Martin County’s Backyard Revolution: How Smart Property Surveying is Maximizing ADU Value and Placement

Martin County is experiencing an unprecedented shift in housing policy that’s creating new opportunities for homeowners to maximize their property value. Martin County Commissioners voted Aug. 26 to begin exploring changes to county policy that could allow accessory dwelling units, or ADUs, as part of an effort to expand affordable housing options. This groundbreaking development, combined with Florida’s new statewide ADU legislation, is positioning Martin County at the forefront of a housing revolution that promises to transform residential properties across the region.

The Perfect Storm: Policy Changes Meet Housing Demand

Florida’s housing landscape has fundamentally changed with the passage of Senate Bill 184 in 2024. In June 2024, Governor Ron DeSantis signed Senate Bill 184 (SB 184) into law, requiring every local government in Florida to allow at least one accessory dwelling unit (ADU) on any lot zoned for single-family residential use. The law, which takes effect on July 1, 2025, overrides local zoning bans and ensures that homeowners statewide can legally build ADUs, also known as granny flats, casitas, or in-law suites, on their properties.

Martin County’s proactive approach to ADU implementation reflects the growing recognition of these structures’ potential. ADUs, sometimes called guest houses or “granny flats,” are secondary, self-contained living spaces on single-family lots, such as backyard cottages, garage apartments, or attached suites. With the county expecting policy implementation before year-end, property owners are already exploring how to capitalize on this opportunity.

The Critical Role of Topographical Surveys in ADU Success

While the regulatory landscape is opening up, successful ADU development hinges on one critical factor: proper site analysis through professional topographical surveying. Industry experts consistently emphasize that skipping this step can lead to costly mistakes and project delays.

Please get a topographic survey. This is so important to avoiding massive issues when you ultimately begin sitework. A planimetric & limited topographic survey will add $2500-$3000 to your project — it’s a cost we actually front for our clients (but they are on the hook for if they end up not building the project). Before we made this step mandatory in our projects, we had to either absorb or pass along up to $20K+ in changes to sitework & foundation costs.

A comprehensive topographical survey provides essential data that directly impacts ADU placement and value maximization. Site Analysis: Before embarking on an ADU project, it’s crucial to assess the site’s suitability and feasibility. Our surveyors conduct a detailed site analysis, provide factors such as lot size, setbacks, access points, and existing utilities.

Maximizing ADU Placement Through Professional Surveying

The strategic placement of an ADU can significantly impact both construction costs and long-term property value. Professional topographical surveys reveal critical information that enables optimal positioning decisions.

We conduct a localized topographic survey to document site elevations, changes, and contours within a 10-foot radius of the proposed ADU footprint. This survey also includes a planimetric analysis to map out existing site improvements, such as structures, driveways, drainage systems, geological features, trees, walls, and fences. This detailed information is crucial for precise planning and ensuring the ADU’s optimal placement on your property.

Utility considerations are equally important for cost-effective ADU development. We conduct a thorough utility mapping process to locate all existing private utilities, including sewer, water, gas, and electric lines, using ground-penetrating radar. By understanding the complete utility layout, we can strategically place your ADU in a location that minimizes the need for significant rerouting or long utility runs, ultimately reducing costs.

The Financial Impact of Proper Survey Planning

The investment in professional topographical surveying pays dividends throughout the ADU development process.

It’s a proactive step that helps avoid costly surprises during construction and ensures that the ADU is designed with a full understanding of the site’s topographical nuances.

ADU construction costs in Florida can vary significantly based on site conditions. The cost of constructing an ADU can vary significantly based on size, location, and design choices. As of 2024, in some areas, a 500 sq ft ADU may range from $150,000 to $250,000, while a 1,200 sq ft ADU could cost between $250,000 to $350,000+. Proper surveying helps optimize these investments by identifying the most cost-effective placement options.
