San Leandro ADU Requirements

Knowing about the San Leandro ADU requirements is crucial before planning and constructing your Accessory Dwelling Unit. In addition, homeowners must follow the guidelines in various State and County Laws. This helps you to get the permits without any delays and hassles.

Although your ADU contractor would handle the permit process, it is still helpful for you to know about some of the essential San Leandro ADU Requirements.

San Leandro ADU Requirements

Number of ADUs allowed

So, as per the San Leandro ADU requirements, how many ADUs can you buid on your property? In accordance with state law, all single-family dwellings are allowed at least one Accessory Dwelling Unit. In addition, single-family owner-occupied lots may create an Accessory Dwelling Unit and a JADU. Additionally, multi-family lots can add one ADU for every four existing residential units as long as they are legally established.

Allowed ADU types

Detached ADU, Attached ADU, and Junior ADU are allowed. It is also important to note that under San Leandro ADU requirements, Accessory Dwelling Units could be brand-new buildings or old spaces that have been renovated. It is necessary to transform existing space to create Junior ADUs.

Lot Size

The underlying zoning district’s minimum lot size and any law for projects including auxiliary dwelling units will not apply to single-family and multi-family residential properties.~ Updated: State Law AB-68.

ADU Size

Residential lots will be approved to create up to 850 square feet for a one-bed ADU or up to 1,000 square feet for a two-bed ADU, regardless of the property’s underlying zoning standards.

According to San Leandro ADU requirements, One Junior Accessory Dwelling Unit up to 500 square feet is approved. In accordance with the California Residential Code, the minimum size of any dwelling unit is 150 square feet (including Accessory Dwelling Units (ADUs) and Junior Accessory Dwelling Units). ~ AB68

Setbacks

Setbacks for a detached new construction Accessory Dwelling Unit must be no more than 4 feet from the rear and side lot lines. Setbacks will not be required for Accessory Dwelling Units and Junior Accessory Dwelling Units converted from existing legally established space.

Attached are new constructions of Accessory Dwelling Units, and conversions of existing space to be expanded must comply with setbacks for the underlying zone. ~ Updated: State Law AB-68

Parking lot

This is an important aspect laid down in San Leandro ADU requirements that people often ignore. Parcels that convert an existing garage to an Accessory Dwelling Unit (ADU) or JADU will not be subject to parking replacement requirements. ~ AB68 and AB881 update

Fire safety

A smoke alarm and carbon monoxide detector will be installed in all ADUs. It shall not be of a higher standard than the principal residence for fire sprinklers.

Fire sprinklers will only be required if they would be required for an equivalent addition or modification of space in a residential property that was not associated with an ADU.

Shape, materials, and style

The ADU maintains scale and is visually compatible with adjoining residences and residences in the immediate vicinity; and its construction materials, shapes (eg, roof pitch), colors, and exterior finishes are compatible with those of the existing home;

Subordinate to existing housing. The ADU shall be visually subservient to the existing home, with an exterior entry made to appear secondary to the existing home entry. If the ADU is on a second story, it must not be accessed by an exterior stairway that is visible from the public right-of-way.

Height

The basic requirements of Article 5 (Residential Neighborhoods) will be applied, except for the following:

  1. Those created through the construction of new habitable spaces on the first floor will be prohibited. However, an ADU made through the conversion of existing livable space above the first floor will be licensed by the Minister if it meets the other design and development standards in this section.
  2. An overlay district may modify the requirements of Article 5.

Design review

An ADU that meets this code’s appropriate location and development standards will be subject to ministerial review and approval. All permits will be issued within one hundred and twenty (120) days of submitting a complete ADU application by the code’s provisions.

Detached ADUs will require ministerial permission on lots larger than seven thousand five hundred (7,500) square feet. On lots measuring seven thousand five hundred (7,500) square feet or less, a Detached ADU may be considered through a Site Plan Review process through the Zoning Compliance Officer.

Residential site plan review

ADUs must adhere to Section 2-580(H)—Standards for Residential Site Plan Review if they are situated in a RO, RS, or RS-40 District and meet the criteria for residential site plan review as specified in this code.

The number of rooms

You might be relieved that the number of rooms is not specified under San Leandro ADU Requirementslaid by the state standards.

Property

Owner occupancy is not necessary for new ADUs (conversion and new construction) between 2020 and 2025. ~ Per SB13

Utility Connections

Public and utility services, including emergency access, are adequate to serve both dwellings.

Permit fees

  1. The City may charge a fee for the costs associated with the issuance of permits and inspections to determine whether the ADU meets the application development and design standards of this section.
  2. ADUs that do not result in a net increase in living space will be exempt from local impact fees. ADUs that add habitable space may be subject to fees commensurate with the proposed ADU’s load on City services. However, under no circumstances can an ADU be considered equivalent to a new single-family dwelling unit for rate calculation purposes.

Definition of ADU under San Leandro ADU Requirements

“Accessory Dwelling Unit” (ADU) means an attached or detached residential dwelling unit that provides complete independent living facilities for one or more persons. An ADU must include permanent provisions for living, sleeping, eating, cooking, and sanitation on the same parcel as the single-family home.

Definition of ADU under San Leandro ADU Requirements

Requirements for Historical Requirements

The ADU is not located on or adjacent to the real property listed on the California Register of Historic Places.

Entry

The entrance must be subordinate to the main entrance of the house.

Street connection

No passage will be required in conjunction with the construction of an ADU unless the Americans mandate such connection with the Disabilities Act or other state or federal safety codes or standards.

Residential Building Code

California Building Code (CBC) 2019 has been adopted.

When constructing your ADU, you must know the rules and regulations you need to follow. Apart from making it easy to get the permits, it also gives you a guideline to start the design and build process.

However, the legal requirements are not the only thing you should focus on. Ensuring proper utility connection, using quality materials, and building a robust structure are also very important. Contact Done Right Home Remodeling today to learn more about San Leandro ADU requirements.
