Jefferson County Courthouse Complex
.jpg){kind=link}
Why it's listed
Three county buildings at the corner of Arsenal and Sherman Streets in Watertown form the Jefferson County Courthouse Complex. The centerpiece is the red brick courthouse of 1862, trimmed with limestone, with a tall second-floor courtroom and a three-story corner tower. Syracuse architect Horatio Nelson White designed it as a smaller version of his Onondaga County Courthouse, and John Hose built it after years of delay and drainage problems on a boggy site. Two later buildings sit beside it: the red brick Clerk's Office of 1884, designed by J. W. Griffin, and the greystone Surrogate's Office of 1905, designed by David Kieff. Both architects had ties to Hose, and the newer buildings repeat the courthouse's arched and lintelled window pattern and belt courses. The nomination presents the group as one of the finest clusters of county buildings in New York State. All three remain in county use, though the two smaller buildings faced threat from planned expansion.
Significance in brief: The complex is argued to be one of the finest clusters of county buildings in New York State. The courthouse was designed by Syracuse architect Horatio Nelson White and built by John Hose. The two later buildings were designed by Watertown architects J. W. Griffin and David Kieff, both linked to Hose, and they echo the courthouse's design.

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).
