Medical Retail Space in Lake Forest

What to diligence before LOI

1. 01

   Zoning: the Land Use Matrix in Section 9.72.090 permits Medical Office in the C, I, PA and UA categories. Section 9.04.030 defines it as space for health care professionals providing outpatient services, including medical doctors, walk-in clinics, dentists and chiropractors, with diagnosis, X-ray, laboratory or surgical facilities allowed on site but no overnight care. An Emergency Health Service Facility, which the code treats as a hospital, needs a use permit in C, PA and UA and is prohibited in I.

2. 02

   Parking: Section 9.168.070 parks medical and dental clinics or offices at 1 space per 250 sq ft, the same as general office and lower than the 1 per 200 sq ft required for general retail. On paper a clinic needs fewer spaces than the store it replaces, but a busy urgent care or dental practice can outrun that ratio, so ask the landlord for actual peak-hour counts and any parking or use limits in the center's CC&Rs.

3. 03

   Pharmacy and retail medical: the matrix permits Pharmacy only in C and UA, and Retail Business is accessory only in I (capped at 15% of floor area by footnote 1). A clinic in an industrial or business park building can sell some products, but a retail pharmacy counter needs a C or UA site.

4. 04

   Occupancy change: the 2025 California Building Code lists ambulatory care facilities, outpatient clinics and physician and dentist offices as Group B (Section 304.1), with ambulatory care facilities also subject to Section 422 (Section 304.3), while retail stores are Group M (Section 309.1). Moving a clinic into a former store is a change of occupancy that the Lake Forest Building and Safety Division, (949) 461-3470, will review.

5. 05

   Path of travel and restrooms: Section 11B-202.4 of the 2025 California Building Code requires an accessible path of travel to the altered area, including the primary entrance and the toilet facilities serving it. Under Exception 8, projects at or below the valuation threshold cap that spending at 20% of the adjusted construction cost. Settle in the lease who pays for restroom, entrance and parking-stall upgrades.

6. 06

   Foothill Ranch parcels: the Foothill Ranch Planned Community text (PC 8) sends Commercial land uses to matrix column C but sends parking to the PC's own Section XIX. For a Towne Centre Drive or Portola Parkway suite, confirm with Planning at (949) 461-3535 which parking table applies before you count on the 1 per 250 medical ratio.
