San Marino jumbo loans and 2026 loan limits.

San Marino was incorporated in 1913. Huntington Drive, a wide boulevard with a planted center strip, crosses the city from west to east and holds most of its shops. Pasadena is to the north, South Pasadena to the west, and Alhambra and San Gabriel to the south. The Huntington Library, Art Museum and Botanical Gardens occupy a large estate in the northern part of the city, and Lacy Park, a city park of lawns, old trees and walking loops, is nearby. The Old Mill, an adobe grist mill from the mission era, stands on a street to the west.

The city is entirely residential apart from its shopping streets, and nearly every home is a detached house. North of Huntington Drive the lots are large and the houses are mostly from the 1920s through the 1940s, in English, Spanish, French and American Colonial styles, along with newer houses. South of the boulevard lots are smaller, with many houses from those same decades. The ground is level or gently rolling, and the streets are lined with mature trees.

Mainly the appraisal and the age of the house, because the other usual questions seldom arise here.

Condominiums are all but absent, so there is seldom an association to review, and almost no homes pay association dues. The city lies below the foothills, so wildfire is less often the question it is in the foothill cities to the north, though the state’s fire hazard map is still worth checking for the address. That leaves the house. An appraiser compares it with recent sales of similar size, age and lot. On the largest properties north of Huntington Drive those can be few, and a lender may order a second appraisal on a larger loan.

Older houses bring an insurer’s questions about wiring, plumbing, roofs and foundations, and a policy must be in place for a loan to close. Ask what has been replaced.

The city has detailed rules on design, on the size of a house for its lot, and on removing trees, and it reviews plans closely. A buyer who means to rebuild should learn what is allowed first. A permitted accessory dwelling unit is counted by an appraiser, and the property remains one unit for the loan limit.

This is the northern part of San Marino, around the grounds of the Huntington Library and its gardens. Oxford Road, Orlando Road and Euston Road run beside or close to the estate, and the Pasadena line is a short distance north, with the Oak Knoll neighborhood beyond the city’s northwestern edge.

Here are the city’s largest lots, many well over half an acre, with houses set far back behind lawns and old oaks. Most date from the 1920s through the 1940s and were designed individually, and some properties include a guest house, a pool house or a tennis court. Each is one of a kind, which is the difficulty in an appraisal. The appraiser needs sales of comparable scale, and in a small city there may be only a few in a year, so the search can reach into nearby parts of Pasadena. Plan for the appraisal to take longer and for a second one on a large loan. Buildings on the lot count toward value when they have permits. Large old houses may hold early wiring and plumbing behind well-kept walls, so read the inspection carefully.

Lacy Park lies in the western part of San Marino, north of Huntington Drive, entered from Virginia Road. It was once a small lake, known as Wilson Lake, and is now a broad lawn ringed by trees and walking paths. The streets around it include Virginia Road, St. Albans Road and Monterey Road, and City Hall is on Huntington Drive, some way to the east.

Homes near the park are two-story houses on lots that are generous without being estates, most built between the 1920s and the 1940s, with a number of later rebuilds. For a lender this is a fairly even group of houses, which helps: an appraiser can usually find recent nearby sales of similar size. What varies is condition. One house may have new systems, a new kitchen and a permitted addition, and its neighbor may be close to original, and the appraiser adjusts for that. If you plan to enlarge a house, ask the city how much floor area the lot allows before you count on it. The ground around the park is low, so it is sensible to check the flood map for the address.

South of Huntington Drive, San Marino runs down toward the Alhambra and San Gabriel city lines. The streets form a more regular grid than in the north, and San Gabriel Boulevard and Del Mar Avenue cross this part of the city. The shops along Huntington Drive and on Mission Street are close by.

Lots here are smaller than north of the boulevard, and the houses are more modest in scale: one-story and two-story homes from the 1920s through the 1940s, many of them traditional or ranch in style, with some rebuilt in recent years. This is where a loan in San Marino is most likely to fall near the conforming limit. With enough money down, a loan can stay at or under Los Angeles County’s one-unit figure. With less, it becomes a jumbo loan under a lender’s own rules, so it is worth working out both with Sam. Appraisals are usually direct, since comparable sales are regular. The same city rules on design and house size apply as in the north, and a garage conversion or back unit should have permits to be counted.
