California ADU rules · Los Angeles County
Can I Build an ADU in Palos Verdes Estates?
Yes — you can build an ADU in Palos Verdes Estates. California's statewide ADU law requires every city, including Palos Verdes Estates, to approve a qualifying accessory dwelling unit by right, plus a junior ADU (JADU) on a single-family lot. What varies city to city are the local specifics below.
Can you build one?
ADUs allowed
CA state lawYes — by right
ADUs and JADUs are allowed by right in all residential and mixed-use zones; ministerial approval, no hearing.
Units on a single-family lot
CA state law1 ADU + 1 JADU
At least one ADU and one JADU per single-family lot (a conversion ADU may also be possible).
Units on a multifamily lot
CA state lawConversion ADUs (≥1, up to 25% of units) + up to 8 detached
Conversions of non-livable space (at least 1, or up to 25% of existing units) plus up to 8 detached ADUs on a lot with existing multifamily — never exceeding the number of existing units. JADUs are single-family only.
Junior ADU (JADU)
CA state lawAllowed
Up to 500 sq ft, within the walls of an existing single-family home (single-family lots only).
Size & height
Max detached ADU size
Local rule1,200 sq ft
PVE allows a detached ADU up to 1,200 sq ft (the state default ceiling), not merely the 800 sq ft by-right floor. An attached ADU is limited to the lesser of 1,000 sq ft or 50% of the primary dwelling, subject to the state-protected 850/1,000 sq ft minimums.
Max attached ADU size
CA state law50% of the primary dwelling, but ≥850 sq ft (≥1,000 sq ft for 2+ bedrooms) is always allowed
Guaranteed minimum size
CA state law800 sq ft
An 800 sq ft ADU must be allowed regardless of FAR/lot-coverage caps; a city also cannot cap an attached ADU below 850 sq ft (1,000 for 2+ bedrooms).
Max JADU size
CA state law500 sq ft
Max height
Local rule16 ft
PVE limits ADUs to 16 ft, effectively barring a 2-story detached ADU. State law still requires the city to allow at least 18 ft within ½ mi of a major transit stop or where the primary dwelling is two-story (and 16 ft otherwise); HCD's 4-4-2024 letter flagged PVE's height-measurement method, so confirm how the 16 ft is measured.
Setbacks
Side setback
CA state law4 ft
A city cannot require more than 4 ft side or rear setback; conversions of existing structures are exempt.
Rear setback
CA state law4 ft
Front setback
CA state lawNo front setback may block the mandatory 800 sq ft / 16-ft / 4-ft-setback ADU; otherwise per base zone
Separation from main house
CA state lawNone required
No statewide separation requirement between the ADU and the primary dwelling.
Parking
Parking required
CA state lawUp to 1 space
At most 1 space per ADU (or per bedroom, whichever is less) — and waived in the common cases below.
Transit parking exemption
CA state lawYes — no parking required near transit & for conversions
No parking may be required within ½ mi walking distance of transit, in a historic district, for an ADU within an existing structure, within one block of car-share, or in certain permit-parking areas.
Garage-conversion replacement parking
CA state lawNot required
When a garage/carport is demolished or converted to build an ADU, replacement parking cannot be required.
Approval, timeline & cost
Approval path
CA state lawMinisterial (by right)
No public hearing or discretionary design review for a qualifying ADU.
Approval timeline
CA state law60 days
The agency must act within 60 days of a complete application — and the ADU is deemed approved if it does not.
Owner-occupancy
CA state lawOnly for a JADU
No owner-occupancy requirement for ADUs (the prior sunset was removed). A JADU may require owner-occupancy, principally where it shares sanitation with the main house.
Impact-fee waiver
CA state lawWaived under 750 sq ft
An ADU of 750 sq ft or less pays no impact fees (the 750 sq ft threshold itself is exempt under § 66311.5); larger ADUs pay fees proportional to the primary dwelling. JADUs (≤ 500 sq ft) are exempt.
Permits required
CA state lawBuilding permit
Only a ministerial building permit — no conditional use permit or discretionary design review for a qualifying ADU.
Palos Verdes Estates-specific factors that can change the answer
State law sets the floor, but these local conditions often decide whether a specific parcel works.
Hillside / geotechnical review
PVE is a steep, hillside-built community. A soils/geotechnical report is commonly required for ADUs on sloped lots, areas of significant grading, or with special foundation needs — a real cost and timeline factor even though it cannot be used to deny a code-compliant ADU.
Palos Verdes Homes Association referral
PVEMC § 18.45.040 requires the applicant to provide a copy of the ADU application to the Palos Verdes Homes Association within five days of submittal to the city. The HOA review is a notice/coordination step and cannot lawfully block or unreasonably delay a qualifying ADU (Civ. Code §§ 4740–4741).
Coastal Zone (portions)
Limited coastal-adjacent areas of PVE may fall under Local Coastal Program review; most of the city is not in the Coastal Zone. Confirm parcel-specific coastal status with Planning.
Palos Verdes Estates regulates ADUs in PVEMC Chapter 18.45 (Ord. 020-747, amended by Ords. 760 and 765). Distinctive local rules for this built-out hillside city: detached ADUs are capped at 16 ft (no 2-story, subject to the state transit/two-story exceptions), applications must be copied to the Palos Verdes Homes Association within five days, ADU design must harmonize with the main dwelling, and hillside lots typically trigger a soils/geotechnical report. Single-family lots get one ADU plus one JADU; multifamily detached ADUs are capped at two. HCD's April 4, 2024 review letter required the city to fix its height-measurement method and other items, so confirm the current conformed text with Planning before relying on the printed standards.
