Planning a custom home in Claremont
A replacement house in Claremont begins with two different records: the property’s design-review context and the construction documents. The City’s packet separates historic-register status from ordinary architectural and site-plan review, and identifies a rural site analysis for Residential Rural zones. Those distinctions belong in the first design conversation, not after a proposal is priced.
KB Remodeling takes new-home inquiries from owners planning here. Share the lot and the project; KB reviews scope, licensing and location for each inquiry before suggesting a next step.
Planning sequence
01
Identify the design-review route
The Planning permits page describes Design Review for new construction, exterior changes and changes in site features. Ask Planning which review type and other land-use applications apply to your actual scope.
Official resource: Claremont · Planning permitsCity-wide guidance · Passage checked
02
Resolve historic and rural questions before drawings
The application asks whether the property is on the historic register and includes a Rural Claremont site analysis for Residential Rural zones only. Bring the parcel designation and existing-building record; neither question is answered by a Claremont mailing name.

03
Prepare the exterior as well as the floor plan
The packet lists site plans, elevations, floor plans, window and door details, exterior veneers, a color/material board and landscape information. Agree with staff which checked items and current delivery format your application needs.

04
Coordinate Planning and Engineering before building review
The building page asks applicants to check with Planning and Engineering before a building application. It describes electronic submission of plan sets with the permit worksheet and supporting documents; reconcile these instructions with the design packet’s copy requirements.

Local planning journey
Which planning question to resolve first here, and why it shapes the brief. Each answer comes from the cited City page or stays a question for staff.
Question 1
Which design review applies to the scope?
The Planning Permits page (read October 13, 2026) says the Design Review Packet applies to new construction, exterior modifications, changes in site features and landscape review.
source: Claremont · Planning permitsQuestion 2
Is the existing structure on the City's historic Register?
The Register of Structures of Historical & Architectural Merit is the City's official list; the packet asks about it. This matters only where the property is listed or in a historic context.

Is it a Residential Rural parcel?
The packet's Rural Claremont site analysis applies to those parcels, not citywide.

Finding the current official checklist
Use the Design Review Packet from the Planning Permits page, and coordinate Engineering before building plan check.
Owner evidence to gather first
- Register status of the existing structure
- Zone (Residential Rural or other)
- Landscape and site feature plan

Local issues and the budget lines they touch
| Local issue | Budget line it affects |
|---|---|
| Landscape review | Landscape design in the design review set |
| Rural site analysis | Site study where the zone requires it |
No dollar amounts or local premiums are implied.
Hypothetical: a buyer north of Foothill Boulevard confirms the lot is Residential Rural but not on the Register, so the design budget includes the rural site analysis and skips historic assessment.
What shapes the budget here
- Design-review presentation and exterior details kept separate from construction drawings
- Historic or rural site investigation if the parcel’s designation requires it
- Landscape, engineering and revised drawing scope explicitly included or excluded in proposals
These items affect cost; none is a price. See how to build a realistic budget: Custom home budget guide
Parcel questions to answer first
- Is the existing structure register-listed, and what does that mean for replacement rather than retention?
- Is this a Residential Rural parcel, or does a different zone checklist apply?
- Who will reconcile the design approval, landscape plan and construction set after comments?
Gather before a first conversation
- Address or APN and recent site photos
- Survey, title report and prior permits if available
- Architect drawings, or a written list of rooms and priorities
- Target timing and how you plan to finance construction
