Understanding Whole House Generators

Before diving into the placement details, it’s essential to understand what a whole house generator is and how it functions.

What is a Whole House Generator?

A whole house generator, also known as a standby generator, is a permanent fixture that provides power to your entire home during electrical outages. It automatically kicks in when the power goes down, ensuring continuous electricity supply.

How it Differs from Portable Generators

Unlike portable generators, whole house generators are larger, have a higher power capacity, and are permanently installed outside the home. They are directly connected to the home’s electrical system and require professional installation.

Key Factors in Generator Placement

Several critical factors influence where a whole house generator should be installed. These include safety regulations, noise considerations, and accessibility for maintenance.

Adhering to Safety Regulations

Safety codes and regulations, such as maintaining a certain distance from windows and doors, dictate generator placement to minimize risks like carbon monoxide poisoning.

Noise Level Considerations

Generators can be noisy when operating. Placement should consider minimizing disturbance to household members and neighbors.

Accessibility for Maintenance

Easy access to the generator is essential for regular maintenance and repairs. The location should be convenient for technicians to perform servicing.

Site Selection Criteria for Generators

Choosing the right site for a generator involves several criteria that ensure optimal operation and adherence to regulations.

Distance from the House

Generators should be installed close enough for efficient operation but far enough to comply with safety codes and reduce noise impact inside the home.

Level Ground and Drainage

The site should be on level ground for stability and have proper drainage to prevent water accumulation around the generator.


Good ventilation is crucial for the generator’s operation and to prevent overheating. The location should allow for free air circulation around the unit.

Installation Considerations

Proper installation is key to the generator’s performance and longevity. It involves more than just placing the generator in the right spot.

Professional Installation

Hiring a professional for installation ensures that the generator is correctly set up, connected, and complies with all local codes and standards.

Preparing the Site

Site preparation might involve constructing a concrete pad for the generator to sit on and ensuring that the ground is properly graded and drained.

Legal and Compliance Aspects

Adhering to local laws and regulations is critical when installing a whole house generator. This includes obtaining necessary permits and ensuring the installation meets all local building and electrical codes.

Permit Requirements

In many areas, installing a whole house generator requires a permit. Check with your local municipality for specific requirements.

Compliance with Local Codes

The installation must comply with local building and electrical codes, which may dictate specifics regarding placement, noise control, and safety measures.
