Planning a custom home in Newport Beach
Much of Newport Beach is in the coastal zone, where the City requires a Coastal Development Permit for development unless it is exempt or excluded. Public case records show demolish-and-rebuild homes going through that path.
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
Confirm whether a CDP is required

Know who decides
The Zoning Administrator usually reviews CDPs; other discretionary approvals move it to that body, and tidelands or deferred-certification areas go to the Coastal Commission.

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
Is the project in the coastal zone, and is it exempt, excluded or eligible for a waiver?
The City's CDP handout (revised October 2023) requires a CDP for all development in the coastal zone unless exempted or excluded. Chapter 21.52 of the LCP Implementation Plan lists exemptions, categorical exclusions and a de minimis waiver (section list read October 13, 2026).

Who decides the CDP?
The handout explains review authority; ask which decision-maker and any appeal path apply to your parcel.

What did comparable demolish-and-rebuild cases include?
Public case records show what similar projects submitted; they are examples, not requirements for yours.

Finding the current official checklist
Use the City's Coastal Development Permit handout and the LCP Implementation Plan chapters; ask Planning for the current application checklist, since the handout carries an October 2023 revision.
Owner evidence to gather first
- Coastal zone status of the parcel from the City
- Existing house records for the demolition
- Comparable public case records you reviewed
Newport Beach coastal review outcomes to ask about
| Outcome named in Chapter 21.52 | What to ask Planning |
|---|---|
| Exempt from coastal permit | Which exemption, and whether it applies to a full replacement |
| Categorical exclusion | Whether the parcel lies in an excluded area |
| De minimis waiver | Whether the project could qualify |
| Coastal Development Permit | Decision-maker, hearing and appeal path |

Local issues and the budget lines they touch
| Local issue | Budget line it affects |
|---|---|
| CDP path | Application preparation and review time |
| Waterfront or bluff conditions, where present | Specialist reports the City requests |
No dollar amounts or local premiums are implied.
Hypothetical: an owner on the Balboa Peninsula assumes a replacement home is exempt because the footprint is unchanged. Reading Chapter 21.52's list first, they ask Planning which outcome applies before scheduling the design.
What shapes the budget here
- Coastal permit preparation and hearing
- Water quality and drainage plans
- Distance: travel, supervision and deliveries from Los Angeles
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 lot in the coastal zone, and is the project exempt or excluded?
- Is the parcel on tidelands or in a deferred-certification area?
- Does the project need any other discretionary approval?
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
