Moss Beach CA Real Estate & Homes For Sale
Moss Beach is an unincorporated coastal community in San Mateo County, so county planning and Midcoast rules apply rather than Half Moon Bay’s.

Moss Beach homes: assess the residence and its coastal site
A Moss Beach home search should begin with the exact residential parcel and its practical setting. The community is unincorporated, and the investigation should distinguish the existing home from any future building idea. A broad coastal description does not settle exposure, access or development requirements.

Investigate the systems you inherit
Walk the outside of the residence and identify maintenance access, drainage and useful outdoor areas. Request available records for significant exterior work and compare those records with current inspection findings. Replacement history and current condition provide different information.
Confirm the utility arrangements serving the parcel. If an addition or new unit is part of your plan, describe it precisely when seeking agency guidance. Existing service should not be treated as a promise of capacity for a different future use.
Buying in Moss Beach
Use the county planning and permit resource to route records questions. The county workbook brings together the existing-property file and current Midcoast project check without making an entitlement claim for an individual parcel.
Compare homes by actual usable layout, outdoor function and condition. Montara and El Granada provide nearby community alternatives. Keep an incorporated Half Moon Bay candidate in its own municipal record track.
Selling a Moss Beach home
Prepare a precise improvement chronology and the available service or site documents. Show the home’s existing outdoor utility rather than relying on a general claim about coastal lifestyle. If marketing a proposed change, state its real status and avoid guaranteeing timing or approval.
The San Mateo County seller service connects the property evidence with preparation and a relevant pricing comparison. The buyer service supports a linked purchase with a different site or maintenance budget.

Where Moss Beach is and who governs it
Moss Beach is an unincorporated community on the San Mateo County Midcoast, between Montara to the north and El Granada and Princeton to the south. It has no city government. San Mateo County Planning and Building issues planning and building permits, and the Board of Supervisors governs. Half Moon Bay is a separate city with its own rules.
Moss Beach is inside the County’s Coastal Zone and the urban Midcoast. The Local Coastal Program (LCP) requires a Coastal Development Permit or an exemption for all development, and County zoning, building and health codes apply on top of it. Our unincorporated San Mateo County guide covers the basics.
Water, sewer and utilities in Moss Beach
San Mateo LAFCo’s district table lists the same providers for Moss Beach as for Montara:
- Water, sewer and garbage: the Montara Water and Sanitary District (MWSD), which serves Montara, Moss Beach and adjacent areas north of El Granada. Confirm the current franchise hauler and account with MWSD.
- Fire: the Coastside Fire Protection District.
- Lighting and other services: the Montara Highway Lighting District, County Service Areas No. 10 and No. 12, the Midpeninsula Regional Open Space District and SamTrans.
MWSD’s FAQ says its water comes from nine active wells and treatment facilities, with 1.44 million gallons of tank storage. The district resumed new connections in 2013 after a long moratorium. It serves about 1,658 active water connections and about 1,943 sewer connections, plus 221 connections on the Pillar Ridge water system and 151 private fire-sprinkler connections. Sewage is pumped through an intertie pipeline to the treatment plant in Half Moon Bay.
A few Moss Beach parcels have a private well or septic system. These fall under San Mateo County Environmental Health’s onsite wastewater and well programs. Ask the seller which systems serve the house, and get the records.
Homes, lots and land use in Moss Beach
Moss Beach homes sit on bluff-top, inland and hillside streets under County zoning and the LCP. For a new unit, the County’s June 22,2026 notice reports a 40-unit annual cap including ADUs. It says new-unit building applications cannot be accepted until January 1,2028 unless an LCP amendment provides relief; active applications continue to be processed. Planning applications remain open, with approved cases placed on a waitlist. The County encourages a Formal CDX for ADUs/JADUs normally requiring no planning permit. Amendment LCP-2-SMC-26-0048-1 was scheduled for November 4,2026. Check subsequent County and Coastal Commission actions and obtain written status for the actual application before relying on a timeline.
If you are planning an ADU, also check the LCP’s Moss Beach–Montara ADU special parking map.
Shoreline parcels need extra review. The County’s James V. Fitzgerald Marine Reserve at 200 Nevada Avenue protects the rocky intertidal zone and lies within the Montara State Marine Reserve, a state Marine Protected Area. Bluff-top work and drainage near the shoreline usually get careful coastal review, so ask Planning staff before you count on an addition.
Hazards and insurance to check
- Tsunami: Check bluff-base and low-lying parcels on the California Geological Survey’s tsunami hazard area maps.
- Earthquake, landslide and bluff erosion: Look up the parcel in EQ Zapp, and read the Natural Hazard Disclosure report. For bluff-top or sloping lots, a geotechnical report is the right tool.
- Wildfire: Check the State Fire Marshal’s Fire Hazard Severity Zone maps.
- Flood: Check FEMA’s Flood Map Service Center. Our flood insurance guide explains lender requirements.
Getting around from Moss Beach
State Route 1 connects Moss Beach north to Montara and Pacifica and south to El Granada and Half Moon Bay. SamTrans Route 117 serves Moss Beach between the Linda Mar Park & Ride and Half Moon Bay. Ride Plus offers on-demand shared trips within Moss Beach, Montara, El Granada and Half Moon Bay from 7 a.m. to 5 p.m. daily, according to SamTrans’ Coastside services page.
Local rules buyers and owners should know
- Midcoast cap: Any new unit or ADU depends on the cap and waitlist.
- Coastal permits: Exterior development needs a Coastal Development Permit or a documented exemption.
- Transfer tax: The County’s documentary transfer tax is generally 55 cents per $500 or fraction of taxable value, subject to statutory thresholds, deductions and exemptions. There is no city transfer tax in unincorporated Moss Beach.
- Tax bill charges: Look for district and County Service Area charges. See San Mateo County property tax and our Coastside land guide.
Luxury homes and estates in Moss Beach
In Moss Beach, high-end property usually means a bluff-top or ocean-view home, or a larger inland lot. All of it is in the County’s Coastal Zone and the urban Midcoast. Bluff-top and shoreline parcels get the closest coastal review, especially near the Fitzgerald Marine Reserve and the Montara State Marine Reserve. Any added unit depends on the Midcoast cap and waitlist, so price a property for the house and lot as they stand today.
Due diligence for a high-value purchase: For a bluff-top home, get a geotechnical report on bluff retreat and drainage, and ask County Planning what limits apply to additions or shoreline protection. Check the tsunami map, confirm the Montara Water and Sanitary District connection, and review the County permit history. Get insurance quotes early. Our FAIR Plan guide and our guide to insuring a high-value home cover the options.
Ask Diamond Real Estate Group which permitted private-marketing options fit your property, goals and the applicable MLS rules. Availability of any particular listing is not guaranteed. Related: San Mateo County luxury homes.
Moss Beach real estate: questions people ask
Is Moss Beach part of Half Moon Bay?
No. Moss Beach is unincorporated San Mateo County, so the County issues permits and the Local Coastal Program applies. Half Moon Bay is a separate city to the south. Water, sewer and garbage in Moss Beach come from the Montara Water and Sanitary District, not Half Moon Bay.
Where does Moss Beach’s water come from?
The Montara Water and Sanitary District supplies it from nine active wells and a surface water treatment plant, stored in seven tanks. The district has served new connections again since 2013, when it lifted its moratorium. It works with County Planning on connections in urban zones.
Can I add an ADU to a Moss Beach home?
The County’s June 2026 notice includes ADUs in the cap and describes a Formal CDX waitlist route. Confirm subsequent amendments, the actual application status and the applicable parking map with Planning.
What should I check on a bluff-top Moss Beach home?
Get a geotechnical report on bluff stability and drainage. Check the tsunami map and EQ Zapp, and ask County Planning about coastal permit limits on additions or seawalls. Ask the seller for permits on past exterior and drainage work.
