Accessory Structures in Palmdale, CA

If you live in Palmdale or are thinking about moving there, accessory structures are one of those things you probably won't think about until they affect you directly. Palmdale has 5 specific rules on the books covering different aspects of accessory structures, and some of them might surprise you.

ADU Rental Restrictions

Palmdale bars short-term rentals of accessory dwelling units and junior ADUs outright: every rental period must run at least 31 days, and JADU owners must record that restriction with the County before getting a permit.

Key details: Minimum rental term: 31 days, ADU and JADU alike. Applies to: Both accessory dwelling units and JADUs. JADU condition: Recorded covenant required before permit issues. Recording office: Los Angeles County Recorder. Noncompliance remedy: Legal action against the property owner.

Renting a Palmdale ADU or JADU for stays under 31 days breaches the recorded covenant on JADUs and the zoning standard for ADUs generally; the City Attorney can pursue legal action against the property owner under § 17.91.010(E)(4)(c), and code enforcement can separately cite the zoning violation under Title 17 permit-condition enforcement procedures.

ADU Impact Fees

Palmdale charges zero impact fees on any junior accessory dwelling unit and on any accessory dwelling unit under 750 square feet; larger ADUs still owe a full new-dwelling utility connection fee if built alongside a new single-family home.

Key details: JADU impact fees: None, regardless of size. ADU impact fee waiver threshold: Under 750 square feet. Larger new-construction ADUs: Owe normal connection fee/capacity charge. Existing-structure ADUs: No separate utility connection required. Septic connections: Need County Public Health Dept. approval.

Because the fee waiver is self-executing under § 17.91.010(E)(6)(b), the City cannot lawfully impose an impact fee on a qualifying unit; a property owner improperly billed for impact fees on a sub-750-square-foot ADU or a JADU can challenge the charge through the Planning Division's permit review process for the underlying zoning clearance.

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

ADU Owner Occupancy

Palmdale requires the property owner to live on-site whenever a junior accessory dwelling unit shares a bathroom with the main house, occupying either the primary residence or the JADU itself as their principal residence, with narrow exceptions for public agencies and land trusts.

Key details: Trigger: JADU shares bathroom with main house. Who must live on-site: Owner, in main house or JADU. State law basis: Government Code § 66333(b). Exceptions: Government agency, land trust, housing organization. JADU parking: Not required, § 17.91.010(G)(3).

Failure to maintain owner-occupancy where required breaches the recorded covenant filed under § 17.91.010(E)(4), which the code makes binding on successors in ownership; noncompliance exposes the property owner to legal action under § 17.91.010(E)(4)(c) for violating the standards governing junior accessory dwelling units.

Shed & Carport Rules

Detached sheds, garages, and workshops in Palmdale must sit outside required front, side, and rear setbacks under PMC § 17.82.020, using Table 17.82.020-1's height-based rule: a rear or interior-side setback of 5 feet applies to structures 10 feet tall or shorter, rising to 10 feet for anything taller, plus a 15-foot alley clearance for detached garages.

Key details: Setback, structures ≤ 10 ft tall: 5 ft rear/interior side. Setback, structures > 10 ft tall: 10 ft rear/interior side. Garage/carport near alley: 15 ft from alley center line. Kitchens: Indoor cooking facilities prohibited. Plumbing allowed: Washer, dryer, toilet, shower, sink.

A shed, garage, or workshop that encroaches into the required setback, exceeds the height-based setback pairing in Table 17.82.020-1, or is fitted out with a kitchen or living quarters is out of compliance and subject to code enforcement correction. If a detached structure is later attached to the main building by a common wall or continuous roofline, PMC § 17.82.020(A)(3) reclassifies it as part of the main structure, meaning it must then meet the full primary-building setback and height standards rather than the more permissive accessory limits.

ADU Rules

Palmdale allows one ADU and one JADU per single-family lot under PMC § 17.91.010, approved ministerially through zoning clearance review rather than a discretionary hearing. Detached ADUs top out at 1,200 square feet and 16 feet in height (18 feet near transit), with just a 4-foot side/rear setback, or none at all for conversions of existing space.

Key details: Detached ADU max size: 1,200 sq ft. Detached ADU max height: 16 ft (18 ft near transit). ADU setback: 4 ft side/rear (0 ft for conversions). Minimum rental term: 31 days. Impact fee waiver: ADUs/JADUs under 750 sq ft.

Before a JADU permit issues, the owner must record a declaration with the County Recorder, approved by the City Attorney, restricting the unit from being sold separately from the primary residence and from being rented for less than 31 days; failing to comply with those recorded restrictions exposes the owner to legal action under § 17.91.010(E)(4)(c). Standard ADUs carry the same 31-day minimum rental floor and cannot be conveyed apart from the primary residence except as authorized by Government Code § 66340.

The Bottom Line

Palmdale's accessory structures rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Palmdale is broadly strict or permissive.

Keep in mind that Palmdale 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.
