Frequently Asked Questions
What is the I-81 viaduct project and how does it affect my Syracuse property?
The I-81 viaduct — a highway elevated above street level through central Syracuse since the 1960s — is being demolished and replaced with a 'community grid' of urban streets. This major NY State DOT project (ongoing 2024-2030) is one of the most significant urban highway removals in US history. Properties near the old viaduct route (East Washington Street corridor, Near Eastside) will see major traffic pattern changes and development opportunities. The project aims to reconnect neighborhoods severed by the highway and create a walkable urban street network.
Can I build an ADU in Syracuse?
Yes — Syracuse allows accessory dwelling units on residential lots under its local Zoning Code. Detached ADUs up to 800 sqft are permitted in rear or side yards. No owner-occupancy requirement. Building permits take 4-8 weeks. Syracuse University's student population and SUNY Upstate Medical University create steady rental demand in nearby neighborhoods like Westcott and University Hill.
Is Syracuse really the snowiest city in the US?
Syracuse consistently ranks as one of the snowiest major cities in the US — averaging around 124 inches per year compared to the US average of about 28 inches. Lake Ontario's lake-effect snow machine aims at Syracuse due to the prevailing wind direction. For homeowners, this means heavy-duty roof construction (snow load rated), robust heating systems, adequate snow storage space in driveways, and vigilant maintenance. The snow load is factored into all Syracuse building codes. On the positive side, winters create tourism for the Tully Farms corn maze in fall and winter recreation in the Finger Lakes region.
What neighborhoods near Syracuse University are best for renting?
Westcott is the most popular neighborhood adjacent to SU — walkable, artsy, with local restaurants and coffee shops. University Hill sits immediately adjacent to the SU campus. The Hawley-Green area has more affordable older housing. Strathmore and Eastwood are established residential neighborhoods further from campus but still popular with faculty and graduate students. Syracuse's rental market is heavily influenced by the university academic calendar — supply and vacancy rates shift significantly in August (move-in) and May (move-out).
What is Onondaga Lake and why was it contaminated?
Onondaga Lake is a 4.6-square-mile lake on the northwestern edge of Syracuse. It was severely contaminated by over a century of industrial dumping — primarily from the Solvay Process Company which produced soda ash from the area's natural salt deposits from the 1880s-1980s. By the mid-20th century, Onondaga Lake was considered one of the most polluted lakes in the US. A major EPA Superfund remediation project, led by Honeywell (which acquired Allied Signal which acquired Solvay's successor), has significantly cleaned the lake. The shoreline is being developed as Onondaga Lake Park with trails and public recreation.
Are there programs for rehabbing older Syracuse housing?
Yes — Jubilee Homes, Home HeadQuarters (HHQ), and the City of Syracuse CDBG programs provide rehabilitation assistance for low-to-moderate income homeowners. NY State Homes and Community Renewal (HCR) offers programs for affordable housing creation. Empire State Development has supported several major Syracuse developments. Contact Home HeadQuarters at homeheadquarters.org for information on affordable home improvement loans and purchase programs.
