How Lodi Handles Accessory Structures: A Practical Guide

Lodi maintains 117 local ordinances across all categories, and 9 of those deal specifically with accessory structures. Here is a breakdown of what the city actually requires, what is prohibited, and where Lodi falls on the strict-to-permissive spectrum compared to other cities.

ADU Permits

Lodi processes ADU permit applications through the Building Division per LMC Title 15, and California Government Code Section 66317 requires the city to approve or deny a complete application within 60 days.

Key details: Permit Required: Yes - Building Division. Review Timeline: 60 days (Cal. Gov. Code 66317). Hearing Required: No - ministerial approval only. Planning Phone: (209) 333-6711. Building Phone: (209) 333-6700.

Building an ADU without a permit violates LMC Chapter 15.04 (California Building Code adoption) and triggers stop-work orders and after-the-fact permit fees. If the city fails to act within the state-mandated 60 days, Gov. Code 66317(b) deems the application approved.

The rules around adu permits in Lodi lean permissive, but that does not mean anything goes.

Carport Rules

Carports in Lodi are regulated as accessory structures and as required residential parking. The Phase 3 Incremental Code Update (October 2025) amended LMC 17.32.040 so that required covered parking spaces inside a carport must be independently accessible (no tandem parking).

Key details: Parking code section: LMC 17.32.040. Tandem parking in carport: Not allowed for required spaces (Phase 3 update, Oct 2025). Accessory structure rules: LMC 17.36.120. Setback measurement: LMC 17.14.060.

A carport placed inside a required setback or used to satisfy a covered-parking requirement in a non-conforming tandem configuration violates LMC 17.32.040. Community Development can require relocation, removal, or reconfiguration. Building work performed without a permit is subject to retroactive permits, double fees, and inspection.

ADU Rental Restrictions

Under California Government Code Section 66314(a)(6), ADUs and JADUs in Lodi cannot be rented for terms shorter than 30 days, effectively banning Airbnb-style short-term rentals of accessory units.

Key details: Minimum Rental Term: 30 days. Authority: Cal. Gov. Code 66314(a)(6). Short-term Platforms Allowed: No (Airbnb/VRBO prohibited). Long-term Rentals: Permitted (30+ days). Separate Sale: Prohibited (except SB 9 lot splits).

Short-term rentals of ADUs violate California state law and Lodi's adopted zoning. Code enforcement under LMC Title 17 may issue cease-and-desist orders, and continued violations may lead to administrative citations or revocation of the certificate of occupancy.

ADU Owner Occupancy

Lodi follows California state law: standard ADUs permitted on or after January 1, 2020 carry no owner-occupancy requirement, but Junior ADUs (JADUs) require the owner to live in either the main dwelling or the JADU.

Key details: Standard ADU Owner-Occupancy: Not required. JADU Owner-Occupancy: Required. JADU Deed Restriction: Required and recorded. Authority - Standard ADU: Cal. Gov. Code 66314(a)(7). Authority - JADU: Cal. Gov. Code 66333.

JADU owner-occupancy violations may result in revocation of the JADU permit and recorded deed restriction enforcement under LMC 17.36.130. Standard ADUs have no owner-occupancy requirement to violate.

Lodi is more permissive than most cities when it comes to adu owner occupancy. That said, there are still limits.

ADU Impact Fees

Per California Government Code Section 66315 and confirmed on Lodi's Planning FAQ, ADUs under 750 sq ft pay no city impact fees in Lodi, while ADUs of 750 sq ft or larger pay fees proportional to the primary dwelling's square footage.

Key details: ADUs under 750 sq ft: No city impact fees. ADUs 750+ sq ft: Proportional fees only. Authority: Cal. Gov. Code 66315. County Facilities Fee: LMC Ch. 15.66 may apply. School Fees: May apply for ADUs over 500 sq ft (Ed. Code 17620).

If Lodi were to charge prohibited impact fees, the applicant could recover them under California Gov. Code 66020 (Mitigation Fee Act protest procedure). There is no enforcement action against property owners - this provision restricts the city, not the homeowner.

Lodi is more permissive than most cities when it comes to adu impact fees. That said, there are still limits.

Tiny Homes

Lodi has no separate "tiny home" ordinance. Tiny dwellings on a permanent foundation are permitted as ADUs under LMC 17.36.130 (up to 800 sq ft for one-bedroom, 1,000 sq ft for multi-bedroom) or as JADUs up to 500 sq ft within an existing home, including four free pre-approved city plans as small as 375 sq ft.

Key details: ADU max size (1-bed): 800 sq ft. ADU max size (2+ bed): 1,000 sq ft. JADU max size: 500 sq ft (within existing walls). Smallest pre-approved plan: 375 sq ft studio. ADU side/rear setback: 4 ft.

Occupying a tiny house on wheels or a recreational vehicle as a permanent residence on a Lodi residential lot violates LMC Title 17 land-use provisions and may be cited as an unlawful occupancy. Constructing a tiny home as an ADU without a permit triggers stop-work and retroactive permitting, with inspections under Title 24 (energy, egress, fire) before occupancy.

The rules around tiny homes in Lodi lean permissive, but that does not mean anything goes.

ADU Rules

Lodi allows attached, detached, converted, and junior ADUs on single-family lots under LMC 17.36.130, with state-aligned size caps of 800 sq ft (studio/1BR) or 1,000 sq ft (2BR+) and 4-foot side/rear setbacks.

Key details: Code Section: LMC 17.36.130. Max ADU Size: 800 sq ft (1BR) / 1,000 sq ft (2BR+). Max JADU Size: 500 sq ft. Side/Rear Setback: 4 feet. Pre-approved Plans: 4 free city-issued floor plans.

Construction of an ADU without permits is treated as unpermitted construction under Lodi Municipal Code Title 15. Violators must obtain after-the-fact permits (typically at double the original fee) or remove the structure. Per California Health & Safety Code Section 17980.12, code enforcement for unpermitted ADUs built before 2020 must allow a 5-year compliance period before requiring correction.

If you are coming from a city with tighter rules, you will find Lodi gives residents more flexibility on adu rules.

Shed Rules

Lodi regulates residential accessory structures (sheds, gazebos, workshops) under LMC 17.36.120, with setback measurements set by LMC 17.14.060. The California Building Code (CBC 105.2) exempts one-story sheds 120 sq ft or under from a building permit, but city zoning setbacks still apply.

Key details: Permit-exempt size: Up to 120 sq ft (CBC 105.2). Local code section: LMC 17.36.120. Setback code section: LMC 17.14.060. Habitation allowed: No. Electrical to shed: Separate electrical permit required.

Constructing an oversize shed without a permit, or placing a shed inside the required setback, is a zoning/building code violation enforced by the Lodi Community Development Department. Standard remedies include a stop-work notice, retroactive permit application with double fees, or an order to relocate or remove the structure. Continued non-compliance may be cited as a municipal infraction under LMC Title 1 enforcement provisions.

Garage Conversions

Lodi expressly permits garage-to-ADU and garage-to-JADU conversions under LMC 17.36.130 and the city's published ADU program. Under California Government Code 65852.2, the city cannot require replacement parking when an existing garage is converted to an ADU.

Key details: Code section: LMC 17.36.130. Replacement parking required: No (Cal. Gov. Code 65852.2). JADU max size: 500 sq ft within existing walls. Detached structure to JADU: Not allowed. Owner-occupancy for JADU: Required (recorded deed restriction).

Performing a habitable garage conversion without permits is a building and zoning violation. Lodi Community Development will require a retroactive ADU permit application, inspections to verify Title 24 energy, egress, smoke alarm, and fire-separation compliance, and may issue a stop-work order or red-tag the unit until corrected. Owner-occupancy violations on a JADU constitute a breach of the recorded deed restriction required by LMC 17.36.130.

If you are coming from a city with tighter rules, you will find Lodi gives residents more flexibility on garage conversions.

The Bottom Line

Compared to many U.S. cities, Lodi gives residents more room on accessory structures. 6 of the 9 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.

Keep in mind that Lodi can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
