SAN DIMAS CUSTOM HOME BUILDER & GENERAL CONTRACTOR
Built With Intention. Foothill Views Preserved.
SAN DIMAS HOMES ARE BUILT DIFFERENTLY
Heart Construction is a general contractor serving San Dimas, specializing in custom homes, full renovations, and foothill lots and fire-hardened hillside homes. We work with homeowners, architects, engineers and designers on every project, through organized pre-construction, transparent budgeting and steady execution, so you stay in control of decisions.
Here, the mountains shape the rulebook.
Hillside and fire-zone lots go through the City of San Dimas Building and Safety plan check, with Planning, Public Works and LA County Fire sign-offs. Fire-zone construction standards, fuel modification, soils and grading all come before a permit issues. We lay that sequence out first.
Large additions trigger soils reports, several city departments review each plan set, and school fees apply to new habitable space. Settling scope early keeps those triggers from surprising you, and it protects your schedule.
We guide the process so every decision feels informed, not reactive, from first feasibility review to final inspection.
From full remodels of 1960s–80s homes to ADUs, garage conversions and hillside custom rebuilds, we bring the same structure and discipline we apply across the San Gabriel Valley and every project in Los Angeles.

What to Know Before
You Build in San Dimas
Multi-department review sets the pace in San Dimas, where the City of San Dimas Building and Safety plan check coordinates with Planning, Public Works and LA County Fire. Routine permits take 3–6 months; hillside or fire-zone projects, and anything needing design review, run 6–12 months. Construction for a custom home takes 10–16 months. The lever that protects your schedule is making scope, soils and fuel modification decisions early, before design is final.
What It Costs
Costs here reflect 1960s–80s homes, hillside and soils work, and fire-hardening, against a median home value around $800K. Custom homes typically run $500–$750+ per sq ft; whole-home renovations $325–$600+ per sq ft; detached ADUs $250,000–$450,000+; pools $120,000–$300,000+. Soft costs — design, soils and geotechnical studies, permits — are additional. You receive a line-by-line budget before construction begins.
Permits, Rules & Fire Codes
Your project starts with the City of San Dimas Building and Safety plan check, with Planning review alongside. Hillside lots add the single-family hillside zone standards, soils and grading approvals, and fuel modification approval from LA County Fire. ADUs follow the city's ADU chapter. Fire-zone construction standards and residential sprinklers are our base specification, not upgrades. We sequence all of this from feasibility into one coordinated submittal, so design decisions are made with the constraints known.
Where We Build in San Dimas
Cienega Valley Estates, Chester Oak Estates, San Dimas Royal, Via Verde, Mesa Oaks, Cedar Creek, San Dimas Canyon, Old Town San Dimas, across flat streets and foothill slopes near Way Hill and Rhoads Park.

A feasibility review answers that in two to four weeks.

Frequently Asked Questions
About Renovation in San Dimas
Do I need a permit in San Dimas?
Yes. Additions and remodels need plan check from the City of San Dimas Building and Safety Division, with Planning review. Plans must meet zoning, setbacks, height and lot-coverage limits before a permit issues. Fire-zone lots may also need sign-offs from Public Works and LA County Fire. We prepare one coordinated submittal.
How long does a permit take?
Routine permits run 3–6 months through the City of San Dimas plan check; complex hillside or design-review projects run 6–12 months. Construction for a custom home takes 10–16 months. Settling scope and soils decisions before design is final protects your schedule. See our custom home build timeline for each phase.
Cost to build a home in San Dimas?
Custom homes typically run $500–$750+ per sq ft. Hillside grading, soils work, fire-hardening and finish level push projects toward the upper end. Soft costs — design, soils studies, permits and school fees — are additional. You receive a line-by-line budget before construction begins.
What do hillside lots require?
Hillside lots fall under the single-family hillside zone, Chapter 18.32, which requires development to blend with the natural setting, with street and emergency-access standards. Fire-zone lots must meet CRC R337, and LA County Fire requires Fuel Modification Plan approval before a permit. New homes and additions over 50% of floor area need a soils report.
Are you licensed and insured?
Yes. Heart Construction holds California Contractors State License Board license #1146456 and is bonded and insured for large-scale residential construction, major remodels and structural work. You can verify the license on the CSLB website.
