Free Second Opinion on Any Written ADU Estimate
Already have a written estimate for a garage conversion, detached ADU, or JADU from another Pomona contractor? We’ll review it line by line and tell you where the numbers land and what questions to ask next. No obligation, no pressure to switch.
Valid through December 31, 2026. Mention this offer when you call (657) 286-7915.
Written Price Guarantee - No Estimate Fees, Ever
Under Haven Standard Clause 1, every Pomona ADU project receives a written, line-item price before any work starts. That isn’t a special, it’s our standard, but most studios charge for permit feasibility or charge again when the design changes. We don’t.

365-Day Done Right Promise - Locked In Writing
If your finished ADU in Pomona isn’t built to the permitted drawings, we make it right. This isn’t a verbal handshake; it’s a written warranty signed before construction begins, covering workmanship and code compliance for a full year after final inspection.
Valid through December 31, 2026. Mention this offer when you call (657) 286-7915.
Documented Photo Record on Every Site Visit
Every crew visit to your Pomona property includes dated, geotagged photos of what was found and what was done. You receive the record, not a summary of how it felt. This helps with lender draws, city inspections, and resale documentation.

Questions about your Pomona ADU permit status at 9 PM? A real person picks up. No callback promise that doesn’t materialize, no automated menu. This matters when your city inspector requests a revision and you need clarity before the morning.

Looking at Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, or James Hardie for your Pomona ADU? We specify and coordinate these systems under the same one-contract design-build model, so the designer and builder can’t point at each other when something is off.

What These Offers Actually Cover
We’ve been designing, permitting, and building ADUs in Pomona and across Los Angeles County since 2015. In that time, we’ve completed over 900 ADUs, and every single one started with a written price and ended with a documented photo record. These aren’t introductory gimmicks for new customers; they’re the same terms we apply to repeat clients and referrals.
Pomona’s ADU market has specific variables that affect pricing. The city’s zoning overlay in the downtown core allows smaller setbacks than the hillside districts north of Foothill Boulevard. Soil conditions near Ganesha Park differ from the compacted fill common in redevelopment areas south of the 10 freeway. Our estimates account for these local factors, not generic square-footage multipliers.
We pull permits through Pomona Building & Safety and coordinate with Los Angeles County when your property sits near unincorporated pockets. Our permit sets include Title 24 energy calculations, structural wet stamps, and landscape plans where required. You receive copies of every submittal, not just the approval notice.

No. Under Haven Standard Clause 5 (No Surprises), the scope locks at signing. If you request changes, we write a change order with a new price before any additional work begins. No door-side upsells, no scope creep. Call (657) 286-7915 for an exact quote - estimates are free.
Garage conversions in Pomona usually move fastest, often 6 to 10 months depending on Planning review cycles and whether your property needs a sewer lateral upgrade. New detached ADUs typically run 10 to 14 months. We build realistic timelines into your written estimate, not optimistic ones.
