January in New York is when buildings work hardest—boilers run nonstop, windows sweat, and maintenance issues show up fast. These tips are tailored specifically for NYC apartments and co-ops, where small details make a big difference.

1️⃣ Watch for Window & Wall Drafts (Pre-War Buildings Especially)

If you live in a pre-war or older co-op, drafts often come through original windows, radiators, or wall AC sleeves. Use rope caulk, draft stoppers, or insulated window panels to keep heat in—without violating building rules.

📝 Tip: Most co-ops don’t allow permanent window modifications, but temporary insulation is usually fine.

2️⃣ Know Your Heat Rights (Before You Panic)

NYC buildings are legally required to provide heat:

• Oct 1 – May 31

• Minimum 68°F during the day when it’s cold outside

• 62°F overnight

If your apartment feels freezing, it might not just be “old building charm.” Document temps and contact management early—January is peak boiler-issue season.

3️⃣ Don’t Block Radiators (Even Accidentally)

Furniture, curtains, or radiator covers that aren’t ventilated can trap heat and make rooms colder—not warmer. Keep airflow clear and consider a reflective heat panel behind the radiator to push warmth back into the room.

4️⃣ Control Humidity to Prevent Mold

Winter condensation on windows is common in NYC apartments. Wipe down sills regularly and use a small dehumidifier if needed—especially in bedrooms and bathrooms. Co-ops do not love mold claims.

5️⃣ Test Smoke & CO Detectors (Boards Care About This)

Many NYC buildings have strict safety requirements. January is a good reminder to test detectors and replace batteries—especially if you use space heaters (where permitted).

🚫 Always check house rules before using space heaters.

6️⃣ Keep Pipes Warm—Even If Heat Is “Included”

If your kitchen or bathroom backs up to an exterior wall, open cabinet doors during cold snaps. Frozen pipes cause some of the most expensive building-wide damage—and boards remember who caused it.

7️⃣ Get Ahead of Spring Projects & Board Approvals

Planning renovations, sublets, or a sale in 2026? Start now.
NYC co-op boards move slowly, and contractors book early. January is the perfect month to:

• Review house rules

• Gather alteration agreements

•
