Lease vs rental agreement

Engraving of a thick stitched stack of pages beside a single loose sheet, an unmarked brass straight-edge laid between them — A thick stitched term and a single loose sheet: the difference is how long either side is committed.

60 / 30 days

A lease locks both sides for a term. A rental agreement renews itself until somebody gives notice.

The phrases are used interchangeably and they are not the same thing. A lease runs for a fixed term. A rental agreement is periodic — usually monthly — and continues until one side ends it with notice.

The difference, in one table

Line	Fixed-term lease	Periodic (month-to-month)
Duration	Set term, usually 12 months	Renews each period
Rent changes	Only at renewal	On statutory notice
Ending it	At term, or by breach	Notice by either side
Tenant flexibility	Low	High
Your vacancy risk	Concentrated at term end	Spread across the year

Everything else — deposits, entry, maintenance, habitability — is identical. The statute does not care what you called the document.

Notice periods on a periodic tenancy

The notice period is set by statute and can be asymmetric. California requires a landlord to give 60 days where the tenant has lived there a year or more, and 30 days below that, while the tenant gives notice at least as long as the period (Civ. Code § 1946.1, checked 2026-09-04).

Asymmetry is normal, not unfair

Statutes commonly require more of the landlord than of the tenant. Build it into your planning: on a periodic tenancy you are usually two months from vacant, not one.

Choosing between them

Seasonal market — fixed terms ending in spring or summer let far faster than ones ending in December.
Strong demand, rising rents — periodic lets you move rent on notice rather than waiting a year.
Tenant quality — a good tenant on a periodic tenancy is a tenant who can leave in 30 days.
Your own plans — if you may sell or occupy within the year, do not sign a 12-month term.

Price the flexibility rather than arguing about it: a periodic tenancy usually carries a small rent premium, and the turnover cost calculator will tell you how many months of that premium one extra vacancy eats.

Converting between them

01A fixed term that runs out with no action usually becomes periodic automatically.
02To keep a fixed term, send a renewal offer before the end date — see lease renewal.
03To convert a periodic tenancy to a term, sign a new lease; an amendment to the old one is enough where it names the new term.
04Never rely on the tenant "knowing" which one they are on. Put the current status in writing at every change.
