Room Addition in Atwater Village, CA — Costs, Permits and Contractor Guide (2026)

Atwater Village’s post-war and mid-century bungalows — typically 1,100–1,600 sq ft on relatively flat 5,000–7,000 sq ft lots — are well-suited to room additions. With no hillside complexity, no Coastal Zone overlay, and standard LADBS jurisdiction, Atwater Village is actually one of the more straightforward neighborhoods in Northeast LA for addition permitting. APLA Construction (CA Lic #1136359) has built room additions throughout Atwater Village, delivering the additional space homeowners need without the cost and disruption of moving.

Room Addition Costs in Atwater Village (2026)

Single-Story Rear Addition ($85,000–$165,000)

Size: 200–400 sq ft. Typical scope: new bedroom, home office, family room, or nursery added to the rear of an existing bungalow or ranch house. New slab or raised foundation, new framing, new roofline matching existing, integration with existing interior. Matching exterior siding or stucco. LADBS permit with structural engineer plans. Most common Atwater Village room addition type given the neighborhood’s relatively flat lots.

Primary Suite Addition ($110,000–$220,000)

Size: 350–600 sq ft. New primary bedroom with walk-in closet and full ensuite bathroom. Significant plumbing rough-in to the addition. Frequently combined with a primary bathroom expansion for homeowners who want a full primary suite. This is the highest-value addition type for Atwater Village homes, as most original bungalows lack a true primary suite.

Second Story Addition ($185,000–$365,000)

Size: 500–1,200 sq ft of new second-floor living space. Adds one or two bedrooms, a bathroom, and potentially a home office or bonus room above the existing first floor. Requires full structural engineering, reinforcement of existing bearing walls and foundation, and complete interior staircase integration. For Atwater Village homeowners on lots where rear-yard space is limited, a second story is the only way to significantly expand.
