A. Density requirements for residential care facilities for older persons.

(1) Density for residential care facilities for older persons shall be calculated in terms of the number of beds for permanent use. The initial bedroom in each independent living unit and the initial bed in each assisted or personal care unit shall count as one bed, and each additional bedroom in that independent living unit or bed in that assisted or personal care unit shall count as 0.6 of a bed. An "efficiency" or "studio" type independent living unit shall count as one bed. Each assisted or personal care bedroom shall be deemed an assisted or personal care unit. For each intermediate care unit and each skilled care unit, density shall be based on actual beds. The number of beds provided in intermediate care and skilled care unit shall not constitute more than 25% of the total number of beds in the residential care facility.
(2) The total allowable number of beds for the residential care facility shall be calculated on the basis of lot area, as defined in § 208-6: Definitions; word usage, and the type of underlying zoning district. Density in mixed residential/nonresidential districts shall be based on the residential use(s) permitted in that district.

(a) Single-family detached: eight beds times the number of single-family dwellings allowed per acre.
(b) Single-family semidetached and two-family semidetached, single-family attached and multifamily or apartment: 2,900 square feet of lot area per bed.
(c) Nonresidential districts: maximum density of 30 beds per acre.

(3) Any proposed permanent change to the ratio of the types of units provided in a residential care facility shall constitute a modification of the conditional use requiring a new conditional use approval upon application to the Board of Supervisors.
