Building an ADU in Inglewood. Rules, costs, timeline.
What Inglewood's 2023 ordinance (IMC § 12-149) allows, where state law now overrides it after HCD's 2025 review, and what an all-in build costs on an Inglewood lot in 2026.
What you can build — at a glance
Max ADU size
Detached up to 1,000 sq ft (IMC § 12-149); state law guarantees at least an 800 sq ft unit with 4-ft setbacks regardless of local caps (Gov. Code § 66321(b)(3); § 66323)
Detached height
16 ft base, 18 ft within ½ mile of transit or with a multistory primary, plus 2 ft for a matching roof pitch (Gov. Code § 66321(b)(4)). The one-story / 16-ft cap in IMC § 12-149 is preempted above 16 ft (HCD letter 5/12/2025)
Attached height
Up to 25 ft and two stories (Gov. Code § 66321(b)(4)(D))
Side & rear setbacks
4 ft (Gov. Code § 66314(d)(7); § 66323)
Units per SFR lot
1 ADU + 1 JADU, plus the § 66323 combinations (one converted ADU + one detached ADU + one JADU) (Gov. Code § 66323). Local IMC § 12-149 caps at 1 ADU + 1 JADU — state law preempts (HCD letter 5/12/2025)
Parking required
1 space, removed by any of the six Gov. Code § 66322 exemptions — transit, historic district, conversion, permit-area, car-share, or new-build (Gov. Code § 66322; IMC § 12-43(I))
Permit timeline
60 days · ministerial approve-or-deny, no hearing (Gov. Code § 66317; § 66315)

Per IMC § 12-149 et seq. (Ord. No. 24-02) and Gov. Code §§ 66310–66342, cross-checked against HCD’s May 12, 2025 ordinance-review letter to the City of Inglewood. Full citations in the sections below.
An ADU in Inglewood answers to two sets of rules at once. The city
has its own ADU ordinance, codified in Chapter 12 of the Inglewood
Municipal Code and adopted as Ordinance No. 24-02 in December 2023.
On top of that sits California state ADU law, Gov. Code
§§ 66310–66342, which applies in every city in the
state.
When the two disagree, state law wins (Gov. Code § 66316). That
matters more in Inglewood than in most cities, because the state
housing agency has already reviewed the local ordinance and found it
wanting. We read both the ordinance and the state statute, and we
tell you which one actually governs each rule.
State law. California Government Code
§§ 66310–66342. Sets statewide minimums for size,
height, setbacks, parking, and the 60-day ministerial timeline that
no city — Inglewood included — can undercut.
Local ordinance. Inglewood Municipal Code
§ 12-149 and the surrounding Chapter 12 sections (Ord. No.
24-02). Spells out the city’s size caps, setbacks, parking,
and covenant rules — several of which are now preempted.
HCD commentary. The California Department of
Housing and Community Development’s May 12, 2025 letter to
Inglewood lists sixteen ways Ord. No. 24-02 does not comply with
state law. It is the clearest available guide to where local text
yields to the statute.
What you can build on your lot
Everything in this section is grounded in Inglewood Municipal Code
§ 12-149 and the surrounding Chapter 12 sections, with
state-law citations called out where Gov. Code §§ 66310–66342
supplement or override the local rule. We won’t re-cite the
local section on every line — assume IMC § 12-149 under
each subsection unless we say otherwise.
Size limits
The ordinance caps a detached ADU at 1,000 square feet, and caps an
attached ADU at 850 square feet or 50% of the main house, whichever
is smaller. State law sets a floor underneath those caps that the
city cannot cross: every homeowner must be allowed at least an
800-square-foot ADU with 4-foot side and rear setbacks (Gov. Code
§ 66321(b)(3)), and an 800-square-foot detached unit is buildable
by right (Gov. Code § 66323). A unit converted from existing
house or garage space carries no size cap at all. HCD’s 2025
letter directed Inglewood to write these exceptions into its text;
until it does, the state floor controls.
Setbacks
Side and rear setbacks are 4 feet — the statewide floor in Gov.
Code § 66314(d)(7), which a § 66323 unit locks in. The
ordinance keeps a deep front-yard requirement tied to lot depth, but
Gov. Code § 66321(b)(3) bars the city from using a front-setback
rule to block an 800-square-foot ADU. On a typical Inglewood lot, the
ADU sits in the rear yard well clear of the front.
The Sunset
— 480 square feet, one bedroom, single story. Sits comfortably
inside Inglewood’s rear-yard setbacks and stays under the 750-square-foot
line where impact fees fall away (Gov. Code § 66318).
Maximum height
A detached ADU follows the state height floor in Gov. Code
§ 66321(b)(4): 16 feet by default, 18 feet on a lot within a
half-mile of a transit stop or with a multistory primary home, plus
2 feet to match the main house’s roof pitch. The ordinance
limits detached ADUs to one story and 16 feet, but HCD found the
one-story restriction impermissible — the statute sets no story
cap. An attached ADU can reach 25 feet and two stories (Gov. Code
§ 66321(b)(4)(D)). With Metro K Line service through the city,
many Inglewood lots qualify for the 18-foot bonus.
Parking
The ordinance asks for one parking space (IMC § 12-43(I)), but
Gov. Code § 66322 removes that requirement under any of six
conditions:
The lot is within a half-mile of a transit stop.
The ADU is in an architecturally or historically significant historic district.
The ADU is part of an existing primary residence or accessory structure.
On-street parking permits are required but not offered to the tenant.
A car-share vehicle is located within one block.
The ADU is part of a new single-family or multifamily home build.
HCD’s letter found Inglewood listed only two of the six and must
add the rest. A converted garage never triggers replacement parking
for the main house (Gov. Code § 66314(d)(11)).
Lot coverage and FAR
Inglewood’s base-zone lot-coverage and floor-area rules still
apply to the property as a whole, but they cannot be used to deny a
standard ADU. Gov. Code § 66321(b)(3) protects the
800-square-foot unit against lot-coverage, floor-area-ratio, and
open-space limits. In plain terms: a coverage rule can shape where
the ADU goes, not whether you get one.
The Westwood
— 550 square feet with a real living room. A single-story
one-bedroom that clears Inglewood’s height floor and reads as
a full apartment to a long-term tenant.
Owner-occupancy
You do not have to live on the property to have an ADU. Gov. Code
§ 66315 bars any owner-occupancy requirement on an ADU, and
HCD’s letter told Inglewood that even its recorded-covenant
requirement for ADUs is an impermissible extra standard. A junior ADU
is different: owner-occupancy still applies, but AB 1154 (effective
January 1, 2026) narrowed Gov. Code § 66333 so the rule reaches
only a JADU that shares a bathroom with the main house. Give the JADU
its own bathroom and the mandate falls away.
Impact fees
An ADU under 750 square feet pays no impact fees (Gov. Code
§ 66318). At 750 square feet or more, any fee must be charged in
proportion to the size of the main house — not as a flat
per-unit charge. That single line is why the Sunset, at 480 square
feet, is the lineup’s most fee-efficient rental on an Inglewood
lot.
Permitting timeline
ADU review is ministerial: the city must approve or deny a complete
application within 60 days, with no public hearing (Gov. Code
§ 66317; § 66315). HCD’s letter even flagged the
ordinance’s “shall act” wording and the
discretionary “site plan review” it referenced, both of
which give way to the ministerial standard. SB 543 (effective January
1, 2026) tightened the completeness-review clock that starts that
60-day count.
Where Inglewood’s ordinance falls behind state law
Most cities’ ADU ordinances drift out of date as the
Legislature amends the statute year after year. Inglewood’s is
a documented case. On May 12, 2025, HCD reviewed Ordinance No. 24-02
and issued sixteen findings of noncompliance with State ADU Law. You
do not have to take our word for which local rules no longer hold
— the state housing agency wrote them down.
The findings that matter most to an Inglewood homeowner:
The one-story / 16-ft cap. IMC § 12-149
limits a detached ADU to one story; HCD found the story limit
impermissible. Height still follows the Gov. Code
§ 66321(b)(4) floor (16/18/20 ft), but the city cannot bar a
second story outright.
The 500-square-foot minimum. The ordinance set a
500-square-foot minimum ADU; HCD noted that state law recognizes
efficiency units as small as 150 square feet (Gov. Code
§ 66313; Health & Safety Code § 17958.1).
Percentage-of-primary size caps. Tying ADU size to
a share of the main house cannot be used to block the
800-square-foot unit protected by Gov. Code § 66321(b)(3).
Missing parking exemptions. The ordinance listed
two of the six Gov. Code § 66322 exemptions; the other four
apply by force of state law anyway.
The ADU covenant. Requiring a recorded covenant as
a condition of an ADU permit is an impermissible extra standard
under Gov. Code § 66315.
Multifamily ADUs. The ordinance never added the SB
1211 allowances — up to eight detached ADUs on a lot with an
existing multifamily building, capped at the number of existing
units (Gov. Code § 66323).
The takeaway is not that Inglewood blocks ADUs — it is that the
local text reads more restrictively than the law allows. We design to
the statute, so the plan that lands on the city’s desk is the
one the city is required to approve.
How California state law overrides Inglewood
State law preempts a more restrictive local rule (Gov. Code
§ 66316). In Inglewood, that is not a theoretical point —
HCD has already identified the conflicts. These three carry the most
weight for a homeowner planning a build.
Owner-occupancy and covenants — Gov. Code
§ 66315 bars an owner-occupancy requirement on an ADU, and HCD
found Inglewood’s ADU covenant requirement impermissible.
Your right to build does not depend on living on the lot.
Height and stories — Gov. Code
§ 66321(b)(4) guarantees 16 to 20 feet for a detached unit
depending on transit proximity and roof pitch, and the city cannot
impose a one-story cap. The ordinance’s single-story limit is
preempted.
Parking — all six Gov. Code § 66322
exemptions apply in Inglewood even though the ordinance lists only
two, and a converted garage never owes replacement parking (Gov.
Code § 66314(d)(11)).
Permitting your ADU, step by step
Inglewood reviews ADUs through its Development Services Department on
a ministerial track: no hearing, no neighbor sign-off, a yes-or-no
decision against fixed standards within 60 days of a complete
application (Gov. Code § 66317). Here is how a CALI ADU project
moves through it.
Lot check and plan selection. We confirm your
zoning, setbacks, and transit distance, then match a Signature Home
to the buildable area — usually two to three weeks.
Plan set and submittal. We prepare the site plan,
floor plan, and elevations and submit to Development Services with
the structural and energy documents the Building Division needs.
Ministerial review. The city checks the plans
against the standards and must approve or deny within 60 days. We
design to the state floor so there is nothing discretionary to
argue about.
Construction. Once permitted, construction runs on
a fixed-price, guaranteed-timeline contract — roughly six to
nine months depending on the model.
Signature Homes that fit Inglewood lots
Inglewood's detached envelope is a single-story envelope, so these three picks all come from the one-story collection — sized for the city's investor-heavy, transit-rich rental market, from a fee-exempt studio to a family-sized flagship.
Single-story builds and garage conversions from the surrounding South LA and Westside markets — the closest analogs to a typical Inglewood rental-investor project.
A CALI ADU Signature Home is fixed-price. The number you sign is the
number you pay — nine models from $219K
to $459K, all-in, with the design, the
engineering, and the construction in one contract. No allowances that
balloon, no change-order surprises mid-build.
Inglewood’s fee picture is favorable for the smaller models.
A unit under 750 square feet pays no impact fees (Gov. Code
§ 66318), so a Sunset or a Wilshire avoids the per-unit charges
that push up the cost of a larger build. School and utility fees
still apply, and they scale with size.
The Laurel Canyon
— a 660-square-foot two-bedroom at a fixed $289,000. Two
bedrooms clear the rent of any one-bedroom in the lineup, which
matters in a city where tenants compete for space near SoFi and the
K Line.
Put the fixed price next to the fee structure and the math is clean:
on an Inglewood lot, the all-in cost is the contract price plus a
modest, size-scaled set of city fees — no impact fees at all
under 750 square feet. Our calculator breaks it down lot by lot.
Renting an ADU near SoFi and the K Line
Inglewood ADUs rent on long-term leases — 30 days or more.
Short-term rental is not allowed (IMC § 12-148), and state law
backs the city’s right to require a 30-day floor (Gov. Code
§ 66315). For most owners that is the better business anyway: a
steady year-round tenant beats the turnover of a vacation listing.
Demand is the story here. Inglewood sits at the center of a sports
and entertainment district — SoFi Stadium, the Intuit Dome, the
Kia Forum — minutes from LAX and on the Metro K Line. That mix
of jobs, transit, and event traffic keeps a deep pool of long-term
renters looking for well-built private units. A one-bedroom Sunset or
a two-bedroom Laurel Canyon in an Inglewood backyard rents quickly and
holds its tenant.
Why Inglewood is a strong ADU market
Inglewood has changed faster than almost any city in Los Angeles
County. The arrival of SoFi Stadium, the Intuit Dome, and the Metro K
Line has pulled new investment and new residents into a city of
established single-family neighborhoods. Property values have climbed,
and with them the value of a second unit in the backyard —
whether you rent it, house family in it, or hold it as long-term
equity.
The regulatory picture cuts in the homeowner’s favor, too. Where
Inglewood’s ordinance reaches past what the law allows, state
law pulls it back — HCD has already mapped exactly where. Build
to the statute and the city’s most restrictive provisions
simply do not bind you. That is a strong position to build from.
Inglewood ADU questions, answered
The questions Inglewood homeowners actually ask before they start
— with citations to IMC § 12-149, the city’s ADU
standards, and Gov. Code §§ 66310–66342.
How big an ADU can I build in Inglewood?
Per IMC § 12-149, a detached ADU is capped at 1,000 square
feet. State law sets the floor the city can’t go below:
you must be allowed at least an 800-square-foot ADU with 4-foot
setbacks (Gov. Code § 66321(b)(3)), and an 800-square-foot
detached unit is buildable by right (Gov. Code § 66323). A
unit converted from existing space has no size cap. HCD’s
2025 letter directed Inglewood to add these exceptions.
Can I build a two-story ADU in Inglewood?
Per Gov. Code § 66321(b)(4), a detached ADU gets 16 feet by
default, 18 feet near transit or with a multistory primary, plus
2 feet for a matching roof pitch. Inglewood’s one-story cap
at IMC § 12-149 was found impermissible by HCD — the
statute has no story limit. An attached ADU can reach 25 feet and
two stories (Gov. Code § 66321(b)(4)(D)). In practice, our
single-story Signature Homes fit Inglewood’s detached
envelope best.
Do I need to add parking for an ADU in Inglewood?
Per IMC § 12-43(I) the city asks for one space, but Gov. Code
§ 66322 removes it under six conditions — transit
within a half-mile, historic district, conversion of an existing
structure, on-street permit area, car-share nearby, or a new-home
build. HCD found Inglewood listed only two and must honor all six.
A converted garage owes no replacement parking (Gov. Code
§ 66314(d)(11)). With K Line stations in the city, many lots
qualify for the transit exemption.
Does Inglewood require me to live on the property?
Not for an ADU. Gov. Code § 66315 bars an owner-occupancy
requirement on ADUs, and HCD found even Inglewood’s recorded
covenant for ADUs impermissible. A junior ADU still carries
owner-occupancy, but AB 1154 (effective January 1, 2026) narrowed
Gov. Code § 66333 so it applies only when the JADU shares a
bathroom with the main house.
Can I use my Inglewood ADU as a short-term rental?
No. Per the City of Inglewood ADU Development Standards and IMC
§ 12-148, ADUs and JADUs must be rented for 30 days or more
and may not be used as short-term rentals. State law allows the
city to set that 30-day floor (Gov. Code § 66315). A
long-term lease is the lawful path to rental income.
Is Inglewood’s ADU ordinance up to date with state law?
Not fully. Per HCD’s May 12, 2025 review letter, Ordinance
No. 24-02 does not comply with State ADU Law on sixteen points
— outdated statute numbering, missing parking exemptions, the
one-story cap, percentage-of-primary size limits, the ADU
covenant, and missing SB 1211 multifamily allowances among them.
Where the ordinance and Gov. Code §§ 66310–66342
conflict, state law controls.
Can I sell my Inglewood ADU separately from the house?
Generally no. Separate sale is allowed only where a city opts in
under AB 1033 (Gov. Code § 66341/§ 66342), and Inglewood
has not. The narrow exception is a sale to or through a qualified
nonprofit under Gov. Code § 66341, which HCD directed
Inglewood to recognize. For nearly all owners, the ADU stays part
of the property.
