Accessory Structures in Tracy, CA: What Residents Actually Need to Know

If you live in Tracy or are thinking about moving there, accessory structures are one of those things you probably won't think about until they affect you directly. Tracy has 4 specific rules on the books covering different aspects of accessory structures, and some of them might surprise you.

Carport Rules

Carports in Tracy are regulated as accessory structures under Tracy Municipal Code Chapter 10.08 (Zoning Regulations). TMC 10.08.180 defines the carport, and detached accessory building rules in the residential zones (e.g., LDR Article 7) govern placement, separation, and yard location. Building permits and California Building Code apply to construction.

Key details: Code Section: TMC 10.08.180. Zoning Chapter: TMC Chapter 10.08. LDR Detached Accessory Rule: TMC 10.08.1220(b). Building Separation: 6 ft (TMC 10.08.1220(d)). Rear Yard Location: Rear one-third or 70 ft from front.

Building or expanding a carport without a permit, encroaching on front or street-side setbacks, exceeding the 45 percent LDR lot coverage, violating the six-foot accessory separation, or placing a detached carport outside the rear one-third of the lot can trigger code enforcement, stop-work orders, and required removal or correction. Unpermitted conversion to a garage or habitable space is separately citable.

Shed Rules

Sheds up to 120 square feet without electricity or plumbing generally do not require a building permit in Tracy under California Building Code exemptions. All sheds must comply with TMC Title 10 zoning setbacks.

Key details: Permit Exempt: Up to 120 sq ft, no utilities. Permit Required: >120 sq ft or with electrical/plumbing. Setbacks: Must comply with TMC Title 10. Contact: Building Safety or Planning (209) 831-6400.

Unpermitted shed that requires a permit: stop-work order, retroactive permit fees, and possible removal if non-compliant.

Tracy is more permissive than most cities when it comes to shed rules. That said, there are still limits.

Garage Conversions

Garage conversions in Tracy creating an ADU are permitted by right under state law with no replacement parking required. Under SB 987, permits for demolishing a detached garage and building an ADU must be reviewed simultaneously. Building permits are required.

The Bottom Line

Compared to many U.S. cities, Tracy gives residents more room on accessory structures. 2 of the 4 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.

These rules come from Tracy's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
