Perris has the largest untapped JADU market of any city we serve — the city's 1990s–2010s housing stock is full of attached 2-car garages on homes that were never converted because homeowners didn't know the option existed. Converting an attached garage to a JADU in Perris costs $25,000–$60,000 and generates $950–$1,300/month — one of the strongest yield ratios in Southern California. If you haven't had a JADU assessment, you may be sitting on 2–5 year payback income potential that requires no new construction footprint.
Perris's JADU Pipeline — The 1990s–2010s Garage Opportunity
Perris was built out primarily in the 1990s through 2010s — newer housing stock than Hemet, older than some Chino Hills neighborhoods, and overwhelmingly standard attached-garage suburban floor plans. The typical Perris 3BR or 4BR home has a 440–560 sf attached 2-car garage oriented to the front or side of the home. This is the most common JADU conversion type in California — and Perris's housing stock has it in abundance.
What makes these garages good JADU candidates:
- They're already attached to the primary structure (required for JADU under §66333)
- Standard dimensions (22×20 ft or 20×20 ft) fit a functional efficiency or 1-room layout
- Plumbing can often be extended from the adjacent garage-hall bathroom with short runs
- Electrical panel upgrades from the original construction are typically adequate
- Exterior door opening to the side or rear yard provides independent access
JADU vs. New Detached ADU in Perris
| Factor | JADU (Perris) | New Detached ADU |
|---|---|---|
| Build cost | $25,000–$60,000 | $135,000–$195,000 |
| Monthly rent | $950–$1,300 | $1,500–$2,000 |
| Payback period | 2–5 years | 7–12 years |
| Flood zone impact | Typically none — existing structure | May require elevated foundation |
| Perris permit path | Pre-approved plan eligible | Pre-approved plan eligible |
For Perris homeowners on flood zone lots, the JADU has an additional advantage: converting space within the existing structure avoids the new elevated foundation construction requirement that a new detached ADU would trigger. The JADU uses the existing foundation — which is already compliant or grandfathered. This can save $8,000–$20,000 on flood zone lots.
Owner-Occupancy Requirement
California §66333 requires the property owner to live in either the JADU or the primary dwelling. For homeowners who live on the property, this is no constraint. For absentee landlords or investors, JADUs are not available — a full detached ADU (no owner-occupancy requirement per AB 976, 2024) is required.
