Guides
Every guide states its jurisdiction and property type, gives the practical answer early, links to official sources, and shows when the sources were checked.
Showing all 74 current guides. Sources-checked dates and next-review dates are listed on each guide.
A denial is usually the start of a review process, not the end: get the written reasons and the exact provision cited, check whether a state statute protects the project type, appeal in writing, and use the agency complaint route that fits (attorney general, contractor board, or public utility commission).
No, for new work: as of the official sources reviewed August 16, 2026, both federal home energy tax credits were terminated for property placed in service or expenditures made after December 31, 2025, by the One Big Beautiful Bill Act (P.L. 119-21). Qualifying 2025 and earlier installations can still be claimed, and an unused Residential Clean Energy Credit (25D) carries forward to 2026 and later years.
Historic-district design review usually still applies to rooftop solar, and it can restrict visibility and placement, but state solar-rights statutes cap how far that review may go. California bars design review that creates unreasonable barriers to solar; Maryland's solar-rights statute expressly does not apply to property on the Maryland Register of Historic Properties.
Usually the lease and your state's law control: the federal, California and New York sources reviewed here do not give a tenant compel a landlord to install a heat pump, and installing one without consent usually risks violating the lease. Landlords must keep existing heating in working order, tenants with disabilities have a federal right to 'reasonable modifications' at their own expense, and the IRS expressly says the residential clean energy credit applies whether you own or rent your home.
In the states with solar-access statutes verified for this guide (California, Florida, and Arizona), an association usually cannot flatly ban rooftop solar: provisions that effectively prohibit solar systems are void or barred, while reasonable location and design restrictions, safety and permitting rules, and utility requirements still apply.
Usually not outright. In states with right-to-charge statutes, restrictions that effectively prohibit or unreasonably restrict an EV charging station in an owner's unit or designated parking space are void — California's Civil Code section 4745 is the strongest example — while reasonable restrictions (rules that do not significantly increase cost or reduce performance) remain enforceable, and safety, zoning, and permit requirements still apply.
It depends on the battery and the state. Solar-rights statutes generally protect solar energy systems — and in some states storage that is part of a solar system — but standalone, grid-charged batteries are often outside those protections, so association restrictions on them are more likely to survive. Fire and electrical safety review remains separate and mandatory.
In most states, recorded covenants and association rules usually control and a clothesline ban may be enforceable — but Florida and Utah have verified statutes that protect clotheslines, and Hawaii's frequently cited statute covers solar devices only.
Usually yes, within the limits of the governing documents and general reasonableness standards. The state statutes reviewed for this guide protect solar devices, not heat pumps by name: the official sources reviewed for California, Florida, Massachusetts, Oregon, Virginia and Washington did not identify a specific heat-pump or mini-split protection. Local law, governing documents, contracts, and general property law may still affect the result.
Usually yes: an association may regulate where and how owners compost through the governing documents and architectural review, and the official sources reviewed for California and Vermont did not identify a specific protection for backyard composting. Municipal organics programs such as Seattle's required food-and-yard collection and California's SB 1383 obligate cities and properties to arrange collection, not to permit a personal bin.
The category of your parking space — deeded, assigned, leased, or open common area — usually decides who must approve an EV charger and who pays for it. Several states, including California and Florida, protect owner-installed charging in deeded or exclusively assigned spaces while still letting associations impose reasonable conditions and cost-shifting rules.
In California and Illinois, tenants have a statutory right to install EV charging equipment in their allotted parking space or leased premises, but only if they meet the conditions the statute allows the landlord to impose — insurance, licensed contractors, cost reimbursement, and removal obligations among them. Most other states have no renter-specific charging statute, so the lease and the landlord's discretion usually control there.
Whether you can install battery storage depends first on where it goes — inside your unit, in a common area, or on shared infrastructure — and second on your state's statutes and the recorded declaration. California protects storage as part of a "solar energy system" (Civil Code sections 714, 714.1, and 801.5); the Florida and Virginia statutes reviewed here protect solar devices but do not by their terms extend to standalone battery storage.
Usually yes for health, safety, and permitting rules, but usually no for outright bans or rules that defeat the statewide protection. The boundary depends on the state statute's exact language and whether it preempts local rules.
The federal sources reviewed do not identify a residential landscaping protection. Protection depends on your state: Colorado, Texas, Florida, and Nevada are verified examples that restrict HOA bans, while each still allows design review, aesthetic standards, and some limits.
Usually yes — three separate approval tracks can apply to the same solar, battery, EV charger, or heat pump project, and no approval substitutes for another: a local building and electrical permit, community-association approval where one exists, and a utility interconnection or service arrangement for systems that connect to the grid.
Usually a hardwired Level 2 (240-volt) charger requires a local electrical permit, and a panel or service upgrade is only sometimes required — a licensed electrician's load calculation decides. Special EV or time-of-use utility rates are optional but often available.
Graywater systems are regulated by state water and plumbing rules, not by one national law. California (Water Code section 14875) and Arizona (Revised Statutes section 49-204) are the clearest verified examples: California's chapter governs construction, installation, or alteration of graywater systems, and Arizona provides that a city, town, or county may not limit residential graywater reuse by rule or ordinance unless conditions are met. Local permits, plumbing codes, and HOA rules may still apply.
Ask before you install. The NAIC's consumer guidance advises checking with your homeowners insurer before making green modifications because not all insurers extend homeowners coverage to solar panels or batteries, the addition can significantly affect the cost of your policy, and some states impose specific obligations. If your insurer will not extend coverage, your state insurance department can identify an authorized insurer that will.
Ground-mounted arrays are usually regulated as structures rather than as rooftop components: local zoning may apply setback, height, and coverage limits, the permit path often differs from rooftop (for example, San Diego requires a building permit for ground-mounted PV more than five feet above the ground), and HOA architectural review applies — but state solar-access statutes reviewed here (California, Oregon, Colorado) generally void provisions that effectively prohibit or unreasonably restrict the system.
Most HOAs, condominiums, and co-ops require written approval before physical changes; a complete application usually covers layout, equipment, cost, expected performance, contractor information, and insurance. Some states set deadlines and treat silence as approval, but the rules come from your governing documents first.
Federal income-tax credits (sections 25C and 25D) reduce the tax you owe when you file, state and utility rebates cut the purchase price or pay cash back, and grants and financing change who pays and when — and each has different eligibility, administrators, and timing.
Check the contractor's license in your state licensing board's official online license search before you sign anything — the search shows status, license class, and disclosed complaints. If something goes wrong, file a complaint with that board; report scams and fraud to the FTC at ReportFraud.ftc.gov.
There is no single national permitting process: a city or county building department (sometimes split into electrical, mechanical, or planning offices) issues permits and enforces state-adopted codes. Identify whether your home is in an incorporated city or an unincorporated county area, then confirm requirements in writing with that office before work begins.
Save every written notice, letter, email, contract, receipt, delivery confirmation, photo, meter reading, and permit document, in an organized file you can produce later. Official guidance — including the FTC, the CFPB, state attorneys general, and public utility commissions — consistently expects consumers to document disputes in writing, keep copies, and attach supporting records when they complain.
Read three documents in order — the declaration (CC&Rs), the bylaws, and the board's rules — and remember that state statutes can override all of them. Request current copies in writing, then check architectural review, exclusive-use areas, common elements, maintenance, and insurance provisions.
Verify a solar contractor's license with your state contractor-licensing board before signing, using the board's official license search; complaints about licensed and unlicensed contractors go to that same board, while deceptive sales and fraud can be reported to the FTC at ReportFraud.ftc.gov.
A rebate is current only if the official program page — the state agency, program administrator, or utility that runs it — currently says so. Program pages state the incentive amount, eligibility rules, and effective dates, so check those before you sign anything. DSIRE and the ENERGY STAR Rebate Finder help you find programs, but the program's own page is the controlling source.
PACE (Property Assessed Clean Energy) financing is repaid as an added assessment on your property tax bill, and the assessment is a lien on the home that usually passes to the next owner. Before signing, check the full cost and term, whether your mortgage allows the lien, and how the assessment would affect selling or refinancing; federal ability-to-repay rules under Regulation Z have applied to residential PACE transactions since March 1, 2026.
It depends on state law and on timing. In California, the Solar Shade Control Act (Public Resources Code sections 25980–25986) limits shading caused by trees placed or grown on another property after a solar collector is installed — a tree may not cast a shadow greater than 10 percent of the collector absorption area between 10 a.m. and 2 p.m. — with an exemption for passive or natural systems. Oregon protects solar access mainly through solar energy easements. Local rules and recorded easements can change the result.
Unpermitted energy work can surface at inspection, insurance claims, and sale: the local authority may require inspection, after-the-fact permits, or correction of the work; insurers may limit coverage for unpermitted installations; and sellers in states like California must disclose known unpermitted work. Cities such as Berkeley and Boulder run amnesty programs for bringing unpermitted work into compliance.
In most states with solar-access laws, a restriction is "reasonable" when it does not significantly increase the cost of the system or significantly reduce its efficiency or performance — and, in some states, only if no alternative design of comparable cost and performance is available. The exact standard and benchmarks vary by state.
It depends on how the system is financed: a paid-off system usually sells with the home, a solar loan is typically paid off at closing or assumed by the buyer, and a lease or power purchase agreement usually must be transferred to the buyer with the solar company's consent — or bought out — under the contract's own terms. Disclosure duties come from state law and the contract, not from any single federal rule.
Solar access laws are state statutes that protect solar energy use in two ways: they void deed covenants, HOA rules, and local restrictions that effectively prohibit or unreasonably restrict solar systems, and they protect sunlight reaching collectors through solar easements and shade-control rules. Coverage and benchmarks vary by state.
A solar easement is a written property right to receive sunlight across a neighbor's land for a solar energy system. It must be created by a written instrument with a measurable description of the protected space, and in most states it is recorded like other easements and runs with the land. It is separate from — and usually needs to be combined with — state solar access laws, which protect solar equipment from outright restrictions.
The recorded declaration and state statutes decide the category of each roof, wall, or parking space, and the category usually decides who must approve a solar, battery, EV-charger, or other project. The terms are defined by statute, assigned by the declaration, and are not interchangeable.
Disclosure duties come from state law, the solar contract, and general property law — there is no national solar-specific disclosure form. The reviewed state forms (Oregon, Washington) ask about additions and whether building permits and final inspections were obtained, and California requires a defined transfer-disclosure package for common interest development sales (Civil Code section 4525) plus buyer disclosure for shared-roof solar (Civil Code section 4746).
Home battery installations are permitted and inspected locally under state-adopted electrical, building, and fire codes. Most homes need at least an electrical permit, and indoor, outdoor, and garage placements all carry fire code requirements that vary by jurisdiction — confirm the exact rules in writing with your local building department before work starts.
Keep everything you sent and everything you received: the application, proof of delivery, the written decision, requests for more information, correspondence, and inspection reports. Federal and state consumer-protection guidance consistently treats your copies as the backbone of any later dispute.
Keep the documentation that proves what you bought, what it cost, when it was installed, and that it meets the program's requirements: itemized receipts and invoices, the manufacturer's certification or qualified-manufacturer identification (QMID) where required, placed-in-service documentation, and the program paperwork for any rebate you receive. The IRS says to keep records as long as needed to prove the items on your tax return, and rebate programs run by states, territories, and Tribes set their own paperwork rules.
Check the contractor's license, get the full written proposal (equipment, price, financing, and performance assumptions), compare the terms against consumer-protection rules — including the FTC's three-day cooling-off rule for door-to-door sales and state licensing requirements — and verify the tax-credit eligibility and installation-date terms before signing.
When the combined electrical load of solar, a battery, an EV charger, and a heat pump exceeds what your panel and service can safely carry, an upgrade is usually required — but there is no single national rule. Your local electrical code decides when the work needs a permit, and your utility decides what service work it will do, approve, and charge for.
For the federal residential clean energy credit (25D) and energy efficient home improvement credit (25C), the date the property is installed and placed in service is the key date — and, as amended in July 2025, both credits end for property placed in service (25C) or expenditures made (25D) after December 31, 2025. The federal state-run rebate programs (HOMES and HEEHRA) run on a longer clock: funds remain available through September 30, 2031. Dated records prove which side of the cutoff your project falls on.
Start free: call or email your building department, utility, and state attorney general's consumer office for questions and complaints. Hire a licensed electrician for any wiring, a licensed engineer when your building department requires sealed plans, a tax professional when claiming credits or reviewing financing, and an attorney when a dispute, lien, or fraud is involved.
There is no single national rule: outdoor heat pump units are governed by local zoning setbacks, local noise ordinances, mechanical (and usually electrical) permits, and — in associations — architectural review under the governing documents. In the verified examples, Portland bars outdoor mechanical equipment from the required front setback and limits units in side or rear setbacks to five feet high and screened from neighbors, New York City caps HVAC equipment noise at 42 dBA (45 dBA for multiple units) measured at a neighbor's open window, and both Portland and San Diego require a mechanical permit for heat pumps, condensing units, and mini-splits.
No single rule controls a green home project. For most questions the controlling authority is the most specific binding rule issued by the highest body with jurisdiction: enacted statute outranks regulation, court opinion, PUC order or tariff, local code, agency guidance, permit office, utility interconnection rules, recorded governing documents, and contract.
In most condominiums the roof above your unit is a common element controlled by the association, so putting solar panels on a shared roof usually requires association approval — but state statutes set the limits of that control, including California's insurance, site-survey, and equitable-allocation rules for multifamily common-area roofs. The recorded declaration and your state's statutes decide the outcome, so check both before starting.
Drainage and mosquito control around a home are mostly the property owner's job: water that falls on your roof and yard is yours to manage, overflow from rain barrels and gutters must be directed away from buildings, and standing water that breeds mosquitoes is something health agencies expect you to eliminate. The exact rules come from local drainage codes and health departments, with a few state laws like Colorado's residential rainwater collection statute.
It depends on your state and local assessment rules. California, Florida, and Texas each have official rules that keep some or all of the value of qualifying renewable energy devices out of the property tax base, but the details — device definitions, deadlines, and how long the protection lasts — differ by state.
Arizona residential solar usually requires a local permit and inspection path plus a separate utility interconnection approval. HOA, ownership, and contract questions are separate layers. The exact permit, code edition, fees, utility process, and approval sequence depend on the city or county, project design, property documents, and electric provider; verify them for the address before work begins.
Usually not by an outright ban. For a planned community, A.R.S. § 33-1816 bars an association from prohibiting a defined solar energy device, but permits reasonable placement rules that do not prevent installation or impair the device; condominiums, common elements, local codes, utilities, and older deed instruments require separate analysis.
California Civil Code sections 714 and 714.1 generally bar an effective prohibition of a compliant household rooftop solar system, but a condominium association may impose reasonable common-area, roof-maintenance, approval, and indemnity provisions. The roof's legal classification, local permits, and the written approval record still matter.
California's Solar Shade Control Act applies narrowly to post-installation tree or shrub shading of a solar collector: more than 10 percent of the collector absorption area between 10 a.m. and 2 p.m. local standard time.
For a California common-interest development, an association that requires approval for a solar energy system generally must process the request like an architectural modification, issue its approval or denial in writing, and may trigger deemed approval if it does not deny the application in writing within 45 days after receipt. A reasonable request for additional information is an express exception, and HOA deemed approval does not replace permits, safety requirements, or utility review.
Usually, no. California law makes HOA governing-document provisions void when they effectively prohibit or restrict a solar energy system, subject to reasonable restrictions and to safety, permitting, and utility requirements.
Usually not by an effective prohibition or an unreasonable restriction when the station is in the owner's unit or designated parking space in a California common-interest development. California Civil Code section 4745 still permits reasonable restrictions and requires compliance with local safety, building, zoning, land-use, and permit requirements.
Colorado law bars HOAs and other common interest communities from prohibiting xeriscape, nonvegetative turf grass, or drought-tolerant landscapes as ground cover — for attached single-family homes under C.R.S. 38-33.3-106.5(1)(i)(I)(A) and for detached single-family homes under the broader (1)(i.5) — while still allowing design guidelines, review, and reasonable limits. Rain barrels are protected separately.
Colorado homeowners may collect rooftop precipitation in up to two rain barrels with a combined capacity of 110 gallons or less, used for outdoor purposes on the property where collected — no permit is required. The water cannot be used for drinking or indoor household purposes, and common interest community associations may not prohibit such barrels, though placement and aesthetic rules may still apply.
Colorado law (C.R.S. 38-33.3-106.8) prohibits a common interest community association — including HOAs, condominiums, and cooperatives — from banning a unit owner's level 1 or level 2 EV charging system in the unit, an assigned or deeded parking space, or a shared parking space, subject to safety, registration, and reasonable aesthetic conditions and cost rules.
Usually, no. Florida Statutes section 163.04 makes local ordinances and deed restrictions, covenants, declarations, and approval entities powerless to prohibit, or effectively prohibit, solar collectors — though an association may direct the roof location within a south-facing 45-degree range and apply rules that do not effectively prohibit the installation.
Florida law does not require homeowners insurers to cover rooftop solar equipment — coverage depends on the policy — but Florida rules do govern the coverage offers insurers must make, roof-age limits on refusing or nonrenewing a policy, the optional separate roof deductible, and the claims process. Ask your insurer in writing before you install, and keep the answer with your policy.
Usually, no. Hawaii Revised Statutes §196-7(a) protects an owner of a single-family dwelling or townhouse from a private agreement that prevents installation of a solar energy device. The protection does not remove design, registration, contractor, insurance, roof-warranty, permit, utility, or property-ownership conditions.
A Hawaii condominium owner needs written board consent for a solar-energy-device installation under HRS §514B-140(c)(1). Larger or material alterations can also require the approvals described in §514B-140(b), and a project affecting a common element, limited common element, electrical system, or shared roof needs a property-specific review. Local permits and utility requirements are separate.
Sometimes. Maryland Real Property § 2-119 protects a solar collector system on a roof or exterior wall that the property owner owns or has the right to use exclusively, but it allows an association to impose restrictions that are reasonable under the statute and gives an association broader authority over common areas and common elements. Historic-property and property-ownership facts can change the result.
Usually, no outright ban and no approval requirement: since April 2, 2025, Michigan's Homeowners' Energy Policy Act makes homeowners' association agreement provisions that prohibit — or require association approval for — installing an EV charger invalid and unenforceable, subject to local requirements and except in common areas or on shared roofs.
In Michigan, a member whose homeowners' association violates the Homeowners' Energy Policy Act (2024 PA 68, effective April 2, 2025) may bring a civil action against the association for damages, and the court may award reasonable attorney fees and costs if the member prevails; the act creates no agency complaint or enforcement process, so a well-documented file matters.
Michigan's Homeowners' Energy Policy Act (2024 PA 68) makes homeowners' association agreement provisions that ban, or require association approval for, energy-saving improvements — including clotheslines, heat pumps, rain barrels, EV chargers, and solar — invalid and unenforceable, subject to reasonable limits and local rules.
Under Michigan's Homeowners' Energy Policy Act (2024 PA 68), every homeowners' association must adopt a written solar energy policy statement, give members a copy within 30 days of adoption or on request, and post it online if it has a website. The act controls the policy's content.
Under Michigan's Homeowners' Energy Policy Act (2024 PA 68, effective April 2, 2025), an HOA may deny a solar application or require removal only on the narrow grounds the act lists, and may impose conditions only within strict production, cost, and design limits.
Usually only within limits. A Nevada HOA may adopt rules on rooftop solar placement and appearance, but it must approve or deny a qualifying request within 35 days (15 days if it has no solar rules), must base any denial on its adopted rules, and a request it ignores is deemed approved.
Sometimes. North Carolina General Statutes § 22B-20 generally makes a land-running covenant that prohibits or effectively prohibits a solar collector on covered residential property void and unenforceable, but it permits reasonable location and screening rules, preserves specific front-facing visibility restrictions, and excludes certain multi-story condominiums. HOA authority, local approvals, utility interconnection, and roof ownership remain separate questions.
Usually not by a blanket covenant: Texas Property Code section 202.010 voids provisions that prohibit or restrict a property owner's solar energy device, but it preserves specific location, ownership, warranty, approval, safety, and development-period exceptions.
The official sources reviewed for Texas identify a state-level statute, agency, or utility source relevant to water-saving landscaping. That does not by itself approve the project: the exact section, property type, local authority, utility process, and governing documents still have to be checked.
Texas Property Code §202.007 generally prevents a property owners' association from banning or restricting an owner's rain barrel or rainwater harvesting system. The protection is conditional: location, visibility, color, materials, common property, local rules, plumbing, drainage, and the association's statutory exceptions still matter.
