While facing the current housing crisis in California, ADUs (Accessory Dwelling Units) have become recognized as the most creative way to provide affordable units for housing property owners. For example, although ADUs, the most common of which are garage conversions, are widespread, they cannot be permitted and hence are “illegal” operations that pose legal challenges for homeowners. This post will enlighten you on the steps to take to legalize ADUs.

Understanding the Issue To Legalize ADU

After determining the rules for illegal ADU, it is imperative to understand what exactly an illegal ADU is. Consequently, non-issuance of required permits and certificates of occupancy makes an ADU illegal. Sometimes, unpermitted constructions are seen as the easier way. Still, they are some of the most dangerous ways as they compromise safety only to create trouble with the law eventually.

Why Legalize ADUs?

The effort of California to legalize ADUs is in line with the housing crisis relief they are capable of causing. On top of that, legal ADUs allow those who don’t own a house to have a safe and secure place to live and help address the state’s daunting affordability challenges. On the other hand, homeowners are subject to regulations within their regions to attain compliance and safety standards.

Process To Legalize ADU

Step 1: Investigate the present ADU unit

To legalize ADU, you must start reviewing your ADU status by examining the available opportunities and potential barriers. Awareness of local zoning laws and building codes is the main guiding rule in acknowledging regions that need development. Teamwork with zoning specialists who are experienced in local law completion enables a smooth process while meeting building and safety regulations.

Step 2: Conceptualize Plans for Modifications

Shortcomings should then serve as the basis for planning out the needed corrections. This process is expedited through collaboration with well-rooted ADU designers, which makes approving these projects much quicker.

Step 3: Prepare and Send Plans to the Authority for Approval

Provide the final plans to the city authorities for implementation and be keen to use the unit legalization programs in case they are available. While applying for a permit, comply with location standards and other safety measures. Access to an experienced ADU designer or contractor with whom the officials can communicate smoothly cuts down the project’s approval process.

Step 4: Start Construction

Now armed with approved plans, move on to the construction to legalize ADU. The choice of well-respected contractors familiar with ADU buildup is a critical factor in ensuring the on-time and budget-friendly delivery of the project. The experienced contractor has approval plans in mind and can deliver on time without extra costs, which one was unaware of.

Step 5: Schedule Inspections

The next step to legalize ADU is to schedule the inspections periodically to ensure all the building codes and safety standards are followed. City inspectors of different departments are conducting a feasibility study on electric systems, plumbing, and structure issues. Although it may mean making some changes after the inspection, these inspections ensure the ADU meets all the compliance standards.
