Thinking about a Summerland bluff-top home or planning an upgrade with an ocean view? Before you fall in love with a deck design or addition, you need to understand coastal setbacks. These rules shape what you can build, where you can place it, and how long approvals take. In this guide, you’ll learn how setbacks work in Summerland, who regulates them, what projects trigger permits, and the smart steps to protect your plans and your investment. Let’s dive in.
What a coastal setback is
A coastal setback is the required horizontal distance between a coastal feature and your structure. The feature could be the top of a bluff, the mean high tide line, or a shoreline structure. Setbacks exist to reduce risk from bluff or shoreline erosion, protect coastal resources, and avoid the need for future shoreline armoring.
Setbacks are not one-size-fits-all. They are site-specific and based on current conditions plus projected future erosion and sea level rise over a planning horizon. Agencies often use 50- to 100-year horizons to set distances that keep structures safe for their expected life.
What counts as “development”
In California’s coastal zone, “development” is defined broadly. It usually includes new buildings, additions, decks, stairways, grading, seawalls, and sometimes utilities and landscaping. That means many projects that seem minor can trigger setback review and permit requirements.
Who regulates projects in Summerland
Summerland is in unincorporated Santa Barbara County within the coastal zone. Two layers of oversight apply:
- Santa Barbara County implements the Local Coastal Program and issues most Coastal Development Permits.
- The state’s California Coastal Commission sets statewide policies and may review or hear appeals for certain projects.
In practice, you must meet County requirements, and some projects are subject to appeal or direct review by the Coastal Commission.
Permits you will likely need
- Coastal Development Permit (CDP). This is the main coastal permit. Many projects are discretionary and require technical review before approval.
- Building and grading permits. These are issued after coastal approval and must follow geotechnical recommendations and erosion-control measures.
- Limited exemptions or emergency repairs may apply in narrow cases, but do not assume your project is exempt without County confirmation.
When your project triggers setback review
Common triggers include:
- New habitable additions or accessory structures.
- New decks, balconies, or bluff stairways that change footprint or access.
- Grading, retaining walls, or drainage changes near the bluff top.
- Structural repairs that affect foundations or alter massing.
Like-for-like repairs that do not change footprint, structure, or drainage may be eligible for ministerial approval, but this is case-by-case. Always verify with the County before you begin.
Geotechnical studies and planning horizons
Most bluff-top or near-bluff projects require a site-specific geotechnical or geologic hazards report. These reports typically include:
- Mapping of the bluff edge, slopes, and subsurface conditions.
- Historic bluff retreat or erosion rates if available.
- Current stability, groundwater conditions, and potential failure planes.
- Erosion and retreat projections for a 50- to 100-year planning horizon that consider sea level rise.
- Recommendations for setbacks, foundations, drainage, erosion control, and monitoring.
The County uses this analysis to set allowable footprints and permit conditions. Many approvals include monitoring or future mitigation requirements.
Timing, cost, and design impacts
- Time. Coastal review can add weeks to many months for smaller projects and several months to over a year for larger or controversial ones, especially if appeals occur.
- Cost. Plan for permit fees and technical studies. Geotechnical and coastal engineering reports often cost several thousand dollars, depending on complexity. Design changes to limit footprint, control drainage, or modify foundations may also be required.
- Design limits. Setbacks reduce buildable area. New shoreline armoring is strongly discouraged and, if proposed, faces strict conditions and a higher risk of denial.
Insurance, loans, and resale
Lenders and insurers increasingly scrutinize coastal hazards. Some insurers may limit coverage for high-risk bluff properties, and lenders may require geotechnical assurances. Sellers must disclose known hazards and any material facts that affect value or habitability. Look for recorded notices or covenants that reference geologic hazards or restrict future development.
Due diligence essentials for buyers
Request these records during escrow:
- Copies of any Coastal Development Permits and recorded conditions.
- Building and grading permits and inspection records.
- Geotechnical and coastal engineering reports, including monitoring updates.
- Any County or Coastal Commission correspondence or enforcement notices.
- Recorded deed restrictions, easements, or Notices of Geological Hazard.
- Seller disclosures related to erosion or bluff hazards.
Consult the right specialists:
- Coastal or land-use attorney familiar with the County’s Local Coastal Program.
- Licensed geotechnical engineer or engineering geologist with coastal bluff experience.
- Coastal engineer if shoreline protection or complex drainage is contemplated.
- Local planning and permitting consultant who knows Summerland procedures.
Ask targeted questions:
- Has the property had a Coastal Development Permit, and what conditions apply?
- Are there geotechnical reports and any monitoring records I can review?
- Have there been enforcement actions, appeals, or denials on this parcel?
- Are there recorded restrictions about bluff erosion or required setbacks?
- Have shoreline protective devices been proposed, approved, or denied here or next door?
Red flags that warrant caution
- No geotechnical report on file for a bluff-top property.
- Recent enforcement actions, appeals, or denials on nearby properties.
- Recorded notices on title referencing erosion hazards or development limits.
- Evidence of active bluff instability in historic photos or aerials.
- Neighboring properties with seawalls or proposed armoring that suggest ongoing erosion issues.
Early steps if you plan improvements
- During escrow, secure a pre-purchase review by a geotechnical engineer, or make it a condition.
- Contact Santa Barbara County Planning and Development early to discuss CDP requirements and timelines.
- Budget for permit review time and technical studies before you finalize designs.
- If proposing a major addition or any shoreline protection, consult a coastal attorney before submitting plans.
Helpful resources
- Review statewide coastal policies and appeals information at the California Coastal Commission.
- Check flood zone data using the FEMA Flood Map Service Center.

Plan with a local advisor
Setbacks are manageable when you verify the rules early, assemble the right team, and plan for site-specific conditions.

FAQs
What is a coastal setback in Summerland?
- It is a required distance between a coastal feature, such as the top of a bluff, and your structure to reduce hazard risk and protect coastal resources over time.
Do decks or stairways near a bluff need permits in Summerland?
- Yes, decks and bluff stairways often qualify as development in the coastal zone and can require a Coastal Development Permit and a setback analysis.
How long does a Coastal Development Permit take in Santa Barbara County?
- Minor projects can take weeks to many months, while larger or contested projects may take several months to over a year, especially if appealed.
Who decides the setback distance for a Summerland bluff-top home?
- Setbacks are based on a site-specific geotechnical analysis and applied by Santa Barbara County under its Local Coastal Program, with potential Coastal Commission review.
What records should a Summerland buyer request during escrow?
- Ask for prior CDPs, building and grading permits, geotechnical reports, any County or Commission correspondence, and recorded title notices about geologic hazards.
