San Joaquin County Development Title 9 generally prohibits external signage for home occupations in residential zones. No signs advertising a home business may be visible from the street or neighboring properties.

San Joaquin County property maintenance code requires garage/yard sales to avoid creating blight conditions. Merchandise must be displayed in an organized manner and fully removed from public view at the end of each sale day. Unsold items at the curb past the sale end-date can trigger blight citations under Development Title property standards.
San Joaquin County (Central Valley, elevation ~20 ft) experiences snow only rarely. There is no sidewalk snow-removal ordinance because measurable snow is essentially absent — the last significant Stockton snowfall was a trace event decades ago. Property owners remain responsible for general sidewalk maintenance, tripping hazards, and overhanging vegetation.
San Joaquin County does not operate a county-level rental registration program in unincorporated areas, but Stockton requires landlords to participate in the Rental Housing Inspection Program (Stockton Municipal Code §8.56) with annual fees per unit and periodic inspections. Lodi and Manteca rely on complaint-driven inspections rather than mandatory registration. All landlords must maintain habitability under California Civil Code §1941.1.
San Joaquin County does not impose county-level rent control in unincorporated areas, but the statewide Tenant Protection Act of 2019 (AB 1482) caps annual rent increases at 5% plus CPI (max 10%) for most rentals built before 2009 occupied 15+ years. Stockton, Lodi, Manteca, and Tracy follow AB 1482 without additional local rent caps. Single-family homes, condos, and newer construction are generally exempt unless owned by a corporation or REIT.
All covered rentals in San Joaquin County — Stockton, Lodi, Manteca, Tracy, and unincorporated areas — are subject to the statewide just-cause eviction rules in AB 1482 (Civil Code §1946.2). After 12 months of tenancy, landlords must state a recognized at-fault or no-fault reason to terminate, and no-fault evictions require one month of rent as relocation assistance. No city in the county has enacted additional local just-cause protections.
Unincorporated San Joaquin County allows temporary garage sale signs up to 4 square feet on the sale property and a limited number of directional signs, but prohibits attaching signs to utility poles, traffic signs, or placing them in the public right-of-way.

Stockton, Lodi, and Manteca have parallel rules in their respective sign codes.
Tree removal permits in San Joaquin County trigger replacement planting at ratios from 1:1 to 10:1 depending on size and species. Native oaks require native oak replacement — typically 3:1 for standard oaks and 5:1–10:1 for heritage. An in-lieu fee paid to the SJ Oak Woodlands Conservation Fund is allowed where on-site replanting is infeasible.
San Joaquin County recognizes heritage native oaks (typically 24-inch+ DBH valley oaks, blue oaks, interior live oaks) under the Oak Woodlands Ordinance, with stricter protections and 5:1 to 10:1 mitigation. Removal requires Planning Commission approval absent an imminent-safety finding. The Delta riparian corridor hosts many heritage oaks subject to additional CEQA review.
San Joaquin County protects native oaks (valley oak, blue oak, interior live oak) through the Oak Woodlands Ordinance. Removal of oaks with trunk diameter 6 inches+ DBH generally requires a permit from Community Development, with mitigation. Commercial orchards and ag operations are exempt under the Right to Farm Act. Street trees in maintained districts are county-controlled.
Unincorporated San Joaquin County regulates outdoor lighting under the Development Title dark-sky and glare provisions, requiring fixtures to be shielded so that light does not spill onto adjoining properties or across roadways. Lighting near rural AG-zoned land and the Lodi AVA wineries must avoid measurable illumination at property lines, and violations are handled by Community Development code enforcement as nuisance cases.
San Joaquin County Development Title requires outdoor lighting to be fully shielded (full-cutoff), directed downward, and not spill across property lines. Glare into public roadways is prohibited. LED color temperature is encouraged at 3000K or below. Lighting near Stockton Metropolitan Airport must not interfere with pilot night vision or airfield lighting.
San Joaquin County and its cities enforce juvenile curfew ordinances for minors under 18 under authority of California Welfare & Institutions Code §625.5.

Erosion and sediment control is required on all grading and construction sites in San Joaquin County. Grading permits include an erosion control plan per the CASQA BMP Handbook. Sediment discharge to Delta waters violates Porter-Cologne and the Clean Water Act, with substantial Regional Board fines. Wind erosion controls are critical on the valley floor.
San Joaquin County is inland and has NO California Coastal Commission jurisdiction — no coastal zone extends into the county. However, Delta waterfront development on the San Joaquin River, Mokelumne River, and Delta islands is regulated by the Delta Stewardship Council, Delta Protection Commission, Central Valley Flood Protection Board, and the U.S. Army Corps of Engineers.
San Joaquin County operates under a Phase II MS4 NPDES permit from the Central Valley Regional Water Board. Construction disturbing 1+ acre needs a SWPPP and coverage under the CGP.

County film permits required for commercial aerial filming on county property; agricultural spraying falls under Part 137 and Ag Commissioner rules.
Recreational drone use in San Joaquin County follows FAA rules (49 USC §44809): register drones over 0.55 lbs, fly under 400 ft AGL, keep visual line of sight, stay out of Stockton Metropolitan Airport (KSCK) and Tracy Municipal (KTCY) controlled airspace without LAANC authorization. County parks prohibit drone launch/landing without a permit.
San Joaquin County Development Title limits residential structures to 35 feet in most zones. Agricultural zones allow taller ag buildings (barns, silos) to 50 feet by right. Chimneys, antennas, and solar arrays may exceed height limits by up to 10 feet. Stockton Metropolitan Airport FAR Part 77 surfaces further restrict heights near the airport.
San Joaquin County Development Title establishes minimum setbacks by zoning district. Typical residential setbacks: R-L 20 ft front, 5 ft side, 15 ft rear; R-R 25 ft front, 10 ft side, 20 ft rear. Agricultural zones require 50 ft front and 30 ft side from all structures. Corner-lot side-street setbacks are increased. State ADU law (Gov Code §65852.2) overrides for 4-ft ADU setbacks.
San Joaquin County Development Title limits building lot coverage: R-L residential typically 40%, R-R 25%, AG 10%. Impervious surface totals trigger stormwater requirements under Regional Water Board MS4 permit when exceeding 2,500 sq ft (SWPPP threshold) or 5,000 sq ft of net new impervious area.
Unincorporated San Joaquin County garage/yard sales are limited to daytime hours, typically 7:00 AM to sunset or 7:00 PM (whichever is earlier). All merchandise, tables, and signs must be stored out of public view at the end of each sale day. Items left curbside after sale hours may trigger blight citations.
San Joaquin County Development Title limits household garage/yard sales in unincorporated residential zones to 3 per calendar year, each not exceeding 3 consecutive days. Neighborhood-wide sales count as one event for each participating household. Exceeding limits triggers reclassification as a home occupation requiring zoning approval.
San Joaquin County does not require a formal garage sale permit in unincorporated areas for residents' occasional personal-property sales. Sellers must comply with frequency limits (3 per household per year), time restrictions, and sign rules. Commercial resale activity triggers home-business zoning requirements.
