Under La Habra Municipal Code 18.12.070, fence and wall heights in residential zones are measured from the highest grade at the wall's location, which governs how a fence combined with a retaining wall is measured.

La Habra requires a building permit before installing or constructing any swimming pool, spa, or hot tub. Plans are submitted through the city's online portal and reviewed by the Building & Safety Division against California Building, Plumbing, Mechanical, and Electrical Codes.

La Habra applies the same permit, enclosure, and safety rules to above-ground pools as to in-ground pools. Where the pool wall itself serves as the barrier, extra provisions govern ladder access and the mounted enclosure height.

Beyond the enclosure, La Habra pools must include at least two of seven state-approved drowning-prevention safety features under the 2025 CRC and California SB 442. Options include isolation fencing, ASTM safety covers, exit alarms, self-closing self-latching doors, and pool alarms.

La Habra permits accessory dwelling units and junior ADUs ministerially with only a building permit under LHMC Section 18.12.150 (Ordinance 1835), implementing California ADU law. No owner-occupancy is required for standard ADUs and no parking is mandated.

La Habra allows converting an existing garage into habitable living space primarily through its ADU ordinance (LHMC 18.12.150). A building permit is required, converting a garage without permits is a code violation, and demolished garage parking need not be replaced when the space becomes an ADU.
