Planning a custom home in Calabasas
In Calabasas, a lot's visibility from a scenic corridor or a mapped ridgeline can bring extra design standards. Confirm the zoning and those maps before shaping the house.
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
Look up zoning and APN

03
Check for a mapped ridgeline
The same page refers to ridgeline standards in the zoning code (Title 17). Ask whether the parcel contains a mapped ridgeline and which section governs grading and siting.

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 lot within 500 feet of, or visible from, a Scenic Corridor?
The Development Review page (read October 13, 2026) applies the Scenic Corridor Development Guidelines within 500 feet of Mulholland Highway, Las Virgenes Road, Old Topanga Canyon and the Ventura Freeway, and to some visible projects farther away.

Does the property contain a mapped ridgeline?
Properties containing a mapped Significant Ridgeline must comply with the ridgeline section of the Municipal Code. Being near hills is not the same as containing a mapped ridgeline.

Will a public hearing require story poles?
The City's Story Pole Procedures apply to projects with a scheduled public hearing; ask whether yours will have one.

Finding the current official checklist
Start from the Development Review page and the property GIS lookup; confirm each map result with Planning staff.
Owner evidence to gather first
- Distance to the nearest Scenic Corridor
- Ridgeline map check for the parcel
- Views of the site from public roads
Calabasas map checks before design
| Check | If yes |

| Mapped Significant Ridgeline on the property | Ridgeline development standards apply |
| Public hearing scheduled | Story poles under the City's procedures |

Local issues and the budget lines they touch
| Local issue | Budget line it affects |
|---|---|
| Scenic Corridor guidelines | Massing, color and landscape design |
| Story poles | Installation and survey certification |
No dollar amounts or local premiums are implied.
Hypothetical: a lot several hundred feet off Las Virgenes Road looks out of range on paper, but the house would be visible from the road. The owners ask Planning whether the guidelines apply before setting the roof height.
What shapes the budget here
- Visual and design studies for scenic-corridor visibility
- Grading and site planning on ridgeline or sloped lots
- Stormwater and low-impact development measures
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 near or visible from a designated scenic corridor?
- Does the parcel contain a mapped significant ridgeline?
- Does a private homeowners association also review designs? Ask the association directly.
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
