What you can build here — zoning standards
| Zone(s) | Density | Height | Setbacks F / S / R | Lot coverage | |
|---|---|---|---|---|---|
| Single-family | R-1 Single-Family Residence, and A-1 Light Agricultural — widespread here (suffix = required lot area; both default to R-1-5000 where no number follows) | 1 du/lot; per General Plan H designation | 35 ft (A-1 same, for a single-family residence) | 20' / 5' (10' reversed corner) / 5' / 15' — A-1 yards are identical, but under Table 22.16.050-A, not the residential table | Not set by zone |
| Duplex | R-2 Two-Family Residence | 2 du/lot | 35 ft | 20' / 5' (10' reversed corner) / 5' / 15' | Not set by zone |
| Townhome | R-3 Limited Density Multiple Residence; RPD | Per General Plan H designation | 35 ft | 15' / 5' (7.5' reversed corner) / 5' / 15' | RPD: 30% of net area must be open space |
| Multifamily | R-4 Medium Density; R-5 High Density | R-5 up to 150 du/net acre (implements H100/H150) | R-4 13 × buildable area; R-5 65 ft — but stepped back to 45 ft at a common lot line with R-1/R-2, then 1 ft recess per additional ft | R-3/R-4 15' / 5' / 5' (R-4 adds 1 ft per story above two, max 16') / 15'; R-5 5' front, 15' side if adjacent to R-1/R-2 or 0' if separated by a 15 ft+ right-of-way | Not set by zone |
Parking · No parking required at all inside a defined public transit area (§ 22.112.070.A). Outside one — SFR 2 covered; two-family 3 covered + 1 covered/uncovered; apartments of 10 units or fewer 1/du regardless of bedrooms; larger apartments 1/du bachelor, 1.5/du efficiency + 1-bd, 2/du two-bd and up, plus 1 guest space per 10 du at 11+ units; senior/disabled housing 0.5/du + 1 guest per 8 du; JADUs none.
Overlays to check · Rowland Heights Community Standards District — now **§ 22.366.090**, folded into the East San Gabriel Valley PASD (Ch 22.366, Ord. 2024-0029). The old standalone Ch 22.332 no longer exists. Its residential provisions are narrow (recreational-vehicle parking on R-zoned lots, etc.) and do not replace the base Title 22 table above; its lot-coverage and setback rules (80% coverage / 20% landscaping; 20 ft along Fullerton, Colima, Nogales, Fairway and Brea Canyon Cut-Off, 15 ft elsewhere) apply to **commercial and mixed-use** frontages. Also: PASD area-wide significant-ridgeline protection (§ 22.366.060) · Southwest Puente Setback District (§ 22.366.100) · Density Bonus (Ch 22.120) · Inclusionary Housing (Ch 22.121) · Housing Permits (Ch 22.166) · SB 9 lot-split eligible
Base zoning — always check for a project-specific overlay or density-bonus increase. Not legal advice. LA County Code Title 22 — § 22.18.010–.060 (residential zones), Table 22.18.040-A (yards), § 22.16.050 + Table 22.16.050-A (A-1 agricultural yards/height), § 22.18.040.D (height), Ch 22.110 (general site regulations), Table 22.112.070-A (parking), Ch 22.366 (East SGV PASD, Ord. 2024-0029), § 22.366.090 (Rowland Heights CSD).
