What Lathrop buildings need, and when
Lathrop is a new city with an old core. Of 6,290 units in the 2016 to 2020 survey only 6.9 percent were built in 1970 or earlier and 54.1 percent after 2000, and the unit count went from 5,261 in 2010 to 11,563 in 2025. Around 5 percent need one or more major repairs, typically re-roofing, windows, plumbing, electrical or siding.
The rain falls in a long, mild season and the drainage relies on basins. More than 88 percent of the year's rain comes between November and April, tule fog is common in the mild winters, and on 31 December 2022 the airport station recorded 2.85 inches, a record for the date. Surface runoff reaches detention basins and leaves through pipes and pump stations to the river, ditches and inlets are cleaned each spring and summer, and the 1992 master plan found deficiencies in the historic area.
Every part of the city sits in a 200-year flood hazard area. The San Joaquin River is the primary hazard, with Old River to the west and Paradise Cut to the southwest, and levees are held by three reclamation districts. In January 1997 the east-side levees did not fail but seepage damaged businesses, homes and infrastructure west of Interstate 5.
Summer brings the other extreme, and the ground moves with it. Temperatures often pass 100 degrees, and a July 2024 advisory forecast highs of 100 to 112. Egbert silty clay loam here has moderate to high shrink-swell and is corrosive to uncoated steel, Merritt silty clay loam drains poorly, and liquefaction potential is moderate to high across many parts of the city.
Lathrop areas served
Each Lathrop service page takes these areas separately, because levee district, ground and building age change either side of the freeway.
5th to 7th Street, Lathrop Road to O Street
One of two older areas east of the freeway with scattered homes needing repair, and no curbs, gutters or sidewalks.
Warren Avenue to West Lathrop Road, Harlan Road to Avon Avenue
The second of those areas, where roofs, windows, plumbing, electrical work and siding are the repairs the housing element expects.
Harlan Road, Louise Avenue and Mossdale Road mobile home parks
Five parks from 167 spaces down to two, part of the 381 mobile homes counted in the city in 2022.
Crossroads Industrial Park, I-5 and SR 120
About 528 acres north and east of the interchange, inside the city from incorporation and carrying its own overlay district.
Sharpe depot and Roth Road
A 727-acre federal depot with buildings that make up most of the recorded cultural resources, and solvent contamination on and off site.
South Lathrop: Lathrop Gateway Business Park and TriPoint Logistics Center
168 acres of limited industrial between the rail lines, and a 315-acre specific plan area planned for millions of square feet of warehousing.
Central Lathrop Specific Plan and Stanford Crossing
About 1,521 acres west of the freeway, with a high school, a community center, parks and mapped residential phases.
Mossdale Landing (Mossdale Village)
Entitled for roughly 1,700 homes and 654,000 square feet of commercial beside a river-edge open space corridor.
Mossdale Landing East and South, the I-5 commercial frontage
About 485 homes and 500,000 square feet of commercial to the east, with 140 homes and more service commercial to the south.
River Islands Phase 1 (Stewart Tract, RD 2062)
A community on a leveed island planned for 4,284 homes, with more than 13 miles of levee built or improved since 2005.
River Islands Phase 2 and the Paradise Cut edge
Approved in 2021 for more than 15,000 homes in total, with a setback levee built in 2019 and relief wells behind it.
Southeast Stewart Tract and RD 2107 (Dell'Osso Farms)
913 acres east of the rail embankment, in the district that lacked 100-year protection when the city amended its general plan.
Questions from Lathrop owners and managers
Twenty-four road miles, and the emergency trades still work to a 90 to 120 minute window at any hour of the night. December and January tule fog and harvest truck traffic push a call toward the far end of it. Planned work is a different route: it is scheduled after the request is taken.
To the City of Lathrop Building Department on Towne Centre Drive, through the Lathrop Civic Access Portal, and the contractor assigned to the request files it there. Permits cover new construction, additions, tenant improvements, remodeling and electrical, mechanical and plumbing work, and since 1 January 2026 the 2025 building standards code applies. Floodplain work brings a floodplain development permit as well.
It does. A distribution building in the Crossroads park, a house in River Islands and a rented home off Harlan Road each go in as a separate request and keep their own scope, photographs and schedule, while a manager sees all three in one client area. A single loss needing drying, roofing and a rebuild stays on one file.
Water damage restoration, fire and smoke damage, mold remediation, storm damage and board-up, and biohazard cleanup: five of the twenty-two, carrying the emergency line and the 90 to 120 minute window. The other seventeen, from junk removal and debris hauling to roofing, paving, concrete, construction, remodeling and maintenance, are requested on the form and scheduled.
It can. The City treats reconstruction, rehabilitation or an addition costing more than half the structure's appraised or market value as a substantial improvement, and that work must then be anchored, built of flood-resistant materials and elevated or flood-proofed so the lowest living floor and the mechanical equipment sit at least a foot above the 100-year flood elevation. Grading, cut and fill need their own permit.
