Why Ellery ADU Studio Riverside Is Pedley’s Preferred Garage Conversion ADU Company
We’ve designed, permitted, and built ADUs across Jurupa Valley since its 2011 incorporation, and Pedley’s half-acre lots with their equestrian and light-agricultural roots present a specific set of conditions we know well. Our 900+ ADU projects since 2015 include dozens in the Pedley area, from detached garage conversions off Limonite Avenue to attached conversions near the Santa Ana River corridor.
Pedley clients receive the same documentation we provide everywhere: a written price before work starts, a documented photo record on every visit, and the 365-Day Done Right Promise backed in writing. Our license number appears on every page - verified, not just claimed. Calls are answered by a live person 24/7; no voicemail queue, no callback promise that doesn’t materialize.
What distinguishes our Pedley work is flood zone fluency. Jurupa Valley’s planning counter regularly flags FEMA map verification, and we’ve handled enough Zone AE elevation certificates to know the $500-$1,200 cost is a near-routine line item here that clients from Riverside proper never expect. We price it upfront.
Our Garage Conversion ADU Services in Pedley
Detached Garage Conversion
Pedley’s dominant housing stock - 1950s-1970s ranch homes on oversized lots - often includes detached garages, barns, or shop buildings originally built for agricultural use. These structures are strong conversion candidates, but their age means we almost always find 100-amp electrical service, galvanized supply lines, or cast-iron drains that must be upgraded to meet ADU code. On a 1968 ranch on a half-acre lot off Limonite Avenue, we opened a detached garage for conversion and found exactly this combination, plus termite-damaged south-facing framing. We pulled the Jurupa Valley permit, ordered the elevation certificate for the Zone AE parcel, and priced the panel upgrade, re-pipe, and framing repair as written allowances approved before demolition. The finished unit used a correctly sized mini-split and upgraded glazing to handle 105°F summer highs - and it passed flood-proofing inspection without a second visit.
Attached Garage Conversion
Attached garages in Pedley’s older neighborhoods share the same utility challenges as detached ones, with an added complication: the connection to the main dwelling’s systems. We inspect the shared wall’s fire rating, the existing HVAC capacity, and whether the main panel can absorb a subpanel for the ADU. Many Pedley homes still run on original 100-amp service that cannot support both the main house and a full ADU kitchen, laundry, and HVAC load. Our inspection-first protocol identifies this before demolition, prices the upgrade as a written allowance, and requires your signed approval before we proceed. No door-side upsells, no scope creep - Haven Standard Clause 5.
Carport Conversion
Carport conversions in Pedley face the same flood zone scrutiny as garage conversions, since Jurupa Valley treats any enclosed structure on a foundation as subject to FEMA map verification. Carports also lack existing slabs rated for habitation; we assess whether the existing concrete can be augmented or must be replaced, and we specify insulation and moisture barriers that account for Pedley’s extreme heat and low humidity. The combination accelerates wood framing movement and stucco cracking on south- and west-facing walls, so our specifications include expansion joints and heat-rated exterior finishes.
Garage Partition & Bathroom Add
Some Pedley clients want to retain partial garage function while adding a studio or bathroom - a garage partition with bathroom add. This hybrid approach requires careful Jurupa Valley code review: the remaining garage space must maintain egress and fire separation, and the new bathroom must tie into upgraded drain lines. Original cast-iron drains in Pedley homes are often too corroded to accept new fixtures without replacement. We price this as an inspection-first allowance, with your approval required before we cut into walls.

Trusted Brands We Service in Pedley
We specify and coordinate prefab and modular systems from Abodu, Cover, and Dvele within our single-contract design-build model, and we use James Hardie siding for site-built ADU exteriors where heat resistance and long-term dimensional stability matter. Pedley’s 105°F summer highs and low humidity punish inferior materials; we select for thermal performance and cracking resistance, not just initial cost. Every specification is documented in the permit set, which is the core product of our process - not an afterthought.
Common Garage Conversion ADU Problems We See in Pedley Homes
- FEMA flood zone verification failures. Contractors who pull ADU permits in Pedley regularly get flagged by Jurupa Valley’s planning counter to verify the FEMA flood map panel for the specific parcel. Lots on the south side of surface streets can be in Zone AE while the lot across the street is Zone X, so elevation certificate costs ($500-$1,200) are a near-routine line item that neighboring-city clients never expect to see. We verify the panel during our initial site visit and price the certificate upfront.
- Undersized electrical service. The dominant 1950s-1970s housing stock in Pedley often still carries original 100-amp panels. An ADU with electric range, dryer, water heater, and HVAC can push a 200-amp service to its limit; 100-amp service is non-compliant from the start. We inspect the panel during our first visit and price the upgrade as a written allowance.
- Failed or corroded drain lines. Original galvanized supply lines and cast-iron drains are common in Pedley homes and typically must be replaced to support a new ADU kitchen and bathroom. These lines fail from the inside; visual inspection of fixtures tells you nothing. We include a drain line assessment in our initial inspection and price replacement as an allowance with your pre-approval required.
- Heat-related HVAC and envelope failures. Pedley sits in the Inland Empire heat pocket where summer highs routinely exceed 105°F. An undersized mini-split in a garage conversion will fail within weeks of a July heat wave. We specify Manual J load calculations, correctly sized inverter-driven mini-splits, and low-E glazing with appropriate SHGC ratings for south- and west-facing ADU walls.

Our inspection-first protocol identifies them before demolition and prices repairs as written allowances requiring your approval.
