Full Breakdown
Section 240-8.4JJ of the Unified Development Ordinance defines a secondary dwelling unit as a complete, separate detached dwelling with its own cooking and sanitary facilities and its own entrance. It is allowed only on lots that meet two-family-dwelling standards where the sole principal building is a single-family home, and only where Table 8-A lists the use. One of the two units must be occupied by the property owner, and no more than one secondary unit is permitted per lot. The unit's footprint cannot exceed 60% of the primary dwelling's footprint or 1,000 square feet, whichever is less, and its front building line must sit 10 feet behind the principal structure. The Building Department enforces it.
Violations & Fines
Building an attached in-law apartment, adding a second unit inside the single-family house, exceeding the 60%/1,000-square-foot footprint cap, or renting both units without the owner living on-site violates § 240-8.4JJ.
