Find your next site in Fullerton, CA.

Off-market deals are properties bought without a public listing, so you find them by screening parcels rather than listings. In Fullerton, the screen starts from the 3,150 lots of 2,000 sq ft or more where zoning allows at least one of six project types: retail, restaurant, office, industrial, multifamily or mixed use. The usual off-market leads are lots the owner is not using to their zoning: 59 of these parcels have no building on them, and 205 have a building covering less than 20% of the lot. Narrow them by permission, lot size and road traffic, then contact the owner of record directly.

Look for parcels with no building on them, which is how the Vacancy filter in ArchiWise defines vacant, rather than relying on county records alone, because records lag behind construction. In Fullerton, 59 parcels where zoning allows development have no building in the Overture Maps buildings, © OpenStreetMap contributors (ODbL), Microsoft, USGS or in the SCAG Regional Land Use (2019 survey, 2024 update). This includes surface parking lots and unbuilt public land, so check the current use on each result. A vacant lot is not necessarily for sale.

Describe the project, then screen every parcel against it: whether zoning permits the use by right or with a conditional use permit, lot size and road traffic, then check the hazard and historic flags on each result. In Fullerton, 3,150 lots of 2,000 sq ft or more allow at least one of the six project types. For redevelopment, look at underutilized lots: 205 have a building footprint under 20% of the lot. The land-use data here records no floor area, so results show building coverage but not built FAR.

Screen for parcels in districts that permit multifamily housing, then look for lots that are empty or barely used. In Fullerton, multifamily is permitted by right in districts covering 1,075 acres of the zoning map. Of the parcels there, 7 have no building on them and 33 have a building covering less than 20% of the lot. Single-family districts are left out even where state law allows lot splits or accessory units. Near the Fullerton train station, the Fullerton Transportation Center Specific Plan regulates development by building type. Its mixed-use building allows retail, services and dining without alcohol on the ground floor and offices or homes above, with bars, live entertainment and some restaurants needing a use permit. Fullerton's Housing Incentive Overlay Zone (HIOZ, FMC 15.17.075) sets its own standards for housing on designated sites; that overlay is not on the zone map used here, so those sites are screened by their base zone only.

Start where zoning permits the use, then rank by road traffic and lot size. In Fullerton, 374 parcels permit retail and front a road carrying at least 20,000 vehicles a day, and 342 permit a restaurant on a lot of 8,000 sq ft or more next to at least 25,000 vehicles a day. Traffic is the 2024 count reported to FHWA (HPMS) for the streets within 75 feet of the lot, added together as the ArchiWise Traffic Volume filter adds them. The screen does not show whether space is available for lease.

Ownership is public record: the Orange County Assessor keeps the owner of record for each parcel, and recorded deeds show transfers. Looking parcels up one at a time is slow when you are screening a whole city. ArchiWise shows the owner of record next to zoning and lot details for each parcel, so a screen can go straight to outreach. Owners are not shown on this public page.

It depends on the parcel's zoning district: its use table says which uses are permitted by right or with a conditional use permit, and its development standards set height, floor area ratio and setbacks. Use permissions are set for 79 of the 84 zone codes on Fullerton's zoning map, from the use tables of the Fullerton Municipal Code, Title 15 (Zoning Ordinance), read against the code text and specific plans where they were checked. The ArchiWise zoning map for Fullerton shows the district of every parcel, and ArchiWise analyzes a specific address for zoning and feasibility.

AI site selection screens every parcel in a market against a project brief, instead of browsing listings one at a time. You describe the project in plain words, such as use, lot size and traffic, and the screen checks each of the 29,664 parcels in Fullerton for zoning permission, lot size, road traffic, building coverage and hazards, then maps the matches. It finds sites that fit; whether a site is for sale, and at what price, still has to be confirmed with the owner.

Parcels and recorded uses come from the SCAG Regional Land Use (2019 survey, 2024 update), building footprints from the Overture Maps buildings, © OpenStreetMap contributors (ODbL), Microsoft, USGS, traffic from FHWA HPMS (2024) and zoning from the Fullerton Municipal Code, Title 15 (Zoning Ordinance). This page previews about 30% of matching parcels; the counts cover every parcel, and the full list is in ArchiWise. Fullerton's parcels and current uses come from SCAG regional land use rather than the county assessor roll, so there is no year built or building floor area, and building outlines come from Overture Maps (OpenStreetMap, Microsoft and USGS). Treat vacancy and building coverage as a starting point and confirm them on site.
