Thinking about adding more living space or rental income near Lake Morton? You are not alone. Many owners weigh a backyard accessory dwelling unit against converting to a duplex, and the rules can feel complex. In this guide, you will learn what each option means, what is allowed in Historic Lake Morton, how 2025 Florida law shifts the ADU landscape, and the steps to get approved. Let’s dive in.
Duplex vs. ADU, in plain English
A duplex is one building with two full dwelling units. It is a primary use and only allowed where zoning permits two-family homes. An accessory dwelling unit, or ADU, is a smaller, secondary home on the same lot as a single-family house, either attached or detached. Florida law defines ADUs and encourages local ordinances that allow them. You can review the state definition in Florida Statutes Section 163.31771 and Lakeland’s Land Development Code overview for local rules.

What zoning allows near Historic Lake Morton
Duplex rules on Lake Morton blocks
Most parcels in the Lake Morton historic districts are zoned single family. The City notes that two-family dwellings are not allowed in RA single-family zones. Duplexes are permitted by right only in RB districts and may be considered as Conditional Uses in some MF and O-1 districts, which triggers concept plans and public hearings. Check your parcel’s zoning first, since that answer usually decides the path. See the City’s guidance in the Planning and Zoning FAQs.

ADUs on single-family lots
ADUs are treated as secondary to a single-family home and can be allowed in single-family areas if you meet ADU standards and obtain approvals. In Lake Morton’s historic districts, ADUs require compatibility review and historic design approval before building permits. This route is often more feasible than a duplex on RA-zoned lots.

Historic district design review
Historic Lake Morton has an overlay that safeguards the neighborhood’s character. Exterior changes, including new ADUs or visible alterations for a two-family conversion, are reviewed by the Historic Preservation Board. Expect design guidelines to shape placement, scale, materials, and visibility so the accessory unit remains subordinate to the main home.

2025 Florida updates that matter
In 2025, the Legislature adopted changes that strengthen statewide support for ADUs. CS/CS/SB 1730 sets deadlines for local ADU ordinances and limits certain local restrictions, such as mandatory owner-occupancy or new off-street parking burdens. Lakeland is updating procedures and code language to align with the new law, so always confirm current local requirements before you file.

Site and design constraints to expect
Every lot is different, but several recurring factors shape feasibility in Lake Morton:
- Number per lot and placement. Lakeland commonly limits you to one ADU per lot and steers detached units to rear or interior side yards with tight setbacks. Review the LDC tables reproduced in public documents to understand the typical patterns.
- Lot coverage and accessory footprint. The City has considered amendments that reduce maximum lot coverage and limit the combined size of accessory structures, which can shrink the envelope for a detached ADU. Check the most recent legal notices and adopted text.
- Visibility and compatibility. Historic review often requires ADUs to be visually subordinate and screened, especially if visible from the street.

How to get approved in Lakeland
Quick step-by-step
Verify zoning and historic status. Use the City’s address lookup and confirm with the Planner on Demand whether your lot is in an area that allows ADUs and what approvals you will need. Start here: Planning & Zoning FAQs.
Prepare an ADU concept. Sketch placement, size, height, and exterior design that aligns with the historic guidelines.
Secure compatibility and historic approvals. ADUs typically go through compatibility review. In the historic districts, you will also need a Certificate of Review or Appropriateness from the Historic Preservation Board. See: Historic Preservation.
Apply for building permits. After approvals, submit plans through the City’s iMS portal and follow building code for life safety, electrical, and plumbing. Submittal steps and meeting calendars are outlined here: How to Apply.
Final inspections and occupancy. Complete inspections and confirm any conditions of approval before you advertise for rent or host guests.
ADU or duplex, which fits your lot?
If your parcel is RA single family, a duplex is not permitted without a zoning change or a Conditional Use process, which includes public hearings and higher risk. An ADU is often the more practical path to add a second unit in Lake Morton, although historic review can extend timelines. If you already have RB zoning, a duplex may be possible by right, but design and neighborhood context still matter.

Pro tips for Lake Morton owners
- Start early with the City. A quick conversation with Planning and Historic Preservation staff can save weeks.
- Design for compatibility. Keep the ADU behind the main house where possible, scale it modestly, and match materials and rooflines to the primary structure.
- Watch the details. Separate utility meters and total accessory footprint are frequent sticking points and may be limited by current or proposed code. Confirm before you design. See the LDC tables reproduction: Article 4 standards.
- Know your rental plan. Florida’s 2024–2025 changes strongly support ADU rentals, and some provisions address homestead and assessment treatment. Verify local procedures and tax implications with the Polk County Property Appraiser. Review the 2025 bill text for context: State bill on rental and assessment provisions.
