Half Moon Bay Real Estate Agent

Nearly every Half Moon Bay project needs a Coastal Development Permit. Representation that reads the coastal rules before the price.

Lisa M. Lum is a Half Moon Bay real estate agent with Coldwell Banker Realty, working from the office at 1706 El Camino Real in Menlo Park. Half Moon Bay sits on the San Mateo Coast, 28 miles south of San Francisco, along Highway 1 and Highway 92.

It’s the principal city on the Coastside. Miramar, Princeton-by-the-Sea, El Granada, Moss Beach and Montara are unincorporated, and San Mateo County governs them.

Pillar Point Harbor in Princeton is a working fishing marina. The shoreline includes Francis State Beach and miles of coastal trail along the Half Moon Bay State Beaches.

Inside city limits, Ocean Colony Estates surrounds the Half Moon Bay Golf Links, and The Highlands sits east of Highway 1.

The whole city lies within the California Coastal Zone. That fact, along with flood maps and bluff erosion, shapes what you can build and what you must disclose.

Lisa walks you through those rules for a specific property before you commit to a number.

Selling your Half Moon Bay home

A Half Moon Bay sale is priced by its place on the coast. A golf-frontage home in Ocean Colony Estates and a mid-century home in The Highlands answer to different buyers.

Lisa manages the marketing, showings and negotiations.

Disclosure is where coastal sales get detailed. If your parcel is blufftop, beachfront or erosion-prone, disclose prior Coastal Development Permit conditions, public access easements and any shoreline-protection policy affecting it.

If your home is in an HOA such as Ocean Colony Estates, gather the governing documents early.

If your home is on private septic, confirm with San Mateo County Environmental Health what inspection applies to your sale, and schedule it ahead of launch.

Through her Home Refresh program, Lisa manages the vendors for repairs, paint, staging and curb appeal, and you approve every estimate before work begins.

Home Refresh also covers a pre-listing inspection and a disclosure package, ready before the first showing.

Total documentary transfer tax is $1.10 per $1,000, split between city and county. How it affects your proceeds is a question for your tax advisor.

When offers arrive, Lisa reviews each one with you on price, terms, contingencies and the buyer’s financing.

Buying a home in Half Moon Bay

Start with the permit layer. Because the entire city is in the Coastal Zone, nearly all development requires a Coastal Development Permit under Municipal Code Chapter 18.20, on top of standard zoning review.

Single-family zoning falls under Chapter 18.06, where R-1 is the predominant zone. If you plan to remodel or add on, talk with the Community Development Department before you sign.

Next, read the hazard disclosures. They can include FEMA Special Flood Hazard Areas, coastal erosion and bluff retreat zones, tsunami inundation zones, the Alquist-Priolo Earthquake Fault Zone and Very High Fire Hazard Severity Zones.

On blufftop and beachfront parcels, look for public access easements and prior permit conditions.

Trees count too. The Heritage Tree Ordinance covers any tree with a trunk at least 12 inches in diameter, on public or private property, and removal requires a permit.

Know which side of the city line you’re on. In the unincorporated communities, the county governs, and many homes use private septic systems regulated by San Mateo County Environmental Health. Ask the county what inspection applies before you write an offer.

Cabrillo Unified School District serves the city and the surrounding Coastside. Elementary schools are assigned by residence, and students converge at Cunha Intermediate and Half Moon Bay High School. Confirm the assignment for the exact address with the district before you write an offer.
