Building an ADU in Rancho Palos Verdes. Rules, costs, timeline.
What RPVMC Chapter 17.10 actually allows, how the Very High Fire Hazard Severity Zone and Coastal Zone overlays change a Peninsula build, and what an all-in ADU costs on a Rancho Palos Verdes lot in 2026.
What you can build — at a glance
Max ADU size
850 sqft (1BR) / 1,000 sqft (2BR+) detached · attached the lesser of 50% of primary or those caps · 500 sqft JADU (RPVMC § 17.10.020.C.2–3)
Detached height
16 ft · 18 ft within ½ mi of transit or on a multistory multifamily lot · +2 ft to match primary roof pitch (RPVMC § 17.10.020.C.4.a; Gov. Code § 66321(b)(4))
Attached height
The lesser of the primary’s limit or 25 ft (RPVMC § 17.10.020.C.4.b; Gov. Code § 66321(b)(4)(D))
Side & rear setbacks
4 ft new construction · 0 ft for a conversion (RPVMC § 17.10.020.C.1; Gov. Code § 66314(d)(7))
Units per SFR lot
Up to three: a conversion ADU + a JADU + a new detached ADU ≤800 sqft (Gov. Code § 66323; HCD ADU Handbook, p. 17). Local § 17.10.020.B.1 reads “one ADU and one JADU” — state law preempts; RPVMC § 17.10.040 carries the full stack.
Parking required
One space, with five state exemptions (transit, historic, conversion, no on-street permit, car-share) (RPVMC § 17.10.020.C.11; Gov. Code § 66322)
Permit timeline
60 days · ministerial review, no hearing (RPVMC § 17.10.050.B; Gov. Code § 66317)
VHFHSZ fire rules
Lots in a Very High Fire Hazard Severity Zone must meet California Building Code Chapter 7A wildfire-hardening standards (RPVMC § 17.10.020.C.1). Fire-code authority survives ADU-statute preemption.
DetachedUp to 1,000 sqft (2BR+) · 16 ft (18 ft transit/multifamily; +2 ft roof pitch)
AttachedUp to 1,000 sqft (2BR+), capped at 50% of the primary’s floor area · up to 25 ft
Garage conversionWithin the existing permitted garage footprint · no replacement parking required
Interior conversionCarved out of existing primary-dwelling or accessory-structure space
Junior ADUUp to 500 sqft inside the primary dwelling (Gov. Code § 66313(d))
Per RPVMC § 17.10 and Gov. Code §§ 66310–66342. Cross-checked against the HCD ADU Handbook (March 2026). Full citations in the sections below.
Three documents govern an ADU project in Rancho Palos Verdes.
We read all three before we draw a line on a Peninsula lot.
State law. California Government Code
§§ 66310–66342. The statewide ADU statute,
substantively amended by SB 543 and AB 1154 (both effective
January 1, 2026). It sets the floor every California city
must meet.
Local ordinance. Rancho Palos Verdes
Municipal Code Chapter 17.10 (Accessory Dwelling Unit and
Junior Accessory Dwelling Unit Development Standards). The
city’s rules layered on top of state law —
including the size and height caps, the Very High Fire Hazard
Severity Zone wildfire-hardening rule, and the recorded-covenant
requirement.
HCD commentary. The California Department of
Housing and Community Development ADU Handbook (March 2026)
plus its enforcement letters. HCD has authority under
Gov. Code § 66316 to challenge ordinances that don’t
comply with state law — its interpretation controls when
a local rule reads more narrowly.
The city’s Planning Division (30940 Hawthorne Boulevard,
(310) 544-5228) administers the ordinance. Chapter 17.10 is
published in the codified municipal code at
library.municode.com,
and the city maintains an
official ADU and JADU page.
What you can build in Rancho Palos Verdes
Everything in this section is grounded in RPVMC Chapter 17.10
and the City’s ADU and JADU guidance, with state-law
citations called out where they preempt or supplement the local
rule. We won’t re-cite the local chapter on every line;
assume it under each subsection unless we tell you otherwise.
ADU applications here are ministerial — building permit
only, no hearing (RPVMC § 17.10.050.B and Gov. Code
§ 66317).
Number of units permitted
The headline rule in § 17.10.020.B.1 says one ADU and one
JADU per single-family lot. But that is the narrower of the two
pathways the same chapter offers. The state-exemption pathway in
§ 17.10.040 — which tracks Gov. Code § 66323
— requires the city to allow a conversion ADU, a JADU, and
a separate new detached ADU of up to 800 square feet to be
combined on the same single-family lot. The HCD ADU Handbook
(March 2026, p. 17) is explicit: cities must allow “at
least one ADU constructed from existing space, one JADU, and one
newly constructed detached ADU.” Where the
one-ADU-plus-one-JADU language is applied more narrowly, state
law preempts it.
On multifamily lots, the ordinance allows conversion ADUs up to
25% of existing units plus up to two detached ADUs
(§ 17.10.020.B.2). State law goes further: SB 1211
(effective January 1, 2025) amended Gov. Code § 66323 to
allow up to eight detached ADUs on a lot with an
existing multifamily dwelling — not to exceed the number of
existing units. On a multifamily parcel, the state-law cap
governs.
Size limits
Per § 17.10.020.C.2–3, a detached ADU is capped at
850 square feet for a studio or one-bedroom unit, or 1,000 square
feet with more than one bedroom. An attached ADU is the lesser of
50% of the primary residence’s floor area or those same
850 / 1,000 square-foot caps. A JADU is capped at 500 square feet
(Gov. Code § 66313(d)). State law protects an 800-square-foot
floor regardless of local lot-coverage, floor-area-ratio, or
open-space limits (Gov. Code § 66321(b)(3)) — even if
your primary dwelling has consumed the lot’s allowance, you
are still entitled to 800 square feet of new ADU floor area.
Setbacks
Side and rear setbacks are 4 feet for new construction and 0 feet
for a conversion or a structure rebuilt to the same footprint
— matching the state-law floor in Gov. Code
§ 66314(d)(7). One Peninsula-specific note: the same
subsection (§ 17.10.020.C.1) requires lots in a Very High
Fire Hazard Severity Zone to meet California Building Code
Chapter 7A wildfire-hardening standards. That rule changes how an
ADU is built, not whether it is allowed — see the dedicated
fire-zone section below.
The Wilshire
— 400 sqft Studio/1BA. A single-story footprint that sits
comfortably inside the 16 ft detached cap in RPVMC
§ 17.10.020.C.4 and pairs cleanly with the Peninsula’s
stucco-and-tile housing stock.
Maximum height
A detached ADU is capped at 16 feet, rising to 18 feet on lots
within one-half mile of a major transit stop or high-quality
transit corridor, or on lots with a multistory multifamily
dwelling — with an additional 2 feet allowed to match the
primary dwelling’s roof pitch (Gov. Code
§ 66321(b)(4)). An attached ADU may reach the lesser of the
primary’s height limit or 25 feet (Gov. Code
§ 66321(b)(4)(D)). Roof decks are not permitted on a
detached ADU (§ 17.10.020.C.17).
What this means for design: Rancho Palos Verdes is a single-story
detached-ADU market. Our six single-story Signature Homes are
designed for exactly this 16–18 ft envelope. Our three
two-story plans are sold as detached-only structures that need
roughly 25 feet of detached height to permit — that
envelope doesn’t exist on a Rancho Palos Verdes lot, so the
two-story plans sit out here. We don’t market the local
25-foot attached envelope as a path to those plans; we don’t
offer them as attached ADUs.
Parking
One off-street space is required for an ADU, but
§ 17.10.020.C.11.b waives it under any of the five state
exemptions in Gov. Code § 66322: the ADU is within one-half
mile of transit, inside a historically significant structure,
part of the existing primary residence, in an on-street permit
area where the occupant isn’t offered a permit, or within
one block of a car-share. When a garage is demolished or converted
to build the ADU, no replacement parking may be required
(Gov. Code § 66314(d)(11)). A JADU never requires parking
(Gov. Code § 66334(a)). The ordinance also allows tandem and
setback-area parking unless the city makes a specific
site-or-fire-safety finding (§ 17.10.020.C.11.c).
Lot coverage and FAR
Per § 17.10.020.A, the city may not apply lot-coverage,
floor-area-ratio, open-space, front-setback, or minimum-lot-size
rules in a way that blocks an 800-square-foot ADU with 4-foot
side and rear setbacks. This mirrors the statewide protection in
Gov. Code § 66321(b)(3). On the Peninsula’s larger
lots this is rarely the binding constraint — but it matters
on a tight parcel where the primary dwelling already fills the
envelope.
The Westwood
— 1 BR, 550 sqft. A single-story plan that stays inside
the 16 ft detached envelope and works on a Peninsula
hillside lot where keeping the ADU low protects neighbors’
ocean views.
Owner-occupancy
A standard ADU carries no owner-occupancy requirement, consistent
with state preemption under Gov. Code § 66315. A JADU does:
§ 17.10.030.A.2 requires the owner to live in either the
main house or the JADU. But AB 1154 (effective January 1, 2026)
narrowed the JADU owner-occupancy mandate at Gov. Code
§ 66333(b) to JADUs that share sanitation facilities with the
primary dwelling. A JADU with its own dedicated bathroom is no
longer subject to the requirement under state law — even
though the RPV ordinance still describes the broader pre-2026
rule. State law preempts the older local language.
Impact fees
Per § 17.10.020.G, ADUs and JADUs under 750 square feet pay
no impact fees (matching Gov. Code § 66318). An ADU of 750
square feet or more pays impact fees proportional to the primary
dwelling’s square footage — not a flat per-unit
charge. An ADU is not treated as a new residential use for
utility connection or capacity charges unless it is built with a
new single-family dwelling.
Permitting timeline
The city has 60 days from a complete application to approve or
deny, with no hearing (§ 17.10.050.B; Gov. Code
§ 66317). Miss the deadline and the application is deemed
approved. SB 543 (effective January 1, 2026) requires the city to
determine completeness within 15 business days. The full sequence
is in the permit section below.
ADUs in the Very High Fire Hazard Severity Zone
The Palos Verdes Peninsula is hilly, dry, and brush-covered
— much of Rancho Palos Verdes has long carried a Very High
Fire Hazard Severity Zone (VHFHSZ) designation. In 2025 the city
adopted Ordinance 691, approving the updated CalFire / Office of
the State Fire Marshal (OSFM) Fire Hazard Severity Zone map. The
new map — effective January 1, 2026 — removes some
areas from the Very High tier under updated climate modeling, but
significant VHFHSZ acreage remains across the Peninsula. The fire
authority is the Los Angeles County Fire Department.
Here is the rule that matters most, because it is the one most
often gotten wrong: a fire-zone designation does not
block an ADU that state law protects. Per RPVMC
§ 17.10.020.C.1, a lot in a VHFHSZ must build to the
wildfire-hardening standards in California Building Code Chapter
7A (Title 24, Part 2) — ignition-resistant siding and
roofing, ember-resistant vents, tempered or multi-pane glazing,
and similar measures. That changes how the ADU is built.
It does not change whether you may build it.
What survives preemption — and what doesn’t
California Fire Code provisions and Public Resources Code
§§ 4201–4204 give local jurisdictions authority to
impose stricter fire-safety rules in state-designated VHFHSZs.
CalFire and OSFM publish the official zone maps. Rules tied to
that fire-code authority — the Chapter 7A wildfire-hardening
standards, fire-apparatus access, and the county fire
department’s setback review under § 17.10.050.F
— survive the ADU statute’s preemption rules. They
rest on fire-code authority, not on ADU-zoning authority.
Two ordinary ADU rules do not get stricter just because
the lot is in a fire zone:
Fire sprinklers. An ADU is not required to have
sprinklers unless the primary residence already requires them,
and building an ADU never triggers a sprinkler retrofit of the
main house (RPVMC § 17.10.020.C.14; Gov. Code
§ 66314(d)(13)). A VHFHSZ designation by itself does not
change that. If the county fire department conditions sprinklers
on a specific lot, it must rest on an applicable fire-code
provision — not on the ADU’s existence.
Parking and access. The five parking exemptions
in Gov. Code § 66322 still apply on a fire-zone lot, and
garage-conversion replacement parking is still preempted
(Gov. Code § 66314(d)(11)). The ordinance does allow the
city to deny tandem or setback-area parking where it makes a
specific fire-and-life-safety finding (§ 17.10.020.C.11.c)
— that finding must be specific to the site, not a blanket
fire-zone rule.
The honest summary: in a VHFHSZ, expect Chapter 7A
wildfire-hardening to add cost and design constraints, and expect
the county fire department to review apparatus access and
setbacks. Do not accept a flat “you can’t build an ADU
in the fire zone” — state law protects the ADU; the
fire code shapes it. We verify each lot’s current CalFire /
OSFM designation and price the Chapter 7A measures only where the
map actually applies.
Coastal Zone permits on the Peninsula
Rancho Palos Verdes wraps the southern tip of the Palos Verdes
Peninsula, and parts of the city sit inside the California Coastal
Zone. For those parcels, the Coastal Act adds a layer on top of
the ADU permit. Per RPVMC § 17.10.050.H, nothing in the ADU
ordinance supersedes the California Coastal Act (Pub. Resources
Code § 30000 et seq.).
A property inside the Coastal Zone may need a Coastal Development
Permit (CDP) in addition to the ministerial ADU permit. The
state-law update worth knowing: AB 462 (effective October 2025),
reinforced by RPVMC § 17.10.050.H, confirms that
no public hearing is required for a CDP on an ADU.
That keeps a coastal ADU on the ministerial track rather than
opening it to a discretionary hearing. Properties outside the
Coastal Zone are unaffected by this layer entirely.
We map your parcel against the Coastal Zone boundary during the
Backyard Review, so you know up front whether a CDP is part of
your timeline — and so the coastal step never becomes a
surprise mid-permit.
How California state law overrides local rules
State law sets a floor every California city must meet under
Gov. Code § 66316. Rancho Palos Verdes’ ordinance is
largely aligned — its state-exemption section
(§ 17.10.040) deliberately tracks Gov. Code § 66323.
Four backstops are worth knowing where the local text reads more
narrowly or hasn’t caught up to a recent amendment:
Units per single-family lot (Gov. Code § 66323).
The headline § 17.10.020.B.1 says “one ADU and one
JADU.” State law — and the city’s own
§ 17.10.040 — require a conversion ADU, a JADU, and a
separate new detached ADU of up to 800 square feet to be allowed
together. The HCD ADU Handbook (March 2026, p. 17) confirms the
stack. Read narrowly, the local headline yields to state law.
JADU owner-occupancy narrowing (AB 1154).
AB 1154 (effective January 1, 2026) narrowed the JADU
owner-occupancy requirement at Gov. Code § 66333(b) to
JADUs that share sanitation facilities with the primary
dwelling. RPVMC § 17.10.030.A.2 still requires
owner-occupancy on every JADU, but state law preempts the
broader rule for a JADU with its own bathroom.
Multifamily detached ADU count (SB 1211).
SB 1211 (effective January 1, 2025) amended Gov. Code
§ 66323 to allow up to eight detached ADUs
on a lot with an existing multifamily dwelling — not to
exceed the number of existing units. RPVMC
§ 17.10.020.B.2 caps detached units at two, but state law
preempts the local cap on larger multifamily parcels.
The 800-square-foot floor (Gov. Code § 66321(b)(3)).
Local lot-coverage, floor-area-ratio, and open-space rules
cannot block an ADU of at least 800 square feet with 4-foot side
and rear setbacks. RPVMC § 17.10.020.A mirrors this, but
the state floor governs if the local text is ever read to
prevent it.
Permitting your Rancho Palos Verdes ADU
ADU and JADU applications in Rancho Palos Verdes are ministerial
— a site plan review approved by the director, no hearing,
no design-review board (RPVMC § 17.10.050.A–B and
Gov. Code § 66317). The city cannot deny a complying
application; it can only approve it or return a list of
deficiencies to fix.
The standard pathway
Applications go through the RPV Planning Division (30940 Hawthorne
Boulevard, (310) 544-5228). The city has 60 days from a complete
application to approve or deny it; miss the deadline and the
application is deemed approved by operation of law
(§ 17.10.050.B.3). SB 543 (effective January 1, 2026)
requires the city to determine completeness within 15 business
days. If a denial is issued, the city must give a full list of
what is deficient and how to remedy it (§ 17.10.050.B.1).
Fire and coastal review
Two Peninsula-specific steps can run alongside the ADU permit. The
Los Angeles County Fire Department reviews proposed setbacks for
fire safety (§ 17.10.050.F), and a parcel in the Coastal
Zone may need a Coastal Development Permit — with no public
hearing required (§ 17.10.050.H). In a Very High Fire Hazard
Severity Zone, plan review confirms the California Building Code
Chapter 7A wildfire-hardening measures. We surface each of these
during your Backyard Review so there are no surprises mid-cycle.
Concurrent and pre-approved plans
If the ADU application is submitted with a new primary-dwelling
application, the city may hold the ADU until the primary is acted
upon (§ 17.10.050.B). The city also offers pre-approved ADU
plans under Gov. Code § 65852.27 (§ 17.10.050.J), which
can shorten plan check. A new ADU may not be converted to primary
dwelling space for at least 20 years from construction
(§ 17.10.050.D).
Signature Homes that fit Rancho Palos Verdes lots
Three single-story Signature Homes built for the Peninsula's 16-18 ft detached-ADU envelope. Our two-story plans are detached-only and need roughly 25 ft of height to permit, so they sit out on Rancho Palos Verdes lots — we don't offer them as attached ADUs.
Four single-story and garage-conversion projects from our LA County portfolio — each one buildable inside the 16-18 ft detached cap that applies on a Rancho Palos Verdes lot.
The honest answer: it depends on what you build, where on the lot
it goes, and whether the parcel sits in a fire or coastal overlay.
After building ADUs across LA County, we can tell you exactly
where the money goes — and where most people lose it.
A custom-designed, detached new-construction ADU in a premium
coastal-hillside market like Rancho Palos Verdes typically runs
$400 to $600+ per square foot once you add architecture,
engineering, permitting, construction, finishes, and utility
connections. On a Peninsula lot, two factors push the high end:
hillside grading and foundation work, and the California Building
Code Chapter 7A wildfire-hardening package required on a Very High
Fire Hazard Severity Zone parcel.
CALI ADU Signature Homes are fixed-price from
$219,000 to $459,000,
all-inclusive — design, engineering, permits, construction,
interior finishes, appliances, and utility connections. The number
in your contract is the number you pay. No change orders, no
“unforeseen conditions” surcharges. Pricing is the
same whether the lot is in Rancho Palos Verdes, Torrance, or the
Valley — the model isn’t marked up for the coastal
ZIP code.
The Melrose
— 2 BR / 2 BA, 800 sqft, $329,000 all-inclusive.
A single-story plan at the 800-square-foot mark protected by
Gov. Code § 66321(b)(3), with a warm gable roof that reads
naturally on a Peninsula street.
Rancho Palos Verdes city fees
On top of construction, every ADU project carries city fees. State
and local law exempt the largest ones for smaller units: ADUs and
JADUs under 750 square feet pay no impact fees
(§ 17.10.020.G and Gov. Code § 66318). An ADU of 750
square feet or more pays impact fees proportional to the primary
dwelling’s square footage. Utility connection charges apply
only where the ADU is treated as a new connection — not when
it reuses the primary’s service. Your Backyard Review
includes a line-item estimate of these pass-through costs for your
specific lot.
Renting your ADU
A Rancho Palos Verdes ADU is a long-term rental asset. Per RPVMC
§ 17.10.020.C.13, an ADU or JADU may not be used as a
short-term rental — the ordinance cross-references the
city’s short-term-rental rules in § 17.02.026. State
law lets a city require a rental term of 30 days or longer
(Gov. Code § 66323(e) for ADUs; § 66333(g) for JADUs),
and RPV’s prohibition sits within that authority. Vacation,
weekly, and nightly rentals are off the table.
A well-built ADU on the Peninsula rents in a premium band —
typically $3,000 to $5,500+ per month depending on size, finish,
and view. A 1-bedroom Westwood (550 sqft) sits at the lower end; a
2-bedroom Melrose (800 sqft) in the middle; a 3-bedroom Lincoln
(1,000 sqft) at the top. Strong long-term demand from professional
families drawn to the Palos Verdes Peninsula Unified School
District keeps absorption steady.

the math for a specific Signature Home and your lot.
Why the Peninsula is a strong ADU market
Rancho Palos Verdes is a coastal-hillside city on the southern
Palos Verdes Peninsula, bordering Rolling Hills, Rolling Hills
Estates, and San Pedro. The lots are large by LA County standards,
the housing stock skews to ranch and Mediterranean homes from the
1960s through the 1980s, and many parcels carry ocean or
city-light views. That combination — big lots, high property
values, durable rental demand — makes for strong ADU
economics.
Demand is anchored by the Palos Verdes Peninsula Unified School
District, one of the highest-rated in the county, which pulls
long-term family tenants. Larger lots make it easier to site a
detached single-story ADU within the 16-18 ft cap while preserving
the primary home’s setbacks and the neighbors’ views.
The constraints — the Very High Fire Hazard Severity Zone
overlay and, on some parcels, the Coastal Zone — are real.
But they reward a builder who knows the rules cold: where the fire
code genuinely applies, where state law protects the ADU anyway,
and how to keep a coastal parcel on the ministerial track.
Rancho Palos Verdes ADU questions, answered
The questions Rancho Palos Verdes homeowners actually ask before
they start — with citations to RPVMC Chapter 17.10 and
Gov. Code §§ 66310–66342.
How many ADUs can I build on a Rancho Palos Verdes single-family lot?
More than the headline rule suggests. Per RPVMC
§ 17.10.020.B.1, the city’s headline language reads
“one ADU and one JADU” per single-family lot
— but that is the narrower of two pathways. RPVMC
§ 17.10.040 (state-exemption ADUs) and Gov. Code
§ 66323 require the city to allow a conversion ADU, a
JADU, and a separate new detached ADU of up to 800 square feet
to be combined on the same lot.
The HCD ADU Handbook (March 2026, p. 17) confirms the stack:
“local agencies must allow at least one ADU constructed
from existing space, one JADU, and one newly constructed
detached ADU.” Where the local headline is read more
narrowly, state law preempts it (Gov. Code § 66316).
Can I build an ADU in a Rancho Palos Verdes Very High Fire Hazard Severity Zone?
Yes. A Very High Fire Hazard Severity Zone (VHFHSZ)
designation does not block an ADU that state law protects. Per
RPVMC § 17.10.020.C.1, a VHFHSZ lot must meet the
wildfire-hardening standards in California Building Code
Chapter 7A (Title 24, Part 2) — ignition-resistant
materials, ember-resistant vents, and similar measures. These
rest on fire-code authority under Public Resources Code
§§ 4201–4204, so they survive the ADU
statute’s preemption rules.
What the city cannot do is use a fire-zone label to deny a
complying ADU or to demand sprinklers the statute exempts. Per
RPVMC § 17.10.020.C.14 and Gov. Code § 66314(d)(13),
an ADU needs sprinklers only if the primary residence already
requires them. RPV adopted Ordinance 691 in 2025 approving the
updated CalFire / OSFM zone map (effective January 1, 2026)
— confirm your specific lot’s current designation
before construction.
Does the Coastal Act apply to Rancho Palos Verdes ADUs?
On parts of the Peninsula, yes. Rancho Palos Verdes includes
land inside the California Coastal Zone, and per RPVMC
§ 17.10.050.H, nothing in the ADU ordinance supersedes the
California Coastal Act (Pub. Resources Code § 30000 et
seq.). A property inside the Coastal Zone may need a Coastal
Development Permit in addition to the ministerial ADU permit.
The key state-law update: AB 462 (effective October 2025) and
RPVMC § 17.10.050.H both confirm that no public hearing is
required for a Coastal Development Permit on an ADU. Properties
outside the Coastal Zone are unaffected. We check the boundary
against your parcel during the Backyard Review.
How tall can a detached ADU be in Rancho Palos Verdes?
Per RPVMC § 17.10.020.C.4.a, a detached ADU is capped at
16 feet, rising to 18 feet within one-half mile of a major
transit stop or high-quality transit corridor, or on a lot with
a multistory multifamily dwelling. An additional 2 feet is
allowed to match the primary dwelling’s roof pitch. These
caps mirror the state floor in Gov. Code § 66321(b)(4).
Because the detached cap sits at 16-18 feet, Rancho Palos
Verdes is a single-story detached-ADU market — our
single-story Signature Homes are designed for exactly this
envelope. An attached ADU may reach 25 feet (RPVMC
§ 17.10.020.C.4.b).
Is parking required for a Rancho Palos Verdes ADU?
Sometimes. Per RPVMC § 17.10.020.C.11, one space is
required, but the city must waive it under any of the five
state exemptions in Gov. Code § 66322: within one-half
mile of transit, inside a historically significant structure,
part of the existing primary residence, an on-street permit
area where the occupant isn’t offered a permit, or within
one block of a car-share.
When a garage is demolished or converted to build the ADU, no
replacement parking may be required (Gov. Code
§ 66314(d)(11)). A JADU never requires parking (Gov. Code
§ 66334(a)).
Does Rancho Palos Verdes require owner-occupancy for an ADU?
For a standard ADU, no — owner-occupancy may not be
required, consistent with state preemption under Gov. Code
§ 66315. For a JADU, RPVMC § 17.10.030.A.2 requires
the owner to live in the main house or the JADU.
But AB 1154 (effective January 1, 2026) narrowed the JADU
owner-occupancy mandate at Gov. Code § 66333(b) to JADUs
that share sanitation facilities with the primary dwelling. A
JADU with its own dedicated bathroom is no longer subject to
the requirement under state law, even though the RPV ordinance
has not yet been amended to reflect AB 1154.
Can I rent my Rancho Palos Verdes ADU on Airbnb?
No. Per RPVMC § 17.10.020.C.13, an ADU or JADU may not be
used as a short-term rental, cross-referenced to the
city’s short-term-rental rules in § 17.02.026. A
Rancho Palos Verdes ADU is a long-term tenancy asset only.
State law lets a city require a rental term of 30 days or longer
(Gov. Code § 66323(e) for ADUs; § 66333(g) for
JADUs), and RPV’s prohibition on short-term rental sits
within that authority.
Can a Rancho Palos Verdes ADU be sold separately from the main house?
Almost never. Per RPVMC § 17.10.020.C.12 and the recorded
covenant required by § 17.10.020.H, an ADU must remain
under the same ownership as the primary dwelling and may not be
sold separately. The single exception is the narrow nonprofit
pathway under Gov. Code § 66341 — an ADU built by a
qualified nonprofit corporation for a low- or moderate-income
buyer.
Rancho Palos Verdes has not adopted an AB 1033
condominium-conversion ordinance, so the broader separate-sale
pathway available in Santa Monica and Culver City does not
apply here (Gov. Code §§ 66341–66342).
