Woodland Hills room additions benefit from the neighborhood’s best feature: space. With lot sizes frequently ranging from 8,000–20,000+ sq ft in the flat areas and larger on the hillside, Woodland Hills homeowners have more room to add than virtually anywhere else in the west Valley. Combined with home values of $1.8M–$4M+, this creates excellent conditions for primary suite additions, multi-room additions, and second story projects that would be constrained on smaller lots in Sherman Oaks or Studio City. APLA Construction (CA Lic #1136359) handles room additions throughout Woodland Hills, managing all LADBS permits, soils engineering for hillside properties, and all construction trades.
What you get: Single bedroom addition, 150–250 sq ft. Foundation, framing, roofline extension, electrical, insulation, drywall, flooring, windows, and finishes. LADBS plan check and permit.
Best for: Woodland Hills homes at $1.5M–$2M needing a bedroom count increase without bathroom changes.
What you get: Primary bedroom (180–285 sq ft) with attached primary bathroom (65–115 sq ft) and walk-in closet. In Woodland Hills, primary suite additions on large flat lots are often the most straightforward additions in the Valley — generous rear yards, flat terrain, and conventional ranch-style homes that tie additions in easily. Full MEP and finishes.
Best for: Woodland Hills homes at $1.8M–$3M where the primary suite is the defining resale limitation.
What you get: Woodland Hills’s large lots enable larger additions than most Valley communities. 900–1,400 sq ft of new finished space — primary suite, additional bedroom, family room or bonus room. This is a Woodland Hills-specific scope that is simply not feasible on the smaller lots of Sherman Oaks or Studio City.
What you get: Second story above an existing Woodland Hills ranch home, approximately doubling square footage to 3,200–4,800 sq ft. Woodland Hills’s larger homes (1,800–2,800 sq ft single-story) produce particularly large second stories at resale values that support the investment strongly.
Properties in Woodland Hills above Mulholland Drive and in the Woodland Hills Estates area involve hillside construction. Hillside additions require soils reports ($3,500–$8,000), potential grading permits, and hillside-specific structural engineering. APLA evaluates hillside requirements for every Woodland Hills addition project before design begins — at no cost.
Bedroom only: $88,000–$158,000. Primary suite: $172,000–$308,000. Large multi-room 900–1,400 sq ft: $400,000–$620,000. Second story: $360,000–$640,000+. Woodland Hills costs are comparable to Encino and slightly below Sherman Oaks for equivalent scopes.
Yes. Woodland Hills’s larger lot sizes — many properties at 9,000–20,000+ sq ft — enable larger additions while maintaining setback compliance. An addition scope that would consume most of the available rear yard in Sherman Oaks leaves substantial garden remaining in Woodland Hills.
Bedroom only: 4–7 months. Primary suite: 5–9 months. Large multi-room: 7–12 months. Second story: 9–16 months. LADBS Van Nuys office (serves Woodland Hills): plan check 5–9 weeks for structural additions. Hillside properties: add 4–8 weeks for soils review.
