Understanding these rules can prevent disputes, ensure compliance with state law, and give tenants the time they need to adjust their budget or consider moving.<\/p>\n\n\n\n<p>In this blog, we\u2019ll explain what 30-day and 90-day notices mean, why they exist, the differences between them, and how both tenants and landlords can follow the law correctly.<\/p>\n\n\n\n<div

notice before increasing rent to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Give tenants time to plan for the higher rent or find alternative housing if needed.<\/li>\n\n\n\n<li>Prevent sudden and unfair rent hikes, protecting tenants\u2019 financial stability.<\/li>\n\n\n\n<li>Ensure compliance with state law and local ordinances, especially in cities with rent control.<\/li>\n<\/ul>\n\n\n\n<p>These notices are called \u201c<a href=\"https:\/\/www.complianceprime.com\/blog\/2023\/06\/06\/how-to-increase-roi-on-rental-housing-properties\/\">rent increase notices<\/a>\u201d, and the required notice period depends on the amount of the increase.<\/p>\n\n\n\n<p>The landlords also have control over the lease agreement tied to a property and one should know the <a href=\"https:\/\/www.complianceprime.com\/blog\/2025\/07\/17\/understanding-a-landlords-right-to-amend-a-lease\/\">right to amend a lease<\/a>, but only under the right conditions and with the right process.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>30-Day Notice<\/strong><\/h2>\n\n\n\n<p>A 30-day notice applies when:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The tenant has lived in the unit for less than one year or<\/li>\n\n\n\n<li>The rent increase is 10% or less of the current rent within the last 12 months<br><\/li>\n<\/ul>\n\n\n\n<p><strong>What this means:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The landlord must provide at least 30 days\u2019 written notice before the rent increase takes effect.<\/li>\n\n\n\n<li>This is common for smaller increases or short-term tenants.<\/li>\n\n\n\n<li>Tenants receive one month to adjust their finances or decide whether to continue renting.<\/li>\n<\/ul>\n\n\n\n<p><strong>For example:<\/strong> If a tenant pays $4,000 per month and the landlord wants to increase rent by $300 (7.5%), the landlord only needs to give a 30-day written notice because the increase is less than 10%.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>90-Day Notice<\/strong><\/h2>\n\n\n\n<p>A 90-day notice applies when:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The tenant has lived in the unit for one year or more and\/or<\/li>\n\n\n\n<li>The rent increase is more than 10% of the current rent within the last 12 months<strong><br><\/strong><\/li>\n<\/ul>\n\n\n\n<p><strong>What this means:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The landlord must provide at least 90 days\u2019 written notice before the rent increase takes effect.<\/li>\n\n\n\n<li>This gives tenants more time to respond to significant rent increases.<\/li>\n\n\n\n<li>It is designed to prevent large, sudden increases that could create financial hardship.<\/li>\n<\/ul>\n\n\n\n<p><strong>For example:<\/strong> If a tenant pays $1,000 per month and the landlord wants to raise rent by $125(12.5%), the landlord must provide 90 days\u2019 notice because the increase exceeds 10%.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Key Differences Between 30-Day and 90-Day Notices<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Factor<\/strong><\/td><td><strong>30-Day Notice<\/strong><\/td><td><strong>90-Day Notice<\/strong><\/td><\/tr><tr><td><strong>When it applies<\/strong><\/td><td>Increase \u2264 10% OR tenant &lt; 1 year<\/td><td>Increase &gt; 10% OR tenant \u2265 1 year<\/td><\/tr><tr><td><strong>Notice period<\/strong><\/td><td>At least 30 days<\/td><td>At least 90 days<\/td><\/tr><tr><td><strong>Purpose<\/strong><\/td><td>Small increase or short-term tenant<\/td><td>Large increase or long-term tenant<\/td><\/tr><tr><td><strong>Tenant preparation time<\/strong><\/td><td>Shorter<\/td><td>Longer, to plan finances or relocate<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>In short, the size of the rent increase and the tenant\u2019s length of stay determine whether 30 or 90 days\u2019 notice is required.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What Happens If the Notice Is Not Properly Given<\/strong><\/h2>\n\n\n\n<p>If a landlord fails to provide the proper notice:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The tenant may refuse to pay the increased rent until the notice period is correctly observed.<\/li>\n\n\n\n<li>Legal disputes may arise, and landlords could face penalties or enforcement actions.<\/li>\n\n\n\n<li>The landlord may need to resend the notice and delay the rent increase until compliance is achieved.<\/li>\n<\/ul>\n\n\n\n<p>For tenants, understanding the correct notice period protects them from illegal rent increases.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Tips for Compliance<\/strong><\/h2>\n\n\n\n<p><strong>For Landlords:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Determine whether the rent increase is above or below 10% of the current rent.<\/li>\n\n\n\n<li>Check how long the tenant has lived in the unit.<\/li>\n\n\n\n<li>Provide a written notice specifying the amount, effective date, and applicable laws.<\/li>\n\n\n\n<li>Review local rent control laws, as some cities may require longer notice periods.<br><\/li>\n<\/ul>\n\n\n\n<p><strong>For Tenants:<\/strong><\/p>\n\n\n\n<ul
