Start selling your San Mateo County land with its parcel number and the records you already have. Check the full zoning label before describing what a buyer could build. Then gather maps, explain access and compare offers by the money you would keep.
Tell us about your land. There’s no obligation to accept an offer.
Start with what you know. These steps will help you get ready and choose the way to sell that fits you.
Find the assessor parcel number, or APN, on a tax bill. Keep it with the deed, owner names and any survey you have. For several tracts, make one row for each APN. Note which parcels you want to sell together.
The County Clerk-Recorder page links to its online grantor-grantee index. This is a record index for the people or parties who transfer and receive property. The office records deeds, mortgages, liens and releases, among other documents.
Save the document number and date for papers that may affect your land. Ask the office about copies when you need the full document. An index entry alone does not explain every term or show that an old debt has been paid. Share the papers with the team handling your sale.
For land outside city limits, start with the county’s zoning lookup guide. It calls for a nine-digit APN and says an address search may not find the parcel. In the map viewer, turn on Unincorporated SMC Zoning. Enter the APN without spaces or dashes.
A parcel can have several zoning labels. The guide explains that each part points to rules that may apply. For example, CD marks the Coastal Zone, while DR points to design review. Keep the full label rather than copying only the first part.
Ask Planning how those labels affect the use a buyer has in mind. For land inside a city, start with that city’s planning office. Keep answers and dates with your records. Do not turn a map label into a promise that a home or other project is approved.
The county’s Surveying and Map Checking page links to recorded survey and subdivision maps. It also lists an index of maps in county archives that were not filed for recording. An old deed may refer to one of these records.
The same page explains that recorded rights to use land, called easements, may appear on maps, deeds or other papers. It warns that a map or the latest deed may not show every easement. Keep older records that could help explain a shared drive or utility route.
Give a buyer clear directions and tell them about gates or shared roads. If the papers and the route on the ground do not match, flag the question early. Ask the closing team or a surveyor which records need a closer look. Do not guess from a line on a screen.
Write directions from a public road. Note gates, shared drives and who should approve a visit. If reaching the land means crossing another tract, share any written access agreement with the closing team.
List what you know about water, power and septic. Save well reports, service letters and permit records you have. Say what is unknown. Equipment on the land does not by itself answer whether it works or whether a new use can be served.
For land in use by someone else, share leases or other written agreements. Explain what the buyer needs to check about that use before choosing a closing date.
Start with land that might appeal to the same buyer. Compare access, slope, usable space and services before comparing acres. A small lot with utilities is a weak match for a large tract without services, even if both are nearby.
Keep confirmed sale prices separate from active asking prices. Save each useful sale’s date, parcel identity and main differences. Do not turn an unverified listing into a completed sale or use a tax value as your only price guide.
If useful sales are scarce, ask a local land agent or appraiser to explain a reasonable range. Our California land seller guide has more ways to prepare.
A land agent can help market the property and handle buyer questions. Ask about fees, the listing term and how visits will work. Selling it yourself gives you more of that work, including calls and offer review.
A direct offer gives you another option to compare. Ask what the buyer still needs to check, which costs you pay and when either side can cancel. Do not choose from the headline price alone.
Reelvest buys land directly from owners. Tell us about your San Mateo County land if you want us to review it for an offer. You can compare any offer with your other choices before deciding.
Ask the closing team to list the price, your costs, loan payoffs and any taxes to be paid. That estimate helps show the money you would keep. Ask which figures are still subject to change.
Mention shared owners, an estate, a name change or an old loan early. Keep a list of needed papers and who will provide them. A target date is more useful when you know what must happen first.
Use our document checklist to organize what you have. If you want to sell several tracts together, our land portfolio page explains how to start with a parcel list.
A San Mateo County parcel can have more than one zoning district. Keep every part of the label and ask Planning how the rules apply to the proposed use.
The county guide calls for the nine-digit APN without spaces or dashes. Find it on a tax bill. The guide warns that an address search may not identify the parcel.
Start with the county Surveying and Map Checking page. It links to recorded survey and subdivision maps and a separate index of some older unrecorded maps.
Yes. Share the location and what you know, then list the records or answers you still need. We can review the details and let you know if we can make an offer.
