ADU & Home Additions in Burlingame: FAQ
Answers to common questions from Burlingame homeowners.
Under California state law, you can build a detached ADU up to 1,200 sq ft on most Burlingame lots. A Junior ADU (up to 500 sq ft) within your existing home is also permitted in addition to the detached unit. The city's Design Review process focuses on appearance and neighborhood compatibility, not restricting state-mandated ADU rights.
Standard ADU permits in Burlingame follow California's 60-day review timeline. Projects that trigger Design Review add 4-6 weeks. With design, engineering, and construction, the total timeline from initial consultation to move-in is typically 12-16 months. Pre-approved San Mateo County ADU plans can reduce the design phase.
Detached ADUs under 800 sq ft that comply with state standards are generally exempt from Design Review. Larger ADUs, second-story additions, and projects that significantly alter the streetscape may require Design Review. Barcci Builders prepares comprehensive applications — elevations, material boards, 3D renderings — that facilitate smooth approvals.
A 1-bedroom ADU in Burlingame rents for approximately $2,800-$4,000/month given the city's premium location, walkable downtown, and excellent schools. A 2-bedroom unit can command $3,500-$5,000/month. This is among the highest ADU rental rates on the Peninsula, making the investment particularly attractive.
Yes. Second-story additions are common in Burlingame, particularly for single-story homes in Lyon-Hoag and Ray Park where families need more bedrooms. The city evaluates height, massing, and neighbor impact through its Design Review process. We design additions that complement your home's architecture and neighborhood context, maximizing approval odds and property value.
A well-designed, architecturally compatible ADU in Burlingame can add $250,000-$500,000+ in property value. Burlingame buyers prize flexibility — guest quarters, home offices, rental income potential — and a quality ADU delivers all three. The key is building something that looks and feels like it belongs on the property, not a prefab afterthought.
