Verify the lease, law and service before relying on a date

There is no universal 30-day termination formula. CalcSpan applies only the exact period, service date, first-day convention and endpoint adjustment entered from the lease and current state or local rule.

Read before relying

Context matters.

  • State and local law, the lease, tenancy length, rent-payment period, cause, rent control and the party giving notice can all change the period.
  • Service method and proof can determine when counting begins. A mailed, posted, hand-delivered or electronically delivered notice may not share the same effective date.
  • Landlord termination, eviction, subsidized housing and protected-tenancy situations need a dedicated current-law review; this result is not legal advice or a valid notice form.

Questions answered

What to know before using the result.

Why is there no universal 30-day answer?

Notice can vary by state, city, lease, tenancy length, rent-payment period, party giving notice and reason for termination. Enter the exact period from the controlling lease and current local rule.

Why does service method matter?

A rule may define when hand delivery, mail, posting or another permitted method becomes effective. Counting from the date written on a notice instead of the legally effective service date can produce the wrong endpoint.

Can this calculate an eviction or subsidized-housing notice?

No. Landlord termination, eviction, HUD-assisted or regulated housing and protected-tenancy situations are blocked because they can have additional grounds, form, service and review requirements.
