Late fees and grace periods for rent in Lynn

Massachusetts draws one of the country's brightest lines on late rent: no late fee, and no interest, until the rent is a full thirty days overdue. Any lease clause that charges sooner is void — including the inflated-rent-with-a-discount trick. The catch renters miss is that the eviction clock is a separate clock, and it can start on day one. This page keeps the two apart, at today's Lynn rents.

30 days

how overdue rent must be before any late fee or interest is lawful (c.186 §15B)

the most a lease can collect in late fees before day 30 — clauses that charge sooner are void

day 1

when the separate 14-day notice-to-quit clock can already start — the grace period doesn't delay it

No late fee until day 30 — in the statute's own words

General Laws c.186 §15B(1)(c) is one sentence: "No lease or other rental agreement shall impose any interest or penalty for failure to pay rent until thirty days after such rent shall have been due." That covers fees and interest alike, and it is not a default you can sign away — the Attorney General's landlord-tenant guide lists a late fee on rent less than 30 days late among the terms a Massachusetts lease may not contain at all. If your lease says a fee starts on day 5, that clause is void; you don't owe it. Source: M.G.L. c.186 §15B(1)(c) · Attorney General's guide to landlord and tenant rights

The "discount for paying on time" trick is the same fee in disguise

Some leases set an inflated rent and offer a "discount" if you pay by the first — so paying on the fifth costs you the "discount," which works exactly like a day-five late fee. Massachusetts treats that as what it is: a Housing Court reading of such a clause called it, in substance, a late charge prohibited by §15B(1)(c). MassLegalHelp's advice is concrete: pay the rent you actually agreed to, and if the landlord demands the extra, say in writing that the discount clause is illegal. Source: MassLegalHelp: Paying rent

After day 30 there is no dollar cap — your lease's own clause governs

§15B(1)(c) says when a penalty may start, not how large it may be: Massachusetts sets no statutory cap on the amount of a late fee once rent is 30 days overdue. Two things still bound it. A late fee is a contract term — if your lease has no late-fee clause, being late creates no fee at all, on day 30 or any other day; a landlord can't invent one mid-tenancy. And a fee only ever applies to rent actually 30+ days late — a lease can't compound it from day one retroactively.

The 30-day grace does not slow the eviction clock

The fee rule and the eviction rule are independent, and the asymmetry matters: a landlord who can't charge you a dime until day 30 can still serve a 14-day notice to quit for nonpayment (c.186 §11 for leases, §12 for tenancies at will) as soon as the rent is overdue. Waiting out the fee-free month is not a safe strategy — by day 30 a notice served on day 2 has already expired. The cure rights that can void that notice are on our eviction page; if the problem is the money itself, the assistance programs pay at exactly this stage. Source: M.G.L. c.186 §11

The two clocks, side by side

The average Lynn rent is $2,300/month as of June 2026 (how we compute this). What can lawfully happen as the days pass:

When	Fee clock (§15B)	Eviction clock (§§11–12)
Day rent is due	nothing — rent isn't late yet	nothing
Day 1 overdue	$0 — no fee, no interest, whatever the lease says	a 14-day notice to quit for nonpayment can already be served
Day 15 overdue	$0 — still nothing	a notice served on day 1 has expired; a court case can be filed
Day 30 overdue	first day a lease's late-fee or interest clause can charge — no statutory cap on the amount	the case may already be in court

That right-hand column is the reason the 30-day grace is not a payment plan. If the month's $2,300 isn't there, the move that actually protects the tenancy is on the eviction page (the cure rights that void a notice) and the rental-assistance page (the programs that pay at the notice stage) — not the fee-free calendar.

Honest caveat: these are smoothed market averages (Zillow's ZORI index — methodology), not your lease. The legal rules apply to your actual rent, whatever it is — the table shows the scale at typical Lynn rents.

If late rent is becoming the pattern

The fee rules are the surface; the useful pages are underneath: how eviction actually works here — the notices late rent can trigger and the cure rights that stop them; the programs that pay rent arrears, with income lines in real dollars and phone numbers; whether the rent itself is the problem — what Lynn rents demand of a budget; and what your ZIP actually costs (01905, 01902, 01904, 01901) if a cheaper unit beats a monthly fee.
