ADU Plans in San Dimas
San Dimas sits at the eastern edge of the San Gabriel Valley with a mix of residential and equestrian-zoned properties. We’ve completed projects in San Dimas including ADUs, room additions, and custom home designs. Some properties here have unique zoning designations — including equestrian overlays — that affect what can be built and where.
Why San Dimas Clients Work With Us
We handle the zoning research, setback analysis, and full construction document preparation for San Dimas projects. Our familiarity with the city’s specific requirements means fewer surprises during plan check.
With over 1,500 residential and commercial projects completed across Los Angeles County in the last decade, we bring a depth of experience that most firms can’t match. We don’t just know the California building code — we know how San Dimas’s building department applies it.
Some San Dimas properties carry equestrian overlay zoning that affects setbacks, accessory structures, and site planning.
