Committee advances bill requiring local governments to allow accessory dwelling units

Senator Gates' bill requiring local governments to allow accessory dwelling units in single-family residential zones was reported favorably by the Florida Senate Community Affairs Committee after debate and amendment.

The measure, CS/SB 184, would require local governments to allow accessory dwelling units — sometimes called carriage houses or granny flats — on lots zoned for single-family residential use while exempting planned unit developments and master planned communities. Senator Gates said the bill "requires local governments to allow accessory dwelling units, or ADUs, in any area zone for single family residential use," and emphasized the measure is intended as a private property–rights and supply-side strategy because "100% of the costs of developing ADUs are paid for by the property owners."

Committee members questioned how the bill would interact with existing local rules. Senator Osgood asked about financing language that had appeared in earlier drafts; Gates said mezzanine financing language had been removed from the current amendment and would be studied separately. Gates also told the panel the bill "ensures that the individual who owns the property or the family owns the property will not lose their homestead exemption because they build an ADU" whether a family member occupies the unit or it is rented.

Senators pressed on implementation topics the bill leaves to local governments. On parking, Senator Fine asked what the measure would mean in jurisdictions that already struggle with on‑street parking; Gates said the bill prohibits local governments from using parking requirements "for the sole purpose of excluding" ADUs but otherwise leaves parking policy to local authorities. On appearance and design, Senator Leake asked whether the bill would override homeowners association covenants or local architectural standards; Gates said the bill would leave design and aesthetics to local governments, which could adopt preapproved designs or architectural standards for specific neighborhoods.

The bill was amended during committee. A primary amendment was adopted; an amendment-to-the-amendment (barcode 79,116) removed from the bill a prohibition that would have waived impact and mobility fees for ADUs, removed provisions relating to preapproved ADU designs and a reference to manufactured ADUs, and added a requirement that OPOGA study include an evaluation of tiny homes and mezzanine financing as potential tools to meet housing needs. Senator Gates described that change as moving some technical financing and tiny‑home considerations into the mandated study rather than embedding them in statute.

Public testimony included organizational support and comment: Zane Smith with AARP waived in support; Colton Medill of the Florida Chamber waved in support; Rebecca O'Hara of the Florida League of Cities supplied technical feedback, noting drafting approaches to address short‑term rental concerns and pointing out that current law already includes an attestation mechanism tied to affordability that may be strengthened in subsequent drafting. Rebecca O'Hara said it was "great to hear Senator Gates understand the potential [short‑term rental] issue" and advised further drafting work on fee parity and parking exemptions.

Following debate and adoption of amendments, the committee took a roll call on CS for SB 184. The roll recorded affirmative votes by Senator Leake, Senator Osgood, Senator Pacidoma, Senator Sharif, Senator Trumbull, Vice Chair Senator Fine, and Chair Senator McLean; the committee reported the bill favorably.

The vote advances the bill out of committee; Gates said she welcomes additional drafting suggestions from colleagues and expects to continue work to refine issues such as short‑term rental limits, lot‑size and design standards, and fee parity.
