Roof Repairs in a Michigan Historic District: Permits, Materials and Tax Credits

Three kinds of "historic" get confused. A local historic district or landmark is created by ordinance under Michigan's Local Historic Districts Act and comes with a commission that reviews exterior work. The State Register of Historic Sites and the National Register of Historic Places are honor rolls. The National Park Service says plainly that, under federal law, National Register listing places no restrictions on what a non-federal owner may do with their property, unless a project receives federal assistance such as funding or licensing.

So the question that matters for a roof repair is whether a local ordinance covers your address. Ask your city or township planning department, or check its historic district maps. In Grand Rapids, the Historic Preservation Commission's guidelines say the city has designated six multi-resource historic districts and 79 local landmarks since 1973, including Heritage Hill, Heartside, Cherry Hill and Fairmount Square; the Planning Department publishes district and landmark maps.

Section 5(3) tells commissions to follow the U.S. Secretary of the Interior's Standards for Rehabilitation and Guidelines for Rehabilitating Historic Buildings, and to consider the historic and architectural value of the building, how its features relate to the surrounding area, and the general compatibility of the design, arrangement, texture and materials proposed. A commission cannot deny an application for reasons outside that list, and it reviews only exterior features unless the local legislative body has authorized more.

The National Park Service's Preservation Brief 4, Roofing for Historic Buildings, explains the thinking behind those standards. It notes that asphalt shingles and roll roofing were already in use in the 1890s, that failure of the flashing system is usually a major cause of roof deterioration, and that on roofs with a high degree of visibility, a substitute material may seriously alter a building's character. It also warns that patching with caulking or bituminous compounds is potentially harmful to historic roofs, because those materials are hard to remove and at best very temporary.

The act lets a commission delegate certificates for minor classes of work to its staff or the building inspector, using written standards. Grand Rapids lists in-kind repairs and reroofing among the examples of minor work its staff can approve, says staff reviews typically take one to two days, and says full commission reviews typically take two to four weeks because the commission meets monthly. A certificate there is valid for twelve months. Grand Rapids' fiscal 2027 fee schedule lists $27 for a staff-review certificate and $92 for a basic commission review.

Michigan restored a state historic preservation tax credit with 2020 PA 343, now MCL 206.676. For an owner-occupied home in a local historic district, or individually listed or contributing to a State or National Register listing, the credit is 25 percent of qualified expenditures under a rehabilitation plan that meets the Secretary of the Interior's Standards. The statute sets the residential minimum at $1,000 of qualified expenditures, adjusted annually for inflation, and allows certificates of completed rehabilitation issued before 1 January 2031.

Credits are limited. The statute caps all credits reserved at $5 million per calendar year, with at least $1 million for residential projects when demand is there. The State Historic Preservation Office's program page says owner-occupied applicants could apply for 2026 credits starting 2 January 2026 until credits run out, and a 24 September 2026 update says 2026 applications must be received by 30 November 2026, delivered by a tracked courier or mailing service. Applications received after the year's credits are committed may be given priority for 2027.

SHPO strongly recommends applying and getting approval before work begins, because the three-part application reviews the plan before construction and the finished work after. If a roof replacement on a historic home is coming anyway, check SHPO's page for the current year's status before you sign a contract. This is not tax advice; ask a tax professional how a credit would apply to your return.
