Preapproved Accessory Dwelling (ADU) Plans

The City of Placentia City allows Accessory Dwelling Units (ADUs) and Junior Accessory Dwelling Units (JADUs) as a permitted use in residential zones and lots containing multi-family dwelling units. In compliance with State law, regulations are established in Chapter 23.73 of the Placentia Municipal Code. To help simplify the construction of ADUs in Placentia, the city has developed the pre-reviewed ADU program. Through this program the City is accepting available prototype plans for residents to use to build an ADU on their property. These plans can be submitted for plan check and can listed as available to utilize through the City's Development Services Department. The plans are intended to save homeowners the expense of having custom plans created and are intended for new construction only. The applicant will be responsible for providing a site plan for their specific property on which the ADU will be located and filling out all applicable portions of the prototype plans including project specific information on the coversheet. The required project specific information includes the APN number, the zoning, and the lot size, as well as the required setbacks among other information, such as the style selected, the window materials, and colors which will be used. The applicant will have the ability to download the site and floorplans plans using the links found on the City’s ADU webpage. Three sets of 24”x36” plans will still need to be submitted to the Building Safety Division for Plan Check Review. No construction is permitted without an approved Building Permit. All applicable plan check and development impact fees still apply. Contact the Planning Department for more information at (714) 993-8124.
