Masonry Contractors in DeWitt: The Paperwork Is the Vetting
The insurance paperwork you should be asking a mason for is the same paperwork DeWitt will not process an application without, so asking costs you nothing. The town names fireplaces on the face of its permit page and wants workers compensation and disability proof, or a signed exemption, before it takes the form.

What the Town of DeWitt makes a mason produce
DeWitt's planning and zoning department names fireplaces on the face of its permit page, alongside additions, alterations, conversions and garages, so chimney and fireplace work here starts from the assumption that a permit is involved, and a certificate of occupancy affidavit plus a final inspection close it out. The more useful detail is what the town will not accept an application without: proof of workers compensation and proof of disability coverage on the state forms, or a Certificate of Attestation of Exemption. Set that beside the fact that New York does not license home improvement contractors at all, and neither Onondaga County nor the City of Syracuse is among the places that do it locally, so there is no masonry license for anyone to hold. What you can actually verify is exactly what DeWitt is going to demand anyway, which makes asking for it uncontroversial rather than awkward. The housing here gives no single answer. Of 10,996 units the median build year is 1963, with 18.7 percent built before 1940, 25.6 percent between 1940 and 1959 and 75.8 percent before 1980, while the DeWitt Census place inside the town is younger at 11.5 percent prewar with 26.8 percent from the 1950s alone. That is the most evenly mixed town in the metro, so both questions earn their keep on the same street: what is the mortar being matched to, and what is happening at the tops of the openings. One scoping note. Jamesville, the hamlet in this town, is not a Census-designated place and has no published median build year of its own, so DeWitt's figures are the closest published numbers covering it and they should be described as the town's rather than the hamlet's.

Onondaga County and the City of Syracuse are not among the jurisdictions named.

Jamesville is not a Census-designated place and does not appear in the American Community Survey place-level tables for Onondaga County. It is a hamlet in the Town of DeWitt, so the closest published housing-age figures covering it are DeWitt's: a median year of construction of 1963, 18.7 percent of units built in 1939 or earlier and 44.2 percent in 1959 or earlier. The National Park Service does record three individual National Register listings at Jamesville, the Dr. John Ives House, Saint Mark's Church and the Southwood Two-Teacher School.
