Glendale's Accessory Structures: The Rules That Matter

Every city handles accessory structures a little differently. In Glendale, California, there are 9 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Tiny Homes

Tiny homes on wheels are not permitted as permanent dwellings in Glendale. Fixed tiny homes on a foundation may qualify as ADUs under CA Gov Code 65852.2 and must meet local ADU standards.

Key details: On Wheels: Not allowed as dwelling. On Foundation: May qualify as ADU. State Law: CA Gov Code 65852.2. Max ADU Size: 1,200 sq ft detached.

Unpermitted dwellings: removal or retroactive permitting. Zoning violations: fines and required relocation. Occupancy without certificate: prohibited.

ADU Permits

Glendale processes ADU and JADU applications ministerially under Glendale Municipal Code (GMC) §30.34.080 and California Government Code §65852.2 (as amended by AB 68, AB 881, SB 13, and AB 976). The City Council adopted updated ADU regulations on December 3, 2024 to address California Department of Housing and Community Development (HCD) compliance findings. Detached ADUs are allowed up to 1,200 sq ft and JADUs up to 500 sq ft.

Key details: Code Section: GMC §30.34.080. Last Amended: December 3, 2024 (HCD compliance). Review: Ministerial, 60-day cap. Detached Max: 1,200 sq ft. JADU Max: 500 sq ft.

Building an ADU without a permit is a violation of GMC §30.34.080 and the California Building Standards Code adopted in GMC Title 15, subject to stop-work orders, code-enforcement citations under GMC Title 1, and double permit fees on after-the-fact applications. Unpermitted ADUs cannot use the ministerial path until properly permitted, and may be ineligible for utility service through Glendale Water & Power until corrected.

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

ADU Impact Fees

Glendale exempts ADUs under 750 square feet from all impact fees per California Government Code §65852.2(f)(3). ADUs 750 sq ft or larger pay a Parks and Libraries development impact fee of approximately $4,700 per ADU and other fees proportional to the principal dwelling's gross floor area. School fees are governed by SB 13 (2019). Standard building permit and plan-check fees still apply through Glendale Community Development.

Key details: Under 750 sq ft: All impact fees waived. 750+ sq ft Parks/Libraries Fee: Approx. $4,700 per ADU. Other Fees: Proportional to principal dwelling. State Law: Gov. Code §65852.2(f). School Fees: Proportional under SB 13.

Misrepresenting ADU square footage to claim the under-750 exemption is permit fraud and can void the Certificate of Occupancy. Failure to pay required impact and permit fees results in permit denial and refusal of utility connection by Glendale Water & Power. Post-issuance audits by the city can result in retroactive fee assessments.

The rules around adu impact fees in Glendale lean permissive, but that does not mean anything goes.

ADU Owner Occupancy

Glendale cannot require owner occupancy on standard ADUs permitted after January 1, 2020 because California Government Code §65852.2(a)(6), made permanent by AB 976 (2023), prohibits local owner-occupancy mandates. Junior ADUs (JADUs) under GMC §30.34.080 still require owner occupancy of either the primary dwelling or the JADU because they share walls and utilities, recorded by deed restriction.

Key details: Standard ADU: No owner occupancy (state preempts). JADU: Owner occupancy required. State Law: Gov. Code §65852.2(a)(6); AB 976. Deed Restriction: ADU Covenant Agreement recorded. Condo Conversion (AB 1033): Not adopted by Glendale.

Standard ADU owner-occupancy is preempted by state law — Glendale cannot enforce. JADU owner-occupancy violations can result in revocation of the Certificate of Occupancy, code enforcement under GMC Title 1, and breach of the recorded ADU Covenant Agreement. Misrepresenting JADU occupancy on permit applications is permit fraud and can void the permit.

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

ADU Rental Restrictions

Glendale ADUs may be rented long-term (30 days or more) without a separate license. Short-term rentals under 30 days are prohibited in ADUs citywide under Glendale Municipal Code Chapter 5.56 (Home-Sharing License and Prohibition of Vacation Rentals) and the ADU Covenant Agreement recorded at permit issuance. State law (Gov. Code §65852.2(a)(7)) also restricts STR use of ADUs permitted after January 1, 2020.

Key details: Long-Term (30+ days): Permitted, no separate license. Short-Term (<30 days): Banned in ADUs (GMC Ch. 5.56). Home-Sharing Program: Hosted-stay only, ADUs ineligible. State Law: Gov. Code §65852.2(a)(7). Enforcement: ADU Covenant + Code Compliance.

Operating a Glendale ADU as a short-term rental is a municipal violation under GMC Chapter 5.56 and breach of the recorded ADU Covenant Agreement, with administrative citations and escalating fines under GMC Title 1. Repeated violations can result in revocation of the Certificate of Occupancy, recordation of nuisance notices, and civil enforcement. Platform-based listings are subject to active monitoring and citation.

This is not one of those rules that cities tend to ignore. Glendale actively enforces its adu rental restrictions requirements.

ADU Rules

Glendale regulates ADUs and JADUs under Glendale Municipal Code (GMC) §30.34.080, with the most recent ordinance amendment adopted by City Council on December 3, 2024 to address California HCD compliance concerns. ADUs and JADUs are reviewed ministerially without a public hearing, consistent with California Government Code §65852.2.

Key details: Code Section: GMC §30.34.080. Detached Height: 16 ft (18 ft near transit). Attached Height: 25 ft, max 2 stories. Multifamily Detached New: Up to 2 per lot. Side/Rear Setback: 4 ft (new construction).

Unpermitted ADUs are violations of GMC §30.34.080 enforced by Glendale Community Development, with administrative citations, stop-work orders, and required permitting or restoration. Renting an ADU for less than 30 days violates state ADU law and Glendale's STR rules.

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

Garage Conversions

Glendale allows garage-to-ADU and garage-to-JADU conversions under GMC §30.34.080, consistent with California Government Code §65852.2. No replacement parking is required when an existing garage is converted to an ADU, and the existing setbacks are preserved for the conversion footprint.

Key details: Code Section: GMC §30.34.080; Cal. Gov Code §65852.2. Replacement Parking: Not required. Existing Setbacks: Preserved for conversion. Multifamily Conversion: Up to 25% of existing units. Permit Required: Yes — building permit.

Converting a garage to habitable space without a building permit is a code violation of GMC §30.34.080 and the Building Code, with stop-work orders, fines, and required permitting or restoration. Operating the conversion as a short-term rental (under 30 days) violates state and city rules.

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

Shed Rules

Glendale allows sheds in residential zones. Structures under 120 square feet typically do not require a building permit under California Building Code. Sheds must comply with setback and height requirements.

Key details: Permit Exempt: Under 120 sq ft, one story. Setbacks: Must comply with zoning requirements. Lot Coverage: Counts toward maximum. Habitation: Not permitted.

Sheds violating setbacks or lot coverage receive code enforcement notices. Non-compliant structures must be relocated or removed within the compliance period.

The rules around shed rules in Glendale lean permissive, but that does not mean anything goes.

Carport Rules

Carports in Glendale must comply with zoning setback requirements and obtain a building permit. Carports count toward lot coverage calculations under GMC Title 30.

Key details: Permit: Building permit required. Setbacks: Must meet zone-specific standards. Lot Coverage: Counts toward maximum. Materials: Must match residential character.

Unpermitted carports: stop-work orders, required removal or retroactive permitting with penalty fees. Fines $200 to $1,000.

The Bottom Line

Compared to many U.S. cities, Glendale 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 Glendale 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.
