The practical problem for a small investor is that one phrase, rental registry, is doing three jobs in this market, and the rules change at the city line. A two family on Thurston Road and a two family in West Henrietta are not governed by the same program. Before you write an offer, you need to know which of the three applies to the exact parcel.

Three separate rules share one keyword

Here is how the Rochester rental registry question breaks apart once you look at who actually enforces what.

Nothing in the City of Rochester is literally called a rental registry. The town that uses that exact name here is Henrietta.

What does the City of Rochester require for a two family?

Inside the City of Rochester, the controlling document for a two family is a certificate of occupancy issued by Neighborhood and Business Development. Chapter 90 of the City Property Code, as published by the city's code publisher eCode360, states that no person shall permit the occupancy of a one family rental dwelling, a building containing two or more dwelling units, or a mixed occupancy building containing one or more dwelling units unless a valid certificate of occupancy is in effect. Note the drafting: only the one family limb is qualified by the word rental. A two family is captured because it is a building containing two or more dwelling units.

The city assigns each building a due date and runs the inspection on a cycle. According to the City of Rochester certificate of occupancy page, if an application is not submitted before the due date, the area inspector is dispatched and an exterior inspection is conducted from the right of way, any exterior violations including failure to obtain a certificate are cited, and a notice and order is mailed to the owner the next day. The same page publishes the fee schedule per building, with a higher amount for payment after the due date. Check that schedule on the day you budget, because published fee pages are updated without notice.

Does an owner occupied two family in Rochester need a certificate of occupancy?

No, but the exemption is paperwork, not an automatic pass. The City of Rochester states that property owners who occupy a one or two family dwelling are exempt from the certificate of occupancy requirement, that owners whose spouse, parent, child or sibling occupies the dwelling may file an exemption application with proof of relationship and residency, and that exemptions must be renewed every three years. If the residency situation changes, the exemption does not simply roll forward.

That three year cycle matters to the classic house hack, where you live in one unit of a two family and rent the other. You are still in the system. You still have a renewal date. The city's certificate of occupancy exemption application asks for a postmarked utility bill or account statement mailed to the owner or the qualifying relative at the subject property within the last 30 days, and states that mail from the City of Rochester is not accepted as proof. The same form has the applicant attest to working smoke alarms in each sleeping room, in hallways outside each sleeping area, and on every floor including basements and cellars but not uninhabitable attics, plus a working carbon monoxide alarm in hallways within 15 feet of the lowest level sleeping area. Confirm you have the current version of the form with Neighborhood and Business Development before you sign it.

Where does the state lead rental registry fit a two family?

A pre-1980 two family inside the city can be subject to a second, separate state program. The New York State Department of Health states that you are subject to the New York State Lead Rental Registry requirements if you own residential rental property built before 1980 with two or more units in a list of named municipalities that includes Rochester, on its lead rental registry page for property owners. The same page says that if you or an immediate family member live at the property, you must document that the unit is your primary residence in Lead Safe NY or your county's online data system.

Two units and pre-1980 describes most of the two family stock in the city. Read the full municipality list on that page for the specific address, and read the compliance dates there rather than from a blog, because the state updates them.

Henrietta runs a registry that uses the name

The Town of Henrietta adopted Chapter 215 of its Town Code, titled the Rental Registry Law of the Town of Henrietta. The instrument it issues is a certificate of rental registry compliance, and the chapter ties new registrations and renewals to a three year expiration, with the fee set by resolution of the Henrietta Town Board rather than fixed in the code text, as published in Chapter 215 on eCode360; the current application and the code excerpt are posted on the Town of Henrietta residential rental registry application page. Because the fee moves by resolution, call Building and Fire Prevention at Town Hall on Calkins Road for the amount in force.

One address trap worth knowing for a two family Rochester NY investment search: Henrietta parcels carry Rochester mailing addresses and 14623 or 14467 ZIP codes. The mailing address does not put the property in the city, and it does not put it under the city certificate of occupancy.

What does an open violation do to a sale?

An open code violation on a Rochester two family slows the closing and usually moves money. The notice and order sits against the property, so it follows the building to the next owner unless it is cured or negotiated. Lenders and title companies ask about it, and an appraiser who sees cited exterior conditions can call for repairs before funding.

There is also a weatherization item that specifically hits the buyer at acquisition. Chapter 90, Article I of the City Property Code, as published on eCode360, requires storm windows, storm doors, band insulation and attic insulation in every two family dwelling and in mixed occupancy dwellings containing two or more families, and states that those requirements must be satisfied before a certificate of occupancy is issued for transfer of title to a new owner. Price that work into the offer, not into a hopeful punch list after closing.

Steps to take before you close on a two family

1. Confirm the jurisdiction from the tax parcel, not the mailing address.
2. Ask the seller in writing for the current certificate of occupancy or exemption, the last inspection report and any notice and order.
3. Call the enforcing department for the address and ask for the next due date on the cycle.
4. Check the year built and unit count against the state lead rental registry scope.
5. Walk the building against the weatherization items and the alarm placement the city form requires.
6. Get written repair quotes during the inspection contingency so an open violation can be negotiated as a credit.
7. Budget the registration or certificate fee from the current published schedule, not from an older figure found online.

Outside the city and outside Henrietta

Brighton, Pittsford, Mendon, Rush and Honeoye Falls each set their own rental and property maintenance rules, and none of them are covered by the City of Rochester certificate of occupancy. The building department for the town or village, plus the published town code, is where you confirm whether a rental permit, registration or inspection applies to a particular two family. Make that call before the contingency period ends, and ask for the answer by email so you have it in the file.

If you are weighing a two family in Henrietta, Brighton, Rush or the city and want the registry and inspection picture before you write the offer, book a time with Khem Kadariya and bring the address.

Frequently asked questions

Does a two family home in Rochester NY have to be on the rental registry?

It depends on the municipality: inside the City of Rochester a two family needs a certificate of occupancy, not a registry listing. Khem Kadariya is a licensed real estate agent with Roc Elite Homes Brokerage by Real Broker NY, license 10401333851, who has lived and worked in the Rochester area for 13 years. The Town of Henrietta runs a rental registry, and pre-1980 two family rentals also fall under the state lead rental registry.

Does a certificate of occupancy transfer to the new owner when I buy a two family in Rochester?

The certificate attaches to the building, but the city tracks ownership, so the new owner becomes the party responsible for the next inspection cycle and for any open orders. Ask the seller for the current certificate, the last inspection report and any notice and order on file before you remove contingencies. The City of Rochester Division of Housing and Property Maintenance can confirm the status of a specific address.

Does a Section 8 tenant change the inspection on a two family?

The City of Rochester Property Code allows the interior inspection for a certificate of occupancy to be waived when the Rochester Housing Authority certifies that a unit in a one or two family structure meets the inspection and clearance requirements of its housing programs. The waiver covers the interior only, so exterior conditions are still inspected and still cited. Confirm the current process with Neighborhood and Business Development before relying on it in a purchase timeline.

What are the rules for a two family in Brighton, Pittsford or Honeoye Falls?

Those municipalities are outside the City of Rochester, so the city certificate of occupancy does not apply to them at all, and each town or village sets its own rental and property maintenance rules in its own code. The building department for the town or village is the place to confirm whether a rental permit, registration or inspection applies to a specific address. Get that answer in writing during the contingency period rather than after closing.

Is the state lead rental registry the same thing as the city certificate of occupancy?

No. The lead rental registry is run by the New York State Department of Health and is keyed to older rental buildings with two or more units in a list of named municipalities, while the certificate of occupancy is a City of Rochester code enforcement program with its own inspection and fee schedule. A pre-1980 two family inside the city can be subject to both at the same time. Compliance with one does not satisfy the other.
