Frequently Asked Questions
How has Kodak's decline affected Rochester housing?
Eastman Kodak's peak employment of 60,000+ in Rochester declined to under 2,000 by 2020 — one of the largest employer collapses in US history. This created significant neighborhood disinvestment, affordable housing, and vacant properties in Rochester. The upside: Rochester homes are extremely affordable by national standards, and the city's academic and medical institutions (University of Rochester Medical Center, RIT) provide economic stability. Innovative reuse of former Kodak buildings (Kodak Park → Eastman Business Park) is a major city initiative.
What is a Rochester garbage plate?
The garbage plate is Rochester's iconic comfort food — a plate loaded with two of your choice of macaroni salad, home fries, or baked beans, topped with a cheeseburger or hot dogs, smothered in 'meat hot sauce' (a spiced meat sauce unique to Rochester), mustard, and onions. It was invented at Nick Tahou Hots (founded 1918) and is now a trademark. The dish reflects Rochester's working-class industrial heritage. Rochester Public Market is another food institution — one of the largest and oldest public markets in the US, open year-round.
Can I rent part of my Rochester home on Airbnb?
Yes, with a Short-Term Rental Registration ($150/year) and property inspection. New York State sales tax and hotel unit fee apply — Airbnb and VRBO collect and remit these automatically. Rochester's STR market benefits from University of Rochester and RIT events, the Lilac Festival and Jazz Festival, Highland Park visits, and medical corridor visitors to URMC.
What are Rochester's best neighborhoods for homebuyers?
Park Avenue is considered Rochester's most desirable urban neighborhood — walkable, tree-lined, excellent restaurants and independent shops, Victorian housing stock. The South Wedge adjacent to Genesee Valley Park offers a bohemian arts character. Corn Hill is the oldest surviving residential neighborhood with pre-Civil War architecture near the Genesee riverfront. East Avenue has Gilded Age mansions. All are relatively affordable by national standards for their quality. The 19th Ward and EMMA neighborhoods are being revitalized with community investment.
Is Rochester's canal system relevant to modern development?
Rochester sits along the historic Erie Canal — the canal originally ran through downtown and its route is now the NY State Barge Canal (Erie Canal Thruway). The abandoned canal bed in western Rochester (the 'canal corridor') has been a development opportunity. The Genesee Riverway Trail connects the downtown High Falls district to the Lakeshore. The original Erie Canal towpath has been converted to recreational trails in Monroe County. Canal heritage adds to Rochester's tourism appeal.
Are there ADU programs to help with renovation in Rochester?
Yes — Rochester Rehabilitation Center and the JOSANA program provide rehabilitation assistance for owner-occupants. Monroe County HOME and CDBG funding supports housing rehabilitation including ADU creation. NY State's Homes and Community Renewal (HCR) offers programs for affordable housing creation. The City of Rochester's Department of Housing and Human Services administers local housing programs. Contact (585) 428-6888 for Rochester housing rehabilitation program information.
