Have a question on historic preservation, easements, landmarks or how to get involved in our organization? Landmarks Illinois preservation experts provide detailed answers to our most commonly heard questions.



What is a “historic landmark?”

Traditionally, “historic landmark” has often referred to places with an official landmark designation, whether via a local municipal designation or the National Register of Historic Places. This means a governing body has decided a place is significant and worthy of protection. At Landmarks Illinois, we take a more expansive view. Many places that hold value to a community have no formal designation but are referred to as landmarks. We agree with this inclusive view of historic landmarks and are committed to the research, recognition, designation and preservation of these important places.

What does “historic preservation” mean?

At Landmarks Illinois, we believe historic preservation is best described though our mission of people saving places for people. Historic preservation is the act of conservation and protection of these buildings, sites, objects and landscapes that are significant to our personal or shared stories. In action, this looks like:

  • A 22-year effort to reuse a landmark on Chicago’s Near West Side, resulting in a $140 million investment and creation of an estimated 900 jobs
  • Telling the full story of people’s experience and the historic places along Route 66
  • forming a broad coalition of community leaders, advocates and business owners to give an Art Deco landmark a new life instead of sending it to a landfill
  • The acquisition, disassembly and storage of an iconic kitchen used for decades by Ebony Magazine food editors with the end goal of finding a new home for its public display


How do I find a list of landmarks in Illinois?

There are multiple resources available to the public to find designated landmarks in Illinois.


How do I find out if my house/property is a landmark?

The best way to learn if your property has any existing landmark designation at the local or federal level, inquire with your local planning department. For example, residents of the City of Chicago should contact the Chicago Department of Planning and Development. You can also use the city’s zoning map, which indicates all historic designations under the zoning tab. Other resources:


If my house/property is a landmark, what does this mean?

There are various ways a property can be deemed a landmark: listing in the National Register of Historic Places, designated a National Historic Landmark or designated a local landmark. Each of these designations has a different level of protection and distinction.

National Historic Landmark and National Register of Historic Places listing are purely honorific offering no protection to the property unless federal funds are used.

Designation as a local landmark or contributing to a local landmark district offers protection through a local historic preservation ordinance. These ordinances vary and are specific to each community.

How do I landmark my property? And how does the landmarking process work?

Landmark designation for a historic property or district is administered at a local municipal level if the local municipality has a historic preservation ordinance. To find out if your local government has a historic preservation ordinance, contact the local department of planning office (city, village or county) or determine if it is a Certified Local Government (CLG), which is a local government with a historic preservation ordinance that has been certified by the State Historic Preservation Office (SHPO).

Properties can also be listed in the National Register of Historic Places (a federal program of the National Park Service) and the nomination process is administered by the state’s historic preservation office. To determine if your historic property is eligible for listing in the National Register of Historic Places, follow the preliminary evaluation process as instructed on the Illinois SHPO website.

If my property is included in a historic district, will I have to reverse previous alterations or are they grandfathered?

If a property is included in a historic district, designated at the local level or to the National Register of Historic Places, previous changes to a property do not need to be reversed. Only future alterations to the property (generally exterior) may require review by the local historic preservation commission. If a property in Illinois is located in a National Register district, future alterations (exterior and interior) will be reviewed by the Illinois SHPO if an owner chooses to utilize a financial rehabilitation incentive or if an owner is using federal or state funds/permitting to alter the property.

What are the benefits of landmark designation?

Landmark designation at the local level (individually or in a district) may provide a property owner the opportunity to utilize local financial incentives for rehabilitation. The local department of planning office or local historic preservation commission (HPC) can provide this information.

Listing in the National Register of Historic Places (individually or in a district) provides the opportunity to utilize financial incentives for qualified rehabilitations. These programs are administered by the IL SHPO.

What is the difference between a local landmark and a national landmark?

LOCAL LANDMARK: A local landmark is a designated property, building, site or structure that has been deemed important by a local governing body. It must meet certain criteria identified in a local historic preservation ordinance to be deemed eligible for designation as a local landmark or to be included in a local historic district.

Local landmarking can be an effective tool to preserve significant places and areas within a community and preserve the unique character and history of a city, town, neighborhood or individual place. See an example of the local landmarking process at the City of Chicago’s website. Local landmark designation generally provides protection for historic buildings from future demolition or alternations that could compromise the historic character, design or integrity of a building. Restrictions and regulatory oversight of locally landmarked properties varies by community based on its historic preservation ordinance.

NATIONAL LANDMARK: A national landmark can be one of several designations bestowed by the National Park Service. See the answer to the question below.

What is the difference between a “national landmark” and a property listed in the National Register of Historic Places?

NATIONAL HISTORIC LANDMARK: A national historic landmark is a historic place that holds national significance because it illustrates the heritage of the United States, according to the National Park Service. National Historic Landmarks, or NHLs, can be buildings, sites, structures, objects and districts. There are approximately 2,600 NHLs in the United States, 87 of which are in Illinois.

NATIONAL REGISTER OF HISTORIC PLACES: The National Register of Historic Places is the official list of our country’s historic buildings, districts, sites, structures and objects worthy of preservation. Properties on the National Register are primarily of state and local significance. The National Register was established as part of the National Historic Preservation Act of 1966 and is overseen by the National Park Service. A property must be listed on the National Register of Historic Places to be eligible for Federal Historic Preservation Tax Incentives program, a vital incentive for the rehabilitation and reuse of historic buildings. Learn more at the NPS website.

Will landmarking impact my property value and/or property taxes?

Some studies have shown that local landmark designation, particularly designation of a historic district, can stabilize or increase property values due to the desirability of living in a neighborhood where owners are highly invested in their historic properties, in turn contributing to the neighborhood’s desirability. However, landmark designation ultimately has less impact on one’s property value or property taxes than other local factors, such as zoning, safety, access to good schools and other amenities. Local historic preservation ordinances differ in their level of protection and oversight. Local rehabilitation incentives made available in a community differ as well, which may or may not impact property values or property taxes of designated properties.

Generally, National Register designation will have no impact on property values or property taxes due to the fact that its designation is only honorific and National Register-listed properties can be altered or demolished. (Regulatory review of a threatened National Register-listed property only occurs by the state’s historic preservation office if federal or state funds or permits are involved in the action threatening the property).See the following studies addressing property values:

An owner of a historic property may choose to donate a preservation easement to a qualified historic preservation organization, such as Landmarks Illinois, which provides protection of that property in perpetuity. This level of protection can lower one’s property value and in turn, the donor may seek a federal tax deduction for the easement donation. See below for definition of a preservation easement.

What is a preservation easement?

A preservation easement is a legal agreement between a property owner and a qualified easement-holding organization that protects a significant historic or cultural resource in perpetuity. Preservation easements are recognized as the strongest and only perpetual protection available for historic properties. Landmarks Illinois protects nearly 550 historic properties through preservation easements. For more information, click here.

How many easements does Landmarks Illinois have?  

Landmarks Illinois protects nearly 550 historic properties across the state with preservation easements.

How do I donate a preservation easement to Landmarks Illinois?

If you are interested in donating a preservation easement, please review our donations procedures document. You can also reach out to Suzanne Germann, Director of Grants and Easements, at (312) 922-1742 or email for more information.

I just bought a property that has a preservation easement. Now what?

Owners of properties protected by a preservation easement are required to obtain the approval of Landmarks Illinois before making alterations to the protected elements of the property. Please contact Landmarks Illinois prior to commencement of any work to ensure that proposed maintenance and alterations are in accordance with the easement agreement. If necessary, you will need to complete a Request for Alterations Form. You can also contact Suzanne Germann, Director of Grants and Easements, at (312) 922-1742 or email for more information.

How do I sell my property when it has an easement?

The seller of the property is required to notify Landmarks Illinois in writing of any proposed sale of the property and provide the opportunity for Landmarks Illinois to explain the terms of the easement to potential new owners prior to sale closing. We encourage the seller to alert their realtor and any potential buyer about the easement.



How do I find a professional to do work on my historic home or property?

Landmarks Illinois’ Restoration Resource Directory provides property owners and design professionals with access to professional services, products, craftspeople and other experts related to the maintenance, restoration and rehabilitation of older structures.

Please note that this directory is not intended to be comprehensive or an endorsement – it is for your convenience. Omission from the list does not imply that a provider is unqualified. Inclusion in the list does not verify the provider’s qualifications, experience or ability. Landmarks Illinois recommends that you request and check references before hiring any service provider.

Is rehabilitating my historic property more expensive than new construction?

Rehabilitation is often comparable in cost or less expensive than new construction, especially if the new construction includes demolition costs. In addition to individual costs for a project, building rehabilitation and reuse has been documented to catalyze local economic development and improve job creation, property values, heritage tourism and neighborhood revitalization. For more information, please see the report, “Measuring the Economic Impacts of Preservation: Recent Findings.”

Can I apply for funding to maintain or restore my historic building?

Landmarks Illinois has three grant programs available to nonprofit organizations or governmental bodies for their preservation projects: The Preservation Heritage Fund Grant Program and the Barbara C. and Thomas E. Donnelley II Preservation Fund for Illinois and the Timuel D. Black, Jr. Fund for the Chicago’s South Side. Learn about Landmarks Illinois’ grant programs here. You can also click here for a list of grants and incentives available through other organizations.

What tax credit programs are available to historic property owners?

There are several state and federal programs available to historic property owners. For instance, the Illinois Historic Preservation Tax Credit Program provides a state income-tax credit equal to 25% of a project’s Qualified Rehabilitation Expenditures (QREs), not to exceed $3 million, to owners of certified historic structures who undertake certified rehabilitation projects. More information on the Illinois Historic Tax Credit Program is available on the Illinois State Historic Preservation Office’s website.

Information on these programs and many more other financial incentives is also available on our Financial Resources webpage.

In addition, historic property owners should contact their local government for any local programs or incentives for historic property owners.

For all programs, we encourage owners to contact the program administrators for more information prior to beginning work on a project.

Should I replace my old windows on my historic home or building?

The windows on many historic buildings are an important aspect of the architectural character of those buildings. Their design, craftsmanship or other qualities may make them worthy of preservation. The California State Parks Office of Historic Preservation provides the most thorough evaluation of the historic window topic including studies and research.

Beyond the historic integrity of a building, energy efficiency is a concern when it comes to windows. To understand more, read The National Trust for Historic Preservation’s Preservation Green Lab report “Evaluating the Energy Performance of Window Retrofit and Replacement,” which provides data on the topic.

For those considering restoring their windows, the National Park Service Preservation Brief: The Repair of Historic Wooden Windows is a good resource.

If you are looking for a professional to restore your windows or custom build an appropriate replacement or storm window, check our Illinois Restoration Resources Directory.
