How This Guide Helps Florida Community Associations
- Accurate occupancy data supports energy savings, safety, lease compliance, and 55+ age-restricted documentation for Florida communities.
- Occupancy sensors detect people who are sitting still, while motion sensors often miss them and create false vacancy readings.
- mmWave radar and thermal sensors provide strong stationary detection with a privacy posture that fits Florida regulations.
- Physical sensor data solves only the building-systems layer; communities still need centralized, real-time lease visibility for compliance and audits.
- TenantEvaluation’s Lease Tracking platform connects occupancy confirmation with real-time lease status visibility inside one connected system.
Occupancy Sensors vs. Motion Sensors: Key Differences
Motion and occupancy sensors sound similar, but they solve different problems. A motion sensor reports whether something moved within its detection field. An occupancy sensor reports whether a space is occupied, which matters most when people are sitting still.
A plain PIR motion sensor cannot reliably detect a stationary person because a motionless person becomes invisible to it within seconds, producing what practitioners call a “ghost vacancy.” The sensor signals empty when the space is not. An occupancy sensor using technologies beyond PIR supports utilization analytics and real-time presence data for HVAC scheduling, cleaning, space consolidation, and lease negotiations, while motion sensors only produce binary signals based on recent movement.
For Florida community associations, this distinction affects lease compliance and 55+ documentation. A system that produces false vacancy readings cannot reliably confirm unit occupancy for board records or age-restricted audits. If your association needs to connect occupancy confirmation to lease compliance tracking, see how TenantEvaluation’s Lease Tracking delivers real-time lease status visibility inside one platform.
Six Main Types of Occupancy Tracking Sensors
The comparison below evaluates six sensor technologies across three decision points for residential compliance use. These are stationary occupant detection, privacy posture under Florida law, and realistic 2026 deployment cost per unit. All cost figures reflect 2026 market data.
Real-world performance of occupancy sensors often depends on installation and placement rather than the core technology. Dual-technology sensors that combine PIR with ultrasonic or acoustic sensing improve detection reliability in spaces where occupants remain relatively still for extended periods, reducing both false-on and false-off events compared to single-technology sensors. Having established which technologies detect stationary occupants most reliably, the next filter for Florida associations is privacy compliance.
Privacy Rules That Shape Sensor Choices in Florida
Florida law sets clear limits on what occupancy sensors can capture in residential settings. Under the Florida Security of Communications Act (Fla. Stat. Chapter 934), intentional interception of any wire, oral, or electronic communication without the consent of all parties is prohibited, making Florida an all-party consent state for audio and creating consent and wiretapping risk for any occupancy tracking sensors that capture conversations in residential or HOA settings.
The Florida Information Protection Act (FIPA, Fla. Stat. 501.171) requires covered entities to implement reasonable measures to protect personal information, including biometric records when combined with other identifiers, and to notify affected individuals after a breach. This requirement reaches any biometric data collected by occupancy tracking sensors in Florida residential properties.
For most Florida community associations, the Florida Digital Bill of Rights primarily applies its core controller obligations to for-profit businesses exceeding $1 billion in global gross annual revenue (and meeting additional criteria), while certain provisions such as the sensitive-data-sale consent rule reach all for-profit businesses regardless of revenue. Contract terms, vendor disclosures, and internal policies remain the main compliance tools.
Non-imaging sensor approaches carry the strongest privacy posture for residential deployments. Privacy-preserving occupancy sensors such as thermal devices capture only numerical outputs like occupancy counts and traffic flow without ever generating images, device IDs, or personally identifiable information at any point in the data pipeline. This approach simplifies compliance and reduces liability exposure for associations.
BACnet and Building System Integration for CAMs and Boards
Integrating occupancy data with existing building systems helps communities turn sensor readings into lower energy use and better comfort. BACnet is a leading protocol in North American BAS deployments and supports multi-vendor integration of occupancy sensors, lighting controls, and HVAC equipment from manufacturers including Tridium, Siemens, Johnson Controls, Honeywell, and Schneider. For CAMs and boards, BACnet/IP compatibility usually serves as the baseline requirement for connecting occupancy data to current BAS infrastructure.
Occupancy sensor platforms publish real-time room-level counts directly into Building Automation Systems via BACnet/IP or API, allowing the BAS to treat occupancy as a standard input point for demand-controlled ventilation, vacant-room temperature setback, and lighting control. This connection turns raw presence data into measurable operating savings.
Key factors CAMs and boards must evaluate before committing to a sensor platform include:
- Protocol compatibility: BACnet/IP, MQTT, REST API, or proprietary gateway requirements
- Wireless vs. wired deployment: wireless occupancy sensors using LoRaWAN, Zigbee, or Wi-Fi 6 can be installed on existing HVAC equipment in hours without cabling or electrical modifications, making them suitable for 2026 retrofits
- Data latency: reporting intervals that support timely HVAC and lighting response
- Vendor lock-in risk: open API platforms that reduce dependence on a single vendor
- Ongoing maintenance: battery replacement cycles for large fleets of sensors
These integration and maintenance factors feed directly into the broader decision framework for Florida associations, which connects technical choices to compliance and workload outcomes.
Decision Framework: Matching Sensors to Association Priorities
Florida community associations evaluating occupancy tracking solutions should weight four criteria against their specific operational context. These criteria translate the technical sensor comparison into day-to-day outcomes for CAMs and boards.
- Compliance readiness: The sensor technology must avoid audio capture, fit within Florida’s privacy statutes, and produce documentation suitable for board records and potential audits.
- Operational efficiency: The system should reduce manual follow-up, integrate with existing building systems, and deliver data in a format CAMs can act on without extra processing.
- Auditability: Occupancy records need timestamps, searchability, and retention policies that support dispute resolution or regulatory review.
- Scalability: The solution should expand across a portfolio without proportional increases in administrative burden or hardware cost.
Applying these criteria, mmWave radar and thermal sensors often fit Florida associations best. They meet compliance needs by avoiding imaging and audio, support operational efficiency through reliable stationary detection, provide audit-ready timestamped counts, and scale across communities without constant privacy review of video feeds. Camera-based systems can deliver higher raw accuracy but introduce privacy complexity that many associations will struggle to manage in dwelling-adjacent spaces.

Common Lease and Occupancy Pain Points in Florida HOAs and Condos
Physical sensor data addresses only one dimension of the occupancy challenge. For most Florida community associations, the more immediate operational problem is that lease records are disconnected from occupancy confirmation entirely. Common pain points include:
- Missing or outdated lease copies stored across folders, inboxes, and spreadsheets
- Manual lease expiration tracking with no automated alerts
- No centralized visibility into which units have active, pending, expired, or missing leases
- No direct connection between the application and approval process and active lease records
- Difficulty producing audit-ready documentation for 55+ compliance reviews or board decisions
These gaps create operational blind spots that slow teams and increase the risk of compliance issues and resident disputes. They persist even when communities invest in modern sensor infrastructure.
Lease Tracking: Centralized Real-Time Lease Visibility and Lifecycle Control
Lease Tracking provides a centralized operational capability inside TenantEvaluation that connects resident onboarding, unit data, approvals, and lease documentation in one audit-ready workflow. It replaces spreadsheets and scattered email chains so every lease stays connected, searchable, trackable, and ready for review from application through occupancy.
For CAMs, property managers, and community operations teams, Lease Tracking delivers:
- Real-time lease status visibility at the unit level, including active, pending, expired, or missing leases
- Automated lease document collection during the onboarding process

Frequently Asked Questions
What are the three types of occupant detection system sensors?
Occupant detection systems generally fall into three functional categories. Passive sensors, primarily PIR, detect changes in infrared energy from moving bodies without emitting any signal. Active sensors, including ultrasonic and microwave or mmWave radar, emit a signal and measure changes in the reflected return, which allows detection of subtle movements like breathing even when an occupant is stationary. Imaging and network-based sensors, including camera-based computer vision and Wi-Fi or Bluetooth tracking, use visual or device-signal data to infer occupancy. These approaches can offer higher accuracy in some scenarios but introduce greater privacy complexity. Many modern deployments combine two categories in dual-technology configurations to reduce false vacancy readings.
What is the difference between a motion sensor and an occupancy sensor?
A motion sensor detects movement and stops registering once movement ceases. A person sitting still at a desk, reading, or on a call will typically become invisible to a basic PIR motion sensor within seconds of stopping movement, which triggers a false vacancy signal. An occupancy sensor is designed to determine whether a space is occupied regardless of movement level. It uses technologies such as mmWave radar, thermal sensing, or time-of-flight depth sensing that detect the physical presence of a body rather than its motion. For Florida community associations, this distinction matters when occupancy confirmation must support lease documentation or board decisions instead of simply controlling a light switch.
How much do occupancy sensors cost in 2026?
Hardware costs range from approximately $15 to $40 for basic residential PIR sensors and $50 to $200 for commercial-grade ceiling-mounted PIR or dual-technology units. mmWave or advanced presence sensors typically start at $229 per device. Professional installation adds roughly $100 to $500 per device depending on ceiling height and cable runs. For analytics-grade systems, recurring cloud software subscriptions usually run $20 to $100 per sensor per month, and support plans add 8 to 12 percent of hardware value annually. Software costs often exceed hardware costs by year three. Total first-year costs for a 3D stereo people-counting system range from approximately $1,200 to $3,940 per sensor including hardware, installation, software, and support. Many organizations recover these costs within 6 to 12 months through energy efficiency and labor savings.
What is the best occupancy sensor for stationary occupants?
For stationary occupant detection, review the comparison table above and focus on how each technology detects presence. The key difference is whether the sensor detects presence, such as body heat or micro-movements like breathing, or only motion, such as limb displacement. mmWave and thermal sensors detect presence, while PIR primarily detects motion. For Florida associations, this difference determines whether the sensor can support lease compliance documentation or only control building systems.
Conclusion: Connecting Occupancy Data to Lease Compliance
Choosing an occupancy tracking sensor requires matching capabilities such as stationary accuracy, privacy posture, BACnet integration, and total cost of ownership to the realities of a Florida community association. Presence-focused, non-imaging approaches like mmWave radar and thermal sensing often provide the strongest mix of accuracy and privacy for residential deployments. PIR sensors still work well for high-traffic transient spaces but do not reliably confirm ongoing occupancy for seated residents.
Physical sensor data, however, addresses only the building-systems layer of the occupancy challenge. The lease management layer, which includes missing documents, manual expiration tracking, disconnected records, and no real-time status visibility, calls for a dedicated operational platform. Lease Tracking inside TenantEvaluation delivers centralized, real-time lease visibility and lifecycle control, connecting resident onboarding, unit data, approvals, and lease documentation in one audit-ready workflow that replaces spreadsheets and scattered email chains.
Florida CAMs and boards that evaluate their current lease visibility gaps against the criteria in this guide will see that a centralized platform extends operational and compliance benefits far beyond what any sensor deployment alone can provide. See how TenantEvaluation’s Lease Tracking replaces spreadsheets and email chains with one audit-ready platform, from application to occupancy.
