Jurisdiction: City of San Diego. Del Mar Heights is not part of the City of Del Mar. Permits run through San Diego’s Development Services Department.
Where Del Mar Heights sits
The City of San Diego’s Torrey Pines Community Plan area is bounded by Interstate 5, the City of Del Mar, Solana Beach, and the University community, and includes Crest Canyon. The City describes the area’s character in terms of sandstone bluffs, canyons, and open space. Del Mar Heights appears to fall within that plan area; we’ve inferred this from the boundaries and a local fire safe council plan, so confirm on the City’s community plan map.
The housing
ZIP 92014, which covers the City of Del Mar and adjacent City of San Diego areas including Del Mar Heights, has a median year built of 1975, with about 68 percent of units predating 1980 (Census estimates). Those figures blend both jurisdictions, so we treat them as a general guide. Many Del Mar Heights homes appear to date from the 1960s and 1970s, though we haven’t verified eras street by street.
What canyon-edge lots bring
- Slopes. Homes on the edge of a canyon can have a raised downhill side, stepped footings, tall stem or cripple walls, and decks built out over the slope.
- Fill. Pads graded for mid-century construction may include fill on the canyon side.
- Drainage. Water from the street and uphill lots crosses the property toward the canyon. Where it concentrates, it can soften soil at foundations and load retaining walls.
- Retaining walls. Common at grade changes, driveways, and yards. See retaining wall repair.
- Fire awareness. Crest Canyon is mapped as a very high fire hazard severity zone in the City of Del Mar’s plans. Owners nearby think about defensible space, which can interact with landscape irrigation and slope planting.
What we evaluate
- Crack patterns and whether they widen toward the canyon.
- Floor elevations and any trend toward the downhill side.
- Downhill foundations, piers, and cripple-wall bracing.
- Deck footings, which often receive less attention than the house.
- Drainage paths and discharge points relative to the slope.
What a repair can include
- Supplemental piers or underpinning on the downhill side, designed by an engineer.
- Grade beams to tie foundation elements together.
- Cripple-wall bracing and anchorage. See seismic retrofit.
- Drainage corrections that intercept water before it reaches the house or the slope. See foundation drainage.
- Retaining wall repair or replacement.
We coordinate with licensed engineers as needed, and slope work typically begins with a geotechnical report.
City of San Diego rules
- Repairs and alterations to regulated structures require a building permit unless exempt under the Municipal Code (§129.0202).
- Fill and expansive soil can trigger geotechnical reporting for small residential foundations (Information Bulletin 141). The City’s Seismic Safety Study maps hazard categories that also inform review.
- Parcels near the coast or bluffs may be in the Coastal Overlay Zone, where a coastal development permit may be required (§126.0704; Information Bulletin 402). Check your parcel.
For bluff and hillside homes inside the City of Del Mar, the rules differ. See bluff and hillside homes.
Owner questions
Our mail says Del Mar. Why do City of San Diego rules apply?
Mailing names follow postal routes, not city limits. Del Mar Heights is within the City of San Diego.
Our deck is separating from the house. Where do we start?
With both the deck footings and the house foundation on that side. Either can be the cause.
A previous owner enclosed the space under the house. Does that matter?
It can. Finished or enclosed space under a raised downhill side may hide posts, bracing, and drainage. We look for an access point and note anything we could not see.
Does your work change with fire season?
We keep drainage and slope recommendations compatible with defensible-space practices and avoid adding irrigation on slopes.
