Zoning, building permits and septic rules in Lodi, California

Lodi, California issues its own building permits through the City's Building Division, and the City sets zoning for residential districts inside city limits12. Septic permits for addresses inside Lodi come from San Joaquin County Environmental Health, not the City3. Overnight RV occupancy on private property is limited to approved RV parks or temporary use permits during construction4.

Do you need a building permit in Lodi, CA?

Yes, for work the City permits. Lodi's Building Division lets contractors get certain simple residential permits, such as plumbing water heater replacement, mechanical HVAC replacement and reroofing, online through eTRAKiT1.

Accessory dwelling units and junior accessory dwelling units inside Lodi city limits require a building permit, subject to the standard application and processing fees and procedures that apply to building permits generally5.

We could not confirm Lodi's list of every project that needs a permit, its permit fees, or its owner-builder rules; call the Building Division at (209) 333-671410.

Who issues building permits in Lodi, and how do you reach them?

The City of Lodi Building Division issues building permits for land inside city limits. Call (209) 333-6714; contractors must set up an eTRAKiT account before applying online101.

San Joaquin County's Community Development Department handles building permits only for unincorporated land, so it is not the office for a lot inside Lodi11. Septic permits are the exception: they come from the county, covered below.

Does Lodi have zoning, and what does it mean for lot size and height?

Yes. Lodi's development code sets residential district standards in a table covering the RLD low-density, RMD medium-density and RHD high-density districts2.

For a single-family lot, the minimum area is 5,000 square feet in RLD7, 5,000 square feet in RMD12, and 4,000 square feet in RHD13. Site coverage is capped at 45 percent in RLD, 50 percent in RMD and 60 percent in RHD14. In RLD, buildings may be 2 stories and no more than 35 feet8.

Each approved parcel in a subdivision must be provided connections to public utilities, including wastewater9.

How do septic permits work in Lodi?

San Joaquin County Environmental Health's Liquid Waste Program oversees the design, construction and installation of onsite wastewater treatment systems throughout San Joaquin County, including inside Lodi3. Apply to install a new residential septic system through the county6. Call (209) 468-342015.

Because Lodi requires public utility connections including wastewater for approved subdivision parcels, a septic system is mainly relevant for existing lots without sewer service9. Only 6.5 percent of San Joaquin County soils avoid severe limits for a conventional drain field, so expect an engineered system16.

Water wells also need a county permit17.

Can you live in an RV or tiny home on your land in Lodi?

Not casually. Lodi does not allow a recreational vehicle to be parked for overnight occupancy except in an approved RV park, or with temporary use permit approval as a temporary dwelling during construction on the same site4.

Camping or maintaining an encampment on public property, including any street, sidewalk, park, parking lot or open space, is prohibited18. We could not confirm a Lodi rule on tiny-home occupancy; ask the Building Division at (209) 333-671410.

Building a home in Lodi: the steps, in order

  1. Identify the zoning district and check lot area, coverage and height limits2.
  2. Confirm public wastewater and utility connections; if none exist, start with San Joaquin County Environmental Health915.
  3. Apply for the building permit with the Building Division10.
  4. If you plan to live in an RV while building, request temporary use permit approval first4.
  5. Ask the Building Division how to schedule inspections; contractors can use the City's eTRAKiT system110.

What stays with San Joaquin County, and what to check before you buy in Lodi?

Septic systems and wells stay with San Joaquin County Environmental Health, even for addresses inside Lodi317. The county's accessory dwelling rules apply to unincorporated lots, while Lodi's ADU rules come from the City195.

Before buying, confirm the zoning district, whether the lot is on public sewer, and the City's rules for the RV or accessory dwelling you plan. We could not confirm Lodi rules on driveway access, short-term rentals, agricultural exemptions or minimum dwelling size10.

Watch-outs

  • Overnight RV occupancy on private land is restricted, so do not plan to live in an RV on a Lodi lot without temporary use permit approval4.
  • We could not confirm Lodi's building permit fees; the Building Division at (209) 333-6714 can quote them10.
