Murrieta Home Additions
Murrieta home additions are typically driven by family growth, multi-generational living, or the need to create dedicated home-office space. BPP designs and builds them as integrated extensions, not bolted-on rooms — structural engineering, foundation work, and finishes that match the existing home.
Murrieta Home Additions for Inland Empire Families
Home additions are the highest-investment scope BPP Construction handles, and Murrieta is one of our most-requested markets for them. The reason is demographic: Murrieta families tend to put down roots, raise children here, and stay long-term, which makes adding 400-1,200 square feet to a home more economical than relocating to a bigger house in a different neighborhood. Our additions span master suite additions, great-room expansions, second-story builds, ADU construction, and dedicated home-office wings.
Every Murrieta addition starts with the same first step: an in-home consultation with Ben Pickering. We measure the existing footprint, understand how your family lives in the current space, and identify what is missing. Sometimes the answer is a 350 sq ft master suite addition that becomes the new primary bedroom; sometimes it is a 700 sq ft great-room that opens to the backyard; sometimes it is a detached ADU that becomes Grandma’s place or a long-term rental. We design with you, not at you.
Murrieta additions require coordination with the City of Murrieta for permits, structural engineering for foundation and load paths, possibly HOA approval depending on the neighborhood (Copper Canyon, California Oaks, and Murrieta Hot Springs all have HOA review processes). BPP manages all of it. Our 35-year track record across Riverside County means we know which inspectors look for what, which engineers turn around stamped drawings fastest, and how to keep your project on schedule despite the multi-stakeholder coordination.
How Home Additions Works for Murrieta Properties
Master Suite Additions
A 300-600 sq ft master suite addition is the most-requested Murrieta home-addition scope. Typical setup: bedroom (14×16 or larger), private full bathroom with walk-in shower, walk-in closet, sometimes a private office or sitting area. Construction runs 4-6 months. Cost band $120,000-$240,000 depending on finishes and connection complexity to existing structure.
Great-Room Extensions
A 400-800 sq ft great-room addition opens to the backyard, integrates with the existing kitchen, and becomes the new heart of the home. Vaulted ceilings, large windows, indoor-outdoor flow with sliding glass doors. 5-7 months. Cost $160,000-$320,000. Ideal for entertaining-focused Murrieta families.
ADUs and Detached Buildings
California ADU laws make detached secondary units more permissible than ever. We build 400-1,200 sq ft ADUs for multi-generational living, long-term rental income, or work-from-home dedicated spaces. Cost $150,000-$350,000 for full ADU including foundation, framing, mechanicals, and finishes.

How long does a Murrieta home addition take?
Master suite addition (300-600 sqft): 4-6 months. Great-room addition (400-800 sqft): 5-7 months. Second-story addition: 6-9 months. ADU construction: 5-8 months. Permits + engineering add 2-4 weeks before any ground-breaking.
What does a Murrieta home addition cost?
Master suite: $120,000-$240,000. Great-room: $160,000-$320,000. ADU: $150,000-$350,000. Second-story addition: $250,000-$450,000+. BPP gives line-itemed quotes after the in-home consultation. Costs scale with square footage, finish level, and structural complexity.
Do I need an architect or do you handle design?
For most Murrieta additions, we coordinate with a local architect for stamped drawings (typically 8-12% of construction cost). For simple master suite additions on standard footprints, Ben can sometimes handle design directly. We tell you which path applies on the consultation.
Will my Murrieta HOA approve the addition?
Most Murrieta HOAs have an architectural review process. We have submitted dozens of additions to Copper Canyon, California Oaks, and Murrieta Hot Springs HOAs and know what each board looks for. Approval typically takes 4-8 weeks and is part of the timeline we plan around.
Can I stay in the home during construction?
Almost always yes. Additions are mostly exterior construction during the first 2-3 months (foundation, framing, roofing, exterior finish). The interior connection happens last and is the only time the existing home feels disrupted. We seal off work areas with plastic and minimize household impact.
Do you handle ADU permits?
Yes. California ADU laws make permitting straightforward, but Murrieta still requires plan review, site setbacks, utility connections, and often utility upgrades. We manage the full process and report back at every milestone.
