New Jersey HOA ADUs & Modifications

Section 1: Overview — ADUs and modifications in New Jersey

Start with two things a New Jersey community association cannot do. It cannot prohibit a rooftop solar collector (N.J.S.A. 45:22A-48.2),¹ and it cannot prohibit an electric-vehicle charging station (N.J.S.A. 45:22A-48.4).² The Legislature wrote both protections into the Planned Real Estate Development Full Disclosure Act — PREDFDA for short — and both reach condominium and planned-community associations alike. Accessory dwelling units sit in a different place. They remain a question of municipal zoning and the recorded declaration, with no confirmed state law that preempts an association's own documents.³ New Jersey builds its framework in layers rather than in a single code. The New Jersey Condominium Act (N.J.S.A. 46:8B-1 et seq.) supplies the substantive rules for condominiums.⁴ PREDFDA (N.J.S.A. 45:22A-21 et seq.) is the registration-and-disclosure act, administered by the Department of Community Affairs (DCA) and reshaped by the 2017 Radburn Amendment.⁵ And the older Horizontal Property Act (N.J.S.A. 46:8A-1 et seq.) still governs property created under that regime. On modifications, the solar and EV provisions draw two protected categories: an association may set reasonable placement and installation standards, but it may not impose a flat ban.¹ Whether an owner may build an ADU turns on the municipal zoning ordinance under the Municipal Land Use Law and on the community's declaration — not on any statewide statute that overrides governing documents.³ Four federal rules bind every New Jersey association no matter what the state does: the Freedom to Display the American Flag Act of 2005 for the United States flag,⁶ the FCC's Over-the-Air Reception Devices (OTARD) rule for antennas and satellite dishes,⁷ the Fair Housing Act for reasonable disability modifications at the resident's expense,⁸ and Title III of the Americans with Disabilities Act for common-area facilities that serve as public accommodations. The sections that follow lay out the framework, the compliance obligations it creates, and the legislative and judicial activity through July 16, 2026.

Section 2: The legal framework

2A. The layered statutes and the regulator

New Jersey is not a UCIOA state. Its framework is bespoke and layered, so the first analytical step is always the same: identify the type of community and the combination of statutes and governing documents that applies to it. The Condominium Act (N.J.S.A. 46:8B-1 et seq., effective January 7, 1970) sets out what an association may and must do at N.J.S.A. 46:8B-14, including adopting and enforcing rules that govern the use of the property and the common elements.⁴ PREDFDA (N.J.S.A. 45:22A-21 et seq.) is the registration-and-disclosure statute, administered by the DCA's Division of Codes and Standards; it governs how planned real estate developments register, what a public offering statement must say, and how control passes from developer to owners, and it applies to condominiums, cooperatives, and planned communities alike.⁵ The Radburn Amendment (P.L. 2017, c.106) rewrote PREDFDA's governance provisions, and the DCA followed with the Radburn Regulations (N.J.A.C. 5:26), published and effective May 18, 2020. Those rules require, among other things, that every unit owner counts as a member, that board nominations stay open, that balloting be anonymous, that ballot tallies be public, and that owners get access to records.⁵ The Horizontal Property Act (N.J.S.A. 46:8A-1 et seq.) governs the older horizontal-property regimes.

The DCA is an active regulator on registration and governance. Its Bureau of Homeowner Protection administers PREDFDA and the Radburn Regulations and takes owner complaints.⁵ New Jersey does not license community association managers; a real-estate broker's license comes into play only when a manager crosses into brokerage or leasing — renting, selling, or advertising units.⁹ General architectural-review authority is a creature of the master deed, the bylaws, or the declaration, not of statute. When a New Jersey court reviews an architectural decision, it generally asks two questions: did the association act within the authority its governing documents grant, and did it exercise that authority reasonably and in good faith — subject to the category-specific statutory protections and the federal overlays described below.

2B. Solar, EV charging, and signs

Solar rests on N.J.S.A. 45:22A-48.2 (P.L. 2007, c.153). An association may not adopt or enforce any restriction, covenant, bylaw, rule, or regulation that prohibits a solar collector on the roof of a single-family dwelling unit the owner solely owns, or on the roof of a townhouse dwelling unit where the owner — not the association — must repair the roof under the governing documents.¹ The association may still write reasonable rules: on installer qualifications, certification, and insurance; on where the collectors sit on the roof; on concealing support structures, fixtures, and piping; on color; and on aggregate size or number. What it may not do is adopt or enforce a rule that raises the installation or maintenance cost by more than an estimated 10 percent of the total cost of the initial installation — labor and equipment included — or one that keeps the collectors from working at their intended maximum efficiency.¹ The provision does not apply while the association is still under developer control. Because it lives inside PREDFDA, it reaches condominium and planned-community associations alike, though its protection keys to the specified owner-controlled roofs rather than to shared roofs or common property.

EV charging rests on N.J.S.A. 45:22A-48.4 (P.L. 2020, c.108, signed October 19, 2020), which supplements PREDFDA and so applies to condominium and planned-community associations alike.² An association may not prohibit or unreasonably restrict the installation or use of an electric-vehicle charging station in a unit owner's designated parking space, and it must generally let an owner install and use one, subject to reasonable conditions. The owner carries the costs — installation, electricity, maintenance, and removal — must hire a licensed electrician, must meet the association's architectural standards, and must keep a homeowner's liability policy of $100,000 that names the association as a certificate holder entitled to notice of cancellation.² The association, for its part, may recover reasonable review costs, including engineering and legal fees; may require an escrow of estimated fees; may hold an application while necessary infrastructure is upgraded; and may deny an application it reasonably concludes is a life-safety risk. Miss the deadline, though, and the default favors the owner: an application the association does not deny in writing within 60 days of receipt is deemed approved, unless the delay traces to a reasonable request for more information.²

Political signs come in at the framework level, through Mazdabrook Commons Homeowners' Ass'n v. Khan, 210 N.J. 482 (2012), decided June 13, 2012. There the New Jersey Supreme Court struck down a near-total ban on residential signs as a violation of the free-speech clause of the state constitution, while confirming that associations may still adopt reasonable time, place, and manner restrictions.¹⁰ The practical upshot: solar and EV charging are protected categories where a prohibition simply will not hold, while most other modifications turn on the declaration, subject to the federal overlays. HOA Weekly treats solar at the framework level here; our dedicated Solar Rights coverage takes the category in full.

2C. ADUs and federal overlays

New Jersey has no confirmed statewide statute that overrides an association's governing documents on ADUs. Permissibility runs on two layers. The municipal zoning ordinance under the Municipal Land Use Law (N.J.S.A. 40:55D-1 et seq.) decides whether and how an ADU may be built on a given lot, and the community's declaration decides whether it is allowed inside the association.³ That two-layer test is what separates New Jersey from HOA-preemption states such as California (Civ. Code § 4751) and Colorado (HB 24-1152), which bar associations from effectively prohibiting ADUs. New Jersey has enacted no such association-level preemption.¹¹ Bills to set statewide ADU standards — A2792 and S1106, for example — have been introduced but never enacted.³

A separate recent law, the Structural Integrity and Reserve Funding law (P.L. 2023, c.214, signed January 8, 2024, and amended by P.L. 2025, c.132), requires periodic structural inspections of certain residential condominium and cooperative buildings and capital reserve studies with 30-year funding plans.¹² It is a reserves-and-structural-integrity matter, not a modification-approval statute; HOA Weekly covers it in its governing-statute and reserves material.

Four federal overlays bind every New Jersey association, whatever the state framework says. The Freedom to Display the American Flag Act of 2005 bars an association from preventing display of the United States flag, subject to reasonable time, place, and manner rules.⁶ The FCC OTARD rule (47 C.F.R. § 1.4000) bars restrictions that impair the installation, maintenance, or use of covered antennas and satellite dishes within an owner's exclusive-use area.⁷ The Fair Housing Act (42 U.S.C. § 3604(f)(3)) requires an association to permit reasonable modifications for disability, generally at the resident's expense.⁸ And Title III of the Americans with Disabilities Act reaches common-area facilities that qualify as public accommodations. None of the four is a New Jersey statute.

Section 3: Compliance obligations created by the framework

A. Architectural review process obligations

Review authority and process come first from the master deed, bylaws, or declaration (DECLARATION; applies to BOTH condominiums and planned communities), which set up the architectural-review committee, the submission requirements, and the decision standards. The Condominium Act lets the association adopt, distribute, amend, and enforce rules governing the use of the property and the common elements (N.J.S.A. 46:8B-14(c); STATE STATUTE; CONDOMINIUMS).⁴ How the association runs that review — open-meeting practice, notice, recordkeeping — must track PREDFDA and the Radburn Regulations, N.J.A.C. 5:26 (STATE STATUTE and regulation; BOTH).⁵ Put decisions in writing and keep the records, because owners hold access rights to association records and a right to challenge decisions through the channels below.

B. Modifications the association must permit

Solar collectors on qualifying owner-controlled roofs must be allowed; a flat prohibition will not hold, and only reasonable installation standards survive (N.J.S.A. 45:22A-48.2; STATE STATUTE; BOTH).¹ Electric-vehicle charging stations in a designated parking space must be allowed, subject to reasonable conditions, insurance, and cost allocation (N.J.S.A. 45:22A-48.4; STATE STATUTE; BOTH).² Display of the United States flag must be allowed, subject to reasonable time, place, and manner rules (Freedom to Display the American Flag Act of 2005; FEDERAL; BOTH).⁶ Covered antennas and satellite dishes within an owner's exclusive-use area must be allowed (OTARD, 47 C.F.R. § 1.4000; FEDERAL; BOTH).⁷ Reasonable modifications a resident needs for a disability must be allowed, generally at the resident's expense (Fair Housing Act, 42 U.S.C. § 3604(f)(3); FEDERAL; BOTH),⁸ and common-area public accommodations answer to ADA Title III (FEDERAL; BOTH). In each category the association may separate reasonable placement and conditions from a prohibition; only the prohibition is off the table.

C. ADU obligations and limits on HOA authority

No statute requires an association to permit ADUs against its declaration (no STATE STATUTE reaching governing documents). Municipal zoning under the Municipal Land Use Law binds the locality and decides whether an ADU is a permitted use on the lot (municipal ordinance; BOTH, as applicable).³ Inside the community, the declaration governs, and an association may lawfully restrict or prohibit ADUs where its governing documents say so (DECLARATION; BOTH).

D. Enforcement, dispute resolution, and appeal obligations

The Condominium Act requires an association to give owners a fair and efficient procedure for resolving housing-related disputes as an alternative to litigation (N.J.S.A. 46:8B-14(k); STATE STATUTE; CONDOMINIUMS),⁴ a phrase the Appellate Division read broadly in Bell Tower Condominium Ass'n v. Haffert (2012) to reach disputes that arise from the condominium relationship.¹³ PREDFDA and the Radburn Regulations likewise require alternative dispute resolution for certain disputes (STATE STATUTE and regulation; BOTH), and an owner may notify the Commissioner of Community Affairs if an association fails to provide it.¹³ Any procedure the declaration itself requires applies too (DECLARATION; BOTH). Covenant-enforcement and injunctive matters go to the Superior Court, Chancery Division; damages actions go to the Law Division; and appeals run to the Superior Court, Appellate Division, with discretionary review by the New Jersey Supreme Court.

Section 4: Recent legislative and judicial activity

A. Recent bills

New Jersey's recent activity here is about reserves and structural integrity — the legacy of the Surfside collapse — rather than about architectural modification as such, though the two meet at the budget. Here are the two measures that matter, and where each stands.

B. Recent appellate rulings

One appellate decision frames the current governance picture — a challenge to the DCA's own Radburn rules.

C. Active legislative debates

Two debates are live. The first is whether New Jersey will set statewide ADU standards and, in some versions, cap association authority over ADUs — bills such as A2792 and S1106, which remain pending and unenacted as of July 16, 2026.³ The second is portable solar. The Garden State Balcony Solar Act (S2368/A4836) would bar associations from prohibiting portable solar generation devices — UL-certified systems up to 1,200 watts — while allowing reasonable size and placement restrictions and voiding any inconsistent governing-document provision. It passed both houses on June 30, 2026 (Assembly 79-0-1, Senate 40-0) and awaits action by Governor Sherrill; it would take effect six months after enactment, and it is not yet law.¹⁶

Section 5: National positioning and related coverage

New Jersey belongs among the strong-statute states, and three features set it apart: a layered statutory structure, an active DCA regulator armed with the Radburn governance rules, and category-specific owner protections for solar (N.J.S.A. 45:22A-48.2) and EV charging (N.J.S.A. 45:22A-48.4) that reach condominium and planned-community associations alike. On ADUs it parts company with the preemption states — California (Civ. Code § 4751) and Colorado (HB 24-1152) — and leaves the question to municipal zoning and the declaration, with no association-level state preemption.¹¹ For a multi-state operator, the takeaway is direct: in New Jersey an association cannot prohibit solar or EV charging, it operates under DCA governance rules and arbitration or ADR channels, and it treats ADUs as a zoning-and-declaration question rather than a protected owner right.

HOA Weekly updates its New Jersey ADUs and Modifications coverage quarterly, as the Legislature, the DCA, and the New Jersey courts act. The federal frameworks noted throughout — the Freedom to Display the American Flag Act, OTARD, the Fair Housing Act, and the ADA — bind New Jersey associations no matter what the state framework does.
