Request for Clarification Deadline April 18, 2023 1. Summary and Background
The City of Claremont (City) is seeking professional design services for the preparation of
Accessory Dwelling Unit (ADU) standard plans that would be pre-plan checked by the City and
permit-ready, free to use to residents of Claremont. The City intends to purchase the plans from
the selected designer and make them available to the public free of charge as an incentive to
promote the construction of smaller ADU housing that is more affordable by design due to the
small size of the units. Three (3) different plans are needed that include interior unit sizes of
approximately 500 square feet (SF), 600 SF, and 750 SF, with 1- and 2-bedroom units designed
in a residential architectural vernacular consistent with the single-family neighborhoods in
Claremont. The standard plans would include reverse floor plans for each of the units, and at
least three (3) options for different exterior treatments, including different materials and colors,
accents and ornamentation. At least one (1) plan must include a Universal Design/Accessibility
floor plan design option with a step-free entrance, sufficient maneuvering space for wheelchair
in bedroom, kitchen, living room, and admittance to a full bathroom, and ample room to pass
through 32-inch doorways. The standard design plans delivered to the City will become the
intellectual property of the City upon delivery.
2. Project Deliverables
The project deliverables include:
A. Rough drafts and a final (following staff review and approval) of a single-story ADU plan
in 24" x 36" size for one each of;
Approximately 500 square feet, one-bedroom unit,
Approximately 600 square feet, one-bedroom unit, and
Approximately 750 square feet, two-bedroom unit.
B. A narrative statement describing the architectural style of each prototype ADU design
and the alternative exterior treatments and architectural accents for each unit type.
C. Each unit is to include a full kitchen, washer/dryer hookups, bathroom, bedroom(s), and
living area. Each unit must comply with the City's ADU Development Standards, CMC
Chapter 16.33.060.
D. Three (3) complete building plan sets prepared in conformance with the 2022 California
Building Standards are required that include specifications and details for the foundation
(slab on grade or pier and beam), structural framing, roofing, siding, interior drywall
finishing, plumbing, gas, electrical, and utility connections.
E. At least one (1) plan must include a Universal Design/Accessibility floor plan design
option with a step-free entrance, sufficient maneuvering space for wheelchair in
bedroom, kitchen, living room, and admittance to a full bathroom, and ample room to
pass through 32-inch doorways.
F. Three (3) complete reverse floor plan sets are required that include specifications and
details for the foundation (slab on grade or pier and beam), structural framing, roofing,
siding, interior drywall finishing, plumbing, gas, electrical, and utility connections.
G. Energy calculations are required for each master plan prototype unit that includes an
averaging of all four elevations and sides of the building.
H. Building plans that include at least three (3) different options for varied design themes
utilizing different architectural treatments for each prototype plan using different
materials, architectural accents and ornamentation that are intended to generally be
compatible with the main residence and in a similar architectural vernacular that is
common to Claremont's single-family neighborhoods. This architectural vernacular
includes, but is not limited to, Mission and Spanish Colonial Revival, Tudor,
Contemporary, Craftsman, California Ranch, and Victorian. Please refer to the City of
Claremont Architectural Design Guidelines (Exhibit C) for a detailed overview of the
City's existing architectural styles.
I. Floor plans (and reverse floor plans) and elevations of each unit type with alternative
treatments utilizing different materials, architectural accents and ornamentation.
Vehicular parking is not requirement, but is strongly encouraged. Schematics for on-site
parking are to be included as an alternative for each unit type.
J. Color renderings that are representative of each of the different unit designs. These
high-quality illustrative color renderings are intended to be utilized to promote the ADU
plan program on City handouts, brochures, websites, etc.
K. Clearing of comments and corrections through the building plan check process to ensure
each unit type and alternative plan treatment obtains an approved building permit. A
minor building permit plan check for site plan review would be required for each ADU to
ensure the unit meets setback standards, separate access requirements, parking,
outdoor lighting, and utility connection plans.
L. Electronic digital copies of all final approved plans, plan documents, and color
renderings are a requirement.
Note: Refinements and/or adjustments to these deliverables, including consideration of fewer
design alternatives, smaller unit sizes, or the like, may be negotiated between the selected
design consultant and the City if there are substantial cost savings and/or time saved in the
preparation of the plans. Please prepare and organize your proposal based on the requirements provided below. Any
other information you would like to include should be placed in a separated section at the back
