Bid Title: Prototype Designs for Accessory Dwelling Units
Category: Professional Services
Status: Closed

The City of Seaside is gearing up for a major push to encourage development of Accessory Dwelling Units (ADUs) in existing residential neighborhoods. Building ADUs is seen as a relatively inexpensive way to increase the City’s housing supply, address the current housing crisis, and assist existing homeowners by providing additional rental income. To encourage ADU development the City is in the process of removing permit fees, providing low-interest loan options and streamlining the plan check process. The City is also in the process of preparing details for the allocation of water credits that have been set aside exclusively for ADUs. To further promote ADUs the City wishes to also design and complete several demonstration ADU projects that will highlight detached ADUs, Junior ADUs and attached garage conversion ADUs. 

Depending on the sites selected, the proposed architectural contract will include the completion of three or more of the following distinct design tasks:

  • -           Schematic and working drawings for the repair or remodeling of one or two existing homes. The extent of the rehabilitation work on the existing homes remains to be determined, but at a minimum, will require upgrades to provide state-of-the-art water conservation appliances and fixtures.
  • -          The incorporation of a Junior ADU into one of the houses to be remodeled.
  • -          The design of a prototype 500 square foot detached ADU to be built on one or two demonstration sites.  
  • -          An attached garage conversion ADU for an existing home.
  • -          The development of a manufactured ADU demonstration home. The selected architect would assist in the selection of the manufacturer of a State-approved manufactured ADU, and prepare the site plan and foundation work required for its installation.  

The detached ADU should be a one-bedroom, one bath, design of approximately 500 square feet in size. It should be high quality but simple in design with high energy efficiency, long-lasting materials and ease of construction in mind. Incorporated into the design should be state-of-the-art water conservation appliances and fixtures, landscaping materials and equipment and a gray water and/or water catchment system, both as a water conservation demonstration and as a way to minimize the need for additional water allocation by the City. The ADUs will utilize the same water meters currently in place for the existing homes.

In keeping with the Seaside Housing Element’s Goal H-7 Policy to encourage universal design, the ADUs should meet universal design standards, if practical given site conditions. This should provide, at a minimum, wheelchair access to the front and rear entrances, in the hallways and doorways, and with appropriate grab bars in the bathroom.

It is the City’s intention that the completed working drawings for the detached ADU would be a prototype design, with several design options, that could then be pre-approved by the City’s Building Department and then made available, free of charge, to local homeowners as encouragement to build. The completed working drawings would become the property of the City to be used by homeowners on multiple future sites
