ADU Building in Miami Shores, FL

As of 2024, Florida's new ADU law (SB 250) significantly eases restrictions on Accessory Dwelling Units. It requires local governments to allow ADUs on properties zoned for single-family residential use, provided they meet certain size and safety standards. This law aims to increase affordable housing options. For homeowners in Miami, Miami Beach, and Hialeah, this means you can typically add an ADU up to 800 square feet or 50% of the main home's living area, whichever is less, without onerous owner-occupancy requirements. However, local zoning ordinances still apply, so it is crucial to check with your municipality.

Trusst Construction recommends consulting a professional to ensure full compliance.

For homeowners seeking the most affordable Accessory Dwelling Unit, the cheapest option is typically a detached, prefabricated or modular unit. These are built off-site in a controlled factory environment, which significantly reduces labor costs and construction time. A smaller studio or one-bedroom layout, often under 600 square feet, will also keep expenses lower. While a garage conversion can be cost-effective, it often requires extensive structural modifications and upgrades to meet current building codes, which can add unexpected expenses.

At Trusst Construction, we emphasize that the cheapest initial build is not always the most cost-effective long-term, as quality and energy efficiency must be factored into your budget.

When building an ADU, common mistakes include underestimating the total project cost, which often ignores utility connections, impact fees, and design expenses. Another frequent error is failing to verify local zoning rules, such as setbacks, height limits, and parking requirements, leading to costly redesigns. Homeowners also overlook the need for separate utility meters or proper fire safety separations between the main house and the ADU. Poor planning for construction access and material storage on tight lots can cause delays. Additionally, skipping a professional site survey often results in boundary line violations. For a comprehensive breakdown of these issues and more, please refer to our internal article ADU Construction in Miami-Dade County: The Most Complete Zoning, Permitting, and Turnkey Cost Guide for 2026. Trusst Construction recommends consulting with a local expert early to avoid these pitfalls.
