Accessory Dwelling Units (ADUs), colloquially known as tertiary lodgings, annex apartments, or bungalows, are supplementary living spaces incorporated into pre-existing or newly-constructed residential edifices. This initiative is pertinent to both singular and collective abodes. Within this composition, we shall expound upon the method of procuring the requisite authorization for appending an ADU to a pre-existing, detached dwelling.

Potential ADU positions include: 1. Within the extant structure. 2. As a contiguous augmentation to the prevailing building. 3. Or as an autonomous formation, sharing the same parcel of land as the primary domicile. ADU dimensions: 1. not exceeding 50% of the principal habitation 2. limited to a 16 ft elevation (on an inclined terrain, the altitude may deviate) 3. internal areas must adhere to the construction bureau's stipulations. ADU or Non-ADU?

Initially, ascertain if your estate qualifies for ADU San Francisco. Procure this data within your Enhanced Value or Novel Abode dossier. Fortuitously, you might be among the privileged ones deemed Suitable for ADU.

Is It Waiver or Non-Waiver?

The municipality of San Francisco provides a leeway for deviations from the prevailing regulations. Those of you for whom the extant edifice permits an ADU under contemporary code stipulations are termed "NO Waiver" ADU. Conversely, those necessitating certain dispensations from the code are labeled "Waiver" ADU. Determine whether you pertain to "NO Waiver" or "Waiver" ADU here.

Categories of ADUs

Four distinct ADU classes exist:

1.      Conversion ADUs - novel units transforming areas within residential construction.

2.      Adjoined ADUs - innovative units augmenting a residential edifice.

3.      Unattached ADUs - unprecedented autonomous structures situated on residential land.

4.      Junior ADUs (JADU) - a fresh ADU variety transmuting up to 500 sq. ft. of space in a single-dwelling framework. SADU mandates proprietor occupancy in either the residual single-family residence segment or the newly established SADU.
