In Perris's working-family tenant market, the 1BR at 650 sf and the 2BR at 850 sf are both strong performers — driven by the I-215 logistics corridor tenant pool that includes working couples and small families who specifically want 2-bedroom space. The 750 sf impact fee exemption saves $6,000–$12,000 in Perris. The flood zone consideration: if your lot is in a FEMA flood zone, elevated foundation requirements add $8,000–$20,000 regardless of ADU size — making the size decision less cost-sensitive but the flood zone factor more important.
Perris Lot Sizes and Coverage
Perris's 1990s–2010s housing stock sits primarily on 6,000–9,000 sf lots — similar to Temecula's planned community lots but with less HOA coverage. City of Perris imposes a 40% lot coverage limit. On a typical 7,500 sf Perris lot with a 1,600 sf home footprint:
- Total allowed coverage: 7,500 × 0.40 = 3,000 sf
- Existing home footprint: 1,600 sf
- Available for ADU footprint: 1,400 sf — more than enough for any ADU size
State law overrides local coverage limits with a minimum 800 sf ADU regardless of lot coverage math. In practice, Perris's newer housing stock with its larger footprints still leaves adequate remaining coverage for a 650–900 sf ADU on most lots.

| 800–900 sf | 2BR | $1,900–$2,400/mo | $165,000–$220,000 | 13.8–16.1% |

Why 2-Bedrooms Perform Well in Perris
Perris's logistics corridor tenant pool includes a higher proportion of families with children than Temecula's military/professional market or Norco's equestrian market. Working families specifically seek 2BR units for the second bedroom — a child's room, a home office, or a room for a family member contributing to rent. In Perris, the 2BR at $1,900–$2,400/month leases as quickly as 1BR units and produces a $400–$600/month premium. On a $35,000–$50,000 additional construction investment, the 2BR payback on the size upgrade runs 5–9 years.
The JADU Opportunity in Perris's 1990s–2010s Stock
Perris's housing stock — newer than Hemet's and more uniform than Norco's — contains a strong JADU pipeline. 3BR and 4BR homes built in the 1990s through 2010s with attached 2-car garages are the most common floor plan type in newer Perris developments. The attached 2-car garage at 440–550 sf with a rear-facing orientation makes a viable JADU for $25,000–$55,000 — a fraction of new construction cost for a 2BR detached ADU.
Your lot, your flood zone status, and your income target together determine the optimal Perris ADU size. We work through this at the free consultation.
