In recent years, homeowners have increasingly looked to their garages as prime real estate for conversion into additional living space. Whether it's to accommodate a growing family, create a rental income opportunity, or simply add a home office, garage conversions offer both financial and lifestyle benefits. However, one of the most common questions that arise is whether converting a garage requires the creation of new parking spaces. This post explores the legal, practical, and creative aspects of this question, helping homeowners make informed decisions.

Converting Your Garage

Converting a garage into a livable space involves several considerations, from insulation and wiring to plumbing and flooring. For DIY enthusiasts, this can be an exciting project, but it's important to know when to bring in professionals, especially for electrical and plumbing work. Planning your conversion with these factors in mind ensures a smooth transition from a garage to a comfortable living space.

The Parking Dilemma Solved for Garage Conversions

One of the biggest potential roadblocks when considering a garage conversion is dealing with the loss of parking spaces. However, there are several solutions that can help mitigate or eliminate this issue altogether.

In many urban and suburban areas, local zoning laws are becoming more friendly towards reducing parking requirements, especially for properties located near public transit hubs or in neighborhoods with ample street parking. The rationale is that reducing parking minimums encourages use of alternative transportation modes and reduces paved surfaces. If your property falls into this category, you may not need to create additional parking at all.

When parking must be replaced, the existing driveway is often the easiest solution. Most single-family home driveways can accommodate at least one parking space if properly sized and surfaced according to local regulations. Typical requirements are:

- Minimum width of 8-10 feet

- Minimum length of 18-20 feet

- An all-weather, dustless surface like concrete, asphalt, pavers, etc.

By converting the garage interior into living space and utilizing the driveway for parking, you regain all that square footage without losing parking capacity.

In cases where the driveway is too small or regulations require more parking, options like front yard parking pads, tandem parking in a lengthened driveway, or applying for street parking permits may be available. The key is carefully reviewing your local zoning ordinances and required parking minimums based on your property's location and proposed changes.

With some creative thinking and knowledge of the rules, that converted garage can become amazingly usable space without an onerous parking headache to overcome.

Understanding ADU Parking Regulations Across the States

California: A Leader in ADU Legislation

California's progressive stance on ADUs is designed to alleviate the housing crisis by making it easier for homeowners to create additional living spaces. According to the state's 2020 laws:

  • Parking: One of the most homeowner-friendly aspects is that off-street parking is not required for ADUs if certain conditions are met. This means you can convert your garage into an ADU without the need to replace the lost parking spaces.
  • Size and Zoning: ADUs in California can be as small as 150 square feet, with attached ADUs limited to 50% of the primary dwelling or up to 1,200 square feet.

Washington: Localized Flexibility

Washington State offers a more localized approach to ADU regulations, offering flexibility but requiring homeowners to check with their local jurisdictions. Some common threads include:

  • Proximity to Transit: Many areas do not require off-street parking for ADUs if they are within a quarter mile of a major transit stop, echoing a broader move towards reducing car dependency.

Oregon: Local Jurisdiction with Statewide Support

Similar to Washington, Oregon allows for ADU development with local jurisdictions setting specific rules. However, the state encourages the construction of ADUs by:

  • Size Limits and Parking: Offering a range of size limits and leaving parking requirements to local jurisdictions. This approach offers customization but requires homeowners to perform due diligence with their specific locality.

Georgia: Guided by Model Ordinance

Georgia approaches ADU regulations with a model ordinance, providing a framework for local jurisdictions. Key aspects include:

  • Parking Requirement: Unlike California, Georgia's model ordinance requires one off-street parking space for the ADU, unless it's close to transit. This reflects a balance between creating more housing and managing parking needs.

Understanding these regulations is the first step in planning your garage conversion, ensuring your project aligns with local laws and avoids potential legal headaches down the road.

Parking Space Solutions

For homeowners concerned about losing their garage parking, there are several creative solutions to explore:

  • Driveway Extensions: Expanding your driveway can compensate for the lost garage space, allowing for off-street parking without a garage.
  • Carports: A simpler, cost-effective alternative to building a new garage, carports provide covered parking and can be designed to complement your home's aesthetics.
  • Shared Parking Agreements: In areas where off-street parking is scarce, arranging shared parking with neighbors or nearby businesses can be a mutually beneficial solution.

Parking Exemption Saves $15K for CA ADU

Just a while ago, we saved one of our clients over $15,000 by ensuring they didn't have to provide additional off-street parking for their new ADU in Los Angeles.

Like many cities, Los Angeles used to require homeowners to add expensive paved parking spaces when building an accessory dwelling unit. However, new state laws that went into effect in 2020 prohibited cities from imposing certain parking requirements related to ADUs.

Specifically, the updated regulations stated that parking cannot be required for ADUs if they meet any of the following criteria:

- The ADU is within a half-mile walking distance of public transit

- The ADU is part of an existing primary residence or an existing accessory structure

- On-street parking permits are required but not offered to the ADU occupant

- There is a car share vehicle pick-up/drop-off location within one block

Our client's property met two of those exemption criteria - it was close to a bus line, and the ADU was being created from an existing detached garage. Despite this, the city planning department originally insisted they would need to construct a new off-street parking spot, at a cost of around $15,000 for paving and landscaping.

However, we cited the specific sections of the new state ADU laws that prohibited enforcing such a parking requirement in this situation. After pushing back with the updated code references, the city planners acknowledged they had missed those recent exemptions.

As a result, our client avoided having to spend $15,000 on unnecessary parking spot construction. Being well-versed in the evolving ADU legislation saved them a substantial amount of money.

This highlights how important it is to work with professionals who truly understand the latest laws and advocate for a homeowner's rights related to these types of construction projects. The rules are constantly changing, so you need experts in your corner.

The Takeaway

Converting a garage into an ADU can be a smart move to add value to your property and address housing needs. While the thought of navigating zoning and parking regulations might seem daunting, the current trend across states like California, Washington, Oregon, and Georgia is leaning towards making this process more accessible for homeowners.

Remember, each state — and often each locality within that state — has its nuances. Therefore, it’s essential to start your ADU project by researching and understanding these regulations to ensure compliance and make the most out of your conversion project. Whether you're a DIY enthusiast or planning to hire professionals, being informed is your first step towards successfully expanding your home's potential.
