One model for your community might be the City of Hartford, which adopted Connecticut’s first municipal preservation ordinance in 2006. Since then, Hartford’s volunteer historic commission has reviewed over 5,000 applications for new construction or alterations in local, State, and National Register districts. To minimize delays, the commission delegates routine matters to City staff. Thus simple projects, such as replacing a roof in like materials, can bypass the commission hearing.
The Hartford commission also works with property owners to find solutions and even to approve alternate materials for siding or replacement windows, if the alternate materials do not seriously impair historic character.
