Resources for Mills Owners & Developers

interior Bport Mattressinterior Sherwood LoftsA variety of programs at the municipal, state, and federal levels offer assistance to help move forward the redevelopment of historic mills and factories. The resources outlined below are intended to provide useful information, however you should contact the administering entities directly for details on currently available programs.

To see how some of these tools have been used in mill reuse projects, preview our sample Got Mill?

You can also reach out to the Connecticut Trust for Historic Preservation, whose staff have expertise on a broad range of preservation issues, tax credits, and economic incentives for rehabilitation.

Historic Designations

Designating a property as architecturally and historically significant can encourage preservation, promote awareness, and protect a sense of place and character of our communities. Grants and historic tax credits are available for planning and development of mills and factories on the State and National Registers of Historic Places, and are administered by the State Historic Preservation Office (SHPO). More information can be found under ‘Financial Incentives’ below and at the SHPO website.

National Historic Landmark

National Historic Landmark is the highest level of designation available. Properties given this foremost form of recognition are deemed significant to all Americans because of their exceptional values or qualities, which help illustrate or interpret the heritage of the United States. The National Historic Landmark program identifies, designates, recognizes and protects buildings, structures, sites and objects of national significance.

As of 2017, Colt’s Patent Fire Arms Mfg. Co. in Hartford and the Cheney Brothers Mfg. Co. Silk Mill in Manchester are National Historic Landmarks.

National Register of Historic Places

The National Register of Historic Places is the nation's official list of historic buildings and sites worthy of preservation. Listing on the Register indicates that a property is significant because of its architecture or its association with important persons, events or cultural events. Listing does not restrict what a property owner may do with the property unless the owner is using federal or state assistance.

As of 2017, approximately 240 historic industrial sites are listed on the National Register either individually or as contributing resources in historic districts.

State Register of Historic Places

The State Register of Historic Places is the official listing of those sites important to the historical development of Connecticut. Listing on the State Register does not restrict the rights of the private property owner.

As of 2017, approximately 45 historic industrial sites are listed on the State Register either individually or as contributing resources in historic districts. The Making Places survey has identified 427 as candidates for listing, and nearly 300 more for future consideration.

State Historic Resource Inventory

The State Historic Resource Inventory identifies and evaluates historic, architectural, archaeological, cultural and industrial resources. Surveys which serve as the basis for most other designations are also useful tools for municipal officials, local planners, preservationists, property owners and researchers in helping them make sound preservation and development decisions. There are no restrictions associated with the Historic Resources Inventory.

Making Places: Historic Mills of Connecticut is a State Historic Resource Inventory completed in 2017.

Local Historic Districts/Properties

Local Historic Districts/Properties offer the most protection for significant architectural buildings and neighborhoods in the State of Connecticut. State law allows municipalities to establish historic districts and historic properties for which exterior architectural changes are reviewed by a local preservation commission. This allows towns that have Local Historic Districts/Properties to ensure that alterations, additions, or demolitions are in keeping and consistent with the special character of the designated area.

As of 2017, fewer than 10 historic industrial resources have been identified as contributing resources in Local Historic Districts.

Tax Credits

State and federal historic tax credits are administered by the State Historic Preservation Office (SHPO).

Federal Historic Preservation Tax Credit Program (administered through CT SHPO):

[10% on in use non-historic (pre-1937) non-residential depreciable buildings with substantial rehabilitation - phased out as of 2018];

30% on such projects with an affordable housing component (20% if they are rental units or 10% if they are for-sale units).

Rehabilitation must meet SOI Standards.

As a non-profit, the Connecticut Trust for Historic Preservation can partner with developers on state historic tax credit projects to reduce federal income taxes and make more equity available for the project itself.

Municipal Incentives

Municipal Tax Increment Financing (TIF) presented by CT Main Street Center:

State authorized financing tool used by local municipalities for economic development; the difference between taxes generated before and after investment in a property finance a portion of the costs of its redevelopment. This tool is generally adopted by municipalities in response to specific situations. Connecticut Main Street Center has been at the advocacy and implementation forefront of this tool.

Payment in Lieu of Taxes (PILOT):

Some towns may offer PILOT programs for redevelopment projects on land owned by the town.

Property Tax Abatement:

Overlay zoning/districts:

Local authorities may institute overlay zoning districts and regulations to encourage or place limits on certain types of development in particular neighborhoods. They are in addition to existing zoning regulations. In Southington for example, Redevelopment Overlay Districts were outlined in the Plan of Conservation and Development to encourage reuse and compatible redevelopment of historic industrial areas. The Town of Putnam’s Industrial Heritage Overlay District seeks to preserve and reuse its historic mills.
