Convert the Garage to an ADU—or Keep Covered Parking and Pour a New Pad? Valley Hire Fork Under No-Replacement Rules

Quick answer

On a single-family Encino or San Fernando Valley lot in the City of Los Angeles, state ADU law generally does not require you to replace garage, carport, covered, or uncovered parking when that parking is demolished in conjunction with ADU construction or converted to an ADU (Government Code Section 66314(d)(11)). The California Department of Housing and Community Development (HCD) ADU Handbook (March 2026) and LADBS’s ADU page say the same thing in plain language: if you remove covered parking to build an ADU, you do not need to replace it. So the real hire fork is operational, not “will the City force me to rebuild the garage?”: convert the garage (reuse the structure, lose covered parking) versus keep the garage for parking and pour a new detached ADU pad elsewhere on the lot. Do not invent a parking-replacement crisis to sell one product. Pick the product that matches how you want to live and park — then hire one design-build team that can run that path through LADBS.

A garage conversion ADU keeps the existing garage structure and turns it into living space (often under conversion paths such as Government Code Section 66323(a)(1)). A new-pad detached ADU leaves the garage (or carport) in place for parking and builds a separate ADU on a new foundation elsewhere on the lot. Garage replacement is different: the detached garage comes down and a new ADU is built in its place — that path triggers simultaneous demo + ADU permit review under Section 66314(e); we cover that hire in a separate post (link below). No-replacement parking means the local agency shall not require the lost offstreet spaces to be rebuilt when the conversion or “in conjunction” demolition rules apply. Encino is in the City of Los Angeles — LADBS and City Planning, not Los Angeles County Building and Safety.

Key Takeaways

• Government Code Section 66314(d)(11): “When a garage, carport, covered parking structure, or uncovered parking space is demolished in conjunction with the construction of an accessory dwelling unit or converted to an accessory dwelling unit, the local agency shall not require that those offstreet parking spaces be replaced.”
• HCD ADU Handbook (March 2026), Parking Requirements: local agencies may not require replacement of off-street parking spaces when a garage, carport, covered parking structure, or uncovered parking space is demolished in conjunction with ADU construction or converted to an ADU.
• LADBS ADU page: “If you remove covered parking to build an ADU, you do not need to replace it.”
• ZA Memorandum No. 143 (City of Los Angeles) defines “in conjunction” for parking practice: the building permit application to remove covered parking and the ADU application are submitted at the same time, or one is submitted while the other application or permit is still open and valid.
• Hire fork A — convert: reuse the garage shell, accept loss of covered parking (no state-mandated replacement under 66314(d)(11)), plan for ADU (or JADU, if attached-garage rules fit) standards, utilities, and habitability.
• Hire fork B — keep garage + new pad: preserve covered parking, build a detached ADU on a new foundation; site setbacks, yard layout, and utility routing become the diligence — not a fake parking-replacement fee.
• Garage replacement (demo garage, build ADU in its place) is a third product and triggers Section 66314(e) simultaneous demo + ADU issuance. See the product-comparison section below for the one link to that companion hire post — this article does not duplicate that file.
• 121 has not published fees, case studies, license numbers, or owner quotes for convert-versus-new-pad ADUs in this article, and we will not invent them. This is a hire-decision guide tied to official sources.

What does “no replacement parking” actually mean for an Encino garage?

It means the City generally cannot force you to rebuild the parking spaces you lose when the garage (or carport, covered structure, or uncovered space) is converted to an ADU or demolished in conjunction with ADU construction.

Section 66314(d)(11) is the statute. HCD’s March 2026 handbook restates it. LADBS’s public ADU page restates it for Los Angeles applicants. ZA Memo 143 Q.13 explains how Los Angeles reads “in conjunction” for that parking rule: paired applications submitted together, or one filed while the other is still open and valid.

What it does not mean: that every Encino owner must convert the garage, that street parking will always feel fine, or that HOA / CC&R issues vanish. State ADU law limits local replacement mandates; it does not decide whether you personally want covered parking after the project. That preference is the hire fork.

Hire fork A: convert the garage to an ADU (lose covered parking, reuse the structure)

Conversion keeps the existing garage volume and turns it into independent living space. You typically gain schedule and structure reuse; you typically lose a weather-protected parking bay.

Operational diligence for Encino conversions:

• Confirm whether the product is a full ADU or, for some attached-garage situations, a junior ADU (JADU) path — different size, sanitation, and owner-occupancy rules.
• Confirm conversion versus expansion. Limited expansion for ingress/egress can apply under conversion statutes; a gut rebuild that is effectively new construction may not be the same file.
• Expect habitability work: insulation, waterproofing, openings, electrical, plumbing, and mechanical upgrades so the former garage meets dwelling standards.
• Treat parking as a lifestyle choice after 66314(d)(11): the City generally will not require replacement spaces, but you still need a driveway / street / tandem plan that works for your household.
• Do not confuse conversion with garage replacement. If the structure comes down and a new ADU goes up in its place, you are on the simultaneous demo + ADU path under Section 66314(e) — use the dedicated post linked above.

Hire signal: one team that owns conversion drawings, utility tie-ins, and the LADBS ADU (or JADU) path — not a “cheap garage remodel” package that ignores dwelling occupancy.

Hire fork B: keep the garage for parking and pour a new detached ADU pad

This path preserves covered parking and places a new ADU on a separate foundation. The trade is clear: you keep the garage bay, and you spend design effort on a second structure that must fit setbacks, height, utilities, and yard circulation.

Operational diligence for new-pad ADUs on Valley lots:

• Confirm a buildable envelope: four-foot side/rear setback baselines under state ADU law for many new detached ADUs, height limits, and any lot-specific overlays on ZIMAS.
• Route wet and dry utilities without trenching through the garage in a way that accidentally forces a conversion later.
• Protect driveway access so the kept garage remains usable after the ADU is occupied.
• Decide early whether the new ADU is a 66323 “state-mandated” detached unit (for example, the commonly discussed up-to-800-square-foot path with limited local standards) or a locally standardized ADU under Section 66314 — the hire and drawing set change with that choice.
• Do not invent a City requirement to demolish the garage. If you want covered parking, keeping the garage is a legitimate product under the same no-replacement statute that protects converters.

Hire signal: one design-build calendar for pad, framing, and ADU permit — not an architect who draws a cottage while a separate concrete crew pours a pad with no ADU ownership.

How do conversion, new-pad, and garage replacement differ as hire files?

Three products, three permit spines. Mixing the names is how Encino owners buy the wrong team.

• Conversion: structure stays; living space goes in; covered parking is usually lost; Section 66314(d)(11) bars required replacement of those spaces when converted to an ADU.
• Keep garage + new pad: garage stays for parking; new detached ADU elsewhere; parking replacement is not the issue — siting and utilities are.
• Replacement: detached garage demolished and ADU built in its place; Section 66314(e) requires the demolition permit to be reviewed with the ADU application and issued at the same time; Section 66314(d)(11) still addresses parking when demo is in conjunction with ADU construction.

If the owner has not chosen among convert / keep-and-pad / replace, stop schematic. The contractor scope and the LADBS file change with that choice.

What does ZA Memo 143’s “in conjunction” language mean for parking — and what it does not mean?

For Los Angeles parking practice, ZA Memo 143 Q.13 treats “in conjunction” as simultaneous submittal of the removal application and the ADU application, or filing one while the other application or permit remains open and valid.

That definition supports coordinated files when parking is removed as part of an ADU project. It is not a license to demolish a garage months ahead of an undefined ADU. It also does not force conversion: if you keep the garage and pour a new pad, you are not relying on the parking-replacement bar for a demolished bay — you are simply not demolishing that bay.

Hire lesson: ask any salesperson who says “we have to knock the garage first or the City will make you rebuild parking” to open Section 66314(d)(11), the HCD handbook parking section, and ZA Memo 143 Q.13. Then decide convert versus keep-and-pad on lifestyle, not fear.

Design-build versus architect-now, contractor-later for this hire fork

Hire the team that will force the convert-versus-pad decision onto paper before anyone prices framing or a slab.

Architect-now / contractor-later is how Valley owners get a pretty ADU plan that assumes the garage remains parking — then meet a GC who discovers the drawings actually convert the garage, or the reverse. Split handoffs also bury “in conjunction” coordination when any parking removal is part of the ADU file.

A design-build hire gate for Encino looks like this:

• Write convert / keep-garage-new-pad / replace on the first page of the proposal.
• If convert: lock ADU vs JADU product, habitability scope, and the fact that covered parking goes away under 66314(d)(11)’s no-replacement rule — not under a City “rebuild garage” mandate.
• If keep-and-pad: lock setbacks, height, driveway clearance, and utility routing with the garage staying.
• If replace: stop and use the simultaneous demo + ADU hire path under Section 66314(e) (linked post).
• Refuse a retainer that prices “ADU somewhere” without naming which of the three products you are buying.

How can 121 Design Build help Encino owners choose convert versus new pad?

121 Design Build is an Encino design-build firm. We will not take a retainer to “solve parking replacement” that state ADU law already generally prohibits under Section 66314(d)(11), and we will not push a garage conversion merely because a sales script says covered parking is worthless. For an owner on a Ventura Boulevard–corridor, south-of-the-Boulevard, or Valley single-family lot choosing between converting the garage and keeping it while pouring a new ADU pad, our ADU & JADU service is the direct fit: one file that ties lifestyle (covered parking yes/no), site fit, and the LADBS path to the statute that actually governs replacement parking.

We have not published fees, case studies, license numbers, or owner quotes for this fork, and we will not invent them. What we will do is put the live hire questions next to the lot: Do you want to keep covered parking? Is the garage detached or attached? Is this conversion, new-pad, or replacement? Who owns the LADBS submittal so any parking removal stays “in conjunction” under ZA Memo 143 if demo is part of the ADU? Ask those before anyone schedules a pour or a gut.

Frequently Asked Questions

If I convert my Encino garage to an ADU, must I replace the parking?

Generally no. Government Code Section 66314(d)(11) says the local agency shall not require replacement of those offstreet parking spaces when a garage is converted to an ADU. HCD’s March 2026 handbook and LADBS’s ADU page align with that rule. Confirm the path for your address with LADBS.

Can I keep my garage for parking and still build a detached ADU?

Yes — that is the keep-garage + new-pad hire fork. State no-replacement rules do not force you to convert. Site setbacks, height, utilities, and driveway clearance become the diligence.

Is converting the garage the same as replacing it with a new ADU?

No. Conversion keeps the structure. Replacement demolishes a detached garage and builds a new ADU in its place, which triggers Section 66314(e) simultaneous demo + ADU issuance. See the product-comparison section above and the companion Sources link for that hire — this post does not duplicate it.

What does “in conjunction” mean for parking in Los Angeles?

ZA Memo 143 Q.13: the removal application and the ADU application are submitted at the same time, or one is submitted while the other application or permit is still open and valid. Coordination matters; demolish-first / invent-ADU-later does not.

Does LADBS require replacement parking when covered parking is removed for an ADU?

LADBS’s ADU page states that if you remove covered parking to build an ADU, you do not need to replace it — consistent with Section 66314(d)(11).

Should I hire based on fear that the City will make me rebuild a garage?

No. Hire based on whether you want covered parking after the project. The statute generally bars required replacement when conversion or in-conjunction demolition rules apply; it does not decide your lifestyle preference.

Is Encino under Los Angeles County for this convert-versus-pad file?

No. Encino is in the City of Los Angeles. File with LADBS and City Planning. County Building and Safety / EPIC-LA is the wrong window.

Has 121 published fees or case studies for convert-versus-new-pad ADUs?

No. This article does not invent fees, case studies, license numbers, or owner quotes.

Is this legal advice?

No. This article is general information from a design-build and permitting perspective. Confirm live Government Code Section 66314, the HCD ADU Handbook, ZA Memorandum No. 143, and the lot’s overlays with LADBS, City Planning, and, if needed, your own attorney.
