Onondaga County
Service Coverage in Jamesville, NY
Jamesville has no government and no permit office of its own, so every roofing permit question here is answered by the Town of DeWitt Planning and Zoning Department at 5400 Butternut Drive. It also sits on the wooded hills in the south of the town, where tree cover over the roof and the state's elevation adjustment to ground snow load both come into play.
Planning work in Jamesville
Jamesville is an unincorporated hamlet. It has no village government, it does not appear on the Onondaga County Clerk's roster of towns and villages, and building permits and code enforcement run through the Town of DeWitt at 5400 Butternut Drive. That settles the filing question, and DeWitt's rule is a threshold rather than a trade list, so the town's answer on whether a given re-roof counts as more than a minor repair should be obtained in writing. The county hazard plan describes the southern part of DeWitt, where Jamesville sits, as hilly, generally mixed forest and fields with limited residential development, quarry operations and Butternut Creek running through it, with Route 173 crossing at the hamlet. In practice that means overhanging limbs, moss on north slopes and debris collecting in valleys are ordinary maintenance issues here in a way they are not on an open suburban street. Elevation is worth checking rather than assuming: the state adds 2 pounds per square foot to the mapped ground snow load for every 100 feet above 1,000 feet, so a site on high ground can be designing to a heavier load than one on the lake plain, which matters if a sagging deck is being rebuilt rather than re-covered. One honest limit: there is no place-level census housing age figure for Jamesville. The nearest published measure is the Town of DeWitt, where 18.7 percent of units were built in 1939 or earlier, and that is what it is, a town figure standing in for a hamlet.

Under 19 NYCRR section 1220.3(a), which amends footnote o to Table R301.2(1), sites at elevations above 1,000 feet must have their ground snow load increased from the mapped value by 2 pounds per square foot for every 100 feet above 1,000 feet. The state gives the worked example that a site at 1,200 feet carries a ground snow load 4 psf above the mapped value.
