Local Details Every ADU Builder West Hills Project Checks

West Hills has a few details that set it apart from the rest of the Valley:

  • Permit history under two names: West Hills was part of Canoga Park until 1987, so older permits and plans may be filed under Canoga Park. We search both names before design starts.
  • Ranch homes from the 1960s and 1970s: Many homes have original electrical service and sewer lines that may need upgrades to support an ADU.
  • Equestrian streets: Lots near Valley Circle Boulevard may sit in horsekeeping areas, so we place the ADU around corrals and trails.
  • Hillside and fire zones: Homes near the Simi Hills can fall in fire hazard zones that call for fire-rated roofing and ember-resistant vents.
  • Large flat lots: Many properties have room for a detached ADU of up to 1,200 square feet plus a JADU.

ADU Builder West Hills FAQs

How much does an ADU builder West Hills project cost?

Garage conversions and JADUs usually run about $90,000 to $150,000. Detached ADUs typically range from about $180,000 to $350,000 or more, depending on size, site work and finishes.

Why do my property records say Canoga Park?

West Hills was part of Canoga Park until 1987, so older permits and plans may use that name. We search records under both names.

Will my 1960s ranch home need upgrades for an ADU?

Often, yes. Older homes may need a larger electrical service or sewer work, which we include in your estimate.

Can I build an ADU on an equestrian lot?

Usually, yes. We place the ADU so corrals and trail access still work, and we check any horsekeeping rules for your lot.

Who issues ADU permits in West Hills?

West Hills is part of the City of Los Angeles, so permits go through LADBS. We handle the filings, plan check and inspections for you.

Can I rent out my West Hills ADU?

Yes. Long-term rentals of 30 days or more are allowed. Short-term rentals are generally not allowed for ADUs in Los Angeles.
