Del Mar's own rules for remodels, rentals and bluffs

Short answer: Del Mar is its own city. It has a certified Local Coastal Program, its own Design Review path, short-term rental permits under Chapter 30.96, and bluff overlay rules that do not match the City of San Diego line for line. Here is the short version of how remodels, rentals and bluff lots work.

If you are used to San Diego’s process, pause before you assume the same steps in Del Mar. I walk clients through Del Mar’s own code so the plan matches the city that will actually review it.

Del Mar runs its own coastal program

The City of Del Mar publishes its certified Local Coastal Program (Land Use Plan plus Implementing Ordinances in portions of Title 30). Planning staff take applications electronically through the Planning Department.

On Coastal Development Permits, the code says: “All properties within the City of Del Mar are located within the Coastal Zone as defined in the California Coastal Act and are subject to the provisions of this Chapter.”

And: “Unless otherwise provided in this Chapter, no development, as defined herein, shall occur unless and until a Coastal Development Permit has been granted in accordance with the provisions of this Chapter.”

In plain words, almost every property in Del Mar is in the coastal zone, and many projects need a Coastal Development Permit along with other city approvals, unless an exemption in Chapter 30.75 applies.

Remodels and design review

Remodels can trigger building permits, design review and a Coastal Development Permit depending on scope and location. Interior-only work is often treated differently from exterior massing, height, footprint or grading changes.

Del Mar also uses a Design Review process aimed at harmonious materials, colors and landscaping for its seaside character. Ask Planning early whether your scope needs Design Review Board action, administrative design review, or both a CDP and other permits.

My general coastal rules guide explains coastal review ideas in plain words; always confirm the Del Mar path for your parcel.

Short-term rentals

Del Mar’s code defines a short-term rental like this: “Short-Term Rental (STR) means, unless otherwise exempt under Section 30.96.025 of this Chapter, the rental of a dwelling unit, or any portion thereof, for dwelling, lodging, or sleeping purposes, for a period of 30 consecutive calendar days or less.”

And: “Any person or entity operating a STR in the City of Del Mar must have a valid STR Permit issued by the City pursuant to Section 30.96.050 of this Chapter.”

In plain words, stays of thirty consecutive calendar days or less generally need a City STR Permit, with exemptions for longer rentals and home exchanges as the chapter spells out. The city also limits how many permits it issues and may use a waitlist when capacity is full. Check the City’s Short-Term Rentals page for the current permit and waitlist status before you buy with a rental plan.

Bluff lots

Del Mar’s Coastal Bluff Overlay Zone states: “The purpose of the Coastal Bluff Overlay Zone is to protect Del Mar's fragile coastal bluffs as a visual resource and avoid the risks to life and property associated with bluff failure and shoreline erosion.”

For setbacks, the code requires new or redeveloped principal and accessory structures to sit at least forty feet back from the coastal bluff edge as the city defines that edge, unless a narrower rule in the chapter applies. Fences and similar light improvements can have a smaller minimum under the same chapter. Grading near that edge is tightly limited.

Applications near bluffs often need topographic mapping and a geotechnical report. My bluff homes guide covers bluff due diligence themes; Del Mar’s overlay is the rulebook for Del Mar parcels.

What I put on your Del Mar checklist

Confirm the parcel’s base zone and any overlays (bluff, beach, lagoon and others).
Ask Planning whether a Coastal Development Permit, Design Review, or both apply to your scope.
If rentals matter, read Chapter 30.96 and the city’s current STR permit status before you count on short stays.
On a bluff lot, budget time for geotechnical work and setback design, not only finishes.

Not legal advice

Codes change, and exemptions are fact-specific. The City of Del Mar Planning Department and the published municipal code are the source of truth.

FAQ

Does every Del Mar property sit in the coastal zone?

Del Mar's Coastal Development Permit chapter says all properties in the city are in the Coastal Zone and are subject to that chapter. Exemptions can still apply to some work under the same chapter.

When do I need a Coastal Development Permit in Del Mar?

Unless an exemption applies, development as defined in Chapter 30.75 needs a Coastal Development Permit before it can occur. Planning staff can tell you whether your scope is exempt, city-issued, or also appealable.

How does Del Mar define a short-term rental?

Under Chapter 30.96, a short-term rental is generally the rental of a dwelling (or part of one) for dwelling, lodging or sleeping for 30 consecutive calendar days or less, unless an exemption applies. A valid City STR Permit is required to operate one.

What should I know about Del Mar bluff lots?

The Coastal Bluff Overlay Zone is meant to protect fragile coastal bluffs and reduce risk from bluff failure and shoreline erosion. New or redeveloped structures generally must sit at least forty feet back from the coastal bluff edge as the city defines it, with extra studies often required.

Are Del Mar's rules the same as San Diego's?

No. Del Mar is its own city with its own municipal code and Local Coastal Program. Do not assume a San Diego permit path applies.

Is this Del Mar rules guide legal advice?

No. It's general information about city process. It's not legal, tax or planning advice. Confirm with Del Mar Planning and your own advisors.
