking on the timeline for beginning the construction or remodeling work. According to state regulations, the work must typically begin within 180 days (or 6 months) from the date the permit is issued.

If construction does not start within this timeframe, the permit may become invalid. This rule ensures that projects are carried out in a timely manner and reduces the chance of permits being left in limbo indefinitely.

In practice, local municipalities may enforce this rule strictly, so it’s essential to start work within the specified period to avoid complications or potential reapplication for a new permit. Additionally, some jurisdictions may offer a grace period, but this should not be relied upon, and it’s always wise to confirm with local building authorities.

Work Stoppage and Permit Expiration

One of the most commonly misunderstood aspects of construction permits is what happens if work on a project is paused after the permit is issued. According to the Michigan Building Code, if construction work stops and no progress is made, the clock continues to run. This means that if work halts for an extended period, the permit may expire.

In Michigan, if construction ceases for more than 180 days (6 months), the permit is generally considered void, and the project will need to be reevaluated. This means that if there is a significant delay or break in work, the builder or homeowner may have to reapply for a new permit before continuing construction.

There are some exceptions to this rule, especially if the work stoppage is due to extenuating circumstances, such as severe weather, natural disasters, or other unforeseen delays. However, such situations would require documentation and approval from the local building authority to avoid invalidating the permit.

Extension of Permits

In cases where a project is experiencing delays that extend beyond the 180-day period, builders or homeowners can apply for an extension. Local building departments may offer a permit extension, but it’s important to keep in mind that extensions are not guaranteed. Generally, an extension must be requested before the original permit expires, and additional fees may be involved.

The approval of a permit extension often depends on the specific nature of the delay, the local jurisdiction’s policies, and the project’s progress to date. For example, if substantial progress has been made and the project is close to completion, an extension may be granted. However, if no work has been done or if the delay is unjustified, the extension may be denied, and a new permit will need to be applied for.

Key Takeaways

• Start Work Within 180 Days: Michigan building codes require construction to begin within 180 days (6 months) after a permit is issued. Failing to do so may render the permit invalid.
• Permit Expiration After Work Stops: If work ceases for over 180 days, the permit may expire, and the builder must reapply for a new permit to continue the project.
• Extensions May Be Possible: In cases of significant delays, extensions may be requested. However, approval is not automatic and is subject to local authority rules.
• Check Local Regulations: Always verify with your local building department, as municipalities may have specific rules or offer grace periods beyond the state code.

By adhering to these rules, builders and homeowners in Michigan can ensure that their projects move forward smoothly and in compliance with state regulations. It’s always advisable to stay informed about permit expiration and time limitations to avoid costly delays and the need for reapplications.
