As the demand for additional living space increases, homeowners seek cost-effective and practical solutions. Garage conversions and ADUs offer the potential to transform underutilized spaces into functional living areas. While both options serve a similar purpose, they differ in several aspects. Let’s delve into the details.

What are Garage Conversions?

A garage conversion involves converting an existing garage into a livable space that can be used as a bedroom, office, gym, or even a rental unit. By repurposing the garage, homeowners can effectively utilize the available square footage within their property.

Benefits of Garage Conversions

Cost-effective: Garage conversions are generally more affordable than building an entirely new structure.

Quick turnaround: Converting a garage into a living space can often be completed in a shorter time frame compared to constructing an ADU.

Existing infrastructure: Garages already have essential utilities like electricity and plumbing, reducing the need for extensive installation.

Flexible usage: Garage conversions offer versatility, allowing homeowners to tailor the space to their specific needs.

Considerations for Garage Conversions

Permits and regulations: Homeowners must ensure they obtain the necessary permits and comply with local regulations before converting their garage.

Parking alternatives: Converting a garage may require alternative parking solutions, as the dedicated garage space will no longer be available.

Space limitations: Garages are generally smaller compared to ADUs, so homeowners must consider the available space and its suitability for their intended use.

What are ADUs?

Accessory Dwelling Units, commonly known as ADUs, are standalone structures that can be constructed on the same property as the main house. ADUs are self-contained living spaces with their own entrance, kitchen, bathroom, and living area.

Benefits of ADUs

Increased property value: Adding an ADU can significantly enhance the value of the property.

Rental income: Homeowners can generate additional income by renting out the ADU as a long-term or short-term rental.

Separate living space: ADUs provide privacy and independence for family members or tenants.

Multigenerational living: ADUs are ideal for accommodating elderly parents or adult children while maintaining separate living arrangements.

Considerations for ADUs

Construction process: Building an ADU involves construction work, which may require permits and approvals. Homeowners should consider the associated time and cost.

Design and aesthetics: ADUs need to blend harmoniously with the main house and the neighborhood’s architectural style.

Infrastructure requirements: Additional utilities, such as plumbing, electricity, and water supply, need to be extended to the ADU during construction.

Comparison of Garage Conversions and ADUs

Construction Process: Garage conversions involve renovating an existing garage, while ADUs require new construction.

Cost: Garage conversions are generally more affordable compared to ADUs, which involve higher construction costs.

Available Space: Garage conversions have limited space since they repurpose an existing garage. ADUs offer greater space as they are standalone structures.

Rental Potential: ADUs have a higher rental potential due to their separate structure, while garage conversions may have limited rental options.

Independence: Garage conversions are part of the main property, while ADUs provide separate living spaces with their own entrance, enhancing independence.

Value Addition: ADUs contribute significantly to the property’s value, while garage conversions have a more moderate impact.

Parking Arrangements: Garage conversions may require changes to parking arrangements, while ADUs often have separate parking spaces.

Privacy: ADUs provide a higher level of privacy as they are separate structures, while garage conversions share the property with the main house.

Design Flexibility: ADUs offer greater design flexibility as they are new constructions, while garage conversions have limitations based on the existing garage structure.

Factors to Consider when Choosing between Garage Conversions and ADUs

When deciding between a garage conversion and an ADU, several factors come into play:

Budget: Assess your financial resources and determine which option aligns with your budgetary constraints.

Space Requirements: Consider the amount of space needed for your intended use and whether a garage conversion can fulfill those requirements.

Rental Income: If rental income is a priority, ADUs generally offer more potential for generating revenue.

Property Value: Evaluate the potential impact on your property’s value, as well as the long-term benefits of each option.

Regulations: Research local zoning regulations and permit requirements to ensure compliance with the relevant authorities.


In conclusion, both garage conversions and ADUs provide homeowners with valuable options to expand their living spaces. Garage conversions offer affordability, flexibility, and quicker turnaround times, while ADUs provide greater independence, rental income potential, and property value enhancement. When choosing between these options, carefully evaluate your budget, space requirements, and long-term goals to make an informed decision.
