Room additions, second stories, and primary suites across Los Angeles and the San Fernando Valley — engineered, permitted, and built to look like they were always part of the house.
A home addition through HB Links adds the space you need and ties it into the house so it looks original. Engineering, permits, structure, and finishes — one team, one contract.
Lot survey, setback and floor-area analysis, and a structural review of the existing house before design starts.
Structural engineering, Title 24 energy calcs, and permit review handled with LADBS. No third-party expediter.
New footings, framing, and roof tied into the existing structure. Second stories get the first floor reinforced to carry the load.

FAQ
Answers to the questions homeowners ask most before building a home addition across Los Angeles and the San Fernando Valley.
Answer
It depends on square footage, whether you're building out or up, the foundation and structural work involved, and finish level. Second stories often cost more per square foot than ground-floor additions because the existing structure may need reinforcing. We provide a written estimate after the site and structural review.
Answer
Construction typically runs 3–6 months for a room addition and 5–9 months for a second story, depending on scope. Design, engineering, and permitting come first — we lay out the full schedule before work begins.
Answer
Often, yes. A structural engineer first checks whether the existing foundation and framing can carry the new load — older homes sometimes need foundation upgrades — and we confirm the addition fits LA's floor-area and height limits for your lot.
Answer
An addition expands your existing home — more bedrooms, a bigger kitchen, a primary suite. An ADU is a separate unit with its own entrance, kitchen, and bathroom that you can rent or use for family, and it often benefits from state rules that relax size and setback limits. We'll walk through both options during the consultation.
Answer
Usually, yes. Most of the work happens outside the existing footprint until the tie-in, when there's some disruption where the addition connects. Second-story additions are more disruptive, and some families move out for part of that project. We plan the phases with you up front.
Answer
Yes. Every addition needs a building permit, structural plans, and Title 24 energy compliance. In the City of Los Angeles, plans go through LADBS; Calabasas and other independent cities run their own review. We handle the full submission.
