A large share of homes around Keuka Lake are old: farmhouses on the hills, village homes in Penn Yan and Hammondsport, and lake cottages that started as summer camps and grew one addition at a time. Older homes often have more character and better sites than new construction. They also tend to have several aging systems at once, and a few hazards that newer homes don’t.

This guide covers what to look for in an older lake-area home, the health and safety issues tied to age (lead, asbestos, radon, carbon monoxide), the systems that most often need work, and how permits and codes come into play when you renovate.

Why older homes are different here

Two things set older Keuka homes apart from older homes generally:

Seasonal origins. Many cottages were built for summer use, with little insulation, shallow plumbing, small septic systems, and heating added later (or never). See our guide to converting a seasonal cottage to year-round use.
The setting. Steep lots, lake humidity, freeze-thaw cycles, and long or private access roads all add wear and complicate repairs.

None of this is a reason to avoid an older home. It’s a reason to inspect carefully and budget honestly.

Health and safety issues tied to age

Lead paint (homes built before 1978)

Lead-based paint was banned for residential use in 1978, and it’s common in older homes. Under federal law, sellers and landlords of most pre-1978 housing must disclose known lead-based paint and hazards, provide the EPA pamphlet Protect Your Family From Lead in Your Home, and give buyers an opportunity (generally 10 days, which can be waived) to have the home inspected for lead (EPA real estate disclosure rule).

If you hire someone to renovate, repair, or paint a pre-1978 home, EPA’s Renovation, Repair and Painting (RRP) Rule requires the contractor to be a Lead-Safe Certified firm using lead-safe work practices. The rule generally doesn’t require a homeowner doing unpaid work on their own home to be certified, but it does apply if you rent out all or part of the home. EPA’s guidance for do-it-yourselfers explains how to work safely. Sanding, scraping, and demolition of painted surfaces create the most hazardous dust.

Asbestos

Older homes may contain asbestos in pipe and boiler insulation, some floor tiles, siding, roofing, and other materials. Material in good condition that isn’t disturbed generally isn’t a hazard; the risk comes when it’s damaged or disturbed during work. EPA’s asbestos guidance for homeowners recommends leaving suspect material alone and hiring trained professionals to test and, if needed, repair or remove it. In New York, asbestos abatement is regulated by the state Department of Labor, so check with your town’s code office before demolition or renovation that may disturb suspect materials.

Radon

Radon is a naturally occurring radioactive gas that can enter homes from the ground. The New York State Department of Health’s radon program recommends testing, offers low-cost short-term test kits to state residents, and recommends fixing a home when radon levels are 4 picocuries per liter (pCi/L) or higher. Testing is the only way to know. A test in the lowest lived-in level of the house is a reasonable part of a home purchase. For town-by-town state data, testing steps, and mitigation costs, see our radon testing guide.

Carbon monoxide

Older homes often have fuel-burning boilers, furnaces, water heaters, fireplaces, and wood stoves. New York’s Amanda’s Law requires carbon monoxide detectors in one- and two-family homes that have fuel-burning appliances or an attached garage. Make sure they’re installed and working, and have fuel-burning equipment and chimneys inspected regularly. For wood and pellet stoves, see our wood stove and chimney guide. Our generator guide covers CO risks during outages.

The systems that most often need work

Electrical

Old wiring may not handle modern loads. Watch for:

Small service capacity (older homes may have far less service than a modern house with heat pumps, an EV charger, and a full kitchen).
Knob-and-tube wiring or ungrounded circuits.
Outdated panels, fuses, or amateur additions, especially in cottages wired one project at a time.
No GFCI protection near water: kitchens, baths, outdoors, and boathouses.

Some insurers restrict coverage or pricing for certain older wiring types. A licensed electrician’s evaluation is worth it before buying an older home.

Heating

Many older lake homes have aging oil or propane boilers or furnaces, space heaters added over the years, or no central heat at all. Ask the age of the system, its service history, and what it cost to run last winter. Our heating systems and heating costs guides cover fuel choices and programs.

Oil tanks

If the home heats (or once heated) with oil, find out where the tank is, how old it is, and whether there’s an abandoned tank, including a buried one. Leaks are costly to clean up. Petroleum spills in New York generally must be reported to the Department of Environmental Conservation spill hotline at 1-800-457-7362 within two hours of discovery (DEC spill reporting).

Plumbing

Older homes may have galvanized steel pipes that corrode from the inside, old lead service lines or lead solder, or plumbing added in unheated crawl spaces. In former cottages, look for lines that run where they’ll freeze. See our winterizing guide.

Septic and well

Old septic systems may be undersized, poorly located, or missing records. Every property transfer in the Keuka watershed requires a septic inspection, and adding bedrooms requires a wastewater permit. See our septic guide and KWIC inspection guide. For water, see our well water guide.

Roof, windows, and water

Lake weather and freeze-thaw cycles are hard on roofs, flashing, gutters, and windows. Small leaks become rot, mold, and structural damage. Ask the roof’s age and look for staining in attics and ceilings. Stains near the eaves can mean ice dams; see our ice dams, roof snow loads, and frozen pipes guide.

Foundations and drainage

On hillside lots, water drains toward the house unless it’s directed away. Look for basement water, efflorescence on walls, cracked or bowing foundations, and sagging floors. Older cottages sometimes sit on piers or stone foundations that were never meant for year-round loads.

Insulation and moisture

Many older homes have little insulation. Adding it improves comfort and cuts heating costs, but it changes how moisture moves through walls and attics. Get advice before sealing up an old house, especially near the water.

Renovations, permits, and codes

New York’s Uniform Code and Energy Code apply to renovation work, and your town’s code enforcement officer handles building permits. Under the state’s Energy Conservation Construction Code, additions and alterations generally must meet current requirements for the parts of the house being changed, while unaltered parts usually don’t have to be upgraded.

Around Keuka, a few other approvals come up often:

Septic. Adding bedrooms or changing a building’s use requires a KWIC Wastewater System Construction Permit.
Zoning. Older lake homes often don’t meet today’s setbacks. Many towns let a nonconforming building stay but restrict expanding it in ways that increase the nonconformity. See our setbacks and zoning by town guide.
Shoreline. Work near the water may need state or town permits. See our shoreline rules guide.

Unpermitted past work is common in older homes. Ask the town whether permits and certificates of occupancy exist for additions, and ask your attorney about the implications.

Budgeting

We don’t publish typical repair costs because they vary widely by house and contractor, and we haven’t found a local source we trust that publishes them. Get written estimates for big items (roof, electrical, heating, septic) before you finalize your offer, and keep a reserve for the surprises older homes always produce.

What to have on hand

Testing and safety basics for an older home (links go to Amazon search results):

A short-term radon test kit. DOH’s own low-cost kit is also a good option.
An EPA-recognized lead test kit for a quick check before small projects. Larger jobs need an RRP-certified contractor.
Carbon monoxide alarms, required in New York homes with fuel-burning appliances

Frequently asked questions

Do I need to worry about lead paint in an older Keuka home?

If the home was built before 1978, lead paint is possible. Sellers must disclose known lead hazards and give buyers a chance to test. Contractors working on pre-1978 homes must follow EPA’s lead-safe rules.

Should I test for radon?

Yes. Testing is the only way to know. New York DOH recommends fixing homes at 4 pCi/L or higher and offers low-cost test kits.

Can I keep my old cottage’s footprint if it’s closer to the lake than zoning allows?

Often the existing building can stay as a nonconforming structure, but expansions that increase the nonconformity are usually restricted. Check your town’s zoning law and talk to the code officer.

Will an old house be harder to insure?

It can be. Roof age, wiring type, heating systems, and oil tanks affect pricing and eligibility. See our insurance guide.

Do I need a permit to renovate?

Many renovations require a building permit from your town, and adding bedrooms requires a KWIC wastewater permit. Ask the code office before you start.
