Bathroom fan installations involve electrical wiring and ensuring this is monitored and inspected is vital to safety. <\/p>\n\n\n\n<p class=\"has-central-palette-1-background-color has-background\"><strong>However, if no re-wiring or electrical maintenance is needed to install your new fan, in other words, you are simply unplugging one fan and plugging in a new one, then you may not need to obtain a permit. <\/strong><\/p>\n\n\n\n<p>As regulations pertaining to whether or not you need a building permit to install an exhaust fan in your bathroom vary based on location, you should contact your local building department regarding their policies and guidelines. They can also assist you with other\/follow-up permit-related questions.<\/p>\n\n\n\n<p>Listed below are examples of permit guidelines from two different locations in the US. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">San Diego, California<\/h3>\n\n\n\n<p>Here, homeowners and contractors have the option to obtain something known as a &ldquo;<a rel=\"noopener\" href=\"https:\/\/www.sandiego.gov\/development-services\/permits\/simple-permits\" target=\"_blank\" data-lasso-id=\"2073\">simple permit<\/a>&ldquo;. This is a mechanical, electrical, and plumbing permit that is granted for simple installations, including the installation of a bathroom exhaust fan. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Superior, Wisconsin<\/h3>\n\n\n\n<p>A permit is required in this city when upgrading\/adding electrical circuits, fixtures, equipment, and device (<a rel=\"noopener\" href=\"https:\/\/www.ci.superior.wi.us\/613\/Permits---Needed-or-Not\" target=\"_blank\" data-lasso-id=\"2074\">Permit Guidelines<\/a>). Installing a bathroom fan falls into this category, which means a permit is required prior to the installation of a bathroom fan in Superior. Furthermore, it means that if you have an existing fan and want to replace it with a more feature-heavy option, you will need a permit. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Do I Apply for a Permit?<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"563\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/How-To-Applay-1.jpg\" alt=\"\" class=\"wp-image-3335\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/How-To-Applay-1.jpg 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/How-To-Applay-1-300x169.jpg 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/How-To-Applay-1-768x432.jpg 768w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"563\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/How-To-Applay-1.jpg.webp\" alt=\"\" class=\"wp-image-3335 lazyload\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/How-To-Applay-1.jpg.webp 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/How-To-Applay-1-300x169.jpg.webp 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/How-To-Applay-1-768x432.jpg.webp 768w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/How-To-Applay-1.jpg\" id=\"mv-trellis-img-3\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>To apply for a building permit, first, contact your local building office and provide details regarding your project. They will be able to tell you based on the details you provide whether or not it is necessary for you to obtain a permit and which permit you to need to apply for.<\/p>\n\n\n\n<p>If a permit is required for installation, you will be given an application form that outlines requirements, additional permits, documents, or other information necessary to obtain a building permit. <\/p>\n\n\n\n<p>After completing the application for the building permit, submit the application to the indicated address or email address and pay any required fees. You will need to apply for a permit before you begin the installation process. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can Someone Apply on My Behalf?<\/h3>\n\n\n\n<p class=\"has-central-palette-1-background-color has-background\">If you hire a contractor to install your appliance, <a href=\"https:\/\/thetibble.com\/who-pulls-permits\/\">they will usually handle the application for a building permit<\/a> themselves. However, if you plan to perform the installation by yourself without the aid of a contractor, you as the homeowner will need to apply for a permit. <\/p>\n\n\n\n<p>Continue reading to learn what information the individuals issuing the permit will want to know about your project, various costs associated with receiving an installation permit, the typical timeline for a permit to be approved, and who is authorized to install your exhaust fan. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Will They Want to Know About the Installation?<\/h2>\n\n\n\n<p>To receive a building permit, you will be required to provide architectural, structural, mechanical, and electrical information pertaining to your bathroom.

Additionally, they are often able to be paid online using a credit\/debit card.

If you need any new ductwork in the bathroom, it is <a href=\"https:\/\/thetibble.com\/who-to-hire-replace-bath-fan\/\">recommended to hire a plumber or HVAC specialist<\/a>. <\/p>\n\n\n\n<p>It is important to note that if you obtain the required permit(s), you as the homeowner are also able to install the bathroom fan on your own. However, it is safer to hire an experienced electrician as working with electrical circuits can be dangerous. <\/p>\n\n\n\n<p>If you think it is troublesome to try to obtain a permit for installing a bathroom fan, please don&rsquo;t just decide not to install one. There are so many (mostly older) homes, that neglect the exhaust fan and consequently suffer many other problems.

An undersized duct will make the fan much louder and reduce its capacity to move air.<\/p>\n\n\n\n<p>The general recommendation is to use at least the same size duct that is on the bath fan housing connector. If the duct run is longer than 20 ft consider going up one size.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Duct Type<\/h3>\n\n\n\n<p>Rigid metal or PVC duct is preferable, If the duct run is short a<a href=\"https:\/\/thetibble.com\/what-kind-duct-bath-fan\/\"> flex duct can be used<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Duct routing<\/h3>\n\n\n\n<p>Find the <strong>shortest<\/strong> and <strong>straightest<\/strong> path from the <strong>fan<\/strong> to the <strong>termination<\/strong> point. The fewer turns and the shorter the duct is the more efficient the entire system will be.
