Salt air, ocean views and crisp evenings are why you love Carmel Highlands. They also test every deck board, bolt and cushion you own. If you want an outdoor space that looks good year after year, you need materials and planning that stand up to wind, fog and salt. In this guide, you’ll learn what lasts, what needs permits, which plants actually thrive and how to keep your space safe and low‑maintenance. Let’s dive in.
Climate realities to plan for
Carmel Highlands has a cool, maritime Mediterranean climate with frequent fog, mild summers and most rain in winter. Local NOAA climate summaries reflect that pattern, so design for wind and chill rather than high heat.
Salt spray and onshore winds accelerate corrosion and fade fabrics. Expect more frequent upkeep than inland homes and choose coastal-grade materials from the start.
Build with coastal‑grade materials
Metals and fasteners
Use 316 stainless steel or hot‑dip galvanized connectors and fasteners where specified. Detail steel with protective coatings and allow rain to rinse surfaces so salt does not concentrate. For structural choices and corrosion control, see FEMA’s coastal construction guidance in FEMA P‑499.
Decks and finishes
Choose rot‑resistant or engineered decking such as thermally modified wood, Ipe or capped composites rated for coastal exposure. Promote airflow and drainage to keep surfaces dry, and use marine‑grade hardware. Pick UV‑ and mildew‑resistant outdoor fabrics and store cushions when storms roll in.
Hardscape and drainage
On sloped lots, design subdrainage and erosion control that do not concentrate runoff at the bluff edge. Avoid heavy loads near bluff tops without geotechnical clearance. The California Coastal Commission’s Sea Level Rise guidance outlines bluff setback and shoreline armoring limits that can affect terraces and permanent structures.
Permits and coastal rules
Carmel Highlands sits in unincorporated Monterey County’s coastal zone. Many exterior projects require approvals. Decks, large patio covers, grading, and built outdoor fireplaces often need a County administrative approval or a Coastal Development Permit, and some can be appealed to the Coastal Commission. Review the County’s Design Approval Guidelines Matrix early.
For fire features and built‑in grills, confirm requirements with Monterey County Planning and your local fire district. Also plan for defensible‑space clearances around any combustible elements; CAL FIRE’s defensible space guidance is the standard.
If your site is near a bluff, verify setbacks and coastal hazards before investing in permanent structures. The Coastal Commission’s Sea Level Rise guidance is a helpful starting point.
Water‑wise landscaping that thrives
Plant palette for the coast
On exposed coastal sites, favor low, salt‑tolerant species such as seaside daisy (Erigeron glaucus), coastal buckwheats (Eriogonum spp.), and low manzanitas for back slopes. Coordinate plant choices with local native‑plant resources like the CNPS Monterey Bay chapter’s guides to resilient natives, including local salvia recommendations. Some coastal species are protected; do not disturb them without guidance.
Smart irrigation and rebates
Reduce water use and costs with drip irrigation, smart controllers and soil‑moisture sensors. The Monterey Peninsula Water Management District offers rebates for turf conversion, smart controllers, soil sensors and cisterns. Check current programs on the MPWMD rebate page.
Erosion and bluff plantings
Use native groundcovers and shrubs to help stabilize soils where allowed, and avoid invasive ice plant. For restoration‑style approaches and species ideas, see local dune and bluff work such as CSUMB’s coastal dune restoration projects.
Wildfire and safety essentials
California law requires defensible space around structures, typically up to 100 feet or to the property line. Create a lean, clean zone near the house, keep furniture and fire features clear of walls, and thin vegetation farther out. Start with CAL FIRE’s defensible space guidance and consult the Carmel Highlands Fire Protection District for local programs and inspections on their Firewise information page.
Routine cleaning reduces both fire risk and salt damage. Keep roofs, gutters, decks and drains clear of debris, especially during fall and winter.
Septic and utilities check
Many Carmel Highlands properties use onsite wastewater systems. Adding bedrooms, expanding hardscape or changing drainage can trigger reviews. Confirm capacity and permits early with Monterey County Environmental Health’s OWTS program to avoid delays.
A simple project roadmap
- Confirm site constraints: bluff setbacks, slope stability and protected habitats. The Coastal Commission’s Sea Level Rise guidance explains key coastal hazards to consider.
- Check water‑saving rebates to refine scope and budget on the MPWMD rebate page.
- Review permit needs for decks, covers and fire features with the County’s Design Approval Guidelines Matrix and your local fire district.
- If septic or footprint changes are likely, schedule an early site evaluation through the County’s OWTS program.
- Specify coastal‑grade materials using FEMA’s P‑499 guidance, and plan for periodic inspections and maintenance.
Long‑term maintenance habits
- Rinse salt from metals and walls after storms. Re‑seal or repaint exposed metal on a set schedule.
- Inspect and re‑treat wood and composite finishes annually or per manufacturer.
- Service gas lines, grills and sealed electrical enclosures on a regular cycle to spot corrosion early.
- Keep roofs, gutters and decks clear of needles and leaves to reduce fire risk and moisture retention.
- Maintain septic pump‑outs and inspections per county guidance.

FAQs
What materials last longest for Carmel Highlands decks?
- 316 stainless fasteners with thermally modified wood, Ipe or capped composites perform well in salt and fog when detailed for drainage and maintained per FEMA P‑499.
Do I need a permit for an outdoor fireplace in the Carmel Highlands coastal zone?
- Many built outdoor fireplaces and large covers require County administrative approval or a Coastal Development Permit; always verify against the County’s Design Approval Guidelines Matrix and check defensible‑space clearances with your fire district.
Which plants handle salt and wind best near the ocean in Carmel Highlands?
- Low, salt‑tolerant natives such as seaside daisy, coastal buckwheats and low manzanitas are strong candidates; consult local CNPS resources for site‑specific lists and to avoid disturbing protected species.
How do Monterey Peninsula water rebates work for irrigation upgrades?
- MPWMD offers rebates for turf conversion, smart controllers, soil sensors and cisterns; eligibility and amounts vary by project, so review current details on the MPWMD rebate page.
What should Carmel Highlands homeowners know about defensible space around patios?
- Maintain a clear zone near structures, keep combustible furniture and features away from walls, and thin vegetation outward per CAL FIRE’s defensible space guidance; local districts may add inspections or rules.
