What the Lathrop permit process actually involves — and how KHB carries your project through it, from drawings to final inspection.
Home › Plans & Permits › Lathrop
Building permits in Lathrop are issued by the Building Department at 390 Towne Centre Drive (209‑941‑7200), with applications, plan submittals, and status tracking handled through the city’s online Lathrop Civic Access Portal (LCAP). Plan check fees apply to projects requiring review, per the city’s master fee schedule. Two expiration clocks matter: an application that hasn’t been issued is valid for 180 days, and an issued permit is valid 12 months from issuance — it expires if inspections aren’t performed. Review cycle times stretch during high-volume periods, so a complete first submittal is the best schedule insurance.
KHB prepares the full residential set — architectural, structural with calcs, Title 24, site plan — files it through LCAP, clears corrections, and builds the project as your licensed GC (CSLB #1070537).

Lathrop adds a layer most valley cities don’t: in River Islands and other master-planned areas, HOA design review runs alongside city plan check, each with its own package and timeline. Homeowners who file one and forget the other lose weeks. We run both tracks in parallel — and we watch the 180-day application clock and the 12-month permit clock so a slow decision never quietly kills your approval. Modern housing stock keeps the drawings clean; the process is what needs managing here.
Whether your plans are stamped and ready or still half-finished, KHB picks up the Lathrop permit process at any stage: completing construction documents (structural, Title 24 energy, site plan), filing the submittal, answering plan check corrections, paying and pulling the permit, and scheduling every inspection through final sign-off. And because we’re a licensed design-build general contractor (CSLB #1070537), the company handling your paperwork is the company that builds the project — see our general contractor services in Lathrop.

An application (not yet issued) is valid 180 days; an issued permit is valid 12 months and expires if inspections aren’t performed. We schedule the work so neither clock runs out.
