Accessory Dwelling Units (ADUs) – 3D Models and Floor Plans for Public Use
In March of 2019, the State of California released a Notice of Funding Availability for the Senate Bill 2 (SB2) Planning Grants Program. Senate Bill 2 was part of a 15-bill housing package aimed at addressing the State’s housing shortage and high housing costs. Specifically, it establishes a permanent source of funding intended to increase the affordable housing stock in California. The minimum grant award for Del Mar through the SB2 Grant Program was $50,000, and the maximum was $160,000.
To develop the City’s grant application, staff analyzed the City’s priority housing projects based on the adopted “22 in 5” work program (how to build 22 affordable units in 5 years) to identify eligible grant activities. After analyzing the projects within the “22 in 5” work program, staff and the Housing Liaisons confirmed that three projects were eligible for funding based on the standards set by the State Department of Housing and Community Development (HCD). One the selected projects was intended to incentivize Accessory Dwelling Units (ADUs) by developing three Accessory Dwelling Unit (ADU) floor plans to be licensed to the City for public use (floor plan only, no construction drawings).
What is an ADU?
As set forth in California Government Code section 65852.2, an Accessory Dwelling Unit (ADU) is a smaller (detached or attached) secondary dwelling unit with complete, independent living facilities (kitchen and bathroom) that is located on the same parcel as a primary dwelling unit (existing or proposed). The ADU can be located within or attached to a single dwelling unit, within a multiple dwelling unit building, or in a separate detached structure.
Sample ADU Floor Plans and 3D Renderings
Below you will find three separate and distinct ADU floor plans that adhere to both State mandates and the Del Mar Municipal Code. The sample floor plans, which were developed by Stephen Dalton Architects (SDA), are only floor plans and will still require formal construction drawings, however, they do provide the residents of Del Mar a jump-start in beginning your ADU project. The three samples, as detailed below, vary in size from 446 square feet, to 955 square feet and are all designed to be fully ADA accessible.
Frequently Asked Questions (FAQ)
How to Apply
State law requires a streamlined, ministerial review process for proposed ADUs and JrADUs that exempts all such applications that meet each of the specified objective review standards from discretionary permit review, including design review.
Applicants will need to fill out an ADU Application Packet (Fillable PDF), pay associated fees (PDF), and submit development plan sets. Submitted plans that meet the requirements in Del Mar Municipal Code Section 30.91 will be approved within 60 days of a complete application submittal. If the ADU or JrADU permit application is processed at the same time as a permit application for a new primary dwelling unit on the lot, the City may delay acting on the ADU or JrADU application until the City acts on the permit application for the primary dwelling unit.
