What does this &quot;no waiver&quot; clause mean?
<p>In a resedential lease, what does this paragraph mean?</p>

<blockquote>
  <p><strong>No Waiver.</strong>  The failure of either party to insist in any instance upon  the strict keeping, observance or performance of any provision of
  this Lease or to exercise any election in this Lease shall not be
  construed as a waiver or relinquishment for the future of such
  provision, but the same shall continue and remain in full force and
  effect. No waiver or modification by either party of any provision of
  this Lease shall be deemed to have been made unless expressed in
  writing and signed by the party to be charged. The receipt and
  retention by the Landlord of Rent with knowledge of the breach of any
  provision of this Lease shall not be deemed a waiver of such breach.</p>
</blockquote>

<p>Also is this considered a clause or provision? </p>

<p>It means that if one party breaks the lease and the other party chooses not to enforce their rights in relation to the breach, it doesn't mean that they won't enforce their rights the next time that provision is breached <em>unless</em> they agree that in writing thereby changing the agreement.</p>

<p>Which may just be the longest coherent sentence I have ever written.</p>
