San Diego sets front, side, and rear yard setbacks separately for each RS residential subzone in Table 131-04D under Municipal Code Section 131.0443, so the minimum distance from a lot line depends on which specific zone applies to the property.
(1) Front Setbacks in RS Zones
For that portion of a lot that fronts a cul-de-sac, the minimum front setback may be reduced 5 feet below the requirement specified in Table 131-04D; however, in no case shall the setback be less than 5 feet.
(2) Rear Setback in the RS-1-1, RS-1-2, RS-1-3, RS-1-4, RS-1-5, RS-1-6, RS-1-7 Zones

Full Breakdown
Required yard setbacks in San Diego's RS zones are not one citywide figure: they are set zone-by-zone in Table 131-04D of the Land Development Code, with Section 131.0443 layering on exceptions. Front setbacks on cul-de-sac lots may be reduced up to 5 feet below the table minimum, but never below 5 feet under Section 131.0443(a)(1). Side setbacks can be reallocated between the two sides of a lot as long as the combined total still meets Table 131-04D, with a reallocated side setback never below 4 feet and a reallocated street side setback never below 10 feet under Section 131.0443(a)(4). Multifamily RM zones and other base zones carry their own separate setback tables.
Violations & Fines
Building within the required setback without an approved deviation triggers code enforcement, can require a Neighborhood or Site Development Permit, and may force removal or relocation of the encroaching structure.
