Coastal Development Permits in Del Mar: Basics

Thinking about a remodel or new build near the beach in Del Mar? Coastal projects come with extra rules that can impact your design, budget, and timeline. You want a clear path forward so you can plan with confidence and avoid surprises. In this guide, you’ll learn when a Coastal Development Permit applies, what the process looks like, how long it can take, and how to scope your project wisely before you hire a full team. Let’s dive in.

What is a Coastal Development Permit

A Coastal Development Permit (CDP) is required for most development within California’s coastal zone to protect coastal resources, access, and scenic views. The process is governed by the Coastal Act and implemented by the California Coastal Commission and local cities with certified Local Coastal Programs. You can review the statewide framework in the Coastal Commission’s overview of permits at the Commission’s official permits page at California Coastal Commission permits.

The Coastal Act in Del Mar

Del Mar administers coastal permitting through its Planning Department and Local Coastal Program. The city handles most CDP decisions for projects that are consistent with its certified program. You can learn about local coastal policies and maps on the City of Del Mar Local Coastal Program page. Some decisions may be appealable to the California Coastal Commission depending on location and issue. Always confirm your parcel’s status with City staff early.

When you need a CDP in Del Mar

If your project changes the exterior, site, or coastal resources, expect to need a CDP. Common triggers include:

• New homes or accessory buildings within the coastal zone.
• Additions that expand the footprint, height, decks, or patios, or that increase intensity of use.
• Demolition and replacement, especially on or near coastal bluffs or the beach.
• Grading, excavation, retaining walls, and drainage or landscaping changes that alter the site.
• Shoreline protection like seawalls, revetments, or bulkheads. See the Commission’s guidance on coastal armoring.
• Work that affects bluff edges, sensitive habitat, wetlands, or public accessways.
• Structures, fences, signage, or utilities within required setbacks or access easements.
• Projects needing variances that may affect public views, access, or coastal resources.

Common exceptions and emergencies

• Interior-only work with no exterior or site changes is less likely to need a CDP, but verify with the City.
• Routine maintenance and minor repairs may be treated differently. Emergency stabilization can be processed on an urgent basis, but you must notify the City right away and follow up with permits.

Site conditions that change the rules

• Bluff setbacks, shoreline proximity, and public access are major factors.
• Presence of sensitive habitat or species can trigger biological review.
• FEMA flood zones and sea-level rise projections often require added analysis. Check flood mapping at the FEMA Flood Map Service Center.

Rule of thumb: if you change the footprint or grade, work near a bluff edge, add habitable area, or propose shoreline protection, plan for a CDP.

How the CDP process works

Every site is unique, but most Del Mar CDP applications move through similar steps. Start here:

Step-by-step timeline

1. Pre-application contact with Del Mar Planning. Staff confirm if a CDP is needed and flag likely studies. See the Del Mar Planning Department.
2. Prepare submittals. You will assemble forms, fees, ownership proof, architectural and site plans, and baseline surveys.
3. Completeness review. Staff check whether your package has the required materials.
4. Technical review. Planning, engineering, building, geotechnical, and environmental reviewers evaluate your plans and studies.
5. CEQA review. Many projects are exempt. If not, the City may prepare a Negative Declaration or Mitigated Negative Declaration, and complex projects can require an Environmental Impact Report. See the statewide overview at OPR’s CEQA page.
6. Public noticing and hearings. Most discretionary projects go to the Planning Commission. Some proceed to City Council.
7. Decision issued. The City approves with conditions, modifies, or denies the permit.
8. Appeal period. Some decisions can be appealed to the California Coastal Commission. Review the basics at Coastal Commission appeals.
9. Permit issuance. Conditions may include monitoring, drainage controls, access requirements, and construction protections.
10. Inspections and compliance. Extensions may be possible if you need more time to start.

Common technical reports

• Geotechnical report with bluff stability and foundation analysis for shoreline or bluff-adjacent sites.
• Coastal hazards and sea-level rise assessment that matches design life and considers future conditions.
• Topographic and boundary survey, grading and erosion control plans, and drainage or hydrology details.
• Biological assessment if native vegetation, nesting birds, wetlands, or other sensitive resources are present.
• Visual analysis for projects near public viewpoints or scenic areas.
• Access plans and construction staging where public access could be affected.

Typical timelines and costs

Actual timing depends on complexity and workload, but these ranges are common:

• Pre-application scheduling: 1 to 4 weeks.
• Completeness review: about 2 to 6 weeks.
• Staff review to decision for straightforward cases: roughly 2 to 4 months after completeness.
• CEQA Negative Declaration or Mitigated Negative Declaration: add 60 to 180 days.
• Appeals to the Coastal Commission or Commission hearings: add 3 to 9 months or more.
• Complex bluff or shoreline projects: plan for 6 to 18 months from pre-application to permit.

Fees and soft costs vary by scope. City application fees depend on permit type. You can review submittal and payment logistics at the City’s Applications, Forms and Fees page. Technical studies for bluff, new home, or demolition-rebuild projects often run into the mid five figures. Large custom homes with extensive studies and potential appeals can exceed $50,000 to $150,000 in soft costs.

What adds time and cost

• Bluff geotechnical uncertainty and required field work.
• Sensitive habitat or species concerns.
• CEQA documents beyond an exemption.
• Public opposition and appeals.
• Projects that rely on new shoreline armoring.

Smart scoping before you hire

Front-load feasibility so you do not design something that is not buildable.

Owner checklist for pre-application

Bring these items to your first meeting with the City:

• Address and APN, vesting deed, and any prior permits or recorded easements.
• Site photos and any available topographic survey.
• Notes on past bluff issues, nearby armoring, flood zone status, and utilities.
• A simple written scope describing what will change, where, and why.

Who to hire first

• Start with a pre-application discussion with Del Mar Planning to confirm requirements.
• Engage a geotechnical engineer early for bluff or near-shore sites. Their input defines safe setbacks and foundations.
• Consider an architect or coastal consultant experienced in Del Mar CDPs to coordinate studies and hearings.
• Add a biologist if native coastal vegetation or nesting birds are present.

Red flags to watch

• New shoreline armoring is the only way to protect proposed development.
• Work would impact sensitive habitat or public access.
• Multiple neighbors are likely to oppose the project.
• The parcel sits in a FEMA V-zone or needs significant grading near a bluff.
• Prior coastal permit conditions limit new development on the site.

Your next steps

• Contact the Del Mar Planning team to discuss your concept and confirm whether a CDP is needed. Use the pre-application checklist to guide that call.
• Ask staff to confirm the Local Coastal Program status for your location and whether a Commission appeal is possible.
• If you are near a bluff or the beach, commission geotechnical reconnaissance before you invest in full design.
• Budget for submittals, technical studies, and CEQA possibilities, and set a timeline that leaves room for public review.
