Glendale ADU cost guide — every line, no surprises
A fixed-price Glendale ADU contract is the sum of five line items: base build, City of Glendale Community Development permits and fees, design and engineering, sitework and utilities, and finishes. Below is how each one moves in Glendale specifically — and where homeowners get burned by quotes that hide them.

Base build — what $/sqft actually covers
Base build in Glendale runs $385–$520 per square foot for a detached one-bedroom ADU at 2026 pricing. That number assumes Title 24 compliance, code-minimum insulation, mid-grade finishes, and standard MEP. Anything below $360/sqft in Glendale is either skipping permits, skipping engineering, or carrying allowance line-items that will balloon during construction.
City of Glendale Community Development fees & soft costs
Glendale plan-check, school fees, sewer capacity, water meter, and utility connection fees typically land between $14,000 and $28,000. The variance is driven by lot conditions: a flat Glendale lot on existing sewer is the low end; a hillside lot needing a new lateral and water tap is the high end. We pull these numbers at feasibility, not after deposit.
Design, engineering, and soils
Architectural design, structural engineering, Title 24 compliance, and (when Glendale requires it) a geotechnical report typically run 8–11% of project cost. Hillside-zoned parcels and properties within special review overlays push this higher. We disclose the engineering scope up front so the design fee isn't a moving target.
Sitework, utilities, and the hidden 15%
Sitework in Glendale — demolition, grading, retaining if needed, sewer tie-in, water service upgrade, electrical panel upgrade to 200A — is where most "cheap" quotes blow up. Older Glendale homes nearly always need a panel upgrade and often a lateral upgrade. Budget 12–18% of project cost here. We scope this at survey, before contract.
Finishes — the only line you actually control
Finish allowances (cabinets, counters, flooring, fixtures, appliances) are the single line a Glendale homeowner can move materially up or down. Going from builder-grade to mid-luxe adds roughly $35–$60 per square foot. Going to luxury finishes can add $90+/sqft. We model three finish tiers at design so the trade-off is visible, not buried.
