Louisiana HOA ADUs & Modifications

Key Findings

Louisiana runs on civil law, and that changes how a homeowners association reviews what a member wants to build. The state does not lean on common-law covenants. It leans on recorded building restrictions, on two newer statutes that sit on top of them, and on a short list of federal rules. Here is what that means, point by point.

• Building restrictions are the operative institution. Civil Code article 775 defines a building restriction as a charge that the owner of an immovable imposes under a general plan governing building standards, permitted uses, and improvements. In the civil law, these do the work that covenants do everywhere else.¹
• Article 783 sets a supersession rule and an interpretation rule. When doubt arises about whether a building restriction exists, whether it is valid, or how far it reaches, the law resolves that doubt in favor of unrestricted use. And in a conflict, the Condominium Act, the Timesharing Act, and the Planned Community Act override the Civil Code building-restriction articles.²
• Solar is protected under a reasonableness standard. R.S. 9:1255 bars unreasonable restriction of solar collectors, but it preserves approval requirements written into building restrictions and it exempts historic districts, historical preservations, and landmarks.³
• ADUs are a two-layer question. Parish or municipal zoning sets one layer, and the building restrictions and declaration set the other, with the building restrictions binding inside the community. Louisiana enacts no ADU preemption, which sets it apart from California and Colorado.^4,5,6
• A 2025 appellate decision confirms the framework. In Marina Homeowners Association, Inc. v. Cahill, the Second Circuit upheld enforcement of a residential-use building restriction against a short-term rental.⁷

The legal framework

Building restrictions and the planned-community statute

Louisiana does not use common-law covenants that run with the land. The working concept here is the building restriction. Article 775 of the Civil Code defines it as a charge that an owner imposes on an immovable under a general plan governing building standards, specified uses, and improvements, and the plan has to be feasible and capable of being preserved.¹ Article 777 treats these restrictions as incorporeal immovables and real rights, close cousins of predial servitudes.⁸ Article 783 then supplies two rules that drive architectural review. First, when doubt arises about whether a restriction exists, whether it is valid, or how far it extends, the law resolves that doubt in favor of unrestricted use. Second, in a conflict, the Condominium Act, the Timesharing Act, and the Planned Community Act supersede the Civil Code building-restriction articles. The 2025 rework updated article 783 to point at the Planned Community Act instead of the old Homeowners Association Act.²

The Louisiana Planned Community Act runs from R.S. 9:1141.1 through 1141.50. The Senate Bill 23 digest says as much: the proposed law "creates the Louisiana Planned Community Act modeled after" the Uniform Common Interest Ownership Act.⁹ Lawmakers enacted it as Acts 2024, No. 158. It took effect January 1, 2025 and expanded the old nine-section Homeowners Association Act.¹⁰ Its applicability section, R.S. 9:1141.3, does not force existing associations to fall in line. The Act does not disturb the validity or superiority of any community-document provision filed for registry before the effective date, it applies only where the community documents stay silent, and it does not require an association that existed before the effective date to change its structure, its documents, or the way it amends documents or calculates assessments.¹¹ Residential condominiums stay under the Louisiana Condominium Act, R.S. 9:1121.101 and following, a separate and older regime; section 9:1121.106 says zoning and land-use law may not prohibit the condominium form of ownership.¹² Cooperatives sit under their own statute, R.S. 12:499.1 and following.

The rules for changing a building restriction stand out. Under R.S. 9:1141.6, an association establishes, amends, or terminates restrictions the way the applicable community document directs. Where the document says nothing, default owner-vote thresholds take over. Owners can establish a building restriction by agreement of three-fourths of the lot owners, make it more onerous or increase it by two-thirds, and make it less onerous, reduce it, or terminate it by more than one-half.¹³ Those thresholds follow the historic Civil Code approach, and the planned-community statute now carries them forward.

Solar and other categories

Solar is the anchor protection. R.S. 9:1255 says no person or entity may unreasonably restrict a property owner's right to install or use a solar collector, which the statute defines as any device, or combination of elements, that relies on sunlight as an energy source. This is a reasonableness standard, not a flat ban. Subsection C keeps in place any zoning restriction, servitude, or building restriction that requires approval before installation, so an association may still impose reasonable approval and placement conditions. Subsection D carves out property that a historic-preservation district commission, a landmarks commission, or a planning or zoning commission has identified as a historic district, a historical preservation, or a landmark.³ The upshot: an association may not ban solar outright, but it may apply reasonable design and placement review, and the protection does not reach historically designated property. The current text still reflects Acts 2010, No. 274, with no HOA-directed change in 2024 or 2025.³

On electric-vehicle charging, Louisiana has no HOA-specific statute at all. California, Florida, Colorado, and Washington have passed right-to-charge laws that limit what an association can do about charging stations. Louisiana has not, so the building restrictions and the declaration govern any EV installation.¹⁴ The pattern repeats for landscaping, including drought-tolerant, native, and water-conservation landscaping, and for flag display. No state HOA statute speaks to them, so the building restrictions and the declaration control. The practical effect is straightforward: outside solar, the building restrictions and the declaration decide what a member may change, checked only by the federal overlays described below.

ADUs and federal overlays

Louisiana has no statewide statute that voids building restrictions or declarations for accessory dwelling units. ADUs turn on a two-layer analysis. Start with the locality. Parish or municipal zoning decides what the area allows. New Orleans, for instance, regulates accessory structures through Article 21 of its Comprehensive Zoning Ordinance, and because Louisiana operates under home rule, the allowances shift from one parish or municipality to the next.⁴ Then turn to the community. The building restrictions and the declaration decide what the association allows. Where the two clash, the building restrictions win inside the community. A parish permit does not override a recorded residential-use restriction. That is the mirror image of states that strip HOAs of authority over ADUs. California Civil Code § 4751(a) makes any governing-document provision that "either effectively prohibits or unreasonably restricts the construction or use of an accessory dwelling unit or junior accessory dwelling unit on a lot zoned for single-family residential use . . . void and unenforceable."⁵ Colorado's HB 24-1152, signed May 13, 2024 and effective June 30, 2025, makes any association ban on ADUs, or any restrictive design or dimension standard, void as a matter of public policy in a supportive jurisdiction.⁶ Louisiana enacts no comparable preemption.

Four federal overlays bind every Louisiana association no matter what the state framework says, and none of them is Louisiana law. The Freedom to Display the American Flag Act of 2005 protects a member's display of the United States flag, subject to reasonable restrictions.¹⁵ The FCC's OTARD rule, 47 C.F.R. § 1.4000, limits what an association can do about antennas and satellite dishes within a member's exclusive-use area.¹⁶ The Fair Housing Act, 42 U.S.C. § 3604(f)(3), requires an association to permit reasonable modifications for disability, usually at the resident's expense.¹⁷ And ADA Title III reaches common-area facilities that count as places of public accommodation.¹⁸

Compliance obligations created by the framework

A. Architectural review process obligations

Review authority comes from the building restrictions and the declaration, layered with the Planned Community Act or, for condominiums, the Condominium Act. This applies to both kinds of community.¹³ An architectural committee or a board has to act within the authority the community documents actually grant, because article 783 resolves any doubt about the reach of a restriction in favor of unrestricted use.² Written decisions and recordkeeping follow from the declaration and, for planned communities, from the records and procedural provisions of the Planned Community Act; condominiums follow the Condominium Act on the same points.¹⁰

B. Modifications the association must permit

Put it positively, and here is what an association has to allow. It may not unreasonably restrict solar collectors under R.S. 9:1255, a reasonableness standard rather than an absolute bar, and one that does not reach historic districts, historical preservations, or landmarks.³ It must permit display of the United States flag, subject to reasonable restrictions, under the 2005 federal Act.¹⁵ It must allow antennas and satellite dishes within a member's exclusive-use area under the OTARD rule.¹⁶ It must permit reasonable modifications for disability at the resident's expense under the Fair Housing Act.¹⁷ And where common-area facilities amount to public accommodations, they have to meet ADA Title III accessibility requirements.¹⁸ The first of these rests on Louisiana statute; the rest are federal, and they apply to planned communities and condominiums alike.

C. ADU obligations and limits on HOA authority

No statute in Louisiana requires an association to permit an ADU against its own building restrictions.¹ Parish or municipal zoning binds the locality, not the association, so a zoning allowance, standing alone, does not force the association to approve an ADU.⁴ Inside the community, the building restrictions and the declaration decide whether an ADU goes forward.²

D. Enforcement, dispute resolution, and appeal obligations

An association enforces its building restrictions and community documents through the courts, and the community documents usually vest the right to enforce in the association or in an owner.¹⁰ A planned-community association holds a homeowners association privilege for unpaid assessments under R.S. 9:1141.9, and a condominium association holds a privilege under the Condominium Act.¹⁹ Before it enforces, the association has to follow any pre-suit demand, notice, or procedure that the declaration or the Planned Community Act requires.¹⁰ Disputes start in the Louisiana District Courts, move on appeal to the Louisiana Courts of Appeal across five circuits, and reach the Louisiana Supreme Court only on discretionary review.⁷

Recent legislative and judicial activity

A. Recent bills

Louisiana did not run a flurry of HOA bills. It made one structural change and built around it.

We found no separate 2024 or 2025 bill that amended the solar statute, R.S. 9:1255, or that changed the Condominium Act on architectural review. The current text of R.S. 9:1255 still traces to Acts 2010, No. 274.³

B. Recent appellate rulings

Louisiana's appellate courts are not remaking HOA law from the bench. One recent decision shows how the building-restriction framework works when an association enforces it.

A second decision runs alongside it. In Childers v. Laurel Lakes Estates Homeowners' Ass'n, Inc., 2022-0936 (La. App. 1 Cir. 5/24/23), 368 So. 3d 1123, a First Circuit subdivision dispute, the court held that a later buyer takes the property bound by recorded building restrictions. Marina leaned on Childers for exactly that point.⁷

C. Active legislative debates

In 2025, the debate over Louisiana community-association law centered on putting the Planned Community Act into practice, not on any new preemption of ADUs or modifications. We identified no ADU-preemption bill that would reach building restrictions. The year's solar activity focused on siting and permitting large-scale solar generation facilities, through Act 279 of 2025, and left the HOA solar protection in R.S. 9:1255 untouched.²⁰

Recommendations

1. Classify each community by formation date first. For any Louisiana community, find out whether the declaration was recorded before January 1, 2025. If it was, treat the existing declaration and bylaws as superior and use the Planned Community Act only to fill gaps where the documents stay silent, under R.S. 9:1141.3. If the community formed on or after that date, build its governance to the Act. The one thing that changes this step is a recorded amendment that opts an older community into the Act.
2. Run architectural review off the recorded building restrictions, not covenant analogies. Frame every denial and approval in terms of the building restrictions and the declaration, and keep article 783 in mind: doubt about the reach of a restriction goes to unrestricted use. Write decisions that cite the specific declaration article you are invoking.
3. Treat solar as approvable with conditions, never bannable. Under R.S. 9:1255, apply reasonable design and placement conditions and process solar applications on that footing. Only in a designated historic district, historical preservation, or landmark does the protection step aside. What would change this posture is an amendment to R.S. 9:1255 or a Louisiana appellate decision defining "unreasonable."
4. Analyze ADUs in two layers, then enforce the building restriction. Confirm what parish or municipal zoning permits, for example New Orleans CZO Article 21, then confirm what the building restrictions and declaration permit. Where a residential-use or single-family restriction exists, it controls inside the community regardless of a local permit, as Marina v. Cahill confirms for short-term rentals. Revisit this only if Louisiana ever enacts an ADU-preemption statute. None exists today.
5. Apply the four federal overlays as a compliance floor. Permit U.S. flag display, OTARD antennas, FHA reasonable modifications, and ADA common-area access regardless of the declaration, and label them in board communications as federal requirements, not Louisiana ones.
6. Do not describe Louisiana as licensing community association managers. The state has no dedicated HOA regulator and no CAM licensing program. Route disputes through District Court, then the Court of Appeal for the relevant circuit, then discretionary Supreme Court review.

Caveats

• Effective-date nuance. Acts 2024, No. 158 took effect January 1, 2025. The bill digest describes application to newly formed communities from that date and to existing planned communities from January 1, 2026, subject to exceptions that preserve documents already in place. The statutory applicability text, R.S. 9:1141.3, stresses that pre-existing community documents keep their superiority and that the Act reaches existing communities only where their documents stay silent. Read the two together, and confirm the current text before you rely on either date.^9,11
• Uniform-act model. The digest and the enacting materials describe the Act as modeled on the Uniform Common Interest Ownership Act. Louisiana remains a civil-law jurisdiction that layers the Planned Community Act and the Condominium Act on top of the Civil Code. The uniform-act model shapes the statute's structure, but it does not turn Louisiana into a conventional UCIOA state.⁹
• Solar statute currency. The verified legis.la.gov text of R.S. 9:1255 carries only the Acts 2010, No. 274 source note. A separate 2025 solar act, Act 279, addresses permitting for large-scale generation facilities, not the HOA solar protection. Do not conflate the two.^3,20
• Case scope. Marina v. Cahill is a short-term rental dispute decided on residential-use building restrictions. It illustrates the building-restriction framework and the liberal-construction rule, but it is not itself an ADU or solar decision. The Childers citation comes from the Marina opinion's own text.
