Your landlord must give you 30 days' notice of a rent hike if your lease is periodic and month-to-month or less. You're entitled to 30 days' notice if the increase is 10 percent or less and 60 days' notice if it's over 10 percent for other lease types. Your landlord must use the lowest rent you paid over the last 12 months.
California has a relatively short time in which to enforce a valid mechanics lien. In California, it is required that a mechanics lien be enforced within 90 days from the date on which the lien was recorded. If this 90-day period passes without an action being commenced to enforce the lien, the lien expires.
(Engineers have a 60-day grace period. Land Surveyors and Geologists have a 30-day grace period.) The grace period only applies to the fee you have to pay to renew your license. If you do not pay your renewal fee by the expiration date, your license will be considered expired.
