The ADU Builder Hollywood Hills Homeowners Trust
Hollywood Hills lots are steep, narrow and full of character, which makes ADU projects here very different from flat-lot builds.

We are a licensed, insured, family-owned design-build team. One crew handles design, engineering, permits and construction, with a free in-home consultation, honest pricing, a schedule we keep and a written warranty on every ADU.

Hillside Rules Every Hollywood Hills ADU Faces
Hollywood Hills is in the City of Los Angeles, but nearly every lot here falls under special hillside and fire rules. An experienced ADU builder Hollywood Hills owners hire will check these first:
- Baseline Hillside Ordinance: Grading limits tied to slope, plus hillside height, setback and floor area rules.
- Very High Fire Hazard Severity Zone: Most of the area requires fire-hardened construction, and fire sprinklers may be needed.
- Narrow hillside streets: Lots on substandard streets can face extra limits on new ADUs, so street width is checked early.
- Geology and soils: Steep lots usually need geotechnical reports and deeper foundations before plans are approved.
- Longer plan check: Hillside review takes longer than flat lots, so we build that time into your schedule.

ADU Builder Hollywood Hills FAQs
Why hire a local ADU builder Hollywood Hills homeowners recommend?
Hillside lots involve grading limits, fire zone rules, street access checks and heavy engineering. A builder who knows these steps can tell you early what is possible and keep the project on track.
Can I build an ADU on a steep Hollywood Hills lot?
Often, yes. Many owners build above or beside the garage or step the ADU into the slope. We review your lot, street and soils to find the best option.
Does street width affect my ADU?
It can. Lots on narrow hillside streets may face extra limits on new ADUs under city rules. Garage conversions and JADUs are sometimes easier paths, so we check your street early.
What fire safety rules apply in the Hollywood Hills?
Most of the area is a Very High Fire Hazard Severity Zone, so ADUs need fire-hardened construction such as Class A roofing and ember-resistant vents, and sprinklers may be required.
Why do hillside ADUs cost more?
Steep lots often need caissons, retaining walls and soils engineering, and materials are harder to get on site. Those costs depend more on the slope than on the size of the ADU.
How long does a Hollywood Hills ADU take?
Hillside projects usually take about 6 to 10 months for engineering and permits, then 6 to 10 months to build, depending on the site.
