Popular homeowner questions

Can a California HOA ban rooftop solar?

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.

Recent rule change: United States

Under the One Big Beautiful Bill Act (Public Law 119-21, enacted July 4, 2025), the Energy Efficient Home Improvement Credit (section 25C) is not allowed for property placed in service after December 31, 2025, and the Residential Clean Energy Credit (section 25D) is not allowed for expenditures made after December 31, 2025. IRS FAQs published August 21, 2025 (IR-2025-86) confirm the termination dates. Work completed in 2025 or earlier may still qualify under the rules in effect for that year. Source checked 2026-08-16.

What is a solar easement, and how do I create and enforce one?

A solar easement protects a defined path of sunlight across another property through a written property instrument. Its terms, boundaries, and recording determine what it protects. North Dakota and Montana provide easement mechanisms; Wyoming instead has a distinct beneficial-use and solar-permit framework. None of these mechanisms alone supplies HOA approval or rights to a shared roof.

What should I check before signing a residential solar contract?

Before signing, check the installer, equipment, total price, financing, warranties, roof costs, savings assumptions, and cancellation terms. Federal cooling-off rules and state contract protections have different triggers. Arizona, South Carolina, and Pennsylvania examples below show why the contract type and location matter.

Can an Indiana HOA restrict rooftop solar?

Indiana has a conditional solar petition process, not a universal ban on HOA restrictions. First check whether the HOA is covered by the statute and when the system was approved or installed. If the chapter applies, a qualifying owner can gather the required member signatures and submit the proposal, subject to the statute’s location, design, and warranty exceptions.

What does Michigan's Homeowners' Energy Policy Act protect?

Michigan protects listed energy-saving improvements, including EV-supply equipment, air- and ground-source heat pumps, clotheslines, and rain barrels, without HOA approval. Solar energy systems follow a separate application process. These protections do not apply to work in common areas or on shared roofs; confirm that the installation area is yours to use.

Can a Texas HOA restrict my rain barrel or rainwater system?

Texas protects rain barrels and rainwater-harvesting systems, subject to specified property, street-location, appearance, and visible-equipment rules. A narrow statutory exception also excludes certain large developments. Use the actual site and the association’s cited exception rather than a blanket yes or no.

Can a Texas HOA restrict rooftop solar?

Texas limits HOA solar prohibitions, but the result depends on the system’s location, roof design, warranties, prior approval, and any qualifying development-period restriction. Check the enumerated exceptions before accepting a ban or installing equipment.
