HOA Approval for Home Additions & ADUs in Jacksonville, FL: 2026 Guide | Sunshine State Pro

Why HOA Approval Catches Jacksonville-Area Homeowners Off Guard

You've picked out the contractor, budgeted for the project, and started imagining the finished space then someone mentions you'll need your HOA's sign-off before a shovel goes in the ground. For homeowners planning a home addition, an accessory dwelling unit (ADU), or a mother-in-law suite in a planned community around Jacksonville, Fernandina Beach, or St. Johns County, that approval step is real, it's governed by state law, and it can either move fast or drag on for months depending on how the request is handled.

The good news: Florida law actually limits what an HOA can require of you, and a 2026 change tightens that limit further. Here's what Florida Statute 720.3035 says your association can and can't do, what changed this year, and what to do if a request gets denied.

What Your HOA Can (and Can't) Control Under Florida Law

Under Florida Statute 720.3035, an HOA's authority to review and approve the location, size, type, or appearance of a structure only exists to the extent it is "specifically stated or reasonably inferred" in the declaration of covenants or in published guidelines authorized by that declaration. In plain terms: your board can't invent a new restriction on the spot. If your addition or ADU isn't addressed anywhere in the governing documents, the association's authority to block it is a lot thinner than most boards assume and the statute requires whatever standards do exist to be applied "reasonably and equitably" to every owner, not selectively.

The law also draws a hard line around a few specific things an HOA can never require review of, regardless of what the declaration says:

• The interior of a structure that isn't visible from your parcel's frontage, an adjacent parcel, adjacent common area, or a community golf course.
• A central air conditioning, heating, or ventilating system, if it isn't visible from the frontage or common areas and is substantially similar to a system the association has already approved or recommends.

And if your declaration offers you a choice a range of approved materials, sizes, designs, or placements — the association cannot restrict you to a narrower list than what the declaration actually provides.

The 2026 Change: Your HOA Can No Longer Wait on Your Building Permit First

Governor DeSantis signed House Bill 803 on May 7, 2026, with most provisions taking effect July 1, 2026. HB 803 is best known for exempting some small residential jobs under $7,500 from needing a building permit at all we covered that piece separately in our $7,500 permit exemption guide. But the bill also amends Section 720.3035 directly, and this part matters for anyone building a real addition or ADU in an HOA community.

As of the July 1, 2026 effective date, an association, architectural review committee, or similar committee "may not require a building permit to be issued by a governmental authority to an owner as a prerequisite" for the association's own review of the project. Before this change, some HOAs made homeowners get their county or city permit first, then submit that permit as part of the architectural review packet adding weeks to an already sequential process. Under the new rule, you can pursue HOA approval and your local building permit in parallel instead of waiting on one to unlock the other.

Setbacks: Why Your HOA Can't Override County or City Zoning

Setback fights are one of the most common friction points on addition and ADU projects, especially on corner lots or parcels backing up to an easement. Florida law addresses this directly in 720.3035(3): unless the declaration specifically states otherwise, each parcel is treated as having only one front for setback purposes, even if it's bordered by a roadway or easement on more than one side. And if the declaration doesn't spell out its own setback limitations, the applicable county or municipal setback rules apply by default the HOA cannot enforce a setback that conflicts with what your local building department already requires.

That's exactly why our home addition zoning and setback guide tells homeowners to pull county zoning requirements before assuming the HOA's number is final. It's not always the HOA that gets to set that boundary.

If Your HOA Denies Your Addition or ADU, Here's What the Law Requires Them to Tell You

A denial isn't the end of the road, and it isn't supposed to be vague. Under 720.3035(4)(a), if the association or its architectural committee denies your request, it must give you written notice stating with specificity which rule or covenant it relied on and exactly what part of your proposed improvement doesn't conform to it. A form letter that just says "denied" without pointing to a specific covenant doesn't meet that bar.

The statute also gives you real recourse. Under 720.3035(4)(b), if the association unreasonably, knowingly, and willfully infringes on your rights under the declaration, you're entitled to recover damages caused by that infringement including costs and reasonable attorney's fees. Section (5) closes a common loophole too: the HOA can't fall back on an unwritten policy or a restriction that's inconsistent with the declaration as a defense, whether or not that policy has been applied consistently to other owners. If a denial doesn't cite a specific, documented rule, that's worth raising before you assume the project is dead.

We also see this come up on ADU projects in St. Johns County communities like Nocatee and Ponte Vedra, where HOA design guidelines are often more detailed than the county's own ADU rules another reason to get the written denial (or approval) in hand before finalizing plans.

Hurricane Protection Is a Special Case Your HOA Can't Block

There's one category of improvement where Florida law takes discretion away from the board almost entirely: hurricane protection. Under 720.3035(6), every homeowners' association in the state regardless of when the community was created must adopt hurricane protection specifications covering color, style, and other factors the board deems relevant, and those specifications have to comply with the applicable building code. Once specifications are in place, the board cannot deny an application to install, upgrade, or replace hurricane protection that conforms to them.

"Hurricane protection" is defined broadly under the statute: roof systems that meet Florida Building Code and ASCE 7-22 standards, permanent fixed storm shutters, roll-down track shutters, impact-resistant windows and doors, polycarbonate panels, reinforced garage doors, erosion controls, and exterior fixed generators and fuel storage tanks all qualify. If your project includes hurricane-rated impact windows as part of a larger renovation, that piece of the scope has real statutory protection even if the rest of the addition is subject to normal architectural review.

How Sunshine State Handles HOA Review as Part of Your Project

John Belizario, Sunshine State's founder, built the company around a simple standard: "My goal is not just to do a good job but make sure my customer understands and is happy with the final result." HOA review is one of the places that standard matters most, because it's the step homeowners are least equipped to navigate on their own and most likely to get stuck on if nobody's tracking the paperwork.

Because our licensed general contractor team operates as a full-service company with engineers, estimators, project coordinators, and project managers working together rather than a homeowner juggling separate vendors HOA architectural review packets get prepared alongside your county permit application instead of after it. That's especially useful now that HB 803 allows the two processes to run in parallel. If a request does come back denied, our team can help you read the written notice, confirm it cites an actual covenant, and figure out whether the plan needs adjusting or the denial needs pushing back on.
