Summary

Home additions in Buena Park must match the existing roof style and pitch and add enhanced finishes on street-facing and upper-story walls to prevent bulky, out-of-character expansions.

Roofs of new additions shall match the existing roof in style, pitch, and be of unified material. In cases where the existing home has more than one roof style or pitch, the predominant style and pitch of the existing home shall be matched for the proposed addition. Enhanced elevations to include superior finishes, materials, and colors are essential to streetscape appearance and neighborhood compatibility.

Full Breakdown

Buena Park Municipal Code § 19.316.120 functions as the city's anti-mansionization rule for single-family additions. New addition roofs must match the existing roof's style, pitch, and material: where a home already mixes roof styles, the addition must follow the predominant one. Second-story additions require enhanced elevations (stone, brick, siding, window trim, or similar) on all upper-story walls, with both stories enhanced on the street-facing elevation. Second-story windows must be placed to protect neighbors' privacy through offsets, clerestory placement, or obscured glass, and any nonconforming portion of the existing home must be brought into conformance before a building permit issues.

Violations & Fines

Additions that mismatch the existing roofline, skip required elevation enhancements, or add second-story windows without privacy measures can be denied a building permit until brought into compliance.

Frequently Asked Questions

Does Buena Park have a mansionization ordinance?
Yes, § 19.316.120 requires additions to match the home's existing roof style and pitch and adds design and privacy standards for second-story expansions.
Can I add a second story without extra design review?
No: second-story additions need enhanced elevations on all sides and privacy measures for new upper windows facing neighboring yards.
