5 Questions to Ask Before Converting Detached Garage Into Apartment

Turning a garage into an accessory dwelling unit (adu) is the best option for you if you fit the following criteria so you do not have to start from scratch and save on costs. The criteria include

  • The garage door can easily be replaced: Your new living space should allow for patio doors or an additional entrance to replace the former overhead door. If this is not possible, make sure the new wall would fit the current home design and transform the wall so that it would make it more like a new room than an old garage.
  • You can afford heating and cooling: To save money, find out if your HVAC system can support another room. If it can, you can easily save by expanding the system to the additional room. If it can’t, you have no other choice but to upgrade the system or you can buy a new system that is specifically for the garage to provide heat and cool solutions.
  • Plumbing is accessible (if needed): If you’re planning to have an additional bathroom or kitchenette to convert your project more of an in-law suite or apartment, you better call the plumber to add plumbing lines to add drainages which is the most important and may be the most expensive part of the garage project.
  • You still have adequate parking and storage: Transforming your garage means removing your sparking and storage space. Turn a garage into an extra space only if it would be a great investment where you still have other places to place your machines, equipment, and automobiles.
  1. Is a Permit Required to Convert a Garage?

When transforming your garage space into a 1 bedroom ADU or 2 bedroom ADU in Los Angeles, you would need to acquire a building permit depending on your location. In order to apply for a conversion permit, contact your city’s Zoning Department for more information. An architect might be needed to give you proposed floor plans in applying for a permit.

A proper permit will make sure you meet your building codes and local ordinances for living spaces. Building codes would dictate your limits in your construction project as it would only allow for a minimum number of windows in a given space, the number of exits and entrances required, the height of the ceiling as well as the number of outlets and safety hazards. If you do not meet all these requirements, you could apply for a variance if you have a different issue.

These permit costs vary from state to state but more often, it would cost you between $1,000 and $1,500 unless you have to pay more when applying for a variance. Be informed that some city ordinances or homeowner associations may require a certain amount of covered parking which can hinder you from transforming your garage.

The result of the transformation is also a factor in how much the added value would be and what type of room you build. Usually, you could expect the value added to be 80% of the project cost. 

On the other hand, there are also factors that can affect the worth of your transformed garage such as:

  • If your neighborhood requires covered parking or limited street parking. If you do not have a garage, it would make parking an issue which can drive down the cost of sale.
  • If the project is done illegally or without permits, permits can actually help increase the project’s value in the long run.
  • If you do not have storage, this will be a major problem for it would only make things worse and which can make the sale price become smaller.
