Mentor Avenue District
Also known as: See Also:City Hall; Sessions House
Why it's listed
Mentor Avenue in Painesville, Ohio, is lined with fifty-four buildings that trace nearly a century of changing architectural taste. The district runs from Liberty Street, where the Greek Revival City Hall and the Congregational Church stand, west to the Lake Erie College campus. Styles include Greek Revival, Italianate, Second Empire, Queen Anne, Romanesque Revival, and 20th century Cotswold and Georgian designs. Among the earliest buildings is the Denton-Powers house of 1820, attributed to architect Jonathan Goldsmith, who also is credited with the Levi Shepard residence and City Hall, built in 1840 as the Lake County Courthouse. The street also housed notable people, including Thomas Harvey, author of Harvey's Grammar and Harvey's Readers and later state school superintendent, and plow manufacturer Grandison Wilder. Few intrusions break the streetscape, giving the district an unusual coherence for its location near a city center, though commercial development presses on its eastern edge.
Significance in brief: The nomination argues the district is significant architecturally for the variety and quality of its buildings, which range from Greek Revival to Queen Anne and 20th century eclectic styles. It is also significant historically for residents of local and national reputation, including educator Thomas Harvey. The district has unusual continuity and coherence for its closeness to the city center.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
