Build a residence file and an infrastructure file
The residence file covers layout, condition and significant alterations. The infrastructure file covers water, wastewater, legal access and any shared maintenance agreements. Keeping them separate prevents a successful interior tour from leaving the supporting systems unexplored.
Walk the route a contractor or maintenance vehicle would use. Identify slopes, turning space and access to the exterior. Locate useful outdoor ground rather than assuming every wooded acre serves the purpose you have in mind.
Buying in La Honda
Use county planning records for the relevant improvement questions. For a property using onsite wastewater, the county health program provides the official service reference; confirm the actual system rather than assuming every address is identical.
The county property workbook organizes the questions that need provider, title or specialist answers. Obtain address-specific insurance information early enough to affect the decision. Compare Loma Mar and Woodside by the systems and access each actual property provides.
Selling a La Honda home
Provide the available infrastructure and improvement history, with shared obligations explained. Show the approach and useful outdoor areas clearly. Describe existing structures by supported use and keep future activities or expansion ideas distinct.
San Mateo County seller representation connects that file with targeted preparation and pricing; buyer representation supports a coordinated next purchase.

Luxury homes and estates in La Honda
For a La Honda wooded or ridge parcel with a home, outbuildings or private drive, review the land and the systems serving it together. What a parcel can hold is set by San Mateo County, not a city. Look up its district with the County’s zoning lookup and read the rules in the County’s zoning regulations (Title 8) before you pay for a second residence, guest house or barn that a listing describes as possible.
For a larger estate, the due diligence that matters most:
- Insurance first. Ask insurers to assess the specific property’s wildfire exposure, access, water and construction. Start quotes before you write the offer, and read our guides to the California FAIR Plan and insuring a high-value home. Ask what hardening, defensible space and water storage the insurer will credit.
- Every structure on the permit record. Guest cottages, studios and decks can predate any permit. Match each one to a County permit, and match each bathroom to the septic design on file with Environmental Health.
- Water you can rely on. A large landscape or a second home needs a documented supply. Get the well yield test or shared-system agreement in writing. Our La Honda rural water and wastewater page lists the records.
- Access and boundaries. Confirm recorded rights over every private road segment, and who pays for upkeep. See La Honda private roads and site access.
- Agricultural contracts. Larger ranch parcels may carry a Williamson Act contract, which restricts use and changes the tax basis. Ask the seller and the County.
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: coming-soon listing · San Mateo County luxury homes.

Where La Honda is and who governs it
La Honda is an unincorporated community in the Santa Cruz Mountains of San Mateo County, along State Route 84 between Woodside and the coast at San Gregorio. There is no city government. The San Mateo County Planning and Building Department handles zoning, planning permits and building permits, and the Board of Supervisors makes land-use decisions.
San Mateo County’s Local Coastal Program applies to unincorporated communities within the county’s Coastal Zone. La Honda is inland, but some parcels to the west toward San Gregorio may be inside the Coastal Zone. If you plan new construction or a significant change, ask planning staff whether a coastal development permit applies to the parcel. Our unincorporated San Mateo County page explains county-versus-city rules.
Water, sewer and utilities in La Honda
- Septic: La Honda homes generally use onsite wastewater (septic) systems. San Mateo County Environmental Health runs the county’s land use review and onsite wastewater programs, including onsite wastewater treatment systems, wells, and Environmental Health review of planning and building applications. Additions that add bedrooms usually need Environmental Health sign-off on septic capacity.
- Water: Supply varies by parcel. It may be a small water system or mutual company, a private well or a spring. Ask for the water source documents, any shared-system bylaws or agreements, recent bacteriological tests and, for wells, a flow test. Environmental Health handles well permits.
- Roads: Many homes are reached by private or shared roads. Road maintenance agreements are as important as utility records. Ask for them, and for any recorded easements, during escrow.
Homes, lots and land use in La Honda
La Honda’s housing is mostly cabins and houses on wooded, sloping lots, along with some larger rural parcels. County zoning and the General Plan set what each parcel allows. For a steep lot, review access, wastewater capacity and slope stability alongside zoning and the applicable state housing pathway. Ask the county for permit history on decks, additions and accessory structures before you treat them as legal space.
Public open space surrounds much of the community. Midpeninsula Regional Open Space District’s La Honda Creek Open Space Preserve now covers more than 6,400 acres. It is reached from Highway 84, with a 23-space lot off Sears Ranch Road and permit-only parking on Allen Road.
Hazards and insurance to check
- Wildfire: Evaluate wildfire exposure, access and insurance early. Look up the parcel in the State Fire Marshal’s Fire Hazard Severity Zone viewer. Mountain parcels like these are often in the State Responsibility Area, where maps took effect April 1, 2024. Get homeowners insurance quotes at the start of escrow, not the end.
- Earthquake fault zones: The California Geological Survey released a revised official Earthquake Zones of Required Investigation map for the San Gregorio and La Honda quadrangles on November 20, 2025. It shows Alquist-Priolo fault zones for the San Gregorio Fault Zone. Seismic hazard (liquefaction and landslide) zones have not been prepared for these quadrangles, so a landslide question needs a site-specific geotechnical review. Check the parcel in EQ Zapp.
- Flood: Creekside parcels along La Honda Creek should be checked on FEMA’s Flood Map Service Center.
Getting around from La Honda
State Route 84 is the main road, east over the ridge to Woodside and the Peninsula, and west to San Gregorio and Highway 1. Nearby communities include Loma Mar, Pescadero and Half Moon Bay. Mountain driving times vary with weather and road work, so drive the route at the hours you would actually commute.
Local rules buyers and owners should know
- Transfer tax: San Mateo County’s documentary transfer tax is 55 cents per $500 or fraction of taxable value, subject to the statutory threshold, deductions and exemptions. La Honda is unincorporated, so no city transfer tax applies.
- Coastal permits: Parcels inside the Coastal Zone follow the county’s Local Coastal Program and may need a coastal development permit for new development.
- Property tax: Review the actual bill for fire, school and other special assessments. See our San Mateo County property tax guide.
La Honda real estate: questions people ask
Is La Honda a city?
No. La Honda is an unincorporated community in San Mateo County, so county planning, building and Environmental Health rules apply. Parcels to the west toward the coast may also fall inside the county’s Coastal Zone, where the Local Coastal Program adds permit requirements for new development.
Do La Honda homes have septic systems?
Generally yes. San Mateo County Environmental Health oversees onsite wastewater systems and wells and reviews planning and building applications. Before buying, get the septic permit history and a recent inspection and pumping report. Confirm capacity if you plan to add bedrooms or a second unit.
Is La Honda near an earthquake fault?
The state’s November 2025 revised map for the San Gregorio and La Honda quadrangles shows Alquist-Priolo zones for the San Gregorio Fault Zone. Mapped-zone disclosures and investigation duties depend on the applicable law, transaction and project. New construction there may need a fault investigation. Check the parcel in EQ Zapp.
How much is the transfer tax on a La Honda sale?
San Mateo County charges documentary transfer tax at 55 cents per $500 of value, or $1.10 per $1,000. Because La Honda is unincorporated, no additional city conveyance tax applies. Who pays is negotiable. Confirm the figures with your escrow officer.
