18.411.010 Accessory Apartment Conditional Use Permit Standards
Changing an existing garage or a portion of your house into an apartment takes considerable planning and may be cost prohibitive. There are many websites with information such as: https://www.garageconversion.org/garage-conversion-gallery/convert-garag...
“Converting a garage into an apartment isn’t an easy task and unless you’re a professional it isn’t something you want to undertake. Many times when homeowners attempt to convert a garage into an apartment, they end up with an illegal garage conversion. Knowledgeable contractors will know the proper coding and set up your garage into an apartment correctly. Having it converted legally to an apartment depends on the size of your property and the location of the garage on the property to determine minimum setbacks from your property line.The distance from the nearest sewer line, water supply, power lines, interior finishes such as flooring and cabinets can also make a big impact on the price. The average garage to apartment conversion cost varies widely between $40,000 and $70,000.”
Please contact the Planning/Zoning Department before undertaking an accessory apartment project whether you are converting an existing structure or building a new structure. We can help you comply with the conditional use requirements.
