Tips for Building an ADU While Complying with HOA Rules

By: LS Carlson Law March 12th, 2025

However, homeowners in HOA-governed communities must navigate an additional layer of regulations to ensure compliance with association rules. While HOAs cannot impose restrictions that contradict state laws, they often try to enforce their own guidelines that may make the process more difficult.
Understanding how to work within HOA rules while protecting your rights is essential for a smooth ADU approval process. If you encounter unreasonable restrictions or delays, consulting with an HOA attorney can help you challenge unlawful HOA interference.
At LS Carlson Law, our HOA disputes attorneys specialize in helping homeowners defend their rights against unfair association restrictions. If necessary, we can help you sue HOA leadership to ensure compliance with state ADU laws.

HOA Regulations on ADUs

HOAs often impose rules related to property modifications, including ADU construction. While they can enforce certain guidelines, they cannot create blanket bans on ADUs where state law permits them. Homeowners should be aware of the following common HOA-imposed regulations:
Architectural review requirements for ADUs to ensure aesthetic compatibility with the community.
Setback and landscaping guidelines that may affect ADU placement.
Parking restrictions that may require additional spaces for ADU tenants.
Lease terms and rental limitations imposed on ADUs within HOA communities.
Before proceeding with ADU construction, homeowners should review their HOA’s governing documents and, if necessary, consult a homeowner association lawyer to ensure compliance with state and local regulations.

Steps to Take Before Submitting an ADU Application to Your HOA

To improve your chances of getting HOA approval for your ADU, consider the following steps:
Review HOA CC&Rs and Bylaws: Ensure that you understand the rules governing ADU construction in your community.
Check State and Local Laws: Confirm that your ADU plans align with California or Florida state laws, which override restrictive HOA policies.
Prepare a Detailed Proposal: Provide clear construction plans that include architectural renderings, parking solutions, and compliance with zoning laws.
Engage with the HOA Early: Proactively communicate with your HOA board to gauge their concerns and address any potential issues.
Seek Legal Advice if Needed: If your HOA is imposing unreasonable delays or restrictions, an HOA attorney can help ensure that your rights are upheld.
By taking these steps, homeowners can reduce the likelihood of delays and avoid unnecessary conflicts with their HOA.

Common Legal Issues Homeowners Face with HOA ADU Approvals

Even when state law allows for ADU construction, homeowners associations often impose additional requirements that complicate the process. Common legal issues include:
Unreasonable restrictions that go beyond what state law permits.
Selective enforcement where some homeowners receive ADU approvals while others are denied.
Excessive fees or special assessments targeting ADU construction.
Delays in the approval process without legitimate reasoning.
Newly enacted HOA rules designed to block ADUs retroactively.
If you are facing these or other HOA-related issues, consulting a skilled attorney can help you understand your options and take appropriate legal action.

The Limits of HOA Authority Over ADUs

While homeowners associations can enforce community aesthetics and shared property guidelines, their authority over ADU construction is limited by state law. Property owners should be aware of the following:
HOAs cannot impose a blanket ban on ADUs if state law allows them in single-family residential areas.
State laws override HOA restrictions that conflict with government-mandated ADU protections.
Associations must provide fair solutions and reasonable justification for denying an ADU application.
HOAs cannot enforce rules selectively or apply different standards to different homeowners.
If your HOA refuses to comply with state law, seeking legal guidance from experienced attorneys can help you challenge unfair restrictions and pursue a fair resolution.

What to Do If Your HOA Rejects Your ADU Application

Despite state laws protecting homeowners’ rights to build ADUs, some HOAs attempt to block these projects by imposing excessive restrictions or rejecting applications without valid reasoning. If your ADU proposal is denied, consider the following actions:
Request written documentation explaining why the application was rejected.
Review HOA governing documents to determine if the denial aligns with HOA-approved guidelines.
Compare your ADU request to other approved home modifications within the community to ensure fair treatment.
Work with an HOA disputes attorney to challenge unfair denials or excessive requirements.
If the HOA refuses to reconsider an unreasonable denial, you may need to sue HOA leadership to enforce your rights under state law.

When to Take Legal Action Against an HOA for Blocking an ADU

In some cases, homeowners may need to take legal action to ensure their ADU project moves forward. Signs that legal intervention may be necessary include:
The HOA imposes restrictions that violate state law.
Your ADU application is delayed indefinitely without valid reasoning.
The HOA enforces ADU-related rules unfairly among different homeowners.
You are subjected to excessive fines, fees, or special assessments related to your ADU project.
The HOA’s board refuses to communicate or provide a fair resolution.
If you are experiencing these issues, an HOA disputes attorney can provide legal representation and help you sue HOA leadership to ensure compliance with state law.

Negotiating with the HOA board to ensure compliance with state law.
